Description
Technical field
The utility model relates to a kind of heat recovery apparatus more particularly to a kind of recuperation of heat dresses applied to aluminum-bar heating furnace
It sets.
Background technique
In the operational process of aluminum-bar heating furnace, need to heat fresh air, after importing equipment use, high-temp waste gas
Device for transferring.The direct emission of high-temp waste gas results in the waste of a large amount of thermal energy, while the heating to fresh air, energy consumption nor
Normal height leads to the whole high production cost of aluminum-bar heating furnace.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, provides a kind of recuperation of heat of aluminum-bar heating furnace
Device reduces the production cost of aluminum-bar heating furnace.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of heat recovery apparatus of aluminum-bar heating furnace, including cabinet, the box house are divided into upper box under by partition
Cabinet, the upper box are connected with fresh air air inlet pipe and fresh air escape pipe, and the lower box is connected with exhaust inlet pipe and exhaust gas
Escape pipe is provided with several heat exchanger tubes in the cabinet, and the heat exchanger tube runs through the partition, and the upper end of the heat exchanger tube is located at
In the upper box, the lower end of the heat exchanger tube is located in the lower box.
Further, the exhaust inlet pipe front end is provided with filter screen.
Further, the exhaust inlet pipe is internally provided with cooling grid, and the cooling grid is hollow type grid,
The cooling grid is connected separately with water inlet pipe and outlet pipe, and the water inlet pipe is connected with cold water storage cistern by intake pump, it is described go out
Water pipe is connected with water storage box by water outlet pump.
A kind of heat recovery apparatus of aluminum-bar heating furnace of the utility model, can recycle the heat of high-temp waste gas and to fresh sky
Gas is preheated, and the production cost of aluminum-bar heating furnace is reduced.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, a kind of heat recovery apparatus of aluminum-bar heating furnace, including cabinet, box house are divided by partition 1 for top box
Body 2 and lower box 3, upper box 2 are connected with fresh air air inlet pipe 4 and fresh air escape pipe 5, and lower box 3 is connected with 6 He of exhaust inlet pipe
Exhaust gas outlet pipe 7 is provided with several heat exchanger tubes 8 in cabinet, and heat exchanger tube 8 runs through partition 1, and the upper end of heat exchanger tube 8 is located at upper box 2
Interior, the lower end of heat exchanger tube 8 is located in lower box 3.
Working principle: high-temp waste gas enters lower box by exhaust inlet pipe, after exchange heat pipe is heated, using exhaust gas
Escape pipe discharge；Meanwhile fresh air is entered by fresh air air inlet pipe, after the heating of heat exchanger tube, is exported by fresh air escape pipe
And it send to heating furnace front end and is used.
6 front end of exhaust inlet pipe is provided with filter screen 9, prevents the waste residue in exhaust gas from entering lower box, if waste residue is attached to
On heat exchanger tube, the heat exchange efficiency of heat exchanger tube can be reduced.
Exhaust inlet pipe 6 is internally provided with cooling grid 10, and cooling grid 10 is hollow type grid, and cooling grid 10 divides
It is not connected with water inlet pipe and outlet pipe, water inlet pipe is connected with cold water storage cistern 12 by intake pump 11, and outlet pipe is connected by water outlet pump 13
It is connected to water storage box 14.The temperature that the exhaust gas that aluminum-bar heating furnace generates generally can bear in 500 degrees centigrades, general heat exchanger tube
Degree is in 300 degrees centigrades, and heat exchanger tube cost resistant to high temperature is very high, therefore adds cooling grid knot in exhaust inlet pipe
Structure carries out cooling pretreatment to exhaust gas, the exhaust gas temperature for entering lower box is reduced to 300 degrees centigrades, passes through intermittence
The opening and closing for controlling intake pump and water outlet pump make the temperature of cooling grid keep substantially constant.
A kind of heat recovery apparatus of aluminum-bar heating furnace of the utility model, can recycle the heat of high-temp waste gas and to fresh sky
Gas is preheated, and the production cost of aluminum-bar heating furnace is reduced.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
