A kind of machine room supply air systemTechnical field
The utility model relates to a kind of supply air system, relates in particular to a kind of machine room supply air system.
Background technology
Machine room is owing to there are a large amount of chemical materials, easily produce a large amount of harmful waste gas, in order to reduce Health cost to the staff, just need in time these waste gas to be discharged, at present, machine room generally adopts air draft unit and air-supply unit to take a breath simultaneously: adopt on one side and with exhaust system waste gas is discharged, air interior between renovated bus is come with the way that supply air system compensates new wind in one side, wherein the air draft blower fan is in conjunction with exhaust duct and press oven, form the cabinet type hood of many groups, wherein pressure of inspiration(Pi) is pressed greater than air-supply, thus the harmful steam control and the discharge that produce will dry the time.Blower-use is carried out the workshop by air outlet and is blown comprehensively in remedying the indoor negative pressure that local exhaust causes in addition.But this method needs pressure fan uninterruptedly to suck air from the external world, and the general power of pressure fan is bigger, and this just makes machine room's supply air system energy consumption big, increases production cost, and unfavorable environmental protection.
Summary of the invention
The purpose of this utility model is exactly machine room's supply air system that a kind of energy-conserving and environment-protective are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of machine room supply air system, it is characterized in that: this system comprises: exhaust blower, exhaust outlet, exhaust duct, air outlet, air supply duct, described exhaust blower one end connects exhaust outlet, the other end connects press oven by exhaust duct, described air outlet is arranged on directly over the personnel channel of machine room, described air supply duct one end connects air outlet, and the other end is connected to outside the machine room.
In the described air outlet filter is set.
Described air outlet is provided with 4-10.
The utility model pressure fan of stopping using, change that initiatively to mend wind be passive benefit wind, open the passive wind-supplying mouth of many groups, and in conjunction with transforming air supply duct, air outlet is moved to directly over the personnel channel, make clean air along personnel channel, work contaminated area, outdoor direction circulation, a plurality of air outlets are set evenly distributes whole workshop air-supply air-flow, reduce the eddy current dead angle, avoid the local deposits of nuisance, establish filter in the passive air outlet and prevent that dust from going into the workshop with the direct perfusion of outdoor air and causing pollution.Utilize the draught head of indoor and outdoor, fresh air is sent into the workshop, finish, significantly reduced the electricity consumption of using the pressure fan air-supply, saved the energy, help environmental protection the workshop air-supply by the air outlet of setting up.
Description of drawings:
Fig. 1 is that a kind of machine room of the utility model supply air system is formed schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Embodiment 1
As shown in Figure 1, a kind of machine room supply air system, this system comprises: exhaust blower 1, exhaust outlet, exhaust duct 2, air outlet 3, air supply duct, described exhaust blower 1 one ends connect exhaust outlet, the other end connects press oven 4 by exhaust duct 2, and described air outlet 3 is provided with 6, disperses to be arranged on directly over the personnel channel of machine room, described air supply duct one end connects air outlet 3, and the other end is connected to outside the machine room.In the described air outlet 3 filter is set.
When exhaust blower 1 was discharged machine room's waste gas, the workshop internal gas pressure reduced, the inside and outside draught head that forms in workshop, and the workshop extraneous air just enters the workshop by air supply duct, air outlet 3, finishes benefit wind.In the described air outlet 3 filter is set, can be with waste gas, contaminant filter in the extraneous air, guaranteed that IAQ is good, for the staff is worked in good air ambient, described air outlet 3 is arranged on the personnel channel top, makes clean air along personnel channel, work contaminated area, outdoor direction circulation, and whole workshop air-supply air-flow is evenly distributed, reduce the eddy current dead angle, avoid the local deposits of nuisance.When the IAQ difference, machine room's supply air system can be according to the air quantity of exhaust blower air draft, open right quantity exhaust blower 1, set up air outlet 3, thereby strengthen air output, guarantee that the air pressure and the air quality in workshop is normal.
Embodiment 2
Described air outlet is provided with 4, disperses to be arranged on directly over the personnel channel of machine room.All the other are with embodiment 1.
Embodiment 3
Described air outlet is provided with 10, disperses to be arranged on directly over the personnel channel of machine room.All the other are with embodiment 1.
