Abstract
This utility model discloses a positive-negative pressure ventilation type comprehensive microenvironment treatment system. The basic idea of a prevention and treatment method special for dust, harmful gas and noise pollution is that: fresh air is collected far away from polluted places and then conveyed to a microenvironment of a workplace and suitable pressure and flow rate of the fresh air are kept, so that dynamic sealing and dynamic separation to a pollution source are realized through the flowing air and pressure difference so as to maintain air in the microenvironment in a fresh state without being polluted. Specifically, three systems, including a tunnel-like small space system, a positive pressure system and a negative pressure system, are established. The tunnel-like small space system is beneficial to ventilation and air refreshing and beneficial to realization of dynamic sealing and dynamic separation to pollutants by the flowing air; the positive pressure system is capable of preventing the polluted air from entering a working environment by means of certain positive pressure and a certain flow rate; and the negative pressure system is capable of preventing the pollutants from leaking by adopting certain negative pressure and a certain flow rate. By adopting the design, the system is capable of creating a working environment with fresh air, no dust, no harmful gas and low noise in a large environment producing pollution so as to prevent occupational diseases. By adopting the design, the system is easy to implement in technology, adopts common materials, and is beneficial to popularization so as to realize environmental and social values.
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 have many kinds in the factory now, as the air inducing dedusting, and smoke evacuation, dust collecting sleeve dedusting, electric precipitation.But the pollutant of overflowing in the equipment can not be removed substantially, factory building is not only high but also big, and pollutant fills the air diffusion, can not all purify, the equipment that staff and generation are polluted is in the same space, can not change fresh air at any time again, in addition, also do not cause enough attention for noise pollution.In contaminated environment, work for a long time and caused various occupational diseases to take place.
Summary of the invention
Substantially administered in order to make working environment, the blocking-up dust, pernicious gas contacts with personnel, the prevention occupational disease, and technical scheme of the present invention is: isolate the little space of tunnel type in the big factory building of factory, personnel work in little space, one of little space is provided with air inlet, air inlet and pipeline UNICOM, pipeline and the air blast UNICOM that is located at the outer fresh air harvester of big factory building, the other end in little space is provided with air outlet, air outlet and big factory building UNICOM.Produce equipment and the operation polluted and also be isolated in the little space of tunnel type, one of little space is provided with air inlet, air inlet and big factory building UNICOM, and the other end in little space is provided with air outlet, air outlet and pipeline UNICOM, the air-introduced machine UNICOM of pipeline and treating apparatus.
Three systems 1 in this scheme, have been comprised, the little space system of tunnel type,---in the big factory building of factory, with workroom, the equipment room is isolated into little space as far as possible and long strip type is made in these little spaces, and type is like the tunnel, in order that minimizing cross-ventilation, be beneficial to the dynamic isolation to pollutant, dynamic seal (packing) is beneficial to the mobile replacing of air.
2, positive pressure system---gathering fresh air, by pipeline input service environment away from Polluted area.The little space of normal pressure pipeline UNICOM is an office, the lobby, and Control Rooms etc. are the personnel activity space here, its indoor door and window all will keep normal pressure, makes fresh air continuous in a steady stream, can stop contaminated air to enter again simultaneously, realizes 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, the little space of negative pressure system---negative pressure pipeline UNICOM is to produce the equipment that pollutes, and operation is as pulverizing ball milling, belt, packing etc.These the insides, little 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, this tunnel type space, just can get twice the result with half the effort ,-lift two to get.
Little space system can make multi-level in order that many-Dao defence line just many-part 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, and the pressure that shows as the workplace is higher than big factory building, and the pressure of big factory building is higher than equipment room.
Beneficial effect is, by ventilation type, and little space, positive negative pressure, multi-level, stepped isolation and sealing, the pollution of working environment can be administered substantially, prevents that occupational disease from taking place.
Description of drawings
Accompanying drawing is a schematic diagram: represented dynamic isolation, the realization mechanism 1 of dynamic seal (packing) is the fresh air harvester, the 2nd, and the normal pressure pipeline, the 3rd, the little space of tunnel type, the 4th, big factory building is the perisphere in little space, the 5th, the negative pressure pipeline, the 6th, 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 opening at two, little space ,-an air inlet ,-head is an air outlet.
The specific embodiment
In the accompanying drawings, fresh air harvester (1) design is away from pollution, the place that air is fresh, and coupling has the air blast of relevant pressure and flow.Normal pressure pipeline (2)-head and air blast UNICOM,-head and the little space of tunnel type normal pressure (3) UNICOM, effect is to working environment with fresh air conveying, because have-pressure and the flow of Ding stoped contaminated air to enter workplace, moving air is lower than workplace through the pressure that workplace arrives the big factory building of big factory building (4), be higher than equipment room, because equipment room is the little space of negative pressure, so have only the air of big factory building to flow into equipment room, the pollutant of equipment room, dust, pernicious gas can not be overflowed, and enter air-introduced machine with negative-pressure air-flow, enter treating apparatus.
Claims (4)
1. described positive negative pressure ventilation type subenvironment comprehensive treatment system, it is water spray dust, filter with dust collecting sleeve, air inducing dedusting smoke evacuation, it is characterized in that: in the big factory building of factory, isolate the little space of tunnel type, personnel work in little space, one of little space is provided with air inlet, air inlet and pipeline UNICOM, the air blast UNICOM of the air harvester that pipeline is outer with being located at big factory building, the other end in little space is provided with air outlet, air outlet and big factory building UNICOM, producing the equipment that pollutes also is isolated in the little space of tunnel type, one of little space is provided with air inlet, air inlet and big factory building UNICOM, and the other end in little space is provided with air outlet, air outlet and pipeline UNICOM, the air-introduced machine UNICOM of pipeline and treating apparatus.
