Recycling technology


1. Technical ideas

Aiming at the system's release of waste heat resources, based on the current process route, combined with the system process, the system's waste heat resource generation method, the amount of waste heat resources, and the parameter change range are investigated, and the returned steam is preferentially returned to the system for reuse according to the released steam. The principle of reasonable use of the minimum released steam can realize the cascade utilization of waste heat resources, improve the utilization of waste heat resources and the economic benefits of the system. Through the recovery of waste heat resources, combined with the actual cooling and heating loads and power equipment configuration in the system process network, it can be used to drive loads (such as pumps, fans), generate electricity, cool (for air conditioning or equipment cooling), and heat (such as heating, desalinated water) Deaeration, preheating medium, etc.).

2.Technical advantages

模拟软件分析,从系统能量平衡入手,做好热能梯级利用,减少余热资源放散量,提高系统经济性; A. Use WHPN simulation software analysis to start from the energy balance of the system, make good use of the thermal energy cascade, reduce the amount of waste heat resources released, and improve the system economy;

B. According to the energy requirements of the system, a complete set of product series with superior performance and flexibility can be provided for a variety of uses, including power generation, driving, cooling, heating, etc .;

C. It has a wide range of applications and can be applied to any high temperature liquid, saturated water vapor, low pressure water vapor, high temperature flue gas, superheated steam, etc.


3. Features of some supporting products

1 ) Screw expansion power unit

A. The heat source has a wide range of applications. The heat source is not high. Superheated steam, saturated steam, soda water, hot water, high temperature flue gas, and other hot fluids can be used. It is pure waste heat utilization.

范围)波动的情况下,仍可稳定、高效地运行。 B. Excellent ability to change working conditions. Under the circumstances that the heat source load and parameters fluctuate in a large range (ranging from 20% to 120% ), it can still run stably and efficiently.

C. Low maintenance cost It belongs to the power machine without major repair for ten years. The minor maintenance and operation are simple and convenient, and will not affect the original system.

以下放散蒸汽饱和蒸汽通过优化设计,净发电量可达 105kW D. High isentropic efficiency: ≥85% isentropic efficiency is used to measure the thermal perfection of the main engine of the expander. The higher the isentropic efficiency, the higher the energy conversion efficiency. The saturated steam released under 1t / h and 5kgf is optimized and designed. , The net power generation can reach 105kW .

E. The implementation of the project is convenient for the integrated design of the unit, and it can be installed separately according to site requirements. Construction and movement are very simple.

F. Unit operation and management is convenient for unit start-up and simple operation with load, which can realize unattended operation.

2 ) Turbine Power Unit

A. Supply and supply from well-known domestic manufacturers, excellent performance and high internal efficiency;

g )饱和蒸汽即可满足要求; B. Wide application range, the minimum steam supply parameter 0.25MPa ( g ) saturated steam can meet the requirements;

C. Customized according to the released steam parameters after system optimization, which can be applied to different steam parameters and operates in the high efficiency zone;

D, advanced operation control system, equipment safety and stability;


4.Application

It is widely used in iron and steel metallurgy, petrochemical industry, biochemical pharmacy, thermoelectricity, and other industrial and mining enterprises to recycle superheated steam, saturated steam, steam-water mixture, hot water, high-temperature flue gas, and other hot fluids.
