Problems solved by technology

The higher air velocity will also increase the burning speed, reduce the fire extinguishing ability and the fire safety of the equipment
In addition, it is well known that the elongated grooves create a resistance, and the use of fire arresters with this resistance can provide high fire safety, while the important operational disadvantage of high pressure loss will also lead to fire arresters.
The existing anti-detonation equipment is not very safe, and some unexpected accidents often occur, which brings inevitable troubles to people's health and economy. Moreover, the existing anti-detonation flame arrestors have high requirements for flame arrestors. As a result, the production cost of the flame arrester remains high. The flame arrester core of the existing flame arrester often needs to be composed of fire arresting elements with different gap values. The function of the first layer of fire arresting elements is to resist the detonation pressure , the gap value is larger, the function of the second layer of fire retardant element is to block fire, and the gap value is smaller
The pressure drop caused by the gas passing through the flame arrester increases, which is not conducive to comprehensive promotion and application, and the production cost is extremely high

Embodiment Construction

[0016] like figure 1 , 2 As shown in , 3, the detonation type flame arrester includes shells 4, 20, flame arresters 3 and pipe joints 10, 21, and the shell 4 and the shell 20 are connected together by bolts, which is characterized in that: the shell 4 and the shell 20 There is a fire stop plate 3 between them, and buffer devices 1 and 5 are arranged between the pipe joints 10 and 21 and the fire stop plate 3 respectively. The edges of the buffer devices 1 and 5 are provided with a circle of through holes 2 and 6. There are microwave temperature control detectors 7 and 11 respectively on the upper part, the pipe joint 10 is connected in series with the cut-off valve 22 through the pipeline 9, and the cut-off valve 22 is connected with the temperature control receiver 8. The shape of the buffer devices 1 and 5 is bowl-shaped, The shape of the through holes 2 and 6 is circular. When in use, the flame 19 enters the expansion space formed between the buffer device 1 and the casin...

Abstract

The invention discloses a detonating type flame arrester, and belongs to the technical field of pipeline safety equipment. The detonating type flame arrester comprises shells, a flame arrester and a pipe joint, wherein the shells are connected through bolts; the detonating type flame arrester is characterized in that the flame arrester is arranged between the shells; a buffer device is arranged between the pipe joint and a flame arresting plate respectively; and a circle of through holes are formed in the edge of the buffer device. Because of the action of the buffer device, a requirement on the flame arresting plate is greatly reduced, so that production cost is reduced; and the flame arrester disclosed by the invention is beneficial for comprehensive utilization and application.

Description

technical field [0001] The invention relates to the technical field of pipeline safety equipment, in particular to a detonation type flame arrester. Background technique [0002] In the case of detonation, due to the superposition of the flame front and the excitation front generated by the explosion pressure wave, the flame propagation speed reaches several kilometers per second, and the combustion pressure in the impact direction may reach 100kpa in the upward direction. In the case of deflagration, the shock wave crosses the flame front, causing the deflagration flame propagation speed to reach hundreds of meters per second, and the combustion pressure in the direction of the shock reaches 10kpa in the upward direction, and the initial mixing pressure is 1kpa. A common approach is to attenuate or end the detonation by converting the detonation to deflagration before reaching the flame arrester. In many cases, the fire arrester is usually a combination of a detonation bra...
