The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, grate-cooler of the present utility model comprises housing 1 and the grate 2 that is positioned at described housing 1, and housing 1 has refractory material inner-wall 18.Described grate 2 is used for accepting and transported material 13, and described grate 2 comprises feed end 5 and discharge end 6, and the below of described grate 2 forms the air compartment 7 to grate 2 blows cold air.Described housing 1 is provided with vertical shaft 3 and lingering remnants of past customs air outlet 4, and described vertical shaft 3 is positioned at the top of the feed end 5 of described grate 2, and described lingering remnants of past customs air outlet 4 is positioned at the top of the discharge end 6 of described grate 2.Vertical shaft 3 can be connected with kiln and dore furnace, for providing Secondary Air to kiln, to dore furnace, provides tertiary air.When the air quantity in grate-cooler remains in addition except supply Secondary Air, tertiary air and UTILIZATION OF VESIDUAL HEAT IN, remaining wind is drawn out of from lingering remnants of past customs air outlet 4, after the lingering remnants of past customs is drawn out of, through dedusting and purification, enters in atmosphere.
In the utility model, in the space that described housing 1 and described grate 2 surround, be also provided with aquaporin, the described aquaporin of crossing is between the theoretical pressure balanced surface 16 and lingering remnants of past customs air outlet 4 of described grate-cooler.The theoretical pressure balanced surface of grate-cooler refers to, the blower fan at vertical shaft 3 places and with the effect of the blower fan of lingering remnants of past customs air outlet 4 under, a side at theoretical pressure balance face 16, air flows to the direction of vertical shaft 3, opposite side at theoretical pressure balance face 16, air flows to the direction of lingering remnants of past customs air outlet 4 and/or UTILIZATION OF VESIDUAL HEAT IN air outlet 17, as shown in the arrow in Fig. 1.Grate-cooler is when design completes, and the parameter of its each blower fan and other parameters are decided, and the position of its theoretical pressure balanced surface 16 is also fixed.Therefore, the position of " the theoretical pressure balanced surface " of grate-cooler is that those skilled in the art can determine.Certainly, along with the variation of Air Flow in grate-cooler, actual pressure balance face can move near the position of theoretical pressure balance face 16, but position that can deviation theory pressure balance face 16 is far.
Crossing aquaporin and can be the passage on the refractory material inner-wall 18 that is opened in described housing 1, can also be to arrange or be lifted on the water pipe 8 on refractory material inner-wall 18 along refractory material inner-wall 18.In the present embodiment, on the roof of refractory material inner-wall 18 and sidewall, be equipped with the water pipe 8 of the roundabout bending of at least one row.As shown in Figure 3, cold water enters from water inlet 14, in mobile process, with high-temperature flue gas generation heat exchange, and is subject to the heat radiation of high-temperature material 13, when flowing out from delivery port 15, has been the hot water that temperature is higher.The water pipe 8 of roundabout bending can increase the area of heat exchange and participate in the water yield of heat exchange, certainly, the water pipe 8 of the roundabout bending of many rows also can be set as required on roof and sidewall, to utilize more fully waste heat.
Grate-cooler of the present utility model, owing to being provided with aquaporin in housing 1, water can obtain heating in grate-cooler, can utilize fully the heat of material 13 radiation and the heat of high-temperature flue gas.High-temperature flue gas can reach 400 ℃ of left and right in water pipe 8 mean temperature around, and the water of crossing in aquaporin can be heated to higher temperature rapidly, thereby has improved the efficiency of UTILIZATION OF VESIDUAL HEAT IN.Cross water in aquaporin and not only can be used for generating and also can be used for other purposes, as worker's individual water.Meanwhile, the flue gas in grate-cooler has obtained sufficient heat exchange, and the temperature of the lingering remnants of past customs of discharging at lingering remnants of past customs air outlet 4 also can correspondingly reduce, thereby the udst separation of the lingering remnants of past customs is more easily carried out.
By crossing aquaporin, be arranged between the theoretical pressure balanced surface 16 and lingering remnants of past customs air outlet 4 of grate-cooler, can prevent that aquaporin from affecting the supply of grate-cooler to Secondary Air and tertiary air.
In the present embodiment, the discharge end 6 of described grate 2 is provided with bulk materials 13 is carried out to broken disintegrating machine 9, between described water pipe 8 and described disintegrating machine 9, be provided with chain curtain 10, can prevent that material 13 fragments from touching on described water pipe 8 and damage water pipe 8, as preferably, described chain curtain 10 is between described water pipe 8 and described lingering remnants of past customs air outlet 4.
In the present embodiment, described housing 1 offers UTILIZATION OF VESIDUAL HEAT IN air outlet 17 between described theoretical pressure balanced surface 16 and lingering remnants of past customs air outlet 4.Flue gas through heat exchange can be extracted out and carried out UTILIZATION OF VESIDUAL HEAT IN again from UTILIZATION OF VESIDUAL HEAT IN air outlet 17, can utilize more fully heat energy.
As preferably, described housing 1 is also provided with in described theoretical pressure balanced surface 16 positions the insulated wall 11 of keeping out the wind, as shown in Figure 1, the described insulated wall 11 of keeping out the wind from the roof of described refractory material inner-wall 18 to downward-extension, and described in keep out the wind and there is the aisle space 12 that allows material 13 and flue gas to pass through between the lower end of insulated wall 11 and described grate 2.
At the feeding end of grate 2, the temperature of material 13 is the highest, and in the process of carrying, material 13 produces heat exchange with the cold air being blown in grate-cooler, and its temperature reduces gradually.Therefore, in grate-cooler, higher near the position temperature of vertical shaft 3 one end the closer to feeding end, lower the closer to the position temperature of discharge end 6.The insulated wall 11 of keeping out the wind arranging in theoretical pressure balance face 16 positions, can prevent that heat is radiated through the position away from vertical shaft 3 from the position near vertical shaft 3, thereby improved the temperature of the flue gas at vertical shaft 3 places, improved the Secondary Air that enters kiln and the temperature that enters the tertiary air of stove.In practice, the temperature that adds the flue gas at the rear vertical shaft of the insulated wall 11 of keeping out the wind 3 places has improved 100 ℃ of left and right than the temperature not adding while keeping out the wind insulated wall 11, take full advantage of the heat of high-temperature material, when providing more sufficient heat for the decomposition technique of the calcining in kiln and dore furnace the energy.
When actual theoretical pressure balanced surface and theoretical theoretical pressure balanced surface are when inconsistent, as actual theoretical pressure balanced surface moves to the left side in Fig. 1, the air capacity in the insulated wall of keeping out the wind 11 left sides is enough supplied Secondary Air and tertiary air, remaining air capacity can enter the space on insulated wall 11 right sides of keeping out the wind by aisle space 12, to carry out UTILIZATION OF VESIDUAL HEAT IN or to be discharged from.When actual theoretical pressure balanced surface moves to the right side in Fig. 1, the air capacity in the insulated wall of keeping out the wind 11 left sides is supplied Secondary Air and tertiary air not, and the space that the part air on the insulated wall of keeping out the wind 11 right sides can enter insulated wall 11 left sides of keeping out the wind by aisle space 12 is with Secondary Air and the tertiary air of replenishing the supply.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art in essence of the present utility model and protection domain, various modifications that the utility model is made or be equal to replacement and also drop in protection domain of the present utility model.
