Embodiment Construction

[0021] refer to figure 1 , figure 2 , image 3 , a multi-fume hood control system proposed by the present invention includes: a plurality of fume hoods 1, an air detection device 2 corresponding to the fume hood 1, an air outlet pipe 3 and a control module.

[0022] A plurality of fume hoods 1 are scattered and installed indoors, and each fume hood 1 is equipped with a suction pump 4 . When the suction pump 4 is working, the air in the area where the fume hood 1 is located flows in from the air inlet of the fume hood 1 and is discharged from the air outlet of the fume hood 1 . The air outlets of each fume hood 1 are all communicated with the air outlet pipe 3, and the air outlet pipe 3 is used for exhausting outdoors, that is, the air flowing in from the air inlet of the fume hood 1 can be patted to the outside by the air outlet pipe 3.

[0023] In this embodiment, a plurality of fume hoods 1 are scattered and installed indoors, and the local air in which it is located can...

Abstract

The invention discloses a multi-ventilation-hood control system which comprises a plurality of ventilation hoods, air detection devices in one-to-one correspondence with the ventilation hoods, an air outlet pipe and a control module. The multiple ventilation hoods are installed indoors in a dispersed mode. Local air in the positions where the ventilation hoods are located can be exhausted through the ventilation hoods. In this way, when harmful matter appears in the local air, an air sucking pump in the corresponding ventilation hood can be started, and the local air containing the harmful matter is exhausted to the outside in time through the air outlet pipe, so that diffusion of the harmful matter in the local position is restrained, and the indoor air safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of laboratory ventilation control, in particular to a multi-fume hood control system. Background technique [0002] In laboratories and other occasions, it is necessary to ensure that the temperature, air pressure, wind speed and other parameters of the indoor or test operating platform are stable, and the test exhaust gas and waste heat can be removed in time. For this reason, the fume hood is a must-installed device. The fume hood is a relatively closed cabinet with a certain cavity space, a movable cabinet door is arranged in front of the cabinet, and an operating platform is arranged in the cabinet, so that the experimenter can use the platform after opening the cabinet door Engaged in various physical and chemical experiments. [0003] At present, in various laboratories, the control of fume hoods is too passive, resulting in low efficiency of fume hoods, resulting in waste of energy and increasing the...
