Abstract
The utility model discloses a switchable filtering device at a water pump inlet and aims to solve the problem that the circulating water pump of the conventional large-sized circulating water system in the air separation industry is easy to block. The filtering device comprises an inlet valve, a circulating water pump and an outlet valve which are connected in series onto a pipeline in sequence, wherein a by-pass valve is arranged on a pipeline between the inlet valve and the circulating water pump; two filtering pipelines connected with the by-pass valve in parallel are arranged on the pipeline; filters are connected in series with the filtering pipelines; a valve is arranged on each of the front filtering pipeline and the rear filtering pipeline of each filter; a differential pressure instrument is arranged on each filtering pipeline and connected in parallel with the corresponding filter; the two filtering pipelines can be used in a switching manner. The filtering device disclosed by the utility model has the advantages that the effect of filtering bulk material is good, the frequency of cleaning a cooler in unplanned shut-down is reduced, and the two filtering pipelines are used in a switching manner, so that the filters can be switched in an on-line manner and cleaned quickly on the premise that the circulating water pump is not shut down, the reliability of the system filtering is ensured, the service life is long, and the operating and maintenance cost in later period is low.
Description
Technical field
The utility model relates to the changeable filter of a kind of unit fixed on water pump suction.
Background technology
Open cycle cooling water system between the general employing of the large-scale circulation of empty branch trade, recirculated water in fan cooling tower with cross-ventilation contact heat-exchanging, therefore water station periphery current rate is large, leaf, the water fender that blower fan tower drops and the broken larger materials such as blower fan tower packing easily enter recirculated water, circulation only depends on the sedimentation function in other filter system and pond self to complete the filtration of recirculated water at present, and these filter methods are difficult to completely above-mentioned material be peeled off from circulation, therefore these materials easily enter each compressor cooler in circulation after water circulating pump pressurization, cause compressor cooler to be stopped up and heat transfer effect decline, making compressor be forced to shut down processes, to production, make troubles, in addition, the material that enters water circulating pump directly contacts with water pump rotor, and fragile impeller may cause larger economic loss.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, provides a kind of unit fixed on water pump suction changeable filter.
The technical solution of the utility model is achieved in that the changeable filter of unit fixed on water pump suction, comprise the inlet valve, water circulating pump, the outlet valve that are connected in turn on pipeline, it is, on the pipeline between inlet valve and water circulating pump, be equipped with by-passing valve, and on pipeline with by-passing valve and be connected with filter pipeline, the filter of contacting on filter pipeline, has valve on filter pipeline before and after filter.
Further, filter pipeline is provided with differential manometer and filter and connects.
Further, filter pipeline has two, can switch standby.
The utility model is for the good filtration effect of bulk materials; for the continuous and steady operation of subsequent compression equipment provides guarantee; effectively extended oxygenerator continuous operating time; reduce non-programmed halt and cleaned cooler number of times; article two, filter pipeline the using and the reserved, guarantee can carry out the online switching of filter and Rapid Cleaning, the reliability that the system that ensured is filtered under the non-stop-machine prerequisite of water circulating pump; and long service life, later stage operation expense is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-inlet valve; 2-by-passing valve; 3-water circulating pump; 4-outlet valve; 5-filter pipeline; 6-duct type y-type filter; 7-valve; 8-differential manometer.
The specific embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, the changeable filter of unit fixed on water pump suction, comprise the inlet valve 1 being connected in turn on pipeline, by-passing valve 2, water circulating pump 3, outlet valve 4, at by-passing valve 2 and inlet valve 1, on pipeline between by-passing valve 2 and water circulating pump 3 with by-passing valve 2 and be connected with filter pipeline 5, the duct type y-type filter 6 of contacting on filter pipeline 5, duct type y-type filter 6 can be selected stainless steel, filtering accuracy 30 orders, on duct type y-type filter 6 front and back filter pipelines 5, there is valve 7, filter pipeline 5 is provided with differential manometer 8 with duct type y-type filter 6 and connects, filter pipeline 5 has two, can switch standby.
When turning off 2, one filter pipelines 5 of by-passing valve in use, observe the duct type y-type filter 6 front and back pressure reduction that differential manometer 8 shows, when pressure reduction increases, expression duct type y-type filter 6, by foreign matters from being blocked, need to be switched valve 7, is switched to another filter pipeline 5 and uses.
To exiting the filter pipeline 5 of use, unload duct type y-type filter 6, it is carried out to cleaning treatment, after cleaning, return install on filter pipeline 5 standby.
The extreme case all stopping up if there is the duct type y-type filter 6 on two filter pipelines 5, opens by-passing valve 2 and carries out emergency processing, after stopping up elimination, turns off by-passing valve 2 again, uses filter pipeline 5 to filter.
Claims (3)
1. the changeable filter of unit fixed on water pump suction, comprise the inlet valve, water circulating pump, the outlet valve that are connected in turn on pipeline, it is characterized in that: on the pipeline between inlet valve and water circulating pump, be equipped with by-passing valve, and on pipeline with by-passing valve and be connected with filter pipeline, the filter of contacting on filter pipeline, has valve on filter pipeline before and after filter.
