Description

Drainage device for lithium bromide refrigerator
Technical Field
The utility model relates to a refrigeration plant field, a lithium bromide refrigerator drainage device is said in detail.
Background
As is well known, in the refrigeration industry, a lithium bromide refrigerator (hereinafter referred to as a bromine refrigerator) is an energy-saving device and is widely applied. However, as the operating life of the bromine refrigerator increases, copper pipes inside the unit may leak, and water and air may enter the unit due to the leakage of the copper pipes, which may cause pollution of the absorbent (lithium bromide solution) and the refrigerant (water), and the polluted absorbent or refrigerant may cause efficiency decrease, steam consumption increase, cold water temperature increase, refrigerator life shortening, maintenance cost increase, etc. of the bromine refrigerator. And when the conditions are serious, all the lithium bromide solutions in the whole machine need to be replaced or the machine set needs to be scrapped, and when the conditions are serious, all the lithium bromide solutions in the whole machine need to be replaced or the machine set needs to be scrapped.
The lithium bromide refrigerator is a cold water generator using water as refrigerant and lithium bromide water solution as absorbent, when the bromine refrigerator normally operates, the inside of the refrigerator is in negative pressure state (pressure is about 6mmHg), the inside of the evaporator is refrigerant (water), the inside of the absorber is absorbent (lithium bromide), the evaporator and the absorber are communicated at the top, but the water of the evaporator cannot overflow to the absorber, and only can be absorbed into the absorber by the lithium bromide solution in a state of water vapor.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a lithium bromide refrigerator drainage device, which not only can save the maintenance cost, but also can improve the working efficiency of the refrigerator.
The utility model provides a technical scheme that its technical problem adopted is: a drainage device of a lithium bromide refrigerator is provided with an evaporator and is characterized in that a valve at the bottom of the evaporator is installed at the bottom of the evaporator and is connected with a water pumping valve through a water pumping pipe, the water pumping valve is installed at the top of a closed water tank, a drain valve is installed at the bottom of the closed water tank, an emptying valve and a vacuumizing valve are further installed at the top of the closed water tank, the vacuumizing valve is connected with a vacuum pump through an air pumping pipe, and a liquid level meter communicated with the inner cavity of the closed water tank is installed on the side wall of the closed water tank.
The beneficial effects of the utility model are that, simple structure, low in manufacturing cost can discharge the water in the lithium bromide refrigerator evaporimeter fast, and the original function of recovery equipment in time reduces cost of maintenance simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a vacuum pumping valve, 2, a vent valve, 3, a water pumping valve, 4, a closed water tank, 5, a blow-down valve, 6, a vacuum pump, 7, an evaporator bottom valve and 8, an evaporator are arranged.
Detailed Description
In the figure, the utility model discloses be equipped with evaporimeter 8, evaporimeter bottom valve 7 is installed to evaporimeter 8 bottom, evaporimeter bottom valve 7 is through the drinking-water union coupling valve 3 that draws water, the valve 3 that draws water is installed at airtight water tank 4's top, blowoff valve 5 is installed to airtight water tank 4 bottom, atmospheric valve 2 and evacuation valve 1 are still installed at airtight water tank 4's top, evacuation valve 1 is through the pipe connection vacuum pump 6, install the level gauge that is linked together with airtight water tank 4 inner chamber on airtight water tank 4's the lateral wall.
Before use, the emptying valve 2, the water pumping valve 3 and the sewage discharging valve 5 are all closed, the vacuumizing valve 1 and the evaporator bottom valve 7 are opened, the vacuum pump 6 is started, and air in the closed water tank 4 begins to be pumped. After 4 vacuum pressure of airtight water tank reached the requirement, closed evacuation valve 1, opened the valve 3 that draws water, begin to extract the inside water of lithium bromide refrigerator evaporimeter 8, observe the level gauge on 4 lateral walls of airtight water tank, reach the high limit after when the liquid level, close the valve 3 that draws water, open simultaneously blow-down valve 2 and blowoff valve 5, discharge the water in 4 airtight water tank this moment, repeat this flow, can realize 8 drainage mesh to the evaporimeter of lithium bromide refrigerator.
