Definitions
- the invention relates to an automatic exhaust device and method, in particular to a vacuumless pump automatic exhaust device and method for a lithium bromide unit.
- the lithium bromide unit can have an automatic air pumping device, when the internal gas is discharged to the atmosphere, the palladium tube or the mechanical vacuum pump is often used, and the palladium tube is a precious metal, which is expensive, and can only pump hydrogen gas, and cannot pump other gases. Failure to avoid cooling capacity and corrosion during leakage.
- the vacuum pump will extract the moisture of the solution in the unit as steam. The water vapor is liquefied in the vacuum pump to emulsify the vacuum pump oil. If there is no oil vacuum pump, the liquid hammer will cause the pumping speed to drop, the ultimate pressure rises, and even the vacuum pump will rust and card. Dead and the motor burned.
- the technical problem to be solved by the present invention is: to provide a lithium bromide unit that does not require a palladium tube or a vacuum pump, can also automatically discharge internal gas to the atmosphere, effectively compresses the unit structure, and increases operational reliability, in view of the above-mentioned deficiencies of the prior art. Vacuumless pump automatic exhaust device and method.
- the vacuumless pump automatic exhausting device of the lithium bromide unit comprises an automatic air extracting device, a pumping chamber, a gas-liquid separation chamber and a gas storage chamber, and the automatic air pumping device does not pass through the air intake tube.
- the condensed gas is introduced into the pumping chamber, and the pumping chamber is then injected into the gas-liquid separation chamber through the exhaust pipe.
- the gas in the gas-liquid separation chamber is connected to the gas storage chamber by the gas-conducting and liquid-returning tubes, and the gas-liquid separation chamber solution is separated. Then returning to the inside of the unit through the pipeline, the invention provides a valve in the solution pump outlet pipe of the lithium bromide unit
- the valve group disposed at the top of the air storage chamber includes a rubber ball liquid-repellent exhaust self-sealing valve and a spring one-way exhaust valve, and a solenoid valve or an electric valve can also be added, and the rubber ball is blocked from the valve body of the closed valve.
- the cone surface and the lower cone surface have free suspension rubber balls in the middle, and the density of the rubber balls is less than the solution.
- the invention utilizes the existing solution and solution pump in the unit, and changes the flow direction of the solution through the action of the valve, so that the lithium bromide unit is automatically exhausted, no vacuum pump or palladium tube is needed, the unit structure is enlarged and the operation reliability is increased. It avoids the defects that the palladium tube is expensive, can only pump hydrogen, can not pump other gases, the leakage capacity of the unit leaks and corrosion, and avoids the use of vacuum pump oil emulsification or liquid hammer, pumping speed drop, ultimate pressure rise, pump corrosion, The invention effectively simplifies the structure of the unit, increases the operational reliability of the unit, and improves the technical performance of the unit.
- FIG. 2 is a schematic view showing the structure of a rubber ball liquid-repellent exhaust self-sealing valve according to the present invention
- the vacuumless pump automatic exhaust device of the lithium bromide unit includes an automatic pumping device.
- the air pumping chamber, the gas-liquid separation chamber, the air storage chamber, the automatic air suction device introduces the non-condensable gas in the unit into the pumping chamber through the air inlet pipe 1, and the pumping chamber is ejector through the air pumping tube 2 to the gas and liquid through the air pumping tube
- the gas in the gas-liquid separation chamber is connected to the gas storage chamber by the gas-conducting and liquid-returning tubes 3, and the gas-liquid separation chamber solution is returned to the inside of the unit through the pipeline 4, and the gas is required to be discharged into the atmosphere when the gas is accumulated in the gas storage chamber.
- the invention provides a valve F1 in the outlet pipe of the solution pump 5 of the lithium bromide unit, and an exhaust liquid inlet pipe 6 is taken between the solution pump 5 and the valve F1 to the air storage chamber, and a valve is arranged between the exhaust liquid inlet pipe 6.
- F2 a gas guiding and returning liquid pipe 3 between the gas storage chamber and the gas-liquid separation chamber is provided with a valve F3, and a valve group is arranged at the top of the gas storage chamber.
- the valve group includes a rubber ball liquid venting self-sealing valve 7 and a spring one-way venting valve 8, and can also increase the force ⁇ solenoid valve or electric valve.
- the rubber ball is vented from the closed valve.
- the valve body 12 has an upper tapered surface 9 and a lower tapered surface 10, and a free suspension rubber ball 11 in the middle, and the density of the rubber ball 11 is smaller than the solution.
- the spring one-way exhaust valve 8 closes the valve by the spring pressure. When the pressure inside the valve exceeds the spring pressure, the valve automatically opens, otherwise it closes.
- No vacuum pump automatic exhaust method When there is more gas in the air storage chamber, close the valves Fl, F3, open the valve F2 and the solution pump 5, press the solution into the air storage chamber, the gas in the storage chamber is compressed, and the compressed gas pressure When a certain amount of atmospheric pressure is exceeded, the spring one-way exhaust valve 8 is opened, and the gas is automatically discharged. When the gas is exhausted, the solution vents the rubber ball from the rubber ball of the closed valve to form a seal with the upper tapered surface 9. , to prevent the solution from squirting.
