Description

Baked brick furnace fast cooling and residual heat using device

Technical field

The utility model relates to baked brick furnace.

Background technology

The formula sintering brickkiln that links up is a microscler kiln body, enters the kiln car of the full green compact of row from an end of kiln body, and ejects from the other end of the kiln body kiln car that sintering is intact.Present coal gangue perforated brick just adopts this continous way mode of production.Coal gangue perforated brick, be to utilize the carbon containing of gangue own to carry out spontaneous combustion to bake bricks, in calcining kiln, enter cooling section through crystal formation conversion after preheating, high-temperature roasting, the insulation, this moment, brick body temperature degree was still about 800 ℃, this part heat can only be dispersed in the atmosphere by Yao Ding, Yao Qiang, kiln car and flue chimney combustion air by the mode of heat radiation, convection current, the mode of this natural heat dissipation, the one, radiating rate is slow, influence the ordinary production operation, and the finished bricks temperature behind the kiln discharge influences the entrucking outward transport more than 100 ℃; The 2nd, a large amount of heat energy are dispersed in the air, cause great waste.Calcining kiln production is successional, and the environment temperature in each position of cooling section also is relatively stable, the clean no flue dust of the thermal source of this moment, and this just provides stable thermal source for UTILIZATION OF VESIDUAL HEAT IN.

Present UTILIZATION OF VESIDUAL HEAT IN mode is that hot blast directly is sent to the hothouse dry brick with pipeline.But upset wind path in actual applications, influence is produced, and the heat energy loss is big, is difficult to reach the expection thermal utilization effect.

The utility model content

The purpose of this utility model is to lower the temperature slowly and the problem that makes full use of of waste heat for solving baked brick furnace, proposes the device of a kind of fast cooling and UTILIZATION OF VESIDUAL HEAT IN.

For achieving the above object, the technical solution of the utility model is: the cooling section top in stove vertically is arranged with some endothermic tubes to both sides respectively, the end of all endothermic tubes in kiln and the perforation water pipe connection of closed at both ends, the other end of all endothermic tubes are exposed the back respectively and are connected with the perforation steam pipe of closed at both ends from kiln body both sides; A drum is settled at top at stove, is connected with feed pipe and steam pipeline on the drum; The bottom of drum is connected with downcomer, and the perforation water pipe that downcomer passes in Yao Ding and the kiln is connected; The both sides of drum are connected with upper gas tube respectively, and the upper gas tube of both sides is connected with the perforation steam pipe of both sides respectively.

Operation principle of the present utility model is: the water that feed pipe comes enters and enters downcomer behind the drum and be distributed in the endothermic tube by connecting water pipe, endothermic tube evaporates the water after absorbing high temperature, steam concentrates the back to enter drum from upper gas tube by connecting steam pipe, and the steam in the drum is by the outside delivering vapor of conveyance conduit.

Good effect of the present utility model is: because the heat of stove cooling section absorbed in a large number, thus faster than natural cooling rate, the production process time is shortened, the kiln discharge finished bricks is reduced to tens degree, and kiln discharge can be sold outward transport, does not take the heat radiation place; Because surplus temperature exchanges by carbonated drink in the kiln, become steam thermal energy, be fully used, steam can be carried at a distance, be used for Winter heat supply heating and other factories and use, a common stove can provide the thermal source of more than 2,000 ton of standard coal (7000 kilocalorie/kilogram) every year.

The specific embodiment

With reference to Fig. 1 Fig. 2 technical solutions of the utility model are further specified.Shown in Figure 2 as Fig. 1, method of the present utility model is that the cooling section top in stove 1 is some endothermic tubes 2 on the vertical arranged in both sides; Endothermic tube 2 adopts the above seamless steel pipe of φ 20cm, endothermic tube 2 is arranged close to increase endotherm area as far as possible, all endothermic tubes 2 are connected with the perforation water pipe 9 of a closed at both ends in kiln, and all endothermic tubes 2 expose from the both sides of kiln, connect with the perforation steam pipe 3 of a closed at both ends respectively after exposing; Settle a drum 6 at the top of stove 1, be connected with feed pipe 7 on the bubble bag 6, feed pipe 7 provides high-pressure water by high-pressure hydraulic pump; The bottom of drum 6 is connected with downcomer 4, and the perforation water pipe 9 that downcomer 4 passes in Yao Ding and the kiln is connected; The both sides, top of drum 6 are connected with upper gas tube 5, and upper gas tube 5 is connected with the perforation steam pipe 3 of both sides respectively outside kiln; The top of drum 6 is provided with steam conveying pipe 8, and steam is by conveyance conduit 8 outside delivering vapors.

Operation principle of the present utility model is: the water of feed pipe 7 enters and enters downcomer 4 behind the drum 6 and be distributed in the endothermic tube 2 by connecting water pipe 9, after absorbing high temperature, endothermic tube 2 evaporates the water, steam concentrates the back to enter drum 6 from upper gas tube 5 by connecting steam pipe 3, and the steam in the drum 6 is by conveyance conduit 8 outside delivering vapors.
