Particle Electric Heater

Abstract

The invention relates to a particle electric heater, comprising: a particle tank for uniformly placing heat-conducting particles; the heat-conducting particles for conducting heat-conducting; a heat-exchanging coil, for realizing uniform heating of the flowing medium in the heat-exchanging coil through the heat-conducting particles; The tile is used to generate high temperature heat; the electric heating tube is used to provide energy for the electric heating tile; the first interface is used to make the flowing medium flow into the electric heater for heating; the second interface is used to heat the flow through the electric heater. The medium flows out; the temperature detector is used to detect the temperature of the flowing medium flowing out of the second interface in real time; the image scanner is used to scan the electric heater; the mouth of the particle tank is used to pour the thermally conductive particles out of the particles The tank is used to clean the thermally conductive particles; thus, the cleaning time of the thermally conductive particles can be determined by the dust adhesion rate, and the thermally conductive particles can be poured out of the particle tank for cleaning, which effectively ensures the thermal conductivity of the thermally conductive particles and improves the heat transfer efficiency of the electric heater.

Description

technical field [0001] The invention relates to the technical field of high temperature heat exchange and heating of particles, in particular to a particle electric heater. Background technique [0002] In the process of petroleum and petrochemical production, heat exchange, heating and heat preservation of flammable and explosive fluid media such as water, petroleum, natural gas, chemical and chemical raw materials, reagents, additives, etc. At present, several medium heat exchange methods such as water, steam, heat transfer oil, and antifreeze are used in the production process of petroleum, petrochemical, and natural gas chemical industries to heat the medium to be heated. These heat exchange methods have many disadvantages such as easy leakage, low boiling point and low temperature rise limit, and short aging life due to their own upper limit of temperature rise and their own liquid characteristics. It is not suitable for the production concept of safety, environmental ...
