Background
The honeycomb SCR denitration catalyst is a catalyst applied to a denitration system, and can lose effectiveness after being used for a certain time, and needs to be regenerated. In the regeneration treatment process, the honeycomb type SCR denitration catalyst is generally cleaned first, and then the cleaned honeycomb type SCR denitration catalyst is dried.
For example, chinese patent publication No. CN205825641U discloses a drying device for regenerating honeycomb SCR denitration catalyst, which comprises a drying bin and a circulating air pipe; a horizontally arranged rotary table is arranged in the drying bin, and a fixing frame for placing a honeycomb SCR denitration catalyst is arranged on the top surface of the rotary table; the circulating air pipe is sequentially provided with: dust collector, circulating fan and heating jacket. A drying device of the honeycomb SCR denitration catalyst disclosed in Chinese patent publication No. CN205825615U comprises a drying bin and a circulating air pipe; a vertical rotating shaft is arranged at the top of the drying bin; a hoisting device is fixed at the bottom end of the rotating shaft; the side wall of the drying bin is fixedly provided with a plurality of horizontally arranged annular infrared heating pipes, each annular infrared heating pipe is vertically and uniformly distributed along the side wall of the drying bin, and a single annular infrared heating pipe is circumferentially arranged along the side wall of the drying bin; the circulating air pipe is provided with a dust removing device and a circulating fan.
In the prior art including the device, the catalyst is basically transversely arranged in the drying bin, then hot air is sent into the honeycomb channel in the catalyst through the circulating fan, and the hot air takes away moisture on the inner wall of the honeycomb channel in the horizontal flow process in the channel, however, the drying mode has the following problems in actual operation: on the one hand, because the inside of the catalyst is not a compact structure similar to metal, but a plurality of mutually communicated fine pores exist, water slowly infiltrates through the mutually communicated fine pores under the action of self gravity in the drying process, so that the water in the catalyst is much less; because the temperature and the flow rate of the hot air entering each channel of the catalyst are not different, the drying time required by the catalyst from top to bottom is gradually increased, and the drying time can only be prolonged in order to ensure the whole drying effect of the catalyst in industry, so that the dried part of the upper part of the catalyst has to be contacted with the hot air for a period of time in a drying state, the energy is consumed, and the deformation and cracking of the upper part of the catalyst caused by excessive drying can be caused; on the other hand, the honeycomb channels in the catalyst have a certain length, and the hot air temperature in the channels is different because the hot air always exchanges heat with the catalyst when passing through the channels, and in particular, the lower the hot air temperature is, the worse the drying effect is, the closer the hot air temperature is to the outlet of the channels; the hot air dries the front section of the channel and then contains a part of water, so that the drying effect of the hot air containing water is poorer than that of the hot air, and the drying effect of the hot air containing water in the channel near the outlet is further reduced; similarly, in order to ensure the whole drying effect of the catalyst, the industry can only prolong the drying time, so that the dried part of the catalyst close to the inlet of the channel has to be contacted with hot air for a period of time in a dry state, which consumes energy and can cause deformation and cracking of the end of the catalyst close to the inlet of the channel due to excessive drying.

Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 2, the present embodiment provides a drying mechanism for a honeycomb SCR denitration catalyst 13, including:
a support assembly 1 for supporting the catalyst 13 so that the honeycomb channels are kept vertically clear;
and a heating assembly 2 for conveying dry hot air from bottom to top into the honeycomb channels.
Specifically, the catalyst 13 is kept in a stable state all the time under the supporting action of the supporting component 1 in the drying process, the heating component 2 sends dry hot air into a channel in the catalyst 13, the hot air flows upwards from the bottom of the channel, and the hot air exchanges heat with the inner wall of the channel in the flowing process and takes away moisture on the inner wall of the channel; the hot air entering the channel gradually becomes water vapor with lower temperature from bottom to top; in the vertically placed catalyst 13, moisture gradually infiltrates along the fine pores inside the catalyst 13 by gravity, so that the moisture content of the lower portion of the catalyst 13 is higher than that of the upper portion thereof; when the hot air flowing from bottom to top contacts with the lower part of the internal channel of the catalyst 13, the hot air is in a drying high-temperature state, has strong drying performance, and has good drying effect on the lower part of the catalyst 13 with higher water content; in the process of gradually flowing upwards, the heat of the hot air gradually decreases, and the water content gradually increases, so that the hot air becomes water vapor with relatively low temperature, the drying performance of the hot air in the state is reduced, and the upper part of the catalyst 13 with low water content can be just dried.
In summary, the embodiment realizes the effect of drying the lower part of the catalyst 13 with higher water content by using the hot dry air with higher temperature and drying the upper part of the catalyst 13 with lower water content by using the steam with lower temperature, thereby not only ensuring that the catalyst 13 is effectively dried everywhere, but also avoiding the occurrence of deformation and cracking of the catalyst 13 due to excessive drying.
As shown in fig. 2 and 3, the support assembly 1 comprises a horizontal support plate 101, support legs are fixedly arranged at the bottom of the support plate 101, and a limiting plate 102 matched with the catalyst 13 is vertically and fixedly arranged on the support plate 101; the position of the supporting plate 101 corresponding to each channel is provided with a through hole 103 vertically penetrating through the supporting plate 101; specifically, before drying starts, an operator vertically places a single catalyst 13 on the supporting plate 101 by manual work or controlling the existing discharging equipment, the inner side wall of the supporting plate 101 is attached to the outer side wall of the catalyst 13, and the catalyst 13 is positioned, so that after the catalyst 13 falls onto the upper surface of the supporting plate 101, the position of a channel in the catalyst 13 can exactly correspond to the position of the through hole 103; the hot air supplied from the heating assembly 2 enters the channels in the catalyst 13 from bottom to top through the through holes 103, and dries the catalyst 13.
As shown in fig. 2 and 3, the heating assembly 2 comprises a heating box 201 fixedly installed on the bottom surface of the supporting plate 101, an air outlet hole 202 communicated with the inside of the heating box 201 is formed in the position, corresponding to each through hole 103, of the top surface of the heating box 201, and an air inlet 203 is formed in the heating box 201; specifically, the air inlet 203 is externally connected with an air heater, which is a technology existing in the art and will not be described herein; the hot air blower conveys dry hot air into the heating box 201 through the air inlet 203, and the hot air in the heating box 201 enters the corresponding through holes 103 through the air outlet holes 202 and finally enters the channels in the catalyst 13; it should be noted that, when the power of the air heater is high, the hot air entering the heating box 201 is more, the flow velocity of the hot air before entering the air outlet 202 is faster, and the air velocity in the corresponding catalyst 13 channel is faster; when the power of the hot air blower is small, the hot air entering the heating box 201 is less, the flow rate of the hot air before entering the air outlet hole 202 is slower, and the flow rate of the air in the corresponding catalyst 13 channel is slower.
Example 2
As shown in fig. 4 and 6, on the basis of the above embodiment, in this embodiment, a vertical rotating shaft 3 is rotatably installed at a position corresponding to each channel on the supporting plate 101, the number of through holes 103 corresponding to each channel is multiple and uniformly surrounds the corresponding rotating shaft 3, and a plurality of stirring assemblies 4 located above the supporting plate 101 are installed on the rotating shaft 3; the stirring assemblies 4 are uniformly arranged on the rotating shaft 3 from top to bottom, the stirring assemblies 4 comprise a first clamping piece 401 and a second clamping piece 402 which are arranged on the outer wall of the rotating shaft 3 and correspond to each other up and down, and sheet-shaped gauze 403 or other flexible water-absorbable material sheets are fixedly connected between the first clamping piece 401 and the second clamping piece 402; the bottom surface of first clamping piece 401 and the top surface of second clamping piece 402 have all seted up the crack, and the topside and the base of gauze 403 centre gripping respectively are fixed on the bottom surface of first clamping piece 401 and the top surface of second clamping piece 402, and the pivot 3 can drive first clamping piece 401, second clamping piece 402 and gauze 403 synchronous rotation when rotating.
Specifically, in the drying process, the rotating shaft 3 continuously rotates in a directional manner under the action of external force, so that the stirring assemblies 4 are driven to synchronously rotate in the catalyst 13 channel; the first clamping piece 401, the second clamping piece 402 and the gauze 403 are contacted with the hot air rising in the catalyst 13 channel during the rotation process; on the one hand, because the hot air contacted with the inner wall of the catalyst 13 channel contains a certain amount of moisture, namely, the hot air is converted into steam, the gauze 403 with good water absorption absorbs the moisture in the contact process of the rising steam, so that the moisture content of the steam is reduced, and even the steam returns to the state of dry hot air again; the drying performance of the hot air is improved once, so that the hot air is guaranteed to have the drying performance all the time, the situation that the hot air does not have the drying capability when the hot air flows to the upper part of the catalyst 13 due to excessive water content is avoided, and the upper part of the catalyst 13 is guaranteed to be dried; on the other hand, the gauze 403 applies a horizontal force to the rising hot air in the rotation process, so that the hot air in the catalyst 13 channel flows to the inner wall of the catalyst 13 channel, the friction between the hot air and the inner wall of the catalyst 13 channel is increased, the hot air is facilitated to take away the moisture on the inner wall surface of the catalyst 13 channel, and the drying effect of the hot air is improved.
It should be noted that, in the present embodiment, the number of through holes 103 corresponding to each channel is plural and uniformly surrounds the corresponding rotating shaft 3, so that the amount of the hot air entering the channels of the catalyst 13 is larger near the inner walls of the channels of the catalyst 13, and the amount of the hot air near the center of the channels of the catalyst 13 is smaller; and because of the horizontal force exerted by gauze 403 on the hot air, the hot air near the center of the channels of catalyst 13 is pushed to the inner walls of the channels of catalyst 13 again; therefore, most of hot air can be contacted with the inner wall of the catalyst 13 channel, the condition that a large amount of hot air overflows from the top of the catalyst 13 channel under the condition that the hot air is not contacted with the inner wall of the catalyst 13 channel is avoided, and the energy consumption is saved.
As shown in fig. 5, 8 and 9, in this embodiment, the rotating shaft 3 is a hollow shaft, and a water inlet groove 301 located between the first clamping piece 401 and the second clamping piece 402 is formed on the outer wall of the rotating shaft 3 at a position corresponding to each stirring assembly 4, where the water inlet groove 301 is inclined and one end close to the axis of the rotating shaft 3 is lower; it should be noted that, the edge of the water inlet 301 may be tangent to the upper surface of the second clamping piece 402, and the edge of the water inlet 301 may also be a certain distance from the upper surface of the second clamping piece 402, so long as the water on the second clamping piece 402 can flow into the rotating shaft 3 through the water inlet 301, the water on the gauze 403 can enter the rotating shaft 3; the upper surface of the second clamping piece 402 is slightly inclined, and one end close to the water inlet groove 301 is lower, so that water on the second clamping piece 402 can flow into the water inlet groove 301; in this embodiment, the edge of the water inlet tank 301 is tangent to the upper surface of the second clamping piece 402, the second clamping piece 402 is in an arc shape with the middle recessed downwards, the end of the second clamping piece 402 far away from the rotating shaft 3 is sealed, and the connection part of the gauze 403 and the second clamping piece 402 is positioned in the middle of the upper surface of the second clamping piece 402; the bottom of the heating box 201 is fixedly provided with a water storage tank 5, the bottom end of the rotating shaft 3 extends into the water storage tank 5, and the outer wall of the rotating shaft 3 is provided with a water outlet tank 302 positioned in the water storage tank 5; the water in the rotating shaft 3 drops to the bottom end in the rotating shaft 3 from top to bottom and flows out from the water outlet groove 302 to the water storage tank 5; the water storage tank 5 is a water storage tank commonly known in the prior art, and water in the water storage tank can be discharged.
Specifically, the rotating shaft 3 is driven by external force to rotate directionally in the drying process, the gauze 403 rotates along with the rotating shaft 3 and gradually absorbs moisture in hot air, and the moisture in the gauze 403 is gradually increased; when the moisture content of the gauze 403 tends to saturate, the water within the gauze 403 pools down and onto the second clip 402; because the second clamping piece 402 is in an arc shape with the middle being recessed downwards, the end part of the second clamping piece 402 far away from the rotating shaft 3 is sealed, and the joint of the gauze 403 and the second clamping piece 402 is positioned in the middle of the upper surface of the second clamping piece 402, water flowing onto the second clamping piece 402 cannot flow out from the two sides of the second clamping piece 402 and the end part of the second clamping piece 402 far away from the rotating shaft 3, but flows into the rotating shaft 3 from the water inlet groove 301.
As shown in fig. 7, in this embodiment, the outer wall of the rotating shaft 3 protrudes outwards to form an annular boss, a rolling ball 12 is rotatably mounted on the bottom surface of the annular boss, and the rolling ball 12 is in rolling fit with the upper surface of the supporting plate 101, so as to reduce the friction force between the rotating shaft 3 and the supporting plate 101 in the rotating process, and thus, only a small external force is needed to be provided to drive the rotating shaft 3 to rotate; a plurality of blades 6 are fixedly arranged on the outer wall of the rotating shaft 3; the hot air contacts the blades 6 in the process of entering the catalyst 13 channel from the heating box 201 through the air outlet holes 202 and the through holes 103, and drives the rotating shaft 3 to rotate through the blades 6; in embodiment 1, it has been explained that the power of the external air heater can be controlled, when the power of the air heater is high, more hot air enters the heating box 201, the flow rate of the hot air is high, and the speed of the blades 6 driving the rotating shaft 3 to rotate is high; when the power of the air heater is low, less hot air enters the heating box 201, the flow speed of the hot air is low, and the speed of the blades 6 driving the rotating shaft 3 to rotate is low; the rotational speeds of the blades 6, the shaft 3 and the agitation assembly 4 can be controlled by controlling the power of the air heater only.
Example 3
The purpose of this embodiment is to promote water on the gauze 403 to enter the rotating shaft 3 through the water inlet groove 301, so that the gauze 403 absorbing more water can recover the water absorbing capacity; the difference between this embodiment and the previous embodiment is that the edge of the water inlet channel 301 in this embodiment is at a distance from the upper surface of the second clip 402; specifically, as shown in fig. 10, in this embodiment, a first clamping piece 401 is fixedly connected to the outer wall of the rotating shaft 3, a second clamping piece 402 is vertically slidably matched with the outer wall of the rotating shaft 3, when the second clamping piece 402 is at the vertex of the sliding stroke, a cavity corresponding to the position of the water inlet channel 301 is formed between the upper surface of the second clamping piece 402 and the lower surface of the first clamping piece 401, and one end of the cavity far away from the rotating shaft 3 is closed; the top surface of the first clamping piece 401 is a horizontal plane and is provided with a ball 404 capable of rolling along the radial direction of the rotating shaft 3, the ball 404 has a certain weight, and when the rotating shaft 3 drives the stirring assembly 4 to rotate, the ball 404 rolls to one end of the travel away from the rotating shaft 3 due to the centrifugal force; the ball 404 is wound with a pull rope 405 penetrating through the first clamping piece 401 and fixedly connected with the upper surface of the second clamping piece 402, the pull rope 405 is sleeved on the ball 404, and the pull rope 405 is driven to synchronously move in the rolling process of the ball 404, but the pull rope 405 is not further wound on the ball 404; in this embodiment, when the second clip 402 moves to the highest point of the sliding travel, the upper surface of the second clip is tangent to the edge of the water inlet 301.
In an initial state, that is, in a state that the rotating shaft 3 and the stirring assembly 4 are not rotated at rest, the second clamping piece 402 is positioned at the bottommost end of the sliding stroke due to the gravity of the second clamping piece, the ball 404 is positioned at one end of the rolling stroke close to the rotating shaft 3, and the pull rope 405 is in a tensioning state; during the rotation of the rotating shaft 3 and the stirring assembly 4, the balls 404 roll towards one end far away from the rotating shaft 3 under the action of centrifugal force, and pull the second clamping piece 402 to rise through the pull rope 405; since the first clamping piece 401 is fixedly connected to the rotating shaft 3, the distance between the first clamping piece 401 and the second clamping piece 402 is gradually shortened, the gauze 403 between the first clamping piece 401 and the second clamping piece 402 is gradually folded and crimped, and when the second clamping piece 402 slides to the top dead center of the stroke of the second clamping piece 402, the first clamping piece 401 and the second clamping piece 402 have an extrusion effect on the gauze 403, and moisture in the gauze 403 is extruded and flows into the rotating shaft 3 through the water inlet groove 301.
In this embodiment, when the second clip 402 slides to the top dead center of the stroke, a certain gap exists between the upper surface of the second clip 402 and the lower surface of the first clip 401, and the gauze 403 is positioned in the gap when being pressed; the water squeezed out after the gauze 403 is squeezed does not overflow from both sides of the second clamping piece 402 and the end of the second clamping piece 402 away from the rotating shaft 3; in addition, in the actual working of the embodiment, the power of the external air heater is in a periodically changed state, that is, the power of the external air heater regularly becomes larger and smaller, which is the prior art, and is not described herein too; under the condition that the power of the external air heater is changed regularly, the rotation speeds of the blades 6, the rotating shaft 3 and the stirring assembly 4 are also changed regularly; when the speed of the rotating shaft 3 and the stirring assembly 4 is high, the balls 404 are subjected to high centrifugal force, the balls 404 can roll from the initial position to one end far away from the rotating shaft 3, and the corresponding first clamping piece 401 and the second clamping piece 402 squeeze water from the gauze 403; when the speed of the rotating shaft 3 and the stirring assembly 4 is reduced, the balls 404 are subjected to smaller centrifugal force, the balls 404 are insufficient to pull the second clamping piece 402 to rise through the pull rope 405, and the second clamping piece 402 slides downwards to return to the bottom end of the sliding stroke under the action of gravity; the second clip 402 is reset by pulling the ball 404 by the pull cord 405 during the sliding down, and the gauze 403 is also folded back from the folded back to the flat state, thereby having the functions of absorbing water and applying horizontal force to the hot air again.
In summary, in this embodiment, only the power of the external air heater is set to be in a periodically changed state, so that water on the gauze 403 can be promoted to enter the rotating shaft 3 through the water inlet groove 301, and the water absorbing capacity of the gauze 403 absorbing more water can be recovered.
Example 4
On the basis of the above embodiment, the purpose of this embodiment is to collect hot air overflowing from the top of the channel, send this part of uncooled dry hot air back to the inlet of the hot air blower, recycle the heat, avoid the waste of energy consumption.
Specifically, as shown in fig. 11, the drying mechanism of the honeycomb SCR denitration catalyst 13 in this embodiment further includes a cover plate 7, where the cover plate 7 is of a detachable and combined upper and lower split structure, and a cavity is formed inside the cover plate 7; the edge of the cover plate 7 is vertically and fixedly provided with a locating plate 8 matched with the limiting plate 102; the bottom surface of the cover plate 7 is provided with an air inlet pipe 9 which is communicated with the cavity inside the cover plate 7 at the position corresponding to each channel, and the inner diameter of the air inlet pipe 9 is consistent with the inner diameter of the channel; the positioning sheet 8 is matched with the limiting plate 102 to position the cover plate 7, so that the positions of the air inlet pipe 9 and the catalyst 13 are in one-to-one correspondence; the side wall of the cover plate 7 is fixedly provided with a gas pipe 10 communicated with the cavity inside the cover plate, and the gas pipe 10 is communicated with the inlet of the air heater through a hose connected with the outside.
Since the agitation assembly 4 in the present embodiment absorbs moisture in the hot air while horizontally agitating the hot air in the channels of the catalyst 13 so that the hot air is restored to a dry state, the hot air flowing out from the top of the channels of the catalyst 13 is dry hot air; the part of dry hot air enters the cover plate 7 through the air inlet pipe 9 and flows from the air delivery pipe 10 and the hose to the inlet of the external hot air blower; in this way, the hot air flowing out from the top of the catalyst 13 channel can be reused, and the heat energy contained in the catalyst is not wasted; in summary, this embodiment automatically realizes the separation of the hot air and the moisture in the drying process of the catalyst 13, and can collect the separated moisture, and reutilize the separated hot air, thereby avoiding the waste of energy consumption.
