The utility model has the advantages of can store the waste gas of vacuum pump.
Description
Technical Field
The utility model belongs to the technical field of exhaust-gas treatment equipment, a vacuum pump waste gas storage tank is related to.
Background
The sewage treatment workshop of pharmaceutical factory adopts vertical vacuum pump to carry out the evacuation to sewage reation kettle, makes sewage react in the vacuum environment, however, also contains a certain amount of harmful gas in the gas that the vacuum pump was taken out from, and this part gas can not directly discharge, if give vent to anger at the vacuum pump and hold the processing apparatus who sets up harmful gas and do not have higher price/performance ratio, because waste gas volume output rate is little, set up exhaust-gas treatment equipment's with high costs alone.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a vacuum pump waste gas storage tank to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem how to make vacuum pump exhaust waste gas can be collected.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a vacuum pump waste gas storage tank, its characterized in that, includes jar body and the gasbag that is located jar internal, be provided with air inlet and gas outlet on the gasbag, the air inlet communicates with the end of giving vent to anger of vacuum pump, form a pressure chamber between gasbag and the internal wall of jar, be provided with the pressure release hole between intercommunication pressure chamber and the external world on the jar body, the downthehole pressure limiting valve that is provided with of pressure release.
Furthermore, a pressure sensor is arranged in the air bag.
The air inlet of gasbag is connected to the end of giving vent to anger of vacuum pump, the jar body is under the initial state, the air that the pressurize intracavity has certain pressure, the air of messenger's gasbag has certain pressure, setting through the pressure limiting valve, make the pressure in the gasbag maintain relatively stable, the gas of vacuum pump combustion gas gets into in the gasbag, waste gas stores in the gasbag, along with the increase of exhaust gas volume, the gasbag volume increases, and its pressure then can not take place great change, avoid its normal work that influences the vacuum pump, when gasbag and jar internal wall exist and paste and lean on, pressure sensor detects the great signal of gasbag internal pressure, it reaches the limit to show gasbag gas storage volume, at this moment need discharge waste gas to appointed treatment facility through the gas outlet, make the pressurize chamber resume the initial state, this waste gas storage tank is used for accepting the waste gas of vacuum pump again.

In the figure, 1, a tank body; 2. an air bag; 3. an air inlet; 4. a pressure maintaining cavity; 5. a pressure relief vent; 6. a pressure sensor.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the vacuum pump comprises a tank body 1 and an air bag 2 located in the tank body 1, wherein an air inlet 3 and an air outlet are arranged on the air bag 2, the air inlet 3 is communicated with an air outlet end of a vacuum pump, a pressure maintaining cavity 4 is formed between the air bag 2 and the inner wall of the tank body 1, a pressure relief hole 5 communicated between the pressure maintaining cavity 4 and the outside is arranged on the tank body 1, a pressure limiting valve is arranged in the pressure relief hole 5, and a pressure sensor 6 is arranged in the air bag 2.
The air inlet 3 of gasbag 2 is connected to the end of giving vent to anger of vacuum pump, jar body 1 is under the initial state, the air that has certain pressure in the pressurize chamber 4, make the admitting air of gasbag 2 have certain pressure, setting through the voltage limiting valve, make the pressure in the gasbag 2 maintain relatively stable, the gas of vacuum pump combustion gas gets into in the gasbag 2, waste gas is stored in gasbag 2, along with the increase of exhaust gas volume, 2 volume increases of gasbag, and great change then can not take place for its pressure, avoid its normal work that influences the vacuum pump, when gasbag 2 and jar body 1 inner wall exist and lean on, pressure sensor 6 detects the great signal of 2 internal pressure of gasbag, it reaches the limit to show 2 gas storage volumes of gasbag, at this moment need discharge waste gas to appointed treatment facility through the gas outlet, make pressurize chamber 4 resume the initial state, this waste gas storage tank is used for accepting the waste gas of vacuum pump again.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
