1. Application industry
Biopharmaceuticals, chemical synthetic pharmaceuticals
2. Industry characteristics
①The exhaust gas composition is complex and difficult to recover, and the concentration fluctuates greatly.
②Contains more difficult-to-handle gas and is corrosive, such as HCL, CH2CL2
③There are many sources of waste gas, and the collection pipeline is complicated
④The range of influence is wide. Most of the VOCs in the solvent waste gas have malodorous properties, low odor threshold, easy to diffuse, and a wide range of influence.
⑤ There are many accidents such as "running, dripping and leakage". Due to the many flammable and explosive substances in the production process, the reaction process is intense and the risk of production accidents is high.
3. Solution
①Before the treatment process is determined, the concentration and composition of the exhaust gas need to be accurately analyzed.
②The waste gas collection should be classified as far as possible to avoid the safety risks caused by the reaction of different types of waste gas after the convergence.
③The collection piping system needs to be accurately designed to ensure the effective collection effect. For example, piping system for airflow simulation.
④ The pipeline is treated with anti-static and anti-corrosion treatment. Regular inspection, cleaning, and sewage disposal.
⑤The classified waste gas needs to be pretreated, such as removing acid and alkali, removing halogen-containing components, etc.
⑥ At the front end of the RTO, set up safety measures such as LEL, flame arrestor, and emergency discharge.
⑦The parts of the RTO system in contact with the exhaust gas need to be treated with anti-corrosion.
⑧After RTO treatment, in order to prevent high temperature and residual corrosion, post-treatment measures are required. Such as cooling and lye washing to absorb.
⑨Using a low-nitrogen combustion system to minimize the emission of terminal nitrogen oxides and sulfides.
⑩For parts with corrosion risk, adopt quick assembly and disassembly design, which is convenient for maintenance.
4. Features of the new three-tower RTO
Incorporating advanced core valve technology in the United States, Ausiyi successfully developed a new three-tower RTO with a processing efficiency of 99.5%.
①Economy: Adopting advanced technology of the US headquarters, the US and China are listed simultaneously, both of which are foreign brands, and the investment and operating expenses are the same as the RTO of the two towers.
②Modular design: AuSSE uses many years of 3D design experience to modularize the equipment, which can be quickly installed and debugged, and uses the advantages of 3D visualization for humanized design.
③The processing efficiency adopts the unique valve structure that AuSSE has always been proud of. There are only two actuators. The structure is simple and easy to maintain. The valve switching speed is less than 1S. The valve is equipped with an active sealing device to automatically compensate for the loss of the sealing material due to fatigue. The leakage phenomenon, combined with the comprehensive effect of the third tower, ensures that the treatment efficiency can reach more than 99.5%, and the efficiency is balanced. Compared with the traditional three-tower RTO discharge speed, the fluctuation is very small!
④Finite element analysis: to verify the rationality, safety and economy of the design by means of finite element analysis. Equipment safety: AuSSE has unparalleled 40 years of RTO design and operation experience: It uses methods such as setting up emergency exhaust valves and supplementing fresh air to ensure the safe and efficient operation of the system. At the same time, the inside of the system is always connected to the atmosphere. Greatly improve system security.
⑤ Burner module: As the heart of RTO equipment, the burner is an important basis for reflecting the stability of RTO equipment to a certain extent. Using low-nitrogen, high-efficiency burners, on the one hand, better combustion parameters can be obtained by adjusting the combustion air and combustion head, and on the other hand, energy consumption and secondary pollution can be effectively reduced.
⑥Intelligent control: Based on big data, with VPN function, it can carry out remote warning, accumulate operating parameters, and operate intelligently.
