Abstract
The utility model relates to sleeve kiln lime cooling equipment. The lime cooling equipment comprises a ventilation pipe and a distributor, wherein a flowmeter and an adjusting valve are arranged on the ventilation pipe; the ventilation pipe is inserted into a lime storage bin of the lower part of a kiln body from the lateral wall of the kiln body, and connected with the distributor; the distributor is a honeycomb duct or an annular distribution tube; the honeycomb duct is of a straight pipe structure with upper and lower openings, and positioned in the center of the kiln body; the annular distribution tube is concentrically arranged with the kiln body; air outlets are formed in upper and lower sides of the annular distribution tube, and the number and sizes of the air outlets are determined according to the size of the sleeve kiln and the process requirement. According to the sleeve kiln lime cooling equipment, cooling air is uniformly distributed on the whole section of the cooling zone of the lime kiln by opening the outlet of the ventilation pipe of the cooling zone on the distributor, so that the cooling air is distributed uniformly, air is prevented from being segregated or short circuited, the lime is sufficiently cooled, the cooling speed is high, the lime discharge temperature is stable, and the activity of lime can be improved.
Description
Technical field
The utility model belongs to building materials, chemical production equipment technical field, relates to a kind of lime cooling apparatus, is specifically related to the lime cooling apparatus that a kind of sleeve kiln is used.
Background technology
Telescopic shaft furnace has another name called ring kiln, originates from Teller company of the graceful department of German Beckenbach Weir, and cover for seat cartridge type shaft furnace comes into operation surplus in the of existing 300 in the world.Practice shows that telescopic shaft furnace equipment is simple, and Operation and maintenance are convenient, and Working environment is better, and calcination product is superior in quality, is a kind of very promising novel stove.
Be divided into preheating zone, calcining zone and cooling zone in the kiln body of limestone kiln.The preheating zone utilizes the high temperature air preheating limestone material after the calcining; Calcining zone utilization burning liberated heat is calcined Wingdale, makes decomposition of limestone become lime and carbonic acid gas; Lime after cooling zone utilizes freezing air to calcining cools off.Telescopic limestone kiln is a negative-pressure operation, and cooling air cools off through the cooling zone that vent-pipe gets into the kiln body automatically.The cooling apparatus of prior art is that vent-pipe gets in the kiln body from the kiln bottom, and cooling air directly gets into cooling zone from the vent-pipe outlet lime is cooled off.The deficiency that this type of cooling exists is the easy segregation of cooling air, walks short circuit, and the cooling air skewness influences the cooling performance of lime and the quality of lime product.
Summary of the invention
For remedying the deficiency of above-mentioned prior art, the utility model provides a kind of sleeve kiln lime cooling apparatus, and the cooling zone cooling air is evenly distributed, and the lime cooling is rapid, ash discharge temperature-stable, the quality of raising lime product.
The utility model sleeve kiln lime cooling apparatus comprises vent-pipe, and under meter and variable valve are housed on the vent-pipe.The sleeve kiln is provided with preheating zone, calcining zone and cooling zone.Cooling apparatus also is provided with sparger, and vent-pipe inserts the lime storage warehouse of kiln body bottom from the sidewall of kiln body, and vent-pipe is connected with sparger.Sparger is thrust-augmenting nozzle or annular spread pipe.Thrust-augmenting nozzle is upper and lower open straight tube structure, and thrust-augmenting nozzle is positioned at the center of kiln body.Annular spread pipe and kiln body arranged concentric, the upper and lower both sides of annular spread pipe are provided with air outlet opening, and the quantity of air outlet opening and size are confirmed according to sleeve kiln size and processing requirement.
The air outlet opening of the upper and lower both sides of annular spread pipe is preferably 4～20, and the aperture of air outlet opening is 10～100mm.The material of thrust-augmenting nozzle and annular spread pipe is carbon steel or heat-resisting steel or stainless steel.Vent-pipe is welding with sparger or is threaded.
The utility model is installed sparger through the vent-pipe outlet at cooling zone, makes cooling air be uniformly distributed in the whole cross section of lime cooling zone, and cooling air is evenly distributed; Avoid windage yaw to analyse or walk short circuit; Lime is fully cooled off, and speed of cooling is fast, the ash discharge temperature-stable, helps improving activity of lime.The utility model is simple in structure, and is easy for installation, and cost is low, is applicable to sleeve limestone kiln cool lime, also can be used for the device chilled product of other negative-pressure operation.
