Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] A coke oven sampling gas pretreatment equipment includes a front-end sampling pipeline 1, a combined water washing tank 3, a water washing filter tank 4, a steam jet pump 5, a filter screen 6, an organic storage tank 7, a cyclone refrigerator 8, and a combined filter Tank 9, sewage pipeline 11.

[0032] A filter screen 6 is installed in the front-end sampling pipeline 1 , and the outlet of the front-end sampling pipeline 1 merges with the outlet of the steam jet pump 5 . The outlet of the steam jet pump 5 is connected with the water washing filter tank 4 installed in the combined water washing tank 3 through a pipeline, the upper part of the combined water washing tank 3 is connected with the lower part of the organic storage tank 7 through a pipeline with a valve, and the upper part of the organic storage tank 7 is connected by a belt The pipe with valve is co...

Abstract

A coke oven sampling gas pretreatment device includes a front-end sampling pipeline 1, a combined water washing tank 3, a water washing filter tank 4, a steam jet pump 5, a filter screen 6, an organic storage tank 7, a cyclone cooler 8, a combined filtering tank 9, and a sewage discharging pipeline 11. The coke oven sampling gas pretreatment device has the beneficial effect that the coke oven sampling gas pretreatment device can ensure the continuous sampling, hydrogen sulfide corrosion of the coke oven sampling gas pretreatment device can be avoided, meanwhile aqueous vapor in a sampling gas can be reduced, and aqueous vapor reduction facilitates improvement of the calculation precision.

Description

technical field [0001] The invention relates to the technical field of coke oven safety, in particular to a pretreatment device for coke oven sampling gas. Background technique [0002] In the recovery and purification process of coke oven gas in coking plants, oxygen content is an important control index. Coke oven gas contains a large amount of highly viscous and easily crystalline substances such as tar and naphthalene, which can only be reused after high-voltage electrostatic decoking. Before entering the electric coke capture, the oxygen content in the gas must be continuously analyzed. The control indicators are: when the O2 content > 0.8%, it will alarm, and when the O2 content > 1.0%, it will send a shutdown signal to cut off the electric coke capture power supply. [0003] However, existing sampling equipment and analysis methods have the following deficiencies: [0004] 1. It is impossible to effectively remove the influence of tar mist in the sampling gas ...
