Abstract
The invention relates to a fire barrier for an anti-explosion internal-combustion engine. The fire barrier comprises a shell, wherein one end of the shell is provided with an air inlet which is communicated with a cylinder of the internal-combustion engine; the other end of the shell is provided with an air outlet which is connected with an air filter; the shell is internally provided with a fire barring core body; the fire barring core body comprises a support plate, fire barring layers and a plurality of fire barring plates; the support plate is fixed in the middle inside the shell and provided with air flow through holes; the fire barring layers are arranged at two side surfaces of the support plate; the plurality of fire barring plates are uniformly arranged at two sides of the support plate; and air channels are arranged between the fire barring plates. The fire barrier has the advantages of being strong in fire barring performance and high in safety factor.
Description
Technical field
The present invention relates to a kind of flame trap, relate in particular to a kind of explosion-proof internal-combustion engine and use flame trap.
Background technique
The occasion that has flammable explosive gas at petrochemical enterprise etc.; The internal-combustion engine of its use should possess explosion precaution; Wherein gas handling system needs special-purpose flame trap, prevents that the air blast in the cylinder of internal combustion engine from lighting peripheral flammable explosive gas, the existing old-fashioned wire fabric arrester that is still using; Though simple in structure, the back-fire relief poor-performing; New-type corrugated plate dst flame trap, the back-fire relief performance is good, but stainless steel wave card thermal conductivity is little, and thermal diffusivity is relatively poor, has limited the raising of back-fire relief performance.Therefore, need provide a kind of new technology to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide the explosion-proof internal-combustion engine that a kind of Fire retardance is strong, safety coefficient is high and use flame trap.
The technological scheme that the present invention adopts is:
A kind of explosion-proof internal-combustion engine is used flame trap, comprises housing, and said housing one end is provided with a suction port that is communicated with cylinder of internal combustion engine; The said housing the other end is provided with the air outlet, and said air outlet is connected with air-strainer, is provided with the back-fire relief core body in the said housing; Said back-fire relief core body comprises dunnage, flame retardant bed and a plurality of fire-proof plate; Said dunnage is fixed in the middle part in the housing, and said dunnage soil is provided with the air-flow through hole, and said flame retardant bed is located on the bi-side of dunnage; Said a plurality of fire-proof plate evenly is arranged at the both sides of dunnage, leaves air passageways between the said fire-proof plate.
In the middle of serving as reasons, said housing forms to the diminishing reducer pipe of two ends diameter; Said reducer pipe comprises horizontal segment, vertical section and tilting section; Said horizontal segment two ends are connected with vertical section is vertical respectively, and said vertical section lower end tilts to be connected with tilting section, and said tilt angle is 30-60 °.
Said fire-proof plate is 2-5.
Advantage of the present invention is: when burning, explosion phenomenon; Produce impact air-flow in the suction tude of cylinder of internal combustion engine; The dunnage that has the air-flow through hole obtains buffering with impact energy, leaves air passageways between the fire-proof plate, forces air blast to change airflow direction; Increase the cool time of explosive air-flow, the back-fire relief Safety performance is high.
