The problem of staying in the organic solvent on absorber, causing adsorber regeneration low efficiency.To solve methylene chloride adsorber regeneration effect
The low problem of rate, the utility model provide it is a kind of for handle methylene chloride tail gas absorption activate device, device by
Line activation pathway thoroughly removes the organic solvent and moisture of residual on the adsorbent material, improves regeneration efficiency.
With reference to Fig. 2, the utility model is used to handle the absorption activation device of methylene chloride tail gas, including absorber 2, absorption
Device 2 is connected with tail gas adsorption pipeline 8 and desorption tube road 9 and activation line access 7, and activation line access 7 includes autocontrol valve
Door 6, blower 1, heat exchanger 3, demister 4 and vacuum pump 5, autocontrol valve 6, blower 1, heat exchanger 3, absorber 2, demister
4, vacuum pump 5 is sequentially connected by pipeline.
Wherein the adsorbent material in absorber 2 is carbon fiber；Wherein heat exchanger 3 can be used as heater and cooler, as
When heater, heat medium is steam, and when as cooler, cooling medium is recirculated water；Its intermediate pump 5 is Water-ring vacuum
Pump.
The absorption activation device for handling methylene chloride tail gas of the utility model further includes activation line control program,
Activation line controls setting activation time in program, activation temperature and pressure parameter in absorber.Activation line controls program
Existing control program, program can be inputted computer by those skilled in the art can be automatically controled activation time, absorber
Interior activation temperature and pressure.Activationary time realizes that temperature passes through tune in absorber by adjusting the folding of autocontrol valve
Refrigeration or the heating of heat exchanger are saved to realize, the pressure in absorber is realized by adjusting the vacuum degree of vacuum pump.
