Embodiment

[0033] Embodiment: a kind of micro-negative pressure recovery circulation treatment system of VOCs purification treatment device, such as figure 1 and 2 As shown, it includes a gas collection pipe 1, a negative pressure pump 2 connected to it, a collection box 3 connected to the negative pressure pump 2, a delivery pipe 4 connected to the collection box 3, and a collection and processing system 5 connected to the delivery pipe 4, A pressurizing device 6 is arranged in the collection box 3 . The non-condensable gas in the VOCs that has been treated once enters the collection box 3 from the gas collection pipe 1 under the action of the negative pressure pump 2, and is subjected to pressurized collection treatment, so that the non-condensable gas in the VOCs returns to its original properties, and then enters the The collection and treatment system 5 performs purification work again, and effectively treats the purified waste gas (VOCs) again to realize the advantage of zero emis...

Abstract

The invention discloses a micro-negative pressure recycling and circulating treatment system of a VOCs purification treatment device, and belongs to field of coking industry waste gas treatment. According to the technical scheme, the system is characterized by comprising a gas collecting pipe, a negative pressure pump connected to the gas collecting pipe, a collecting box connected with the negative pressure pump, a conveying pipe connected with the collecting box and a collecting and treating system connected with the conveying pipe, and a pressurizing device is arranged in the collecting box. According to the system, the purified organic waste gas (VOCs) can be effectively treated again, and the effect of zero emission is achieved; and tar residues on the surface of the compression layerand the inner wall of the heat preservation barrel can be reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment in the coking industry, in particular to a micro-negative pressure recovery cycle treatment system of a VOCs purification treatment device. Background technique [0002] With the rapid development of the iron and steel industry, the coking industry has also made great progress, but the environmental pollution is also becoming more and more serious. As the country proposes policies such as capacity reduction and structural adjustment, environmental protection will be one of the rigid targets for the coking industry. Among the various environmental protection issues in the coking industry, the pollution of waste gas from the coking industry is particularly prominent. [0003] Coking industrial waste gas can be divided into inorganic waste gas and organic waste gas according to its chemical properties. Inorganic waste gas includes SO2, NOx, ammonia, H2S, etc.; organic waste gas (VOCs) is a genera...
