Abstract
The utility model discloses a marsh gas flame arrester which comprises an upper shell and a lower shell, wherein a middle flame-arresting pipe is arranged between the upper shell and the lower shell; the upper shell is provided with a gas inlet; the lower shell is provided with a gas outlet; the gas inlet is provided with a sealing plate; a flame-arresting wall is arranged in the middle flame-arresting pipe; a groove is formed in the flame-arresting wall; the bottom of the sealing plate is connected with one end of a draw rod; the other end of the draw rod is arranged in the groove; the middle of the draw rod is connected with a pressure rod; the pressure rod is connected with a handle outside the upper shell; the middle flame-arresting pipe is divided into two flame-arresting chambers by the flame-arresting wall; and a flame-arresting core is arranged in each flame-arresting chamber. According to the utility model, the middle flame-arresting pipe is divided into the two flame-arresting chambers by the flame-arresting wall, so that marsh gas of a high flow rate can be separately subjected to flame-arresting operation, thus reducing the flame-arresting pressure and achieving favorable effect; and the gas inlet is provided with the sealing plate, and the sealing plate can be vertically moved in the groove by the draw rod to open or close the gas inlet, thus achieving high flexibility.
Description
Technical field
The utility model relates to a kind of spark arrester, relates in particular to a kind of biogas spark arrester.
Background technology
Existing biogas spark arrester utilizes wavy metal dish slit gap that flame is had the extinguishing action principle to manufacture and design, adopt standard flange to connect, safety coefficient and back-fire relief poor performance, and back-fire relief performance reliability big for the biogas flow, when pressure is big is low.Therefore, need provide a kind of new technology to solve the problems referred to above.
The utility model content
The purpose of this utility model provides the good biogas spark arrester of a kind of back-fire relief performance.
The technical solution adopted in the utility model is:
The biogas spark arrester, comprise upper shell and lower house, back-fire relief pipe in the middle of being provided with between described upper shell and the lower house, have air inlet on the described upper shell, have the gas outlet on the described lower house, described air inlet place is provided with sealing plate, be provided with a fire resisting wall in the back-fire relief pipe in the middle of described, have a groove in the described fire resisting wall, described sealing plate bottom is connected with pull bar one end, and the described pull bar other end is located in the groove, be connected with depression bar in the middle of the described pull bar, described depression bar is connected with upper shell handle outward, and described fire resisting wall is divided into two back-fire relief chambeies with middle back-fire relief pipe, has fire-retardant core in each back-fire relief chamber.
Described fire-retardant core top and bottom are equipped with steel wire.
Back-fire relief pipe both sides are provided with access hole in the middle of described.
Described fire-retardant core is overlapping corrugated plating.
The utility model has the advantages that: fire resisting wall is divided into two back-fire relief chambeies with middle back-fire relief pipe, big flow biogas can be separated back-fire relief like this, reduces back-fire relief pressure, effective, the air inlet place is provided with sealing plate, and sealing plate can move up and down in groove by pull bar, open or close air inlet, flexibility height.
