Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a device for treating mercury-containing waste gas. Background Technology

[0002] Mercury is a liquid metal that can evaporate at room temperature and enter the atmosphere. Mercury in the air includes mercury vapor and mercury compound dust. Mercury emissions mainly come from human activities, including mercury mining and smelting, mining and smelting of gold, silver and lead symbiotic ores, some mercury product and mercury compound production plants, chlor-alkali plants and organic chemical plants that use mercury, gold distillation sites, as well as fossil fuel combustion and waste incinerators, all of which emit mercury pollutants. Among these, coal-fired power plants are the most important source of mercury emissions into the atmosphere.

[0003] A current device for treating mercury-containing waste gas, as described in patent CN213160162U, comprises a treatment chamber, a connecting chamber at one end of which is fitted with a negative pressure fan. The treatment chamber contains an installation ring, and inside the installation ring is a filter ring. The filter ring contains, in sequence, a resin filter layer, an activated carbon filter layer, and a molecular sieve filter layer. Ball bearings are evenly distributed at the contact points between the filter ring and the installation ring. This device includes a connecting chamber, a negative pressure fan, a dust filter, a connecting pipe, an exhaust fan, a reaction liquid storage chamber, and a one-way valve. The negative pressure fan and exhaust fan extract and move the gas, facilitating its injection into the reaction liquid storage chamber for thorough reaction and absorption of airborne mercury. Subsequent separation equipment performs separation and recovery. The resin filter layer, activated carbon filter layer, and molecular sieve filter layer provide initial filtration before the reaction absorption.

[0004] Regarding the aforementioned related technologies, the applicant discovered that a mercury-containing waste gas treatment device filters dust from the air using a dust filter. However, the negative pressure fan is constantly operating, causing dust to easily accumulate on the dust filter. This necessitates frequent disassembly of the dust filter, increasing the user's workload. If disassembly is not performed, the filtration efficiency of the dust filter is directly affected, impacting the efficiency of mercury waste gas treatment. Therefore, we propose a mercury-containing waste gas treatment device. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0033] Please see Figure 1 and Figure 2 The diagram shows a mercury-containing waste gas treatment device, including a treatment chamber 1 and an inlet 101. A sealing door 102 is hinged to the outer wall of the treatment chamber 1. A filter mechanism 2 is installed inside the treatment chamber 1. The filter mechanism 2 includes a drive motor 201, which is fixedly installed between the drive motor 201 and the treatment chamber 1. A rotating shaft 202 is fixedly connected to the output end of the drive motor 201. Filter plates 203 are fixedly installed on the outer wall of the rotating shaft 202 via a fixing sleeve. Three filter plates 203 are provided, each containing a resin filter layer, an activated carbon filter layer, and a molecular sieve filter layer, respectively. A filter layer and a processing chamber 1 are fixedly installed with an exhaust fan 204 on the side of the outer wall away from the fixed plate 301. The exhaust end of the exhaust fan 204 is fixedly provided with an exhaust pipe 2041, which is connected to the interior of the processing chamber 1. The exhaust end of the exhaust fan 204 is fixedly provided with an exhaust pipe 2042. A reaction chamber 205 is provided on the top of the exhaust pipe 2042. A visualization glass is installed on the outer wall of the reaction chamber 205. The interior of the reaction chamber 205 is filled with a reaction liquid. The reaction chamber 205 is fixedly connected to the processing chamber 1. The exhaust pipe 2042 is connected to the interior of the reaction chamber 205 through a one-way valve.

[0034] An air intake mechanism 3 is installed on one side of the outer wall of the processing chamber 1 near the inlet 101. The air intake mechanism 3 includes a fixed plate 301, which is fixedly connected to the processing chamber 1. A first partition 3011 is fixedly installed inside the fixed plate 301. A second partition 3012 is fixedly installed inside the fixed plate 301 near the first partition 3011. A filter partition 3013 is detachably connected inside the second partition 3012. There is damping between the filter partition 3013, the fixed plate 301, and the second partition 3012 to ensure the sealing of the fixed plate 301 during normal use of the second partition 3012. A drive motor 302 is fixedly installed on one side of the outer wall of the first partition 3011. One end of the output shaft of the drive motor 302 is connected to a drive shaft 304 via a first drive belt 303. A fan blade 305 is fixedly mounted on one end of the drive shaft 304. A fixed seat 306 is sleeved on the outer wall of the drive shaft 304. The fixed seat 306 is rotatably connected to the drive shaft 304. The fixed seat 306 is fixedly connected to the fixed plate 301. The drive shaft 304 is connected to a dust removal assembly 308 via a second drive belt 307. The dust removal assembly 308 is provided with a drive rod 3081. The drive rod 3081 is rotatably connected to the first partition 3011 and the second partition 3012. One end of the drive rod 3081 is connected to a cleaning brush 3083 via a third drive belt 3082. One side of the cleaning brush 3083 is in contact with the outer wall of the filter partition 3013. A fixed frame 3084 is fixedly mounted on the outer wall of the second partition 3012. One side of the cleaning brush 3083 is rotatably connected to the fixed frame 3084.

[0035] When using the device, place it in the designated location, then turn on the drive motor 302, drive motor 201, exhaust fan 204, and check valve. Driven by the drive motor 302, and driven by the first drive belt 303 and drive shaft 304, the mercury-containing waste gas is drawn into the treatment chamber 1 through the filter plate 3013 and the inlet 101 via the fan blades 305. The drive motor 201 drives the rotating shaft 202, causing the mercury-containing waste gas entering the treatment chamber 1 to be filtered and treated by the resin filter layer, activated carbon filter layer, and molecular sieve filter layer inside the rotating filter plate 203. The filtered gas is then extracted through the exhaust pipe 2041 and injected into the reaction chamber 205 through the exhaust pipe 2042 for reaction filtration. Finally, the gas that has undergone secondary treatment is discharged. The reaction chamber 205 can be observed through the visualization glass on the reaction chamber 205. The internal reaction liquid is replenished in a timely manner. When the filter plate 203 and filter partition 3013 need to be replaced periodically, the filter plate 203 can be disassembled and replaced by opening the sealing door 102. The filter partition 3013 can be replaced by pulling it upward. During the rotation of the drive shaft 304, the drive rod 3081, the third drive belt 3082 and the cleaning brush 3083 are driven in sequence by the second drive belt 307. The rotation of the cleaning brush 3083 effectively cleans the dust on the filter partition 3013. Then, driven by the drive motor 302 in the air intake mechanism 3, without consuming additional energy, not only is the exhaust gas drawn in, but the cleaning brush 3083 in the dust removal component 308 also effectively cleans the dust on the filter partition 3013. This improves the energy utilization rate and effectively ensures the efficiency of mercury exhaust gas treatment.

[0036] Please see Figures 1-6 In the figure, a collection component 4 is installed on the outer wall of the fixed plate 301 near the second partition 3012. The collection component 4 includes a collection box 401. A guide groove 3014 is provided on the outer wall of the second partition 3012 near the collection box 401. The collection box 401 is in contact with the second partition 3012. A limiting plate 402 is fixed on one side of the outer wall of the collection box 401. An installation groove 4021 for the limiting plate 402 to be inserted is provided on the outer wall of the second partition 3012. A snap-fit ​​block 403 is fixed on the outer wall of the limiting plate 402. The snap-fit ​​block 403 is made of elastic plastic material. A slot for the snap-fit ​​block 403 to be snapped into is provided on the inner wall of the installation groove 4021.

[0037] When the dust and impurities cleaned by the dust removal component 308 are collected, the dust on the filter baffle 3013 is cleaned by the cleaning brush 3083. Due to gravity, the dust and impurities are automatically pushed down into the collection box 401 by the guide groove 3014 under the rotation of the cleaning brush 3083, and are collected in a concentrated manner by the collection box 401. When it is necessary to periodically clean the dust in the collection box 401, the collection box 401 is pulled outward, causing the collection box 401 to move synchronously with the limiting plate 402 and the snap-fit ​​block 403 in the mounting groove 4021. This causes the snap-fit ​​block 403 to disengage from the slot in the mounting groove 4021. After the dust in the collection box 401 is cleaned, the collection box 401 is fixed to the second partition 3012 again through the snap-fit ​​between the limiting plate 402, the snap-fit ​​block 403, the mounting groove 4021, and the slot. Thus, through the setting of the collection box 401 and the limiting plate 402 in the collection assembly 4, the dust on the filter partition 3013 is effectively collected after cleaning. At the same time, through the cooperation of the limiting plate 402 and the mounting groove 4021, the collection box 401 is effectively fixed after installation, ensuring the stable collection of dust on the filter partition 3013.
