Fluid medium heating system based on solid heat storage electric boiler

Abstract

The invention discloses a fluid medium heating system of a solid heat storage electric boiler, which comprises a solid heat storage electric boiler group, the solid heat storage electric boiler group includes two parallel solid heat storage electric boilers; The inlet pipe; the discharge pipe connected with the outlet of the solid heat storage electric boiler; the discharge pipes of the two solid heat storage electric boilers are respectively connected to the opposite sides of the shell side of the heat exchanger; the heat exchange medium is gas and / or liquid. The heating system of the present invention is completely based on the solid heat storage electric boiler as the heating unit of the heat exchange medium, which can be used such as gas and liquid as the heat exchange medium, and has wider applicability; the difference between the two sets of solid heat storage electric boilers and the heat exchanger is used. Arrangement, when two electric boilers are turned on at the same time, it can ensure that the two tubes are heated evenly, which improves the heat exchange effect.

Description

technical field [0001] The invention relates to the technical field of heating systems, in particular to a fluid medium heating system based on a solid heat storage electric boiler. Background technique [0002] Heating is the main means for people to resist the severe cold. In the peak heating season, the coal-fired combined heat and power units of domestic coal-fired power plants achieve this purpose by increasing the power generation in order to have a sufficient amount of heat supply. The contradiction of power grid peak regulation. [0003] In the prior art, the Chinese utility model patent with the authorized announcement number CN209196963U and the application number 201822083912.6 titled "A Comprehensive System for Heating Boiler Feed Water or Reheating Steam by a Solid Thermal Storage Electric Boiler" discloses a comprehensive system, which The air is heated by the air preheater and the solid thermal storage electric boiler, and the heated high-temperature air is u...

AI Technical Summary

Problems solved by technology

[0004] However, after practical application and careful research, the disclosed technology has certain limitations:

[0005] S1. Due to the introduction of the air preheater, the heating medium can only be gas, and the thermal power plant has less heat medium in the form of gas, which needs to be temporarily produced by the air preheater, so it brings some inconvenience;

[0006] S2. According to the different distribution of the connection position between the shell side structure of the heat exchanger and the intake pipe, the medium in the inner tube side is heated unevenly
