Description

Technical Field

[0001] The invention relates to the technical field of pollution treatment and sludge drying, and in particular to a novel steam generating device for sludge drying. Background Art

[0002] Steam drying sludge is an efficient sludge treatment method that mainly uses the thermal energy of steam to evaporate the water in the sludge, thereby achieving sludge drying and reduction; steam directly contacts the sludge, and through heat transfer, the water in the sludge evaporates rapidly, thereby achieving rapid drying. This contact method improves the drying efficiency and effectively reduces the volume of the sludge.

[0003] When the sludge is in a piled state, the outer layer is more likely to come into contact with the space, allowing the moisture to be carried away by the air and easier to dry, while the internal sludge is difficult to come into contact with the air. At the same time, due to the interaction between the internal sludge isolation spaces and the binding force between the particles, it is difficult for the moisture to evaporate from the particles. At present, steam is used to dry the sludge, and the drying speed of more sludge is slower. At the same time, when steam is used to dry the sludge, the sludge located on the outside is easier to dry. The drying of the external sludge will still absorb a certain amount of heat, affecting the drying effect of the internal sludge. At the same time, when steam is used to dry the sludge, if there is contact, the moisture contained in the steam and the condensed water will have a certain negative impact on the drying of the sludge.

[0004] For example, the existing patent (Announcement No.: CN113480135B) and a sludge double drying device and method, in which superheated steam and high thermal radiation contact the sludge to form a drying effect. The sludge that first contacts the superheated steam and high thermal radiation will have a better drying effect than other parts. If not handled in time, this will lead to different degrees of drying of the shallow and deep layers of the sludge. The deep sludge drying requires a longer time period, affecting the sludge drying efficiency.

A connector matching the sliding nested nested pipe is provided on the top of the delivery pipe, and a water discharge hole is provided at the bottom of the delivery pipe.

[0010] Both sides of the outer wall of each sludge box are provided with a dumping assembly, and the dumping assembly includes a hydraulic push rod, and the hydraulic push rod has a built-in stroke sensor;

[0011] Each of the humidity detection modules corresponds to the segmented stroke signal of the stroke sensor, and the drying signal of any humidity detection module activates the hydraulic push rod to move it to the segmented stroke signal of the stroke sensor corresponding thereto.

[0012] Preferably, the sludge box is divided into three parts according to the depth, namely, a front layer, a middle layer and a deep layer, and the sludge box is respectively provided with three humidity detection modules corresponding to the three parts.

[0013] Preferably, four groups of the steam tubular components are arranged inside the sludge box, and four groups of the guide pipes are correspondingly arranged for the four groups of the steam tubular components.

[0014] Preferably, one side opening of the bent conduit is bent upward, and a filter element is installed at the bent upward portion of the bent conduit, and the other side opening of the bent conduit is located on the outer wall of the delivery pipe.

[0015] Preferably, a movable sleeve is slidably mounted on the outer wall of the tube seat of the nested tube, and a return spring for elastic nesting is arranged between the movable sleeve and the tube seat.

[0016] Preferably, the connector is in the shape of a triangular plate extending along a circular mouth, so that when the sludge tank is dumped, the connector of the delivery pipe pushes the movable sleeve to move, and the movable sleeve contracts through a reset spring so that the delivery pipe passes through the connector and detaches from the movable sleeve.

[0017] Preferably, the connector is in the shape of a triangular plate extending along a circular mouth, so that when the sludge tank is reset after being dumped, the connector of the delivery pipe pushes the movable sleeve to move, and the movable sleeve contracts through a reset spring so that the delivery pipe passes through the connector and enters the movable sleeve.

[0018] Preferably, an air booster pump is installed on the top of the steam tank of the steam generating component, and the air inlet and the air outlet of the air booster pump are both connected to the exhaust pipe.

[0019] Preferably, the end of the movable rod of the hydraulic push rod is connected to the outer shaft of the corresponding rotating shaft through a movable joint, and the inner shaft of the rotating shaft is fixed to the outer wall of the sludge box.

[0022] Compared with the related art, the steam generating device for novel sludge drying provided by the present invention has the following beneficial effects:

[0023] 1. The present invention disperses and dries the accumulated sludge through the sludge box, and detects the sludge at different depths in the sludge box through the humidity detection module. Since shallow sludge is easier to dry, when the shallow humidity detection module detects that the humidity reaches a threshold value, the dumping component is started, and the electric push rod drives the movable rod to push the rotating shaft through the movable joint so that the sludge box is dumped with the central axis as the circle point, and the stroke of the movable rod is detected by the stroke sensor. When the movable rod moves to the stroke corresponding to the shallow humidity detection module, it stops, that is, the sludge box reaches the angle corresponding to the shallow sludge drying and dumping, and the shallow sludge is dumped out. Similarly, the dumping methods of the middle and deep layers of sludge are the same, which is conducive to the dispersed batch drying of a large amount of sludge, and is conducive to dumping the sludge in sections according to the actual drying time, which is conducive to greatly improving the drying speed of the sludge.

[0024] 2. The present invention arranges the nested sleeve and the steam tubular component, so that when the sludge tank is dumped, the connector of the delivery pipe pushes the movable sleeve to move, and the movable sleeve contracts through the reset spring so that the delivery pipe passes through the connector and separates from the movable sleeve. When the sludge tank is reset after being dumped, the connector of the delivery pipe pushes the movable sleeve to move, and the movable sleeve contracts through the reset spring so that the delivery pipe passes through the connector and enters the movable sleeve, which is beneficial to complete the separation of the guide pipe and the delivery pipe when the sludge tank is dumped, and is beneficial to complete the nested connection of the guide pipe and the delivery pipe when the sludge tank is dumped and reset.

[0025] 3. The four groups of steam tubular components of the present invention are arranged, steam is sent into the conveying pipe through the guide pipe, and then the steam is discharged from the bent conduit to contact the sludge in the sludge box. The sludge cannot enter the conveying pipe through the bending structure and the filter element structure. The steam is sent into the sludge box by a plurality of bent conduits. The flow of steam can destroy the binding force between the sludge particles, making it easier for the moisture to evaporate. The four groups of conveying pipes can make the heat of the steam contact the sludge in the sludge box more uniformly. At the same time, the moisture carried by the steam and the condensed water generated by the steam are discharged from the water outlet, which is beneficial to make the sludge in the sludge box contact the heat more uniformly and to reduce the influence of the moisture generated by the steam on the dried sludge.

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] A novel steam generating device for sludge drying comprises a shell 1, a sludge pipe 2 is arranged above the shell 1, and a feeding pipe is arranged equidistantly on the sludge pipe 2 corresponding to a sludge box 3, and external sludge is connected to the feeding pipe via a sludge pump and is fed into the sludge box 3 via the feeding pipe through the sludge pump, and one feeding pipe corresponds to one sludge box 3, and one electric control valve can be installed on a single feeding pipe to control the opening time, and stop opening when the sludge box 3 is full;

[0038] The housing 1 has equidistantly arranged segmented dumping sludge boxes 3 built in, a base 4 is installed at the bottom of the sludge box 3, a central axis 41 for dumping the sludge box 3 is installed on one side of the base 4, the front side of the bottom of the sludge box 3 is placed on the base 4, the sludge box 3 rotates through the central axis 41 in the middle of its bottom surface, and the side wall of the sludge box 3 is equidistantly arranged according to the depth. The humidity detection module 32 is a humidity sensor. The humidity sensor utilizes the hygroscopic properties of the material, such as humidity-sensitive resistors and humidity-sensitive capacitors. When water molecules come into contact with the humidity-sensitive material, its conductivity or dielectric constant will change;

[0039] A steam generating component 6 is installed on the left side of the shell 1. The steam generating component 6 is mainly composed of three parts: a combustion system, a furnace body and a condenser. The combustion system is responsible for providing heat energy, and the condenser is mainly used to preheat the incoming water and release waste heat and latent heat, and further reduce the exhaust gas temperature, so that the heat generated by the combustion of the gas can be fully utilized;

[0040] The steam tank 62 is composed of a boiler drum, a header, a fire tube, a furnace, etc. The feed water is heated to a certain temperature in the heater, enters the economizer through the feed water pipe, and is further heated before being sent to the boiler drum. After mixing with the boiler water, it flows down the downcomer to the water-cooled wall inlet header. The water absorbs the furnace radiation heat in the water-cooled wall tube to form a steam-water mixture, which reaches the boiler drum through the riser. The steam-water separation device separates the water and steam. The separated saturated steam flows from the upper part of the boiler drum to the superheater, continues to absorb heat to become 450°C superheated steam, and is then sent to the steam turbine to send out the steam.

[0041] The exhaust pipe 63 of the steam generating component 6 is respectively provided with a guide pipe 64 corresponding to the sludge box 3, and the steam is guided by the guide pipe 64. The end of the guide pipe 64 is connected to the corresponding delivery pipe 312 through a nested pipe 65;

[0042] A movable sleeve 653 is slidably mounted on the outer wall of the tube seat 651 of the nested tube 65, and a return spring 652 for elastic nesting is arranged between the movable sleeve 653 and the tube seat 651;

[0043] The movable sleeve 653 is movably nested in the outer wall of the tube seat 651, and the return spring 652 is stretched to make the movable sleeve 653 always in the expanded state.

[0044] Steam tubular components 31 are evenly arranged inside the sludge box 3, and bent conduits 314 are evenly arranged inside the delivery pipe 312 of the steam tubular component 31. The steam generated by the steam generating component 6 is sequentially delivered into the sludge box 3 through the exhaust pipe 63, the guide pipe 64, the nested pipe 65, the delivery pipe 312 and the bent conduit 314. A connector 311 matching the sliding nested nested pipe 65 is arranged on the top of the delivery pipe 312, and a water hole 315 is opened at the bottom of the delivery pipe 312. The moisture carried by the steam and the condensed water generated by the steam are discharged through the water hole 315.

[0045] The connector 311 is in the shape of a triangular plate extending along the circular mouth. When the sludge box 3 is tilted, the connector 311 of the conveying pipe 312 pushes the movable sleeve 653 to move, and the movable sleeve 653 is contracted by the return spring 652 so that the conveying pipe 312 passes through the connector 311 and separates from the movable sleeve 653; when the sludge box 3 starts to tilt, the conveying pipe 312 is tilted along with the sludge box 3, so that the movable sleeve 653 rises from the inside along the inclined edge of the connector 311 to the highest point, and the rise of the movable sleeve 653 pushes the return spring 652 to contract. When the return spring 652 contracts, the movable sleeve 653 rises along the pipe seat 651, and after the movable sleeve 653 reaches the highest point of the connector 311, the movable sleeve 653 separates from the range of the conveying pipe 312.

[0046] When the sludge tank 3 is reset after being dumped, the connector 311 of the delivery pipe 312 pushes the movable sleeve 653 to move, and the movable sleeve 653 is contracted by the reset spring 652 so that the delivery pipe 312 passes through the connector 311 and enters the movable sleeve 653;

[0047] When the sludge box 3 is dumped and begins to reset, the delivery pipe 312 is reset along with the sludge box 3, so that the movable sleeve 653 rises from the outside along the inclined edge of the connector 311 to the highest point. The rise of the movable sleeve 653 pushes the return spring 652 to contract. The movable sleeve 653 rises along the pipe seat 651 when the return spring 652 contracts. After the movable sleeve 653 reaches the highest point of the connector 311, the movable sleeve 653 enters the range of the delivery pipe 312.

[0048] A dumping assembly 5 is provided on both sides of the outer wall of each sludge box 3, and the dumping assembly 5 includes a hydraulic push rod 51. The end of the movable rod 53 of the hydraulic push rod 51 is connected to the outer axis of the corresponding rotating shaft 54 ​​through a movable joint 55, and the inner axis of the rotating shaft 54 ​​is fixed to the outer wall of the sludge box 3. The movable rod 53 is unfolded by starting the hydraulic push rod 51, and the end of the movable rod 53 is connected to the outer axis of the rotating shaft 54 ​​through a movable joint 55. The movable joint 55 is specifically a single plate provided at the end of the movable rod 53, and a double plate is provided on the outer wall of the outer axis of the rotating shaft 54. The single plate is inserted between the corresponding double plates and penetrated by bolts. The inner axis of the rotating shaft 54 ​​is fixed to the center position of the outer wall of the sludge box 3, and the outer axis of the rotating shaft 54 ​​rotates around the inner axis.

[0049] The hydraulic push rod 51 is built with a stroke sensor 52, which detects the stroke value of the movable rod 53 inside the hydraulic push rod 51. A capacitive stroke sensor 52 can be used, which uses the electric field formed between two metal plates parallel to each other and at a certain distance to measure the displacement of an object or equipment;

[0050] Each of the humidity detection modules 32 corresponds to the segmented stroke signal of the stroke sensor 52. The drying signal of any humidity detection module 32 activates the hydraulic push rod 51 to move it to the segmented stroke signal of the stroke sensor 52 corresponding thereto.

[0051] The sludge box 3 is divided into three parts according to the depth, namely, the front layer, the middle layer and the deep layer. The sludge box 3 is respectively provided with three humidity detection modules 32 corresponding to the three parts.

[0052] The accumulated sludge is dispersed and dried through the sludge box 3, and the sludge at different depths in the sludge box 3 is detected through the humidity detection module 32. The shallow sludge is easier to dry because the shallow sludge is more likely to be exposed to the external flowing air. At the same time, the steam is sent into the conveying pipe 312 from top to bottom. The shallow sludge is the first part to be exposed to the heat of the steam. The steam conveyed to the deep sludge must pass through the shallow sludge before passing through the deep sludge and then evaporate into the air. This also means that the amount of steam gas passed by the shallow sludge is the largest, so the shallow sludge is often easier to dry than the middle and deep sludge.

[0053] When the shallow humidity detection module 32 detects that the humidity reaches the threshold value, the dumping assembly 5 is started, and the electric push rod drives the movable rod 53 to push the rotating shaft 54 ​​through the movable joint 55 so that the sludge box 3 is dumped with the central axis 41 as the center point, and the stroke sensor 52 detects the stroke of the movable rod 53. When the movable rod 53 moves to the stroke corresponding to the shallow humidity detection module 32, it stops, that is, the sludge box 3 reaches the angle corresponding to the shallow sludge drying and dumping, and the shallow sludge is dumped out. Similarly, the dumping methods of the middle and deep sludge are the same;

[0054] It should be noted that after the shallow sludge is dumped, the bent conduit 314 originally in the shallow layer still discharges steam, and the heat of the steam can increase the temperature of the air above the exposed middle layer sludge, thereby increasing the drying speed of the middle layer sludge.

[0055] When the dumping assembly 5 is started, that is, the stroke value of the stroke sensor 52 of the hydraulic push rod 51 is greater than 0, the air booster pump 61 of the steam generating component 6 is paused; when the dumping assembly 5 is reset, that is, the stroke value of the stroke sensor 52 of the hydraulic push rod 51 is equal to 0, the air booster pump 61 of the steam generating component 6 is started.

[0056] Preferably, four groups of the steam tubular components 31 are arranged inside the sludge box 3, and four groups of the guide pipes 64 are correspondingly arranged for the four groups of the steam tubular components 31. The steam enters the steam tubular components 31 through the guide pipes 64, and the temperature of the steam is absorbed by the steam tubular components 31, and then the heat is transferred to the sludge. The heat of the steam tubular components 31 can dry the sludge.

[0057] Preferably, one side opening of the bent conduit 314 is bent upward, and a filter element 313 is installed at the bent upward portion of the bent conduit 314, and the other side opening of the bent conduit 314 is located at the outer wall of the delivery pipe 312;

[0058] The upwardly bent conduit 314 can prevent the sludge from flowing back into the delivery pipe 312 , and further block the microorganisms and organic matter in the sludge from entering the delivery pipe 312 through the filter element 313 , thereby preventing the microorganisms and organic matter in the sludge from flowing back into the delivery pipe 312 .

[0059] Preferably, an air booster pump 61 is installed on the top of the steam tank 62 of the steam generating component 6, and the air inlet and outlet of the air booster pump 61 are connected to the exhaust pipe 63. The air booster pump 61 increases the flow rate and air pressure of the steam, so that the steam is quickly discharged from the bent conduit 314, and the steam is sent into the sludge box 3 by several bent conduits 314. The flow of steam can destroy the binding force between the sludge particles, making it easier for moisture to evaporate.

[0060] Preferably, a discharge port 11 is provided on the outer wall of the shell 1 corresponding to the dumping side of the sludge box 3, and the number and position of the discharge port 11 correspond to the number and position of the sludge box 3 one by one. A guide bucket 33 is provided on the dumping side of the sludge box 3. When the sludge box 3 is dumped, the sludge in the sludge box 3 is poured out through the guide bucket 33, and the sludge box 3 extends out of the discharge port 11 to push the sludge out;

[0061] The top wall of the housing 1 is provided with an exhaust fan 7 corresponding to the sludge box 3, and two exhaust fans 7 are provided corresponding to the top of the single sludge box 3.

[0062] The air in the housing 1 is quickly exhausted by the exhaust fan 7, and the air containing moisture is quickly taken away. At the same time, the air flow inside the housing 1 is also accelerated, so that the sludge surface dries more quickly.

[0063] Working principle: External sludge is fed into the corresponding sludge pipe 2 through the sludge pump, and the sludge enters the sludge box 3 through the feeding pipe of the sludge pipe 2;

[0064] By starting the steam generating component 6, the combustion system in the steam tank 62 provides heat, the feed water is heated to a certain temperature in the heater, and the saturated steam flows from the upper part of the steam tank 62 to the heat absorber to become 450°C superheated steam, which is sent to the sludge tank 3 through the exhaust pipe 63, and the flow rate of the steam is increased by the air booster pump 61;

[0065] The steam is sequentially delivered to the sludge tank 3 through the exhaust pipe 63, the guide pipe 64, the nested pipe 65, the delivery pipe 312 and the bent conduit 314. The steam is delivered to the delivery pipe 312 through the guide pipe 64, and then the steam is discharged from the bent bent conduit 314 to contact the sludge in the sludge tank 3. The sludge cannot enter the delivery pipe 312 due to its bent structure and the filter element 313 structure. At the same time, the steam can quickly increase the temperature of the delivery pipe 312, and the temperature of the delivery pipe 312 is transmitted to the sludge in the sludge tank 3, and then the temperature is used to quickly volatilize the moisture of the sludge. The four groups of delivery pipes 312 can make the heat of the steam contact the sludge in the sludge tank 3 more evenly. At the same time, the moisture carried by the steam and the condensed water generated by the steam will appear in the delivery pipe 312 and be discharged from the water outlet 315.

[0066] Steam is sent into the sludge box 3 by a plurality of bent conduits 314. The flow of steam can destroy the binding force between sludge particles, making it easier for water to evaporate.

[0067] The accumulated sludge is dispersed and dried through a plurality of sludge boxes 3, and the sludge at different depths in the sludge box 3 is detected through the humidity detection module 32. Since the shallow sludge is easier to dry, when the shallow humidity detection module 32 detects that the humidity reaches a threshold value, the dumping assembly 5 is started, and the electric push rod drives the movable rod 53 to push the rotating shaft 54 ​​through the movable joint 55 so that the sludge box 3 is dumped with the central axis 41 as the center point. When the sludge box 3 is dumped, the connector 311 of the conveying pipe 312 pushes the movable sleeve 653 to move, and the movable sleeve 653 contracts through the reset spring 652 so that the conveying pipe 312 passes through the connector 311 and is separated from the movable sleeve 653, and the travel sensor 652 is used to transfer the sludge to the movable sleeve 653. The sensor 52 detects the stroke of the movable rod 53 and stops when the movable rod 53 moves to the stroke corresponding to the shallow humidity detection module 32, that is, the sludge box 3 reaches the angle corresponding to the shallow sludge drying and dumping, and the shallow sludge is dumped out. Similarly, the middle and deep sludge are dumped in the same way. When the sludge box 3 is reset after dumping, the connector 311 of the conveying pipe 312 pushes the movable sleeve 653 to move, and the movable sleeve 653 contracts through the reset spring 652 so that the conveying pipe 312 passes through the connector 311 and enters the movable sleeve 653. The steam continues to be delivered into the sludge box 3 through the exhaust pipe 63, the guide pipe 64, the nested pipe 65, the conveying pipe 312 and the bent conduit 314.

[0068] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
