Abstract
The utility model relates to a coal burning hot air furnace, which is composed of a chain furnace and shell-and-tube heat exchanger. The heat exchanger is tightly connected to the part of the chain furnace, and the heat exchanger is provided with a tube pass and a shell pass. The tube pass of the heat exchanger is provided with a normal temperature air inlet and a hot air outlet, and the shell of the heat exchanger is provided with a high temperature air inlet and a flue air outlet. The rear part of the furnace cavity is provided with the high temperature flue air outlet, the high temperature flue air outlet of the chain furnace and the high temperature flue inlet of the shell pass of the heat exchanger are mutually communicated. The heat exchanger of the utility model is arranged above the chain furnace, characterized in compact structure and small ground occupying area, and in addition, because flue air moves on the shell pass of the heat exchanger, and air moves on the tube pass of the heat exchanger, the pipeline of the heat exchanger can not be blocked.
Description
The utility model relates to the heat exchanger of a kind of hot-blast stove, particularly a kind of coal-fired hot-blast stove.
In the prior art, coal-fired hot-blast stove is connected to form by stove and tubular heat exchanger, and hot-blast stove and heat exchanger are on sustained height, and the occupation of land face of this hot-blast stove is bigger; In addition, the high-temperature flue gas that comes out from burner hearth is the tube side that flows through heat exchanger, and the shell side that normal temperature air flows through heat exchanger is heated, owing to contain thin flue dust in the flue gas, has grown the phenomenon of easy generation plugging service time and influences use.
The utility model is in order to overcome above-mentioned deficiency, and it is little to propose a kind of floor space, coal-fired hot-blast stove that can plugging.
The utility model is realized with the following method.
Coal-fired hot-blast stove is connected to form by chain furnace and tubular heat exchanger, and heat exchanger is close to above chain furnace.Heat exchanger has tube side and shell side, and the tube side of heat exchanger has normal temperature air inlet and hot-blast outlet, and the shell side of heat exchanger has high-temperature flue gas inlet and flue gas outlet.There is the high-temperature flue gas outlet at the burner hearth rear portion of chain furnace, and the high-temperature flue gas outlet of chain furnace is connected with the high-temperature flue inlet of heat exchanger shell pass, and the flue gas outlet of heat exchanger shell pass leads to atmosphere, and the air intake of heat exchanger tube side leads to atmosphere.
During use, hot-blast outlet at the heat exchanger tube side connects an air-introduced machine, make the tube side of normal temperature air with air-introduced machine by heat exchanger, the high-temperature flue gas that allows mode chain furnace combustion produce passes through shell side, the normal temperature air heating by the heat exchanger tube side, the air after the heating is drawn from the hot-blast outlet of heat exchanger with air-introduced machine.
Heat exchanger of the present utility model is close to above chain furnace, and its compact conformation, floor space are little; Because flue is made the shell side of heat exchanger leave with rage, air is walked the tube side of heat exchanger, so can not stop up the pipeline of heat exchanger in addition.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 be coal-fired hot-blast stove partly cut open schematic diagram.
Among Fig. 1, coal-fired hot-blast stove is connected to form by chain furnace 1 and tubular heat exchanger 2, and heat exchanger 2 is close to above chain furnace 1.Chain furnace 1 has high-temperature flue gas outlet 11.Tubular heat exchanger 2 has shell side and tube side, shell side has high-temperature flue gas inlet 23 and flue gas outlet 24, tube side has normal temperature air inlet 21 and hot-blast outlet 22, and the high-temperature flue gas inlet 23 of heat exchanger 2 shell sides is connected with the high-temperature flue gas outlet 11 of chain furnace 1.
