On-line preprocessing system for coke oven smoke component analyzer

Abstract

The invention discloses an on-line preprocessing system for a coke oven smoke component analyzer. The system comprises a coke oven smoke sampling device, a desulfurization dehumidifier and a dehydration device, wherein one side of the coke oven smoke sampling device is connected with a primary filter by a heat tracing pipe; the other end of the heat tracing pipe is connected with the dehydration device; the dehydration device is connected with the desulfurization dehumidifier by a conveying pipe; one end of an outlet of the desulfurization dehumidifier is connected with the filter by a conveying pipe while the other end of the outlet of the desulfurization dehumidifier is connected with a sampling pump by a conveying pipe; the sampling pump is connected with a refrigerator by a conveying pipe; a peristaltic pump is arranged on the refrigerator; an outlet end of the refrigerator is connected with a voltage-stabilizing and current-stabilizing device by a conveying pipe. According to the system disclosed by the invention, aiming at the characteristics of high temperature, high humidity, heavy dust, acidity and the like of the coke furnace smoke, impurity removal and filtration measures are pertinently arranged, and clean, stable and reliable target sample gas components are provided for the analyzer to detect elements.

Description

technical field [0001] The invention relates to the field of automatic detection, in particular to an on-line coke oven flue gas component analyzer sampling gas pretreatment system. Background technique [0002] In the process of coking, in order to accurately control the amount of supplied gas and air, it is necessary to carry out online real-time detection of the components of the supplied gas and the flue gas after combustion. As for the components of the coke oven flue gas, there are relatively mature sampling methods on the market. However, they all face a common problem - the sampling pipe is easily blocked, the components are easy to corrode, the maintenance cycle is short, and the maintenance amount is large, all of which are caused by the imperfect pretreatment system of the instrument and equipment. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an online coke oven flue gas compon...
