Description
Technical Field
The utility model belongs to the technical field of nuclear power engineering, concretely relates to anti-device that sweeps of joint control oil-free screw air compressor host computer.
Background
The design redundancy of the joint control oil-free screw type air compressor is high, and two-purpose four-standby or three-purpose three-standby is generally adopted. Spare air compressor machine is owing to do not operate for a long time, and the host computer lacks the dampproofing measure in humid environment, appears spare part corrosion easily, rotor coating adheres adhesion scheduling problem. When the pressure of a compressed air pipe network is low, serious faults such as vibration, noise and even rotor burning can occur after the standby air compressor is loaded and started, and the main machine of the screw air compressor can generate huge maintenance cost, so that long-term adverse effects can be generated on the redundancy of a compressed air system. In order to improve the reliability of the overall equipment of the joint control type oil-free screw air compressor unit, the influence of the environment on the main machine of the air compressor during the shutdown of the standby oil-free screw air compressor is necessary to be relieved through innovative design.
Disclosure of Invention
An object of the utility model is to provide a device is swept in anti-reflection of joint control oil-free screw air compressor host computer solves the technical problem that the host computer receives the environmental impact easy to break down during oil-free screw air compressor unit shut down reserve.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
a host back flushing device of a linkage control oil-free screw type air compressor comprises a main compressed air pipe buffer tank, an isolation valve, a pressure reducing valve, an electromagnetic valve, a secondary host, a primary host, an air inlet butterfly valve, a check valve, an emptying pipeline and an emptying silencer; the pressure-air main pipe buffer tank, the isolation valve, the pressure reducing valve and the electromagnetic valve are sequentially connected through a pipeline, and the downstream is divided into two branches which are respectively connected with the secondary host and the primary host; the outlet of the primary main machine is connected with an air inlet butterfly valve, the outlet of the air inlet butterfly valve and the outlet pipeline of the secondary main machine are connected with an emptying silencer after being converged, and the check valve is connected with the outlet of the secondary main machine.
A pipeline is led out from a buffer tank of the compressed air main pipe and used as back-flushing gas, the gas enters a secondary host and a primary host to be internally purged under the control of an electromagnetic valve after being decompressed by an isolation valve and a decompression valve, the exhausted waste gas enters an emptying pipeline, and the purged waste gas is collected behind an emptying silencer through an air inlet butterfly valve and the emptying pipeline and then is exhausted into the environment.
The utility model discloses the beneficial effect who gains does:
the main engine of the joint control type oil-free screw air compressor does not run in the standby period, the clean compressed air introduced from the main pipe network sweeps the rotor inside the main engine discontinuously, the humid air and impurities of precise parts are discharged, and the abrasion/burning-out fault of the main engine of the oil-free screw air compressor is effectively avoided.

the pressure-air main pipe buffer tank 1, the isolation valve 2, the pressure reducing valve 3 and the electromagnetic valve 4 are connected in sequence through pipelines, and the downstream is divided into two branches which are respectively connected into a secondary host 5 and a primary host 6. The outlet of the first-level main engine 6 is connected with an air inlet butterfly valve 7, and the outlet of the air inlet butterfly valve 7 is connected with an emptying silencer 10 after being converged with an outlet pipeline of the second-level main engine 5, namely an emptying pipeline 9. The check valve 8 is connected to the outlet of the secondary main unit 5.
A pipeline is led out from the pressure-air main pipe buffer tank 1 and used as back-flushing gas, the pressure is reduced through the isolation valve 2 and the pressure reducing valve 3, the gas enters the secondary main machine 5 and the primary main machine 6 to be internally purged under the control of the electromagnetic valve 4, and the exhausted waste gas enters the air release pipeline 9. The purged waste gas is collected in a vent silencer 10 through an air inlet butterfly valve 7 and a vent pipeline 9 and then is discharged into the environment.
