Electrically heated reaction kettle

Electrically heated reactor

Overview

Electrically heated reaction vessels 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, including reactors, reaction vessels, decomposition kettles, and polymerizers, etc. The materials are generally stainless steel and carbon steel. Electrically heated reaction vessels are widely used in the chemical, food, natural flavoring, food additive, and light industry sectors.

Equipment Structure

Electrically heated reaction kettle is composed of kettle body, kettle lid, stirrer, jacket, support and transmission device, shaft seal device, etc. The material and aperture can be customized according to the user's process requirements. Made of 1Cr18Ni19Ti stainless steel plate, the stirring methods generally include anchor, paddle, worm gear, propulsion, or frame type. It is a cost-effective and easy-to-operate unit that heats the oil in the jacket directly with electric heating rods, achieving high heating temperatures. The reaction kettle is made up of kettle lid, cylinder body, 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 jacketed oil heating models featuring flow guidance devices. Agitation styles generally consist of paddle, anchor, frame, screw blade, and scraper types. High-speed models include diffuser 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 variable speed designs. Shaft seals are of the standard water-cooled packed, combined PTFE packed, and mechanical seal types. Discharge options include ball valves and butterfly 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.

Applied to oil, chemical, rubber, pesticide, dye, food industries, for processes like vulcanization, nitrification, hydrogenation, hydrocarbonation, polymerization, condensation, etc. It requires thorough mixing of reactants as a premise, and agitation equipment is necessary for processes such as heating, cooling, liquid extraction, and gas absorption to achieve optimal results. We can also design and process external jacketed reactors for customers.

Equipment Categories

Sleeve types include jacketed and semi-tubular, with jacketed oil heating models 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 designs, 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 types. Shaft seals are typically water-cooled packed, combined packed, or mechanical sealed.

The reactor is composed of the vessel body, lid, agitator, electric heating oil jacket, support and transmission device, shaft seal, and overflow oil trough, 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 types of agitation generally include anchor, paddle, turbine, propeller, or frame. The bearing seat comes in two types: suspended or supported. The inner sleeve contains heat medium cylinder oil, heated by electric heating rods, with openings for oil intake, discharge, overflow, venting, and heating rod and temperature measurement connections. The outer wall of the jacket is welded to the bracket, and the bottom of the vessel body features an outlet for discharging material.
