In order to reduce the influence of corrosive gas on the corrosion of the vacuum pump and the production process, a gas absorption device is arranged in the production process. The gas generated by the common production device enters the gas absorption device through the vacuum buffer tank and is connected with the vacuum pump through the buffer tank. Therefore, the damage of corrosive gas to the vacuum pump can be effectively reduced, and the phenomenon of suck-back caused under the condition of vacuum pump failure or sudden power failure can be effectively avoided.
The utility model has the following contents:
to the above problem, the to-be-solved technical problem of the utility model is to provide a vacuum buffer absorption device, including vacuum buffer tank, corrugated metal pipe, gaseous absorption tank and vacuum pump, gaseous absorption tank is including the gaseous absorption tank jar body, level gauge, linker, baffle and second manometer, the internal portion of gaseous absorption tank divide into cavity and cavity down through the baffle, vacuum buffer tank communicates to the cavity down of the gaseous absorption tank jar body through corrugated metal pipe, the cavity passes through linker and last cavity intercommunication down, be equipped with the level gauge on the cavity down, be equipped with first manometer on the vacuum buffer tank, be equipped with the second manometer on the gaseous absorption tank, the vacuum pump is connected to the gaseous absorption tank.
Preferably, a valve is arranged between the gas absorption tank and the vacuum pump.
Preferably, a flange is arranged on the metal corrugated pipe.
The utility model discloses beneficial effect: the utility model discloses can avoid the corrosive waste gas to get into the vacuum pump among the chemical production vacuum distillation process, guarantee that the process normally goes on, if under vacuum pump stop work or the power failure suddenly under emergency, also can guarantee that the absorption liquid can not suck backward to the process equipment in, for traditional equipment, this equipment is simple economy more.
Description of the drawings:
for ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of a gas absorption canister during normal operation.
In the figure: 1-vacuum buffer tank; 2-a metal bellows; 3-a liquid level meter; 4-absorption liquid level identification; 5-a communicating vessel; 6-a separator; 7-a first pressure gauge; 8-a second pressure gauge; 9-gas absorption tank body; 10-a vacuum pump; 11-the upper layer of the clapboard is used for identifying the liquid level of the absorption liquid.
The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1-2, the utility model discloses a vacuum buffer absorption device, including vacuum buffer tank 1, corrugated metal pipe 2, gaseous absorption tank and vacuum pump 10, gaseous absorption tank is including the gaseous absorption tank jar body 9, level gauge 3, linker 5, baffle 6 and second manometer 8, the internal portion of gaseous absorption tank jar is divided into cavity and lower cavity through baffle 6, vacuum buffer tank 1 communicates to the lower cavity of the gaseous absorption tank jar body 9 through corrugated metal pipe 2, the cavity passes through linker 5 and last cavity intercommunication down, be equipped with level gauge 3 on the lower cavity, be equipped with first manometer 7 on vacuum buffer tank 1, be equipped with second manometer 8 on the gaseous absorption tank, vacuum pump 10 is connected to the gaseous absorption tank.
Specifically, a valve is arranged between the gas absorption tank and the vacuum pump 10, and a flange is arranged on the metal corrugated pipe 2.
Specifically, the liquid level mark 4 in the figure is used for indicating the position of the liquid level section of the absorption liquid, and the liquid level mark 11 on the upper layer of the clapboard in the figure is used for indicating the position of the liquid level section of the absorption liquid on the upper layer of the clapboard.
The working principle is as follows: before the beginning of the chemical process such as the reduced pressure distillation process, the vacuum pump 10 is started, the normal operation is confirmed, after the production condition is met, the valve between the gas absorption tank and the vacuum pump 10 is started, after the pressure of the second pressure gauge 8 is confirmed to meet the production requirement, the valve between the vacuum buffer tank 1 and the process device is started, and the process is normally carried out. Corrosive gas generated in the technical process enters a vacuum buffer tank 1, passes through a metal corrugated pipe 2 (the influence of equipment vibration on a pipeline is effectively reduced), enters a gas absorption tank after entering the gas absorption tank, enters a liquid level mark 4 of absorption liquid of the gas absorption tank above the liquid level of the absorption liquid, the absorption liquid enters a communicating vessel 5 above a partition plate 6 from a communicating vessel 5 opening below the liquid level mark 4 of the absorption liquid, the communicating vessel 5 is filled with the absorption liquid at the moment, and a small amount of absorption liquid also exists on the upper layer of the partition plate 6. When the position of the absorption liquid level mark 4 is lowered and is parallel to the position of the opening of the communicating vessel 5 below the partition plate 6 (as shown in fig. 2), the corrosive gas enters the upper layer of the partition plate 6 from bottom to top through the communicating vessel 5 and finally enters the vacuum pump 10. In this process, the communicating vessel 5 is filled with the absorbing liquid, and the corrosive gas is absorbed by the absorbing liquid in the communicating vessel 5 and the absorbing liquid in the upper partition plate 6 during the flowing process. When the technological process is stopped and the vacuum pump 10 stops working, a small amount of absorption liquid on the upper layer of the partition plate automatically flows into the absorption liquid on the lower layer.
Under an abrupt condition (such as a vacuum pump failure or an abrupt power failure condition), the absorption liquid on the upper layer of the partition plate 6 shown in fig. 2 automatically enters the lower layer, only a small amount of absorption liquid splashes into the pipeline of the metal corrugated pipe 2, and a large amount of absorption liquid cannot enter the vacuum buffer tank 1, so that the absorption liquid cannot enter a process production device.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
