Abstract
The invention relates to the technical field of the roasting of particle materials of lime, calcined dolomite and bauxite and the like, in particular to a shell and tube preheater, comprising a preheater shell, a feed pipe, a warm-air pipe, an exhaust duct, a discharge mechanism, a central hot smoke chamber and a central funnel; the preheater is formed by a plurality of independent single pipe structures in parallel and sealed relatively; the feed pipes of each single pipe structure are respectively arranged at the center position of the top part of the single pipe structure and the top thereof is provided with the independent exhaust duct; the outside of the feed pipe is provided with a rod valve and the inside thereof is provided with a position-controlling special-shaped cover; the discharge mechanism adopts a bottom fault type horizontal material-discharging device; the independent exhaust ducts are arranged at the periphery of a blanking pipe and respectively provided with a regulating valve for gas flow rate and a temperature measuring instrument; the inclined angle of the side wall of the duct is an obtuse angle structure of 95 degrees to 145 degrees with a short edge; and the independent exhaust ducts are respectively connected with a main pipe. The invention has reliable operation, even distribution of got gases, even heating of materials, no dead areas for the move down of the whole materials, smooth operation of materials, even resistance in the exhausting and flowing process without wind inclination and adjustable temperature of flue gases.
Description
Technical field
The present invention relates to lime, forge granule materials roasting technology fields such as white, bauxite, particularly relate to a kind of calandria preheater.
Background technology
Preheater is lime, it is white to forge, (general designation: material) wait granule materials to produce the energy-saving equipment that the calcination rotary kiln system extensively adopts, be that the high-temp waste gas that utilizes the discharge of rotary kiln tail heats lime in advance, forges the equipment of granular material roasting such as white, bauxite to bauxite.High-temp waste gas forms reverse movement with granular material in preheater, 950 ℃～1100 ℃ high-temp waste gas are cooled to 150 ℃～200 ℃, simultaneously most of heat passed to lime, forged granular material such as white, bauxite, it has been preheated to the temperature that needs.Used preheater is the single tube structure at present, the feeding biasing, and local discharge can not need to regulate smoke evacuation with producing.Be heated inhomogeneously so material occurs, flowing resistance is big and inhomogeneous, and local dead band crust, heat exchange state such as can not adjust at problem, have restricted production and quality control.
Summary of the invention
The present invention seeks to be to provide the calandria preheater of energy-conservation, lower resistance that a kind of single tube can independently adjust warm, high usage, high thermal efficiency.
The objective of the invention is to realize by following technical proposals:
Calandria preheater of the present invention, comprise preheater shell, feed pipe, warm-air pipe, exhaust duct, discharging mechanism, the hot smoke-box in center, center go out funnel, it is characterized in that forming side by side the preheater of relative closure by a plurality of independently single tube structures, the feed pipe of each single tube structure all is located at the center of top position of this single tube structure, and the top of each single tube structure is provided with independently exhaust duct.The refractory material protection is all arranged in the housing.
The outside of described feed pipe is provided with excellent valve, and feed pipe is provided with control position abnormity cover in the single tube inside configuration.
Described discharging mechanism adopts the large tracts of land discharge method, adopts the pipe bottom fault type horizontal material-discharging device of adjustable frequency and rise distance.
The independent exhaust duct of described each single tube structure is located at around the feed pipe, and this independent exhaust duct is respectively equipped with gas flow regulating valve and temperature measurer.
The pipe sidewall angle of described single tube structure is the obtuse angle structure with a minor face and 95 °～145 °.
The independent exhaust duct of described each single tube structure all is connected with a house steward.
The independent ∧ tee section warm-air pipe of described each single tube structure communicates with kiln tail gas.
In described preheater shell, be provided with the hot smoke-box in center of preheater.
Be provided with the center funnel at described discharging mechanism downside.
High-temperature portion is equipped with the refractory material protective layer in described preheater.
That the calandria preheater of independently being in charge of combination of the present invention has is reliable, hot gas is evenly distributed, material is heated evenly, material integral body moves down no dead band, the material operation is unobstructed, the even wind partially of resistance in the flue gas process of circulation, the advanced person's that exhaust gas temperature in service is adjustable preheater.
