Abstract
The utility model discloses an air compensation and exhausting device of a ventilation cabinet. The air compensation and exhausting device of the ventilation cabinet is composed of an air exhausting fan, an air exhausting filter, an air compensation fan, an air exhausting frequency changer, an air compensation frequency changer, a control system, a control switch, the ventilation cabinet, an air exhausting volume damper, an air compensation volume damper, an air exhausting pipeline and an air compensation pipeline. The air compensation and exhausting device of the ventilation cabinet is characterized in that the air exhausting volume damper is connected with the air exhausting fan through the air exhausting pipeline, the air compensation volume damper is connected with the air compensation fan through the air compensation pipeline, the control switch is installed on the ventilation cabinet, the air exhausting filter is installed at the position of an outlet of the air exhausting pipeline, the control system is connected with the air exhausting frequency changer, the air compensation frequency changer, the control switch, the air exhausting volume damper and the air compensation volume damper, the air exhausting fan is connected with the exhausting frequency changer, and the air compensation fan is connected with the air compensation frequency changer. The air compensation and exhausting device of the ventilation cabinet has the advantages that noxious gas produced in a test and inside the ventilation cabinet can be exhausted, the environment temperature, the humidity and the air inside a laboratory will not be changed, and consumption of energy is greatly reduced.
Description
Technical field
The utility model relates to a kind of benefit wind air exhausting device of vent cabinet, uses a kind of benefit wind, air exhausting device that blower fan, pipeline, volume damper etc. are formed specifically.
Background technology
In order to guarantee good working environment, present laboratory all has been equipped with the open air exhaust device, because most laboratory indoor temperature, humidity and air-flow need steadily, the ability guarantee test carries out smoothly like this, for this reason, a large amount of energy have to be expended in present most of laboratory, heating or refrigeration indoor gas, the pernicious gas discharge that test produces by the exhaust equipment band again, only there is air exhausting device in present most vent cabinet, in winter or summer, when indoor/outdoor temperature-difference was bigger, indoor air was taken away in vent cabinet air draft meeting like this, cause the variation of indoor temperature easily, room air is taken away when avoiding air draft, so design a kind of benefit wind, air exhausting device, however such device do not had on the market.
Summary of the invention
At above-mentioned deficiency, the utility model provides a kind of benefit wind air exhausting device of vent cabinet.
The utility model is achieved through the following technical solutions: a kind of benefit wind air exhausting device of vent cabinet, be by the air draft blower fan, exhaust-air filter, mend the wind blower fan, the air draft frequency converter, mend the wind frequency converter, control system, gauge tap, vent cabinet, the air draft volume damper, mend the wind volume damper, exhaust duct, the secondary air channel road is formed, it is characterized in that: the air draft volume damper is connected with the air draft blower fan by exhaust duct, mending the wind volume damper is connected with benefit wind blower fan by the secondary air channel road, gauge tap is installed on the vent cabinet, exhaust-air filter is installed in the exhaust duct exit, control system and air draft frequency converter, mend the wind frequency converter, gauge tap, the air draft volume damper, mending the wind volume damper connects, the air draft blower fan is connected with the air draft frequency converter, mends the wind blower fan and is connected with benefit wind frequency converter.
The usefulness of this utility model is: when this device moves at vent cabinet, the wind that vent cabinet is discharged is directly mended by outdoor wind, the pernicious gas that test in the vent cabinet produces is discharged, do not cause the conversion of experiment indoor environment temperature, humidity and air-flow, the consumption of saving the energy greatly.
Description of drawings
Fig. 1 is a kind of structural representation of testing stand open air exhaust device.
Among the figure, 1 is that air draft blower fan, 2 is that exhaust-air filter, 3 is that benefit wind blower fan, 4 is that air draft frequency converter, 5 is that benefit wind frequency converter, 6 is that control system, 7 is that gauge tap, 8 is that vent cabinet, 9 is that air draft volume damper, 10 is that benefit wind volume damper, 11 is that exhaust duct, 12 is the secondary air channel road.
The specific embodiment
A kind of benefit wind air exhausting device of vent cabinet, be by air draft blower fan 1, exhaust-air filter 2, mend wind blower fan 3, air draft frequency converter 4, mend wind frequency converter 5, control system 6, gauge tap 7, vent cabinet 8, air draft volume damper 9, mend wind volume damper 10, exhaust duct 11, secondary air channel road 12 is formed, it is characterized in that: air draft volume damper 9 is connected with air draft blower fan 1 by exhaust duct 11, mending wind volume damper 10 is connected with benefit wind blower fan 3 by secondary air channel road 12, gauge tap 7 is installed on the vent cabinet 8, exhaust-air filter 2 is installed in exhaust duct 11 exits, control system 6 and air draft frequency converter 4, mend wind frequency converter 5, gauge tap 7, air draft volume damper 9, mending wind volume damper 10 connects, air draft blower fan 1 is connected with air draft frequency converter 4, mends wind blower fan 3 and is connected with benefit wind frequency converter 5.
During this device work, air draft blower fan 1, benefit wind blower fan 3 are opened simultaneously, during number change that vent cabinet 8 is opened, control system 6 control air draft frequency converters 4, benefit wind frequency converter 5 change of frequency, thereby control air draft blower fan 1, the variation of mending wind blower fan 3 air quantity, guarantee that by system's control back benefit wind blower fan 3 benefit air quantity and air draft blower fan 1 exhaust air rate the room air exhaust air rate minimizes, exhaust-air filter 2 is installed in air draft blower fan 1 exit, enters atmosphere after the pernicious gas of laboratory discharging can being handled.
Claims (2)
1. the benefit wind air exhausting device of a vent cabinet, be by the air draft blower fan, exhaust-air filter, mend the wind blower fan, the air draft frequency converter, mend the wind frequency converter, control system, gauge tap, vent cabinet, the air draft volume damper, mend the wind volume damper, exhaust duct, the secondary air channel road is formed, it is characterized in that: the air draft volume damper is connected with the air draft blower fan by exhaust duct, mending the wind volume damper is connected with benefit wind blower fan by the secondary air channel road, gauge tap is installed on the vent cabinet, exhaust-air filter is installed in the exhaust duct exit, control system and air draft frequency converter, mend the wind frequency converter, gauge tap, the air draft volume damper, mending the wind volume damper connects, the air draft frequency converter is connected with the air draft blower fan, mends the wind frequency converter and is connected with benefit wind blower fan.
