Abstract
The utility model discloses an efficient fume extractor. The efficient fume extractor comprises two fume extraction systems. Each fume extraction system starts from an air suction port, then is connected with a primary filter, a fume exhaust fan, a secondary filter and a tertiary filter in sequence and is finally connected with an exhaust port. Each fume extraction system is provided with a pressure transmitter, negative pressure of an inlet can be observed on site, pressure signals can be transmitted to a master control room for online monitoring, and continuous and reliable operation of a unit system is guaranteed accordingly. A sewage draining exit is formed in the bottom of the efficient fume extractor. Each efficient fume extractor is provided with the two fume extraction systems, one operates, the other is standby, and the two fume extraction systems can be switched over. Each fume extraction system is provided with the pressure transmitter, the negative pressure of the inlet can be observed on site, the pressure signals can be transmitted to the master control room for online monitoring, and continuous and reliable operation of the unit system is guaranteed accordingly. The inlet of the fume extractor is provided with an adjustable positioning butterfly valve so that the negative pressure of the inlet of the fume extractor can be adjusted and fixed. The fans of the fume extractor are small in size, and the fume extractor is high in efficiency, stable in operation and free of noise.
Description
Technical field
The utility model relates to a kind of efficient fume extractor, is mainly used in the harmful substances such as oil smoke in Turbo-generator Set discharge turbine oil system, generator sealing oil system, hydrogen, moisture, to ensure lubricated and the pure and safe operation of sealing oil.
Background technology
The a lot of skyscrapers of fume extractor, underground engineering, traffic tunnel, place of public amusement fire incident cause the heaviness lesson of personnel's heavy casualties, make people clearly realize that the good smoke control system of design and installation and long-term good importance and the necessity of the performance of guaranteeing system.The fire fact is told us smoke control system can effectively be controlled spreading of flue gas in the time that fire occurs; And smoke evacuation rapidly in time, to rescuing people, disaster relief work plays a part crucial.
Utility model content
Object of the present invention provides a kind of efficient fume extractor, and this device has two cover smoke evacuation systems, and a set of operation is a set of for subsequent use, and can switch mutually.
The technical solution of the utility model is achieved in that efficient fume extractor; this device has two cover smoke evacuation systems; each smoke evacuation system starts from an air entry; then connect successively grade one filter, smoke exhaust fan, secondary filter, tertiary filter and finally connect exhaust outlet; every cover smoke evacuation system is furnished with pressure transmitter; both can field observation import negative pressure, pressure signal can be transported to again to master-control room in-service monitoring, to guarantee machine set system operation reliably continuously.Sewage draining exit is established in the bottom of described device.
One of them embodiment is: grade one filter is connected settling chamber with secondary filter.Every cover smoke evacuation system is provided with grade one filter and secondary filter, is discharged from air-flow after this two-stage filter, and profit is tentatively separated, is then discharged to tertiary filter, and the gas that dispatch goes out is purified outside discharge factory again.The various liquid dirts of separating, can remove together by being discharged to depositor under drainage.
One of them embodiment is: between secondary filter and tertiary filter, be provided with check-valves.
One of them embodiment is: this device air entry place is furnished with adjustable butterfly valve, to regulate and fixing induced-draft fan import negative pressure (suction), when the firsts and seconds of maintenance or cleaning one side filters from device, the adjustable butterfly valve of this side can cut out, can not affect the normal work of opposite side smoke evacuation system.
One of them embodiment is: the blade of smoke exhaust fan is made up of aluminium, and volume is little, and efficiency is high, operate steadily, and noiselessness.
The beneficial effects of the utility model are: every suit is equipped with two cover smoke evacuation systems, and a set of operation is a set of for subsequent use, and can switch mutually.Every cover smoke evacuation system is furnished with respectively pressure transmitter, both can field observation import negative pressure, pressure signal can be transported to again to master-control room in-service monitoring, to guarantee machine set system operation reliably continuously.Induced-draft fan import department is furnished with adjustable location butterfly valve, to regulate and fixing induced-draft fan import negative pressure (suction).Fume extractor blower fan volume is little, and efficiency is high, operate steadily, and noiselessness.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further explained to explanation.
As Figure 1-3; efficient fume extractor; this device has two cover smoke evacuation systems; each smoke evacuation system starts from an air entry 7; then connect successively the last exhaust outlet 1 that connects of grade one filter 4, smoke exhaust fan, secondary filter 2, tertiary filter 10, every cover smoke evacuation system is furnished with pressure transmitter 6, both can field observation import negative pressure; pressure signal can be transported to again to master-control room in-service monitoring, to guarantee machine set system operation reliably continuously.Sewage draining exit 11 is established in the bottom of described device.
Grade one filter is connected settling chamber 8 with secondary filter.Every cover smoke evacuation system is provided with grade one filter and secondary filter, is discharged from air-flow after this two-stage filter, and profit is tentatively separated, is then discharged to tertiary filter, and the gas that dispatch goes out is purified outside discharge factory again.The various liquid dirts of separating, can remove together by being discharged to settling chamber 8 under drainage.
Between secondary filter and tertiary filter, be provided with check-valves 9.
This device air entry place is furnished with adjustable butterfly valve 5, to regulate and fixing induced-draft fan import negative pressure (suction), when the firsts and seconds of maintenance or cleaning one side filters from device, the adjustable butterfly valve 5 of this side can cut out, can not affect the normal work of opposite side smoke evacuation system.
The blade of smoke exhaust fan is made up of aluminium, and volume is little, and efficiency is high, operate steadily, and noiselessness.
Fig. 4 is the fundamental diagram of efficient fume extractor, air-flow enters from air entry 7, through the adjustable butterfly valve 5 of wafer type, then pass through grade one filter 4, the smoke exhaust fan 3 of flowing through, then pass through secondary filter 2 and check-valves 9, finally by tertiary filter 10, discharged by exhaust outlet 1, whole smoke evacuation process completes.Three impurity that filter enter settling chamber 8, discharge through sewage draining exit.Pressure transmitter both can field observation import negative pressure, pressure signal can be transported to again to master-control room in-service monitoring.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
