Abstract
The utility model discloses a rotary roasting device comprising two static uniform heaters, a heating tube array, sealing devices, a rotary device and a conveyor. The sealing devices are disposed at two ends of the rotary device. The conveyor for conveying materials penetrates the sealing devices and conveys the materials into the rotary device. One static uniform heater is disposed outside each sealing device. The static uniform heaters are connected through the heating tube array axially penetrating the rotary device. The heating tube array is disposed in the lower middle of the rotary device and is independently fixed; the heating tube array never rotates with a kiln. The heating tube array is disposed in the lower middle of the kiln only and just occupies 40-60% of the inner space of the kiln, about half of the heating tube array is disposed inside the kiln, materials are saved, the influence on treatment capacity is low and investment cost of equipment is greatly lowered.
Description
Technical field
The utility model relates to a kind of revolution calciner, relates in particular to a kind of device of middle low temperature revolution calcining kiln.
Background technology
Middle low temperature revolution calcining kiln, because it can provide good mixed performance and efficient heat-transfer capability, can be adapted to the roasting of the multiple raw material of industry.
But because present revolution calcining kiln mostly exists following problem at 0～600 DEG C of temperature: what have does not add flight, material is in the motion of kiln inner bottom part, and heating surface is limited and be heated inhomogeneous; Heat medium (flue gas etc.) directly contacts with material, brings material secondary pollution, is unfavorable for the purification of reaction and product of roasting, has increased tail gas amount simultaneously; Be furnished with the rotary kiln of heating tubulation, tubulation is generally fixed on kiln wall and rotation of kiln, and is covered with most of kiln space, the difficulty that has increased sealing, causes seal structure complex, and indivedual tubulation is while breaking, must stop kiln could process, and is unfavorable for ordinary maintenance, has increased cost etc.
The existence of these problems has caused unstable product quality, and operation rate is low, and energy consumption is high, and cost is high.
Utility model content
The technical problem existing in order to solve prior art, the utility model specifically discloses a kind of device that turns round roasting.
The utility model adopts following technical proposals:
Turn round a device for roasting, comprise static soakage device, heating tubulation, sealing device, slewing equipment, conveying device; Described sealing device is located at the two ends of slewing equipment, conveying device for delivery of material is input to back material in assembling device through sealing device, and being respectively provided with an even hot charging of static state in sealing device outside puts, two even hot chargings of static state use the heating tubulation that axially runs through slewing equipment to connect between putting, heating tubulation is arranged on the middle and lower part of slewing equipment and fixing separately, and heating tubulation does not rotate with slewing equipment.
Inwall at described slewing equipment is furnished with flight.
Described heating tubulation accounts for 40%～60% of slewing equipment space.
Described conveying device is made up of feed bin and batcher, and the material in feed bin enters roasting in slewing equipment through batcher.
Described sealing device is shaft terminal contact type sealing.
Described slewing equipment is revolving drum, and front and back rolling ring plays supports cylindrical shell effect, and revolving drum inwall arranges flight.
Described static soakage device is semicircular cavities, and one end is thermal medium import or export, and the other end connects heating tubulation.
Described heating tubulation is static arrangement, runs through whole kiln body, does not rotate with the rotation of revolving drum.
The beneficial effects of the utility model are:
1) kiln inner tube wall is furnished with flight, can fully offer material, has avoided material only to move at kiln inner bottom part, limited and the inhomogeneous shortcoming of being heated of heating surface, can make material fully contact with thermal source by offering, and is heated evenly, increase heat exchange area, strengthened heat transfer effect.
2) heat medium (hot flue gas etc.) passes into tubulation as thermal source and material indirect heat exchange, has avoided the secondary pollution of material, makes kiln inner exhaust gas treating capacity and CO
2discharge reduces greatly, is beneficial to environmental protection.For example, utilize hot flue gas as thermal source, directly pass in kiln, can bring some nitrogen oxysulfide and CO into
2, be unfavorable for the carrying out of reaction and the purification of product of roasting, and greatly increased vent gas treatment amount, increase processing cost, be unfavorable for environmental protection.
3) heating tubulation is fixing separately, does not rotate with kiln body, and seal member is simple in structure, can not produce heat medium and reveal contaminated environment; When indivedual tubulations break, can in the situation that need not stopping kiln, process in time, improve operation rate, reduce equipment operation energy consumption, there is the outstanding advantages such as energy-conservation, safe.
4) because material has certain height of offering under flight effect, the static tubulation on kiln top only has few directly contacting with material, heating tubulation is only arranged in middle and lower part in kiln, account for 40%～60% of kiln space, in kiln, only arrange the heating tubulation of half left and right, save material, and little on treating capacity impact, greatly reduce equipment investment cost.
The utility model can be widely used in the application such as low temperature pyrogenation and dregs of fat refinement of flyash Extraction of Alumina By The Method of Ammonium Sulfate-gas, coal.This is environmentally friendly, resource-conserving roasting technology project application, in domestic roasting project, can obviously reduce fuel consumption and CO
2discharge, reduces the loss of corollary system, improves the overall efficiency of roasting system.
