Abstract
The invention relates to the technical field of calcination of materials of lime, calcined dolomite and bauxite and the like, in particular to a multipoint cooling heat exchanger, comprising an exchanger shell, a fan and an air duct; the bottom of the exchanger shell is provided with a ring-shaped main pipe connected with the air duct; a plurality of air outlets are arranged at the periphery and the center of the ring-shaped main pipe; the upper parts of the air outlets are provided with a fork flow-guiding device; the number of the air outlets is 3 to 8, namely 2 to 6 air outlets are uniformly arranged at the periphery of the ring-shaped main pipe and 1 to 3 air outlets are respectively arranged at the center of the ring-shaped main pipe; and the number of the air outlets is 5, namely four air outlets are uniformly arranged at the periphery of the ring-shaped main pipe and one air outlet is arranged at the center of the ring-shaped main pipe. The over flow air on the section, which is vertical to the conveying direction of materials, and of the space filled with materials of the whole heat exchanger, is distributed evenly and the average height of material columns is relatively reduced. The air and the high-temperature materials realize uniform heat exchanging, thus improving the heat exchanging efficiency and achieving the object of saving energy and reducing consumption.
Description
Technical field
The present invention relates to lime, forge material calcining technical fields such as white, bauxite, particularly relate to a kind of multi-point cooling heat exchanger.
Background technology
Heat exchanger is lime, it is white to forge, bauxite (general designation: material) produce one of calcination rotary kiln system host equipment.Be the heat that utilizes the finished product of roasting success to take away, the auxiliary air heating that will use for burning and the equipment that high-temperature material is cooled off.The temperature of high-temperature material can be up to 1100 ℃, directly contact and relative motion with the cold air of introducing during by heat exchanger, and the cold air heat absorption heats up and reaches that to incorporate kiln into more than 500 ℃ combustion-supporting, and the material cooling effect that is subjected to air is simultaneously reduced to below 100 ℃ by 1100 ℃.The main points of this process: the one, it is high that heat exchange efficiency is wanted, and the 2nd, flowing resistance is low.
The single-point cooling heat exchanger because air-supply point converges, cause from air-supply point far and near windage and air quantity difference very big, thereby make material heat exchange inequality and flowing resistance size uneven, influence output and quality and UTILIZATION OF VESIDUAL HEAT IN.
Summary of the invention
The present invention seeks to be to provide the heat transmission equipment of a kind of high heat exchanger effectiveness, low flowing resistance, multi-point cooling heat exchanger.
The objective of the invention is to realize by following technical proposals:
Multi-point cooling heat exchanger of the present invention, comprise outer cover of heat exchanger, blower fan, the air duct that passes outer cover of heat exchanger that is connected of blower fan therewith, it is characterized in that being provided with a belt total pipeline that is connected with described air duct in the bottom of described outer cover of heat exchanger, around this belt total pipeline, reach a center arrangement 3-8 exhaust vent, above these exhaust vents, be provided with the fork-shaped guiding device.
Around described belt total pipeline, 2-6 exhaust vent be set evenly, 1-3 exhaust vent be set in the central authorities of belt total pipeline.
Described exhaust vent is 5, and four exhaust vents promptly evenly are set around the total pipeline that goes in ring, and in the central authorities of the total pipeline that goes in ring an exhaust vent is set.
Operation principle of the present invention is: Cryogenic air is pressurizeed the back by the belt pipeline in the pipeline introducing heat exchanger by blower fan, around the belt pipeline and a plurality of exhaust vents of center arrangement, make whole heat exchanger to be full of material space overcurrent air on the section vertical with the material traffic direction be uniform.Ventilation is uniformly on the whole section, and average stock column height reduces relatively.Air and high-temperature material have been accomplished even heat exchange, have improved heat exchange efficiency.Under the condition that equally material is cooled to below 100 ℃, cooling air heat absorption heats up and can be thus lifted to 700 ℃ by 500 ℃, has reached energy saving purposes.
Description of drawings
Fig. 1 is the structural representation of multi-point cooling heat exchanger of the present invention.
The specific embodiment
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, multi-point cooling heat exchanger of the present invention, comprise outer cover of heat exchanger 1, blower fan 3, the air duct that passes outer cover of heat exchanger 14 that is connected of blower fan 3 therewith, it is characterized in that being provided with a belt total pipeline 5 that is connected with described air duct 4 in the bottom of described outer cover of heat exchanger 1, around this belt total pipeline 5, reach a center arrangement 3-8 exhaust vent 6, above these exhaust vents 6, be provided with fork-shaped guiding device 2.
Around described belt total pipeline, 2-6 exhaust vent be set evenly, 1-3 exhaust vent be set in the central authorities of belt total pipeline 5.
Described exhaust vent 6 is 5, and four exhaust vents promptly evenly are set around the total pipeline 5 that goes in ring, and in the central authorities of the total pipeline that goes in ring an exhaust vent is set.
Operation principle of the present invention is: Cryogenic air is pressurizeed the back by the belt pipeline in the pipeline introducing heat exchanger by blower fan, around the belt pipeline and a plurality of exhaust vents of center arrangement, make whole heat exchanger to be full of material space overcurrent air on the section vertical with the material traffic direction be uniform.Ventilation is uniformly on the whole section, and average stock column height reduces relatively.Air and high-temperature material have been accomplished even heat exchange, have improved heat exchange efficiency.Under the condition that equally material is cooled to below 100 ℃, the heat absorption of cooling air heats up and can be thus lifted to 700 ℃ by 500 ℃.Reached energy saving purposes.
