Most importantly degassing function in the function of vent cabinet; in chemical laboratory; can produce various pernicious gases, foul smell, moisture and inflammable, explosive, corrosive substance during experimental implementation; in order to protect user's safety; polluter in preventing to test spreads to the laboratory; will use vent cabinet near pollution sources, it is less that vent cabinet uses the platform number in the past, only at harmful and dangerous especially gas and produce in the experiment of big calorimetric and use.Therefore, traditional vent cabinet is generally only undertaken the miscellaneous function of experimental bench.
Consider in recent years and improve laboratory environment, improve labour health condition, increase work efficiency, the experiment of carrying out on experimental bench is transferred in the vent cabinet gradually, therefore the use platform number of vent cabinet increases at a gallop, but being huge ventilation, thing followed problem cause in the laboratory negative pressure very big, need be from outdoor a large amount of benefit wind (window need be opened), but this brings following problems: 1, at present, all there is air-conditioning system in newly-built laboratory mostly, but the use of a large amount of vent cabinets is taken indoor cold air or heating installation rapidly away, cause the huge waste of the energy, the laboratory electricity charge are significantly risen; 2, window makes outdoor air enter the laboratory in a large number with the door open, brings a large amount of dusts to influence the clean environment of Laboratory Request, particularly very high to environmental requirement laboratory; 3, huge exhausting air quantity makes between the laboratory easily and collaborates, and produces certain influence for some special test meetings.For this reason, the benefit wind vent cabinet that is provided with in order to reduce negative pressure has appearred in the market, but this vent cabinet has only solved the benefit wind problem of single ventilation cabinet, and purpose is merely to solve negative pressure to mend the wind problem, rather than the problem of above three aspects of solution, it need increase breeze fan, has increased power consumption, and the wind-supplying mouth position is arranged on front end can cause that reflux gas overflows, influences putting of experimenter's operation and article.
The utility model content
The purpose of this utility model is to provide a kind of novel ventilated cabinet device that is used for the physics and chemistry testing environment, and it can overcome above-mentioned defective, does not need to increase breeze fan again, can realize the recycling of air, does not increase energy consumption.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopted is:
A kind of novel ventilated cabinet device that is used for the physics and chemistry testing environment, it comprises: vent cabinet, air draft pipe and exhausting motor, wherein, it also further includes environment-friendly processing unit and return air duct, described environment-friendly processing unit links to each other with described exhausting motor, described environmental protecting device is provided with air discharge ports, and described air discharge ports links to each other with the wind-supplying mouth of described vent cabinet by described return air duct.
The above-mentioned novel ventilated cabinet device that is used for the physics and chemistry testing environment, it also further comprises Electric air valve, this Electric air valve is located at the correspondence position of described air discharge ports.
The above-mentioned novel ventilated cabinet device that is used for the physics and chemistry testing environment, it also further includes the treating apparatus again that dehumidifies, and described return air duct comprises two sections, one end of first section return air duct link to each other with described air discharge ports first section return air duct the other end and described dehumidifying again treating apparatus link to each other, one end of second section return air duct and described dehumidifying treating apparatus again link to each other, and the other end of second section return air duct links to each other with the wind-supplying mouth of described vent cabinet.
Preferably, the wind-supplying mouth of above-mentioned vent cabinet is arranged on the rear end of described vent cabinet table top.
Preferably, above-mentioned vent cabinet includes locker, operating table surface and sliding glass, and described locker is located at described vent cabinet bottom, and described operating table surface is located on the locker, and described sliding glass is located at the middle part of vent cabinet.
Preferably, the rear end of the table top of above-mentioned vent cabinet also is provided with deflector.
After adopting said structure, during use, vent cabinet is extracted into waste gas in the environment-friendly processing unit by the exhausting motor behind combustion gas, treated waste gas, discharge by the air discharge ports of environment-friendly processing unit again, get back in the vent cabinet by return air duct, this novel product promptly allows the experimenter avoid the influence of chemistry or physics harm in experimental implementation except reaching the function of common vent cabinet system, ensure beyond the safety and health of lab assistant, can also play effectively energy-conservation effect.This circulating energy-saving type vent cabinet system can be used in general physical and chemical experiment chamber, consider and to use for bio-safety for biocontainment laboratory will consider whether be suitable for according to situations such as the kind of discharging waste gas and environmental protection treatment effects for the laboratory of other specific use.Specifically, compared with the existing, its advantage is as follows:
1) only needs disposable installation return air duct system and use to mend the wind vent cabinet, do not need to increase again breeze fan, only utilize original air exhauster just to realize the recycling of air, do not increase energy consumption;
2) pass through the recycling of most of air (80%), played the benefit wind action, greatly reduced the amount that cold air or heating installation are taken away, energy-saving effect is very obvious;
3) because air recycling, the door that do not need to window greatly can be mended wind, has significantly reduced the inflow of laboratory outer air, and breadboard clean environment can be kept better, also can not produce the problem of collaborating in the laboratory.
4) because experiment waste gas is in the circulating treating system near sealing substantially,, protected environment better near the zero-emission that has realized waste gas.
