Description
Technical field
It the utility model is related to a kind of ultrafiltration air purge gas source pipe device, particularly a kind of heat power plant boiler make-up water
Ultrafiltration air purge gas source pipe device, belong to power plant boiler make-up water water making device technical field.
Background technology
Following construction of fire and electricity is overcritical by mainly development high efficiency high parameter（SC）And ultra supercritical（USC）Thermal motor
Group, they have widely been studied and applied in developed country.But supercritical unit is high to boiler feedwater water quality requirement,
Therefore boiler feedwater membrane technology will turn into development trend.Ultrafiltration membrance filter precision is far above conventional filter, to suspending
Particulate matter, colloid, microorganism, bacterium, viral removal rate are remarkably improved the permeant flux of follow-up film process, saved up to 100%
Subsequent film dosage, efficiency and stability that follow-up cleaning frequency membrane improves follow-up film process is greatly lowered.Ultrafiltration belongs to filter membrane
Filtering technique, is a kind of pressure-actuated filtering technique, and hydraulic pressure is entered into component with pump, poor by the mould of filter membrane（TMP）Intake
To filtering, impurities in water is removed by filter membrane, and impurity is left in influent side, when by except impurity concentration uprise when, in filter membrane table
Impurity deposit layers caused by face, sedimentary can change its filtering property and required filter pressure, so as to cause ultrafiltration pressure difference liter
Higher position must carry out conventional backwash.Air purge is a most important step in ultrafiltration conventional backwash link, air purge main wash milipore filter
The impurity deposit layers thing that the impurity deposit layers thing left, particularly Chemical cleaning are also difficult to clean off.As air purge dynamics not enough if surpass
Filter membrane pressure difference can not just be down to runtime value.One end air inlet that the gas source pipe design of ultrafiltration at present uses, causes front and rear terminal membrane air inlet
Amount differs greatly, and as long-time air purge dynamics is inadequate, rear terminal membrane impurity deposit layers thing can cumulative blocking film wire.
Utility model content
The technical problems to be solved in the utility model is：A kind of heat power plant boiler make-up water ultrafiltration air purge gas source pipe
Device, terminal membrane air inflow differs greatly problem before and after solving ultrafiltration, greatly prolongs milipore filter run time, reduces boiler feedwater
Workshop operation cost.
The technical solution of the utility model is：A kind of heat power plant boiler make-up water ultrafiltration air purge gas source pipe device,
Including milipore filter, source of the gas branch pipe, the first source of the gas supervisor, the second source of the gas supervisor, source of the gas drier and valve, described milipore filter and
Source of the gas branch pipe connects；Source of the gas branch pipe and the supervisor's connection of the first source of the gas；Second source of the gas is responsible for one end and position in the first source of the gas supervisor
Put connection.
Described milipore filter at least two.
Described the first source of the gas supervisor is arranged between two milipore filters.
Described source of the gas branch pipe is stainless steel.
Described the first source of the gas supervisor is stainless steel.
Described the second source of the gas supervisor is stainless steel.
Described valve is separately positioned on source of the gas branch pipe, the first source of the gas supervisor and the second source of the gas supervisor, described valve
For stainless steel.
Be compared with the prior art, using the technical solution of the utility model by the gas source pipe of ultrafiltration from one end air inlet makes into
Portion's air inlet, can quickly solve front and rear terminal membrane air inflow and differ greatly problem, and be easy to transform, improvement cost is relatively low.
Brief description of the drawings
Fig. 1 is the utility model structure drawing of device；
In figure：1st, milipore filter, 2, source of the gas branch pipe, the 3, first source of the gas supervisor, the 4, second source of the gas supervisor, 5, valve.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings
Shown in Fig. 1, a kind of heat power plant boiler make-up water ultrafiltration air purge gas source pipe device, including milipore filter 1, source of the gas
Branch pipe 2, the first source of the gas are responsible for the 3, second source of the gas supervisor 4 and valve 5, milipore filter 1 and source of the gas branch pipe 2 connect；Source of the gas branch pipe 2 and
The connection of one source of the gas supervisor 3；Second source of the gas is responsible for 4 one end and is connected with the first source of the gas 3 medium positions of supervisor.
Further milipore filter 1 at least two, inside the apparatus structure of multiple milipore filters 1, the reality of the technical program
Shi Caineng plays substantial role.
Further first source of the gas supervisor 3 is arranged between two milipore filters, and it is poor quickly to solve front and rear terminal membrane air inflow
Different larger problem.
Further source of the gas branch pipe 2 is stainless steel, and stainless steel is not easy to get rusty, and reliability is high, will not be because of pipe
Road internal rust causes gas source pipe to block.
Further first source of the gas supervisor 3 is stainless steel, and stainless steel is not easy to get rusty, and reliability is high, Bu Huiyin
Gas source pipe is caused to block for pipeline internal rust.
Further second source of the gas supervisor 4 is stainless steel, and stainless steel is not easy to get rusty, and reliability is high, Bu Huiyin
Gas source pipe is caused to block for pipeline internal rust.
Further valve 5 is separately positioned on source of the gas branch pipe 2, the first source of the gas supervisor 3 and the second source of the gas supervisor 4, is set
Valve 5 is easy to device independently to overhaul, and will not cause to fill a device stoppage in transit because single assembly overhauls
Further valve 5 is stainless steel, and stainless steel is not easy to get rusty, and reliability is high, will not be because of in pipeline
Portion, which gets rusty, causes gas source pipe to block.
It can be tested after the installation that each equipment and original paper are carried out according to the technical solution of the utility model connects.
