Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly boiler flue gas purification, and in particular to an environmentally friendly boiler flue gas purification device. Background Art

[0002] Since coal contains more substances such as sulfide and nitrate after mining, during the combustion process, sulfide and nitrate will flow with the smoke from the combustion of coal, causing sulfide and nitrate to be discharged into the air, causing sulfide and nitrate to spread and affect the living environment of the surrounding people. Therefore, it is necessary to purify the boiler smoke.

[0003] During the use of the existing environmentally friendly boiler flue gas purification device, the flue gas flows into the desulfurization chamber after dust separation. After the sprayed lime slurry comes into contact with the flue gas, the lime slurry reacts with the sulfur component in the flue gas and produces corresponding solid precipitates. This part of the precipitates gradually accumulates on the outside of the flue gas inlet channel, which will cause the flue gas to pass through. This will affect the progress of flue gas purification and reduce the use value of the environmentally friendly boiler flue gas purification device. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] An environmentally friendly boiler flue gas purification device disclosed in the present invention is mainly used in existing environmentally friendly boiler flue gas purification devices. During use, after the flue gas is separated from the dust, it flows into the desulfurization chamber. After the sprayed lime slurry contacts the flue gas, the lime slurry reacts with the sulfur component in the flue gas and produces corresponding solid precipitates. This part of the precipitates is gradually accumulated on the outside of the flue gas inlet channel, which will cause the flue gas to be blocked and affect the progress of the flue gas purification.

[0035] In a specific application scenario, when performing flue gas desulfurization treatment, the flue gas enters the bottom of the treatment tube 1201 through the circulation hole 10, and is then introduced into the interior of the treatment tube 1201 through the air hole 1205 on the conical rotating cover 1209. The precipitate produced by the reaction of the lime slurry sprayed by the spray component 4 with the lime slurry gradually falls onto the conical rotating cover 1209. At regular intervals, the drive motor 1208 is started, and the drive motor 1208 drives the conical rotating cover 1209 to rotate at high speed. The conical rotating cover 1209 in a high-speed rotating state rotates the precipitate attached to the outside of the air hole 1205 to a position close to the inner wall of the treatment tube 1201, thereby separating the precipitate from the air hole 1205, ensuring that the flue gas can pass smoothly and improving the flue gas desulfurization purification efficiency.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, a lifting rod 1204 is distributed in an annular manner on the top of the conical rotating cover 1209, and a retention rod 1203 is fixedly connected to one side of each lifting rod 1204, and a retention hole 1213 is opened at an equal distance on the top of each retention rod 1203. The retention hole 1213 is an inverted truncated cone structure, and the cross section of the retention hole 1213 is a trapezoidal structure. The side wall of the treatment cylinder 1201 located at the bottom end of the conical rotating cover 1209 is opened with two waste discharge holes, and the inside of the two waste discharge holes is clamped with a sealing ring 1212. The treatment cylinder 1201 01 The outer wall above the two blocking rings 1212 is fixedly connected with an outer ring rod 1210, and the inner wall of the outer ring rod 1210 above the blocking ring 1212 is provided with a sliding groove, and the inner sliding groove is slidably connected with an extrusion slide rod 1211, and the extrusion slide rod 1211 is in contact with the outer wall of the blocking ring 1212. The outer wall of the treatment cylinder 1201 near the bottom end is fixedly connected with a limiting plate 16, and the limiting plate 16 is in contact with the middle partition 6, the sealing door 2 and the purification box 1, and the bottom of the extrusion slide rod 1211 is in contact with the top of the limiting plate 16.

[0037] Specifically, when the flue gas desulfurization treatment chamber 12 is in working condition, part of the lime slurry does not react with the flue gas and falls on the retention rod 1203, and the lime slurry flows into the retention hole 1213. The upper opening end of the retention hole 1213 is larger, and the lower flue gas entry end is smaller. The internal diameter gradually decreases from top to bottom, thereby storing this part of the lime slurry. In the process of the flue gas flowing from bottom to top, the flue gas enters the retention hole 1213 along the micropores below the retention hole 1213 and reacts with the lime slurry, thereby improving the utilization rate of the lime slurry. At the same time, part of the lime slurry is blocked by the retention rod 1203 to prevent it from falling below and causing the air hole 1205 to be blocked.

[0038] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8In a preferred embodiment, a spray assembly 4 is provided above the treatment barrel 1201, and the spray assembly 4 includes a plurality of air guide covers 410, and the air guide covers 410 are of a funnel-like structure, and the outer sides of the plurality of air guide covers 410 are fixedly connected with the same guide sealing cover 409, and the guide sealing cover 409 is in contact with the inner wall of the treatment barrel 1201, and the plurality of air guide covers 410 are distributed in an annular manner inside the treatment barrel 1201, and the top inner wall of the purification box 1 located above the treatment barrel 1201 is fixedly connected with an inlet frame 405, and the bottom of the inlet frame 405 is provided with a diversion hole in an annular manner, and a diversion pipe 406 is inserted into the interior of each diversion hole, and each diversion pipe 406 is fixedly connected to the lower opening end A nozzle 408 is connected, and the top of each nozzle 408 is fixedly connected to a suspension rod 407, and the suspension rod 407 is fixedly connected to the bottom of the inlet frame 405. The nozzle 408 is located inside the air guide cover 410, and there is a gap between the nozzle 408 and the air guide cover 410. The top of the purification box 1 located above the treatment cylinder 1201 is provided with a row of holes 5, and the side of the purification box 1 close to the inlet frame 405 is fixedly connected to a pump ring frame 403, and the inside of the pump ring frame 403 is fixedly connected to a delivery pump 401, and the delivery end of the delivery pump 401 is fixedly connected to a delivery pipe 402, one end of the delivery pipe 402 is inserted into the inside of the inlet frame 405, and the extraction end of the delivery pump 401 is fixedly connected to a liquid extraction pipe 404.

[0039] It should be noted that during the spraying operation of the lime slurry, the flue gas is introduced into each air guide cover 410 along the guide sealing cover 409, and the nozzle 408 is directly inserted into the air guide cover 410. The flue gas accumulated below flows upward, and the coverage area of ​​the lime slurry sprayed by the nozzle 408 is much larger than the flue gas flow area, ensuring that the flue gas will inevitably contact and react with the lime slurry on the way up, achieving efficient desulfurization and improving the flue gas desulfurization effect. After desulfurization, the flue gas is discharged along the gap between the nozzle 408 and the air guide cover 410 to complete the flue gas purification operation.

[0040] Reference Figure 1 , Figure 2 and Fig. 9 In a preferred embodiment, two lifting guide rails 8 are fixedly connected to the bottom inner wall of the purification box 1 on the other side of the middle partition 6, and the inside of the two lifting guide rails 8 are slidably connected with lifting sliders 18, and a flue gas dust removal treatment chamber 9 is provided on the opposite side of the two lifting sliders 18. The two lifting guide rails 8 are fixedly connected to a blocking block on one side below the two lifting sliders 18, and the blocking block is in contact with the bottom of the lifting slider 18. The outer sides of the two lifting guide rails 8 are fixedly connected with the same partition plate 17, and the partition plate 17 is in contact with the middle partition 6 and the inner side wall of the purification box 1. The tops of the two lifting sliders 18 are fixedly connected with pull rods 7, and the top of the partition plate 17 is provided with a through hole 1207.

[0041] Reference Figure 1, Figure 2 , Fig. 9 , Fig.10 and Fig.11 In a preferred embodiment, the flue gas dust removal treatment chamber 9 includes a straight cylinder 902 and a filter bag 903, and the filter bag 903 is fixedly connected to the bottom of the straight cylinder 902, the straight cylinder 902 passes through the through hole 1207, the straight cylinder 902 is fixedly connected to the opposite side of the two lifting sliders 18, and the outer wall of the straight cylinder 902 is fixedly connected to two fitting seats 913, the tops of the two fitting seats 913 are fixedly connected to hydraulic cylinders 912, the output ends of the two hydraulic cylinders 912 are fixedly connected to lifting blocks 911, and the bottoms of the two lifting blocks 911 are fixedly connected to the same top cover 901, and the top cover 901 is in contact with the top of the straight cylinder 902.

The outer side of the hollow rotating tube 921 located inside the filter bag 903 is annularly distributed with connecting thin rods 922. The end of each connecting thin rod 922 is fixedly connected to an oscillating ball 905, and the oscillating ball 905 is in contact with the inner wall of the filter bag 903.

[0042] In a specific application scenario, when performing preliminary dust removal treatment on the flue gas, start the air pump 909, which guides the flue gas into the hollow rotating tube 921 so that the flue gas is guided to the bottom of the filter bag 903. Start the drive motor 915, which drives the hollow rotating tube 921 to rotate slowly. During the rotation, each oscillation ball 905 contacts the filter bag 903 and collides slightly, so that the filter bag 903 is in an oscillating state, thereby accelerating the separation of the flue gas from the filter bag 903 and improving the dust removal efficiency of the flue gas.

[0043] Specifically, when the filter bag 903 needs to be cleaned after being used for a period of time, the hydraulic cylinder 912 is adjusted to drive the top cover 901 to rise, and the hollow rotating tube 921 drives the filter bag 903 to present a flipped state.

The driving motor 915 is started again, and the driving motor 915 drives each oscillation ball 905 to rotate slowly. The rotating oscillation ball 905 collides and oscillates the inside of the filter bag 903, so that the dust attached to the inside of the filter bag 903 can fall off quickly, thereby accelerating the cleaning process of the filter bag 903 and improving the convenience of cleaning the filter bag 903.

The driving motor 915 drives the hollow rotating tube 921 to rotate slowly. During the rotation, each oscillation ball 905 contacts and slightly collides with the filter bag 903, so that the filter bag 903 is in an oscillating state, accelerating the smoke to separate from the filter bag 903. The smoke that separates from the filter bag 903 enters the bottom of the treatment tube 1201 along the flow hole 10, and then is introduced into the interior of the treatment tube 1201 through the air hole 1205 on the conical rotating cover 1209. The smoke is introduced into each air guide cover 410 along the guide sealing cover 409, and the nozzle 408 is directly inserted into the air guide cover In 410, the flue gas accumulated at the bottom flows upward, and the coverage area of ​​the lime slurry sprayed from the nozzle 408 is much larger than the flue gas flow area, ensuring that the flue gas will inevitably contact and react with the lime slurry on the way up. After desulfurization, the flue gas is discharged along the gap between the nozzle 408 and the air guide cover 410 to complete the flue gas purification operation. After the purification device has been used for a period of time, the drive motor 1208 is started, and the drive motor 1208 drives the conical rotating cover 1209 to rotate at a high speed. The conical rotating cover 1209 in a high-speed rotating state rotates the precipitate attached to the outside of the air hole 1205 to a position close to the inner wall of the treatment cylinder 1201, thereby separating the precipitate from the air hole 1205, ensuring that the flue gas can pass smoothly and continue the flue gas purification operation.
