Description
Technical field
The present invention relates to a kind of compressor filtration system, especially relate to and a kind ofly can change the carbon monoxide compressor filtration system of filter by on-bne repair.
Background technique
At present, carbon monoxide compressor mainly in order to carbon monoxide pressurization designed by compressor, in order to the purity of the high pressure carbon monoxide product of carbon monoxide after compressor pressurizes, usually can increase a carbon monoxide filter.But carbon monoxide is by compressor process, cylinder and pressurized gas can be there are there is friction thus produce carbon dust, this will make pressure reduction before and after carbon monoxide filter gradually raise, thus the filter core in carbon monoxide filter is blocked, carbon monoxide product cannot be normal through, causes stopping supplying client.At this time just need to stop carbon monoxide compressor to change the filter core in carbon monoxide filter.
Related documents also discloses many switch filtering devices in parallel has good guarantee for the stable persistency in production process, but be mainly still applied to if water, ammonia, oil product, hydro carbons are main, because the possibility of its impurity existed of this kind of article is present in fluid and gas itself.And the machine body cylinder of carbon monoxide compressor and CO (carbon monoxide converter) gas rub, the filtration of the large particle carbon dust produced is not suitable for structure recited above.
Summary of the invention
Object of the present invention is exactly to overcome the defect and provide a kind of using scope wide, safe and reliable can change the carbon monoxide compressor filtration system of filter by on-bne repair that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind ofly can change the carbon monoxide compressor filtration system of filter by on-bne repair, the outlet of carbon monoxide compressor connects pressurized gas pipeline, this pressurized gas pipeline is provided with front filter, described pressurized gas pipeline is also provided with front filter bypass line, after-filter and after-filter bypass line, described after-filter and after-filter bypass line are located at the downstream of front filter, the import and export two ends of described front filter are provided with stop valve, and the import and export two ends of described after-filter are provided with stop valve; Described front filter bypass line and after-filter bypass line are equipped with stop valve.
The import and export of described front filter bypass line are positioned at the outside of the stop valve at the import and export two ends of front filter;
The import and export of described after-filter bypass line are positioned at the outside of the stop valve at the import and export two ends of after-filter.
The both sides that front filter imports and exports the stop valve at two ends are all provided with blind plate; The both sides that the stop valve at two ends imported and exported by after-filter are all provided with blind plate.
Described front filter and the top of after-filter are equipped with pressure relief valve.
Described front filter and after-filter all adopt model to be the filter of bohr MCC1401E500H13, and design pressure is 2.0MPA, design temperature is 80 DEG C, weight is 440KG.
Described front filter is identical with the internal structure of after-filter, primarily of suction flange head, outlet(discharge) flange head, filter body, filter core, blind flange, leads pouring and fastening piece composition.
Carbon monoxide is 1.6MPA in the ducted operational condition of pressurized gas, 40 DEG C, and the design condition of pressurized gas pipeline is 1.85MPA, 40 DEG C.
Working principle of the present invention is:
In the present invention, after-filter is connected on front filter downstream, first front filter is used during use, stop valve now on front filter bypass line is closed, the stop valve that two ends imported and exported by after-filter is closed, compression carbon monoxide is after front filter, then through this flow process of after-filter bypass line, original production status can normally be kept.
When front filter pressure reduction is higher than 0.75bar, illustrate that the filter core of front filter has blocking, when needing to keep in repair front filter, the stop valve directly front filter can being imported and exported two ends is closed, and opens the stop valve on front filter bypass line, opens the stop valve that two ends imported and exported by after-filter, and the stop valve of closing on after-filter bypass line, front filter can be unloaded like this and carry out more renew cartridge or maintenance, play remaining normal and produce, again the object of more renew cartridge.
After front filter maintenance process, normal mode can be switched to, both front filter was arranged on pressurized gas pipeline, and opened the stop valve that front filter imports and exports two ends, the stop valve on front filter bypass line is closed, the stop valve that two ends imported and exported by after-filter is opened, close the stop valve on after-filter bypass line, compression carbon monoxide through front filter, by the pattern of filter later, to prevent after-filter after pressure reduction raises, directly affect product pressure.
Compared with prior art, the present invention has the following advantages and beneficial effect:
One, using scope is wide: because similar carbon monoxide compressor can exist the problem of cylinder similar equally and gas friction generation carbon dust, so system of the present invention can be applied to the compressor of same medium.
Two, safe and reliable: because newly-increased after-filter is that be through gas pressure testing for pressure-bearing aspect, two filters can bear the too high danger of gas pressure according to front filter design.In addition for system decompression, because pressure relief valve is all equipped with in the top of front filter and after-filter, by the direct pressure release of top hand valve.
Three, long-term benefit: due to this carbon monoxide compressor directly faced by be Product supply client, therefore stop supplying to be exactly direct economic loss for enterprise, and system of the present invention can repair or replace filter core to filter by direct-on-line, the normal operation of production can not be affected.
Four, maintenance is convenient: there is blind plate the stop valve both sides importing and exporting two ends due to front filter or after-filter, can excise filter fast, and with blind plate isolation, there is not the problem of keeping in repair and leaking early stage.
