Description
Technical field
The utility model belongs to the filtration equipment for clarifying of the volatile liquid medium in the fields such as petrochemical industry, metallurgy, is specially adapted to indirect type gas auxiliary liquid back flush purification filtering apparatus.
Technical background
Field of petrochemical industry in the prior art for impurity content height, liquid medium that treating capacity is big, adopts that to switch the automatic backwash filtration system continuously be current main development trend.In order to make filter core reach effective regeneration, guarantee that filter core has serviceability steady in a long-term, the filter cake that generally adopts assist gas back flush mode that cartridge surface is adhered to is in the prior art removed and soiling solution is disposed to the soiling solution pond by the soiling solution feed-line, and its flow process (comprises automatic, semi-automatic and manual control) as shown in Figure 1.The assist gas back flush filtration system equipment of prior art generally is to be linked by the parallel connection of two (or many) filters, filter A and filter B rear lower in parallel joins with backwash soiling solution feed-line by automatic valve VA3, VB3 again, top in filter A and filter B joins by automatic valve VA5, VB5 and backwash assist gas pipeline, same at the pipeline that VA2, VB2 automatic valve are housed, should join with the decontaminating liquid export pipeline, the raw material liq input pipe joins with filter A and filter B respectively again by automatic valve VA1, VB1.Two filters of prior art (A and B) are to adopt switching mode to use, and when filter A carries out filter operation, the filter B standby host is stand-by.When filter A operation pressure reduction reaches setting value, provide signal by control device and switch to filter B and carry out filter operation, and filter A using gases is carried out the assist gas back flush.The assist gas back flush is operating as: filter container crestal gas injection valve is opened earlier, the backwash assist gas in the injecting gas pipeline; Backwash assist gas compression shock can be exercised the appended cake layer of filter core earlier and be become flexible, and flushbottom tank valve is opened fast then, makes backwash assist gas compressing pot liquid (soiling solution) and it is all drained into the soiling solution feed-line to enter the soiling solution pond; Filter A regeneration ending is standby.When filter B reaches setting pressure reduction, also carry out above-mentioned same backwash operation equally, filter A devotes oneself to work simultaneously.When not volatile and filtering accuracy was low when filter medium (liquid), this back-washing method was widely used; But when filter medium is volatile liquid and filtering accuracy when higher, this kind back-washing method just is not suitable for using.Because backwash assist gas and liquid medium interact, accelerated to evaporate, liquid (solution) volatilization its solute of back conjunctiva in porous filter material surface and hole, cause porous filter material hole a part so that all stop up, when serious even cause filtering technique can't continue normally to carry out; Simultaneously, also have how to handle the recovery problem in the back flush discharge liquid decontamination liquid pool,, also exist and pollute and the operating cost problem for poisonous or precious liquid.
The utility model content
The purpose of this utility model is to provide a kind of reasonable in design, the remarkable and easy to operate indirect type gas auxiliary liquid back flush purification filtering apparatus of result of use.
According to the purpose of this utility model, the solution backwash assist gas pipe that we considered does not directly insert filter container top, but the clean solution storage tank of backwash assist gas Guan Xianyu top is continuous, and discharging tube links to each other with filter top by automatic valve again under the clean then solution storage tank.Of the present utility model
Specific embodiments is:
When the composition of this device can guarantee to produce continuously, employing is no less than the system of two filters, be that filter A and filter B are connected in parallel the latter two bottom by automatic valve VA1 is housed, the pipeline of VB1 and material liquid input pipe b join, and by automatic valve VA3 is housed, the pipeline of VB3 and backwash soiling solution storage tank E join, filter A, the sidepiece of B is by being equipped with automatic valve VA2, the pipeline of VB2 and decontaminating liquid efferent duct a join, filter A, the top of B is by being equipped with automatic valve VA4, the pipeline of VB4 and emission gases efferent duct c join, it is characterized in that filter A, the top of B is also by being equipped with automatic valve VA5, the pipeline of VB5 joins with clean solution storage tank C bottom, the top of clean solution storage tank C links to each other with emission gases efferent duct c line by the pipeline that automatic valve VC3 is housed, and join by pipeline and the backwash assist gas storage tank D top that automatic valve VC1 is housed, the pipeline of the sidepiece of clean solution storage tank C by automatic valve VC2 is housed joins with the input pipe e of clean solution, and the sidepiece of gas reservoir D joins by pipeline and the backwash assist gas input pipe d that by-pass valve control V1 is housed.Import and export at filter A, B in addition one of differential pressure transmitter POT is installed between the pipeline; Filter A, B, clean solution storage tank C sidepiece one of fluid level transmitter LPT is housed respectively, clean solution storage tank C and filter A, B tank body connecting line are equipped with one of flowmeter FT.
The bottom of backwash soiling solution storage tank E joins by by-pass valve control V8 and backwash soiling solution evaporimeter F.
Compared with prior art, the utlity model has reasonable in design, the apparent person of result of use and easy to operate advantage.What this device was given prominence to advantage is that backwash assist gas pipe does not directly insert filter container top, but the clean solution storage tank of backwash assist gas Guan Xianyu top links to each other, discharging tube links to each other with filter top by automatic valve again under the clean then solution storage tank, filter medium evaporates and causes that porous filter material stops up and influences normal filtering technique when having avoided the auxiliary back flush of direct gas, guarantee effective backwash and regeneration of porous filter material, guarantee volatile liquid medium normal filtration; Simultaneously, back flush discharge liquid enters backwash soiling solution storage tank, reclaims solution with pump input evaporimeter after the accumulation some and recycles.
