Abstract
A kind of positive/negative-pressure ventilation small-environment comprehensive treatment system.Particularly to dust, the prevention and controls basic conception of harmful gas and noise pollution is: gathering fresh air conveying in the subenvironment of site for labour and keep modest pressure and flow, realizing the dynamic seal (packing) to polluter and dynamic isolation with moving air and draught head away from the place polluted.Air to maintain subenvironment is fresh pollution-free.Specific practice is: build 3 systems, the little space system of (1) tunnel-type, and this design is conducive to air circulation and changes.Be conducive to realizing the dynamic seal (packing) to pollutant and dynamic isolation with moving air.(2) positive pressure system, utilizes certain normal pressure and flow to stop contaminated air to enter working environment.(3) negative pressure system, utilizes certain negative pressure and flow to keep pollutant not leak.The effect of the design is that to build air fresh in producing the overall situation polluted, without dust, without harmful gas, the working environment of low noise.To stop occupation disease generation.The design technically easily implements, and uses common material, is conducive to promoting, to realize environment and social value.
Description
Technical field
The present invention relates to the guard system of a kind of working environment and labour protection, particularly dust, harmful gas, and noise.
Background technology
To the safeguard procedures of dust and harmful gas it is in the factory now: the process device of dust arrester and harmful gas is set.But to polluter [producing equipment and the operation of pollutant] without effective method of controlling.Factory Building is not only high but also big, and Pollutants Diffusion is filled the air, it is impossible to all filter.Fresh air can not be changed again at any time.Working environment is among severe contamination.In addition. for noise pollution but without causing enough attention.Long-term work in contaminated environment result in the generation of various occupation disease.
Summary of the invention
Insight of the invention is that whole working environment carries out comprehensive control as a system whole factory.Dedusting, being used alone of preventer is waited to become serving a complete system.Desirable regulation effect is realized with existing equipment.Concrete grammar is: arranges the little space of tunnel-type, arranges fresh air conveying system.Air flowing and positive and negative air-pressure difference is utilized to realize the dynamic isolation to polluter；Dynamic seal (packing).Air is built fresh, without dust, without harmful gas, the subenvironment of low noise in producing the overall situation polluted.Stop the generation of occupation disease.
Accompanying drawing explanation
Accompanying drawing is schematic diagram: illustrate dynamic isolation, the realization mechanism of dynamic seal (packing).(1) it is fresh air harvester.(2) it is normal pressure pipeline.(3) it is the little space of tunnel-type. it is exactly the subenvironment to build of the present invention.(4) be big Factory Building it is bigger environment, is the perisphere of subenvironment.(5) it is negative pressure pipeline.(6) it is process and retracting device.The direction of arrow in pipeline represents air-flow direction.Sign symbol inside little space represents room pressure.
Detailed description of the invention
The specific embodiment of the invention is: build 3 systems.
1, it is the little space system of tunnel-type, in the big Factory Building of factory, by workroom, equipment room is isolated into little space as far as possible, and strip [likeness in form tunnel] is made in these little spaces in order that reducing cross-ventilation.The convenient dynamic isolation to pollutant, dynamic seal (packing).
2, positive pressure system, gather fresh air away from Polluted area, by pipeline input service environment.The little space of normal pressure pipeline communication is office, lobby, Control Room etc., is personnel activity space here, and it is indoor, and door and window will keep normal pressure, makes fresh air continuous in a steady stream, contaminated air can be stoped again to enter simultaneously.Realize subenvironment cleaning harmless.Before air supply duct enters room, it is introduced into air-conditioning, and air-conditioning combines and uses, and can regulate again temperature while keeping air fresh.
3, it is negative pressure system, the subenvironment of negative pressure pipeline communication is the equipment producing to pollute, operation, as pulverized, ball milling, belt, packaging etc..Negative pressure will be kept inside these spaces, and keep corresponding discharge, to ensure that contaminated air can all siphon away, and No leakage suction can process device, leak stopping pollutant.As long as installing puigging additional outside this tunnel-type space, just can get twice the result with half the effort, killing two birds with one stone.
Little space system can be made multi-level, in order that many one defence lines are with regard to bull point safety factor.
The pressure differential of positive/negative pressure system is stepped, shows as and successively decreases through several steps from positive pressure system to negative pressure system.
By little space, ventilation type, positive/negative-pressure, at many levels, stepped isolation and closing, the pollution of working environment can be administered substantially.Prevent occupation disease from occurring.
Claims (4)
1. a positive/negative-pressure ventilation type subenvironment comprehensive processing method, is a kind of method of pollution administration,
It is characterized in that: gather fresh air from away from the place polluted, being transported to continuously in working space, the air polluted is transported in process device simultaneously, concrete grammar is, isolating the little space of tunnel-type in the big Factory Building of factory, personnel work in little space；One of the little space at staff place and pipeline UNICOM, pipeline and be located at the air acquisition device UNICOM outside big Factory Building, other end and the big Factory Building in little space communicate: the equipment blocking producing to pollute is in other little space, one of little space additionally and big Factory Building communicate, little space and pipeline UNICOM, pipeline and process device UNICOM.
2. positive/negative-pressure ventilation type subenvironment comprehensive processing method according to claim 1, is characterized in that: step pneumatic is poor, and the pressure of workplace is higher than big Factory Building, and the pressure of big Factory Building is higher than equipment room, and equipment room is negative pressure.
3. positive/negative-pressure ventilation type subenvironment comprehensive processing method according to claim 1, is characterized in that: the space interval layer in the little space of tunnel-type and puigging combine.
4. positive/negative-pressure ventilation type subenvironment comprehensive processing method according to claim 1, is characterized in that: fresh air first passes through air-conditioning before entering workplace.
