Chemical plant gas collection hood specification fiberglass sewage tank arch cover integrated sewage treatment equipment

1、 Introduction to sewage tank cover:
We have accumulated rich experience in the design, installation, and construction of sewage tank covers and sewage tank gas collection covers. For many years, the company has processed and produced various specifications of fiberglass gas collectors according to customer requirements. The products produced have good strength, reasonable price, and excellent anti-corrosion performance. Effectively collect and treat exhaust gases. It is a choice in exhaust gas treatment.
Our main business includes sewage tank capping (including arch capping, sewage tank fiberglass cover plate, sewage tank gas collection hood, biological deodorization cover plate, odor gas collection), etc. We have been committed to the application of environmental protection technology and have reached cooperation or cooperation intentions with foreign enterprises. We have also invited experts in various environmental protection fields to serve as technical consultants for our company for a long time.
2、 Background of sewage tank cover and fiberglass sewage cover:Specification of gas collection hood for chemical plant - FRP sewage tank arch cover plateWith the rapid development of our country's economy, especially in industries such as petrochemicals, fertilizers, wastewater treatment, animal husbandry, and municipal sewage treatment, the pollution of odorous gases has rapidly and seriously affected the surrounding areas and people's lives, endangering human health. To solve this situation, Yuanrun Glass Steel Plant has relied on years of environmental protection equipment production design, combined with its own actual situation, to produce fiberglass gas collection hoods. The hood covers the pool body and seals the exhaust gas overflow. The deodorization device is used in conjunction with pipelines, fans, purification towers, and other accessories to achieve the purpose of air protection.Specification of gas collection hood for chemical plant - FRP sewage tank arch cover plate
3、 Working principle of sewage tank cover and fiberglass sewage cover
Add a fiberglass gas collection hood above the sewage tank to isolate the waste gas generated in the tank from the air. Add an air outlet on the surface of the gas collection hood and install a ventilation duct. The waste gas enters the waste gas purification tower through the ventilation duct. To increase the collection of waste gas, install a fiberglass fan in the purification tower. The waste gas is purified by the fan and sprayed in two stages inside the tower. If the waste gas is acidic, it is absorbed by alkali solution circulation. If the waste gas is alkaline, it is absorbed by acid solution circulation spray. The waste gas treatment efficiency reaches over 90%, which is related to emissions.

4、 Technical points of sewage tank cover and fiberglass sewage cover
Made entirely of fiberglass material, it has advantages such as corrosion resistance, flame retardancy, durability, anti slip, lightweight, easy installation, no need for insulation, etc.
1. Strong corrosion resistance: This product is made of acid and alkali resistant and corrosion-resistant resin as the base material, using excellent curing formula and curing process. According to the condition and shape of each sewage tank, a fixed mold is determined as the external mold for curing and forming.
2. Low cost, long service life: Compared with other sewage tank deodorization solutions, it has low cost, simple installation and construction, and long service life.
3. Lightweight and easy to install: The specific gravity of the fiberglass gas collection hood is only 1/31/4 of that of steel products, with a high degree of curing, heavy load capacity, and strength, suitable for large-span pool bodies. At the same time, the cover plate can be divided into several small pieces for easy transportation and installation.
4. Beautiful and anti-aging: The product is made of anti-aging, weather resistant and gel coat resin, with smooth, beautiful and bright surface, and has been used for more than 20 years.
5. Low operating costs and convenient maintenance: Due to its corrosion resistance, aging resistance, and no need for regular maintenance like metal products, this product incurs significant costs. Reserve observation windows on the gas collection hood and maintenance doors at the ends for easy maintenance by workers without affecting the normal operation of the equipment.
6. Strong designability: The product size can be flexibly designed according to the on-site pool situation, and the shape can be made into curved cover, circular cover, flat cover, etc.
5、 Specifications for sewage tank cover and fiberglass sewage cover
The specific size specifications of the product can be provided by the customer, or our company can provide a design proposal after the customer has requested usage.
6、 Application scope of sewage tank cover and fiberglass sewage cover
Suitable for deodorization of wastewater treatment plants' sewage tanks in industries such as petroleum, chemical, urban sewage treatment, food, metallurgy, compound fertilizer, textile printing and dyeing.

Anti corrosion measures for deodorizing fiberglass sewage tank cover plates: 1. Requirements for deodorizing substrate of fiberglass sewage tank cover plates: The tank walls and bottom should be pre treated with PVC layer waterproof treatment, and the cement surface layer should be smooth without hollowing, powdering, cracks, and anti alkali; 2. Deodorizing substrate treatment: Is there any hollowing on the pool wall and bottom? If there is hollowing, it is necessary to knock it open and then use epoxy sand? Different processes for covering sewage tanks: 1. Some of the odors from water cleaning and chemical deodorization can be dissolved in water. Water cleaning utilizes this property, allowing gases such as ammonia in the odor to dissolve better with water and effectively clean the odor. Some of the odors can undergo neutralization reactions with the chemical components in the medicine. The sewage tank cover plate can be divided into fiberglass cover plate and reverse hanging membrane cover plate according to the different covering materials. These two types are widely used in the market for sewage tank cover plate. Reverse hanging membrane cover plate is more commonly used than fiberglass cover plate, and its corrosion resistance and sealing performance are better than fiberglass cover plate. It is widely used in sewage tank cover plate nowadays. What are the correct covers for sewage tanks. With the development of modern society, the distance between sewage tank covers and ordinary people has increased. For example, the volatilization of waste gas from a company's sewage tank into the air can seriously affect the air and may even have a significant impact on people's health. So, adding a cover plate to the sewage tank is crucial.
