Hot blast stove

Abstract

The invention relates to the field of heating equipment, in particular to a hot blast stove. It includes a furnace body composed of a combustion chamber and a purification chamber. In the furnace body, there is an air intake passage connecting the combustion chamber and the purification chamber. On the side wall of the furnace body on one side of the combustion chamber, there is a gas For the burner, a high-temperature flue gas gate connected to the combustion chamber is vertically provided on the top of the furnace body on the side of the combustion chamber, and an exhaust pipe whose bottom end extends to the clean room is vertically provided on the top of the furnace body on the side of the clean room . It is simple in structure, reasonable in design and easy to operate. It provides a hot blast stove with its own purification of hot flue gas, which can improve the adequacy of burning raw coal such as lump coal and mixed coal, and can clean the polluted hot flue gas after the raw materials are burned. Purification does not require additional purification equipment, is more energy-saving and environmentally friendly, reduces equipment investment and maintenance costs, more effectively meets people's needs, and solves the problems existing in the prior art.

Description

Technical field: [0001] The invention relates to the field of heating equipment, in particular to a hot blast stove. Background technique: [0002] The hot blast stove is a kind of equipment used to provide high-temperature flue gas in the rotary indirect heating low-rank coal modification and upgrading system. Generally, the fuel used in hot blast stoves is mainly raw coal such as lump coal and mixed coal. However, when the existing hot blast stove burns raw coal such as lump coal and mixed coal in its interior, it is often easy to cause combustion due to large particles. Insufficient, the hot flue gas produced contains more dust. If these insufficiently combusted gases are directly discharged to the outside world, it will cause air pollution. Therefore, the necessary dust removal equipment is usually added to the existing hot blast stove combustion system. The hot flue gas is purified, but this not only increases the equipment investment, but also the follow-up maintenanc...

Generally, the fuel used in hot blast stoves is mainly raw coal such as lump coal and mixed coal. However, when the existing hot blast stove burns raw coal such as lump coal and mixed coal in its interior, it is often easy to cause combustion due to large particles. Insufficient, the hot flue gas produced contains more dust. If these insufficiently combusted gases are directly discharged to the outside world, it will cause air pollution. Therefore, the necessary dust removal equipment is usually added to the existing hot blast stove combustion system. Purify the hot flue gas, but this not only increases the equipment investment, but also the follow-up maintenance work of the equipment is more cumbersome, which increases the operating cost. Obviously, the existing hot blast stove cannot meet people's needs more effectively
