Product characteristics The JHF type static mixer is different from other types of static mixers in that it uses pipes to make internal units, which not only improves the heat transfer coefficient of various high viscosity media, but also Being able to maintain a high specific volume heat transfer area even after amplification ensures a high specific volume heat transfer rate. For high viscosity media with a viscosity higher than 3000 centipoise, JHF type heat transfer component The coefficient can reach 200-400W/m2 ℃, which is 4-5 times higher than that of ordinary tubular heat exchangers. Used for processes such as heating, cooling, and heat recovery in high viscosity media. Another JHF type A prominent advantage is that the temperature distribution is uniform at each section of the entire heat exchanger. It not only relies on the bidirectional flow of fluid from the shell wall to the center of the shell. Make the material temperature uniform, And it is uniformly heated (or cooled) from the inside. The advantage of JHF type is that it can basically eliminate the uneven polymerization caused by uneven temperature distribution when used as a polymerization reactor Uniformity is beneficial for improving the quality of polymers, reducing energy consumption, and increasing conversion rates. Common specifications JHF type static mixers with a heat transfer area of over 100m2 can be designed and manufactured according to process conditions and requirements.

Structure diagram Application examples The industrial applications of JHF static mixers can be divided into two categories: the first category is used for heat exchange processes in high viscosity media, and the second category is used as polymerization reactors. Heating and cooling of oils and fats in the food industry, heating and cooling of molten resins in the synthetic fiber and plastic industry, heating and cooling of polymer solutions, and heating of cosmetics in the daily chemical industry Heating and cooling of binders, heating and cooling of residual oil in the petroleum industry, heating and cooling of heavy oil, heating and cooling of crude oil, heating and cooling of molten asphalt, and frying The heating and cooling of emulsion explosives in the pharmaceutical industry belong to the first category of industrial applications. Used as a polymerization reactor for polystyrene, production equipment for styrene acrylonitrile copolymer, production equipment for acrylonitrile butadiene styrene nitrile copolymer, and as a polyamide |

The polymerization reactor of 6 and so on belong to the second category of industrial use. Ordering Instructions Static mixer is an advanced, efficient and energy-saving chemical unit equipment. Proper design and selection are key to achieving the desired excellent performance. Design of static mixer Planning is a highly specialized and targeted job. Generally, we provide free design services to our clients and hope that they can provide detailed information as much as possible. Difficult for users to mention We will also call on the database to assist in solving the design conditions provided. The relevant situations include the following aspects: 1. What process is it intended for? It would be best to inform about the relevant process situation. 2. What are the names and flow rates of the fluids involved? 3. Operating temperature and pressure? 4. Various physical and chemical data of the fluid involved at operating temperature and pressure, including density, viscosity, interfacial tension, thermal conductivity, etc. 5. Balance relationships, reaction kinetics data, etc. (or provide information on relevant small-scale experiments and current production conditions). Is the liquid being transported using a high-level tank or a pump? What is the height of the high-level tank from the static mixer? What is the pressure head (output pressure) of the pump? Is the gas being transported using a fan or a compressor? What is the pressure head (output pressure) of the fan or compressor? What is the allowable pressure drop for a static mixer? What are the process requirements that the static mixer is expected to meet? What is the required level of uniformity for mixing? What is the required extraction rate for extraction? Explanation: (1) Sometimes, items 6, 7, and 8 mentioned above need to be decided by the designer, meaning that users need to select pumps or fans based on the design results.(2) For the uniformity of the mixture, if the user cannot provide an indicator, it is generally determined by the coefficient of non-uniformity a × x1/2 |
