Description

Technical Field

[0001] This utility model relates to the technical field of low-temperature SCR denitrification catalyst regeneration device, and in particular to a low-temperature SCR denitrification catalyst regeneration device. Background Technology

[0002] The low-temperature SCR denitrification catalyst regeneration unit is a specialized equipment system for restoring the activity of deactivated catalysts used in low-temperature selective catalytic reduction denitrification processes. Its core function is to remove contaminants and blockages that cause catalyst deactivation through specific physicochemical treatment processes, replenishing or restoring active components, and restoring the catalyst performance to a level as close as possible to that of a new catalyst.

[0003] The mechanism of the low-temperature SCR denitrification catalyst regeneration device can be referenced from the utility model disclosed in authorization announcement number "CN222918703U" as "An In-situ Regeneration Device for SCR Denitrification Catalyst". This device includes an auxiliary mechanism, a support mechanism, a control panel B, a timer, and a belt conveyor. The timer is set to the required drying time. When the power is turned on, two sets of dryers are started. The two dryers generate heat to dry the items on the top surface of the wide plate. When the timer reaches the preset time, it outputs a signal to the control panel B. Upon receiving the signal, the control panel B controls the hydraulic cylinder to lift the wide plate and flip it to the front, thus transporting the dried items onto the belt conveyor. The device utilizes a sliding rail, a height adjustment mechanism, an infrared sensor, and a receiver. With the clamping mechanism in place, the item is positioned directly below the infrared sensor. Power is connected, and the electric telescopic rod is activated. The electric telescopic rod moves the receiver and clamping mechanism downwards until the receiver is directly in front of the infrared sensor. The infrared sensor transmits a signal to control panel A, which then controls the hydraulic rod to tighten the two sets of clamps, thus securing the item. The item moves downwards with the clamping mechanism until it is immersed in the acid-alkali chemical soaking tank. Furthermore, the sliding track has a certain sliding performance, which, together with the height adjustment mechanism, facilitates the sequential placement of the item into the active solution soaking tank and the reinforcing agent soaking tank for regeneration treatment. This solves the problem of manually removing materials from the dryer and placing them in designated areas, and the increased risk of operators coming into contact with hazardous substances during manual operation.

[0004] The aforementioned drain pipe was not filtered, and impurities in the solution may clog the drain pipe when the solution is discharged. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-temperature SCR denitrification catalyst regeneration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 The low-temperature SCR denitrification catalyst regeneration device includes a regeneration device body 1, which includes a tank 11. Three main drain pipes 12 are evenly spaced on one side of the bottom of the tank 11, and a filter assembly 2 is provided on one side of the main drain pipes 12. The filter assembly 2 includes a filter box 21, which has a filter cavity. A reserved groove communicating with the filter cavity is provided on one side of the filter box 21. A filter screen 24 is inserted into the reserved groove. A drain assembly 23 is screwed to the side of the filter box 21 adjacent to the filter screen 24. A sealing cap 4 is screwed to the end of the drain assembly 23. By setting the sealing cap 4, the drain assembly 23 is sealed when no drainage is required to prevent solution leakage.

[0023] It is worth noting that the specific structure, connection method and working principle of the regeneration device body 1, the pool body 11 and the main drain pipe 12 are all based on the utility model disclosed in the authorization announcement number "CN222918703U" as "an in-situ regeneration device for SCR denitrification catalyst", so they will not be described in detail here.

[0024] A movable retaining ring 22 is movably embedded inside the filter housing 21, and extension rods are symmetrically installed on both sides of the movable retaining ring 22. One side of the extension rod extends into the filter cavity, and a scraper body 222 is installed between the two extension rods. The working end face of the scraper body 222 contacts the inner surface of the filter screen 24, and the rotation of the movable retaining ring 22 drives the scraper body 222 to scrape away impurities from the surface of the filter screen 24. At the same time, a handle 221 is provided on one side of the outer wall of the movable retaining ring 22.

[0025] Furthermore, multiple handle blocks are installed in a circular array at equal intervals on one side of the filter screen 24. The handle blocks make the filter screen 24 easy to remove for cleaning and maintenance.

[0026] Meanwhile, the drainage assembly 23 includes a mounting ring 231. A pressure ring is installed on one side of the mounting ring 231 at a reserved groove, and a clearance groove is provided inside the pressure ring at the handle block. The outer wall of the pressure ring is provided with an external thread. The pressure ring presses against the edge of the filter screen 24. Specifically, when the drainage assembly is tightened, the pressure ring on the mounting ring 231 will press against the edge of the filter screen 24. This forms a second seal, ensuring that sewage can only flow out after being filtered through the filter screen, preventing unfiltered sewage from short-circuiting and leaking from the edge of the screen and the gap between the housing.

[0027] Meanwhile, the inner wall of the reserved groove is provided with a first internal thread at the first external thread, and the first internal thread is threadedly connected to the first external thread.

[0028] Furthermore, an auxiliary drain pipe 232 is installed on one side of the mounting ring 231, and a second external thread is provided on the outer wall of the auxiliary drain pipe 232 away from the mounting ring 231. A second thread is also provided inside the sealing cover 4 at the location of the second external thread, and the second internal thread is threadedly connected to the second external thread. A sealing ring gasket is fixedly embedded inside the mounting ring 231.

[0029] Furthermore, a water inlet pipe is provided on the side of the filter housing 21 away from the drain assembly 23, and the water inlet pipe is connected to the main drain pipe 12 through multiple flange assemblies 3.

[0030] It is worth noting that multiple sealing gaskets are fixedly embedded at equal intervals on both sides of the outer wall of the movable ring 22, and the end face of the sealing gasket is flush with the end face of the movable ring 22.

[0031] In this embodiment, larger solid impurities or precipitates in the solution are intercepted during the drainage process by the filter screen 24 in the filter assembly 2.

[0032] At the same time, when the movable ring 22 on the handle 221 is rotated by hand, the scraper body will scrape off the impurities attached to the inner surface of the filter screen, preventing the filter screen plate 24 from being blocked by impurities.

[0033] Furthermore, when it is necessary to disassemble, maintain, and clean the filter screen 24, simply loosen the threads of the drain assembly 23 and grasp the handle to remove the filter screen 24. It is worth noting that the filter screen 24 is made of acid and alkali resistant stainless steel.

[0034] In this invention, the detachable filter screen 24 intercepts larger solid impurities in the solution during the drainage process. At the same time, the movable insert ring 22 and the scraper body scrape off impurities attached to the inner surface of the filter screen, preventing the filter screen 24 from being blocked by impurities.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
