Desulfurization and Degassing Self-supporting Steel Chimney

The Desulfurization and degassing self-supporting steel chimney belongs to the technical field of steel chimney, including an inner cylinder and an outer cylinder, the inner cylinder is arranged in the through hole of the outer cylinder, the inner cylinder has an elastic cylinder part, the elastic cylinder part has a gap between the elastic cylinder part and the outer cylinder, the elastic cylinder part can be deformed along the axial direction of the inner cylinder. The utility model has the advantages of simple structure, absorbing the impact force of the gas in the inner cylinder through the deformation of the elastic cylinder part, thereby reducing the impact of the connection between the inner cylinder and the outer cylinder and the inner cylinder, and increasing the stability of the connection between the outer cylinder and the inner cylinder.

The Desulfurization and degassing self-supporting steel chimney comprises an inner cylinder and an outer cylinder. The inner cylinder is arranged in the through hole of the outer cylinder. The inner cylinder has an elastic part, and the elastic part is provided with a gap between the elastic part and the outer cylinder, and the elastic part can be deformed along the axial direction of the inner cylinder.
The elastic cylinder part is corrugated steel pipe.
The inner cylinder comprises a plurality of inner cylinders, which are successively connected and connected with each other from top to bottom.
Each section of the inner cylinder comprises an upper connecting pipe, a lower connecting pipe and a bellows, the upper and lower ends of the bellows are respectively connected with the upper connecting pipe and the lower connecting pipe, the lower connecting pipe of the inner cylinder located above is connected with the upper connecting pipe of the inner cylinder located below it.
The inner wall of the bellows is provided with a retaining ring.
The baffle ring is provided with a number of through holes.

The outer wall of the connecting pipe is provided with a connecting piece, and the inner wall of the outer cylinder is provided with a supporting piece, and the connecting piece is connected with the supporting piece.
The bottom surface of the connecting piece is in contact with the top surface of the supporting piece, and the supporting piece is fixed between the connecting piece through the vertical fixing rod.
The connector on the inner cylinder is a ring, and the outer diameter of the annular connector on the multi-section inner cylinder decreases from top to bottom.
As a further optimization scheme of the utility model, the connector on the inner cylinder is block, and the block connector on the multi-section inner cylinder is uniformly distributed on the circle formed on the outer wall of the inner cylinder in a circumferential direction.

In this paper, Desulfurization and degassing self-supporting steel chimney is proposed. Through the elastic deformation of the elastic part of the inner cylinder along the axial direction of the inner cylinder, the impact of the connection between the inner cylinder and the outer cylinder is reduced, and the stability of the connection between the inner cylinder and the outer cylinder is increased. There is a gap between the elastic cylinder part and the outer cylinder, on the one hand to facilitate the deformation of the elastic cylinder part, on the other hand to avoid the deformation of the elastic cylinder part and the outer cylinder contact and extrusion, so as to increase the service life of the outer cylinder.

Hebei Pude Yuelan Environmental Protection Equipment Co., Ltd. is an enterprise engaged in the development and production of industrial chimneys, the company focuses on the development and production of industrial chimneys.

Headquartered in Jingxian Development Zone, Hebei Province, the company has a registered capital of 60 million yuan, covers an area of 9.60000 square meters, of which the building area is 2600 square meters. The main products include self-supporting smoke, sleeve smoke, tower chimney, east smoke, cable smoke, stainless steel chimney, glass steel chimney, mobile compressed garbage bin, horizontal compressed garbage station, hook arm transfer truck, butt type garbage truck and dozens of products. The company has 128 employees, including 8 experts and engineers with master's degree or above, 60% of the employees with bachelor's degree or junior college degree, all kinds of technical personnel 26 people, 60 people special personnel, the company has a number of domestic offices and after-sales service institutions, can provide technical support and product services at any time.
 
The company's production equipment advanced, strong technical force. Has more than 50 sets of domestic advanced production equipment, including foreign, domestic CNC production lines 6; Hot-dip galvanizing adopts the galvanizing technology and process of Gimeco Company in Italy, and its technical level and production capacity are at the advanced level in China.

After years of development in chimney and municipal waste treatment equipment industry, the company has become a well-known brand in the industry. Through the cooperation with domestic and international design institutes, colleges and enterprises to continuously improve the enterprise's scientific research and development ability. And has cooperated with many universities and reached strategic cooperation with petrochina, Sinopec, Huadian, Huaneng and other enterprises.

In recent years, in order to solve the problem of large-caliber smoke, the company has established a technical cooperation relationship with Beijing Jiaotong University, and invested a lot of manpower and material resources to develop the "precast factory, on-site construction" steel corrugated chimney and urban waste environmental treatment products. At present, the pipe diameter range of the company's products is 0.5m-20m, and the annual production capacity is 660,000 meters.

The company always adhere to the "quality, user" of the enterprise purpose, do not ask for the number of projects, just do the project to make good quality principle, products have been promoted in the project use. Today, the company's products still maintain zero defects, zero complaints, zero accidents, by the owners, construction units of the consistent praise, and establish a long-term cooperative relationship.
