Description

Technical Field

[0001] This invention belongs to the field of fire extinguisher technology, and specifically relates to a special spray device for explosion suppression testing. Background Technology

[0002] In fire suppression and explosion suppression tests, determining the effectiveness of fire suppression and explosion suppression is a challenge. This invention is designed to verify the fire suppression and explosion suppression capabilities of fire extinguishing agents. During the test, the fire extinguishing agent is rapidly sprayed and reaches its fire suppression and explosion suppression capability within a specified time. The effectiveness of fire suppression and explosion suppression is then determined. The shorter the fire suppression and explosion suppression time, the better the effect. This device can quickly determine whether the fire suppression and explosion suppression effect meets the requirements for emergency use. Summary of the Invention

[0003] This invention consists of a dedicated nozzle (1), a bottle body (2), a valve seat (3), a valve (4), bolts (5), a fire extinguishing device 1 (6), a kerosene atomizing device (7), a fire extinguishing and explosion suppression test device (8), a fire extinguishing device 2 (9), and a jet direction (10). The nozzle is installed at the bottom of the fire extinguishing device, with the two fire extinguishing devices installed diagonally on the fire extinguishing and explosion suppression test device. The upper and lower installation positions are adjusted so that the nozzle and jet position are aligned. The kerosene atomizing device pre-fills the test device with atomized kerosene. When the high-temperature jet enters the test device at high speed, the system automatically captures the signal. The fire extinguishing device is activated quickly. The fire extinguishing agent will be accelerated towards the center of the test assembly through the Laval nozzle effect of the special nozzle (1). The fire extinguishing agent and the high temperature jet collide at the middle position of the test, which speeds up the filling of the test device and achieves the concentration of fire extinguishing and explosion suppression. The fire extinguishing agent concentration is the highest at the middle position, so that the fire extinguishing agent is quickly sprayed to the fire source position, suppressing the expansion of the fire source and extinguishing the fire in the first time. The fire extinguishing agent also has the function of cooling and reducing the concentration of kerosene, effectively preventing kerosene explosion and quickly covering the space that needs to be extinguished, so as to achieve the purpose of fire extinguishing and explosion suppression.

[0004] The fire suppression and explosion suppression capabilities are achieved within a specified time using a special spray device for explosion suppression testing. The effectiveness of the fire suppression and explosion suppression is judged based on the duration of the fire suppression and explosion suppression test. Attached Figure Description

Detailed Implementation

The nozzle is installed at the bottom of the fire extinguishing device, with the two fire extinguishing devices installed diagonally on the fire extinguishing and explosion suppression test device. The upper and lower installation positions are adjusted so that the nozzle and jet position are aligned. The kerosene atomizing device pre-fills the test device with atomized kerosene. When the high-temperature jet enters the test device at high speed, the system automatically captures the signal. The fire extinguishing device is activated quickly. The fire extinguishing agent will be accelerated towards the center of the test assembly through the Laval nozzle effect of the special nozzle (1). The fire extinguishing agent and the high temperature jet collide at the middle position of the test, which speeds up the filling of the test device and achieves the concentration of fire extinguishing and explosion suppression. The fire extinguishing agent concentration is the highest at the middle position, so that the fire extinguishing agent is quickly sprayed to the fire source position, suppressing the expansion of the fire source and extinguishing the fire in the first time. The fire extinguishing agent also has the function of cooling and reducing the concentration of kerosene, effectively preventing kerosene explosion and quickly covering the space that needs to be extinguished, so as to achieve the purpose of fire extinguishing and explosion suppression.

[0010] The fire suppression and explosion suppression capabilities are achieved within a specified time using a special spray device for explosion suppression testing. The effectiveness of the fire suppression and explosion suppression is judged based on the duration of the fire suppression and explosion suppression test.

Claims

1. A special spraying device for explosion suppression testing, characterized in that: It consists of a dedicated nozzle (1), a bottle body (2), a valve seat (3), a valve (4), a bolt (5), a fire extinguishing device 1 (6), a kerosene atomizing device (7), a fire extinguishing and explosion suppression test device (8), a fire extinguishing device 2 (9), and a jet direction (10). It is installed at the bottom of the fire extinguishing device. The two fire extinguishing devices are installed diagonally on the fire extinguishing and explosion suppression test device so that the nozzle is flush with the jet position. The kerosene atomizing device fills the test device with atomized kerosene in advance. When the high-temperature jet enters the test device at high speed, the system will automatically capture the signal and quickly start the fire extinguishing device. The extinguishing agent passes through the dedicated nozzle. (1) The Laval nozzle effect will accelerate the rush towards the center of the test assembly. The extinguishing agent and the high-temperature jet collide at the middle position of the test, which will speed up the filling speed of the test device and reach the concentration of extinguishing fire and suppressing explosion. This will allow the extinguishing agent to be sprayed quickly to the fire source position, suppress the expansion of the fire source and extinguish the fire in the first time. The extinguishing agent also has the function of cooling and reducing the concentration of kerosene, effectively preventing kerosene explosion and quickly covering the space that needs to be extinguished. Through the special spray device for the explosion suppression test, the extinguishing fire and suppressing explosion capability is achieved within a specified time. The extinguishing fire and suppressing explosion effect is judged according to the length of the extinguishing fire and suppressing explosion time.
