Detailed description of the invention:
Structure of the present utility model and embodiment is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, the utility model high-pressure natural gas desander is made up of tank body sealing nut 2, cartridge filter 3, desanding tank body 4, base 6, sand removing hole 7, right angle four-way 15.Tank body sealing nut 2 and desanding tank body 4 are threaded connection, and desanding tank body 4 and base 6 are by Flange joint, and base 6 and sand removing hole 7 are by Flange joint, and right angle four-way 15 is connected with external pipe by flange and screw thread.
During utility model works, two high pressure desander devices can be arranged in the framework fixed, and be connected with each valve by exterior line, can use two kinds of different work stages.
One, the non-desanding stage
When the air-flow sand content penetrated from gas well lower without the need to desanding time, can by close corresponding valve, open intervening vaive, make air-flow directly flow to downstream by pipeline.
Two, the single-stage desanding stage
When the air-flow sand content penetrated from gas well is more need desanding time, two natural gas desanders are together in parallel, normal operation is used alternatingly, suppose the desander work first using left side, the valve closing relevant to right side desander by desander intervening vaive, open corresponding valve on the desander of left side simultaneously, left side desander is kept to be in unimpeded state, air inlet port valve open, treat that the natural gas of desanding tangentially injects desanding tank body 4 inner chamber by the air inlet port 11 of desander, internal gas realizes the disengaging of solid sand grains under the filtration of cartridge filter 3.Natural gas after desanding upwards enters desander tank body 4 epicoele through filtering inside, enters external pipe by the gas outlet 9 of desanding tank body 4 epicoele.The solid phase particles such as the sand grains in natural gas and part water and oil sink to entering desanding tank body 4 cavity of resorption, when the height of the sand heap in desanding tank body 4 cavity of resorption reach a certain height value, need to carry out sediment outflow operation.When left side desander desanding effect declines, right side desander work need be changed, open that right side desander goes out, imported valve successively.At the end of desanding, close valve on desander import and export pipeline successively.After desanding terminates a period of time, open lower relief valve 5, upper relief valve 8 successively, observe pressure meter 12, pressure sensor 13, registration is until be zero.
