Description
Technical field
The utility model relates to compressor apparatus field, particularly relates to a kind of compressor negative pressure drainage device.
Background technique
Compressor is a kind of driven fluid machinery low-pressure gas being promoted to pressurized gas.In order to when preventing compressor operating, gas contains a large amount of liquid waters, liquid hit phenomenon is caused to damage compressor, usually liquid/gas separator before being provided with in air inlet pipeline system, liquid water contained in gas is separated by separator, then emitted by blowdown valve, to ensure safety during compressor operating.But often in many situations, compressor suction pressure, lower than atmospheric pressure, to cause in one-level air inlet pipeline system (containing front liquid/gas separator and first-stage cylinder seat air inlet side sewage draining exit) pressure lower than atmospheric pressure; In addition, if suction pressure is in the state of barometric pressure or micro positive pressure, when compressor bank runs air-breathing, the pressure of one-level air inlet pipeline system and first-stage cylinder seat air inlet side also may be caused lower than barometric pressure; Thus the soiling solution of the soiling solution causing front liquid/gas separator to be separated and first-stage cylinder seat air inlet side row does not go out, and brings hidden danger to the operation of compressor.
Model utility content
The purpose of this utility model is to provide a kind of compressor negative pressure drainage device, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of compressor negative pressure drainage device, it is characterized in that: comprise blowdown and gather tank, front liquid/gas separator and one-level cylinder block, the sewage draining exit of described front liquid/gas separator gathers tank by pipeline A with blowdown and is connected, the sewage draining exit of described one-level cylinder block gathers tank by pipeline E with blowdown and is connected, described blowdown is gathered tank and is also communicated with front liquid/gas separator by pipeline B, also be connected by the sewage draining exit that pipeline C is the highest with pressure in Compressor Group, also be connected with other sewage draining exit in Compressor Group by pipeline D, described blowdown gathers tank and connects total sewage draining exit by pipeline F, each pipeline is equipped with stop valve.
Described pipeline D comprises many independently pipelines, and the sewage draining exit of in Compressor Group is all gathered tank with blowdown and is connected by every bar pipeline.
Each pipeline blowdown successively during blowdown; First blowdown is carried out to front liquid/gas separator, opens the stop valve of pipeline A and pipeline B, close other valve, be connected because pipeline B and blowdown gather tank, before liquid/gas separator and blowdown gather the pressure balance of tank inside; For ensureing that liquid dirt drains, blowdown should be made to gather tank and be in the lowest part putting dirty device, therefore soiling solution can gather tank by pipeline A inflow blowdown smoothly; Judge whether soiling solution drains by the level meter on front liquid/gas separator, if drain, close the valve on pipeline A, open the valve on pipeline E, in like manner can get rid of cylinder block air inlet side soiling solution smoothly; Close the valve on pipeline B, E, according to the order from low pressure to high pressure, open all the other each pipeline valves successively and carry out blowdown.
Each pipeline is provided with the device judging that soiling solution drains, as visible observation pipe or flow detector, flows into the soiling solution gathered in tank and can focus on discharge according to the pipeline power of compressor bank high pressure stage to soiling solution.
The beneficial effects of the utility model are:
The compressor negative pressure drainage device that the utility model provides, solve the gas pressure of front liquid/gas separator and first-stage cylinder seat inside lower than atmospheric pressure, and the problem of not going out arranged by the soiling solution of the soiling solution causing front liquid/gas separator to be separated and first-stage cylinder seat air inlet side, eliminate the potential safety hazard in compressor operating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
