In the petrochemical, coal chemical, pharmaceutical, biochemical fermentation, new material preparation, waste water treatment and other industrial fields, "micro-interface mass transfer enhanced reactor" finally has an "upgraded version." On April 9th, the “Micro Interface Mass Transfer Intensification Reaction—Fine Separation Integrated System R&D†project completed by the Nanjing University and other organizations passed the China National Petroleum and Chemical Industry Federation’s scientific and technological appraisal. The technical level of the device has made it impossible for the counterparts of developed countries to walk. The production lines were closed one after another.
According to Zhang Zhibing, general manager of the project's technology, a major innovation in the project is the development of a micro-interface mass transfer enhanced reactor (hereinafter referred to as MTIR) and the establishment of a mathematical model for the regulation of structure and effect, enabling ultra-fine gas-liquid particles to be realized. Breakage and regulation of efficiency and energy consumption. Most of the gas-liquid particles in the reaction system can be in the range of 25 μm to 1 mm in diameter, whereas the bubble diameter in conventional reactors is usually 5-20 mm.
"In order to carry out this appraisal, we conducted a 72-hour continuous assessment of this project." Chief of the China Petroleum and Chemical Industry Federation Jiang Yiru told reporters. Compared with the traditional tower bubble reactor production system, the unit reactor interface area of ​​MTIR increased by 500%, and the production intensity increased by 177% from 18.5 kg/m3.h to 51.2 kg/m3.h. The product's output has increased dramatically over time.
Zhang Zhibing said that due to the implementation of this technology in a company in Jiangsu, the similar product lines of Japan’s Mitsubishi Gas Chemicals Co., Ltd., which has been dominant in the international market, and the United Kingdom branch of British Imperial Chemical Industry Co., Ltd. have successively declared closed.
Air To Air Heat Exchanger
A series of thin metal plates parallel to each other and pressed with a distance column are stacked to form a plate air-Air Heat Exchanger. The main components are heat transfer plates, outer frame sealing plates, compression device and so on.
The plate adopts full welding seal, flue gas and air cross flow between the plate for heat exchange. It`s suitable for air preheating and waste heat recovery in steel, chemical, electric power, battery and other industries, especially suitable for ultra-high temperature air to air heat exchange field.
Tranp`s Plate Air-Air Heat Exchanger is especially suitable for heat exchange between gas medium with high corrosion, high dust and high humidity.
The surface of the heat exchange plate is smooth with strong self-cleaning ability, so it is easy to clean. And multiple process is available, which is customized for different working conditions. Besides, the processing capacity can be as low as ten, but also as high as thousand CBM, therefore it`s widely used in waste heat recovery. What is more, the plate adopts advanced welding equipment and technology, combined use of resistance welding and manual welding between plates ensures that the weld joint is not easy to burst.
