[0028] Reference below Figure 1-Figure 3 The containerized desulfurization equipment according to the embodiment of the utility model is described.

[0029] like Figure 1-Figure 3 As shown, the containerized desulfurization equipment includes a cabinet-type box 100, and the desulfurization equipment is installed in the cabinet-type box 100. The specifications of the cabinet-type box 100 meet the national standard "External Dimensions and Rated Mass of Containers" (GB 1413-2008). It is convenient for transportation by various transportation routes, effectively solves the problems of transportation efficiency and transportation risks of tower-type desulfurization equipment, and facilitates the rapid commissioning of desulfurization equipment, thereby improving work efficiency.

[0030] Specifically, the cabinet box 100 includes a reaction area 110 and a work area 120, and the work area 120 is located on one side of the reaction area 110. The staff can observe the working conditions of each area in the reaction area 110 when they are active in the work area 120. The reaction area 110 includes a spray part 200, an acid-base adjustment part 300, a sludge part 400 and a sedimentation part 500. Specifically, the spray part 200 is arranged on one side of the reaction area 110, and the spray part 200 and the air inlet (not shown in the drawings) of the reaction area 110 are connected to the external waste gas, and the air inlet is used to input the waste gas to be treated. When the cabinet box 100 is positioned and installed at the designated position, the air inlet is connected to the production equipment through a pipeline, so that the waste gas generated by the production equipment is passed from the air inlet into the spray part 200, and the waste gas is mixed with the liquid in the spray part 200. The structure of the spray part 200 is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.

[0031] The acid-base regulating section 300 is arranged on one side of the spray section 200 and is connected to the spray section 200. The waste gas mixed liquid of the spray section 200 is passed into the acid-base regulating section 300. The pH value of the waste liquid is adjusted in the acid-base regulating section 300 to achieve acid-base neutralization. The sludge section 400 is arranged on one side of the acid-base regulating section 300 and is connected to the acid-base regulating section 300. The sludge section 400 and the acid-base regulating section 300 are arranged in a square layout. The waste liquid with adjusted pH value is passed into the sludge section 400. The sludge section 400 is arranged on one side of the acid-base regulating section 300 and is connected to the acid-base regulating section 300. The sludge section 400 and the acid-base regulating section 300 are arranged in a square layout to reasonably utilize the space in the cabinet box 100. In the sludge section 400, the suspended solid particles in the waste liquid are settled to the bottom of the sludge section 400, and finally the waste liquid is passed into the sedimentation section 500. The sedimentation section 500 is arranged side by side on one side of the sludge section 400. One end of the sedimentation section 500 is connected to the sludge section 400, and the other end is connected to the discharge port of the reaction zone 110 (not shown in the drawings). The discharge port is used to output the treated waste liquid. According to the composition of the waste liquid, the corresponding chemical liquid is added to react with the waste liquid to form a chemical precipitate, and then discharged to the outside through the discharge port.

[0032] The spraying section 200, the acid-base adjustment section 300, the sludge section 400 and the sedimentation section 500 are arranged in a horizontal direction, and are respectively provided with a maintenance port 130 connected to the working area 120. Specifically, each area of ​​the reaction area 110 is arranged on the same horizontal plane, and is respectively equipped with a maintenance port 130. The staff does not need to climb to a high place for later maintenance, but only needs to be at a certain height to check each area or clean the bottom of the area through the maintenance port 130.

[0033] The container-type desulfurization equipment of this embodiment realizes the low-position setting of the desulfurization structure through the horizontal layout, effectively reducing the safety hazards, and the horizontal setting of the reaction zone 110 enables the exhaust gas to obtain a longer reaction path after passing into the reaction zone 110, so that the waste liquid can fully react, and the reaction efficiency is higher than that of the tower structure. The cabinet-type box 100 makes the transportation of the desulfurization equipment more convenient and meets different transportation forms.

[0034] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the acid-base adjustment part 300 includes three groups of adjustment tanks 310, which are arranged in an L shape and connected in sequence. The adjustment tank 310 close to the working area 120 is connected to the spray part 200, and the terminal adjustment tank 310 is connected to the sludge part 400.

[0035] Specifically, in order to extend the reaction path of the waste liquid, the three groups of regulating tanks 310 adopt an L-shaped layout to extend the total path of the acid-base regulating part 300. Each regulating tank 310 can individually adjust the pH value of the waste liquid to make the waste liquid reach a preset pH value.

[0036] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the fluid channel 311 between each regulating tank 310 is arranged at the top area and a stirring mounting seat (not shown in the drawings) is arranged around the fluid channel 311, and the stirring mounting seat is used to install a stirring mechanism (not shown in the drawings). Specifically, the stirring mounting seat is used to install a stirring mechanism, and the stirring mechanism can make the waste liquid in the corresponding regulating tank 310 and the regulating liquid mix fully, and the reaction is more complete.

[0037] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the sedimentation section 500 includes at least one group of sedimentation tanks 510, which are connected in sequence and arranged side by side on one side of the sludge section 400. The sedimentation tank 510 close to the sludge section 400 is connected to the sludge section 400, and the terminal sedimentation tank 510 is connected to the discharge port.

[0038] In this embodiment, there are four groups of sedimentation tanks 510. Specifically, the number and width of the sedimentation tanks 510 are matched according to the length of the cabinet 100. In other embodiments, the sedimentation tanks 510 can be two or three groups. When there is only one group of sedimentation tanks 510, all reaction liquids are put into the same sedimentation tank 510.

[0039] In some embodiments of the present invention, Figure 1 As shown, the vertical projection profile of the sedimentation tank 510 is the same as the vertical projection profile of the spray section 200. Specifically, the length of the sedimentation tank 510 is consistent with the length of the spray section 200, ensuring that the side wall of the reaction area 110 close to the working area 120 is flat, ensuring the activity space of the working area 120.

[0040] In some embodiments of the present invention, the tops of the acid-base adjustment section 300, the sludge section 400, and the precipitation section 500 are respectively provided with covers (not shown in the drawings), and the covers are used to close the corresponding top openings. Specifically, the top of the reaction zone 110 is closed by the cover during operation, and the staff opens the cover to observe and maintain the interior in the maintenance state.

[0041] In some embodiments of the present invention, the ratio of the depth of the reaction zone 110 to the height of the cabinet 100 is 0.5 to 0.6, ensuring that there is enough distance between the top of the cabinet 100 and the top surface of the reaction zone 110 for workers to enter and exit the reaction zone 110 for maintenance.

[0042] In some embodiments of the present invention, Figure 1As shown, a climbing structure 160 is provided in the working area 120, and the climbing structure 160 is provided on one side of the reaction area 110. Specifically, the climbing structure 160 can be any one of a telescopic ladder, a straight ladder or an inclined ladder.
