Examples
Referring to fig. 1, the present embodiment provides an exhaust emission device capable of controlling air pressure, including:
an exhaust gas source 1, i.e. the location where exhaust gas is generated;
the drainage pipeline 2 is vertically arranged, and the upper end of the drainage pipeline is communicated with the waste gas source 1;
the exhaust pipeline 3 is horizontally arranged, and one end of the exhaust pipeline is communicated with the lower end of the drainage pipeline 2;
the nozzle 4 is arranged at the upper end of the drainage pipeline 2 and the spraying direction is downward; the nozzle 4 is of a structure mature in the field, and is generally communicated with a liquid source when in use, and the liquid is pumped to the nozzle 4 from the liquid source by a pump and then sprayed out; in practical application, the nozzle 4 is communicated with a high-pressure water source, and the high-pressure water column is sprayed through the nozzle 4, so that the air flow velocity can be improved to a greater extent, and the air pressure in the pipeline can be reduced to a greater extent;
a liquid storage tank 5 located below the drainage pipe 2 and communicating with the interior of the drainage pipe 2, the liquid storage tank 5 being adapted to collect the liquid sprayed by the nozzle 4; the liquid storage tank 5 can be an independent structure, and can also be a structure formed by integrally extending the drainage pipeline 2 or the exhaust pipeline 3; the specific shape of the liquid storage tank 5 is not limited, and the liquid storage tank can mainly store liquid, and can be specifically spherical or box-shaped or other common shapes;
the electromagnetic valve is suitable for controlling the opening and closing of the nozzle 4; the electromagnetic valve is a mature structure in the field and is installed at the nozzle 4 when in specific use;
a pressure sensor 6 adapted to detect the pressure of the transport gas; the installation position of the pressure sensor 6 is not limited, and the pressure sensor can be arranged in the drainage pipeline 2, the exhaust pipeline 3 or the air outlet of the waste gas source 1;
and the controller is connected with the pressure sensor 6 and the electromagnetic valve and is suitable for controlling the electromagnetic valve to be opened when the detection value of the pressure sensor 6 is greater than a preset value and controlling the electromagnetic valve to be closed when the detection value of the pressure sensor 6 is less than the preset value.
In the exhaust gas discharge device of the present embodiment, the injection direction of the nozzle 4 is the same as the gas flow direction, and the flow velocity of the gas in the pipe can be increased by injecting the high-pressure liquid column, so that the gas pressure in the pipe is reduced. Moreover, the device is provided with the pressure sensor 6, the electromagnetic valve and the controller, so that the automatic control of the air pressure in the pipeline can be realized, and the gas leakage caused by overhigh air pressure in the pipeline is avoided.
As a preferable structure of the liquid storage tank 5, the liquid storage tank 5 is formed by extending a lower side pipe wall of the exhaust pipe 3 downward. During manufacturing, the liquid storage tank 5 and the exhaust pipeline 3 are integrally formed, processing is more convenient, and the problem of tightness of connection of the two parts does not need to be considered. Of course, in other embodiments, the liquid storage tank 5 may be a separate structure, and is fixed on the lower side of the exhaust duct 3, so long as it is communicated with the inside of the exhaust duct 3.
As a preferred shape of the reservoir 5, the reservoir 5 is hemispherical, which facilitates the entry of the liquid sprayed by the nozzle 4. Of course, in other embodiments, the reservoir 5 may be a square box or a rectangular box.
As a further improvement of the above technical solution, the method further comprises:

and the connecting pipeline 8 is obliquely arranged, the upper end of the connecting pipeline is communicated with the upper end of the air inlet pipeline 7, and the lower end of the connecting pipeline is communicated with the upper end of the drainage pipeline 2.
When the waste gas treatment device is used, waste gas generated by the waste gas source 1 sequentially passes through the air inlet pipeline 7, the connecting pipeline 8, the drainage pipeline 2 and the exhaust pipeline 3 and then is discharged. The air inlet pipeline 7 and the connecting pipeline 8 are additionally arranged, so that the subsequent drainage pipeline 2 and the exhaust pipeline 3 can be arranged higher, and the spatial arrangement is more convenient and reasonable.
As a preferred mounting position of the pressure sensor 6, the pressure sensor 6 is mounted at a lower portion of the intake duct 7. Because the waste gas is conveyed outwards from the waste gas source 1, the position closer to the waste gas source 1 is more prone to generate an overlarge phenomenon when the air pressure does not reach the balance, the pressure sensor 6 is arranged at the lower part of the air inlet pipeline 7 and is close to the outlet of the waste gas source 1, so that as long as the detected air pressure does not exceed a set value, the air pressure in the whole pipeline can be guaranteed not to exceed a preset value, and the performance is more reliable.

When the water amount in the liquid storage tank 5 is excessive, the controller controls the liquid discharge valve 9 to open for liquid discharge; when the water amount in the liquid storage tank 5 does not reach the preset value, the controller controls the liquid discharge valve 9 to be closed, so that the automatic treatment of the liquid in the liquid storage tank 5 can be realized.
