Description
Technical field
The utility model is about a kind of roasting assembly, in particular, and about a kind of desulphurization gypsum calcination device.
Background technology
Along with the fast development of China's gypsum industry in recent years, and the increasing of plastering, also stricter to the requirement of land plaster process.Existing terra alba progressively is divided into more different classification according to the requirement difference of subsequent applications, the demand that develops for satisfying the market simultaneously, just must develop the gypsum calcining apparatus of all kinds of special uses, to guarantee that each device is to the optimal adaptation state of raw material and the performance of raw material maximum value.
At present, more for the calciner of desulfurated plaster, mainly contain two classes with regard to its classification, the one, adopt traditional calciner, as fluidizing furnace etc.; The 2nd, adopt hot gas flow directly to contact and calcine; Because the desulfurated plaster particle concentrates on 30-100 microns, contain the attached water of 8-15%, directly adopt tradition to produce the method for terra alba, must consider to adopt the first oven dry device and method of calcining again, exist thermosteresis large, energy consumption is high, and the terra alba quality of producing is low, and the performance adjustment is difficult for; Though air-flow calcining heat exchange is fast, environmental protection pressure is large, and product is too fast time of coagulation, can not adapt to the calcining of desulfurated plaster raw material.
Summary of the invention
The utility model provides a kind of reasonable in design, desulphurization gypsum calcination device that heat exchange efficiency is high.
Desulphurization gypsum calcination device in the utility model comprises rotary calcining body of heater, at the body of heater head, charger and flue gas discharge case are installed, at the body of heater afterbody, feed box is installed, the body of heater afterbody passes the high-temperature flue gas Heat Room, axially be evenly equipped with heat transfer tube along body of heater on the circumference of inboard wall of furnace body, one end of heat transfer tube is communicated with the high-temperature flue gas Heat Room, the other end is communicated with the flue gas recirculation heat exchange jacket in being located at the body of heater head, be provided with cleaning apparatus in flue gas is discharged case, this cleaning apparatus includes cyclone dust removal machine and bag-type dust machine.
Described inboard wall of furnace body annular on the circumference that is positioned at the flue gas recirculation heat exchange jacket is evenly equipped with the first turning vane, is positioned at uniform the second turning vane of annular on the circumference of heat transfer tube at inboard wall of furnace body.
Roasting assembly in the utility model is by controlling the processing parameters such as smoke inlet temperature, flow of flue gas speed, calcination time, just can reach the ratio of controlling half water or III type, thereby the terra alba of production different varieties, as building gypsum plaster or the fast solidifying terra alba of goods.
Description of drawings
Figure l is the structural representation of desulphurization gypsum calcination device in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is further described.
As shown in Figure 1, the roasting assembly in the utility model includes rotary calcining body of heater 1, is equipped with on body of heater 1 and supports 2 and drive unit (not shown) that can the body of heater rotation, and the right-hand member of body of heater 1 is the body of heater head, and left end is the body of heater afterbody.At the body of heater head, charger 3 and flue gas discharge case 4 are installed, at the body of heater afterbody, feed box 11 are installed, body of heater 1 left end is that the body of heater afterbody passes high-temperature flue gas Heat Room 9.In discharging case 4, flue gas is provided with medial rotation dusting machine and bag-type dust machine 10.What be uniformly distributed along the circumference on body of heater 1 inwall axially is provided with heat transfer tube 8, an end of heat transfer tube 8 and high-temperature flue gas Heat Room 9 UNICOMs, flue gas recirculation heat exchange jacket 5 UNICOMs of installing in the other end and body of heater head.
An end that is positioned at flue gas recirculation heat exchange jacket 5 at body of heater 1 inwall is evenly equipped with the first turning vane 6, and the desulfurated plaster that utilizes this first turning vane 6 can promote to enter body of heater 1 inside enters into afterbody from the head of body of heater 1.An end that is positioned at simultaneously heat transfer tube 8 in body of heater 1 inside is provided with the second turning vane 7, is used for pushing desulfurated plaster.
Need the right cream of desulfurization of calcining to enter in body of heater 1 by the charger 1 of body of heater head right-hand member, be provided with spiral propeller in charger 1 inside, can accelerate entering of desulfurated plaster, stir and to left end, promote by being arranged on the first uniform directing vane 6 of annular on flue gas recirculation heat exchange jacket 5 inwall circumference, and by flue gas recirculation heat exchange jacket 5, carrying out heat exchange and oven dry.Then enter in the body of heater 1 with heat transfer tube 8, the stirring by being fixed on body of heater 1 the second uniform turning vane 7 of annular between heat transfer tube 8 and stirring, make desulfurated plaster and heat transfer tube 8 carry out sufficient heat exchange, realizes pre-heating temperature elevation.When desulfurated plaster entered into 9 sections of the high-temperature flue gas Heat Rooms of body of heater afterbody, the temperature in body of heater 1 was the highest, generally can reach 1000 ℃ of left and right, at this section desulfurated plaster, just can realize calcining.Desulfurated plaster after calcining is by the second turning vane 7 and be fixed on circular blocking material plate 12 on inboard wall of furnace body between the second turning vane 7 and feed box 11, enters feed box 11, the disposable oven dry of completing desulfurated plaster, pre-heating temperature elevation and calcination process.
In said process, high-temperature flue gas is entered in heat transfer tube 8 by high-temperature flue gas Heat Room 9, move right, carry out sufficient heat exchange by heat transfer tube 8 and desulfurated plaster, the temperature of high-temperature flue gas is reduced gradually, enter the flue gas recirculation heat exchange jacket 5 of body of heater head, after again with desulfurated plaster, carrying out heat exchange, discharge case 4 by the flue gas that is arranged on the body of heater head and discharge.Because high-temperature flue gas does not contact with desulfurated plaster, and high-temperature flue gas and desulfurated plaster are by the sufficient heat exchange of heat transfer tube 8 and flue gas recirculation heat exchange jacket 3, the flue-gas temperature that flue gas is discharged case 4 discharges is low, dust content is low, and the dusting machine 10 that utilizes simultaneously flue gas to discharge in case 4 can effectively be removed dust.
In sum, roasting assembly in the utility model, its inner desulfurated plaster changes half water or III type gypsum phase grog into by two water gypsum after calcining, in the process of whole oven dry, pre-heating temperature elevation and calcining, by controlling the processing parameters such as smoke inlet temperature, flow of flue gas speed, calcination time, just can reach the ratio of controlling half water or III type, thus the terra alba of production different varieties, as building gypsum plaster or the fast solidifying terra alba of goods.
