Boiler heat recovery device

Abstract

The invention discloses a boiler heat recovery device. The boiler heat recovery device is composed of a box body and a heat pipe, a clapboard is arranged inside the box body and divides the box body into two layers, the upper layer is a water box, the lower layer is a wind box, and the heat pipe which the two ends are located in the water box and the wind box correspondingly is fixed to the clapboard; a wind inlet and a wind outlet are formed in the two sides of the box body, the wind inlet of the wind box is connected with a smoke discharge pipe of a boiler, a water inlet pipe and a water outlet pipe are arranged on the water box, the water inlet pipe is connected with a running water pipe, and a water storage box is connected to the water outlet pipe; the bottom of the water storage box is connected with a water pump through a water pipe, and a water outlet of the water pump is connected with a tee; and one end of the tee is joined up a domestic water pipeline of an industry through a pipeline, and the other end of the tee is joined up a water inlet pipeline through the pipeline. The boiler heat recovery device achieves preheating of water entering into the boiler, reduces usage of energy sources of heating the boiler, improves the usage efficiency of the energy sources, and reduces heat pollution and smoke pollution of environment of high-temperature smoke.

Description

technical field [0001] The invention relates to the field of industrial boilers, in particular to a boiler heat recovery device. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . Boilers are divided into hot water boilers, steam boilers, heat transfer oil boilers, etc. according to their functions. At present, steam boilers are widely used in industrial production, restaurants, large-scale living communities and other enterprises. When many enterprises use boilers, they usually discharge the hot exhaust gas from the boiler directly into the atmosphere after passing through the chimney. The temperature of the exhaust gas discharged from the steam boiler is quite high, usually between 200...

AI Technical Summary

Problems solved by technology

The temperature of the exhaust gas discharged from the steam boiler is quite high, usually between 200°C and 300°C, and it is directly discharged into the atmosphere. On the one hand, it will cause serious heat waste and low energy utilization; on the other hand, due to insufficient combustion or heating The fuel is coal and other reasons make the exhausted hot tail gas contain SO 2 , NO X , smoke and other pollutants, causing serious pollution to the atmosphere and the environment
