Abstract
The invention discloses an automatic control method for the cycling operation of an organic waste gas recovery adsorption tank. An organic waste gas recovery device comprises a dedusting cooling box, an induced draft fan, four adsorption tanks, a condenser and a separation box, wherein the adsorption tanks are used for finishing the continuous cycling processes of adsorption, desorption and regeneration. The cycling operation comprises the following steps: when the adsorption tanks 1, 2 and 3 are in adsorption states, the adsorption tank 4 is in desorption and regeneration states; in the next operation state, when the adsorption tanks 2, 3 and 4 are in the adsorption states, the adsorption tank 1 is in the desorption and regeneration states; and then the operation is cycled continuously, i.e., each adsorption tank in different operation periods is respectively in the adsorption state, the desorption state and the regeneration state. Therefore, by the operation of the adsorption tanks, the adsorption efficiency is improved effectively. The automatic control method is simple to operate and can achieve the high waste gas purification rate and the high solvent recovery rate.
Description
Technical field
The invention belongs to the exhaust-gas treatment field, relate to a kind of organic exhaust gas and reclaim adsorption tanks periodic duty autocontrol method.
Background technology
Organic exhaust gas is the modal pollutant that the industries such as coating production, paint, pharmacy, printing, papermaking, weaving and petrochemical industry are discharged.These organic exhaust gas majorities have toxicity can cause atmosphere pollution, and the mankind's health and environment all had harm.In recent years, along with the development of industrial technology, Organic Waste Gas Pollution is more and more serious, is also simultaneously a kind of waste to resource, and the recovery of research organic exhaust gas has very important realistic meaning.At present, the adsorption rate that domestic organic exhaust gas recovery Main Problems is organic exhaust gas is difficult to further raising, can not process discharging up to standard for high-concentration waste gas.
Summary of the invention
For the problems referred to above, in order to obtain higher adsorption rate, the invention provides the organic exhaust gas that a kind of adsorption rate is high, treatment effect is good and reclaim adsorption tanks periodic duty autocontrol method.
The technical solution adopted in the present invention is:
Air separator of oxygenerator comprises dedusting cooling box, air-introduced machine, adsorption tanks, condenser, separator box.Wherein said adsorption tanks have adopted 4 adsorption tanks structures, are used for completing the continuous circulation process of adsorption and desorption, regeneration.
Adsorption tanks periodic duty autocontrol method is: after organic exhaust gas is lowered the temperature through dedusting, sucked in adsorption tanks by blower fan, by the active carbon in fixed bed, it is adsorbed, when absorption is saturated, superheated steam is passed into adsorption tanks carry out desorption, after desorption is complete, to the adsorption tanks steam discharge, regenerate, the desorption product enters separator box through after condensation, obtains organic solvent after separation.This adsorption and desorption, regenerative process are continuous cyclic processes, and the loop control step is as follows: when adsorption tanks 1., 2., when 3. being in adsorbed state, 4. adsorption tanks are in detachment status; Next duty is that 2., 3., 2., 3. adsorption tanks are in adsorbed state, and 1. adsorption tanks are in detachment status, and so circulation is gone down.Each adsorption tanks is in respectively adsorption and desorption, reproduced state in the different operating period.
Compare with existing method, the usefulness of the inventive method is: solved the lower problem of the organic solvent rate of recovery that in traditional air separator of oxygenerator, adsorption tanks work alone separately and cause, coordinated by the work between each adsorption tanks to effectively raise adsorption efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
The organic exhaust gas that discharges in industrial processes is introduced in adsorption tanks by blower fan after lowering the temperature through dedusting, and organic exhaust gas passes NACF in adsorption tanks, and organic solvent is by carbon fiber adsorption and catalytic combustion, and purified gas is by adsorption tanks top discharge.
Enter desorption process after adsorption tanks absorption is saturated, superheated steam is passed into carry out desorption in adsorption tanks, after desorption is completed, to the adsorption tanks steam discharge, regenerate; The desorption product enters in condenser, enters in separator box through condensed organic solvent and water vapor mixture, obtains organic solvent after separation.
Adsorption and desorption, regenerative process are actually continuous cyclic process, and each adsorption tanks is in respectively adsorption and desorption, reproduced state in the different operating period.
Adsorption tanks periodic duty autocontrol method of the present invention is:
At first, tank 1 enters adsorption process, and air inlet, the air bleeding valve of PLC control this moment tank 1 are opened.
After tank 1 was completed an adsorption time, tank 2 also entered adsorption process, and PLC controls corresponding valve and opens, and this moment, tank 1 was still adsorption process.
After tank 2 was completed an adsorption time, tank 3 entered adsorption process, and this moment, tank 1,2 was still adsorption process.
After tank 3 was completed an adsorption time, tank 1 entered desorption, regenerative process, and PLC controls air inlet, the air bleeding valve of closing tank 1, opens its steam, tapping valve, and this moment, tank 2,3 was still adsorption process, and tank 4 also enters adsorption process.
After completing desorption, regeneration, tank 1 enters stand-by time; this moment, exhaust steam valve opened to reduce tank internal pressure and temperature; stand-by time is that the difference of adsorption time and desorption time is (according to the requirement of active carbon absorption technology; adsorption time should be slightly larger than desorption time; system has also designed interlock protection at this, if desorption time greater than adsorption time system can not work).
After completing, tank 1 standby enters adsorption process, tank 2 beginning desorptions, regeneration at this moment, and tank 3,4 still adsorbs.
After this 4 tanks will by process periodic duty like this, quit work until system obtains stopping signal.
Being more than preferred embodiment of the present invention, is not that the present invention is done any pro forma restriction, and every foundation technical spirit of the present invention all belongs in the scope of invention technical scheme any simple modification made for any of the above embodiments, equivalent variations and modification.
