Abstract
The utility model discloses a special flame arrester for a pipeline, which comprises an inner shell and an outer shell, wherein both ends of the inner shell and the outer shell are provided with flanges; a flame-arresting core is arranged in the inner shell; steel wire tapes are arranged at the upper end and the lower end of the flame-arresting core in the inner shell; the left side and the right side of the flame-arresting core are respectively provided with a positioning ring and a fixing ring; lateral partition plates are respectively arranged between the flame-arresting core and the positioning ring as well as between the flame-arresting core and the fixing ring; the upper part of one end of the outer shell and the lower part of the other end of the outer shell are provided with heat tracing medium inlets/outlets. According to the utility model, the steel wire tapes are arranged at the upper end and the lower end of the flame-arresting core in the inner shell, and the lateral partition plates are arranged at the left end and the right end of the flame-arresting core, so that the fluid flame-arresting capability is low, high-speed flame can be arrested by flame-arresting steel balls, blockage can not be caused easily, and the flame-arresting property is favorable.
Description
Technical field
The utility model relates to a kind of spark arrester, relates in particular to the special-purpose spark arrester of a kind of pipeline.
Background technology
The spark arrester of using always is made by wire netting at present, and the number of plies of wire netting and mesh order number are directly connected to the back-fire relief performance.The spark arrester convection cell back-fire relief power of this structure is big, and easily stops up, and the back-fire relief performance is also poor, only is suitable for stoping low speed flame.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 special-purpose spark arrester of the good pipeline of a kind of back-fire relief performance.
The technical solution adopted in the utility model is:
The special-purpose spark arrester of pipeline, this spark arrester comprises inner casing and shell, the two ends of described inner casing and shell are provided with ring flange, has fire-retardant core in the described inner casing, be provided with pierce tap in the inner casing at two ends about the described fire-retardant core, the described fire-retardant core left and right sides is respectively equipped with locating ring and retainer ring, is equipped with the side dividing plate between described fire-retardant core and the locating ring and between fire-retardant core and the retainer ring, and described shell one end top and shell other end bottom all have companion's thermal medium gateway.
Described fire-retardant core is the back-fire relief steel ball.
Described pierce tap has triangular groove.
Described dividing plate forms by wire netting is overlapping.
The utility model has the advantages that: be provided with pierce tap in the inner casing at two ends about the fire-retardant core, two ends, the fire-retardant core left and right sides also have the side dividing plate, and convection cell back-fire relief power is little, and the back-fire relief steel ball can stop high-speed flame, are difficult for stopping up, and the back-fire relief performance is good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, inner casing, 2, shell, 3, ring flange, 4, fire-retardant core, 5, pierce tap, 6, locating ring, 7, retainer ring, 8, the side dividing plate, 9, companion's thermal medium gateway.
The specific embodiment
As shown in Figure 1, the special-purpose spark arrester of pipeline of the present utility model, this spark arrester comprises inner casing 1 and shell 2, the two ends of inner casing 1 and shell 2 are provided with ring flange 3, have fire-retardant core 4 in the inner casing 1, be provided with pierce tap 5 in the inner casing 1 at fire-retardant core two ends about in the of 4, fire-retardant core 4 left and right sides are respectively equipped with locating ring 6 and retainer ring 7, be equipped with side dividing plate 8 between fire-retardant core 4 and the locating ring 6 and between fire-retardant core 4 and the retainer ring 7, shell 2 one end tops and shell 2 other end bottoms all have companion's thermal medium gateway 9.
Fire-retardant core 4 is the back-fire relief steel ball, and pierce tap 5 has triangular groove, and side dividing plate 8 forms by wire netting is overlapping.
Be provided with pierce tap 5 in the inner casing 1 at fire-retardant core two ends about in the of 4, two ends, fire-retardant core 4 left and right sides also have side dividing plate 8, and convection cell back-fire relief power is little, and the back-fire relief steel ball can stop high-speed flame, are difficult for stopping up, and the back-fire relief performance is good.
