Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1 to 3, in embodiment 1 of the present invention, a medical air compression air storage tank pollution discharge apparatus includes an air storage tank 1, a temporary storage pipe 4, a pressure balancing mechanism 9, a liquid level sensor 3, a sewage tank 10, and an oil-water separator 15; the bottom of the gas storage tank 1 is fixedly connected with a temporary storage pipe 4, and the temporary storage pipe 4 is connected with a pressure balance mechanism 9; the pressure balancing mechanism 9 comprises a sewage tank 10, a draft tube 7 and a gas pipe 20; the one end that the pipe 4 kept away from the gas holder 1 of keeping in passes through honeycomb duct 7 and connects sewage case 10, the rigid coupling has gas pipe 20 on the sewage case 10, gas pipe 20 connects the lateral wall of gas holder 1, the rigid coupling has one-level solenoid valve 8 on the honeycomb duct 7, the rigid coupling has second grade solenoid valve 19 on the gas pipe 20.

This device utilizes pipe 4 of keeping in to store filths such as water oil that gas holder 1 gathered the production, because the sectional area of pipe 4 of keeping in is less, the volatilization of sewage also receives certain restriction. The sewage stays in the temporary storage pipe 4 under the condition of no sewage discharge, and flows into the sewage tank 10 through the draft tube 7 in the sewage discharge process.

The pressure balancing mechanism 9 of the device can realize the pressure leveling in the sewage discharge process. When the liquid level sensor 3 sends a signal to discharge sewage, the signal processor 2 opens the secondary hydraulic valve first to balance the air pressure in the sewage tank 10 and the air pressure in the air storage tank 1, and then opens the primary electromagnetic valve 8 to make the sewage in the temporary storage pipe 4 enter the sewage tank 10. After the drainage is finished, the first-stage electromagnetic valve 8 and the second-stage electromagnetic valve 19 are closed, the sewage tank 10 is isolated from the air storage tank 1, and the sewage can be subjected to subsequent treatment.

Because pressure balance under the blowdown state, consequently can not appear sewage and splash during the blowdown, also can not appear huge noise and go, and owing to there is not the pressure differential, the problem that volatilizees rapidly and get back to in the air can not appear in sewage yet. Because the problem of excessive leakage of high-pressure gas caused by opening the primary electromagnetic valve 8 for a long time does not need to be considered, the device knows that the gas consumed by sewage disposal at each time is the gas occupied by the space of the sewage tank 10, and therefore the device can properly prolong the sewage disposal time so as to ensure thorough sewage disposal.
