Description
Technical field
The utility model relates to a kind of kiln of lime kilning, and the generation chamber of environmental protection and energy saving combustion gas is specifically burnt the carbon shaft furnace.
Background technology
The kiln of existing calcined lime mostly is the multifuel combustion kiln that fuel and building stones are positioned at same combustion chamber, and it is insufficient to burn, and energy-output ratio is big, atmospheric pollution is serious, and building stones are heated inhomogeneous, and impurity is many in the lime that burns till, poor product quality.
Summary of the invention
The purpose of this utility model provides the environmental protection and energy saving combustion gas generation chamber of a kind of energy-saving and environmental protection, good product quality and burns the carbon shaft furnace.
The utility model is that the technical scheme that adopted of technical solution problem is as follows:
Environmental protection and energy saving combustion gas generation chamber described in the utility model is burnt the carbon shaft furnace and is comprised shaft furnace cylindrical shell and gas generating chamber, it is characterized in that: the sidewall of described shaft furnace cylindrical shell is provided with the combustion chamber, the outer end of described combustion chamber is communicated with the gas exit of gas generating chamber, the inner of combustion chamber is fixedly connected on the sidewall of shaft furnace cylindrical shell, and the sidewall of shaft furnace cylindrical shell and junction, combustion chamber is provided with the hollow hole that runs through sidewall.
The cross section of described shaft furnace cylindrical shell is oval, and the combustion chamber is arranged on the described oval-shaped major axis cambered surface.
Be fitted with the hot blast recovery tube on the sidewall of described shaft furnace cylindrical shell, the inner sidewall that described hot blast recovery tube is arranged in the shaft furnace cylinder lumen is provided with a plurality of through holes, and the outer end that the hot blast recovery tube is positioned at shaft furnace cylindrical shell outside is connected on the combustion chamber burner of gas generating chamber.
Owing to adopted said structure, this lime shaft kiln has following advantage: the complicated technology that 1, has reduced the multifuel combustion kiln; 2, reduce building stones, fuel consumption, reduced investment; 3, because of being that adverse current feeds intake, building stones are fully preheating in oval cylindrical shell, and heat can make full use of, and has reached energy-conservation effect, about one ton of lime consumption of every burning standard coal 110kg, economizes on coal 20%-30% than multifuel combustion kiln; 4, it is indoor that the fire of gas generating chamber's internal combustion, coal gas are directly delivered to the kiln built-in combustion, carries out the secondary high-temp combustion, sufficient combustion, no black smoke is discharged, and gas generating chamber is low temperature, low blast burning, and the discharge flue dust is few, the waste gas that lime shaft kiln is discharged is through water film dedusting, breaking away from can be up to standard; 5, this lime shaft kiln thermal zone reasonable material of heat preservation and insulation that used of shaft furnace particularly, heat insulation, heat insulation effect is remarkable, the general multifuel combustion kiln of this ratio is economized on coal more than 10%; 6, with this shaft furnace calcined lime, the product activity degree〉360ml, burning, living burning rate＜3%, lime does not have impurity such as cinder, lime is very clean, the working power of this kiln is little, economize on electricity more than 25% than general shaft furnace, coal burns through first and second in burning, it is very abundant to burn, and because of primary combustion is low temperature, low blast burning, the flue dust of getting rid of in coal gas, the fire seldom, the waste gas of discharging in the kiln is sent into Production of Light Calcium Carbonate line carbonic acid gas carbonization chamber after through water film dedusting, desulfurization, can exhaust gas utilization.

Embodiment
As shown in Figure 1, environmental protection and energy saving combustion gas generation chamber described in the utility model is burnt the carbon shaft furnace, comprise shaft furnace cylindrical shell 1 and gas generating chamber 2, the upper end of shaft furnace cylindrical shell 1 is provided with opening for feed and flue 7, these flue 7 one ends are communicated with the inner chamber of shaft furnace cylindrical shell 1, the other end connects induced draft fan and is connected to desulfurating dust-removing equipment, discharges later on through desulfurization and dedusting.
As shown in Figure 3, the sidewall of described shaft furnace cylindrical shell 1 is provided with combustion chamber 3, and the cross section of this shaft furnace cylindrical shell 1 is oval, and combustion chamber 3 is arranged on the described oval-shaped major axis cambered surface, two groups of combustion chambers 3 relatively are arranged on the both sides of shaft furnace cylindrical shell 1, and flame distribution is even.The outer end of described combustion chamber 3 is communicated with the gas exit of gas generating chamber 2, and the inner of combustion chamber 3 is fixedly connected on the sidewall of shaft furnace cylindrical shell 1, and shaft furnace cylindrical shell 1 is provided with the hollow hole 4 that runs through sidewall with the sidewall of 3 junctions, combustion chamber.As shown in Figure 4, described hollow hole 4 can be the tracery wall that adopts refractory brick to be built into.Certainly, in order to improve heat insulation effect, can also on the sidewall of combustion chamber 3, thermal insulation layer be set.
Be fitted with hot blast recovery tube 5 on the sidewall of described shaft furnace cylindrical shell 1, the inner sidewall that described hot blast recovery tube 5 is arranged in shaft furnace cylindrical shell 1 inner chamber is provided with a plurality of through holes, and the outer end that hot blast recovery tube 5 is positioned at shaft furnace cylindrical shell 1 outside is connected on the combustion chamber burner 6 of gas generating chamber 2.Certainly, in order to improve the effect that hot blast reclaims, can also on hot blast recovery tube 5, induced draft fan be set.
During use, combustion gas generation chamber burning coal produces coal gas, air-flow is direction shown in the arrow in Fig. 1, gas exit by gas generating chamber 2 enters combustion chamber 3, enter in the inner chamber of shaft furnace cylindrical shell 1 by hollow hole 4 again, burn in the inner chamber of combustion chamber 3 and shaft furnace cylindrical shell 1, temperature of combustion can reach 1100 ℃-1400 ℃.The opening for feed input of building stones by shaft furnace cylindrical shell 1 upper end, the high temperature of gas-fired burns the building stones heating ripe, and the required oxygen that burn is from the blast inlet of shaft furnace cylindrical shell 1 bottom, and the waste gas that burning produces is by flue 7 discharges; Meanwhile, hot blast recovery tube 5 is collected the combustion chamber burner 6 that the not clean-burning hot gas of part is delivered to gas generating chamber 2, enters gas generating chamber 2 and produces secondary combustion.Coal burns through first and second in burning, it is very abundant to burn, and because of primary combustion is low temperature, low blast burning, the flue dust of getting rid of in coal gas, the fire seldom, the waste gas of discharging in the kiln is sent into Production of Light Calcium Carbonate line carbonic acid gas carbonization chamber, exhaust gas utilization after through water film dedusting, desulfurization.
