Fig. 1 is a schematic structural diagram of the present invention.
The reference numbers in the figures are as follows: 1. distilled water input pipe, 2 distilled water tank, 3Y-shaped pneumatic control angle seat valve, 4 liquid level sensor a, 5, pipe a, 6, three-way pneumatic control angle seat valve, 61, valve port a, 62, valve port b, 63, valve port c, 7, one-way check valve, 8, liquid level sensor b, 9, drainage pump tank, 10 and pipe b.
Detailed Description
The present invention will be further explained with reference to fig. 1:
the air pressure drainage device applied to the industrial MVR evaporator comprises a pipe a5 connected with a drainage pump tank 9, wherein a liquid level sensor a4 is arranged on the drainage pump tank 9, the bottom end of the pipe a5 extends to the bottom in the drainage pump tank 9, the other end of the pipe a5 is connected with a pipe b10 through a one-way check valve 7, a three-way type air control angle seat valve 6 is arranged at the top of the drainage pump tank 9, the three-way type air control angle seat valve 6 comprises a valve port a61 used for being connected with the drainage pump tank 9, the valve port a61 is connected with the drainage pump tank 9 through a pipe c, a valve port b62 used for being connected with a compressed air source and a valve port c63 used for being communicated with the atmosphere, the drainage pump tank 9 is connected with a distilled water tank 2 through a pipe d, a distilled water input pipe 1 and a liquid level sensor b8 are arranged on the distilled water tank 2, and a Y.
Distilled water flows to the distilled water tank 2 from the distilled water input pipe 1, when the liquid level reaches a certain height, the liquid level sensor b8 is triggered, the system receives a signal and commands the Y-shaped pneumatic control angle seat valve 3 to be opened, at the moment, the valve port a61 of the three-way pneumatic control angle seat valve 6 is communicated with the valve port c63, (the valve port c63 is communicated with the atmosphere); the distilled water flows to the drain pump tank 9 due to the pressure difference. According to the internal pressure of the distilled water tank 2 and the height of the liquid level sensor b8, the opening time of the Y-shaped pneumatic control angle seat valve 3 is set, the fact that the height of the distilled water in the drainage pump tank 9 is higher than that of the liquid level sensor a4 is guaranteed, the Y-shaped pneumatic control angle seat valve 3 is closed after being opened for a certain time, after the Y-shaped pneumatic control angle seat valve 3 is closed, a valve port a61 and a valve port b62 of the three-way pneumatic control angle seat valve 6 are communicated, a valve port c63 is closed, compressed air begins to be injected into the system through a valve port b62 of the three-way pneumatic control angle seat valve 6, the distilled water in the drainage pump tank 9 is discharged through a pipe a5 by means of air pressure, and when the liquid level of the distilled water in the drainage pump tank 9 is lower than that of the liquid level sensor a. To prevent the distilled water from flowing backward into the drain pump tank 9 when the distilled water in the pipe 10 is drained, a one-way check valve 7 is added between the pipe b10 and the pipe a5 to prevent the distilled water from flowing backward.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
