Description
Technical Field
The utility model relates to a general exhaust emission system's of toilet flowing back device belongs to piping installation technical field.
Background
At present, a general waste gas discharge system of a clean room factory realizes the balance of gas inlet and outlet of the clean room factory by absorbing the exhaust pressure of the clean room and absorbing the atmospheric pressure, and ensures the cleanliness and the odorless production environment. When the device is used for producing the clean room factory building, the general waste gas generated by the device is exhausted through the exhaust fans of various exhaust systems outside the roof, and the frequency of the exhaust fans is adjusted through the pressure difference value of the air pipe pressure detection negative pressure transmitter (namely, the pressure difference is formed by detecting the exhaust pressure of the clean room one way and detecting the atmospheric pressure one way), so that the balance of air inlet and outlet, the cleanliness and the odorless production environment of the clean room factory building are ensured.
After the waste gas condensation waste liquid is amasss in the pipe, the waste liquid can flow to both sides negative pressure monitoring point, causes following consequence: 1) waste liquid enters the interior of the negative pressure transmitter, and needs to be maintained, so that the cost is increased; 2) the pressure alarm is caused, the exhaust frequency of various exhaust fans is influenced, the exhaust of a clean room is insufficient, the exhaust of the clean room is insufficient, and the production environment of a production line is influenced; 3) the general exhaust pressure is alarmed, so that the detection misjudgment of production line equipment is caused, the production line is shut down, and the production is influenced. In order to ensure the normal operation of a general waste gas discharge system, the absorption atmosphere pipe and the absorption exhaust pipe need to be frequently checked and maintained, and the negative pressure transmitter needs to be regularly checked or replaced, so that a large amount of manpower and material resources are wasted; or a filter is installed at a general exhaust gas suction port, but installation and maintenance costs are greatly increased.
Disclosure of Invention
The utility model aims to provide a general exhaust emission system's of toilet drain device is guaranteed negative pressure changer measured data's accuracy to the problem that the general exhaust emission system waste gas condensation waste liquid of current toilet factory building is difficult to discharge and leads to equipment trouble to guarantee the production environment of the business turn over of toilet factory building, give vent to anger balance, cleanliness factor and odorless.
The technical solution of the utility model is as follows: the liquid draining device for common waste gas exhausting system in clean room includes exhaust wind pipe, liquid draining valve and waste liquid collecting tank; one end of the liquid discharge pipe is connected with the middle part of the exhaust air pipe in the clean room, and the other end of the liquid discharge pipe is connected with the waste liquid collecting tank through a liquid discharge valve.
One end of the exhaust air pipe in the clean room is provided with an exhaust air pipe outside the clean room and an exhaust fan, the other end of the exhaust air pipe is provided with a negative pressure transmitter, and the bottom of the negative pressure transmitter is provided with an absorption atmosphere pipe and an absorption exhaust pipe which jointly form a general waste gas discharge system of the clean room; the liquid discharge valve is a one-way valve, and a spring is arranged in the liquid discharge valve.
The utility model has the advantages that:
1) the waste liquid accumulated in the pipe is effectively removed, and the influence of the backflow of the accumulated waste liquid on the production environment of the clean room is avoided;
2) the production environment of the clean room is ensured, so that the capacity and the yield of the clean room product are also ensured;
3) the pollution of the waste liquid to the monitoring pipeline equipment on two sides is reduced, and the equipment maintenance cost is reduced;
4) the accuracy of the monitoring data is ensured;
5) the transformation is easy, the cost is low, and the later maintenance is simple.
Drawings
FIG. 1 is a schematic structural view of a drain device of a general exhaust gas discharge system of a clean room.
In the figure, 1 is an absorption atmosphere pipe, 2 is an absorption exhaust pipe, 3 is a negative pressure transmitter, 4 is an exhaust air pipe in a clean room, 5 is an exhaust air pipe outside the clean room, 6 is an exhaust fan, 7 is a drain pipe, 8 is a drain valve, and 9 is a waste liquid collecting tank.
Detailed Description
As shown in fig. 1, a liquid discharge device of a general exhaust gas discharge system of a clean room structurally comprises an exhaust air duct 4, a liquid discharge duct 7, a liquid discharge valve 8 and a waste liquid collecting tank 9 in the clean room; wherein one end of the liquid discharge pipe 7 is connected with the middle part of the exhaust air pipe 4 in the clean room, and the other end is connected with a waste liquid collecting tank 9 through a liquid discharge valve 8.
One end of the exhaust air pipe 4 in the clean room is provided with an exhaust air pipe 5 and an exhaust fan 6 outside the clean room, the other end of the exhaust air pipe is provided with a negative pressure transmitter 3, the bottom of the negative pressure transmitter 3 is provided with an absorption atmosphere pipe 1 and an absorption exhaust pipe 2, and a general exhaust gas discharge system of the clean room is formed together.
The liquid discharge valve 8 is a one-way valve (SMC type AD 402-04), a spring is arranged in the liquid discharge valve, and the waste gas discharge system is in a closed state when working normally, so that the normal exhaust of the exhaust air pipe is not influenced.
When the automatic liquid discharge valve 8 is used, water or condensed waste liquid gathered in the exhaust air pipe 4 in the clean room falls into the liquid discharge pipe 7 through the through holes on the pipe wall, when the weight of the waste liquid on the upper part of the liquid discharge valve 8 is larger than the closing pressure of the spring of the automatic liquid discharge valve 8, the liquid discharge valve 8 is opened to discharge the waste liquid into the waste liquid collection tank 9, and after the waste liquid is discharged, the spring resets and closes the liquid discharge valve 8. The drain valve 8 is opened and closed repeatedly, so that the moisture or condensed waste liquid in the exhaust air pipe 4 in the clean room can be effectively removed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
