Weifang Yide Heat Exchange Equipment Co., Ltd.

Yide Heat Exchange Equipment Co., Ltd. is a national science and technology small and medium-sized enterprise/high-tech enterprise. It is a strategic cooperative unit with Shandong Provincial Marine Chemical Research Institute. Both sides jointly build a joint laboratory for bromine production equipment and energy saving technology; The company focuses on manufacturing and technical innovation of series products of strong corrosion resistant heat exchange (condensation) equipment, including silicon carbide heat exchanger/glass heat exchanger/carbonized composite tube heat exchanger/strong acid heater and supporting corrosion resistant pipe fittings; It is applied to

1. Tubular heat exchange, tubular reaction, falling film evaporation, reboiling, etc. Required for strong corrosion resistant products;

2. High (low) temperature flue gas waste heat recovery and utilization field

3. System engineering of waste acid purification or concentration process. The company is located inWeifang Binhai Economic and Technological Development Zone, the deep processing base of bromine and bromide series products in China. Silicon carbide heat exchanger is a new type of heat exchanger that utilizes silicon carbide ceramic material as the heat transfer medium. Because silicon carbide ceramics have corrosion resistance, high temperature resistance, high thermal conductivity, high hardness, wear-resistant and other excellent characteristics, silicon carbide ceramic heat exchanger is suitable for high-temperature, corrosion-resistant environment.

Developed into this device heat exchanger element material is a new type of silicon carbide engineering ceramics, it has high temperature and thermal shock resistance performance, from 1000 º C air-cooled to room temperature, repeated more than 50 times without cracking; Thermal conductivity and stainless steel equivalents; In the oxidizing and acidic media with good corrosion resistance. In the structure of the successful solution to the thermal compensation and a better solution to the gas sealing problem. The device has high heat transfer efficiency and remarkable energy-saving effect, which is used to preheat the combustion air or heat the process gas of certain processes, and can save primary energy, the fuel saving rate can reach more than 30 %, and can strengthen the process and significantly improve the production capacity.

Tubular silicon carbide inserted high-temperature heat exchanger is a new type of heat exchanger developed to replace the metal heat exchanger, to solve the problem of its long-term operation in high-temperature flue gas is unreasonable and need to be used against the defects of the cold air, reducing the effectiveness of the use of the new heat exchanger device. The heat exchanger made of this material is a new generation of high temperature flue gas waste heat recovery products in the international arena. Tubular silicon carbide insert high-temperature heat exchanger has a compact structure, large heat transfer area per unit volume, the use of internal spring compression can absorb thermal expansion, in the flue gas temperature of 1300 º C, the air preheating temperature of up to 600 º C or more, the heat exchanger′s interface part of the corresponding technology to reduce vibration to strengthen the seal to reduce air leakage, air leakage rate of less than the professional requirements of less than 5 %.

Silicon carbide heat exchanger is made of a number of air channel cross-section for the square, flue gas channel cross-section for the rectangular silicon carbide tubes were cross-stick together, the air channel and flue gas channel compartment for the double-layer, the structure is solid, with high mechanical strength, it solves the corrugated ceramic heat exchanger spacer cracking easy to leak the phenomenon of wind.
