Desorption of adsorption of activated carbon of limited company of equipment of environmental protection of Zhejiang grand rich, company of professional off-gas treatment, type of waste gas accumulation of heat catalytic combustion, purify efficiency to be as high as 99% , waste gas Rco, processing of organic waste gas is chosen guarantee blue environmental protection, quality is reliable, operation fare is low, moving cost is low, below small make up introduce to everybody with respect to equipment of second birth of activated carbon desorption:

One, overview of equipment of second birth of activated carbon desorption

Equipment of second birth of activated carbon desorption

Equipment of second birth of activated carbon desorption is to use hot air to blow the activated carbon that sweeps adsorptive saturation, make adsorption is in the organic matter on activated carbon departs from activated carbon, in order to rehabilitate its adsorption property, achieve thereby repeat use end.

2, principle of technology of equipment of second birth of activated carbon desorption

Pass catalytic combustion desorption, restore ability of activated carbon adsorption, the setting inside catalytic purifying device increases hot cell, start add shrinkage fitting buy, enter in-house loop, when heat source reachs organic matter boiling point, organic matter is sent from the brandish in activated carbon, enter catalytic room to undertake catalysis is decomposed water and 2 oxygen China carbon, release an energy at the same time. Use the energy that releases to be in when entering adsorptive bed desorption, add hot device dead stop to work right now, organic waste gas preserves nature in interior of catalytic combustion room, tail gas gets depurative, undertake circularly, depart completely from activated carbon interior till organic matter, decompose to catalytic room. Activated carbon gets second birth, organic matter also gets decomposing handling. Whole catalysis purifying device is one whole, heat exchanger, add reative cell of shrinkage fitting buy, catalysis, fire extinguishing system to be an organic whole beforehand, form a bulk small, structure run stream of compact, air current the system of free.

3, the second birth that how equipment of activated carbon adsorption, desorption, catalytic combustion realizes activated carbon and use?

Activated carbon is one kind basically presents black by the exterior that contains material with carbon element to be made, in-house hole structure develops, material of element of carbon of a bigger than expressing an area, adsorptive capability is strong kind of small crystalloid. There is small opening in activated carbon material, in material of 1 gram activated carbon small hole, the watch after its spread out the area can be as high as 800 — 1500 square metre, of special purpose taller. There is small opening in activated carbon material, in material of 1 gram activated carbon small hole, the watch after its spread out the area can be as high as 800 — 1500 square metre, of special purpose taller. When the adsorptive chroma of activated carbon reachs fair value, won’t undertake adsorption again, at that time activated carbon can have lost filter the function of organic waste gas, at that time with respect to need device of the catalytic combustion that start realizes the desorption of activated carbon and second birth function.

Adsorptive quantity of material is those who follow temperature is elevatory and reduce, the temperature sorbent is elevatory, can make already was come down by adsorptive constituent desorption, this kind of method also is called become lukewarm desorption, the temperature in whole process is periodic change.

When equipment of activated carbon catalytic combustion undertakes desorption, second birth, power source of room of warm-up of device of the catalytic combustion that start, air warm-up, the box of aeriform classics mixed flow after warm-up is counteracted enter adsorptive case, after be heated of the activated carbon in box, the dissolvent of activated carbon adsorption volatilizes come out, solvent classics fan sends catalytic combustion room combustion, decompose the hot air such as CO2 and H2O vapour, hot air returns box of activated carbon adsorption to continue to heat to activated carbon partly, another part heats up air platoon sky, hot air interior circulates for many times activated carbon can get second birth.

The activated carbon after second birth had the function of adsorptive and organic waste gas again, achieve repeat use, managing cost.

4, technology of equipment of equipment of second birth of activated carbon desorption

1. By the organic gas that place of adsorptive canister eliminate contains, solvent by activated carbon adsorption, this sorbent (activated carbon) have adsorption and desorption double function. Specific technology move is as follows:

(1) gas enters adsorption of canister of adsorption of activated carbon of the reentrance after waste gas purifies a tower below normal temperature.

(2) whole and adsorptive process is to be in almost often press normal temperature case next undertaking, the sorbent in adsorptive tower (activated carbon) assentation in order to suck reclaim solvent serves as main purpose. Solvent reclaims condenser, vapour, cooling water, segregator as reclaim the main facility of solvent and support features.

2. Principle of activated carbon job separates branch, it is adsorptive, 2 it is desorption second birth, 3 it is activated carbon dry processing.

A, adsorptive process:

After waste gas purifies a tower through waste gas, gas enters activated carbon bed inside, after passing adsorption of the activated carbon inside the bed, (solvent is held back here adsorptive) accord with those who discharge a standard to purify aeriform eduction, via fan the platoon arrives outdoor.

Renewal process of B, desorption:

Activated carbon uses adsorption of period of time certain dissolvent (the content in gas mixes basis of use time length to produce time length and be decided) should make second birth, vapour is used to undertake desorption second birth to activated carbon when second birth, the dissolvent the adsorption in activated carbon is analytic below high temperature condition, repass condenser condensation enters segregator into the liquid, reclaim the dissolvent that go out and water undertake depart in segregator.

C. Activated carbon is dry

3. Dry fan beats normal temperature air activated carbon filter above all in, partial gas becomes water in this condensation, heat into travel heater again next air, hot air enters activated carbon filter circularly, give the air area that contains moisture content condensation, circulate so.

(3) the velocity of flow that gas enters activated carbon is spent to be less than 0.8 meters / second, can assure the adsorptive result of activated carbon so. Activated carbon fills a ply to achieve 600mm, assure adsorptive 90% efficiency effectively.

(4) set dry fan, after desorption ends, undertake to damp activated carbon dry, in order to assure below one round of adsorption of activated carbon.

(5) when activated carbon is dry, set an air heating apparatus, assure dry result.

(6) canister of activated carbon adsorption uses A3 armor plate to make. Flange has connective place to use 4 fluorine anticorrosive.

(7) the adoption of activated carbon Ningxia activated carbon, iodine number 900 above.

This plan is used first desorption of aeriform pretreatment adsorption is dry. In analytic desorption while, provide vapour source, cooling loop water, solvent reclaims condenser, the support features such as segregator. Fan is convulsions of negative pressure form. System of a complete set of uses PLC programme controll, man-machine interface, implement automation entirely.

Environmental protection of Zhejiang grand rich is desorption of an activated carbon, equipment of second birth of activated carbon desorption, production of manufacturer of equipment of activated carbon desorption is made, major offers solution of construction of industrial off-gas treatment for the enterprise
