Abstract
The utility model discloses a secondary smoke residual heat utilization system for a hot blast stove. The secondary smoke residual heat utilization system comprises a hot blast stove smoke inlet, an air preheater, a smoke connecting pipe, a flue and a chimney which are connected in sequence, wherein the air preheater consists of an upper cold air channel and a lower smoke channel. The secondary smoke residual heat utilization system for the hot blast stove is characterized in that a water preheater is connected in series in the flue and is internally provided with a water flow channel. By a method of adding one water preheater behind the original air preheater (namely the heat exchanger) of the hot blast stove, cold water or circulating water is heated, and the heated water can be used for bathing and warming in winter, so that the secondary utilization of smoke residual heat of the hot blast stove is realized, and thus the function of smoke of the hot blast stove are brought into full play.
Description
Technical field
The utility model relates to hot-blast stove UTILIZATION OF VESIDUAL HEAT IN technical field, specifically a kind of hot-blast stove fume waste heat second use system.
Background technology
The hot-blast stove that metallurgy, chemical industry, distillation system use; Generally all between 300 ℃ to 500 ℃, prior art is that a preheater (also can be called heat exchanger) is installed on the hot-blast stove fume pipeline to the flue-gas temperature that its burning produces, and the part heat is recycled; It utilizes method is exactly that preheating heat wind furnace itself burns coal gas and the combustion air that stove uses; Because traditional theory thinks that the fume afterheat that is lower than 180 ℃ does not have value, therefore, under the guidance of above-mentioned theory; The final exhaust gas temperature of traditional hot blast stove burning coal gas and combustion air preheater (heat exchanger) all designs at 180 ℃; Have even exhaust gas temperature is designed to 200 ℃, and this part heat wastes, and causing greatly, fume afterheat is not used.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of and can carry out the second use system to the hot-blast stove fume waste heat, and waste heat is increased second use, is used to heat bathing water or the recirculated water of warming oneself, and realizes energy-saving and emission-reduction.
The utility model solves the technical scheme that its technical problem takes: a kind of hot-blast stove fume waste heat second use system; Comprise the hot-blast stove fume inlet, air preheater, flue gas tube connector, flue and the chimney that connect successively; Said air preheater comprises the cold air channel on top and the exhaust gases passes of bottom; It is characterized in that water preheater is gone in series connection in said flue, have water stream channel in the said water preheater.
Said water preheater horizontal arrangement.
Said water preheater is vertically arranged.
The beneficial effect of the utility model is: through increase the method for a water preheater again in the original air preheater of hot-blast stove (heat exchanger) back; Heat cold water or recirculated water; Can heated water be used for bathing and warming; Realized through this method utilizing the second time of hot-blast stove fume waste heat, given full play to the effect of hot-blast stove fume waste heat, realized the energy-saving and cost-reducing of enterprise and society and reduce CO2 emission with this.
Description of drawings
Fig. 1 is one of layout sketch map of the utility model;
Fig. 2 be the utility model sketch map two;
Among the figure: 1 hot-blast stove fume inlet, 2 air preheaters, 21 cold air channels, 22 exhaust gases passes, 3 flue gas tube connectors, 4 flues, 5 water preheaters, 6 chimneys.
The specific embodiment
Like Fig. 1, shown in Figure 2,
A kind of hot-blast stove fume waste heat second use system; Comprise the hot-blast stove fume inlet 1, air preheater 2, flue gas tube connector 3, flue 4 and the chimney 6 that connect successively; Air preheater comprises the cold air channel 21 on top and the exhaust gases passes 22 of bottom, and the exhaust gases passes 22 of cold air channel 21 and bottom is not communicated with each other, carries out the transfer of heat through heat transfer medium; Water preheater 5 is gone in series connection in flue 4, has water stream channel in the water preheater 5.Above-mentioned air preheater and water preheater all belong to heat exchange equipment in the prior art, belong to existing equipment.Air preheater wherein also can use the gas preheating device to substitute, or even air, gas double pre-heating substitute, and these simple substitution all should fall into the protection domain of the utility model.
Said water preheater horizontal arrangement is like Fig. 1.Arrow is represented the flow direction of high-temperature flue gas and low temperature cold air (coal gas) respectively in the way.
Said water preheater is vertically arranged, like Fig. 2.
During work; The hot-blast stove fume inlet is arranged in the exhaust gases passes of the bottom of air preheater, cold air or gas entry and hot-air or gas exit are arranged in the cold air channel on the top of air or gas preheating device, the flue gas tube connector is arranged between air preheater and water preheater; Water preheater connects flue at the back; Flue connects chimney, in the both sides of water preheater cold water inlet, hot water outlet is arranged up and down perhaps, realizes the heating of water.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (3)
1. hot-blast stove fume waste heat second use system; Comprise the hot-blast stove fume inlet, air preheater, flue gas tube connector, flue and the chimney that connect successively; Said air preheater comprises the cold air channel on top and the exhaust gases passes of bottom; It is characterized in that water preheater is gone in series connection in said flue, have water stream channel in the said water preheater.
2. a kind of hot-blast stove fume waste heat second use according to claim 1 system is characterized in that said water preheater horizontal arrangement.
