Waste heat utilizing hot-blast stove

Abstract

A waste heat utilizing hot-blast stove comprises the following parts: a stove chamber, wherein an air inlet and an air return port are formed in the side face, an in-stove-chamber air inlet is formedin the bottom of the inner side, and an in-stove-chamber air return port is formed in the top of the inner side; a heat storage chamber that is arranged on the side face of the stove chamber, whereinan air inlet is formed in the top, an air outlet is formed in the bottom and communicated with the air inlet of the stove chamber, and an exhaust pipe is further arranged; a water storage tank that isused for waste heat recovery and arranged on the side face of the stove chamber and the front face of the heat storage chamber, and the exhaust pipe penetrates through the axis of the water storage tank; a burner that is used for heating the heat storage chamber and is arranged on the outer side surface of the heat storage chamber; a high-temperature circulating fan that is arranged at the top ofthe heat storage chamber, wherein a first end is communicated with the heat storage chamber air inlet, and a second end is communicated with the stove chamber air return port. By the adoption of thehot blast stove, surplus heat generated by the burner can be stably recycled, heat output of the heat storage chamber can be stabilized, overall energy consumption is reduced, the use cost of equipment is reduced, the startup and shutdown frequency of the burner is reduced, and the service life of the burner is prolonged.

Description

technical field [0001] The invention relates to the field of hot blast stoves, in particular to a hot blast stove utilizing waste heat. Background technique [0002] At present, as a thermal power machine, hot blast stoves have been widely used in many fields in our country. It has become a replacement product for electric heat sources and traditional steam power heat sources. It is realized by heated high-temperature air. Existing hot blast stoves are mostly built with bricks, fixed, and bulky, with high investment costs and a waste of money. They are disposable equipment and cannot be moved, which limits production. [0003] China Publication Patent No. CN 208887105U, published on May 21, 2019, the utility model name hot blast stove, this utility model discloses a hot blast stove, which belongs to the technical field of hot blast stove equipment, including a heat storage chamber, the side of the heat storage chamber A hot air pipe is connected to the wall, and a connecti...

AI Technical Summary

Problems solved by technology

[0005] The present invention is designed for the waste of energy caused by excess heat discharged from the combustion exhaust gas when the existing hot blast stove is heated by the combustion chamber. The hot blast stove with waste heat recovery system is added on the basis of the original hot blast stove.
