Description

TECHNICAL FIELD

[0001] The utility model relates to industrial gas purification treatment technical field, especially relate to a continuous gas purification equipment. BACKGROUND

[0002] Industrial flue gas is the gaseous product of fuel combustion in the industrial production process of enterprises. It usually contains a large amount of solid dust and toxic gases and other harmful substances, especially carbon monoxide gas which has been concerned in recent years. In conventional carbon monoxide treatment equipment and other types of flue gas purification equipment, a fixed bed filler structure is adopted. For example, CN202311805432.5 discloses a flue gas treatment device utilizing the carbon monoxide heat value in sintering flue gas, and CN202021463211.6 discloses a sintering flue gas carbon monoxide and nitrogen oxide combined removal device. In these technologies, the purification filler is laid on the fixed filter plate to control the flue gas to pass through the filler and the filter plate to achieve purification, which has the defects of low treatment efficiency and inconvenient filler replacement.

[0003] The applicant has applied for a patent with the application number 2024213766018, which is a mobile bed type sintering flue gas treatment equipment. In this equipment, a denitration catalytic fixed bed is arranged at the upper part of the device, and a mobile bed for carbon monoxide purification is arranged below. The use of a mobile bed improves the purification efficiency of carbon monoxide and facilitates the replacement of carbon monoxide catalyst filler. However, this equipment still has the following defects: 1. The denitration treatment part is still a fixed bed in the same equipment, which still has the defect of inconvenient filler replacement. 2. The carbon monoxide purification uses a horizontally arranged mobile bed structure, but the horizontal space of the equipment is limited, which affects the improvement of the treatment efficiency. 3. The horizontally arranged mobile bed has a large difference in activity between the head and tail of the filler, but the flue gas pressure and flue gas flow are the same, which leads to a decrease in the treatment effect and efficiency of the filler, and the treatment effect of the flue gas passing through the tail of the mobile bed is poor.

[0004] To solve the above problems, the applicant considers changing the direction of the filler movement in the equipment to vertical, allowing the gas to be purified to enter from the top of the equipment and then pass horizontally through the vertically moving filler to achieve purification, and then discharge from the bottom of the equipment. In this way, the upper active filler bears a stronger gas pressure, and the lower active filler bears a lower gas pressure. The activity of the filler at different positions and the corresponding gas pressure are matched, which can better improve the treatment effect and efficiency of the filler.

[0005] Therefore, how to design a specific equipment to realize the adjustment of the above purification method to improve the purification effect of the filler has become a problem to be considered and solved by the applicant. UTILITY MODEL CONTENTS

[0006] In view of the above prior art, the technical problem to be solved by the utility model is: how to provide a continuous gas purification equipment which can conveniently realize packing replacement and better improve packing purification efficiency and effect.

[0007] In order to solve the above technical problem, the utility model adopts the following technical scheme:

[0008] A continuous gas purification equipment, comprising a shell, characterized in that the shell has vertically arranged and horizontally spaced purification zones, each pair of purification zones is formed by four vertically arranged and horizontally spaced air passing partitions, an upper partition is horizontally fixed between the upper ends of the two air passing partitions in each pair of purification zones, the upper ends of the purification zones on the two sides of the upper partition are designed as open, a lower partition is horizontally fixed between the lower ends of the two air passing partitions on the outer side of each pair of purification zones and the shell or the air passing partitions on the outer side of other pairs of purification zones, a discharging device is arranged at the outlet below each purification zone, a feeding device is further arranged on the upper part of the shell and connected with the upper end openings of each purification zone, a gas inlet is formed in the top of the shell and communicated with the air passing spaces on the outer sides of each pair of purification zones, and a gas outlet is formed in the bottom of the shell and communicated with the air passing spaces on the inner sides of each pair of purification zones.

[0009] In this way, when the equipment is used, the packing is fed into each purification zone from the feeding device, the gas to be purified is fed into the air passing spaces on the outer sides of each pair of purification zones from the gas inlet in the top of the shell, then horizontally passes through the corresponding air passing partitions to enter the purification zones and react with the packing, then passes through the air passing partitions on the inner sides to enter the air passing spaces on the inner sides of each pair of purification zones, and then flows out from the gas outlet in the bottom of the shell. In this way, the on-line replacement operation of the packing can be conveniently realized, and the continuous feeding of the packing can also be realized. Meanwhile, the contact area of the packing and the gas is increased, and the flow direction of the packing is consistent with the pressure reduction direction of the gas, so that the activity of the packing and the flux of the gas are matched, thereby better improving the treatment effect and efficiency. The equipment is particularly suitable for the purification treatment of industrial flue gas and can also be used for the purification treatment of other industrial gases which need to be purified.

[0010] Further, the feeding device comprises a feeding hopper located on one side of the upper part of the shell, the lower end of the feeding hopper penetrates into the shell and is arranged opposite to one end of the feeding platform in the length direction, the feeding platform is horizontally fixed in the inner cavity of the shell and located above each pair of purification zones in the width direction, and a scraping mechanism is arranged on the feeding platform and used for scraping the material to the purification zones on the two sides.

[0011] Thus, the feeding platform is arranged above the upper partition plate at the upper end of each pair of purification areas, the filler is fed into the feeding platform through the hopper, and then the material is scraped by the scraping mechanism to the two purification areas, so as to realize the vertical feeding from the feeding hopper to the purification area and ensure the continuous processing effect of the filler.

[0012] Further, the sealing feeding mechanism is arranged at the outlet of the lower end of the feeding hopper, the sealing feeding mechanism comprises a horizontally arranged feeding space, the feeding space is communicated with the feeding hopper at the upper side outside, and the outlet at the lower side inside is designed to face the end of the feeding platform, a feeding shaft is horizontally arranged at the middle position of the feeding space, a plurality of rotating scrapers are uniformly arranged on the feeding shaft, the rotating scrapers are arranged along the axis direction of the feeding shaft and are arranged close to or in contact with the inner wall of the feeding space at the outside, and one end of the feeding shaft is in transmission connection with the feeding control motor.

[0013] Thus, the filler flows from the feeding hopper to the feeding space, and then the feeding shaft is driven to rotate under the action of the feeding control motor, the filler is scraped downward by the rotation of the rotating scraper. The feeding control can be realized while ensuring the sealing effect, and the feeding rate can be adjusted to avoid gas overflow from the feeding device.

[0014] Further, the scraping mechanism comprises two horizontally arranged annular chains at the two sides of the feeding platform, the upper half of each of the two annular chains is horizontally arranged along the edge position of the upper surface of the feeding platform, the two ends of the two annular chains are respectively arranged on a pair of vertically arranged chain wheels at the two sides of the two ends of the feeding platform, the chain wheels are in transmission connection with the scraping motor, and a plurality of vertically arranged scrapers are transversely and fixedly connected between the two annular chains, the lower surface of the scraper of the upper half of the annular chain is arranged close to the upper surface of the feeding platform (a spacing space is left between the upper cover plate and the feeding platform for the movement of the scraper below the annular chain).

[0015] Thus, the chain wheel and the chain are driven to circulate by the scraping motor, and then the scraper is driven to move along the feeding end to the other end of the upper surface of the feeding platform, so that the filler falling on the feeding platform is scraped to the corresponding purification area. Therefore, the continuous transfer of the filler from the feeding device to the purification area can be conveniently and quickly realized, and the continuous processing of the filler is realized.

[0016] Further, the scrapers are equidistantly distributed between adjacent scrapers. The uniform and continuous transfer of the filler is better ensured.

[0017] Further, any two adjacent scrapers are symmetrically arranged in opposite directions in a herringbone shape.

[0018] In this way, the two adjacent scrapers are arranged on the front and back of the feeding platform, and the inclined scraper can quickly scrape the material to the side of the feeding platform. The inclination refers to the inclined (non-vertical) arrangement relative to the chain.

[0019] Further, the upper end edge of the scraper on the upper surface of the feeding platform has a folding portion inclined upwardly rearwardly, and the horizontal projection of the upper side edge of the folding portion is perpendicular to the chain (rearwardly upwardly refers to the rearwardly upwardly opposite to the forward direction).

[0020] In this way, after the scraper is arranged in the shape of a splayed, although the size of the area between every two adjacent scrapers is the same, due to the certain width of the feeding, when the falling position of the filling is eccentric (i.e. the filling falls on the feeding platform and is not evenly distributed along the middle position), the splayed scraper will increase the uneven falling effect, i.e. more material will be scraped to the eccentric side (because more material falls into the splayed area on the eccentric side). Therefore, after the above improvement, since the folding portion on the upper end of the scraper extends rearwardly upwardly to the position perpendicular to the chain, the material falling between the two adjacent scrapers is evenly distributed along the rectangular area of the same size. Therefore, even if the falling of the filling on the feeding platform is eccentric, the amount of material scraped to the two side purification areas is balanced, which better ensures the stability of the overall equipment operation.

[0021] Further, the lower end of the scraper on the upper surface of the feeding platform is fixed on a horizontally arranged connecting plate, the lower surface of the connecting plate is arranged close to or in contact with the feeding platform, and the two ends of the connecting plate have a vertical connecting portion and are fixed on the chain by means of bolts passing through the connecting portion.

[0022] In this way, the scraper is fixedly connected with the chain through the connecting plate, which is convenient for installation and setting. At the same time, the connecting plate widens the thickness of the scraping position where the scraper contacts the feeding platform, which can better prevent wear and tear and better ensure the scraping effect.

[0023] Further, it further comprises a material level monitoring device, the material level monitoring device comprises a material level meter for feeding monitoring, and further comprises a detection bin, the detection bin is arranged at a position below the shell at the front end of the feeding platform, the upper end of the detection bin is sealingly connected with the inner cavity of the shell and is communicated with the upper end of the purification area through a horizontal communication space, and the material level meter for feeding monitoring is arranged in the detection bin.

[0024] Thus, the upper port in the purification area needs to be provided with a material level meter for monitoring the filling amount of the filler, and after detecting that the purification area is filled to the brim, feedback control is needed to reduce the feeding rate to ensure the stable and normal flow of the filler in the device. However, the purification area has a large gas pressure and a high temperature, and there is continuous impact of the filler falling, and the working environment is harsh, so that the feeding monitoring material level meter detection is often unstable and has a short service life. Therefore, the applicant creatively improves the material level meter device, and a detection bin connected with the purification area is arranged below the shell at the front end of the feeding platform, so that when the purification area is filled to the brim, the filler will gradually overflow and fall into the detection bin, and then the feeding monitoring material level meter arranged in the detection bin can determine whether the filler in the purification area is filled to the brim, and then feedback to the control center to adjust and control the feeding rate of the feeding device or directly alarm. In this way, because the pressure and temperature in the detection bin are far lower than those in the purification area, and the filler does not need to be subjected to long-term impact of falling, the stability and reliability of the material level detection can be better ensured, and the service life of the feeding monitoring material level meter is prolonged.

[0025] Further, the shell is outwardly protruded at a position opposite to the front end of the feeding platform to form a protruding portion, the front end of the feeding platform and the annular chains on both sides thereof are extended and installed in the protruding portion, and a funnel is arranged below the protruding portion and communicates with the upper end of the detection bin.

[0026] In this way, when the communication space between the upper end of the detection bin and the upper end of the purification area is blocked, the filler in the purification area rises and accumulates to the position of the feeding platform, and at this time, the filler on the feeding platform cannot fall to both sides and is directly driven by the scraper to the front end to fall into the detection bin, and is detected by the feeding monitoring material level meter and feedback control signal. Therefore, the reliability of the material level monitoring can be better ensured.

[0027] Further, a detection bin outlet is arranged at the lower end of the detection bin, and a detection bin outlet valve is installed at the detection bin outlet.

[0028] In this way, the filler in the detection bin can be conveniently discharged.

[0029] Further, an installation opening is formed in the side surface of the detection bin, a detection flange is abutted and arranged at the installation opening, and the feeding monitoring material level meter is transversely installed on the detection flange.

[0030] In this way, the feeding monitoring material level meter can be more conveniently installed and removed.

[0031] Further, at least two feeding monitoring material level meters are installed in the detection bin along the height direction.

[0032] In this way, the feedback signal of the lower feed monitoring level gauge can be used to control the feed device to reduce the feed rate, and the feedback signal of the upper feed monitoring level gauge can be used to stop the feed device from feeding, so that the control effect is better and the system is stable.

[0033] Further, the upper end of the detection bin is further provided with a maintenance aperture, and a cover is fixedly installed at the maintenance aperture to realize sealing.

[0034] Further, the discharge device comprises a discharge butterfly valve installed at the lower end outlet of the purification area, and a horizontal conveying device horizontally arranged below the lower end outlet of the purification area.

[0035] In this way, after the filler is deactivated after reacting in the purification area, the discharge butterfly valve is controlled to be opened, the deactivated filler falls from the lower end outlet of the purification area to the horizontal conveying device below, and then is conveyed by the horizontal conveying device to the front to fall into the discharge hopper, and then is further dropped into the discharge bin, and when the discharge bin is full, the discharge valve can be opened to discharge the filler. In this way, the deactivated filler is smoothly discharged, and the existence of the discharge bin enables the filler in the purification area to be processed in batch mode or in continuous mode, so that the operation flexibility is greatly improved.

[0036] Further, the horizontal conveying device is a chain plate conveyor. In this way, the structure is simple and reliable. Of course, other horizontal conveying devices such as a belt conveyor can also be used.

[0037] Further, the discharge butterfly valve comprises a discharge shaft horizontally arranged at the middle position of the outlet along the length direction of the lower end outlet of the purification area, one end of the discharge shaft is connected with a discharge motor through the shell, and discharge baffles are further installed on both sides of the discharge shaft along the axial direction, and the discharge baffles can be attached to the inner wall of the lower end outlet of the purification area when the discharge baffles rotate horizontally.

[0038] In this way, the discharge motor is only needed to control the rotation of the discharge shaft, so as to adjust the gap between the discharge baffles and the inner wall of the lower end outlet of the purification area, and then the discharge rate and the closing control are realized.

[0039] Further, the lower end of the discharge hopper is further provided with a partition valve.

[0040] In this way, when the discharge bin is discharged, the partition valve can be closed first, and the deactivated filler is temporarily stored in the discharge hopper, and then the partition valve is opened after the discharge bin is discharged and the discharge valve is closed. In this way, the safety is better improved.

[0041] Furthermore, a material level meter is installed at the upper end of the discharge bin, which can remind you to discharge the material in time when the deactivated filler is full.

[0042] In summary, the utility model has the advantages of facilitating online filling and replacement of fillers and better improving the purification efficiency and effect of fillers. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0050] Best embodiment: A continuous gas purification device, such as Figures 1-6 As shown, the continuous gas purification equipment includes an outer shell 1, and the inner shell 1 has purification areas 2 arranged vertically and spaced horizontally in pairs. Each pair of purification areas 2 is composed of four vertically arranged and horizontally spaced gas baffles 3. The gas baffles are baffles with evenly distributed gas holes for gas to pass through but fillers cannot pass through. An upper baffle 4 is fixed horizontally between the upper ends of the two gas baffles in each pair of purification areas 2. The upper ends of the purification areas on both sides of the upper baffle 4 are open. A lower baffle 5 is also fixed horizontally between the lower ends of the two gas baffles outside each pair of purification areas 2 and the outer shell or other pairs of purification areas. A discharge device is provided at the outlet below each purification area, and a feeding device is also provided on the upper part of the shell to connect with the opening at the upper end of each purification area. A gas inlet 6 is provided at the top of the shell to communicate with the gas space outside each pair of purification areas, and a gas outlet 7 is provided at the bottom to communicate with the gas space inside each pair of purification areas. Figures 1-6The continuous gas purification device shown only has one pair of purification zones. Of course, when the method is implemented, a continuous gas purification device with multiple pairs of purification zones can also be used.

[0051] In this way, when the device is in use, the filler flows from the feeding device into each purification zone, the gas to be purified flows into the outer gas inlet at the top of the shell, then enters the gas space outside each pair of purification zones, and then horizontally passes through the corresponding gas separation plate to enter the inside of the purification zone and contact the filler for reaction, and then passes through the inside gas separation plate to enter the gas space inside each pair of purification zones, and then flows out from the gas outlet at the bottom of the shell. In this way, the on-line replacement operation of the filler can be easily realized, and the filler can also be continuously filled. At the same time, the contact area between the filler and the gas is increased, and the flow direction of the filler is consistent with the pressure drop direction of the gas, so that the activity of the filler and the size of the gas flux are matched, thereby better improving the treatment effect and efficiency.

[0052] The feeding device includes a feeding hopper 8 located on one side of the upper part of the shell, the lower end of the feeding hopper 8 penetrates into the shell and is arranged opposite to one end of the length direction of the feeding platform 9, the feeding platform 9 is horizontally fixed in the inner cavity of the shell and the two sides in the width direction are located above the pair of purification zones 2, and a scraping mechanism is arranged on the feeding platform 9 to scrape the material to the two purification zones.

[0053] In this way, the feeding platform is arranged above the upper partition plate at the upper end of each pair of purification zones, the filler enters the feeding platform through the hopper, and then the material is scraped to the two purification zones by the scraping mechanism, thereby completing the moving feeding from the feeding hopper to the vertical purification zone and ensuring the continuous treatment effect of the filler.

[0054] The lower end outlet of the feeding hopper 8 is provided with a sealing feeding mechanism 10, the sealing feeding mechanism 10 includes a square feeding space arranged horizontally, the feeding space is communicated with the feeding hopper on the upper side outside, the outlet on the lower side inside is designed to be opposite to the end of the feeding platform, a feeding shaft is arranged horizontally at the middle position of the feeding space, a plurality of rotating scrapers are uniformly installed on the feeding shaft, the rotating scrapers are arranged along the axis direction of the feeding shaft and are arranged close to or in contact with the inner wall of the feeding space on the outside, and one end of the feeding shaft is in transmission connection with a feeding control motor.

[0055] In this way, after the filler flows from the feeding hopper to the feeding space, the feeding shaft is driven to rotate under the action of the feeding control motor, and the filler is scraped out downward by relying on the rotation of the rotating scraper. The feeding control can be realized while ensuring the sealing effect, and the feeding rate can be adjusted to avoid the overflow of the gas from the feeding device.

[0056] The scraping mechanism comprises two annular chains 11 arranged horizontally on both sides of the feeding platform, upper halves of the two annular chains 11 are arranged horizontally along edges of upper surfaces of the feeding platform 9, two ends of the two annular chains 11 are respectively arranged on a pair of chain wheels 12 arranged vertically on both sides of the feeding platform, the chain wheels 12 are in driving connection with a scraping motor 13, a plurality of vertically arranged scrapers 14 are transversely and fixedly connected between the two annular chains, and lower surfaces of the scrapers of the upper halves of the annular chains 11 are arranged close to the upper surface of the feeding platform (a spacing space is left between the upper cover plate and the feeding platform for movement of the scrapers below the annular chains).

[0057] In this way, the scrapers are moved along the upper surface of the feeding platform from the feeding end to the other end by the circular movement of the chain wheels and the chains driven by the scraping motor, so that the fillings falling on the feeding platform are scraped to the corresponding purification areas on both sides. Therefore, the continuous transfer of the fillings from the feeding device to the purification area can be conveniently and quickly completed, and the continuous treatment of the fillings is realized.

[0058] The scrapers are equidistantly arranged between adjacent scrapers 14, which can better ensure the uniform and continuous transfer of the fillings.

[0059] The scrapers are symmetrically arranged in a figure-eight shape in opposite directions.

[0060] In this way, the two adjacent scrapers can scrape the fillings to different sides of the feeding platform, respectively. The scrapers arranged in an inclined manner can more quickly scrape the fillings to the sides of the feeding platform. The inclination refers to an inclined (non-vertical) arrangement relative to the chain.

[0061] The upper end edge of the scraper 14 on the upper surface of the feeding platform has a folding portion 15 inclined upward and backward, and the horizontal projection of the upper side edge of the folding portion 15 is perpendicular to the chain (the upward and backward refers to the opposite direction of the forward direction).

[0062] Thus, since the scrapers are arranged in a splayed manner, although the areas between every two adjacent scrapers are the same, due to the certain width of the feed material, when the falling position of the fillings is eccentric (i.e. the fillings are not evenly distributed along the middle position when falling onto the feed platform), the splayed scrapers will increase the uneven falling effect, i.e. more fillings will be scraped to the eccentric side (because more fillings will fall into the splayed area on the eccentric side). Therefore, after the above improvement, since the upper end of the scraper is provided with a folding part extending upwardly and rearwardly to a position perpendicular to the chain, the fillings falling between every two adjacent scrapers are evenly distributed along the same area of the rectangular area, so that even when the fillings falling onto the feed platform are eccentric, the amount of fillings falling between every two adjacent scrapers is still the same. Therefore, the above structure can ensure that when the fillings falling onto the feed platform are eccentric, the amount of fillings scraped to the two purification areas is balanced, which better ensures the stability of the overall equipment operation.

[0063] The lower end of the scraper 14 on the upper surface of the feed platform is fixed on a horizontally arranged connecting plate 16, the lower surface of the connecting plate 16 is arranged close to or in contact with the feed platform, and the two ends of the connecting plate 16 have a vertical connecting part and are fixed on the chain by means of bolts passing through the connecting part.

[0064] Thus, the scraper is fixedly connected with the chain through the connecting plate, which is convenient for installation and setting, and at the same time, the connecting plate widens the thickness of the scraping position of the scraper and the feed platform, which can better prevent wear and tear and better ensure the scraping effect.

[0065] The material level monitoring device includes a material level meter 18 for feed monitoring, and a detection bin 17 arranged below the housing at the front end of the feed platform, and the upper port of the detection bin 17 is sealingly connected with the inner cavity of the housing and communicates with the upper end of the purification area through a horizontal communication space. The material level meter 18 for feed monitoring is arranged in the detection bin 17.

[0066] The reason is that the upper port in the purification area needs to be provided with a material level meter for monitoring the filling amount of the filler, and after detecting that the purification area is filled, feedback control is needed to reduce the feeding rate to ensure the stable and normal flow of the filler in the device. However, the purification area has a large gas pressure and a high temperature, and there is continuous filler falling and impact, so the working environment is harsh, which makes the feeding monitoring material level meter detection unstable and has a short service life. Therefore, the applicant creatively improves the material level monitoring device, and a detection bin connected with the purification area is arranged below the shell at the front end of the feeding platform, so that when the purification area is filled, the filler will overflow and fall into the detection bin, and then the feeding monitoring material level meter arranged in the detection bin can determine whether the filler in the purification area is filled, and then feedback to the control center to adjust and control the feeding rate of the feeding device or directly alarm. In this way, because the pressure and temperature in the detection bin are much lower than those in the purification area, and the filler does not need to be subjected to long-term falling impact, the stability and reliability of the material level detection can be better ensured, and the service life of the feeding monitoring material level meter is prolonged.

[0067] The shell 1 is outwardly protruded at a position opposite to the front end of the feeding platform to form a protruding portion 19, the front end of the feeding platform and the annular chains on both sides thereof are extended and installed in the protruding portion 19, and a funnel is arranged below the protruding portion 19 and in communication with the upper end of the detection bin 17.

[0068] In this way, when the communication space between the upper end of the detection bin and the upper end of the purification area is blocked, the filler in the purification area rises and accumulates to the position of the feeding platform, and at this time, the filler on the feeding platform cannot fall to both sides and is directly driven by the scraper to the front end and falls into the detection bin, and the feeding monitoring material level meter detects and feeds back the control signal. Therefore, the reliability of the material level monitoring can be better ensured.

[0069] The lower end of the detection bin 17 is provided with a detection bin outlet, and a detection bin outlet valve 20 is installed at the detection bin outlet.

[0070] In this way, the filler in the detection bin can be conveniently discharged.

[0071] The side surface of the detection bin 17 is provided with a mounting port, a detection flange is butt-jointed at the mounting port, and the feeding monitoring material level meter 18 is transversely installed on the detection flange.

[0072] In this way, the feeding monitoring material level meter can be more conveniently mounted and dismounted.

[0073] At least two feeding monitoring material level meters are installed in the detection bin 17 along the height direction.

[0074] In this way, the feedback signal of the lower feed monitoring level gauge can be used to control the feed device to reduce the feed rate, and the feedback signal of the upper feed monitoring level gauge can be used to stop the feed device from feeding, thereby better improving the control effect and ensuring system stability.

[0075] The upper end of the detection bin 17 is further provided with a maintenance aperture 21, and a cover is fixedly installed at the maintenance aperture 21 to realize sealing. In this way, maintenance is facilitated.

[0076] The discharge device comprises a discharge butterfly valve installed at the lower end outlet of the purification area, and further comprises a horizontal conveying device 23 horizontally arranged below the lower end outlet of the purification area. A discharge hopper is connected below the front end of the horizontal conveying device 23, and a discharge bin 24 is connected below the discharge hopper. A discharge valve 25 is installed at the lower end outlet of the discharge bin 24.

[0077] In this way, after the filler loses activity after reacting in the purification area, the discharge butterfly valve is controlled to be opened, the inactivated filler falls from the lower end outlet of the purification area to the horizontal conveying device below, and then is conveyed by the horizontal conveying device to the discharge hopper in front, and then further falls into the discharge bin. When the discharge bin is full, the discharge valve can be opened to discharge the filler. In this way, the inactivated filler is smoothly discharged, and the existence of the discharge bin enables the filler in the purification area to be processed in batch or continuously, thereby greatly improving the flexibility of operation.

[0078] The horizontal conveying device 23 is a chain plate conveyor. In this way, the structure is simple and reliable. Of course, other horizontal conveying devices such as a belt conveyor can also be used in implementation.

[0079] The discharge butterfly valve comprises a discharge shaft 26 horizontally arranged at the middle position of the outlet along the length direction of the lower end outlet of the purification area. One end of the discharge shaft 26 is connected with a discharge motor 28 through the outer shell, and discharge rafters 27 are further installed on both sides of the discharge shaft along the axial direction. When the discharge rafters 27 rotate in the horizontal direction, the discharge rafters 27 can be attached to the inner wall at the lower end outlet of the purification area.

[0080] In this way, the discharge shaft is only required to be controlled to rotate by the discharge motor, and then the gap between the discharge rafters and the inner wall at the lower end outlet of the purification area is adjusted, thereby realizing the control of the discharge rate and the closing.

[0081] A partition valve 29 is further installed at the lower end of the discharge hopper.

[0082] In this way, when the discharge bin is discharged, the partition valve can be closed first, and the inactivated filler is temporarily stored in the discharge hopper. After the discharge bin is discharged and the discharge valve is closed, the partition valve is opened. In this way, the discharge bin can be prevented from being discharged, and the safety is better improved.

[0083] In the upper end position of the discharge bin 24, a discharge level meter 30 is also installed. In this way, the discharge can be reminded in time after the deactivated filler is filled in the discharge bin.
