Description

Technical Field

[0001] The invention relates to the technical field of odor collection, and in particular to a full-glass fiber reinforced plastic deodorizing cover plate with an internally integrated air duct. Background Art

[0002] In the past, the source control of malodorous gases mainly focused on collecting the pollution sources at the source, and the collection methods were diverse. In the field of municipal sewage treatment, it was usually to cover (cover) the structures (buildings) for sewage or sludge treatment. Traditional odor collection devices mostly use inverted fiber membranes, FRP single arch plates with steel pipe frames, and Capron plates lined with stainless steel frames, etc., which have many disadvantages, such as: the inverted fiber membrane needs to be supported by a steel frame, which is heavy, and some existing sewage pools cannot bear its weight, the clearance is high, the deodorization air volume is large, people work inside, the environment is harsh, and it is easy to form a collection dead corner; the FRP cover plate wrapped with steel pipes inside is prone to cracking due to the temperature difference between day and night, and has a short life; the lined stainless steel frame is exposed to the environment with high odor concentration in the deodorization hood for a long time, and its stainless steel components will corrode.

[0003] Prior art 1: An ultra-large span all-glass fiberglass deodorizing cover plate with application number 201711228680.2, which is made of high-strength glass fiber reinforced plastic without metal frame support, characterized in that the cross section of the cover plate is a large span arch, and the longitudinal section is a continuous small span arch. The cover plate is connected by a number of cover plate units, each of which includes two semi-arched side wings on both sides, and the recessed portion between the two semi-arched side wings forms a pedestrian passage. The outer ends of the two semi-arched side wings are respectively provided with connecting flanges, and the connecting flanges are located at the top of the semi-arched side wings. Two adjacent cover plate units are connected by connecting flanges, and the connected flanges form a longitudinal reinforcing rib located outside the cover plate. Odor collection ports 6 are provided at both ends of the cross-sectional direction of each small span arched unit of the cover plate, and are connected to an external pipe for odor collection.

[0004] The prior art has the following defects:

[0005] 1. The air suction ports of the deodorizing air duct are arranged at both ends of the deodorizing hood. The airflow inside the hood flows along the longitudinal section of the hood. The distances from various parts of the hood to the air suction ports are different, resulting in uneven air extraction and the existence of dead corners for collection.

[0006] 2. The cover plate is separated from the air duct, and a deodorizing air duct and bracket are still required on the upper part of the cover plate, which affects the appearance, increases the load on the cover plate, and prolongs the construction period.

[0007] 3. If you need to inspect the pool under the cover, you must first remove the deodorizing air duct and bracket above the cover before you can open the cover, which increases the difficulty of inspection and maintenance. Summary of the invention

[0008] In view of the shortcomings of the prior art, the present invention provides a full fiberglass deodorizing cover with an internal integrated air duct. For the first time, the deodorizing air duct is integrated inside the deodorizing cover to ensure that the odor in the space below the cover is evenly collected without dead corners; at the same time, it has the advantages of easy disassembly and assembly, safety, and beauty.

[0009] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0010] A full fiberglass deodorizing cover plate with an internally integrated air duct is made of high-strength fiberglass, the cross-section of the cover plate is a large-span arch, and the longitudinal section is a continuous small-span arch. The cover plate is formed by connecting a number of cover plate units, each cover plate unit includes two semi-arched side wings located on both sides, and a connecting flange is arranged at the outer end of the semi-arched side wings. The recessed portion between the two semi-arched side wings forms a pedestrian passage, and the corresponding semi-arched side wings of two adjacent cover plate units are connected by a connecting flange to form a small-span arch, and the connection is located at the top of each small-span arch. It is characterized in that a deodorizing air duct is arranged on the inner side of the bottom of the semi-arched side wing toward the small-span arch, the deodorizing air duct is arranged along the span direction of the cover plate cross-section, an air suction port is arranged on the side of the deodorizing air duct, and an air outlet is arranged above both ends of the deodorizing air duct.

[0011] Furthermore, the deodorizing air duct is formed by the lower part of the semi-arched side wing, the bottom plate and the side plate. The bottom plate is flush with the bottom of the semi-arched side wing, the bottom of the side plate is connected to the bottom plate, and the top is connected to the inner wall of the semi-arched side wing. The side plate is provided with an air suction port, and an air outlet is provided on the semi-arched side wing corresponding to the two end positions of the deodorizing air duct.

[0012] Preferably, the deodorizing air duct is made of fiberglass.

[0013] Preferably, the total span of the cover plate in the cross-sectional direction is 5-25 meters.

[0014] Preferably, circular air suction ports are arranged on both sides of the deodorizing air duct according to the principle of equal pressure difference.

[0015] Preferably, a deodorizing air duct is integrated in the cover plate to ensure that the odor in the space below the cover plate is collected evenly without dead corners.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The cover plate of the present invention breaks through the traditional arrangement of separating the collecting air duct from the cover plate, innovatively integrates the deodorizing air duct into the cover plate, and arranges circular air suction ports on both sides of the air duct according to the principle of equal pressure difference, ensuring uniform collection of odor in the space below the cover plate, greatly improving the collection efficiency, and completely eliminating collection dead corners.

[0018] 2. The cover plate of the present invention does not need to be provided with a deodorizing air duct and a bracket on its upper part, which is more beautiful than the traditional layout in which the cover plate and the branch pipe are separated. At the same time, the load of the cover plate is reduced, the construction period is shortened, and time is gained for the subsequent processes.

[0019] 3. For the sake of aesthetics and service life, the deodorizing air duct is usually made of stainless steel, so lightning protection measures must be considered during design. The cover plate of the present invention avoids this problem and saves engineering costs.

[0020] 4. The cover plate of the present invention can be directly opened for inspection and maintenance without removing the upper deodorizing air duct and bracket, which is convenient for inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
