An energy-saving kang system based on pulsating heat pipes to recover waste heat

Abstract

The invention discloses an energy-saving heated brick bed system based on pulse heat pipe recovery afterheat. The energy-saving heated brick bed system comprises a heated brick bed body, a smoke settlement chamber and a pulse heat pipe heat exchange system, wherein a stove opening and a stove smoke outlet are formed in the heated brick bed body; the pulse heat pipe heat exchange system comprises a smoke chamber, a heat exchange chamber and a plurality of pulse heat pipes; the smoke chamber is arranged below the heat exchange chamber; a smoke inlet and a smoke outlet are respectively formed in two ends of the smoke chamber; the smoke inlet is connected with the stove smoke outlet; a condensed water outlet is formed in the bottom of the smoke chamber; a water inlet and a water outlet are respectively formed in two ends of the heat exchange chamber; the water inlet is connected with a running water pipe, and the water outlet is connected with a kitchen water tank; the multiple pulse heat pipes form a closed loop; evaporation sections of the pulse heat pipes are positioned in the smoke chamber, and condensation sections of the pulse heat pipes are positioned in the heat exchange chambers; furthermore, the smoke chamber and the heat exchange chamber is separated through a heat insulation partition plate. The energy-saving heated brick bed system recycles smoke afterheat by a pulse heat pipe technology and fully makes use of low-level heat, so that the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a system and a method for recovering waste heat of flue gas by settling of flue gas, in particular to an energy-saving kang system based on pulsating heat pipe technology to improve kang and make it energy-saving. Background technique [0002] Since the 1990s, with the continuous development of the economy, the contradiction between my country's energy supply and demand has been increasing, and the problem of energy shortage has emerged. According to calculations, in order to ensure an average annual GDP growth rate of more than 7%, my country faces the pressure of maintaining an annual increase of about 4% in energy supply. By 2050, my country will become the world's largest energy-consuming country, of which more than 96% is energy consumption of buildings. In rural areas, the problem of heating in winter is particularly serious, and heating energy consumption in northern rural areas accounts for 56% of the country's total. ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem of direct emission of flue gas during the use of kangs in the rural areas of Northeast my country, in order to make full use of the existing facilities and energy in the countryside, the present invention provides an energy-saving kang system based on pulsating heat pipes to recover waste heat, and recovers smoke through pulsating heat pipes Gas waste heat, without additional energy consumption, the waste heat in the flue gas directly discharged from the chimney is recovered and fully utilized, so as to save energy, protect the environment, and reduce smog.
