Description

Technical Field

[0001] The invention relates to the technical field of ball mills, and in particular to waste gas treatment equipment used in color aluminum production. Background Art

[0002] Painting is an important step in the production process of colored aluminum, which requires painting, drying and curing. A large amount of hot air is required in these steps, and a large amount of waste gas will be generated. Therefore, an incinerator system is often set up to provide a heat source and treat the waste gas by high-temperature oxidation catalysis. The existing incinerator system is slightly insufficient in the efficiency of waste heat recovery, so a new type of waste gas treatment equipment is needed to solve this problem. Summary of the invention

[0003] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a waste gas treatment device for color aluminum production.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a waste gas treatment equipment for color aluminum production, including an incinerator, a burner and an oxidation catalyst mechanism, the incinerator is connected with a heat exchange chamber and a discharge chamber, the heat exchange chamber is located between the discharge chamber and the incinerator, the discharge chamber is provided with a discharge port 1, the heat exchange chamber is provided with a discharge port 2, the incinerator, the heat exchange chamber and the discharge chamber are all penetrated by a plurality of heat conducting pipes, the discharge chamber is separated into an air inlet cavity by a partition plate 1, the discharge chamber is provided with an air inlet connected to the air inlet cavity, the incinerator is separated into an exhaust cavity by a partition plate 2, the exhaust cavity is connected to other spaces in the incinerator through the exhaust port, the exhaust port is located between the burner and the oxidation catalyst mechanism, the two ends of each of the heat conducting pipes are respectively connected to the air inlet cavity and the exhaust cavity, and the heat exchange chamber and the discharge chamber are both provided with guiding mechanisms for guiding gas flow.

[0006] By adopting the above technical scheme, the exhaust gas generated in the steps of painting, curing and drying in the production of colored aluminum can be concentratedly input into the air inlet cavity separated by the partition plate 1 through the air inlet cavity, and enter each heat conduction pipe respectively through the air inlet cavity, pass through the discharge chamber and the heat exchange chamber through the heat conduction pipe, and finally enter the incinerator through the exhaust cavity and the exhaust port separated by the partition plate 2. The exhaust port is between the burner and the oxidation catalyst mechanism, and will be heated by the burner to become high-temperature gas, and then purified by the oxidation catalyst mechanism to remove harmful gases in the gas, and then pass through the heat exchange chamber and the discharge chamber in turn, respectively. The gas is discharged from the discharge port 1 and the discharge port 2. When the purified gas passes through the discharge chamber and the heat exchange chamber in turn, it will continuously pass through the heat pipe up and down under the guidance of the guide mechanism, thereby transferring heat to the exhaust gas in the heat pipe. On the one hand, it reduces its own temperature, and on the other hand, it uses this part of the waste heat to heat the exhaust gas to reduce the energy required to heat the exhaust gas, thereby achieving energy-saving effects. The discharge port 1 and the discharge port 2 can release gases that have been cooled to different degrees, so that they can serve as heat sources in different color aluminum production processes again. The cooperation between the guide mechanism and the heat pipe can greatly improve the thermal conductivity efficiency.

The present invention uses staggered baffles so that the ventilation gaps between adjacent baffles are located at the bottom and top of the discharge chamber or the heat exchange chamber respectively. When the gas passes through, it will first move upward from the bottom to pass through the heat pipe, then pass through the baffle through the ventilation gap at the top, and then move downward to pass through the heat pipe again, and then pass through the baffle through the ventilation gap at the bottom, so as to repeatedly achieve a better heat exchange effect.

[0009] Preferably, each of the baffles is slidably connected to each of the heat conducting pipes, and the discharge chamber is provided with a driving mechanism for driving each of the baffles to move synchronously. In the present invention, since the heat conducting pipes are arranged in a straight line, the baffles are driven by the driving mechanism to slide in a straight line, so that the baffles can slide along the heat conducting pipes, and impurities such as smoke and dust attached to the heat conducting pipes are scraped off by the friction between the baffles and the heat conducting pipes, thereby ensuring the heat conducting efficiency of the heat conducting pipes.

[0014] Preferably, the bottoms of the heat exchange chamber and the discharge chamber are both slidably connected with a chip receiving box. The present invention utilizes the chip receiving box to receive swept impurities, which is convenient for cleaning.

[0015] Preferably, a second brush is provided between each baffle and the discharge chamber and the heat exchange chamber. The present invention utilizes the second brush to sweep impurities dropped on the bottom of the discharge chamber or the heat exchange chamber into the chip receiving box.

[0016] In summary, the beneficial effects of the present invention are:

[0017] 1. When the purified gas passes through the discharge chamber and the heat exchange chamber in turn, it will continuously pass through the heat pipe up and down under the guidance of the guide mechanism, thereby transferring heat to the exhaust gas in the heat pipe, on the one hand lowering its own temperature, and on the other hand using this part of the waste heat to heat the exhaust gas, so as to reduce the energy required to heat the exhaust gas, achieve energy-saving effects, and can well improve the thermal conductivity efficiency.
