[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-Figure 3As shown, the present application proposes an ammonia leakage monitoring and safety discharge device, which is installed at one end of the lubricating oil discharge and mainly consists of a tank, an ammonia monitoring device, a pipe joint, several pipes and an electromagnetic switch valve, etc.:

[0024] The tank body 1 is divided into two compartments by a partition, namely a static compartment and a storage compartment, and a gap is reserved above and below the partition to connect the two compartments;

[0025] The tank body 1 is provided with a first connection seat 12 above the static chamber for connecting the oil inlet pipe 2, and a second connection seat 13 is provided for connecting the nitrogen pipe 3, and a first electromagnetic switch valve 31 is installed on the nitrogen pipe 3;

[0026] The tank body 1 is provided with a third seat 14 at a position of 75% height (optional) on the side of the static chamber for installing the liquid level switch 7;

[0027] The tank body 1 is provided with a seventh connection seat 18 below the static chamber for connecting the discharge pipe 6;

[0028] The tank body 1 is provided with a fourth socket 15 above the storage bin for connecting the monitoring tube 4;

[0029] The tank body 1 is provided with a sixth socket 16 above the storage bin for mounting the pressure sensor 8;

[0030] The tank body 1 is provided with a sixth connection seat 17 at 60% height (optional) on the side of the storage bin for connecting the discharge pipe 5, and the discharge pipe 5 is provided with a second electromagnetic switch valve 51, and the height of the sixth connection seat 17 is lower than the third connection seat 14;

[0031] The tank body 1 is provided with an eighth socket 19 below the storage bin for connecting the discharge pipe 6 , and the discharge pipe 6 is installed with a third electromagnetic switch valve 61 .

[0032] Among them, Figure 4 As shown, a cover 41 is installed on the monitoring tube 4, and an ammonia monitor 46 is installed in the cover 41; the cover 41 and the flange 42 are fastened and assembled by bolts 43 and nuts 44, and sealed by an O-ring 45.

[0033] The working process of this application is as follows:

[0034] During operation, the first electromagnetic switch valve 51 and the third electromagnetic switch valve 61 are in a closed state, and the second electromagnetic switch valve 31 is in an open state. The used lubricating oil enters the static bin from the oil inlet pipe 2. According to the principle of communicating vessels, the lubricating oil in the static bin will enter the storage bin through the gap under the partition and keep the liquid levels on both sides the same. In addition, after the lubricating oil enters the static bin, it needs to be left to stand for a certain period of time before the ammonia that may be mixed can be precipitated. The design purpose of the two chambers is to prevent the mixed ammonia from being undetected and then mixed with the lubricating oil and eliminated. The volume design of the tank body 1 should be sufficient to store the discharge volume of lubricating oil for fifty minutes (optional).

[0035] When the lubricating oil in the tank body 1 reaches the height of the sixth seat 17 , it will be discharged from the discharge pipe 5 to the recovery tank.

[0036] During the above operation, when the ammonia monitor 46 detects that the gas contains ammonia, the second electromagnetic switch valve 51 will be immediately closed, the first electromagnetic switch valve 31 will be opened, and 12 bar nitrogen will be continuously purged, and the purging gas will be discharged from the monitoring tube 4. When the ammonia monitor 46 detects that the gas does not contain ammonia, the second electromagnetic switch valve 51 will be opened. If the liquid level is higher than the liquid level switch 7, the third electromagnetic switch valve 61 will be opened. If the liquid level is lower than the liquid level switch 7, the third electromagnetic switch valve 61 will be closed.

[0037] During the above operation, when the pressure sensor detects that the pressure in the tank body 1 is higher than 1.5 bar, the electromagnetic switch valve 31 is closed and the third electromagnetic switch valve 61 is opened.

[0038] In summary, the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
