Continuous carbonization equipment and tail gas treatment device thereof

Abstract

The invention discloses a tail gas treatment device. The tail gas treatment device comprises a condensing tar discharging tank, an acid mist purifying tower containing basic compounds and an incineration cabinet which are arranged sequentially along a tail gas delivery direction and communicated, the upstream of the condensing tar discharging tank is communicated with an exhaust branch communicated with a furnace body of carbonization equipment, and a discharge outlet communicated with external environment is formed in the incineration cabinet. In the working process, tail gas discharged from the furnace body is fed into the tail gas treatment device from the exhaust branch and then passes the condensing tar discharging tank, the acid mist purifying tower and the incineration cabinet sequentially, tar contained in the tail gas is condensed and collected sequentially, acids in the tail gas is subjected to acid-base neutralization treatment, carbonic oxide in the tail gas is incinerated to form non-toxic harmless gases such as carbon dioxide, and finally the treated non-toxic harmless gases are discharged to the external environment from the discharge outlet. The tail gas treatment device is high in treatment efficiency. The invention further discloses the continuous carbonization equipment applying the tail gas treatment device.

Description

technical field [0001] The invention relates to the technical field of carbonization treatment equipment, in particular to a tail gas treatment device. The invention also relates to a continuous carbonization equipment using the tail gas treatment device. Background technique [0002] Continuous carbonization equipment is a very common carbonization treatment equipment, and the tail gas treatment device is an indispensable working component in the main structure of continuous carbonization equipment, and its working performance is also increasingly concerned by people. [0003] At present, during the operation of existing carbonization equipment, it usually produces a large amount of exhaust gas, which generally includes tar, acid, carbon monoxide and other toxic and harmful substances, causing varying degrees of pollution to the production workshop and the surrounding environment. However, although the existing exhaust gas treatment device has a certain exhaust gas filteri...

Problems solved by technology

[0003] At present, during the operation of the existing carbonization equipment, it usually produces a large amount of exhaust gas, which generally includes tar, acid, carbon monoxide and other toxic and harmful substances, causing varying degrees of pollution to the production workshop and the surrounding environment

However, although the existing exhaust gas treatment device has a certain exhaust gas filtering and processing capacity, its processing function is relatively single, and it cannot completely filter a variety of harmful substances at the same time, and the exhaust gas treatment efficiency is low.
