I. Overview:
1. In the modernization process of our country, the environmental pollution accompanying the whole process of industrial modernization has become the biggest safety hazard, and the state's management of the "three wastes" of industrial enterprises is becoming increasingly strict. VOCs are the key waste gas in the process of industrialization, and complete treatment is the top priority. At present, the harm of high concentrations of VOC is mainly reflected in two aspects. On the one hand, some substances in VOC will cause direct harm to the human body. These hazards to the body are mainly reflected in the hazards of chemical substances, absorbed by the human skin or breathing, causing nervous system disorders, and the hazards of other compounds, etc. If it volatilizes into the atmospheric environment, it will not only cause serious pollution to the atmospheric environment, but also cause immeasurable damage to industry and agriculture, water resources, animals and plants, etc.
2. The design and development of VOC ( organic gas ) purification treatment process mainly focus on two aspects : separation, conversion, purification and recovery. Currently, there are several common methods for treatment.
2. VOCs treatment in the process of industrial production --- common treatment is technical classification
The recovery of VOC can be carried out by membrane separation, absorption, adsorption, condensation and other methods
3. Treatment of VOCs in the process of industrial production --- technical description
1. Molecular sieve (or semi-permeable membrane) recovery and separation technology has become the latest processing technology with the development of membrane material separation technology. Membrane separation technology still needs to be carried out under certain high-pressure operating conditions, and low-pressure nanofiltration VOCs gas separation membrane is selectively separated . Although our company is at the forefront of the industry in terms of material adaptability, it is still in the expectation stage of continuous development, which is also the direction of our Jinke Group's future research and development and development.
2. The absorption method mainly uses other liquid organic solvents to absorb and purify the gases, and then separates and recovers them through rectification.
3. There are strict requirements on the selection of absorbent and the post-treatment of the absorbent, and are generally only suitable for some specific occasions.
4. In terms of carbon adsorption, our company has professional zeolite runner technology and activated carbon box unit treatment technology.
5. Plasma / photocatalysis is generally used in conjunction with absorption and adsorption technology.
6. Condensation recovery technology is the best choice for environmental protection and resource saving.
4. Treatment of VOCs in the process of industrial production - Jinke Condensation Recovery
Condensation law is often the last resort for recovery of gaseous organics
The condensation recovery system designed by our company is mainly suitable for higher concentration occasions, and is usually used as a follow-up supporting unit for some other gas concentration processes. The products developed and designed by our company are standard configurations for VOCs concentration post-treatment, and VOCs treatment is also carried out at the same time A model for industry-only use.
5. Jinke Condensation Recovery System
Brief introduction: The mature special-purpose condensation integrated treatment device developed and designed by our company cooperates with Jinke intelligent digital management system.
The design is perfect, the auxiliary equipment is complete, and the automatic purification efficiency, comprehensive recovery efficiency and energy consumption indicators are in the leading position in the same industry.
It is used in the purification and recovery of organic waste gas discharged from various industries such as petroleum, chemical industry, medicine, and various new energy and environmental protection industrial automation, intelligent painting workshops, etc.
6. Jinke Condensation Recovery System -- Process Flow
1. The exhaust gas enters the treatment system after being collected by the pipeline;
2. Enter the zeolite runner to concentrate after primary and medium effect filtration;
3. The waste gas after concentrated treatment enters the negative pressure fan and directly discharges up to the standard
4. During the concentration process, part of the wind cools the runner, and after cooling, the wind enters the high-temperature heating chamber to heat up;
5. The hot air returns to the desorption chamber of the zeolite runner for desorption;
6. Concentrated isopropanol enters a surface cold separation;
7. Separating gaseous isopropanol into liquid and flowing into the tank for collection;
8. The concentrated wind enters the secondary surface cooling separation;
9. After the secondary separation, the gaseous isopropanol is converted into a liquid and flows into the tank for collection;
10. Liquid isopropanol contains other components and water into the recycling bin;
11. The exhaust gas treatment rate after secondary condensation and separation far exceeds the national emission standard and then discharges up to the standard.
12. Merged into Jinker2.5 intelligent automatic control system and safety warning system.

8. Jinke Condensation Recovery System -- Advantages
The performance of the condensation recovery system is high efficiency / energy saving / stable / safety / environmental protection--
Purification efficiency of Jinke condensation recovery system: it can fully recover the organic components in the waste gas, and the system recovery efficiency is high. The general purification rate is over 95% , and under special requirements, such as Jinke isopropanol condensation recovery rate can reach over 99% .
The circulation heat exchange system has excellent energy-saving effect, automatic operation, intelligent management is more stable, unmanned working environment, multi-layer protection settings cooperate with Jinke early warning system multi-level security to ensure safety, and the environmental protection mode of physical recycling will not produce Hidden dangers of industrialized secondary pollution.
