Example Embodiment

[0023] Example one

[0024] An endless air curtain blowing nozzle, which is composed of: a base 2 and a gland 3 connected by a screw 1, the base is provided with an air inlet pipe groove 4, the air inlet pipe groove is connected to an air outlet groove 5, and the air outlet groove is connected The lower air jet screen opening 7 has an upper air jet screen opening 8 on the gland, and the base is connected with the gland so that the upper air jet screen opening and the lower air jet screen opening form an air jet screen opening 6.

[0025] It is mainly used for the aerosol blowing of the refuge chamber door when the compressed air is sprayed through the 0.03-0.05mm air jet screen port to form a dense, continuous and uninterrupted air curtain, which can effectively block the intrusion of harmful gases in all directions. To isolate and shield the role of strong purge positive pressure control.

[0026] This product is installed above and on both sides of the explosion-proof door of ...

Example Embodiment

[0027] Example two

[0028] The difference between this embodiment and the first embodiment lies in the following: figure 1 , Attached figure 2 As shown, in the endless air curtain blowing nozzle, the inlet pipe groove is equipped with an inlet pipe 9, and the upper end of the inlet pipe is provided with an outlet hole 10, and the outlet hole is located below the outlet groove, and the inlet The air pipe is connected to the pneumatic valve 11.

Example Embodiment

[0029] Example three

[0030] The difference between this embodiment and the first embodiment lies in the following: figure 1 , Attached figure 2 As shown, for the endless air curtain mouthpiece, the height of the air jet screen mouth is 0.03-0.05 mm, and the air supply pressure of the air jet curtain mouth is 0.4-0.6Mpa.

[0031] The height of the jet screen opening is 0.03-0.05mm and the air supply pressure is 0.4-0.6Mpa. At this height and the air supply pressure, the airflow sprayed out is relatively strong, which can completely cut off harmful gases entering the rescue cabin and refuge chamber, and make the rescue cabin And the refuge chamber becomes a real life-saving space, ensuring the safety of the asylum.

Abstract

The invention relates to a gapless air curtain blow nozzle and an air blowing method. The air outlet hole of the existing air curtain blowing and flushing pipe is the circular hole, the spraying area for air blowing is very small and belongs to the dot spraying, and the harmful gas cannot be completely blocked from entering, so the air purity in the escape capsule and the refuge chamber cannot be ensured, and the safety of refugees cannot be ensured. The gapless air curtain blow nozzle consists of a base (2) and a press cover (3), wherein the base (2) and the press cover (3) are connected through a screw (1), the base is provided with an air inlet pipe groove (4), the air inlet pipe groove is connected with an air outlet groove (5), the air outlet groove is connected with a lower air spraying curtain port (7), the press cover is provided with an upper air spraying curtain port (8), the base is connected with the press cover, and the upper air spraying curtain port and the lower air spraying curtain port form an air spraying curtain port (6). The gapless air curtain blow nozzle is used for blocking the harmful air from entering the refugee chamber.

Description

technical field [0001] The invention relates to an endless air curtain blowing nozzle and a blowing method. Background technique [0002] The air outlet hole of the existing air curtain purge pipe is a round hole, and the spray area of ​​the blown gas is small, which belongs to point spray, which cannot completely prevent the entry of harmful gas, and cannot guarantee the safety of the air in the rescue cabin and refuge chamber. Purity cannot guarantee the safety of refugees. Contents of the invention [0003] The object of the present invention is to provide an air-curtain-shaped injection gas, an endless air-curtain blowing nozzle and a blowing method that can completely prevent the harmful gas from entering. [0004] Said purpose is achieved by the following scheme: [0005] An infinite air curtain blowing nozzle, which consists of: a base and a gland connected by screws, the base is provided with an air inlet pipe groove, the air inlet pipe groove is connected to an ...
