Abstract
The invention discloses a positive and negative pressure ventilation small-environment comprehensive treatment system, in particular to a method for preventing and controlling the pollution of dust, harmful gas and noise. The basic conception is that: fresh air is collected at a place away from pollution and then is conveyed to a small environment of a labor place and appropriate pressure and flow are kept, and dynamic sealing and isolation of the pollution source is realized by flowing air and air pressure so as to keep the air in the small environment fresh and pollution-free. The system is implemented by the following step of establishing three systems, namely (1) a tunnel-shaped small space system which contributes to air ventilation and replacement, and is favorable for dynamically sealing and isolating pollutant by using the flowing air, (2) a positive pressure system which prevents the polluted air from entering the working environment by using certain positive pressure and flow, and (3) a negative pressure system which keeps the pollutant from being leaked by using certain positive pressure and flow. The design has the advantages that: low-noise working environment in which air is fresh and dust and harmful gas are avoided is constructed in the large polluted environment, and occupational diseases are completely eradicated. The design is easy to implement technically, and a common material is used to facilitate popularization, so that environmental and social value is realized.
Description
Technical field
The present invention relates to a kind of working environment and labour protection, particularly dust, the guard system of pernicious gas and noise.
Background technology
The safeguard procedures to dust and pernicious gas are in the factory now: the treating apparatus that dust arrester and pernicious gas are set.But pollution sources [producing the equipment and the operation of pollutant] there is not effective method of controlling.Factory building is not only high but also big, and Pollutants Diffusion is filled the air, and can not all filter.Can not change fresh air at any time again.Working environment is among the severe contamination.Also do not cause enough attention for noise pollution in addition.Long-term work in contaminated environment caused the generation of various occupational diseases.
Summary of the invention
Design of the present invention is: whole factory, whole working environment carries out the comprehensive regulation as a system.Dedusting, wait the independent use of protector to become the complete system that serves.The regulation effect of realizing ideal with existing equipment.Concrete grammar is: the little space of tunnel shape is set, the fresh air conveying system is set.Utilize air to flow and the dynamic isolation of positive and negative air-pressure difference realization to pollution sources; Dynamic seal (packing).It is fresh to build air in producing the overall situation of polluting, no dust, no pernicious gas, the subenvironment of low noise.Stop the generation of occupational disease.
Description of drawings
Accompanying drawing is a schematic diagram: represented dynamic isolation, the realization mechanism of dynamic seal (packing).(1) is the fresh air harvester.(2) be the normal pressure pipeline.(3) be that the little space of tunnel shape is exactly the subenvironment that the present invention will build.(4) being that big factory building is bigger environment, is the perisphere of subenvironment.(5) be the negative pressure pipeline.(6) be to handle and retracting device.The ducted direction of arrow is represented air-flow direction.The sign symbol of the inside, little space is represented room pressure.
The specific embodiment
The specific embodiment of the invention is: make up 3 systems.
1, be the little space system of tunnel shape,---in the big factory building of factory, with workroom, the equipment room is isolated into little space as far as possible, and strip [likeness in form tunnel] is made in order that reduce cross-ventilation in these little spaces.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 that the normal pressure pipeline is communicated with is an office, the lobby, and Control Rooms etc. are the personnel activity space here, and it is indoor, and door and window all will keep normal pressure, makes fresh air continuous in a steady stream, can stop contaminated air to enter again simultaneously.Realize that the subenvironment cleaning is harmless.Before air supply duct enters the room, be introduced into air-conditioning and air-conditioning is used in combination, when keeping air fresh, can regulate temperature again.
3, be negative pressure system,---the subenvironment that the negative pressure pipeline is communicated with is to produce the equipment that pollutes, and operation is as pulverizing ball milling, belt, packing etc.These the insides, space all will keep negative pressure, and keep corresponding discharge, can all siphon away to guarantee contaminated air, and can not have the suction of leakage treating apparatus, leak to stop pollutant.As long as install puigging additional in outside, shape space, this tunnel, just can get twice the result with half the effort, kill two birds with one stone.
Little space system can be made multi-level, in order that many one defence lines are with regard to the bull point safety factor.
The pressure differential of positive/negative pressure system is stepped, shows as from the positive pressure system to the negative pressure system to successively decrease through several steps.
By little space, ventilation type, positive negative pressure, multi-level, stepped isolation and sealing, the pollution of working environment can be administered substantially.Prevent that occupational disease from taking place.
Claims (6)
1. utilize draught head to keep subenvironment not contaminated, described draught head is a ladder, the air pressure that shows as workplace [subenvironment] is higher than big factory building, and the air pressure of big factory building [overall situation] is higher than machine room, and the air pressure of machine room [subenvironment] is higher than the equipment that pollutes that produces.
2. utilize draught head to keep pollutant not leak, just the principle of negative pressure of equipment is not as [the negative pressure work design of Coal-disintegrating machine] for described negative pressure system, and main is machine room the inside, the negative pressure system in device external space.
3. the plant designing in the little space of tunnel shape, described little space are for avoiding cross-ventilation, prevent Pollutants Diffusion, the design of filling the air; Tunnel shape is to help the design that air flows and changes.Little space can be multi-level.
4. the collection of fresh air and conveying, the collection of described air and conveying are to become simple to air-polluting filtration, for filtering and replacing is worked along both lines.
5. carry the device of air to combine with air-conditioning, described conveying air and air-conditioning combination are to make to carry air and adjustment to realize synchronously.
6. space interval layer and puigging combination.Realize dust, pernicious gas, the comprehensive regulation of noise.
