Compression Condensation Technology Product Introduction
The device is mainly composed of a compression unit, a condensing unit, a refrigeration unit that independently provides cooling for the condensing system, and an electronic control unit, and each main equipment unit is arranged in a prefabricated box for easy installation.
1) Compression system:It is mainly composed of 1.1-compressor unit, 1.2-gas-liquid separation tank, 1.3-compressed liquid heat exchanger;
2) Condensation system:It is mainly composed of 2.1-dichloromethane primary cooler, 2.2-dichloromethane secondary cooler, 2.3-dichloromethane tail gas heat exchanger, 2.4-dichloromethane storage tank, 2.5-dichloromethane drying separator;
3) Refrigeration unit:It is mainly composed of 3.1-refrigeration unit, 3.2-cold water tank, 3.3-water pump;
The compression condensing device compresses and condenses the waste gas containing volatile organic compounds (VOCs) emitted by various factories or equipment to 0.8MpaG (adjustable pressure). The compressed raw gas produced by the compressor enters the gas-liquid separator along with a large amount of dichloromethane coolant (dichloromethane is taken as an example here); under the action of the gas-liquid separator, the separated liquid dichloromethane is stored at the bottom. When the liquid level reaches a high level, the control valve is opened to discharge the liquid to the dichloromethane storage tank in the tank area under high pressure for recycling and reuse; the gaseous tail gas enters the rear-end condensation unit for further condensation.
Product Advantages
Simple process and good performance——Compression condensation recovery system has a simple process flow, is easy to operate, and can meet the working conditions of high concentration and large air volume.
Mature technology and low cost——The compression condensation recovery system has mature technology, relatively low cost, small footprint, easy maintenance, low operating cost, and only consumes electricity and cooling water. The recovery benefits far outweigh the energy consumption expenditure.
High degree of automation and easy operation——Reasonable PLC automatic control system design can achieve unattended operation. The operator only needs to supply power to start the program, and the system will enter the automatic cycle working program. It realizes the intelligent VOC treatment process, further improves the treatment efficiency of the device, and further reduces investment and operating costs.
Safe, reliable and easy to operate——Screw compressors, high-efficiency condensers and other equipment are strictly strength-calculated according to the use conditions such as pressure, temperature, concentration, etc., and corrosion-resistant materials are selected. Perfect operation process design to achieve standard emission of organic gases.
