Abstract
The utility model provides a kind of dust proof workshop forced draft system, and this system includes new wind expansion chamber, frequency conversion Fresh air handling units, room pressure sensor.It is characterized in that it uses independently Fresh air handling units to carry new wind to maintain the malleation in workshop to workshop.And use the differential pressure pickup being arranged on workshop to sense workshop pressure and pressure signal be transferred to new wind fan frequency converter to reach control workshop resh air requirement, thus to make workshop malleation keep constant, the use of this forced draft system makes dust proof workshop over-pressure control obtain reliable guarantee, workshop antijamming capability is improved, and this system is adapted to the large dust proof workshop of air leak rate of air curtain especially.
Description
Technical field
The utility model relates to air-conditioning technical field, especially designs dust proof workshop supply air system.
Background technology
The constant control of dust proof workshop pressure difference is the problem of a more complicated, and it is a homeostasis process of workshop air output, inleakage, return air amount.The dust proof workshop that particularly inleakage is large relies on the negative pressure of air-conditioner set to suck the method for new wind, and the malleation being difficult to realize workshop is constant.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of dust proof workshop independently forced draft system.For achieving the above object, the technical scheme that the utility model provides is: use a kind of dust proof workshop independently forced draft system, and this cover system is only born workshop malleation and maintained task, and the adjustment of workshop epidemic disaster is born by air-conditioner set.Its novelty is that it separates from two functions of workshop clean air conditioner unit, becomes independently system.
This system includes new wind expansion chamber, frequency conversion Fresh air handling units, room pressure sensor:
Described new wind expansion chamber have by filter mechanism by the function of the dust filtering in air.It comprises new Windsock type roughing efficiency air filter, new Windsock type medium effeciency filter, negative-pressure type AD.
New Windsock type roughing efficiency air filter is for retaining the bulky grain in outside air, and mainly the suspension particulate of more than 5um and the particulate of more than 10um and various foreign matter, prevent it from entering.
New Windsock type medium effeciency filter is for retaining the suspension particulate of 1-5um, and namely its efficiency be as the criterion to filter 1um.
Negative-pressure type AD to have under negative pressure condition the trend of automatically closing, and has under negative pressure state and make aeroseal performance reliably.
The function of frequency conversion fan is the appropriate air quantity carried to workshop by changing motor speed.
Pressure sensor, also claims differential pressure pickup can sense the difference of workshop pressure and ambient pressure, and exports after changing this difference into the signal of telecommunication, by Frequency Converter Control rotation speed of fan.
Accompanying drawing explanation
Fig. 1 is the utility model system schematic
Wherein: the new Windsock type roughing efficiency air filter of 1-, 2-negative-pressure type AD, the new Windsock type medium effeciency filter of 3-, 4-frequency conversion fan, 5-frequency converter, 6-differential pressure pickup
Fig. 2 is the utility model sealing expansion chamber perspective view
Detailed description of the invention
According to the difference of workshop inleakage and new wind air output, differential pressure pickup reflects that workshop, side malleation value and workshop setting value compare, when malleation in workshop is higher than setting value, send and reduce to workshop air-supply instruction, make frequency conversion fan reduce rotating speed by frequency converter, realize reducing air quantity accordingly.Otherwise realize increasing air quantity.Workshop pressure reduction constant control is realized with this.
Claims (3)
1. a dust proof workshop forced draft system, this system comprises new wind expansion chamber, new wind frequency converter sets, differential pressure pickup.
2. a kind of dust proof workshop forced draft system as claimed in claim 1, it is characterized in that: comprise new wind and just imitate bag filter, new Windsock type Chinese style filter, negative-pressure type AD, it is characterized in that reducing the worry surface current speed of new wind by filter, decrease new wind running resistance, improve the dust containing capacity of filter, decrease during new wind filter uses the number of times that often need clean.
3. a kind of dust proof workshop forced draft system as claimed in claim 1, is characterized in that: frequency converter, differential pressure pickup control system, it is characterized in that controlling frequency converter by differential pressure pickup, regulates the air quantity of pressure fan.
