Abstract
The utility model discloses an RSP decomposition furnace, which comprises a precombustion chamber and a decomposition chamber connected with the lower end of the precombustion chamber. A first material inlet and a second material inlet installed symmetrically are provided on top of the precombustion chamber. The materials which are heat changed and decomposed by the preheater enter the precombustion chamber in two ways through the two symmetrical material inlets installed on top of the precombustion chamber, and form materials curtain which protects the indoor wall and ceiling from forming high temperature area and damaging refractory material. The materials are mixed and decomposed thoroughly in the precombustion chamber. The utility model can increase the kiln decomposition rate to about 94%, avoid collapsing of materials in the decomposition chamber, and enhance unit-hour output by about 20%.
Description
Technical field
The utility model relates to the cement industry technical field, particularly relates to a kind of reinforcement suspended preheater (Reinforced Suspension Preheater, RSP) dore furnace.
Background technology
In the clinker production line, usually adopt the outer decomposition technique of new type dry kiln at present, use in the process of RSP dore furnace, go into the kiln raw material and divide two parts blanking after go into kiln whirlwind tube C4 through preheater heat exchanges decomposition at different levels, one the tunnel goes into kiln through going into kiln whirlwind tube C5 through precombustion chamber again to decomposition chamber, and kiln is directly gone into through going into kiln whirlwind tube C5 again to the decomposition chamber middle and lower part in another road.In this process, the material that enters precombustion chamber after the sub-material is few, and the tail coal burning is mainly carried out in precombustion chamber, cause the pre-burning indoor temperature too high, very easily burn and collapse refractory brick and water material feeding, must stop to build by laying bricks or stones again after the kiln cooling, could continue production process, make that the entire equipment running rate is low, the recondition expense height; The material that enters the decomposition chamber lower middle portion can not get abundant decomposition, even the partial material slump is arranged, and directly into kiln, causes the raw material resolution ratio low, influences the kiln unit-hour output, can not reach to produce operation, and every cost increases.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is how to improve the combustion rate of precombustion chamber material, avoids the interior refractory brick of precombustion chamber and waters burning of material feeding, improves the resolution ratio of the raw material that enter decomposition chamber, avoids the slump of material in the decomposition chamber.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of RSP dore furnace, it comprises: precombustion chamber and the decomposition chamber that is connected with described precombustion chamber lower end, and described precombustion chamber top is provided with first feeding mouth and second feeding mouth, and described first feeding mouth and second feeding mouth are symmetrical arranged.
In the above-mentioned RSP dore furnace, be provided with burner in the described precombustion chamber, described burner is arranged between described first feeding mouth and second feeding mouth.
In the above-mentioned RSP dore furnace, also comprise: mixing chamber, be arranged on described decomposition chamber below, be connected by going into kiln whirlwind tube with described decomposition chamber.
In the above-mentioned RSP dore furnace, described precombustion chamber bottom is provided with air inlet.
(3) beneficial effect
In the RSP dore furnace that technique scheme provided; by the feeding mouth of two symmetries is set at the precombustion chamber top; make material after the preheater heat exchange is decomposed be divided into two-way and enter precombustion chamber; form the material curtain in precombustion chamber, protection indoor wall and ceiling do not form high-temperature area, do not damage refractory material; and material is abundant mixed decomposition in precombustion chamber; raising is gone into the kiln resolution ratio and is reached about 94%, avoids the slump of material in the decomposition chamber, finally improves unit-hour output about 20%.
Description of drawings
Fig. 1 is the structural representation of the RSP dore furnace of the utility model embodiment.
Wherein, 1: precombustion chamber; 2: decomposition chamber; 3: the first feeding mouths; 4: the second feeding mouths; 5: air inlet; 6: burner.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 shows the structural representation of the RSP dore furnace of the utility model embodiment, this RSP dore furnace comprises: precombustion chamber 1 and the decomposition chamber 2 that is connected with described precombustion chamber 1 lower end, described precombustion chamber 1 top is provided with first feeding mouth 3 and second feeding mouth 4, and described first feeding mouth 3 and second feeding mouth 4 are symmetrical arranged; The material of being convenient to after the preheater heat exchange is decomposed enters precombustion chamber 1 through first feeding mouth 3 and second feeding mouth 4, and can fully mix; Decomposition chamber 2 belows are connected with mixing chamber by going into kiln whirlwind tube.Be provided with burner 6 in the described precombustion chamber 1, described burner 6 is arranged between described first feeding mouth 3 and second feeding mouth 4, is convenient to the abundant burning of material.Be provided with air inlet 5 in precombustion chamber 1 bottom, air inlet 5 is provided with 2 in the present embodiment, is symmetrical arranged, and by the speed and the flow of air inlet control valve control air intake, is convenient to control the abundant burning of tail coal and the abundant mixing of material.
As can be seen from the above embodiments; the utility model embodiment is by being provided with the feeding mouth of two symmetries at the precombustion chamber top; make material after the preheater heat exchange is decomposed be divided into two-way and enter precombustion chamber; form the material curtain in precombustion chamber, protection indoor wall and ceiling do not form high-temperature area, do not damage refractory material; and material is abundant mixed decomposition in precombustion chamber; raising is gone into the kiln resolution ratio and is reached about 94%, avoids the slump of material in the decomposition chamber, finally improves unit-hour output about 20%.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
