Abstract
The utility model discloses a flame arrester which is characterized by comprising two tubular butt joint pieces, wherein a fire arresting ring is arranged at the butt joint end of the two butt joint pieces, two annular lugs are arranged on the fire arresting ring in the peripheral direction, and stepped groove parts used as mounting positions of the fire arresting ring are arranged at the inner side of the annular lugs. The flame arrester has the beneficial effects that (1) the structure is simple, the mounting is convenient, excessive area is not occupied, and the flame arrester can carry out effective fire arresting to methane and is safe and reliable; and (2) the flame arrester is corrosion resistant and deflagration preventing.
Description
Technical field
The utility model relates to a kind of 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.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and a kind of spark arrester is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of spark arrester is characterized in that, comprising:
Two tubular interfacing parts, the butt end of two interfacing parts is provided with the back-fire relief ring, and said back-fire relief ring circumferentially is provided with two annular ears outward, and this annular ear inboard has the step-like concave part as back-fire relief ring installation position.
Preferably, said two annular ears have at least two annular seal grooves in a side end face in opposite directions.
Preferably, said two annular ear contact end faces are provided with seal, and the sealing part has is located at the protuberance consistent with the annular seal groove flute profile.
Preferably, said two annular ears a plurality of bolts hole that are circular layout, two annular ears connect through bolt.
The beneficial effect of the utility model is:
(1), simple in structure, easy for installation, do not take too much area, can carry out effective back-fire relief to biogas and handle, safe and reliable;
(2) corrosion-resistant, anti-detonation.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-5, a kind of spark arrester, it comprises: two tubular interfacing part 1a; 1b, the non-butt end that the butt end of two interfacing parts is provided with back-fire relief ring 5, two interfacing parts is respectively as air inlet/outlet and be provided with ring flange 8; Said back-fire relief ring circumferentially is provided with the two annular 9a of ear outward, 9b, and annular ear is the metal finish part; And use as compressing member, this annular ear inboard has the step-like concave part 90 as back-fire relief ring installation position, changes the traditional standard flange connection with this; Performance is more stable, and can bear high temperature, corrosion-resistant, explosion arrestment combustion, can satisfy the needs of demands of different.
The step-like concave part of the interface of said annular ear and interfacing part, back-fire relief ring and annular ear is equipped with sealing device and seals.
Said two an annular ears side end face in opposite directions have two annular seal grooves 3, and said two annular ear contact end faces are provided with seal 6, and the sealing part has is located at the protuberance consistent with the annular seal groove flute profile, and this case seal groove flute profile is a triangle, and protuberance matees therewith.
A plurality of bolt hole 7, the two annular ears that are circular layout of said two annular ears are fixedly connected through bolt 4.
Spark arrester is to prevent that external flame from scurrying in the equipment that has flammable explosive gas, the pipeline or the equipment that stops flame to spread at equipment, pipeline enclosure, when spark arrester is used the small gap of flame through heat conductor, and the principle manufacturing of extinguishing owing to thermal loss.
The back-fire relief ring of this spark arrester adopts the double-level-metal screen net structure; And annular ear is provided with the seal groove fit seal passage of interfacing part is sealed; Enlarge the contact area of tiny flame and conduit wall, the collision probability of flame and woven wire heightens, and has strengthened heat-transfer effect; Flame temperature is reduced to below the ignition temperature rapidly, thereby flame can't be scurried into.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection domain that also should be regarded as the utility model.
