Abstract
The utility model belongs to the technical field of fuel gas convying and distribution equipment, a gas filter backwash cleaning device is disclosed. Its main technical characteristics does: casing including having the inlet end, giving vent to anger and hold is provided with the filter core in, the end of giving vent to anger of casing is connected with external air supply through high -pressure pipeline, and high -pressure pipeline is provided with high pressure valve, and the bottom of casing is provided with the blowoff valve. When this gas filter backwash cleaning device washd the filter core, the valve with pipeline around the filter housing turn -offed earlier, laid down the interior residual pressure of casing, fastened the bleed valve and formed airtightly. Then open the high pressure valve of high -pressure pipeline, the gas in the substandard coherent source of nitrogen cylinder gets into the casing through high -pressure pipeline, carries out the opposite direction to the filter core and sweeps. After pouring into certain high -pressure gas into, open the blowoff valve, will erode attached to filter element surface's impurity, filth, discharge through the blowoff valve. The efficiency of the operating mass with rated load of filter has alleviateed intensity of labour, work is improved.
Description
Technical field
The utility model belongs to gas transmission and distribution equipment technical field, particularly relates to a kind of gas filter backwash clearing apparatus.
Background technology
Gas filter uses a period of time just to need to clean filter core, and general majority all adopts and taken apart by blind flange, then filter core is pulled down to take out cleans.After knowing dirt, then original position is installed: fix filter core, clean seal face, add flange gasket, upper flange lid screws, gas testing is close ... Deng multiple working procedure, very loaded down with trivial details, waste time and energy.
Utility model content
It is simple that technical problem to be solved in the utility model is just to provide a kind of structure, gas filter backwash clearing apparatus easy to use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the housing with inlet end, outlet side, filter core is provided with in housing, the outlet side of described housing is connected with external gas source by pressure duct, pressure duct is provided with high pressure valve, and the bottom of housing is provided with blowoff valve.
A kind of gas filter backwash clearing apparatus provided by the utility model, when gas filter needs to clean filter core, first turns off the valve of pipeline before and after filter housings inlet end, outlet side, lays down overbottom pressure in housing, fasten vent valve and formed airtight.Then open the high pressure valve of pressure duct, the gas of the external gas sources such as nitrogen cylinder enters housing by pressure duct, carries out opposite direction purge filter core.After injecting certain gases at high pressure, open blowoff valve, the impurity, the dirt that are attached to cartridge surface are washed away, is discharged by blowoff valve.In operation, blowoff valve should be opened instantaneously, closes immediately after discharging certain impurity.After continuous so intermittent blowdown several times, on filter core, impurity will thoroughly be removed, thus improves the work quality of filter, alleviates labour intensity, improves operating efficiency.Want 1-2 individual hour with conventional method cleaning, and adopt blowback to clean a few minutes can to complete.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gas filter backwash of the utility model clearing apparatus.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of a kind of gas filter backwash of the utility model clearing apparatus and operation principle are described in further details.
As shown in Figure 1, a kind of gas filter backwash of the utility model clearing apparatus comprises housing 1, housing 1 is with inlet end 2, outlet side 3, filter core 4 is provided with in housing 1, the outlet side 3 of housing 1 is connected with external gas source 6 by pressure duct 5, pressure duct 5 is provided with high pressure valve 7, and the bottom of housing 1 is provided with blowoff valve 8.
A kind of gas filter backwash clearing apparatus provided by the utility model, when gas filter needs to clean filter core, first turns off the valve of pipeline before and after filter housings 1 inlet end 2, outlet side 3, lays down overbottom pressure in housing 1, fasten vent valve and formed airtight.Then open the high pressure valve 7 of pressure duct 5, the gas of the external gas sources such as nitrogen cylinder 6 enters housing 1 by pressure duct 5, carries out opposite direction purge filter core 4.After injecting certain gases at high pressure, open blowoff valve 8, the impurity, the dirt that are attached to filter core 4 surface are washed away, is discharged by blowoff valve 8.In operation, blowoff valve 8 should be opened instantaneously, closes immediately after discharging certain impurity.After continuous so intermittent blowdown several times, on filter core 4, impurity will thoroughly be removed, thus improves the work quality of filter, alleviates labour intensity, improves operating efficiency.
The utility model is not limited only to above-mentioned form, but no matter is adopt which kind of form, as long as structure is identical with the utility model, all falls into protection domain of the present utility model.
