Problems solved by technology

Due to insufficient attention to laboratory ventilation facilities, the construction units and personnel of laboratory ventilation facilities in various domestic research institutions have not reached the technical standard level, resulting in extremely low operating efficiency of ventilation facilities, which are useless
The interior of each laboratory is filled with polluted gas, which poses a great threat to the health of indoor personnel

Embodiment 1

[0022] The static pressure box 1 is arranged in the center of the indoor ceiling, and the static pressure box 1 is connected with the head air distribution device through the branch pipe 4 and the hose 6, and the branch pipe 4 can be freely extended. During the experiment, the fan 2 is running, and the outdoor fresh air is sucked in and supplied to the indoor personnel through the head air distribution device, so as to ensure the personal safety of the indoor experiment personnel. Experimenters can move freely in a small indoor area with the head air distribution device to achieve the purpose of convenient use.

[0023] The regulating valve 7 is used to adjust the air distribution volume of the air distribution device.

Embodiment 2

[0025] The static pressure box 1 is directly fixed on the upper part of the test bench, and the branch pipes 4 are evenly distributed around the static pressure box 1. The branch pipes 4 communicate with the head air distribution device through the hose 6, and the branch pipes 4 can be freely extended. Indoor personnel can use the head air distribution device nearby from all directions of the test bench. During the experiment, the fan 2 is running, and the outdoor fresh air is sucked in and supplied to the indoor personnel through the head air distribution device, so as to ensure the personal safety of the indoor experiment personnel.

[0026] The regulating valve 7 is used to adjust the air distribution volume of the air distribution device.

Embodiment 3

[0028] The outdoor air temperature is lower in winter, and the cold air can enter the static pressure box 1 after being heated up by the electric heating device 3, and the others are the same as in the embodiment 1.

Abstract

The invention discloses an individual protection system for a laboratory, consisting of an air inlet device and a head air distribution device, wherein the air inlet device consists of a static pressure chamber, a fan, an electric heating device and a ventilating pipeline, one end of the fan is communicated with the outdoor, the other end of the fan is connected with the static pressure chamber through the electric heating device, the static pressure chamber is connected with a branch pipe, the branch pipe is connected with the head air distribution device, the head air distribution device consists of a head fixing bracket and an air distribution device, the front segment of the head fixing bracket is a hollow pipe, the front end of the hollow pipe is fastened to the front part of a human jaw, a hanger hook is arranged at the rear segment of the hollow pipe, the hollow pipe is connected with the branch pipe through a sleeving flexible pipe, the air distribution device is composed of a branch air pipe and a transverse air distribution short pipe, one end of the branch air pipe is communicated with the head fixing bracket, and the other end of the branch air pipe is communicated with the transverse air distribution short pipe. The individual protection system disclosed by the invention is applicable to an indoor operator suffering from air pollution or pollution caused by part of particles, and enables indoor personnel to inhale fresh and clean air, the inhalation of polluted air is avoided, health of the operator is ensured, and the individual protection system is convenient to wear, and will not lead to cross pollution as respective components are not in contact with the mouth.

Description

technical field [0001] The invention relates to a laboratory personal protection system, in particular to a local air supply system for a human body. Background technique [0002] In various research departments and university laboratories, some pollution and harmful gases are often produced. The current method for removing indoor polluting gases is ventilation. The polluting gases are controlled in a certain space and discharged through various equipment. The main equipment includes airtight hoods, fume hoods, external suction hoods, and receiving hoods. Although all kinds of equipment have high efficiency, the actual construction and installation process requires high personnel quality and technical level. Due to insufficient attention to laboratory ventilation facilities, the construction units and personnel of laboratory ventilation facilities in domestic research institutions have not reached the technical standard level, resulting in extremely low operating efficiency...
