Description
Technical field
the utility model relates to a kind of gypsum calcining apparatus, particularly a kind of indirect heating type gypsum calcining apparatus.
Background technology
the desuifurized i.e. desulfurated plaster of thermal power plant, can produce plaster of Paris after calcined dehydration.But existing gypsum calcining apparatus generally adopts high temperature heat source to carry out high-temperature calcination, and production cost is higher; And the gypsum quality fluctuation of high-temperature calcination is comparatively large, and the coal-fired high temperature heat source produced and desulfurated plaster easily affect the visual appearancies such as the whiteness of gypsum after directly contacting and calcining, and cause the second-rate of gypsum.In addition, in order to obtain high temperature or high pressure thermal source, the general method adopting coal combustion at present; And sulfurous gas, carbonic acid gas and oxynitride can be produced in burning of coal process, cause environmental pollution.Therefore, existing gypsum calcining apparatus also exists that production cost is higher, gypsum quality is poor and the problem of environmental pollution.
Utility model content
the purpose of this utility model is, provides a kind of indirect heating type gypsum calcining apparatus.The utility model can not only reduce production cost, improves gypsum quality, also has the advantage of environmental protection.
the technical solution of the utility model: indirect heating type gypsum calcining apparatus, comprises inner barrel, inner barrel inwall is connected with some well heaters arranged that is inclined upwardly, is also provided with agitator in the middle part of inner barrel; Be arranged with outer cylinder body outside described inner barrel, the top of outer cylinder body side is provided with thermal source import, and the bottom of outer cylinder body is provided with thermal source outlet.
in aforesaid indirect heating type gypsum calcining apparatus, described inner barrel top is provided with cover plate, cover plate is provided with charging opening and the mouth that gathers dust.
in aforesaid indirect heating type gypsum calcining apparatus, described outer cylinder body side is provided with the different access hole of some height, facilitates the inspection and maintenance of each hot-plate, agitator, and the bottom of outer cylinder body side is also provided with discharge port, can the discharging of continous way nature.
in aforesaid indirect heating type gypsum calcining apparatus, the height of described inner barrel 1 is higher than the height of outer cylinder body 4, and the mounting height of well heater 2 in inner barrel 1 is lower than the height of outer cylinder body 4.
compared with prior art, the utility model improves gypsum calcining apparatus, first by charging opening, desulfurated plaster is put into inner barrel, then send into heat by thermal source import and pass to inwall and the well heater of inner barrel, desulfurated plaster is transferred heat to again by the inwall of inner barrel and well heater, realize indirect heating type calcining, calcining temperature is lower, improves gypsum quality, the upper end of the inwall of inner barrel can be dried desulfurated plaster, when desulfurated plaster falls to well heater, can move along the well heater tilted towards the inwall place of inner barrel, carry out mechanical stirring by agitator simultaneously, the evaporation of the moisture in desulfurated plaster is coordinated to make desulfurated plaster occur Fludized boiling in inner barrel, carry out fluidized calcination, calcining effect can not only be improved, and it is lower to the temperature requirement of the required thermal source of calcining, in can using, low temperature or in, low pressure thermal source is calcined, avoid the use of coal in conventional calcination device, reduce production cost, also there is the advantage of environmental protection.The material pressure that the material calcined in the utility model can produce by the desulfurated plaster added continuously, discharges continuously from discharge port, realizes the automatization calcining of continous way, improves overall production efficiency.Therefore, the utility model can not only reduce production cost, improves gypsum quality, also has environmental protection and the high advantage of production efficiency.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-inner barrel, 2-well heater, 3-agitator, 4-outer cylinder body, the import of 5-thermal source, 6-thermal source outlet, 7-cover plate, 8-charging opening, 9-gathers dust mouth, 10-access hole, 11-discharge port.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.Indirect heating type gypsum calcining apparatus, forms as shown in Figure 1, comprises inner barrel 1, inner barrel 1 inwall is connected with some well heaters 2 arranged that is inclined upwardly, is also provided with agitator 3 in the middle part of inner barrel 1; Be arranged with outer cylinder body 4 outside described inner barrel 1, the top of outer cylinder body 4 side is provided with thermal source import 5, and the bottom of outer cylinder body 4 is provided with thermal source outlet 6.
described inner barrel 1 top is provided with cover plate 7, cover plate 7 is provided with charging opening 8 and the mouth 9 that gathers dust; Described outer cylinder body 4 side is provided with the different access hole of some height 10, and the bottom of outer cylinder body 4 side is also provided with discharge port 11; The height of described inner barrel 1 is higher than the height of outer cylinder body 4, and the mounting height of well heater 2 in inner barrel 1 is lower than the height of outer cylinder body 4.
principle of work: first pass through thermal source import 5 to transfer of heat in inner barrel 1, then in inner barrel 1, the desulfurated plaster needing calcining is added by charging opening 8, dried by the inwall in inner barrel 1 and upper portion heater 2 pairs of desulfurated plasters, naturally having fallen to drying and having arrived middle part and lower heater 2 place along with desulfurated plaster; Due to acclivitous on well heater 2, so desulfurated plaster can move along the well heater 2 tilted to the inwall direction of inner barrel 1, then the inwall of inner barrel 1 and well heater 2 pairs of desulfurated plasters carry out indirect heating type calcining; Meanwhile, when indirect heating, agitator 3 rotates, and carries out mechanical stirring to desulfurated plaster, and the moisture evaporation coordinating indirect heating to produce forms Fludized boiling, thus desulfurated plaster is carried out to the fluidized calcination of indirect heating type.After having calcined, the material pressure that the material calcined can produce by the desulfurated plaster added continuously, discharges continuously from discharge port 11, realizes the automatization calcining of continous way, improves overall production efficiency.The utility model can also calcine the plaster of paris, phosphogypsum, titanium gypsum etc., and calcining principle is the same.
