Embodiment Construction

[0023] The specific structure and implementation of the present invention will be described in detail in conjunction with the accompanying drawings.

[0024] see figure 1 , which is a structural schematic diagram of a gas combustion filter according to an embodiment of the present invention. The filter includes a housing 2, which is rectangular in shape and whose size is much larger than the diameter of the gas delivery pipeline, and which is filled with a filter screen for filtering gas 3. There are openings at both ends of the housing 2, one of which is connected to the gas delivery pipeline, and an elbow 4 protruding toward the inside of the housing 2 is fixed at the opening at the other end. In this embodiment, the elbow 4 is a U-tube. Gas outlets 6 after the purifier are distributed on the elbow 4 of the filter. The shape, size and distribution of the air outlets 6 are not limited, and the optimal size is a circular outlet uniformly distributed along the elbow. The out...

Abstract

The invention relates to a gas combustion filter. The gas combustion filter comprises a casing and a filtering screen. The size of the casing is larger than the diameter of a gas transmission pipe. The casing is filled with the filtering screen. An elbow protruding towards the inside of the casing is further arranged at the outlet end of the casing. A plurality of gas outlets are formed in the elbow. According to the gas combustion filter, the size of the casing of the filter is far larger than the diameter of the gas transmission pipe, and accordingly the filtering area of the internally filled filtering screen is increased, and gas can be purified sufficiently; the gas outlets are distributed in the elbow so that when part of the filtering screen or the gas outlets of the filter are blocked, gas normal supply is not affected, supply of gas in a burning nozzle is sufficient, and combustion is stable.

Description

technical field [0001] The invention relates to a device for preventing clogging of gas burners, in particular to a filter for preventing clogging of gas burners used in petroleum and petrochemical industries. Background technique [0002] The gas burners used in the petrochemical industry usually use gaseous fuels composed of different components. The fuel usually contains non-gas impurities such as small particles and liquid hydrocarbons. Small particles will block the nozzle of the burner, and the liquid Hydrocarbons can cause the nozzles to coke and clog. And long-term blockage will cause the nozzle to burn out, seriously affecting the life of the burner. [0003] Existing burner filter generally all is to set up a filter suitable with gas pipeline diameter before burner nozzle, is filled with filter material in it. However, such a filter has problems such as small filter area, easy clogging of the filter screen and frequent replacement, and insufficient amount of gas ...
