The application advantages of Roots fans in the chemical industry mainly include the following aspects:

Performance aspect

1. Stable gas transmission:

- The air volume is relatively stable, and the flow rate changes little when the pressure is adjusted within the allowable range, which can provide continuous and stable gas power for the chemical process.

- Can ensure the stability and uniformity of gas feed in the chemical reaction system.

2. Can adapt to a certain pressure range: wide pressure selection range, with the characteristics of forced gas transmission, can meet the chemical production under different pressure conditions of gas transportation, reaction and other needs.

Equipment characteristics

1. Relatively simple structure:

- Fewer main parts, easy to daily maintenance and maintenance, reducing maintenance difficulty and maintenance costs.

- No complex wearing parts and internal structure, high reliability, reduce the interruption of chemical production due to equipment failure.

2. Durable:

- The rotor and other components of Roots fan have high strength and can adapt to relatively complex and harsh conditions in the chemical industry (such as a certain degree of dust, temperature changes, etc.).

- The equipment is stable and reliable, and can work continuously for a long time.

Safety and environmental protection

1. Good sealing:

- It can effectively prevent chemical gas leakage, avoid environmental pollution and safety hazards, especially for the transportation of toxic and harmful, flammable and explosive gases.

2. Low pollution:

- The medium is not easy to be polluted during its own operation, which can ensure the purity of the chemical gas transported and avoid adverse effects on the subsequent chemical process.

- The material of the parts in contact with the conveying gas is stable and not prone to chemical reactions.

Cost aspect

1. Procurement cost: Compared with some large centrifugal compressors and other equipment, its price is relatively low, and the early equipment investment cost is less.

2. Operating cost:

- Good energy saving effect (especially after conversion control transformation), and obvious advantages during partial load operation.

- Energy consumption is relatively reasonable, and the overall operating cost is more economical in long-term operation.

Other aspects

1. Wide applicability: It can be used for flue gas desulfurization in chemical plants, air transportation, sulfur dioxide transportation in sulfuric acid devices and nitric acid transportation in explosive gas devices.

2. Flexible operation: the start and stop are relatively stable, the operation is relatively simple, easy to achieve automatic control, and convenient to cooperate with other equipment and systems in chemical production.
