Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0023] Such as figure 1 As shown, the present invention provides a biological treatment system for volatile organic waste gas, including an adsorption concentration device, a biodegradation device and a PLC control unit. The organic waste gas is controlled by the PLC control unit through the adsorption concentration device and the biodegradation device to achieve Treatment of organic waste gas.

[0024] The adsorption and concentration device includes a molecular sieve runner 30. The circumferential direction of the molecular sieve runner 30 is sequentially provided with an adsorption zone 31, a regeneration zone 32 and a cooling zone 33 that rotate in sequence, and the temperature of the regeneration zone 32 is controlled between 100 and 120 degrees. The adsorption zone 31, the regeneration zone 32 and the cooling zone 33 are respectively isolated f...

Abstract

The invention discloses a volatile organic waste gas biological treatment system comprising an adsorption concentration device, a biodegradation device and a PLC control unit, wherein the adsorption concentration device comprises a molecular sieve rotation wheel; an adsorption area, a regeneration area and a cooling area which rotate in sequence are arranged in the circumference direction of the molecular sieve rotation wheel; the inlet side of the adsorption area is connected with an adsorption fan; the outlet side of the adsorption area is communicated with a high-altitude chimney; high-temperature regeneration gas is arranged in the regeneration area; the outlet side of the cooling area is connected with a heat exchanger; one side of the heat exchanger is connected with the biodegradation device; the other side of the heat exchanger is connected with a heater; the heater is communicated with the regeneration area and backflows to be connected to the heat exchanger; the biodegradation device comprises a desorption fan, a regeneration liquid storage tank, and a nutrient liquid storage tank; the regeneration liquid storage tank is internally provided with a biodegradation rotation wheel; and the desorption fan is communicated with the biodegradation rotation wheel by a pipeline. The volatile organic waste gas biological treatment system disclosed by the invention is easy to operate, wild in reaction condition, low in running cost, free of secondary pollutants, high in removing efficiency, high in degree of automation, and good in safety performance, and the waste gas removing rate can be 98% or more.

Description

Technical field [0001] The invention relates to the field of comprehensive waste gas treatment, in particular to a volatile organic waste gas treatment system. Background technique [0002] The research and application of the treatment of volatile organic waste gas are relatively late. With the development of industrialization, the quantity and quantity of volatile organic waste gas generated by various industries (such as printing, pharmaceuticals, petrochemical, painting, painting, leather, electronics, etc.) The variety is also increasing. The current treatment methods for organic waste gas mainly include the following three: combustion process, adsorption recovery process, and oxidation decomposition process: [0003] The combustion process is mainly to decompose organic waste gas into stable small molecules of harmless substances through high temperature decomposition; [0004] The adsorption recovery process is mainly used for the adsorption and recovery of valuable organic s...
