Abstract
The utility model relates to a double-layer channel interactive calcination and preheating lime kiln which structurally comprises two work kiln chambers arranged in parallel, and a double-layer connecting channel is connected between the two work kiln chambers. According to the double-layer channel interactive calcination and preheating lime kiln, the straight-through type double-layer connecting channel is arranged between the work kiln chambers arranged in parallel, periodical alternation of kiln chamber calcination and kiln chamber preheating can be achieved in the two work kiln chambers, and therefore smooth implementation of calcination parallel flow and preheating integral countercurrent is guaranteed. The working mode is suitable for the limestone decomposition principle, and full utilization of high activity and preheat of products is achieved. According to the design of the double-layer connecting channel, physical isolation of lime cooling air and high-temperature air currents is guaranteed in cooling zones of the work kiln chambers, stable pressure of kiln chamber work areas is achieved, and air flows are distributed reasonably.
Description
Technical field
The utility model relates to a kind of limestone kiln, the specifically mutual calcining of a kind of double-deck passage and preheating type limestone kiln.
Background technology
Traditional lime shaft kiln mostly is whole cocurrent flow type or whole reverse-flow calcining manners, and this mode of operation does not meet the decomposition principle of Wingdale, cause product of low quality, heat utilization efficiency is low and thermosteresis is large.Traditional double-hearth lime kiln, its connecting passage is looped around the circumferential perimeter of burner hearth, easily causes air turbulence, is difficult for calcining control.
The utility model content
The purpose of this utility model just provides the mutual calcining of a kind of double-deck passage and preheating type limestone kiln, the quality that existing limestone kiln exists is low to solve, heat waste greatly and calcine uppity problem.
The utility model is achieved in that the mutual calcining of a kind of double-deck passage and preheating type limestone kiln, comprises two juxtaposed work kiln thoraxes, is connected to double-deck connecting passage between two described work kiln thoraxes.
Top at two described work kiln thoraxes is respectively arranged with automatic material receiving device, in two described work kiln thoraxes, be respectively arranged with combustion unit, bottom at two described work kiln thoraxes is respectively arranged with automatic ash discharge, the bottom of the described automatic ash discharge bottom two described work kiln thoraxes is respectively arranged with refrigerating unit, and the waste gas withdrawing device is connected on one of them described work kiln thorax.
Automatically material receiving device is used for feeding in raw material in the non-working time, can guarantee the pressure-stabilisation of work band; The design of roasting assembly has overcome the homogeneity of heat distribution, has avoided simultaneously taking the air-cooled measure of burner, and working cost is reduced, and function easily realizes; Automatic ash discharge is hermetically sealed carrying out, the dust raising phenomenon when having avoided discharging; Refrigerating unit has guaranteed the homogeneity of air-flow and the reasonable layout of pressure by the cooling air divider; The integral pressure that the waste gas withdrawing device is used for realization work kiln thorax distributes, and is beneficial to the decomposition of Wingdale.
Key of the present utility model is the double-deck connecting passage that is provided with through type between two juxtaposed work kiln thoraxes, because the setting of this bilayer connecting passage, can in two work kiln thoraxes, realize regularly hocketing of the calcining of kiln thorax and kiln thorax preheating work, guarantee thus the smooth enforcement of the whole adverse current of calcining and stream and preheating.And this mode of operation meets the decomposition principle of Wingdale, has realized the high reactivity degree of product and taking full advantage of of heat.The design of double-deck connecting passage has guaranteed the physical isolation of lime cooling air and high temperature gas flow in the cooling zone of work kiln thorax, realized the pressure-stabilisation of kiln thorax workspace, air-flow is distributed more reasonable.The reasonable principle of work of calcining and adverse current preheating can be realized and flow to the utility model, guaranteed the high quality of product and the high utilization rate of heat.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of double-deck connecting passage.
Among the figure: 1, work kiln thorax, 2, double-deck connecting passage, 3, automatic material receiving device, 4, automatic ash discharge, 5, combustion unit, 6, refrigerating unit, 7, the waste gas withdrawing device.
Embodiment
As shown in Figure 1, work body of the present utility model is two juxtaposed work kiln thoraxes 1, and the position, middle and lower part between two work kiln thoraxes 1 is connected to straight-through double-deck connecting passage 2.Be respectively arranged with automatic material receiving device 3 at the top of two work kiln thoraxes 1, in two work kiln thoraxes 1, be respectively arranged with combustion unit 5, bottom at two work kiln thoraxes 1 is respectively arranged with automatic ash discharge 4, bottom at the automatic ash discharge 4 of two work kiln thorax 1 bottoms is respectively arranged with refrigerating unit 6, and waste gas withdrawing device 7 is connected on one of them work kiln thorax.
The reception work of raw material is finished by automatic material receiving device 3; The discharging of lime is finished by automatic ash discharge 4; Lime calcining work is finished by combustion unit 5; Combustion unit 5 comprises that part of fuel pressure conveyer device, Fuel lance, combustion air pressurizing device and e Foerderanlage.The lime cooling work is to be finished by refrigerating unit 6; The discharge of the waste gas in the work kiln thorax 1 and the formation of kiln gun pressure power system are to be finished by waste gas withdrawing device 7.
This Novel lime kiln is divided into two work kiln thoraxes 1, by up and down two mutual UNICOMs of passage (Fig. 2) of double-deck connecting passage 2.Calcine at a work kiln thorax in (becoming the calcining thorax), another work kiln thorax carries out preheating (becoming the calcining thorax) to Wingdale.The high-temperature gas of calcining thorax enters the preheating thorax by communicating passage, has realized taking full advantage of of heat energy; Finish and through discharging with again after the charging in the calcining of calcining thorax, the work of two kiln thoraxes exchange, namely the preheating thorax begins to calcine, and becomes new calcining thorax; Calcining thorax originally then becomes the preheating thorax, and the Wingdale raw material of newly packing into is carried out preheating.
Claims (2)
1. mutual the calcining and the preheating type limestone kiln of double-deck passage comprises two juxtaposed work kiln thoraxes, it is characterized in that, is connected to double-deck connecting passage between two described work kiln thoraxes.
2. limestone kiln according to claim 1, it is characterized in that, top at two described work kiln thoraxes is respectively arranged with automatic material receiving device, in two described work kiln thoraxes, be respectively arranged with combustion unit, bottom at two described work kiln thoraxes is respectively arranged with automatic ash discharge, the bottom of the described automatic ash discharge bottom two described work kiln thoraxes is respectively arranged with refrigerating unit, and the waste gas withdrawing device is connected on one of them described work kiln thorax.
