Electrically heated reaction kettle

Electrically heated reactor

Overview

Electrically heated reactors are primarily used in the petrochemical, chemical, rubber, pesticide, dye, and food industries, serving as vessels for processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation, including reactors, reaction vessels, decomposing kettles, and polymerizers, etc. Materials typically include stainless steel and carbon steel. These 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, agitator, 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 agitation types generally include anchor, paddle, worm gear, pusher, 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 is made up of the lid, cylinder, jacket, agitator, shaft seal transmission device, and support. It is suitable for various organic compounds in decomposition, synthesis, cracking, polymerization, and esterification reactions.

Heating methods include electric, oil, gas, water heating (or cooling), and open flame heating. Jacket types are jacketed and semi-tubular, with jacketed oil heating types featuring flow guidance devices. Agitation types generally consist of paddle, anchor, frame, ribbon, and scraper styles. High-speed models include dispersal impeller, turbine, high-shear, and propeller designs, allowing customers to choose based on their process requirements. Transmission types include standard motors, explosion-proof motors, electromagnetic speed control motors, and inverters. Heat exchangers come in trochoid pinion, worm gear, and planetary stepless variable speed designs. Shaft seals are available in standard water-cooled filling, combined PTFE filling, and mechanical seals. Discharge types include ball valves and lower expansion valves.

Equipment Features

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

Used in oil, chemical, rubber, pesticide, dye, food industries, for processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. It relies on thorough mixing of reactants and requires a stirrer for effective heating, cooling, liquid extraction, and gas absorption. We can also design and process external coil reactors for our clients.

Equipment Categories

Jacketing types include jacketed and semi-tubular, with jacketed oil heating types featuring flow guides. Mixing methods commonly include paddle, anchor, frame, helical, and scraper types. High-speed models include scatter impeller, turbine, high-shear, and propeller types, 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 infinite variable speed types. Shaft seals are typically water-cooled packed, combined packed, and mechanical sealed.

The reactor consists of a vessel body, cover, stirrer, electrically heated oil jacket, support and transmission device, shaft seal, overflow sump, etc., and is equipped with electric heating rods and temperature and pressure measuring instruments. (See Figures 1 and 2.) Due to varying production processes and operating conditions among users, the type of stirrer generally includes anchor, paddle, turbine, propulsion, or frame. The bearing seat is available in either suspended or supported styles. The inner sleeve contains heat medium cylinder oil, which is heated by electric heating rods. The jacket features inlet and outlet oil, overflow, vent, electric heating rod, and temperature measuring pipe openings. The jacket's outer wall is welded with brackets, and the vessel bottom is equipped with a discharge port.
