Electrically heated reaction kettle

Electrically heated reactor

Summary

Electrically heated reactors are primarily used in the petrochemical, chemical, rubber, pesticide, dye, and food industries. They are containers for completing processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, such as reactors, reaction vessels, decomposing kettles, and polymerization reactors. Materials commonly used include stainless steel and carbon steel. Electrically heated reactors are widely applied in the chemical, food, natural flavoring, food additive, and light industry sectors.

Equipment Structure

The electrically heated reaction kettle is composed of the kettle body, lid, stirrer, jacket, support, and transmission device, as well as the shaft seal device. The material and aperture can be customized according to the user's process requirements. Made of 1Cr18Ni19Ti stainless steel plate, the stirring types generally include anchor, paddle, worm gear, propulsion, or frame. It is a cost-effective and easy-to-operate unit that heats the oil inside the jacket directly with electric heating rods, achieving high heating temperatures. The reaction kettle consists of the lid, cylinder, jacket, stirrer, shaft seal transmission device, and support. It is suitable for various organic compounds for decomposition, synthesis, cracking, polymerization, and esterification reactions.

Heating methods include electric, oil, gas, water (or cooling), and open flame heating. Jacket types are: jacketed and semi-tubular, with all jacketed oil heating types equipped with flow directing devices. Agitation types generally consist of paddle, anchor, frame, helical, and scraper types. High-speed models feature diffuser impeller, turbine, high-shear, and propeller designs, allowing customers to select based on process requirements. Transmission types include standard motors, explosion-proof motors, electromagnetic speed control motors, and inverters. Heat exchangers come in trochoid pinwheel, worm gear, and planetary non-stop variable speed designs. Shaft seals are of the standard water-cooled packed, composite Teflon packed, and mechanical seal types. Discharge types include ball valves and lower expansion valves.

Equipment Features

Electrically heated reaction kettle features rapid heating, high-temperature resistance, corrosion resistance, hygiene, no environmental pollution, no need for kettle movement to heat, and ease of use.

Used in the oil, chemical, rubber, pesticide, dye, food industries, for processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, condensation, etc. It relies on thorough mixing of the reacting substances and requires a stirring device for effective heat transfer, cooling, liquid extraction, and gas absorption processes. We can design and process external coil reaction vessels for our customers.

Equipment Categories

Jacketed methods include jacketed type and external half-tube type, with all jacketed oil heating types equipped with flow guides. Mixing methods commonly include paddle, anchor, frame, screw blade, and scraper types. High-speed types include diffuser impeller, turbine, high-shear, and propeller styles, allowing customers to select based on their process requirements. Transmission methods include standard motors, explosion-proof motors, electromagnetic speed control motors, and inverters. Gearboxes come in cycloidal pinion, worm gear, and planetary variable-speed designs. The shaft seal is typically a water-cooled packed gland, a combined packed gland, or a mechanical seal.

The reactor is composed of the pot body, pot cover, agitator, electric heating oil jacket, support and transmission unit, shaft seal unit, oil overflow trough, etc., and is equipped with electric heating rods and temperature and pressure measuring instruments. (See Figures 1 and 2.) Due to the varying production processes and operating conditions among users, the type of agitation generally includes anchor, paddle, turbine, propeller, or frame. The bearing seat comes in either suspended or supported types. The jacket is internally filled with thermal medium cylinder oil, heated by electric heating rods, and features openings for oil inlet, outlet, overflow, venting, and connections for electric heating rods and temperature measurement. The jacket's outer wall is welded with supports, and the pot body has an outlet for discharging material.
