Description

Technical Field

[0001] This utility model relates to the field of power plant pollutant treatment technology, specifically a waste gas and wastewater treatment equipment and boiler for power plants. Background Technology

[0002] Power plants generate large amounts of flue gas when burning fuels such as coal, oil, or natural gas. This flue gas contains harmful substances such as carbon dioxide, sulfur dioxide, nitrogen oxides, particulate matter, and trace amounts of heavy metals. During boiler combustion, wastewater containing pollutants such as suspended solids and heavy metals is produced. Therefore, waste gas and wastewater treatment equipment is needed for purification.

[0003] Most existing power plant pollutant treatment equipment can only treat wastewater or exhaust gas, making it inconvenient to treat both simultaneously, thus reducing treatment efficiency. Furthermore, the slow dissolution rate of solid purifying agents reduces the speed of wastewater treatment.

[0004] Based on this, we now provide a waste gas and wastewater treatment device for power plants that can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a waste gas and wastewater treatment device for power plants includes a base 1. The top of the base 1 is respectively provided with a waste gas treatment mechanism 2, a filtration mechanism 4 and a purification tank 6. The purification tank 6 is provided with a mixing mechanism 7 inside and a crushing mechanism 8 on the top of the purification tank 6. A first water pump 3 is provided between the waste gas treatment mechanism 2 and the filtration mechanism 4. A second water pump 5 is provided between the filtration mechanism 4 and the purification tank 6. A third water pump 9 is provided on one side of the purification tank 6. The first water pump 3, the second water pump 5 and the third water pump 9 are all fixedly installed on the base 1.

[0028] In this embodiment, wastewater and exhaust gas enter the interior of the exhaust gas treatment unit 2, where the exhaust gas is purified. The wastewater generated from the purified exhaust gas, along with the wastewater, is introduced into the interior of the filtration unit 4 by the first water pump 3. The filtration unit 4 can filter the wastewater, effectively removing impurities from the wastewater. At the same time, the impurities are collected for subsequent cleaning. The filtered wastewater is then introduced into the purification tank 6 by the second water pump 5. The wastewater purification agent is ground and pulverized by the pulverizing unit 8, allowing the purification agent to dissolve quickly in the wastewater. The mixing unit 7 further increases the dissolution rate of the purification agent and mixes the purification agent with the wastewater, thereby improving the purification efficiency.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the waste gas treatment mechanism 2 includes a feed tank 21, which is fixedly installed on the top of the base 1. An air inlet pipe 23 and a water inlet pipe 22 are fixedly installed on one side of the feed tank 21, with the air inlet pipe 23 located above the water inlet pipe 22. An air outlet pipe 25 is fixedly installed on the top of the feed tank 21. Two washing pipes 24 are fixedly installed inside the feed tank 21. Waste gas enters the interior of the feed tank 21 through the air inlet pipe 23, and the washing pipe 24 sprays out waste gas absorption liquid, effectively purifying the waste gas. The generated wastewater is collected at the bottom of the feed tank 21 and introduced into the interior of the feed tank 21 through the water inlet pipe 22. With the operation of the first water pump 3, the wastewater and sewage are introduced into the interior of the filter mechanism 4.

[0030] In one embodiment, such as Figure 1 and Figure 3 As shown, the filtration mechanism 4 includes a filter pool 41, which is fixedly installed on the top of the base 1. The filter pool 41 has equidistant grooves 42 on both sides inside. A filter plate 43 is slidably installed between every two grooves 42. A collection component is provided on one side of the filter plate 43. The collection component includes a collection box 44, which is fixedly installed on one side of the filter plate 43. The aperture of the multiple filter plates 43 decreases sequentially. Impurities in the sewage can be filtered through the multiple filter plates 43. The filtered impurities will fall into the collection box 44 due to gravity. When it is necessary to clean the filter plates 43, the filter plates 43 can be easily removed and cleaned through the grooves 42.

[0031] In one embodiment, such as Figure 1 and Figure 4As shown, the mixing mechanism 7 includes a mixing rod 71, which is rotatably installed inside the purification tank 6. A motor 72 is fixedly installed on the other side of the purification tank 6, and the output end of the motor 72 is connected to the mixing rod 71. The motor 72 drives the mixing rod 71 to rotate. The slow rotation of the mixing rod 71 allows the pulverized purifying agent to be fully mixed with the sewage, while accelerating the dissolution rate of the purifying agent and improving the efficiency of sewage purification.

[0032] In one embodiment, such as Figure 1 and Figure 5 As shown, the crushing mechanism 8 includes a mounting plate 81, which is fixedly installed on the top of the purification tank 6. Support rods 82 are fixedly installed at the four corners of the top of the mounting plate 81. A top plate 83 is fixedly installed on the top of the four support rods 82. A hydraulic cylinder 84 is fixedly installed on the top of the top plate 83. The output end of the hydraulic cylinder 84 passes through the top plate 83 and is fixedly installed with a lifting plate 85. The lifting plate 85 is slidably installed with the support rods 82. A grinding assembly is provided on the top of the lifting plate 85. The grinding assembly includes a drive assembly 86, which is fixedly installed on the top of the lifting plate 85. The output end of the drive assembly 86 passes through the lifting plate 85 and is connected to a grinding wheel 8. 7. The top of the mounting plate 81 is provided with a sieving assembly, which includes a grinding bucket 88. The grinding bucket 88 is fixedly installed on the top of the mounting plate 81 and is located directly below the grinding wheel 87. A sieve plate 89 is installed inside the grinding bucket 88. The purifying agent to be pulverized is put into the grinding bucket 88. The hydraulic cylinder 84 drives the lifting plate 85 to move downward. The grinding wheel 87 enters the grinding bucket 88 and contacts the purifying agent. The drive assembly 86 drives the grinding wheel 87 to rotate. The rotating grinding wheel 87 pulverizes the purifying agent. The pulverized purifying agent falls into the wastewater through the sieve plate 89, while larger particles of purifying agent continue to be pulverized, thus improving the efficiency of wastewater treatment.

[0033] The above embodiment discloses a waste gas and wastewater treatment device for a power plant. Waste gas enters the feed tank 21 through the inlet pipe 23, and a waste gas absorption liquid is sprayed from the washing pipe 24 to effectively purify the waste gas. The generated wastewater collects at the bottom of the feed tank 21 and is introduced into the feed tank 21 through the water inlet pipe 22. A first water pump 3 operates, and the wastewater and wastewater are introduced together into the filter mechanism 4. The apertures of multiple filter plates 43 decrease sequentially, allowing impurities in the wastewater to be filtered out. The filtered impurities fall into the collection tank 44 due to gravity, and the filtered wastewater then enters the purification system. Inside pool 6, the purifying agent to be pulverized is placed inside the grinding hopper 88. The hydraulic cylinder 84 drives the lifting plate 85 to move downwards, and the grinding wheel 87 enters the grinding hopper 88 to contact the purifying agent. The drive assembly 86 drives the grinding wheel 87 to rotate, and the grinding wheel 87 pulverizes the purifying agent. The pulverized purifying agent falls into the wastewater through the sieve plate 89, while larger particles of purifying agent continue to be pulverized. The motor 72 drives the mixing rod 71 to rotate. The slow rotation of the mixing rod 71 ensures that the pulverized purifying agent is fully mixed with the wastewater, while also accelerating the dissolution rate of the purifying agent and improving the efficiency of wastewater purification.
