Technical Field

[0002] Magnesium carbonate is an inorganic substance with the chemical formula MgCO3. It is usually a white granular powder and is easily soluble in water. The high temperature resistance of magnesium carbonate makes it suitable for making fireproof and heat-insulating materials. In addition, magnesium carbonate is also commonly used as an oxidant, bleaching agent, catalyst, disinfectant, etching agent, wool shrinkage-proof agent and sewage treatment agent.

[0003] There are many methods for synthesizing magnesium carbonate products in factory workshops, including but not limited to dolomite carbonization method, brine carbonization method, brine soda ash method, brine carbon ammonium method, magnesite carbonization method, magnesia double decomposition method, asbestos tailings carbonization method, etc. Although different synthesis methods use different raw materials and production methods, they all require the step of adding water and pyrolysis, so the heating device is an indispensable device used in the synthesis process of magnesium carbonate products.

[0004] After massive searches, it was found that in the prior art, such as the publication number CN216946239U, an energy-saving heating device for synthesizing magnesium carbonate with a large apparent specific volume, relates to the technical field of heating devices for chemical synthesis, comprises a horizontally arranged square base, a vertically arranged reaction cylinder is fixedly connected to the center of the upper surface of the square base; the upper end of the reaction cylinder is opened, a feeding funnel is fixedly provided in the opening, the feeding funnel is in the shape of an inverted cone, and a material port cover is provided at the upper end of the feeding funnel; a heating box is fixedly connected to the inner bottom surface of the reaction cylinder, a multi-stage coil is connected to the electric heating box, and a plurality of electrically controlled check valves are provided on the multi-stage coil for controlling the connection and isolation of the multi-section coil; a connecting port is provided on the side wall of the reaction cylinder close to the lower end surface, and a horizontally arranged drain pipe is fixedly connected in the connecting port. The utility model solves the problem that the heating range of the multi-stage coil and the liquid level do not match each other during the use of the heating device for the synthesis of large apparent specific volume magnesium carbonate in the traditional technology, resulting in increased energy consumption and increased production costs. Although this method can heat the magnesium carbonate reactor evenly, it cannot control the temperature of the reactor, and further improvement is needed for this purpose.
