Background

In industrial production occasions, a pipeline with small and medium diameters, which can leak and generate smoke, gas and fog, often leaks at one point or a plurality of points, thereby bringing about potential safety hazards. Therefore, it is necessary to provide an air suction device in a pipe where there is a possibility of leakage and generation of smoke, gas, or mist, and to dispose of the leaked gas in time.

The traditional suction and exhaust hood can be divided into two types of suspended type and non-suspended type according to the suspension mode, the suspended suction hood is usually designed into a cone top type structure, the cone top type structure has relatively high rigidity and relatively dispersed suspension points, so a relatively light metal frame can be selected during design, but the structure has strict requirements on a top floor, and the structure cannot be used when the site space of a user and the civil engineering load are limited. The suspended air suction and exhaust cover can also block the traffic of a workshop, the air suction and exhaust cover needs to be completely removed before the overhaul of the equipment every time, the overhaul operation is very complicated, and the market acceptance of the suspended air suction and exhaust cover is low.

Therefore, modern industry prefers a non-hanging suction hood. The non-hanging air suction cover is supported on the operation floor by a plurality of support legs, no hanging point is designed on the top floor, a layer of metal thin plate or plastic plate is adopted as a top panel, the metal thin plate or the plastic plate cannot be directly and independently used as the top panel due to poor rigidity, and a large number of metal grids are required to be designed at the bottom of the metal thin plate or the plastic plate for supporting. Therefore, the design requires more metal materials, and has heavy weight and high cost. While the metal frame is more susceptible to corrosion by acid gases. When the area of the air suction and exhaust hood is large, the self weight of the steel grating sometimes generates large deflection at the central position, and the design requirement is difficult to meet.
