Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection devices, and in particular to an environmental protection construction desulfurization device and a construction method thereof. Background Art

[0002] A desulfurization tower generally refers to a tower-type equipment for desulfurizing industrial waste gas. The current desulfurization tower generally includes a vertically arranged side tower body, a smoke inlet is arranged in the lower middle part of the tower body, a smoke outlet is arranged on the top of the tower body, and a nozzle is also arranged on the upper inner side of the tower body. Desulfurization slurry is placed at the bottom, and flue gas can enter from the smoke inlet and be discharged upward from the smoke outlet. During this process, the nozzle can spray desulfurization slurry in the opposite direction of the flue gas flow to achieve the purpose of flue gas desulfurization. For example, the application document with application number CN202211461664.9 discloses an efficient desulfurization tower tray for a desulfurization tower, and its nozzle adopts a multi-layer design and sprays desulfurization in the opposite direction of the flue gas flow. This direct-through transportation method of flue gas in the desulfurization tower results in that the flue gas can only be reserved for a limited time in the desulfurization tower. Within the limited time or when the flue gas volume is large, its desulfurization work in the desulfurization tower is difficult to complete efficiently.

[0003] At the same time, even though the nozzles of existing desulfurization towers usually adopt a multi-layer design, in order to ensure the fluidity of the flue gas in the desulfurization tower, the arrangement of the nozzles still cannot be too dense, which has also become the main factor restricting the flue gas desulfurization efficiency. For example, the application document with application number CN201320527965.7 discloses a spray-type tower plate desulfurization tower, which is a plurality of tower plates staggered inside the desulfurization tower to provide a guide for the flue gas and avoid spraying dead corners. However, this arrangement, on the one hand, will seriously affect the smoothness of the flue gas running inside the desulfurization tower, causing poor smoke intake or exhaust. On the other hand, since the flue gas generally flows close to the lower plate surface of the tower plate, the nozzle is arranged below the tower plate, so that the spray desulfurization process still has spraying dead corners, so there are still limitations in desulfurization. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an environmentally friendly construction desulfurization device and a construction method thereof.

[0005] The technical solution of the present invention is as follows:

[0006] The present invention first provides an environmentally friendly construction desulfurization device, including a base and several layers of intermediate towers on its upper side, the adjacent intermediate towers are detachably connected, and the upper side of the uppermost intermediate tower is detachably connected with a top tower, the intermediate tower includes a vertical cylindrical tower body, a smoke inlet pipe is provided on one side of the tower body of the lowest intermediate tower, the top tower includes a tower cover buckled on the uppermost intermediate tower, a smoke outlet pipe is provided on the upper side of the tower cover, the flue gas to be desulfurized can enter the desulfurization device (the above-mentioned environmentally friendly construction desulfurization device) from the smoke inlet pipe, and pass through several layers of intermediate towers from bottom to top, and then be discharged from the smoke outlet pipe of the top tower under the desulfurization action of the several layers of intermediate towers, thereby completing the desulfurization of the flue gas.

[0007] Specifically speaking about the structure of the desulfurization device, a pulp pool is provided on the upper side of the base, and desulfurized slurry is contained in the pulp pool. A water pump connected to the inside of the pulp pool is also provided on one side of the base. As one of the core technical concepts of the present invention, the intermediate tower includes a vertical cylindrical tower body, and a desulfurization system is provided on one side of the inner side of the tower body. The desulfurization system includes a main board hingedly connected to the inner wall of the tower body on one side, and a first desulfurization unit is provided on the other side of the main board. The desulfurization system also includes a traction unit transmission-connected to the main board, which is configured to be able to drive the main board to rotate. At the same time, the desulfurization systems inside adjacent intermediate towers are staggered. The main board can be tilted under the drive of the traction unit, and cooperate with the staggered setting of the adjacent first desulfurization unit. At this time, the flue gas entering from the smoke inlet pipe can run upward in a curved shape under the action of the main board, that is, the setting of the main board makes the flue gas, when flowing through the main board position, concentrate and tilt upward close to the lower side of the main board under the action of circulation, so as to increase the reserved time of the flue gas inside the desulfurization device, and at the same time avoid the main board setting to have a greater impact on the flue gas flowability, but have a certain buffering effect on the circulation of the flue gas, cooperate with the setting of the first desulfurization unit, and complete the flue gas desulfurization work in the process of flue gas circulation along the main board.

[0008] On the basis of the above structure, as another core technical concept of the present invention, the first desulfurization unit includes a first water pipe arranged on the lower side of the main board and whose axis is parallel to the rotation axis of the main board. The desulfurization system also includes a pipe joint arranged on the tower body, and the inner end of the pipe joint is connected to the first water pipe through a hose. A water pump connecting the slurry pool and the pipe joint is also provided on one side of the base. A plurality of first water nozzles are linearly arranged along the length direction of the first water pipe. The direction of the water outlet of the first water nozzle is perpendicular to the axis of the first water pipe, parallel to the plate surface of the main board, and toward the hinged connection side of the main board. Through this arrangement, when the flue gas is inclined upward along the lower side of the main board, the first water nozzle located on the lower side of the main board can spray the desulfurization slurry in the opposite direction of the flue gas flow direction, so as to prevent the occurrence of spraying dead corners during the flue gas circulation process and ensure the flue gas desulfurization efficiency.

[0009] As a further preferred core technical concept, a plurality of second water nozzles are linearly arranged along the length direction of the first water pipe, and the directions of the water outlets of the plurality of second water nozzles are perpendicular to the axis of the first water pipe, and form an angle of 40-50 degrees with the direction of the water outlets of the first water nozzles, and are located on the side of the first water nozzle away from the main board. Therefore, when the amount of flue gas is large, that is, when the flue gas inclined upward along the lower side of the main board is thicker, the flue gas desulfurization work can still be better completed through the second water nozzles, thereby further ensuring the flue gas desulfurization efficiency.

[0010] As an environmentally friendly construction desulfurization device as described above, as a preferred embodiment, in order to prevent the interference between the operations of the first water nozzle and the second water nozzle while ensuring that flue gas desulfurization can be fully carried out, a number of the second water nozzles are staggered with a number of the first water nozzles, and the direction of the water outlets of the second water nozzles is at a 45-degree angle to the direction of the water outlets of the first water nozzles.

[0011] In an environmentally friendly construction desulfurization device as described above, a smoke hole is also provided on the main board, and a second desulfurization unit is also provided inside the other intermediate towers except the lowest intermediate tower and on the side away from the desulfurization system. The second desulfurization unit includes a main water pipe arranged on the tower body, and several rows of second water pipes arranged inside the tower body. The axis of the second water pipe is parallel to the rotation axis of the main board. The second water pipe is linearly arranged along its length direction with several third water nozzles facing downward. Through this arrangement, when the flue gas volume is large, part of the flue gas can directly ascend along the hole and cooperate with the third water nozzle to complete the desulfurization work, while further preventing the arrangement of the main board from affecting the circulation of the flue gas when the flue gas volume is large.

[0012] In order to ensure the desulfurization effect of the second desulfurization unit, the smoke holes are densely distributed in plurality.

[0013] As a preferred embodiment, the main board is also provided with an adjustment unit capable of adjusting the opening and closing state of the smoke vent, so that when the flue gas flow changes, the amount of flue gas passing through the smoke vent can be adjusted through the adjustment unit, so that the separation flow device can better complete the flue gas desulfurization work at different flue gas volumes.

[0014] Specifically, the adjustment unit includes an insert plate that is slidably arranged on the main board surface, and a telescopic driving cylinder that can drive the insert plate to slide. The smoke hole is a long strip structure arranged along the sliding direction of the insert plate, so that the smoke flow through the smoke hole can be more easily controlled through the action of the telescopic driving cylinder.

[0015] As a further preferred embodiment, the desulfurization device also includes a control system, and the smoke inlet pipe is provided with a first detection unit capable of detecting the flue gas flow rate. The first detection unit and the adjustment unit are both communicatively connected to the control system, and the control system is configured to control the action of the adjustment unit and thereby control the amount of smoke passing through the vent hole according to a feedback value of the first detection unit, so that the amount of smoke passing through the smoke hole can be automatically controlled according to the smoke intake of the smoke inlet pipe, thereby ensuring that the flue gas desulfurization work can be carried out in a more intelligent and automated manner.

[0016] More preferably, the smoke outlet pipe is provided with a second detection unit capable of detecting the sulfur content in the flue gas, the second detection unit and the traction unit are both communicatively connected to the control system, and the control system is configured to control the action of the traction unit and thus control the inclination angle of the main board according to the feedback value of the second detection unit, so that the inclination state of the main board can be automatically controlled according to the sulfur content in the flue gas after desulfurization, thereby ensuring the adequacy of flue gas desulfurization and at the same time ensuring that the flue gas desulfurization work can be carried out in a more intelligent and automated manner.

[0017] The present invention also provides a method for constructing the above-mentioned environmentally friendly construction desulfurization device, which specifically comprises the following steps:

[0018] S1: build the base;

[0019] S1.1: Build the base with brick or stone according to the specifications of the tower;

[0020] S1.2: Apply waterproof and alkali-resistant coating in the pulp tank;

[0021] S1.3: Install the water pump;

[0022] S1.4: inject desulfurized slurry into the slurry pool;

[0023] S2: Install the intermediate tower;

[0024] S2.1: With the tower body as the basis, assemble the desulfurization system on it, and adjust the main board to tilt upward on the side away from the hinged connection;

[0025] The height of the main board away from the hinged connection side does not exceed the upper edge of the tower body, so as to ensure that the installation of the intermediate tower can be more convenient and avoid the interference of the setting of the desulfurization system on the assembly of the intermediate tower. The inclination angles of the main boards inside the tower bodies are the same, so that the inclination angle of the main boards can be adjusted more conveniently after the assembly is completed.

[0026] S2.2: assemble the assembled intermediate towers in sequence from bottom to top;

[0027] S3: Install the top tower;

[0028] S4: Adjust the main board;

[0029] The inclination angle of the main board inside each tower body is adjusted by the traction unit, so that the inclination angle of the lower main board of the middle tower of two adjacent layers is greater than that of the upper main board, so that the flue gas entering from the smoke inlet pipe can have better fluidity, and prevent the phenomenon of poor smoke inlet caused by clogging of the smoke inlet pipe. At the same time, the bottom desulfurization system completes the initial desulfurization work, and in the process of flue gas upward, the buffering effect of flue gas is gradually increased, and finally the flue gas desulfurization work is carried out step by step, ensuring that the flue gas desulfurization work can be more sufficient;

[0030] S5: Connect the water pump and the pipe joint.

[0031] It should be noted that in step S4, the inclination angle of any main board is in the range of 15-50 degrees, which ensures that the main board has a better guiding effect on the smoke while preventing the setting of the main board from having a significant impact on the smoke flowability.

[0032] The beneficial effects of the present invention are:

[0033] (1) The present invention provides an environmentally friendly construction desulfurization device and a construction method thereof. The main board of the desulfurization system and the first desulfurization unit thereon are arranged so that the flue gas entering from the smoke inlet pipe can bend upward under the action of the main board. That is, the arrangement of the main board enables the flue gas to be concentrated and tilted upward close to the lower side of the main board when flowing through the main board. This increases the reserved time of the flue gas inside the desulfurization device and avoids the main board arrangement from having a significant impact on the flue gas flowability. It also has a certain buffering effect on the flow of the flue gas. In conjunction with the arrangement of the first desulfurization unit, the flue gas desulfurization work is completed during the flue gas circulation along the main board.

[0034] (2) The present invention provides an environmentally friendly construction desulfurization device and a construction method thereof. The first water nozzle is arranged so that when the flue gas is inclined upward along the lower side of the main board, the desulfurization slurry can be sprayed in the opposite direction of the flue gas flow direction, thereby preventing the occurrence of spraying dead corners during the flue gas flow process and ensuring the flue gas desulfurization efficiency;

[0035] (3) The present invention provides an environmentally friendly construction desulfurization device and a construction method thereof. The second water nozzle is arranged so that when the flue gas volume is large, that is, when the flue gas inclined upward along the lower side of the main board is thick, the flue gas desulfurization work can still be better completed through the second water nozzle, thereby further ensuring the flue gas desulfurization efficiency.

DETAILED DESCRIPTION

[0049] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0050] Example

[0051] This embodiment first provides an environmentally friendly construction desulfurization device, see Figure 1 and Figure 3 , including a base 1 and several layers of intermediate towers on its upper side, the adjacent intermediate towers are detachably connected, and the upper side of the uppermost intermediate tower is detachably connected with a top tower 6, the intermediate tower includes a vertical cylindrical tower body, a smoke inlet pipe 33 is provided on one side of the tower body of the lowest intermediate tower, the top tower 6 includes a tower cover 61 buckled on the uppermost intermediate tower, a smoke outlet pipe 62 is provided on the upper side of the tower cover 61, the flue gas to be desulfurized can enter the desulfurization device (the above-mentioned environmental protection construction desulfurization device) from the smoke inlet pipe 33, and pass through several layers of intermediate towers from bottom to top, and then under the desulfurization action of several layers of intermediate towers, it is discharged from the smoke outlet pipe 62 of the top tower 6 to complete the desulfurization of the flue gas.

[0052] This embodiment takes the example of the intermediate tower having three layers. Figure 7 and Fig. 9 The intermediate tower includes a first intermediate tower 3, a second intermediate tower 4 and a third intermediate tower 5 which are arranged in sequence from bottom to top. The lower side of the first intermediate tower 3 is connected to the base 1. The tower cover 61 of the top tower 6 is arranged above the third intermediate tower 5. The tower bodies of the first intermediate tower 3, the second intermediate tower 4 and the third intermediate tower 5 are respectively the first tower body 31, the second tower body 41 and the third tower body 51, and each tower body is a square vertical cylinder with a vertical penetration in the middle. The smoke inlet pipe 33 is arranged on one side of the third tower body 51.

[0053] In this embodiment, combined with Figure 2 The base 1 is in the shape of a rectangular parallelepiped, and a pulp pool 11 is provided in the middle of its upper side, and desulfurization slurry is contained in the pulp pool 11. A water pump 2 connected to the inside of the pulp pool 11 is also provided on one side of the base 1. A desulfurization system 32 is provided inside the three tower bodies, and the desulfurization systems 32 inside the three tower bodies are all connected to the water pump 2. The water pump 2 can provide desulfurization slurry to the desulfurization system 32 to complete the desulfurization of the flue gas, and the desulfurized slurry can flow back into the pulp pool 11.

[0054] Furthermore, a replenishing slurry pipe 12 communicating with the interior of the slurry pool 11 is provided on one side of the base 1 , and the replenishing slurry pipe 12 can be used to complete the replenishment, discharge or replacement of the desulfurized slurry.

[0055] In this embodiment, as one of the core technical concepts of the present invention, combined with Figure 4 and Figure 5The desulfurization system 32 includes a main board 321 hingedly connected to the inner wall of the tower body on one side, and a first desulfurization unit 323 is arranged on the other side of the main board 321. The desulfurization system 32 also includes a traction unit 322 drivingly connected to the main board 321, which is configured to drive the main board 321 to rotate. At the same time, the desulfurization systems 32 inside the adjacent intermediate towers are staggered, and the main board 321 can be tilted under the drive of the traction unit 322, and the adjacent first desulfurization units 323 are staggered. At this time, the flue gas entering from the smoke inlet pipe 33 , can move upward in a curved shape under the action of the main board 321, that is, the setting of the main board 321 makes the flue gas, when flowing through the main board 321, concentrate and tilt upward close to the lower side of the main board 321 under the action of circulation, so as to increase the reserved time of the flue gas inside the desulfurization device, and at the same time avoid the setting of the main board 321 to have a greater impact on the fluidity of the flue gas, while having a certain buffering effect on the circulation of the flue gas, cooperate with the setting of the first desulfurization unit 323, and complete the desulfurization of the flue gas during the flow of the flue gas along the main board 321.

[0056] Specifically, the desulfurization system 32 inside the tower body of each intermediate tower is combined with Fig. 9 The smoke inlet pipe 33 is located at the front side of the first tower body 31, the desulfurization system 32 inside the first tower body 31 and the third tower body 51 is located at the rear side of the first tower body 31 and the third tower body 51, and the desulfurization system 32 inside the second tower body 41 is located at the front side of the second tower body 41.

[0057] As for the setting method of the main board 321, the cross-section of the vertical through part in the middle of the tower body is a square structure, and the main board 321 is also a square plate structure, and one side is hinged to the front inner side or rear inner wall of the tower body. To ensure the flow of smoke, the width between the hinged side and the non-hinged side of the main board 321 is smaller than the distance between the front and rear inner walls of the tower body.

[0058] Specifically speaking, the structure of the traction unit 322 includes a traction motor 3221 arranged on the outer wall of the tower body, and the traction motor 3221 is located on the outer wall of the tower body on the hinged side of the main board 321. A traction ear is provided above the main board 321 away from the hinged side. The traction motor 3221 is connected to the traction ear through a traction rope, and through the action of the traction motor 3221, the main board 321 can be pulled to flip under the action of the traction rope.

[0059] As another core technical concept of the present invention, with respect to the structure of the first desulfurization unit 323, combined with Figure 6, which includes a first water pipe 3231 arranged at the lower side of the main board 321 and whose axis is parallel to the rotation axis of the main board 321. The desulfurization system 32 also includes a pipe joint 324 arranged on the tower body. The inner end of the pipe joint 324 is connected to the first water pipe 3231 through a hose (not shown in the figure), and the water pump 2 outside the base 1 is connected to the pipe joint 324. The first water pipe 3231 is linearly arranged with a plurality of first water nozzles 3232 along its length direction. The direction of the water outlet of the first water nozzle 3232 is perpendicular to the axis of the first water pipe 3231. It is parallel to the plate surface of the main board 321 and faces the hinged connection side of the main board 321. The water pump 2 can transport the desulfurization slurry to the first water pipe 3231 through the pipe joint 324 and the hose, and then spray it against the flue gas along the flow direction of the main board 321 through the first water nozzle 3232. Through this arrangement, when the flue gas tilts upward along the lower side of the main board 321, the first water nozzle 3232 located on the lower side of the main board 321 can spray the desulfurization slurry in the opposite direction of the flue gas flow, so as to prevent the occurrence of spraying dead corners during the flue gas circulation process and ensure the flue gas desulfurization efficiency.

[0060] As a further preferred core technical concept, a plurality of second water nozzles 3233 are linearly arranged along the length direction of the first water pipe 3231, and the directions of the water outlets of the plurality of second water nozzles 3233 are perpendicular to the axis of the first water pipe 3231, and form an angle of 40-50 degrees with the direction of the water outlet of the first water nozzle 3232, and are located on the side of the first water nozzle 3232 away from the main board 321. Therefore, when the amount of flue gas is large, that is, when the flue gas inclined upward along the lower side of the main board 321 is thicker, the flue gas desulfurization work can still be better completed through the second water nozzles 3233, thereby further ensuring the flue gas desulfurization efficiency.

[0061] Specifically, in order to prevent interference between the work of the first water nozzle 3232 and the second water nozzle 3233 while ensuring that flue gas desulfurization can be fully carried out, a number of the second water nozzles 3233 and a number of the first water nozzles 3232 are alternately arranged, and the direction of the water outlets of the second water nozzles 3233 is at a 45-degree angle to the direction of the water outlets of the first water nozzle 3232.

[0062] In this embodiment, combined with Figure 4 The main board 321 is also provided with a smoke hole 3211. The interior of the other intermediate towers except the lowest intermediate tower and the side away from the desulfurization system 32 is also provided with a second desulfurization unit 42, that is, the interior of the second tower body 41 and the third tower body 51 is also provided with a second desulfurization unit 42. Figure 8The second desulfurization unit 42 includes a main water pipe 421 inserted into the tower body, and a plurality of rows of second water pipes 422 arranged inside the tower body. The axis of the second water pipe 422 is parallel to the rotation axis of the main board 321. The second water pipe 422 is linearly arranged along its length direction with a plurality of third water nozzles 423 facing downward. Through this arrangement, when the flue gas volume is large, part of the flue gas can directly ascend along the hole and cooperate with the third water nozzles 423 to complete the desulfurization work, and at the same time further prevent the arrangement of the main board 321 from affecting the circulation of the flue gas when the flue gas volume is large.

[0063] In order to ensure the desulfurization effect of the second desulfurization unit 42, the smoke holes 3211 are densely distributed in plurality.

[0064] As a preferred embodiment, the main board 321 is also provided with an adjustment unit 325 capable of adjusting the opening and closing state of the smoke vent 3211, so that when the flue gas flow changes, the amount of flue gas passing through the smoke vent 3211 can be adjusted through the adjustment unit 325, so that the separation flow device can better complete the flue gas desulfurization work at different flue gas volumes.

[0065] Specifically speaking, the structure of the adjustment unit 325 includes an insert plate 3251 that is slidably arranged on the upper surface of the main board 321, and a telescopic driving cylinder 3252 that can drive the insert plate 3251 to slide. The smoke hole 3211 is a long strip structure arranged along the sliding direction of the insert plate 3251, so that the smoke flow through the smoke hole 3211 can be more easily controlled through the action of the telescopic driving cylinder 3252.

[0066] In this embodiment, a dehumidifier is further provided inside the tower cover 61 .

[0067] In this embodiment, as a preferred implementation, the desulfurization device also includes a control system, and the smoke inlet pipe 33 is provided with a first detection unit 34 capable of detecting the flue gas flow rate. The first detection unit 34 and the adjustment unit 325 are both communicatively connected with the control system, and the control system is configured to control the action of the adjustment unit 325 according to the feedback value of the first detection unit 34, and then control the amount of smoke passing through the air vent, so that the amount of smoke passing through the smoke hole 3211 can be automatically controlled according to the smoke intake of the smoke inlet pipe 33, thereby ensuring that the flue gas desulfurization work can be carried out more intelligently and automatically.

[0068] As a further preferred embodiment, the smoke outlet pipe 62 is also provided with a second detection unit 63 capable of detecting the sulfur content in the flue gas. The second detection unit 63 and the traction unit 322 are both communicatively connected to the control system, and the control system is configured to control the action of the traction unit 322 and then control the inclination angle of the main board 321 according to the feedback value of the second detection unit 63, so that the inclination state of the main board 321 can be automatically controlled according to the sulfur content in the flue gas after desulfurization, thereby ensuring the adequacy of flue gas desulfurization and at the same time ensuring that the flue gas desulfurization work can be carried out in a more intelligent and automated manner.

[0069] The present invention also provides a method for constructing the above-mentioned environmentally friendly construction desulfurization device, which specifically comprises the following steps:

[0070] S1: build base 1;

[0071] S1.1: According to the specifications of the tower body, build the base 1 with bricks or stones, and reserve a slurry pool 11, and smooth it with cement slurry;

[0072] S1.2: After the cement slurry on the base 1 is cured, a waterproof and alkali-resistant coating is applied inside the slurry pool 11;

[0073] S1.3: Install a water pump 2 on the outside of the base 1;

[0074] S1.4: injecting desulfurization slurry into the slurry pool 11 through the replenishing slurry pipe 12 (of course, step S1.4 can also be performed after the desulfurization device is fully assembled, and no unnecessary restrictions are made here);

[0075] S2: Install the intermediate tower;

[0076] S2.1: Based on a plurality of tower bodies, the desulfurization system 32 is assembled thereon, and the main board 321 is adjusted to tilt upward away from the side of the hinged connection by the traction motor 3221;

[0077] It should be noted that the height of the main board 321 away from the hinged connection side does not exceed the upper edge of the tower body, so as to ensure that the installation of the middle tower can be more convenient and avoid the interference of the setting of the desulfurization system 32 on the assembly of the middle tower, and the inclination angles of the main boards 321 inside the tower bodies are the same, so that the inclination angle of the main board 321 can be adjusted more conveniently after the assembly is completed;

[0078] The specific steps include:

[0079] S2.1.1: Install the first desulfurization unit 323 and the adjustment unit 325 on the main board 321;

[0080] S2.1.2: Hinging the main board 321 inside the box;

[0081] S2.1.3: Install the traction unit 322 and connect it to the main board 321 through the traction rope;

[0082] S2.1.4: Adjust the inclination angle of the main board 321 by the traction motor 3221;

[0083] S2.1.5: Install the pipe connector 324 and the hose;

[0084] S2.2: assemble the assembled intermediate towers in sequence from bottom to top;

[0085] S3: Install the top tower 6;

[0086] S4: adjust the main board 321;

[0087] The inclination angle of the main board 321 inside each tower body is adjusted by the traction unit 322, so that the inclination angle of the lower main board 321 of the middle tower of two adjacent layers is greater than the inclination angle of the upper main board 321, so that the flue gas entering from the smoke inlet pipe 33 can have better fluidity, and prevent the smoke inlet from being blocked due to the position of the smoke inlet pipe 33. At the same time, the bottom desulfurization system 32 completes the initial desulfurization work, and in the process of the flue gas ascending, the buffering effect of the flue gas is gradually increased, and finally the flue gas desulfurization work is carried out step by step, so as to ensure that the flue gas desulfurization work can be more sufficient;

[0088] It should be noted that the inclination angle of any of the main boards 321 is in the range of 15-50 degrees, which ensures that the main board 321 has a better guiding effect on the smoke while preventing the setting of the main board 321 from having a significant impact on the smoke flowability;

[0089] As a preferred embodiment, in order to ensure the desulfurization efficiency and the extended flowability, the flue gas can better complete the desulfurization work layer by layer during the upward process, and the inclination ratio of the adjacent upper and lower main boards 321 relative to the horizontal plane is not less than 1:2 and not more than 3:4;

[0090] S5: Connect the water pump 2 and the pipe joint 324.
