Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments.

[0030] The invention provides a coking industrial waste gas treatment tower:

[0031] The bottom of the tower is provided with an exhaust gas inlet 1, and the top of the tower is provided with an air temperature regulator 7 and an exhaust gas outlet and a fan. The exhaust gas outlet (not shown in the figure) is connected to the condensation recovery device and used as a condensing medium. The fan includes a packing treatment tower The exhaust fan for extracting the gas and the blower for sending the purified gas into the condensation recovery device; wherein the air temperature regulator 7 and the fan can be an integrated device (attached to the present invention) figure 1 The air temperature regulator is integrated with the fan). After purification, the exhaust gas enters the air temperature regulator to be cooled to 20-40°C, and then the gas is sent to the condensation recover...

Abstract

The invention provides a coking industrial waste gas treatment tower, which is internally provided with a multi-stage filter, a heat exchanger and a multi-stage spraying unit. According to the invention, coking waste gas is subjected to multi-stage filtration treatment, heat exchange treatment and spraying treatment, so that the coking waste gas is purified and then can be used in the condensationrecovery of other gases, wherein the heat exchange can reduce the temperature of the coking waste gas and can take the part of the heat energy as the power of an air temperature regulator so as to reduce the energy consumption and save the energy, and particularly the secondary heat exchange can further reduce the temperature of the waste gas and promote the dissolution of substances un-dissolvedin a spraying liquid originally in the waste gas so as to improve the purification effect.

Description

Technical field [0001] The invention relates to waste gas treatment, in particular to a coking industrial waste gas treatment tower, and also relates to a treatment method. Background technique [0002] The exhaust gas emitted by coking production mainly comes from coal preparation, coking, and chemical product recovery and refining workshops. Among them, the coking process discharges large amounts of exhaust gas, high dust concentration, and toxic and harmful pollutants, such as benzene. Solubles (BSO), polycyclic aromatic hydrocarbons (PAH), sulfur dioxide, nitrogen oxides, hydrogen sulfide, carbon monoxide and ammonia, etc., among which benzene solubles (BSO) and polycyclic aromatic hydrocarbons (PAH) are also potential carcinogens. It is an important substance for environmental pollution control. At present, the coking waste gas treatment and recovery process needs to be improved. Summary of the invention [0003] In order to solve the above technical problems, the present i...
