[dried food] what does RTO device have in the application in off-gas treatment of cooking VOCs industry?

Cooking waste gas contains bitumen smoke, benzene and Bi and benzene kind wait for harmful material, if be discharged directly, can cause air pollution, affect zoology environment of place. Next small write the application in telling about RTO device to be administered in cooking VOCs waste gas for everybody.

Some cooking chemical plant is manufacturing benzene kind, phenolic kind, naphthalene kind, colophony kind, salt kind the coal chemical industry that waits for chemical product to give priority to uses a company integratedly, tar process capability is 100 thousand T/a, process capability is benzene 30 thousand T/a, provided rich raw material for the product such as synthetic fibre, paint, dye, medicine, pesticide, chemical fertilizer. Meanwhile, the cooking industry waste gas that this chemical plant can produce temperature to be 50 ℃ of 20 ～ , discharge to be 4000 ～ 18000m3/h in producing a course normally, its are basic if the watch is shown 1 times,composition and content convert data.

According to the country the regulation of standard of relevant industry exhaust emission, if want to amount to organic industry off-gas treatment mark, the large RTO that need comprises by 3 regenerator undertakes depurative. The 3 rooms RTO that this project uses is 1 increased to blow on the foundation of two rooms sweep with regenerator, if pursue,1 is shown.

When RTO moves normally, of industrial waste gas be finished into gas and exhaust through valve switch. In cycle of the 1st job, regenerator of A of classics of from bottom to top of industrial waste gas warms up, enter firebox oxidation to give off heat next; After oxidation exothermic ends, from above to below passes B regenerator, with accumulation of heat indoor filling has heat exchange, deliver quantity of heat B regenerator, repass craft pipeline enters chimney to discharge; right now C regenerator is in blow sweep state, with blow sweep fan general regenerator (the air chamber that contain part) stop mediumly processing of oxidation of firebox of inbreathe of industrial waste gas, because the switch process of regenerator affects efficiency of industrial off-gas treatment,prevent. In cycle of the 2nd job, a regenerator is in blow sweep state, from bottom to top of industrial waste gas enters B regenerator, with after already absorbing caloric filling to have heat exchange, enter firebox oxidation exothermic, again from above to below passes C regenerator, after delivering quantity of heat C regenerator, enter chimney. In cycle of the 3rd job, b regenerator is in blow sweep state, industrial waste gas is entered by C regenerator, after oxidation is radiative, enter chimney through A regenerator, completed 1 when RTO device moves old cycle, move alternately so. Heat below isolation air condition when soft coal 1050 ℃ of 950 ～ , wait for level through the dry, carbonization that heat up solution, melt, cohere, solidify, systole, get coke finally, this process calls coking plant.

The waste that coking plant process generates is gas can get the basic and chemical raw material such as a variety of balmy hydrocarbon and heterocyclic compound through reclaim and refining, the Jiao Lu that arises at the same time is gas it is fuel of high calorific value, can use generate electricity or supply a city gas. Accordingly, this project with the sources of energy efficient use for the purpose, use Jiao Lu gas replace auxiliary fuel, OK and managing cost, raise Jiao Lu gas utilization rate, can satisfy the fuel requirement when RTO device moves normally at the same time. This unit is main by firebox, regenerator (the air chamber that contain part) reach transfer valve door to comprise.
