Embodiment 1

[0024] An infinite air curtain blowing nozzle, which consists of: a base 2 and a gland 3 connected by screws 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 to The lower air jet curtain opening 7, the gland has an upper air jet curtain opening 8, the base is connected to the gland so that the upper air jet curtain opening and the lower air jet curtain opening form an air jet curtain opening 6.

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

[0026] This product is installed on the top and both sides of the e...

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that, as attached figure 1 , attached figure 2 As shown, in the described seamless air curtain blowing nozzle, an air inlet pipe 9 is installed in the air inlet pipe groove, and an air outlet hole 10 is opened at the upper end of the air inlet pipe, and the air outlet hole is located below the air outlet groove, and the air inlet pipe The air pipe is connected to the pneumatic valve 11.

Embodiment 3

[0030] The difference between this embodiment and Embodiment 1 is that, as attached figure 1 , attached figure 2 As shown, for the seamless air curtain blowing nozzle, the height of the air jet curtain opening is 0.03-0.05mm, and the air supply pressure of the air jet curtain opening is 0.4-0.6Mpa.

[0031] The height of the air jet curtain mouth is 0.03-0.05mm, and the air supply pressure is 0.4-0.6Mpa. Under this height and air supply pressure, the airflow ejected is relatively strong, which can completely cut off the harmful gas entering the rescue cabin and refuge chamber, making the rescue cabin And the refuge chamber has become a real life-saving space, ensuring the safety of the asylum seekers.

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 ...
