Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 , A drawer-type flame arrester of the present invention is mainly composed of a housing 3, a fire arresting element 4, an interlayer filler 5, an upper and a lower pressure ring 6, a gland 8 and screws 9.

[0029] The housing 3 has a rectangular base. The housing 3 is provided with a drawer-shaped cavity. The upper and lower parts of the housing 3 are provided with inlets and outlets. The edge of the drawer opening on the side of the housing 3 is provided with protrusions for easy assembly.

[0030] The fire arresting element 4 is composed of several sheets and placed in the cavity of the housing 3 . In the middle layer of the fire retardant element 4, a rectangular interlayer filler 5 is arranged. The interlayer filler 5 is designed as a perforated mesh plate, which is evenly stressed and stable, and is not easily deformed by the...

Abstract

The invention relates to a drawer-type flame arrester, comprising a housing, a fire resistant component, barrier filler material, upper and lower press rings, a gland and screws, wherein, the housing is provided with a rectangular base and a drawer-type cavity, the upper portion and lower portion of the housing are both provided with inlets and outlets, the edge of the opening of the drawer arranged at the side portion of the housing is provided with a bulge; the fire resistant component comprises a plurality of sheet materials and is arranged in the cavity of the housing, the interlayer of the fire resistant component is provided with rectangular barrier filler materials, and the top and the bottom of the fire resistant component are provided with the upper and lower press rings; the glands are arranged on the edge of the housing and fixed on the bulge which is arranged on the edge of the housing with the screws; and reducers are arranged at the inlets and outlets of the housing, andthe end portions of the reducers are provided with flanges. According to the invention, the fire resistant component, the barrier filler materials and the upper and lower press rings are fixed as a whole with countersunk head screws, so that the problem of blockage of holes is solved, the materials are saved half, and when repairing and replacing the fire resistant component, the online cleaning,replacing the other work can be realized with only removing the screws to take the fire resistant component out.

Description

technical field [0001] The invention relates to equipment and pipelines for storing flammable and explosive gases, in particular to an improved drawer-type flame arrester. Background technique [0002] The flame arrester is a component that prevents external flames from entering into equipment and pipelines containing flammable and explosive gases, or prevents flames from spreading in equipment or pipelines. Flame arresters are generally designed based on the principle that flames are extinguished due to heat loss when they pass through a small gap in a heat conductor. Flame arresters play a pivotal role in the petrochemical industry. [0003] The flame arresters currently used in the petrochemical industry have the following shortcomings: [0004] 1. The thickness of the fire retardant element is generally 20mm, and the flow hole is easily blocked. [0005] 2. The interlayer filler is a bilateral triangular member made of φ6.3mm round steel, which is unevenly stressed, p...
