Should fireproof data industry choose why to be planted does industrial workshop remove dust equipment?

In the process that environmental protection transforms, the problem is in basically centrally desulphurization, take off saltpetre, remove dust these a few respects, the manufacturing unit drag in of finished product brick arrives high temperature kiln, so desulphurization takes off saltpetre and workshop to remove dust must synchronous, but manufacturer of a few indeterminate form and raw material workshop, the workshop removes dust also must want to do.

1, what does the dustproof measure of fireproof material factory have?

In the manufacturing process of fireproof material, have many dust generation. The generation to reduce dust as far as possible and make the worker is not contacted with dust, can take the following and integrated step: (1) uses sound manufacturing technology to reduce dust concentration;(2) to realize manipulator instrument to change automation to improve work requirement;(3) to strengthen constituent management, perfect and dustproof system.

Dustproof concrete step is as follows:

(Of 1) stock add wet stock add wet the generation that can reduce dust significantly. Can add wet stock to clay of silica, horniness, tall aluminous alumina, grog, useless brick waits. All sorts of stock allow increasing wet amount is not identical, basically depend on following element: Of stock the biggest the when moisture; equipment runs first productivity; that contains raw material of wet quantity; machines evaporate of moisture of process each working procedure to send circumstance; of all sorts of bricks shape moisture.

(Of the airtight equipment of 2) equipment airtight it is dust limitation is in local limits, for inspiratory remove dust creation condition. Airtight form can divide the device that often uses in fireproof material production the following kinds: (1) is local and airtight cover: The part equipment raise dirt is airtight inside the cover, apply to concentration continuously Yang Chen and in instantaneous pressure boost not big dirt source. The characteristic of local and airtight cover is the overhaul need to demolish whole and sealed cover when equipment, use in the place of seldom overhaul on equipment commonly consequently, if the canister is ground of machine present makings opening. (2) half airtight cover: Outside removing equipment transmission part, close entirely inside the cover, stay have observation hole and operation door. This kinds of airtight cover applies to the equipment of comprehensive Yang Chen, if work,grind machine. Its characteristic is a product treatment undertakes completely inside airtight cover, the worker is operated outside the cover, the worker when jockeying can enter the overhaul inside the cover, also must demolish airtight cover when equipment heavies repair. (3) whole is airtight cover or little airtight room: Yang Chen equipment is all and airtight inside the cover, frequent to the overhaul and the raise dirt device that uses inconvenience of half airtight cover, can use this kinds of airtight type, be like vibrating separator. Its characteristic is product treatment undertakes inside the cover, jockey person can enter the overhaul inside the cover at any time, airtight cover also need not be demolished when equipment heavies repair.

2, does structure of airtight to equipment cover have why to ask?

Airtight cover structure should accord with equipment to ask below: (1) structure should be mixed stably close, the juncture of airtight cover is in because equipment vibration, makings piece collides,do not answer etc lose close sex. (2) does not affect normal operation of the worker, should leave operation door. (The convenience of 3) mature equipment when the overhaul, put apart inspects hole necessarily. (The aperture of 4) airtight hood, door falls in contented operation condition, dimension should the smallest.

3, which a few shares does dust collector include?

Dust collector includes aspiration unit (the suction that dust shield or inspiratory dust use wind mouth) , the carriage conduit of the gas that contain dirt, dust is amiable the separate facility of body (various dust catcher) , the exhaust of kosher gas (platoon fan) wait for a part.

4, does the choice remove dust what main item should equipment consider?

The choice removes dust the following should consider when equipment:

(1) dust property: The germ of dust happening and the condition that produce, all property of the dust amount that produce and dust of its chroma; (the characteristic of dust of chemical composition, granuality, density, temperature, moisture absorption quantity, electrified state (harmful gas, radioactivity) of;(2) dust reclaim method or expectation of processing technique;(3) obtain remove dust, import dust concentration and the chroma;(4) cost that export dust namely, remove dust namely the necessary dynamical cost that the investment of equipment, place takes up the place when space, movement needs, safeguard administration fee to wait. If the choice is wet,consider even when dust catcher after water consumption is mixed, the processing of slop reclaims problem.

In actual in should choose dust catcher by the following circumstance:

Common circumstance can choose tornado dust catcher, if cannot depart dust adequately,come out, can be in hind paragraph add with bag type dust catcher.

Circumstance of thick graininess dust uses tornado dust catcher the most appropriate. Wear and tear and generated fine noodles or vermicelli made from bean or sweet potato starch can add after bag type dust catcher will depart.

Dust granuality is for the most part it is very difficult that when be less than 3/um, market is caught with tornado dust catcher, can choose bag type dust catcher or wet dust catcher.

Change in dust oar reclaim or the circumstance of deserted advantage, can choose all sorts of wet dust catcher.

5, remove dust what does the reason that conduit jams have?

Remove dust the reason that conduit jams has: 1) stock produces the moisture that heat makes itself is contained to evaporate in machining a process. Vapor by inspiratory remove dust conduit is cooling condense into water, add at dust of tube wall felt and make conduit jams gradually. The dip of 2) conduit under dust rest horn (° of 25 ° 50) when, the dust inside conduit won’t slide by oneself and cause jam. The air velocity of flow inside 3) conduit is too little, make dust cannot stay along with air current motion inside horizontal canal to cause conduit to jam.

6, remove dust can be equipment divided a few kinds be?

Remove dust equipment can divide according to the property of active force it is 4 kinds: (1) falls dirt room: Dust is sedimentation as a result of gravitational action. (2) tornado dust catcher: The centrifugal force of the generation when using the air current that contain dirt to move in circumgyrate makes dust sedimentations. (3) filters type dust catcher () of bag type dust catcher: Make course of the air current that contain dirt filters content and purify, dust grain is as a result of what be stayed to adhere by block and catch market. (4) report dust catcher: Make dust electrified below action of high-pressured electric field, go up to the electrode that records same charge mobile, then is counteracted to lose charge and be arrested collect.

Press working principle, dust catcher can be divided again mix for dry type dust catcher wet dust catcher two kinds.

By purify degree to be able to divide it is 3 kinds big: (1) is thick purify: Can catch the grit of collect 100/um above, its efficiency is in 90% above. When to Gao Chen pH indicator gas uses multistage to purify, thick purify what can satisfy the first class only to purify a requirement. (Purify in 2) : Can catch the grit of collect 10um above, its efficiency is in 90% above. When basically comprising Ju Hanchen chroma to not be more than 2g/m3 with bulkier grain when the dust in gas, in using one level, purify remove dust equipment can satisfy a requirement. (3) is fine purify: Can catch the grit of collect Lum above, its efficiency is in 90% above. When gas medium dust basically is bulkier grain composition, the requirement removes dust fine purifying device can be used when efficiency achieves 98% above.

7, of tornado dust catcher remove dust what is the principle? What advantage is there?

Of tornado dust catcher remove dust the principle is: The gas that contain dirt enters tornado whirligig is made produce centrifugal power inside dust catcher, what because dust is mixed,enrage body density is different, make both detached. The granuality that leaves heart muscularity, dust accordingly big, chroma departs greatly, easily.

The advantage of tornado dust catcher is a structure simple, it is easy to make, low-cost, cover an area of an area small, remove dust efficiency is taller.

8, what characteristic does bag type dust catcher have?

Bag type dust catcher is to use organic fiber or inorganic fiber cloth to filter the dust in gas the purifying device that come out, agree with the processing blame caking property, industry dust that is not fibroid to work. Its advantage is to remove dust efficiency is tall, dust can amount to 99% above under 5um, with wet dust catcher photograph is compared, dust reclaims use convenient, do not need winter prevent frostbite. Its defect is filter cloth is used up more, type of cost specific humidity removes dust equipment is high, vapor and processing should be contained in gas easy when bibulous hydrophily dust, filter cloth is adhesion dust is easy cause jam, and unfavorable use at handling high temperature to contain dirt gas.

9, of electric dust catcher remove dust what is the principle? He You is nodded?

Of electric dust catcher remove dust the principle is to use corona discharge to make dust particle electrified, electrified below electrostatic action dust particle builds up at dust collection extremely on.

The advantage of this dust catcher is: Remove dust efficiency is tall, in principle but will energy of; of all dust eliminate is used up in gas little, it is OK that processing 1000m3 gas makes an appointment with 0.10.8kW/h; of bad news report processing provides mordant aeriform; unit process of cargo bandling high to be able to achieve complete automation blandly. .
