Structural characteristics and cooling principle

The emulsion explosive cooler is the core equipment in the cooling process of emulsion explosives. Its structure is shown in the figure below and is suitable for cooling emulsion explosives. The internal structure of the JHF series enhanced heat transfer reactor developed by our company is similar to that of a static mixer, which enables different liquids entering the emulsion explosive cooler to mix well with each other. However, unlike the internal units of conventional static mixers, its internal components are not made of plates but of thinner pipes, and the inside of the thin pipes can be filled with heating or cooling media. Therefore, the internal units not only achieve sufficient mixing, but also provide a large heat transfer specific surface area.

2、JHF-IItypeEnhanced heat transfer hybrid reactor

For strongly exothermic liquids/The liquid reaction process can be carried out usingJHF-ⅡType enhanced heat transfer hybrid reactor.JHF-ⅡHorizontal installation of type enhanced heat transfer mixed reactor withSVType static mixer as an accessory to ensure immiscible liquids/The liquid phase is uniformly mixed and requires a longer residence time for the liquid/In the liquid reaction process, the length of the static mixer is also relatively long, and at this time, it can be used between each static mixer180°The bends are connected to each other to form a unit reactor.Mainly used for:

(1) Cooling of Polyester Melt

(2) Acrylonitrile ammonification reaction

(3) Reaction of chloroacetic acid and ammonia gas

3、JHF-IIItypeEnhanced heat transfer hybrid reactor

For strongly exothermic gases/The liquid reaction process can be carried out usingJHF-Type III enhanced heat transfer mixed reactor.JHF-The Type III enhanced heat transfer mixed reactor is installed vertically. Generally, the gas-liquid two-phase flow in the reactor moves upward, and the bottom of the reactor is equipped with a specially designed gas distributor. In special circumstances, the gas-liquid two-phase flow in the reactor can also move downward in parallel, and the top of the reactor is equipped with a specially designed liquid distributor. Mainly used for:

(1)Cooling of Polyester Melt

(2)Acrylonitrile ammonification reaction

(3)Reaction of chloroacetic acid and ammonia gas

4、JHF-IVtypeEnhanced heat transfer hybrid reactor

JHF-ⅣThe type enhanced heat transfer hybrid reactor can effectively mix different fluids entering it and enhance the heat transfer process of high viscosity media, making it particularly suitable for use as a polymerization reactor.JHF-ⅣThe uniform temperature distribution at the same cross-section inside the polymer is not only beneficial for improving the product quality of the polymer, but also for increasing the conversion rate of the polymerization reaction. From monomer to complete polymerization, the viscosity of the reactants undergoes a process from small to large, and the higher the degree of polymerization, the greater the viscosity. Can be withSVIt can be used in conjunction with a static mixer or a stirred polymerization kettle.
