Project introduction:

The temperature of the hot and humid air and dry tail gas discharged during the production process by many enterprises such as petrochemical, coal chemical, fermentation, pharmaceutical, food, tobacco, feed, fertilizers, and synthetic materials is generally around 120 - 180 ° C, and some even reach as high as 20 ° C., the emission of a large amount of waste heat not only causes a great waste of energy, but also has a great impact on the quality of the atmospheric environment. Effectively solving this problem is of great significance to energy conservation and emission reduction, and it also has significant social, environmental and economic benefits.

Project Introduction:

This technology is suitable for the recovery and utilization of high-temperature hot and humid air and dry tail gas waste heat generated from industrial production processes such as petrochemicals, coal chemicals, fermentation, pharmaceuticals, food, tobacco, feed, fertilizers, synthetic materials, etc.

This process recovers the heat from industrial tail gas through a specially structured heat exchanger, and then uses the heat to preheat new air, so that the air has gained a certain amount of energy when entering the front-end preheater, thereby reducing the consumption of heating steam and achieving energy conservation. purpose.

This technical feature is to design heat exchangers with special structures for hot and humid air and dry tail gas under different working conditions to recover waste heat while recovering products and reduce dust content.

This technology has completed the design of a demonstration project for waste heat recovery of 150000m3/h soybean protein drying tail gas.

Technical services:

This technology can provide diagnosis of existing hot and humid air and dry tail gas treatment processes, equipment and operating conditions (Operating parameter testing, exhaust gas composition analysis, logistics and energy balance calculation, etc.), design of waste heat recovery plan for hot and humid air and dry tail gas (technical plan to be adopted, feasibility analysis of the technology to be adopted, total project investment budget estimate, project economic analysis); preparation of technical tender documents for project bidding, complete engineering design, key reactor design, installation and debugging or general project contract.

Project investment depends on the size of the factory and exhaust gas conditions.
