Detailed Description
A discharge device for gases with different specific gravities in a production space comprises a gas collection cover 1, an exhaust pipeline network 3 and an exhaust fan 2, wherein the gas collection cover 1 is arranged above an exhaust port of a reaction kettle, the gas collection cover 1 is connected to the exhaust pipeline network 3, the exhaust fan 2 is arranged on a tail main pipe of the exhaust pipeline network 3, and the tail main pipe of the exhaust pipeline network 3 is connected with a tail gas treatment system; and aiming at a collecting and discharging structure of gas in the production space, a surrounding air inlet pipeline 5 is arranged at the upper part or the top part of the production space, the air inlet pipeline 5 is communicated with an exhaust pipeline network 3, an exhaust check valve 6 and an exhaust fan 2 are arranged on a branch pipeline of the exhaust pipeline network 3 connected with the air inlet pipeline 5, a pipeline behind the exhaust fan 2 is connected with a tail gas treatment system, the air inlet pipeline 5 is provided with an exhaust hole 7, an electromagnetic valve is arranged at the exhaust hole 7, the air inlet pipeline 5 is connected with 2-4 heavy component gas collecting pipelines 8, and the outlet of the heavy component gas collecting pipeline 8 is arranged at the lower part of the production space and is close to the ground. The bottom of the production space is provided with a blast air duct 9, and a pipeline where the blast air duct 9 is arranged is provided with an air inlet one-way valve 10 and an air blower 11.
The operation of the device is as follows: when the gas is collected by the gas collecting hood 1 during charging or other operations for diffusing the gas, the gas is discharged to a subsequent exhaust gas treatment device by the exhaust fan 2 through the exhaust pipe network 3.
When gas is present in the production chamber: if the indoor gas is lighter than the air component, the mouth of the heavy component gas collecting pipeline 8 is closed, an exhaust hole 7 needs to be formed in the air inlet pipeline 5, and the light component gas enters the air inlet pipeline 5 from the exhaust hole 7 under the action of the exhaust fan 2, passes through the exhaust pipeline network 3, the outward discharge one-way valve 6 and the exhaust fan 2 and then enters a subsequent tail gas treatment device; if the specific gravity of the indoor floating gas is greater than that of the air, heavy component gas collecting pipelines 8 are required to be distributed around the indoor space, and electromagnetic valves at exhaust holes 7 of the air inlet pipeline are closed. Heavy component gas enters an air inlet pipeline 5 from a heavy component gas collecting pipeline 8 under the action of an exhaust fan 2, passes through an exhaust pipeline network 3, an outward discharge one-way valve 6 and the exhaust fan 2, and then enters a subsequent tail gas treatment device; if the specific gravity of the indoor gas is larger than that of the air and smaller than that of the air, the heavy component gas collecting pipeline 8 is required to be distributed around the indoor space, electromagnetic valves at exhaust holes 7 of the air inlet pipeline are required to be opened, the light component gas enters the air inlet pipeline 5 from the exhaust holes 7 under the action of the exhaust fan 2, the heavy component gas enters the air inlet pipeline 5 from the heavy component gas collecting pipeline 8 under the action of the exhaust fan 2, and the collected gas enters a subsequent tail gas treatment device after passing through the exhaust pipeline network 3, the outer discharge one-way valve 6 and the exhaust fan 2; the blower 11 continuously sends fresh air into the room through the air inlet one-way valve 10 and the air blowing duct 9.
