Super-large-span all-glass-fiber-reinforced-plastic deodorization cover plate and odor collection device

Abstract

The invention provides a super-large-span all-glass-fiber-reinforced-plastic deodorization cover plate. The cover plate is made of high-strength glass fiber reinforced plastic which is not supported by a metal framework, and is characterized in that the cross section of the cover plate is in a large-span arch shape, the longitudinal section of the cover plate is in a continuous small-span arch shape, the cover plate is formed by connecting a plurality of cover plate units, each cover plate unit comprises two semi-arch side wings positioned on the two sides, a pedestrian path is formed a sunkenpart between the two semi-arch side wings of each cover plate unit, the outer side ends of the two semi-arch side wings of each cover plate unit are provided with connecting flanges correspondingly,the connecting flanges are located at the tops of the semi-arch side wings, the two adjacent cover plate units are connected through the connecting flanges, and the connected flanges form a longitudinal reinforcing rib positioned outside the cover plate. A connecting position of the cover plate units of the cover plate is located at the top of each small-span arch shape, after the cover plate units are connected through the flanges, the flange edges form one longitudinal reinforcing rib located outside the cover plate, sealing is achieved, meanwhile, the longitudinal strength of the cover plate is further enhanced, and the span of the cover plate can be improved.

Description

technical field [0001] The invention relates to the technical field of odor collection, in particular to a frameless large-span low-clearance deodorizing cover plate and an odor collection device. Background technique [0002] At present, traditional odor collection devices generally use anti-hanging fiber membranes, glass fiber reinforced plastic single arch panels with steel pipe skeletons, and Kapron panels lined with stainless steel frames, etc., which have many disadvantages; for example: anti-hanging fiber membranes need to be used as supporting steel frames , its weight is heavy, and some of the built sewage pools cannot bear its weight, the headroom is high, the deodorization air volume is large, people work inside, the environment is harsh, and it is easy to form a collection dead angle; Cracking occurs and the life is short; the stainless steel components of the lined stainless steel frame will be corroded if they are exposed to the environment with high odor conce...

Problems solved by technology

[0005] 1. Although the cover plate has high strength, the upper part can be operated and repaired by the upper part, but in order to maintain the strength, the cover plate is connected by two larger continuous arched components with a longitudinal section of several integral ones. It needs to be processed and transported like this Huge components are not easy

[0006] 2. The connection of the two cover plates is flat, which destroys the double-arch overall load-bearing structure and limits the further expansion of the span

[0009] 1. The connection seams between the cover plates are located at the bottom of both sides of the small arc of the cover plates, and the joints cannot bear the pressure in the direction perpendicular to the cover plates. Therefore, personnel cannot move on the cover plates, which is not conducive to the installation and maintenance of the cover plates , It is easy to accumulate rain and snow, causing the seal at the joint to be damaged or even broken

[0010] 2. The vertical and horizontal reinforcement ribs intersect vertically, while the airflow inside the deodorization hood flows along the longitudinal direction of the hood. The horizontal reinforcement ribs have a great hindering effect on the airflow, which will cause airflow disorder and increase resistance
