Abstract
The embodiment of the utility model provides a water inflow sample filtering device of a water vapor on-line instrument, which comprises a filter shell and a filter element and is characterized by also comprising a water inflow primary valve, a water inflow blow-down valve, a water inflow secondary valve, a water outflow isolation valve and a back flush water inlet valve; the water inlet is connected with the water inlet primary valve and is sequentially connected with the water inlet secondary valve, the filter shell and the water outlet isolation valve; the water inlet is connected with a back flush water inlet valve and is connected with a water outlet isolation valve; the water inlet primary valve is sequentially connected with a water inlet blow-down valve.
Description
Technical Field
The utility model relates to an online instrument of steam water sample filter equipment that intakes.
Background
One set of primary filter equipment all is installed to current steam sampling system in the existing market before the instrument, and the filter material generally is PE sintering filter core, and filter core installs in low pressure filter, and a termination sextant hose, an end connect conventional pipe for carry out the second grade to the appearance water and filter, protection instrument electrode.
The current water vapor sampling frame filter in the existing market is one in and one out, and unqualified water sample in the initial stage can directly enter the filter device, so that the filter element of the filter is dirty and blocked, and the service life of the filter element is shortened. The existing filter device has no pollution discharge and back flushing device, and the filter element needs to be disassembled for cleaning if the filter element needs to be cleaned after being polluted and blocked.
Disclosure of Invention
The embodiment of the application provides a water sample filter equipment that intakes of online instrument of steam, installs filter equipment additional before the online instrument of steam sample for filter the instrument water sample, place aquatic impurity and cause the pollution to the instrument, reach extension instrument life's purpose.
The embodiment of the application provides a water inlet sample filtering device of a water vapor online instrument, which comprises a filter shell and a filter element, and is characterized by further comprising a water inlet primary valve, a water inlet blow-down valve, a water inlet secondary valve, a water outlet isolation valve and a back flush water inlet valve;
the water inlet is connected with the water inlet primary valve, and then is sequentially connected with the water inlet secondary valve, the filter shell and the water outlet isolation valve;
the water inlet is connected with a back flush water inlet valve and then connected with a water outlet isolation valve;
the water inlet primary valve is sequentially connected with a water inlet blow-down valve.
Furthermore, the water inlet is respectively connected with a water inlet primary valve and a back flush water inlet valve through a three-way pipe.
Furthermore, the water inlet primary valve is respectively connected with the water inlet blow-down valve and the water inlet secondary valve through a three-way pipe.
Furthermore, the backwashing water inlet valve is connected with the filter shell and the water outlet isolation valve through a three-way pipe.
The working mode is as follows:
when the unit initial stage starts steam sampling system and puts into operation, aquatic impurity is more than normal, need open the filter before the appearance blowoff valve (the blowoff valve that intakes promptly) of advancing this moment, discharges the unqualified water sample in initial stage, after the blowdown water is limpid and transparent, normally puts into operation the filter. After the filtering device operates for a period of time, the filter element is polluted and blocked, the filter element of the filter is washed by the backwashing water inlet system (the backwashing water inlet valve is opened), and impurities on the surface of the filter element are discharged to the cooling tank through the sewage discharge pipeline for recycling after being washed. The regular back washing can prolong the service life of the filter element and achieve the purposes of environmental protection and energy saving.
One or more technical solutions in the embodiments of the present application at least have one or more of the following technical effects:
the water vapor on-line instrument water inlet water sample filtering device is additionally provided with the drain valve and the backwashing pipeline, so that the service life of the filter element can be prolonged, and the on-line instrument electrode is protected. A drainage pipeline is additionally arranged on a water inlet pipeline of the filter and used for draining water samples which are unqualified in the initial stage and backwashing water samples, and a branch is additionally arranged on the water inlet pipeline and is connected to a water outlet pipeline of the filter and used for periodically backwashing the filter element, so that the purpose of prolonging the service life of the filter element is achieved.

Detailed Description
Referring to the attached drawing 1 in the specification, the embodiment of the application provides a water inflow sample filtering device for a water vapor online instrument, which comprises a filter shell 6, a filter element 7, a water inflow primary valve 1, a water inflow blowdown valve 2, a water inflow secondary valve 3, a water outflow isolation valve 4 and a backwashing water inlet valve 5. The water inlet is connected with a water inlet primary valve 1, and is sequentially connected with a water inlet secondary valve 3, a filter shell 7 and a water outlet isolation valve 4; the water inlet is connected with a back flush water inlet valve 5 and then connected with a water outlet isolation valve 4; the water inlet primary valve 1 is sequentially connected with a water inlet blow-down valve 2.
The working mode is as follows:
when the water vapor sampling system is started at the initial stage of the unit and put into operation, impurities in water are excessive, the blowoff valve before the filter is fed with a sample (namely, the water inlet primary valve 1 and the water inlet blowoff valve 2 are used for discharging the water sample, the unqualified water sample at the initial stage is discharged, and the filter is put into operation normally after the discharged water is clear and transparent. After the filtering device operates for a period of time, the filter element is polluted and blocked, and at the moment, the filter element is washed by a backwashing water inlet system (namely, a backwashing water inlet valve 5, a filter shell 6, a filter element 7, a water inlet secondary valve 3 and a water inlet blow-down valve 2), impurities on the surface of the filter element are washed and then discharged to a cooling pool through a blow-down pipeline for recycling. The regular back washing can prolong the service life of the filter element and achieve the purposes of environmental protection and energy saving.
