Description

Technical Field

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously pollutes the environment and affects human health, and has a serious impact on environmental engineering. Sulfur dioxide is a common toxic waste gas. In the process of purifying it, limestone emulsion is often used to spray sulfur dioxide gas, so that it reacts with calcium hydroxide in the limestone emulsion to form gypsum and water. However, in actual use, because sulfur dioxide is a gas, it floats in various positions in the reaction box, resulting in the limestone emulsion being unable to quickly contact and react with sulfur dioxide gas during spraying, resulting in low waste gas treatment efficiency. Therefore, a waste gas treatment device for environmental engineering is needed.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] It should be noted that the specific installation method of the motor 7 and the circuit connection method and control method in the present invention are all conventional designs and are conventional design means of designers.

By installing the motor 7, the reaction mechanism 6 can be powered. By installing the discharge pipe 4, which itself has a valve, the discharge of the reaction product can be controlled.

[0029] In order to achieve the purpose of filtering particulate matter in the exhaust gas, such as Figure 2 and Figure 3As shown, the filtering mechanism 2 includes a shell 21, a rotating fan 23 is rotatably connected to the rear right side of the inner cavity of the shell 21, a transfer wheel 24 is fixedly connected to the middle of the upper end of the rotating fan 23, a belt 25 is wrapped around the inner cavity of the transfer wheel 24, a dust group 26 is wrapped around the side of the inner cavity of the belt 25 away from the transfer wheel 24, a filter plate 27 is fixedly connected to the left part of the dust removal group 26, the outer surface of the filter plate 27 is fixedly connected to the left part of the inner cavity of the shell 21, a dust box 28 is fixedly connected to the middle part of the lower end of the shell 21, the middle part of the right end of the shell 21 is fixedly connected to the left end of the air intake pipe 1, and the middle part of the left end of the shell 21 is fixedly connected to the right end of the connecting pipe 3.

[0030] First, the air intake pipe 1 is connected to the outer shell 21. A rotating fan 23 is installed in the inner cavity of the outer shell 21, and the rotating fan 23 can rotate. When the exhaust gas enters the inner cavity of the outer shell 21 through the air intake pipe 1, the exhaust gas will blow the rotating fan 23. The rotating fan 23 rotates in the inner cavity of the outer shell 21, and then drives the transfer wheel 24 and the belt 25 to rotate, and the dust removal group 26 is driven by the belt 25 to operate.

The middle of the inner cavity of the two limiting grooves 262 is rotatably connected with a reciprocating screw 263. The upper end of the reciprocating screw 263 on the right side in the vertical direction sequentially penetrates the inner cavity top wall and upper end of the limiting groove 262 on the same side and is fixedly connected with a double-groove transmission wheel 264. The upper end of the reciprocating screw 263 on the left side in the vertical direction sequentially penetrates the inner cavity top wall and upper end of the limiting groove 262 on the same side and is fixedly connected with a transmission wheel 267. Belt 265 is wrapped around the lower part of the inner cavity of the groove transmission wheel 264, and the inner cavity of belt 265 is wrapped around the inner cavity of transmission wheel 267 on the side away from the double-groove transmission wheel 264. The inner cavities of the two reciprocating screws 263 are slidably connected with a dust removal brush 266. The inner cavity of belt one 25 is wrapped around the upper part of the inner cavity of the double-groove transmission wheel 264 on the side away from the transmission wheel one 24.

When the belt 1 25 rotates, it will drive the double-groove transmission wheel 264 to rotate, and the double-groove transmission wheel 264 will drive the belt 2 265 to rotate, and the dust removal brush 266 will drive the transmission wheel 2 267 to rotate, so that the two reciprocating screws 263 are respectively rotated at the same time in the inner cavity of the limiting groove 262. The two reciprocating screws 263 rotate at the same time, and then jointly drive the two sides of the dust removal brush 266 to slide back and forth up and down in the inner cavity of the two limiting grooves 262, so that the dust removal brush 266 removes the particulate matter on the filter plate 27, thereby achieving the purpose of filtering the particulate matter in the exhaust gas.

[0034] After the filtered waste gas enters the reaction group 62, the motor 7 is started and the limestone emulsion is allowed to enter the spray head 64 through the feed port 65 through an external device. The limestone emulsion is evenly sprayed on the waste gas through the spray head 64 to increase the contact area. At the same time, through the reaction group 62, the temperature is kept within a suitable range to accelerate the reaction of the limestone emulsion with the sulfur dioxide gas in the waste gas, thereby increasing the reaction rate. The generated precipitate and water enter the bottom seal 61. At the same time, the motor 7 drives the scraper 63 to rotate to remove the precipitate attached to the inside of the device. Finally, the reactant is discharged through the bottom seal 61 in cooperation with the discharge pipe 4, thereby achieving the purpose of harmless treatment of the waste gas.

[0036] It should be noted that the specific installation method of the thermostat 625 and the circuit connection method and control method in the present invention are all conventional designs and are conventional design means of designers.
