Description

technical field [0001] The invention relates to a device for dewatering and drying treatment of emission source flue gas extracted by a continuous emission monitoring system for fixed pollution sources, in particular to an electronic refrigerator for continuous monitoring of flue gas. Background technique [0002] With the development of society, the advancement of science and technology, and the development of large industries, the requirements for environmental protection are getting higher and higher. Real-time monitoring and real-time processing are required. Therefore, the continuous emission monitoring system of fixed pollution sources is particularly important, and the continuous emission of fixed pollution sources The monitoring system needs to remove water and dry the extracted flue gas from the emission source before sending the treated clean gas to the analyzer for concentration analysis. Because the temperature of the flue gas from the emission source is high, it ...

AI Technical Summary

Problems solved by technology

The heat release surface is cooled by a fan, and the heat absorption surface is close to the refrigeration barrel. When the gas flows through the refrigeration barrel, the moisture in the flue gas will condense into water at a lower temperature, and will be discharged from the condenser to obtain clean gas. For the detection of the analyzer, although this device can perform dehydration and drying treatment of flue gas, it still has the following defects: 1. When the whole device is in a long-term working state, due to the heat dissipation on one side, the efficiency of dehydration and drying treatment of flue gas is low , the refrigerating sheet is often overloaded and burns out. 2. The device uses a semiconductor electronic refrigerating sheet with a heat-absorbing surface close to one end of the refrigerating barrel. When the humid gas is dewatered and dried by the refrigerating barrel, the other end of the refrigerating barrel has an obvious effect of dewatering and drying. The other is to use a compressor to refrigerate. The principle of refrigeration is the same as that of a refrigerator. The compressor compresses the refrigerant (ammonia or freon), the temperature rises, and it enters the radiator, exot...
