Abstract
The invention provides a negative pressure sewage discharge device of a compressor, and relates to the field of compressor devices. The negative pressure sewage discharge device comprises a sewage discharge collection tank, a front liquid separator and a first-stage cylinder base. The sewage discharge opening of the front liquid separator is connected with the sewage discharge collection tank through a pipeline A. The sewage discharge opening of the first-stage cylinder base is connected with the sewage discharge collection tank through a pipeline E. The sewage discharge collection tank is communicated with the front liquid separator through a pipeline B, connected with the sewage discharge opening with the highest pressure in a compressor unit through a pipeline C, and connected with other sewage discharge openings in the compressor unit through pipelines D. The sewage discharge collection tank is connected with the main sewage discharge opening through a pipeline F. Stop valves are arranged on the pipelines respectively. The negative pressure sewage discharge device solves the problems that when the gas pressure inside the front liquid separator and the first-stage cylinder base is lower than the atmosphere pressure, sewage separated out of the front liquid separator and sewage in the gas inlet side of the first-stage cylinder base can not be discharged, and eliminates potential safety hazards in the running process of the compressor.
Description
Technical field
The present invention relates to compressor apparatus field, particularly relate 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.
Summary of the invention
The object of the present invention 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 by this invention 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 invention has the beneficial effects as follows:
Compressor negative pressure drainage device provided by the invention, 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.
