Product Description

Tower Type Steel Chimney

The chimney of tower rack structure is made of steel. The finished product has the characteristics of low cost, short production cycle, long mission, convenient processing, simple installation, light weight, high strength and stiffness. It is made of glass steel with smooth internal and external surface, anti-aging performance and excellent internal corrosion performance at high temperature. And can be convenient to increase the spray, filter screen to absorb harmful components in the flue gas. We have developed a mature and reliable production and installation process to ensure the accuracy of chimney installation. It is widely used in electric power, chemical fertilizer, chemical industry, smelting, petroleum and other industries, as corrosive or high temperature flue gas treatment equipment.

Advantages of Tower Type Steel Chimney

Low cost, short production cycle, long service life, easy installation, simple installation procedure, light weight, beautiful and simple appearance, high strength and rigidity, strong anti-corrosion performance.

Height of Tower Type Steel Chimney

The height of the Tower Type Steel Chimney structure is generally above 20 meters, which is generally an integer, such as 20 meters, 30 meters, 50 meters, 80 meters, 100 meters and so on. It is generally calculated according to the needs of customers!

Tower chimneys manufacturers believe that in industrial production, all the chimneys or exhaust chimneys that discharge various kinds of treated exhaust gas at high altitude have anti-corrosion problems. The main factors to be considered in the anti-corrosion design of exhaust chimney are: chemical composition, temperature, humidity, gas pressure and flow rate, whether coagulative acid will be formed on the surface of cylinder wall. The dew point of the wall can be calculated according to the composition, temperature and humidity of the discharging medium. There are several scenarios:

1.Tower chimney manufacturers think that under normal circumstances, the temperature is often more than 150 high temperature chimney is not easy to condenses on the chimney wall, rarely form coagulative acid, so the corrosion is relatively light, such as the power plant does not desulphurize the chimney.
2.Tower chimney manufacturers think that the temperature is below 150 and contains a lot of corrosive gas and soluble salt chimney corrosion is serious. For example, nitric acid production exhaust vent, gas temperature is less than 90 and nitrogen oxide content is relatively high; The exhaust gas of sulfuric acid production is empty, the gas temperature is lower than 60 and contains a lot of sulfur dioxide. The chimney of non-ferrous tin smelter has a flue gas temperature of 60~70, containing hydrogen fluoride and sulfur oxide, and the flue gas temperature of alkali furnace of paper factory is below 110, containing various sodium salts; The viscose workshop of chemical fiber plant emits hydrogen sulfide, carbon dioxide and other gases at room temperature. In short, under the action of corrosive gases and dust below the dew point temperature of the flue gas, the chimney is generally seriously corroded.
Tower chimneys manufacturers believe that the common corrosive gases in desulphurization chimneys of power plants are unpurified sulfur dioxide and residual sulfur trioxide. Sulfur dioxide in contact with water becomes sulfite, sulfur trioxide in contact with water becomes sulfuric acid. By ion exchange with hydrate in sulphated concrete, soluble calcium salt, aluminum salt, iron salt and silica gel are generated. The alumina in clay bricks can also form soluble salts with sulfuric acid. The salt in flue gas is also a significant medium. Many soluble salts can penetrate into brick and concrete, absorb water, recrystallize and expand, damaging the structure of the material. The solid dust in the flue gas causes certain wear to the inner wall of the chimney. This factor should be taken into proper consideration when selecting the material and lining of the chimney.
Tower chimney manufacturers believe that the chimney of dry smoke discharge serious corrosion in the upper part of the chimney, affected by outdoor air, easy to form coagulative acid. Lined chimney, corrosive medium easy to invade the part, one is the intersection of the lining section, such as the support of the outer cylinder; Secondly, the flue gas medium through the gap of brick masonry: into the outer cylinder and lining between, and then corrosion of the outer wall.

Tower chimneys manufacturers consider that wet chimneys and wet (semi-dry) chimneys with corrosive exhaust should be made of or lined with corrosion-resistant materials. According to different working conditions, different anticorrosive materials and different structural forms can be used:
1. The flue and chimney with serious corrosion can be made of plastic, acid-resistant stone, acid-resistant brick, glass steel, stainless steel, alloy steel, titanium plate and so on. According to different corrosive media and working conditions.
2. For mildly corroded chimneys, acid-resistant concrete and coated lining can be used.
3. For the chimney with serious corrosion, it is generally not suitable to use the brick outer cylinder. In chemical industry, metallurgy, papermaking, boiler chimney corrosion after forced demolition examples, corrosion basically occurred when the outer barrel is brick masonry. Brick chimneys (including lined ones) are difficult to reinforce after corrosion and prone to instability due to local corrosion.

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.
