Solid electrical thermal storage high-efficiency warm air anhydrous heating system

Abstract

The invention discloses a solid electrical thermal storage high-efficiency warm air anhydrous heating system which comprises an electric warm air device, an air blower, a heat preservation supply air duct and an air supply device. The electric warm air device comprises a heat preservation shell, a heat preservation buckle cover, a solid heat accumulator, a heating electrode, an air-air heat exchanger and an internal circulation variable frequency fan; the air-air heat exchanger comprises a heat exchange pipe, an upper mounting plate, a lower mounting plate and a separator; the air-air heat exchanger is externally hung on the side wall of the heat preservation shell; an inlet bellows and an outlet bellows are arranged at the front side of the heat preservation buckle cover; a communication box is arranged at the rear side of the heat preservation buckle cover; the separator divides a space among the heat preservation shell, the heat preservation buckle cover, the upper mounting plate and the lower mounting plate into a U-shaped air duct; a closed circulating air duct is formed between the solid heat accumulator and the top and the bottom of the heat preservation shell and inside the heat exchange pipe; the electric warm air device is respectively connected with the air blower and the heat preservation supply air duct; the air supply device is independently distributed at the tail end of the heat preservation supply air duct. The solid electrical thermal storage high-efficiency warm air anhydrous heating system disclosed by the invention has the characteristics of freeze protection, cleanness, environmental-friendliness, low cost operation, safety, high efficiency and energy saving.

Description

technical field [0001] The invention relates to the field of heating, and in particular provides a solid electric thermal storage high-efficiency hot air anhydrous heating system, which is mainly used in the heating field of northern cities (factories, warehouses, shopping malls, etc.). Background technique [0002] The hot air heating system used in the northern heating industry has a good antifreeze effect because it uses hot air for heating instead of water system heating, and is adopted by a large number of factories, warehouses, and shopping malls. However, whether it is a hot air system in the form of direct, heat exchange, or heat storage, it uses solid fuel (coal, biomass, etc.), liquid fuel (oil, alcohol-based fuel, etc.) and gaseous fuel (gas, natural gas, etc.), Due to the air pollution produced by the combustion of solid fuel and liquid fuel, it has seriously caused smog, and many cities in the north have banned the use of it. Due to the high price of gas fuel, i...

Problems solved by technology

However, whether it is a hot air system in the form of direct, heat exchange, or heat storage, it uses solid fuel (coal, biomass, etc.), liquid fuel (oil, alcohol-based fuel, etc.) and gaseous fuel (gas, natural gas, etc.), The air pollution caused by the combustion of solid fuel and liquid fuel has seriously caused smog, and many cities in the north have banned the use of it. Due to the high price of gas fuel, it cannot be widely used in the heating field

In addition, due to the long transportation distance and high resistance, it is necessary to use a fan with a large power as the power source. Even so, the air supply distance at the end of the transportation pipeline is still very short, and the efficiency is low and the effect is not good.
