The ventilating cabinet can ensure that air speed in the ventilating cabinet can achieve the international universal standard which is 0.3 meter per second to 0.8 meter per second, and can reduce 40 percent to 60 percent of energy loss. So energy is saved.
Description
Technical field
The utility model relates to the vent cabinet that a kind of laboratory is used, and particularly a kind ofly toxic and harmful in the experimentation can be discharged to outdoor vent cabinet.
Background technology
At present; known vent cabinet mainly is made up of ventilation cabinet and exhaust system two parts; poisonous and harmful and dangerous experiment are all carried out in vent cabinet, and the toxic and harmful that will produce in the time of will testing by exhaust system is forced to be discharged to outdoor, protects the healthy of experiment operator.But a large amount of air drafts directly replenishes from indoor, and the heating installation in winter and the cold air in summer also are discharged from outdoor in a large number, can cause great energy loss.
Summary of the invention
In order to solve the problem that prior art exists, the utility model provides a kind of compensating ventilation cabinet vent cabinet, and it can replenish a certain amount of new wind from outdoor in vent cabinet, so a large amount of heating installation or cold air that reduce in the laboratory run off.
Compensating ventilation cabinet vent cabinet of the present utility model, it include vent cabinet 3 and be arranged on outdoor exhaust blower 1 and be connected vent cabinet 3 and exhaust blower 1 between exhaust duct 2, it also includes secondary air channel road 4 and is arranged on outdoor benefit blower fan 5, and secondary air channel road 4 is connected to be mended between blower fan 5 and the vent cabinet 3.
Further, above-mentioned vent cabinet also can have following characteristics: the bellows of benefit 3-2 is arranged below the deck plate 3-4 in vent cabinet 3, and secondary air channel road 4 is connected with benefit bellows 3-2, has wind-supplying mouth 3-1 on deck plate 3-4.
Respectively there is a vertical deflector 3-10 who is provided with the both sides that are positioned at secondary air channel interface 3-9 in mending bellows 3-2, and described deflector 3-10 is the splayed of expansion gradually from back to front, and its rear and front end is connected with the sidewall of mending bellows 3-2 respectively.
Wind-supplying mouth 3-1 is the long narrow shape and the outside that is positioned at vent cabinet 3 front side actuating doors 3-5, and wind-supplying mouth 3-1 parallels with the front portion of deck plate 3-4.
On deck plate 3-4, be positioned at wind-supplying mouth 3-1 place and also be provided with benefit wind deflector 3-3.
Described benefit wind deflector 3-3 is positioned at the front side of wind-supplying mouth 3-1 and fixes with deck plate 34.
Described benefit wind deflector 3-3 is sweptback arc.
The utility model replenishes the outdoor new wind of the required airflow 40%-60% of vent cabinet institute owing to can and be arranged on outdoor benefit blower fan 5 by secondary air channel road 4 in vent cabinet, avoided the loss of indoor cold air and heating installation.This vent cabinet can guarantee that the face wind speed of vent cabinet reaches the current international practice standard of 0.3-0.8 meter per second, can reduce the energy loss of 40%-60% again, has saved the energy.
The utility model is also by the benefit bellows below the deck plate, and wind is guided to the front of vent cabinet, through the wind-supplying mouth in the vent cabinet actuating doors outside, with the fixing flow direction of wind of wind-supplying mouth deflector, mends wind from vent cabinet actuating doors section in cabinet, can prevent that poison gas from leaking.The utility model design is mended air quantity less than exhaust air rate, to guarantee experiment safety.
