Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the staff with ordinary skill in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides an energy-conserving ventilation system in laboratory, is including setting up air exit 6 at the indoor top of laboratory, the exhaust pipe of air exit 6, universal gas collecting channel all links to each other with exhaust pipe 7, exhaust pipe 7's the other end is connected to purifier's air inlet end, purifier sets up outside the laboratory, and purifier's air-out end links to each other with intake stack 12, intake stack 12 links to each other with the air intake 13 that sets up bottom in the laboratory.

In this embodiment, the purification device includes a purification device casing, one end of the purification device casing is provided with an air outlet, the other end is provided with an air inlet, inside the purification device casing near one end of the air inlet, a first filter 8 and a second filter 10 are sequentially arranged, a VOC detector 9 and an acid gas sensor 19 are arranged between the first filter 8 and the second filter 10, and inside the purification device casing near one end of the air outlet, a fan 11 is arranged.

In this embodiment, the first filter 8 and the second filter 10 are the same high efficiency filter.

In this embodiment, an air supply port is further disposed between the second filter 10 and the fan 11 of the purification apparatus, the air supply port is connected to an air supply pipeline 17, and an air supply valve 15 and a primary filter 16 are disposed on the air supply pipeline 17.

In this embodiment, laboratory inside still disposes air curtain formula fume chamber 1, be connected with fume chamber air supplement pipeline 2 and fume chamber exhaust pipe 3 on the air curtain formula fume chamber 1, fume chamber exhaust pipe 2 links to each other with the fan 4 of airing exhaust that sets up in the laboratory outside.

In this embodiment, a test bed, a universal gas-collecting hood 14, and an atomic absorption hood 18 are also disposed in the laboratory.

The specific working process is as follows:

when the device works, the fan 11 of the purification device is started, at the moment, gas polluted by slight tests, reagent evaporation and the like in a laboratory enters the purification device through the exhaust outlet 6 and the exhaust pipeline, and firstly enters the first filter 8, and the first filter 8 can simultaneously process chemical reagents such as organic solvents, acids, alkalis and the like in the gas; the gas treated by the first filter 8 passes through the VOC sensor 9 and the acid gas sensor 19, and the VOC sensor 9 and the acid gas sensor 19 can detect the concentration of toxic and harmful gases in the air at the moment; if the gas quality reaches the standard, the purified gas returns to the laboratory from the air inlet 13 through the fan 11 and the air inlet pipeline 12; if the gas quality does not reach the standard, the tail gas is filtered by the second filter 10, passes through the fan 11 and the air inlet pipeline 12, and returns to the laboratory through the air inlet 13. The VOC sensor 9 and the acid gas sensor 19 adopt the prior art, and the indexes of the VOC sensor 9 and the acid gas sensor 19 can be generally adjusted according to the needs of users. The first filter 8 and the second filter 10 serve as a double guarantee to prevent harmful gases from re-entering the laboratory.

In this embodiment, when the VOC sensor 9 and the acid gas sensor 19 detect that harmful gas in the gas exceeds a certain threshold, the alarm is triggered to send an alarm to remind laboratory personnel to replace the purification device in time; laboratory personnel may remove the purification device when the environmental venting system is not in operation, remove and install the second filter 10 at the first filter 8, and replace the new filter at the second filter 10.

Because a small amount of indoor gas can be discharged by equipment such as the air curtain type fume hood 1 and the like during normal work, the gas in the laboratory is slightly lost, and a proper amount of air supplement needs to be carried out from the outside.

When needing to mend the wind, can mend the wind through mending wind pipeline 17: at fume chamber air supply pipeline 2, can set up air sensor in fume chamber exhaust pipe 3 and the air supply pipeline 17, at air curtain formula fume chamber 1 normal during operation, according to the air volume value difference that the air sensor on fume chamber air supply pipeline 2 and the fume chamber exhaust pipe 3 detected, the system can calculate the amount of wind that needs to be mended, the degree of opening of air valve 15 is controlled according to the air volume value that air sensor detected on air supply pipeline 17 this moment, gas can enter into purifier through air supply pipeline 17, primary filter 16 can filter the gas of replenishment, then pass through fan 11, intake stack 12, enter into the laboratory by air intake 13, can replenish indoor air.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the claimed invention.
