The hair that industrial workshop removes dust shows shape to analyse

Spend to the contribution of air pollution as industrial dust taller and taller, the country discharges a standard to also rise in year after year to industrial dust, industrial workshop removes dust equipment also changes ceaselessly. The basis removes dust the characteristic of means, does the device that removes dust at present basically have: ? Dust catcher of report of? of wine of  party  , wet dust catcher, filter type dust catcher.

1. Mechanical dust catcher points to normally use quality power (gravitational, force and centrifugal force) the device that action makes grain content and air current detached, include gravitational expansion chamber, inertial dust catcher and tornado dust catcher to wait. This kind removes dust systematic cost is low, maintenance management is handy, but can sedimentation only big grain dust, and cause Yang Chen easily 2 times.

2. Report removes dust is to contain dirt gas to be in the process that has electric power through high-pressured electric field, make grit electrified, make below the action of electric field force grit deposit is on dust collection pole, one kind when make grit comes out from the depart in the gas that contain dirt removes dust equipment removes dust this kind systematic processing efficiency is very tall, wind block small; but one-time devoted cost is very high, and life is brief, maintain cost tall. Dry to processing dust has cause fire hidden trouble.

3. Wet dust catcher is to make contain gas and liquid (it is water commonly) intimate contact, the function of inertial collision etc that uses water and grain catchs collect grain or the device that make bead diameter increases. This kind of purifying device can divide dust not only, still can purify gas; Efficiency is taller, body of processing high temperature, can high humidity (drop in temperature) , will catch fire, explosive possibility is decreased to lowest. But, there is body refuse in handling a process; Prevent frostbite facility needs in the winter; Do not apply to the clean ability in swimming that change abhor and water rigid dust;

4. Filter type dust catcher, it is to make the air current that contain dirt is passed filter the device catching market of intercept of material general dust. Use fiber basketwork to do the bag type dust catcher that filter expects, in industrial tail gas remove dust respect application is wider. To fine dust (0.5 μ of ≥ M) removes dust efficiency is tall, amount to 99% above commonly, can use in purify the circumstance with very high demand. Facilitate reclaim stock, wait for pollution 2 times without pollution, liquid waste. But, suffer what filter expects to be able to bear or endure lukewarm, anti-corrosive the limitation that waits for function, use temperature cannot exorbitant, a little caustic gas also cannot be chosen. In catch market agglutinant reach by force hygroscopic when the flue gas with strong dust or processing very high dew point, jam easily filter bag, the influence works normally. The existence of different level occupies bag type dust catcher the ground accumulates bag of big, filter easy attaint, upkeep costs is advanced problem.

5. Adsorptive sex dust catcher, weigh an inhaler again, it is to make contain dirt air current the unit catching market that through filtering material allows dust adsorption dirt gas is detached. Average adsorptive data is activated carbon. This kind removes dust the system is very expensive to the efficiency catching market of little grain, but after activated carbon adsorption is saturated, need changes often, and one-time devoted cost is very high. Later period maintains cost tall also. Unsuited use at weighing dust environment.

The serious rate that follows air pollution is deepened ceaselessly, and Everyman is right but inspiratory sex dust is paid attention to more and more to human body harm, industry discharges standard year after year to raise the small grain content under;10um diameter to handle is to remove dust the certain way of equipment. But according to existing technical measure, cope with small grain content to diffuse, still be the effect processing of content of small grain of air of not quite ideal; is to had become industry to remove dust the issue that extremely urgent needs to solve!
