Description

Technical Field

[0001] This utility model belongs to the field of flue gas treatment technology, specifically relating to a flue gas activated carbon adsorption device. Background Technology

[0002] Activated carbon adsorption devices for flue gas are tools used to treat industrial waste gas. They work by rapidly eroding the inner wall of pipes with fly ash carried in high-temperature flue gas, especially at bends and diameter changes. For example, the outer wall thickness of a DN800 pipe bend may decrease by 0.5mm-1mm per year, potentially wearing through after 3 years, leading to leaks. When the leak point is near the high-temperature section, the entry of cold air can cause a sudden drop in local flue gas temperature. When the temperature drops below the acid dew point, water vapor combines with sulfur trioxide to form sulfuric acid mist, which condenses on the activated carbon surface, clogging micropores and corroding the equipment, thus affecting its normal operation. Utility Model Content

[0003] This utility model provides a flue gas activated carbon adsorption device, which avoids the impact of flue gas on the bend of the bend when passing through it, reduces wear on the bend of the bend, and reduces the impact of the flue gas during transportation on the bend of the bend during long-term use.

[0017] Please see Figures 1-3This utility model provides the following technical solution: a flue gas activated carbon adsorption device, including an adsorption component body 1, a bent gas supply pipe 2 fixedly connected to the lower end of one side of the adsorption component body 1, a connecting pipe 21 fixedly connected to the top of the bent gas supply pipe 2, guide plates 3 installed on both sides of the inner chamber of the bent gas supply pipe 2, a connecting top plate 31 fixedly connected to the top of the guide plate 3, an installation chamber 32 opened inside the guide plate 3, a filter screen 4 installed inside the installation chamber 32, and a filter cotton 41 fixedly connected inside the filter screen 4, an inner mounting seat 33 fixedly connected to one side of the guide plate 3, and the guide plate 3 installed inside the bent gas supply pipe 2 through the inner mounting seat 33, a rubber soft plate 35 fixedly connected to the end of the guide plate 3, an outer reinforcing arc plate 22 fixedly connected to the outer side of the bent gas supply pipe 2, and an inner reinforcing arc plate 221 fixedly connected to the inner side of the bent gas supply pipe 2.

[0018] In this implementation scheme: the adsorption component body 1 is the main body of the entire adsorption device. The elbow gas conveying pipe 2, in cooperation with the connecting pipe 21, forms a conveying component for conveying flue gas. The outer reinforcing arc plate 22 located outside the elbow gas conveying pipe 2 and the inner reinforcing arc plate 221 located inside the elbow gas conveying pipe 2 are used to reinforce the elbow of the elbow gas conveying pipe 2. The guide plate 3 installed inside the elbow gas conveying pipe 2 is used to guide the flue gas in the elbow gas conveying pipe 2 as it passes through the elbow, avoiding impact on the elbow of the elbow gas conveying pipe 2 when the flue gas passes through it. This reduces wear on the elbow of the elbow gas conveying pipe 2 and reduces the impact force generated by the flue gas during the conveying process on the elbow of the elbow gas conveying pipe 2 during long-term use. The mounting chamber 32 in the guide plate 3 provides space for the filter screen 4 to be installed. The filter screen 4, in cooperation with the filter cotton 41, forms a workpiece that adsorbs particles in the flue gas. When the flue gas passes through the guide plate 3, the guide plate 3 can adsorb particles in the flue gas, reducing impurities in the flue gas. The connecting top plate 31 at the top of the guide plate 3 is used to protect the filter screen 4 and prevent it from falling out of the mounting chamber 32. The inner mounting seat 33 on one side of the guide plate 3 is used to provide a carrier for the connection between the guide plate 3 and the inner wall of the elbow gas pipe 2. The rubber soft plate 35 at the end of the guide plate 3 is used to further guide the flue gas. At the same time, the rubber soft plate 35 is made of soft material, which can buffer the impact force generated by the flue gas during the transportation process.

[0019] The top plate 31 has several connecting holes 311 inside; the connecting holes 311 are used to provide space for the filter screen 4 and filter cotton 41 to contact the flue gas.

[0020] A support plate 351 is embedded inside the rubber flexible sheet 35; the support plate 351 plays a supporting role.

[0021] An outer mounting base 34 is installed on the outer side of the adsorption component body 1, and an anti-slip pad 341 is fixedly connected to the inner side of the outer mounting base 34. The outer mounting base 34 is used to provide a carrier for the connection between the inner mounting base 33 and the wall of the elbow gas pipe 2. When the guide plate 3 is installed inside the elbow gas pipe 2, the guide plate 3 and the elbow gas pipe 2 can be fixed by inserting the inner mounting base 33 into the elbow gas pipe 2 and then fixing it to the elbow gas pipe 2 by the outer mounting base 34 outside the elbow gas pipe 2.

[0022] Both the interior of the elbow gas pipe 2 and the interior of the inner mounting base 33 are provided with a second mounting groove 24; the second mounting groove 24 is used to provide space for the threaded rod 342 to be installed.

[0023] The second mounting groove 24 is internally threaded to the outer mounting base 34 with a threaded rod 342; the threaded rod 342 is used to fix the outer mounting base 34 to the elbow gas pipe 2.

[0024] The inside of the elbow gas pipe 2 is provided with a first mounting groove 23, and the inner mounting seat 33 is fixedly connected to the outer mounting seat 34 through the first mounting groove 23; wherein the first mounting groove 23 is used to provide space for the inner mounting seat 33 to be installed.

[0025] The working principle and usage process of this utility model are as follows: When the entire adsorption device adsorbs and fixes the flue gas, the flue gas enters the interior of the elbow gas supply pipe 2 through the connecting pipe 21. The guide plate 3 in the elbow gas supply pipe 2 can guide the flue gas and prevent the flue gas from directly impacting the elbow of the elbow gas supply pipe 2. The rubber soft plate 35 can buffer the impact force generated during the flue gas transportation process. When the flue gas passes through the guide plate 3, the filter screen 4 and the filter cotton 41 can filter the impurities in the flue gas. After long-term use, the connecting pipe 21 can be separated from the elbow gas supply pipe 2, and then the outer mounting base 34 can be separated from the elbow gas supply pipe 2. The guide plate 3 can be disassembled from the elbow gas supply pipe 2 and replaced.
