Abstract
The invention discloses a ventilating device. The ventilating device comprises an air supply fan, an air supply pipe, an exhaust fan and an exhaust pipe. The ventilating device is characterized by further comprising an air-supply static pressure box and an exhaust static pressure box, wherein an air outlet of the air supply fan is connected with an air inlet of the air-supply static pressure box by the air supply pipe; and an air outlet of the exhaust static pressure box is connected with an air inlet of the exhaust fan by the exhaust pipe. The ventilating device disclosed by the invention has the advantages that the structure is simple, the cost is low, the industrial pollution is controlled by utilizing air jetting, the control range of pollutants is large, the capture efficiency is high, the purposes of effectively controlling industrial pollution and protecting the occupational health are achieved, and simultaneously the energy is furthest saved.
Description
Technical field
The present invention relates to a kind of ventilation unit, specifically a kind of ventilation unit of controlling the industrial building indoor environmental pollution.
Background technology
Along with occupational health is protected the surging of cry, people more and more note the healthy of labourer, and, in industrial building, explained hereafter can produce a large amount of pollutants usually, in order to protect labourer's occupational health, and need to be to being ventilated between technique car.In prior art, in order to control the industrial building indoor environmental pollution, usually adopt local ventilation, near the pollution sources places, air-suction cover is being set, air-suction cover is connected with exhaust blower by airduct, and the swabbing action by exhaust blower sucks hood discharge by pollutant.This air-suction cover can only could be realized the control to polluting under closely near specified conditions such as pollution sources; but; actual field condition can not meet these regulations often; cause this class existing apparatus to lose the control to the industrial building indoor environmental pollution; make a large amount of Pollutants Diffusion of producing in art production process to workshop other zone or other workshop, and can't be effectively protected in the workman's of these regional works health.Air-suction cover is little except the pollutant control range, and the arresting efficiency of pollutant also exists ventilation large, the problems such as energy consumption height outside also relatively hanging down.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, and provide a kind of ventilation little, large to the pollutant control range, arresting efficiency is high, can effectively protect labourer's occupational health, again energy-conservation ventilation unit.
The inventor studies all the year round aeration technology and pollutant and controls, find to utilize blow, inspiratory flow realize to the Partial controll of pollutant more efficiently, more energy-conservation.Just look like to blow at a candle with mouth, be easy to just candle to be blown out, the air-blowing quantity needed also seldom, if still will extinguish candle with the air-breathing of mouth, needs take very large strength, can not extinguishing candles by very large inspiratory capacity.
The technical scheme that realizes the object of the invention is:
A kind of ventilation unit, comprise pressure fan, ajutage, exhaust blower and exhaust duct, unlike the prior art: also comprise air supply plenum chamber and air draft plenum chamber, the air outlet of pressure fan is connected with the air inlet of air supply plenum chamber by ajutage, and the air outlet of air draft plenum chamber is connected with the air inlet of exhaust blower by exhaust duct.
Be provided with the uniform flow orifice and the honeycombed orifice plate that are interconnected in described air supply plenum chamber, the honeycombed orifice plate is located at the air outlet of air supply plenum chamber.Uniform flow orifice is provided with equally distributed through hole, and aperture and the percent opening of through hole are decided according to the actual requirements.Uniform flow orifice and honeycombed orifice plate carry out rectification to the air that enters air supply plenum chamber, make the air-flow Uniform Flow.
The air inlet of described pressure fan and the exhaust outlet of exhaust blower are provided with the blinds adjusting device.
The inlet scoop of described air draft plenum chamber is provided with baffle plate, can reduce suction air volume.
During work, pressure fan sucks fresh air to enter air supply plenum chamber through ajutage from air inlet, uniform flow orifice in air supply plenum chamber carries out rectification to air, make the air-flow Uniform Flow, the honeycombed orifice plate of air supply plenum chamber air outlet is to the further rectification of air, make air-flow be similar to PARALLEL FLOW, arrive workspace, guarantee that labourer can breathe fresh air.Exhaust blower under swabbing action by the air-flow of suction with from air supply plenum chamber, parallel jet out forms continuous Push-pull Flow.After the pollutant produced in Push-pull Flow trapping production process, enter the air draft plenum chamber under the swabbing action of exhaust blower, through exhaust duct from the exhaust outlet discharge chamber.Air-supply and air exhausting device composition blow, the suction ventilation unit.
Advantage of the present invention is: simple in structure, cost is low, utilizes the industrial pollution of air-supply jet vectoring, and large to the pollutant control range, arresting efficiency is high, when reaching effective control industrial pollution and protection occupational health, has saved to greatest extent the energy.
