Description
Technical field
This utility model relates to Gypsum Fibrosum powder ground production field, particularly relates to a kind of β that is sintered into by desulfurization gypsum powder and builds
The gypsum steam calcining furnace of Gypsum Fibrosum powder.
Background technology
Desulfurated plaster is the by-product of thermal power plant's generating desulfurization, is sintered into that β building gypsum plaster is domestic extensively to be adopted at present
Calcining furnace be rotary kiln and fluidized furnace, rotary kiln and vulcanizing oven all use coal as thermal source, define and strive coal with generating, and
The steam waste heat in power plant often can not get utilizing fully, and utilizing the steam waste heat in power plant to produce β building gypsum plaster is to send out
Electricity an urgent demand industrially.
Summary of the invention
This utility model is to utilize power plant steam to produce the gypsum steam calcining of β building gypsum plaster to calcine desulfurated plaster
Stove, is characterized in that gypsum steam calcining furnace is made up of upper shell, middle shell, lower object three part.
The effect of upper shell is charging and dedusting, and current plaster calcining furnace is Gypsum dust to be united outside calcining furnace
Then one concentrated dust collecting returns again in drying oven, and such process makes Gypsum Fibrosum powder have lost a part of heat energy when returning calcining furnace,
The Gypsum Fibrosum powder that top has been calcined simultaneously is the most easily siphoned away by wind-force, causes the excessive raw gesso of dedusting amount to mix in together,
When outside cleaner returns again to calcining furnace, cause Gypsum Fibrosum powder calcine burning again, and the eddy flow of the interior installation of upper shell
Major part dust collection directly can be continued calcining in gypsum steam calcining furnace by cleaner unit, it is to avoid from outside concentrated dust-removing again
The loss returning calcinating consumption in stove and Gypsum Fibrosum powder calcine, by the phenomenon of burning again, decrease outside dedusting simultaneously
The big pressure of amount.
The effect of middle shell is the drying and calcining dehydration discharge with finished product Gypsum Fibrosum powder of Gypsum Fibrosum powder, and Gypsum Fibrosum powder heats with steam
Pipe fully contacts with steam-heating pipe under the effect of lower house air-flow and generates qualified Gypsum Fibrosum powder.The air inlet of steam-heating pipe
With gas outlet not in same level, there is height fall, in order to the discharge in time of the condensed water that profit steam-heating pipe produces.
Discharging opening is located at the upper end of middle shell, is because gypsum powder heavier, directly sinks to after upper shell material inlet enters
Adding on heat pipe of middle shell bottom.
The effect of lower house is air blast and scarfing cinder.
Upper shell side connects charging aperture, and lower end connects upper shell adpting flange, and upper surface is fixedly connected with pipeline
The cleaning shaft of adpting flange, upper shell is internally installed cyclone dust, and the upper end of cleaner unit connects cleaning shaft, dust removing tube
Road passes upper shell upper plate, and cleaner unit lower end has automatic gravity to lock wind discharge valve, gravity lock wind discharge valve by Flange joint
Gypsum Fibrosum powder can be made to automatically open up discharging after gathering constant weight, and the steam-heating pipe entering lower end continues heating, upper shell another
One lateral surface has circular access hole.
Middle shell side connects has discharging opening, upper end to be fixed with middle shell upper end adpting flange, and lower end is fixed with middle shell
Lower end adpting flange, corresponding with the adpting flange of upper-lower casing respectively, be screwed upper-lower casing adpting flange, by upper,
In, lower house solid be connected together, form gypsum steam calcining furnace overall.
Middle shell steam-heating pipe is distributed in middle shell with S shape stratification, and the import of steam-heated pipe line goes out with corresponding
Mouth keeps drop, is beneficial to naturally discharge from steam-heated pipe line when steam condensation becomes water.Two correspondences in middle shell
Side is fixedly connected with fixing steel plate, and steam-heating pipe is fixed on fixing steel plate by U-shaped fixing card, to reduce and prevention
Steam-heating pipe operationally earthquake motion and deformation.
The air inlet of the steam-heated pipe line in middle shell and gas outlet are each passed through the collection outside housing side panel and housing
Gas tank is fixing to be connected, and air inlet connects air inlet air collector, and gas outlet connects air collector of giving vent to anger.High-temperature steam initially enters air inlet collection
Gas tank, by steam-heating pipe in layering entrance middle shell, from the Gypsum Fibrosum powder of upper shell charging aperture entrance at lower house upwards
Under distinguished and admirable air blast effect, in S curve, motion contacts heated dehydration fully and generates half with the steam-heating pipe in middle shell
Water building gypsum plaster, half water building gypsum plaster of generation is excluded entrance Gypsum Fibrosum storage bin deposit by middle shell discharging opening.Low
Temperature steam enters discharge of giving vent to anger from gas outlet.
Lower house is made up of air compartment and support, and lower house upper end surrounding is fixed with lower house adpting flange, and under middle shell
Corresponding being screwed of end housing adpting flange links together, and air compartment above is fluidisation aerofoil, fluidisation aerofoil be by
The docking of fritter aerofoil is welded, and fritter aerofoil is covered with uniform air holes, and air-flow enters middle shell by fluidisation aerofoil air holes,
Blowing afloat the Gypsum Fibrosum powder in middle shell and the steam-heated pipe line in middle shell is fully contacted, heating Gypsum Fibrosum becomes qualified building
Gypsum Fibrosum powder.Fluidisation aerofoil has the gradient, by four circumference intermediate, inclined, short between surrounding senior middle school, and middle installation connection has electromagnetic lock wind
The scarfing cinder pipeline of discharge gate.During the fluidized drying of Gypsum Fibrosum, heavy debris and do not have pulverized boulder
Material is deposited on the acclive fluidisation aerofoil of tool, and the logistics that fluidisation aerofoil is saved bit by bit is too much, will block the wind on fluidisation aerofoil
Hole, makes wind can not enter middle shell, and what impact produced is normally carried out, and fluidisation aerofoil has the gradient can make debris or boulder stream
Dynamic or be rolled to fluidize scarfing cinder pipe end low in the middle of aerofoil, can be by by periodically opening electromagnetic lock wind discharge gate
Debris Hand scarf i.e. cleans out the fluidisation aerofoil of lower house in normal productive process, keeps fluidisation aerofoil pore ground unimpeded,
The process making land plaster is persistently carried out.
