Abstract
The utility model discloses a cyclical combustion type sleeve lime shaft kiln, comprising a kiln body, a rotating material distributing device arranged at the upper part of the kiln body, and a hydraulic ash discharge device and a storage silo which are arranged at the bottom of the kiln body, wherein the kiln body comprises an inner kiln chamber and an outer kiln chamber which are concentrically arranged, and combustion devices are arranged on the inner kiln chamber and the outer kiln chamber and are arranged in an upper-layer and lower-layer manner. The cyclical combustion type sleeve lime shaft kiln can achieve the goal of calcining high-yield lime by low-heat value fuel and is suitable for a steel enterprise to utilize blast furnace gas to calcine high-yield active lime.
Description
Technical field
The utility model relates to the industrial furnace technical field, specifically a kind of ring burning type sleeve lime shaft kiln.
Background technology
In prior art, when industrial furnace used utilizes the low calorie fuels lime kilning output less and the investment larger.For guaranteeing burning quality, stove output is limited, causes production efficiency low.
The utility model content
The purpose of this utility model is to provide a kind of ring burning type sleeve lime shaft kiln that improves stove output and can utilize low calorie fuels, to solve the low calorie fuels that can't utilize that existing lime calcining stove exists, calcines the problem of large output quickened lime.
The utility model is achieved in that ring burning type sleeve lime shaft kiln, comprise the kiln body, be installed on kiln body top rotary distributing device, be installed on hydraulic pressure ash discharging gear and the storage bin of kiln body bottom, described kiln body comprises interior kiln thorax and the outer kiln thorax of two arranged concentric, on interior kiln thorax and outer kiln thorax, combustion unit all is installed, described combustion unit divides upper and lower two-layer arranging.
In the utility model, form annular calcination space between the interior kiln thorax of two arranged concentric and outer kiln thorax, fill the Wingdale bed of material in this annular calcination space, owing on interior kiln thorax and outer kiln thorax, being evenly equipped with upper and lower two-layer combustion unit simultaneously, make thus the annular Wingdale bed of material be heated in inside and outside both direction, upper and lower two orientation, thereby the heat that the Wingdale bed of material is obtained within the unit time is more simultaneously.In addition, inside and outside both direction and upper and lower two orientation are heated simultaneously, have also improved the calcination uniformity coefficient.Because unit time sodalime stone layer has obtained more and more uniform heat, therefore, the lime calcination quantity completed in the unit time can significantly improve, and then enhances productivity.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the combustion unit schematic diagram of arranging.
Embodiment
Shown in Fig. 1, ring burning type sleeve lime shaft kiln comprises the kiln body, be installed on the rotary distributing device 1 on kiln body top, be installed on hydraulic pressure ash discharging gear 6 and the storage bin 7 of kiln body bottom, described kiln body comprises interior kiln thorax 2 and the outer kiln thorax 3 of two arranged concentric, at interior kiln thorax 2, internal combustion device 5 is installed, outer burning device 4 all is installed on kiln thorax 3 outside, and described combustion unit divides upper and lower two-layer arranging.
In the utility model, the bottom of the described hydraulic pressure ash discharging gear bottom two described kiln bodies is provided with refrigerating unit, and the waste gas withdrawing device is connected on outer kiln thorax.Refrigerating unit, by cooling air distribution piping group, has guaranteed the homogeneity of air-flow and the reasonable layout of pressure; The waste gas withdrawing device distributes for the integral pressure of realizing work kiln thorax, is more conducive to the decomposition of Wingdale.
In the utility model, distribution device adopts the double-layer seal rotary distributing device, can guarantee the pressure-stabilisation in annular burning zone, thereby further guarantee calcination quality and calcination efficiency.
In the utility model, internal combustion device 5, outer burning device 4 all adopt simple and direct structure design, thereby have realized laying in the same cross section of kiln thorax the ideal state (shown in Fig. 2) of dozens of simultaneously, improve thus the balanced intensity that Wingdale is heated.
Described hydraulic pressure ash discharging gear adopts hermetically sealed form, the dust raising phenomenon while having avoided discharging.
Key of the present utility model is to have formed the annular burning space between the interior kiln thorax of two arranged concentric and outer kiln thorax, and the combustion unit that interior kiln thorax and outer kiln thorax are arranged evenly is sent to the annular Wingdale bed of material by heat, has guaranteed thus the yield rate of calcining.And this mode of operation meets the decomposition principle of Wingdale, the high reactivity degree of product and taking full advantage of of heat have been realized.Thus, the utility model can be realized the purpose of low calorie fuels calcining high yield lime, is applicable to iron and steel enterprise and utilizes blast furnace gas to calcine large output quickened lime.
The utility model advantage major embodiment is in the following areas: invest low, output large, the Product Activity degree is high and supporting non-standard equipment is less etc.
