Description

Technical Field

[0001] This utility model relates to the field of thermally broken aluminum profiles, specifically a waste gas purification device for the production of thermally broken aluminum profiles. Background Technology

[0002] Thermally broken aluminum profiles are a type of aluminum alloy profile with thermal insulation properties, commonly used in the manufacture of building doors and windows. Their key feature is the addition of a layer of thermal insulation material inside the aluminum alloy profile, forming a "broken bridge" that effectively prevents heat conduction and improves the building's thermal insulation performance. In addition to excellent thermal insulation, thermally broken aluminum profiles also possess superior weather resistance, corrosion resistance, and wind pressure resistance, making them a popular building material on the market today.

[0003] Waste gas is typically generated during the processing and production of thermally broken aluminum profiles, primarily due to reactions such as combustion, melting, and oxidation. This waste gas may contain harmful substances like volatile organic compounds (VOCs), nitrogen oxides, and particulate matter, impacting the environment and human health. For instance, acidic gases such as sulfur dioxide and nitrogen oxides are mainly purified using spraying and adsorption methods, while organic waste gas is often treated by combustion. Waste gas carrying organic pollutants is often treated by photolysis. Traditional industrial waste gas treatment devices primarily use filtration and spraying. However, the varying composition of industrial waste gas can lead to ineffective purification, resulting in air pollution even after purification. Therefore, different purification methods are needed for industrial waste gas with different compositions to improve purification efficiency and effectiveness. Summary of the Invention

[0026] Please see Figure 1-4 The exhaust gas purification device for the production of thermally broken aluminum profiles shown includes a purification box body 1, an exhaust gas detection device 2 at one end of the purification box body 1, an exhaust gas inlet 2a on one side of the exhaust gas detection device 2, a second purification box 3 and a third purification box 4 on one side of the purification box body 1, a first exhaust gas pipe 1a between the exhaust gas detection device 2 and the purification box body 1, a second exhaust gas pipe 3a between the exhaust gas detection device 2 and the second purification box 3, a third exhaust gas pipe 4a between the exhaust gas detection device 2 and the third purification box 4, filter screens 5 at both ends of the purification box body 1, a water curtain plate 6 between the filter screens 5, and a spray nozzle 7 on the top of the purification box body 1.

[0027] The second purification box 3 is a catalytic combustion device used to purify industrial waste gas containing a large amount of organic waste gas.

[0028] The third purification chamber 4 is a photolysis device used to purify waste gas containing a large amount of organic pollutants.

[0029] The main body of the purification chamber 1 uses a conventional spray filtration method to purify most common industrial waste gases, such as acidic gases like sulfur dioxide and nitrogen oxides. A wastewater outlet is located at the bottom of the main body of the purification chamber 1, and wastewater is discharged from the bottom after accumulating to a certain level. The filter screen 5 is honeycomb-shaped, and adsorbent, either activated carbon or molecular sieve, is placed in the mesh of the filter screen 5 to adsorb the waste gas. The filter screens 5 are located at both ends; one end adsorbs the waste gas that just enters the main body of the purification chamber 1, and after being sprayed, it is concentrated at the filter screen 5 at the other end. Bamboo charcoal is added to the filter screen 5 at the other end to adsorb any moisture it may contain. Finally, the waste gas is discharged from the qualified waste gas outlet. The main body of the purification chamber 1, the second purification chamber 3, and the third purification chamber 4 all use air pumps or fans for air extraction and transportation.

[0030] The filter screen 5 and the water curtain plate 6 are provided with a fixed base 8 at the bottom. The filter screen 5 and the water curtain plate 6 are fixed inside the purification box body 1 by the fixed base 8. The fixed base 8 makes the filter screen 5 and the water curtain plate 6 vertically set in the purification box body 1. The water curtain plate 6 is located below the spray nozzle 7. When the spraying starts, the water flow is sprayed on the purification box body 1 through the nozzle. Then the water flow is guided along the water curtain plate 6 to increase the contact area between the exhaust gas and the water flow and improve the spraying neutralization efficiency.

[0031] The main body 1 of the purification box is equipped with a control box 9 on the top. The main body 1 of the purification box is equipped with a clean water pipe. The spray nozzle 7 is connected to the clean water pipe. The control box 9 is where the control system is located. The spray nozzle 7 is supplied with water through the external water pipe.

[0032] The main body of the purification box 1, the first purification box 3 and the second purification box 4 are provided with qualified exhaust gas outlets 10 at the ends away from the exhaust gas detection device 2. The main body of the purification box 1, the second purification box 3 and the third purification box 4 use separate qualified exhaust gas outlets 10 for discharge, or they can be connected into one outlet.

[0033] The specific working principle is as follows: the waste gas generated in the production of thermally broken aluminum profiles is introduced into the waste gas detection device through the waste gas inlet 2a. After being detected by the waste gas detection device, it is classified and then introduced into different purification boxes according to the main components of the waste gas. Different waste gas treatments such as spray filtration, photolysis, and combustion catalysis are carried out to obtain the best waste gas purification efficiency and improve the purification degree. After purification, it is discharged from the qualified waste gas outlet 10.
