The invention discloses an efficient gas boiler energy recycling device. An air preheating mechanism and a waste gas heat exchange mechanism are included. The air preheating mechanism comprises a heat preservation cover, a heat absorbing pipe, a molecular sieve purifier, air pressure barrels and a servo motor. The heat absorbing pipe is coiled on the outer side of a boiler. The heat preservation cover is arranged on the outer side of the heat absorbing pipe. An exhaust pipe is arranged at the bottom end of the heat absorbing pipe. A first one-way valve is arranged on the outer side of the exhaust pipe. The top end of the heat absorbing pipe is connected with one side of the upper portion of the molecular sieve purifier. The two sides of the lower portion of the molecular sieve purifier are connected with the two air pressure barrels through two first connecting pipes correspondingly. The symmetric sides of the two air pressure barrels are connected with a dust purifier through second connecting pipes, and an air inlet is formed in the top of the dust purifier. The air preheating mechanism and the waste gas heat exchange mechanism are used for recycling the energy of the boiler, the gas boiler efficiency is greatly improved, the resource is saved, and waste capable of being prevented is avoided.
Description
technical field [0001] The invention relates to the field of boiler recovery and utilization devices, in particular to a high-efficiency gas boiler energy recovery and utilization device. Background technique [0002] Gas boilers include gas boiling water boilers, gas hot water boilers, gas steam boilers, etc. Among them, gas hot water boilers are also called gas heating boilers and gas bathing boilers. Gas boilers, as the name implies, refer to boilers whose fuel is gas. Electric boilers are the most economical in comparison, so most people choose gas boilers as boiler equipment for steam, heating, and bathing. [0003] The heat dissipation loss of the gas boiler furnace body includes the following aspects: 1. Generally, the surface temperature of the furnace body should not be higher than the ambient air temperature by 50°C. When the gas boiler is running, the surface temperature of the furnace wall, steel frame, pipes and other accessories is higher than the ambient temp...
