Gas purification treatment device and process with phenolic water treatment for two-sectional type gas producer

Abstract

The invention discloses a gas purification treatment device and a process with phenolic water treatment for a two-sectional type gas producer, which belongs to the field of gas producer wastewater treatment and gas cooling and purification. The gas purification treatment device comprises a phenolic water settling pond (1). The gas purification treatment device is characterized in that the phenolic water settling pond (1) is communicated with a phenolic water preheating tank (4) through a pipeline; a phenolic pump (2) is arranged in the pipeline; the outlet of the phenolic water preheating tank (4) is communicated with a phenolic water evaporator (6); the upper end of the phenolic water evaporator (6) is connected with a cyclone dust collector (5); a phenonlic water steam conveying pipeline (7) is arranged on one side of the phenolic water evaporator (6); and the lower end of the phenolic water evaporator (6) is connected with an air cooler (8). Due to adoption of the gas purification treatment device with phenolic water treatment for the two-sectional type gas producer, both the low-section gas waste heat can be sufficiently utilized, and the phenolic water can be treated without harm and effectively utilized, environment pollution is effectively prevented, and the economic benefits are improved.

Description

technical field [0001] A two-stage gas generator gas purification treatment device and process with phenol water treatment belong to the field of gas generator wastewater treatment and gas cooling and purification, and specifically relates to a two-stage gas generator gas purification treatment device capable of simultaneously treating phenol water and craftsmanship. Background technique [0002] A large amount of phenol water will be produced in the process of producing gas with a gas generator. This part of phenol water contains coal tar, coal fly ash and a small amount of light tar in addition to soluble substances such as phenol and toluene. The previous extensive practice was to directly discharge this part of phenolic water without any treatment, which caused great pollution and harm to the living environment of human beings. Discharge requirements, it must be treated harmlessly. In the prior art, the treatment of phenolic water is mainly by incineration method or...

Problems solved by technology

The previous extensive practice was to directly discharge this part of phenolic water without any treatment. This practice has caused great pollution and harm to the living environment of human beings. According to the discharge requirements, it must be treated harmlessly. Under the existing technology, the treatment of phenol water is mainly through incineration or biochemical methods. Both of these methods require special incineration equipment or biochemical equipment. The treatment process is complicated and the cost is high. High, not suitable for large-scale promotion

At the same time, due to the characteristics of its own process, the gas outlet temperature of the lower stage of the two-stage gas generator can generally reach about 450°C-550°C, which contains a large amount of heat energy and needs to pass through the large-area air cooler and intercooler at the back. Only after cooling can it be used, such a large air cooler not only increases the cost of cooling gas, but also a large amount of heat energy cannot be effectively used, wasting heat energy resources
