Embodiment Construction

[0015] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] figure 1 Shows a form of dust removal gas system for bag filter, the dust removal gas system includes a gas tank 2 for storing the dust removal gas, an electric heater 4 whose inlet is connected to the outlet of the gas tank 2, an inlet A plurality of gas distribution boxes 5 connected in parallel to the outlet of the electric heater 4, the inlet of the gas tank 2 is connected with a screw compressor 1, and the dust removal gas is pressurized into the gas tank 2 for storage through the screw compressor 1, and the dust is removed Compressed air is used as the gas, and a freeze dryer 3 is connected between the gas tank 2 and the electric heater 4. Through the freeze dryer 3, the soot-cleaning gas is dew-free to remove the moisture in the soot-cleaning gas before heating, and the soot-cleaning gas After the moisture is removed by the freeze d...

Abstract

The invention discloses a deashing gas heating system for preventing dewing in bag filtration. After deashing gas is discharged from a gas tank, the deashing gas is heated by an electric heater, the heated deashing gas enters a gas distribution box, and after the deashing gas reaches proper pressure and temperature, the deashing gas is blown to the bag wall of a dust bag through a pipeline, so that the dust dewing and caking conditions are eliminated, dust can be removed from the dust bag smoothly and the quality of the dust is ensured.

Description

[0001] technical field [0002] The invention relates to a cleaning gas heating system for bag type dust removal and anti-condensation. Background technique [0003] The bag filter filters the flue gas through the dust bag, and then blows it with the dust removal gas to make the dust accumulated on the wall of the dust bag fall down. However, due to the low temperature of the cleaning gas, the dust condensation on the bag wall is caused, making it difficult to remove the dust from the bag wall, and this will reduce the quality of the dust. Contents of the invention [0004] The purpose of the present invention is to provide a system capable of heating the cleaning gas on the bag filter, so as to avoid dust condensation and ensure the quality of dust. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: a bag-type dedusting and anti-condensation cleaning gas heating system, including a gas tank for storing the cleaning ...
