Coal-gas producer phenolic water treating device and treating process

Abstract

A gas producer phenol water treatment device and a treatment process thereof belongs to the filed of gas producer equipment, comprising a gas producer. A primary dust collector is arranged on the side wall of the gas producer. The device is characterized in that the primary dust collector (2) is connected with a phenol water evaporator (7) by a gas pipe line (3). The phenol water evaporator (7) is connected with the phenol water treatment device. The bottom of the gas producer (1) is provided with a tee (12). The phenol water treatment device and a bottom process fan (8) are respectively connected with an air-steam mixer (11). The air-steam mixer (11) is connected with the tee (12) and the gas producer (1) by a pipe. The gas producer phenol water treatment device and the treatment process thereof can completely solve the pollution problem of the water containing phenol and protect the environment, and at the same time, the device has a simple structure. The phenol water is evaporated at a high temperature by the above devices. The phenol water stream enters into the air-steam mixer (11) to mix with the air of the bottom process fan (8), and then the phenol steam is sent into the burning layer of the gas producer (1). The device has simple process.

Description

technical field [0001] A gas generator phenol water treatment device and a treatment process belong to the field of gas generators. Background technique [0002] At present, most of the phenol water treatment methods use incineration or biochemical methods. Incineration method: spray phenol water into the incinerator to make the phenolic organic matter oxidize at a high temperature of about 1100°C, and finally generate CO 2 and H 2 O emission, this method is simple in process and easy to operate, but it consumes a lot of energy and investment. The cost of incinerating 1 ton of phenol-containing wastewater is about 200 yuan. At present, most manufacturers have stopped using it due to high costs. Biochemical method: The biochemical treatment of phenolic water is to cultivate microorganisms, and use microorganisms to digest, absorb and decompose phenolic organic matter in sewage into CO 2 and H 2 O process, the biochemical method has strict requirements on the water quality...

AI Technical Summary

Problems solved by technology

Biochemical method: The biochemical treatment of phenolic water is to cultivate microorganisms, and use microorganisms to digest, absorb and decompose phenolic organic matter in sewage into CO 2 and H 2 O process, the biochemical method has stricter requirements on the water quality of the sewage entering the biochemical pool. The concentration of organic matter such as tar and phenol in the sewage should not exceed the concentration that microorganisms can bear. Otherwise, the sewage needs to be diluted before entering the biochemical pool. At the same time, the microbial domestication is relatively Difficult, the influent concentration exceeds the standard, and the ambient temperature is not suitable, which can easily limit the survival of microorganisms. According to the different ways of carrying microorganisms and oxygen supply methods, this method can be divided into aeration method, contact oxidation method, biological turntable method and biological method. filter method, etc., this method occupies a large area, requires high investment, and is cumbersome to operate
