Abstract

The invention discloses an air filter device of a gas furnace draught fan. The air filter device of the gas furnace draught fan comprises an air filter and a draught fan, wherein the upper end of theair filter is provided with an air inlet, a sealing cover is arranged on the air inlet, the lower end of the air filter is provided with an air outlet, the lower end of the air outlet is connected with an air inlet of the draught fan through a pipeline, and an air outlet of the draught fan is connected with a gas furnace; and the air filter comprises a shell, the top end of the shell is provided with a mounting plate, a main filter element is mounted on the mounting plate, the lower end of the main filter element is provided with a safety filter element, and the lower end of the shell is provided with a reverse blowing gas outlet pipe. By arranging the air filter, the draught fan, the air inlet, the air outlet, the main filter element and the safety filter element, the problem that the traditional draught fan easily sucks dust into the gas furnace causing the sprayer blockage of the gas furnace is solved.

Description

technical field [0001] The invention relates to the technical field of gas furnaces, in particular to an air filter device for induced draft fans of gas furnaces. Background technique [0002] Now in order to reduce environmental pollution, it is required to replace the previous boilers with gas furnaces. Gas furnaces can reduce the emission of pollutants, and the use of gas furnaces can also reduce the consumption of raw materials. The structure of the device with flue gas preheating and recovery is basically the same, mainly because the influence of the large difference in medium temperature is somewhat different. [0003] One disadvantage of the induced draft fans currently sold in the market is that there is no filter device at the entrance of the induced draft fan. In some production areas, there is a lot of dust outside. When the induced draft fan sucks the dust in for a long time, it will cause the nozzle of the gas furnace to be blocked. , the firepower is reduced, ...
