Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of precoating, from process formula particulate filter arrangement, comprises the cylindrical shell 1 be vertically supported on support body.Cylindrical shell adopts the tube structure on existing particulate filter arrangement, concrete, and the main body of cylindrical shell is cylinder-like structure, and the upper end of cylindrical shell is that circular arc binds, and form cylinder top, the lower end part of cylindrical shell is conical head structure, is formed at the bottom of cylinder.Be provided with evacuation port 110 at the top of cylindrical shell, the bottom of cylindrical shell is provided with waste discharge mouth 120.Evacuation port and waste discharge mouth, under this particle device is in different duties, all can be opened or close.Be provided with in cylindrical shell and connect by drain line 220 filter assemblies 2 formed by multiple filter core 210, drain line extends to cylindrical shell outside.Concrete, each filter core is made up of the filter cloth of filter cylinder and parcel filter cylinder, and the drain side of each filter cylinder is all communicated with drain line, makes multiple filter core be formed and connect like this.Position near bottom on the sidewall of cylindrical shell is provided with the feed liquor adapter A3 extend in cylindrical shell.Outside cylindrical shell, be provided with bypass line A4, bypass line A is provided with circulating pump A5, the two ends of bypass line A are connected with feed liquor adapter A and drain line respectively by three-way connection, form precoating peripheral passage.On bypass line A, the outer end position of feed liquor adapter A and the outer end position of drain line be all provided with valve.Position near bottom on the sidewall of cylindrical shell is also provided with the fluid adapter 6 extend in cylindrical shell, the feed liquor adapter B7 extend in cylindrical shell is provided with at the top of cylindrical shell, bypass line B8 is also provided with outward at cylindrical shell, bypass line B is provided with circulating pump B9 and valve, the outer end that the two ends of bypass line B are taken over outer end and the fluid of feed liquor adapter B is respectively connected, and forms discharge opeing peripheral passage.Position near top in cylindrical shell is provided with the spray equipment 10 be connected with the inner of feed liquor adapter B.Be provided with intake interface 130 at the top of cylindrical shell, intake interface is connected with the air inlet pipeline 11 be arranged on outside cylindrical shell, and air inlet pipeline is connected with extraneous nitrogen feeder, forms gas charging system, air inlet pipeline is provided with valve.
In said structure, at cylindrical shell, the liquid level gauge 12 that can detect liquid level in cylindrical shell is also installed outward, concrete, liquid level gauge is arranged on the wall outer surface of cylindrical shell, the inner chamber of itself and cylindrical shell forms connected state, discharge at pre-coating solution like this in the process of cylindrical shell, the surplus of pre-coating solution in cylindrical shell just can be checked easily by liquid level gauge, when the surplus of pre-coating solution reaches lower limit position, circulating pump B can be closed in time, thus discharge opeing peripheral passage is cut off, and then avoid liquid and blot and the damage causing circulating pump B, it also avoid and damage is to a certain degree caused to the cake layer that filter core coats in advance.
In said structure, feed liquor adapter A is positioned at the part that the part of cylindrical shell and fluid adapter be positioned at cylindrical shell and is all preferably downward elbow structure.Effectively can avoid the deposition of the precoating material in pre-coating solution like this.
This precoating needs the precoating first completing cake layer from process formula particulate filter arrangement before to crude oil or natural gas filtering, and detailed process is:
First the valve of feed liquor adapter A outer end position is opened, make other valves on this particulate filter arrangement be in simultaneously and close shape body, the pre-coating solution containing precoating material is made to enter in cylindrical shell from feed liquor adapter A like this, be full of after cylindrical shell until pre-coating solution, close the valve of feed liquor adapter A outer end position and the evacuation port at cylindrical shell top, then the valve on bypass line A and circulating pump A is opened, the pre-coating solution entered in cylindrical shell is circulated in the precoating peripheral passage connected and composed by cylindrical shell and bypass line A, in the process of pre-coating solution circulation, precoating material is attached to the outer of filter core gradually and wraps up on filter cloth, after the precoating of certain hour, filter cloth forms the uniform cake layer be made up of precoating material, then the valve on circulating pump A and bypass line A is closed, and ON cycle pump B, the valve of the valve on bypass line B and drain line outer end position, like this, pre-coating solution in cylindrical shell is under the effect of circulating pump B, be inhaled in bypass line B by the bottom of cylindrical shell, then enter in spray equipment, sprayed away uniformly through the top of mouth spray in cylindrical shell of spray equipment, form a stable circulation, valve afterwards on unlatching air inlet pipeline gradually, nitrogen is made to enter in cylindrical shell, there is imbalance state in the stable circulation before under the effect of nitrogen, pre-coating solution moves to one end that pressure is low gradually, the cake layer of such pre-coating solution gradually by being made up of precoating material, filter layer of cloth, enter in filter cylinder, and be discharged to outside cylindrical shell by drain line, thus achieve the Self-discharged process after pre-coating solution precoating.
After pre-coating solution is discharged in cylindrical shell, close the valve on circulating pump B and bypass line B, and particles at rest filter one end time, make the precoating material mummification be attached on filter cloth, then, crude oil containing granule foreign or natural gas are imported in cylindrical shell from above-mentioned feed liquor adapter A, along with constantly carrying out of operation, fine particle impurity can be attached on the cake layer that is made up of precoating material, and oil after filtering or natural gas are discharged by above-mentioned drain line, thus achieve the filtration of crude oil or natural gas.When being adsorbed on the granule foreign on cake layer and being more, liquid or gas circulation can be caused not freely, so just there will be obvious liquid inlet volume and reduce or the larger phenomenon of inlet outlet pressure differential.In this case, just need the filtration stopping crude oil or natural gas, ventilated, utilize air pressure that filter layer of cloth is expanded by drain line in cylindrical shell, the cake layer be attached to like this on filter cloth is just separated gradually, and is discharged by the waste discharge mouth of cylinder body bottom.
