Problems solved by technology

[0002] Although the lithium bromide unit can have an automatic pumping device, palladium tubes or mechanical vacuum pumps are often used to discharge the internal gas to the atmosphere, and the palladium tube is a precious metal, which is expensive and can only pump hydrogen, not other gases. In case of leakage, it cannot avoid the decline of refrigeration capacity and corrosion
The vacuum pump will extract the moisture of the solution in the unit in the form of steam. The water vapor will be liquefied in the vacuum pump and emulsify the vacuum pump oil. dead and motor burned

Embodiment Construction

[0010] 1. Referring to Fig. 1, the automatic exhaust device without a vacuum pump of this lithium bromide unit includes an automatic air extraction device, an air extraction chamber, a gas-liquid separation chamber, and an air storage chamber. The inert gas is introduced into the pumping chamber, and the pumping chamber is ejected to the gas-liquid separation chamber through the pumping pipe 2 with a liquid flow. The solution returns to the inside of the unit through the pipeline 4, and when there is a lot of accumulated gas in the gas storage chamber, it needs to be discharged into the atmosphere.

[0011] 2. Referring to Fig. 1, the present invention is provided with valve F1 at the solution pump 5 outlet pipelines of lithium bromide unit, draws the exhaust gas inlet pipe 6 to the air storage chamber between the solution pump 5 and the valve F1, and sets the valve between the exhaust gas inlet pipe 6 F2, a valve F3 is set in the gas guiding and liquid return dual-purpose pip...

Abstract

The invention comprises an automatic air extractor, an aspirating chamber, a gas-liquid separating chamber and a gas-storage chamber. A first valve is disposed on the solution pump outlet pipeline of the lithium bromide unit. Between the solution pump and the first valve are led a second valve and an exhaust liquid inlet to the gas-storage chamber and the gas-liquid separating chamber is disposed a third valve for the air guide and liquid return dual-purpose tube. On top of the gas-storage chamber are disposed a self-closing valve and a spring non-return exhaust valve or a magnetic valve, or an electrically-operated valve.

Description

Technical field: [0001] The invention relates to an automatic exhaust device and method, in particular to an automatic exhaust device and method for a lithium bromide unit without a vacuum pump. Background technique: [0002] Although the lithium bromide unit can have an automatic pumping device, palladium tubes or mechanical vacuum pumps are often used to discharge the internal gas to the atmosphere, and the palladium tube is a precious metal, which is expensive and can only pump hydrogen, not other gases. Leakage cannot avoid the decline in refrigeration capacity and corrosion. The vacuum pump will extract the moisture of the solution in the unit in the form of steam. The water vapor will be liquefied in the vacuum pump and emulsify the vacuum pump oil. dead and motor burned. Invention content: [0003] The technical problem to be solved by the present invention is to provide a lithium bromide unit that does not need a palladium tube or a vacuum pump, can also automati...
