Description
Technical field
The utility model relates to fluidized bed furnace air inlet field, relates in particular to a kind of fluidized bed furnace blast pipe.
Background technology
The main equipment fluidized bed furnace that utilizes at present sulfate process titanium dioxide discarded object ferrous sulfate relieving haperacidity project, air inlet system is by outside air intakeEquipment is directly blown by blast pipe, and blast pipe is made up of a Steel Tube Special and bracing frame, and this air-intake device causes air compartment to divideWind is inhomogeneous, and wind speed too fast impact in middle part is large. In actual production frequent discovery in service, top blast cap has air leakage phenomena, unionIn in center, cause often blowing wearing boiling bed, dead stove phenomenon frequently occurs, and blast pipe top device is damaged sternlyHeavy. Affect normal production and operating activities simultaneously, make economical impaired serious.
Utility model content
Technical problem to be solved in the utility model is to provide one and makes air compartment blast pipe divide wind uniform novel fluidized bed furnace air intakePipe.
The utility model solves the technical scheme that its technical problem adopts: fluidized bed furnace blast pipe, described airduct comprises high-pressure blastPipe straight length and the high-pressure air hose breeze way of vertically placing, high-pressure air hose breeze way bottom seal, high-pressure air hose straight length is from high pressureAirduct breeze way middle and lower part tangentially enter and with high-pressure air hose breeze way internal communication, also comprise buffer cap, buffer cap is umbrella shape knotStructure, buffer cap is positioned at directly over high-pressure air hose breeze way top exit, and is fixedly connected with high-pressure air hose breeze way upper end, bufferingCap is provided with some air outlets.
Wherein, on the high-pressure air hose breeze way inwall in said apparatus mesohigh airduct straight length exit, be provided with stiffener.
Wherein, high-pressure air hose breeze way is up big and down small funnel-form.
Wherein, high-pressure air hose straight length and high-pressure air hose breeze way are set to removably connect.
The beneficial effects of the utility model are: this apparatus structure is simple, and cost of manufacture is cheap. When use, only the whole series need be seethed with excitementStove blast pipe is fixed in fluidized bed furnace air compartment, high-pressure air hose straight length is effectively connected with external air source pipe simultaneously, opens outside and sendWind apparatus can use. The high pressure draught that outside air-supply arrangement produces tangentially enters high-pressure air hose buffering by high-pressure air hose straight lengthSection, forms Scroll-tupe high pressure draught and spirals and rise to exit, high-pressure air hose breeze way upper end, inside high pressure draught and buffer capContact, high pressure draught changes flow direction thereupon, and high pressure draught overflows from the air outlet being arranged on buffer cap body, makes heightPressure gas stream scatter, and evenly rises to superstructure. This structure greatly reduces the impact of high pressure draught to superstructure, makesObtain whole device and operate steadily, extended the service life of equipment.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure, be labeled as: the 1st, high-pressure air hose straight length, the 2nd, stiffener, the 3rd, high-pressure air hose breeze way, the 4th, air outlet, 5It is buffer cap.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, fluidized bed furnace blast pipe, is characterized in that: described airduct comprises high-pressure air hose straight length 1 and vertically placesHigh-pressure air hose breeze way 3, high-pressure air hose breeze way 3 bottom seal, high-pressure air hose straight length 1 is from high-pressure air hose breeze way 3Middle and lower part tangentially enter and with high-pressure air hose breeze way 3 internal communication, also comprise buffer cap 5, buffer cap 5 is beveled structure,Buffer cap 5 is positioned at directly over high-pressure air hose breeze way 3 top exits, and is fixedly connected with high-pressure air hose breeze way 3 upper ends, slowRush cap 5 and be provided with some air outlets 4. Those skilled in the art can understand, and the utility model is preferred buffer cap 5For umbrella-shaped structure, the effect of buffer cap 5 is change pipeline inner high voltage airflow direction and reduce the impact of high pressure draught to top member,Also can be pyramidal structure, buffer cap 5 bottom transverse areas of section should be greater than high-pressure air hose breeze way 3 top cross-sectional areas, willHigh-pressure air hose breeze way 3 covers. Above-mentioned high-pressure air hose straight length 1 axis and the high-pressure air hose breeze way 3 of tangentially also should making simultaneouslyAxis is vertical, and high-pressure air hose straight length 1 internal diameter should be less than high-pressure air hose breeze way 3 internal diameters simultaneously. When use, need be by the whole seriesBlast pipe is fixed in fluidized bed furnace air compartment, and high-pressure air hose straight length 1 is effectively connected with external air source pipe, opens outside air-supply dressPut and can use. The high pressure draught that air-supply arrangement produces tangentially enters high-pressure air hose breeze way 3 by high-pressure air hose straight length 1,Formation Scroll-tupe high pressure draught spirals and rises to exit, upper end, high pressure draught and the interior side contacts of buffer cap 5, high pressure draught thereuponChange flow direction, high pressure draught overflows from air outlet 4 gaps that are arranged on buffer cap 5, and high pressure draught is scatter,Evenly rise to superstructure. This structure greatly reduces the impact of high pressure draught to superstructure, makes whole device operationSteadily, extended the service life of equipment.
Preferably, on high-pressure air hose breeze way 3 inwalls in said apparatus mesohigh airduct straight length 1 exit, be provided with stiffener2. Those skilled in the art can understand, and high pressure draught with pressure in high-pressure air hose straight length 1 pipe, cushions from high-pressure air hoseSection 3 tangentially enters, and high-pressure air hose breeze way 3 inwalls are existed and washed away, and the high-pressure air hose in high-pressure air hose straight length 1 exit is slowCan there is cavitation in punching section 3 inwalls, thereby damage this place's interior wall construction. The utility model is considered this latent defect just, thereforeThis place's inwall is provided with stiffener 2 and reinforces, and this stiffener 2 thickens these place's high-pressure air hose breeze way 3 inwalls, therebyCan effectively alleviate cavitation phenomenons, high-pressure air hose breeze way 3 is further protected, extend its service life, thereby reduce dimensionAccomplish this, increase economic efficiency.
Preferably, said apparatus mesohigh airduct breeze way 3 upper-end inner diameter are greater than bottom internal diameter. Those skilled in the art can manageSeparate, high-pressure air hose breeze way 3 is similar inverted round stage shape structure, and high pressure draught enters high-pressure air hose breeze way 3 from bottom,Bottom size is little, makes high pressure draught flow velocity very fast, tangentially enters and makes high pressure draught be spiral vortex type rising, upper dimension settingLarger, flow velocity is more and more slower from bottom to up in increasing high-pressure air hose breeze way 3 cross-sectional areas, to make high pressure draught, makesMust be uniformly dispersed by pipe inner high voltage air-flow, also reduced to a certain extent the impact of high pressure draught to other equipment, make whole simultaneouslyIndividual device operates steadily. Reduce device damage, saved maintenance cost, improved benefit.
Preferably, said apparatus mesohigh airduct straight length 1 is set to removably connect with high-pressure air hose breeze way 3. This areaTechnical staff can understand, and high-pressure air hose straight length 1 is set to removably connect with high-pressure air hose breeze way 3, has manyAdvantage, for example, in installation process, removably connect and be convenient to segmentation installation adjustment, easier fixed component position. Simultaneously when needingWhile replacing, package unit need not be changed, only needing to change damaged member can normally use, and has saved maintenance time,Reduce cost.
