Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment equipment, and more specifically, to a drying module and a drying device. Background Art

[0002] When performing wastewater treatment operations, it is necessary to treat various complex high-salt wastewaters, and the drying bed has a good treatment effect on this.

[0003] The high-salt wastewater and hot air are sent into the drying bed, and the hot air provides the necessary heat source for the drying of the high-salt wastewater. For example, the high-salt wastewater is evenly sprayed on the surface of the inert particles in the drying bed through a nozzle or a liquid distribution pipe, and is fully contacted and dried with the hot air to form a slurry. Then the slurry forms a solid, which is evenly attached to the surface of the inert particles. Then, the particles are blown by the air flow to make the particles grind against each other, and the solid becomes dust and is carried out of the drying bed by the air flow.

[0004] The mutual grinding between the inert particles is likely to cause problems such as particle fouling and air distribution plate blockage after running for a period of time. It is necessary for maintenance personnel to enter the drying bed to clean out hundreds of kilograms of inert particles from the drying bed, and then clean the inert particles and the air distribution plate. There are problems such as long maintenance time, high maintenance frequency, and high labor intensity during daily maintenance.

[0005] Therefore, a drying module and a drying device are needed to solve the above problems. Summary of the Invention

[0029] To make the purpose, technical solution and advantages of the present application clearer and more understandable, the following further details the present application in conjunction with specific embodiments and with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0030] Figure 1 It is a schematic diagram of the drying module adopted in the specific embodiment of the present application. Figure 2 It includes Figure 1 A schematic diagram of a drying device including the drying module shown. As Figures 1 to 2 shown, the drying module includes: a drying bed wall 9, a packing layer, a support mechanism and a driving mechanism.

[0031] A receiving cavity is provided inside the drying bed wall 9; the drying bed wall 9 is usually arranged as a hollow structure or a drawer structure.

[0032] The packing layer is arranged in the receiving cavity; the drying bed wall 9 provides a receiving space for the packing layer, and the wastewater and hot air come into full contact at the packing layer. The packing layer can increase the contact area between gas and liquid and prolong the residence time, which helps to achieve sufficient drying.

[0033] In an embodiment of the present application, the packing layer is filled with inert particles.

[0034] At least one through hole is provided on the support mechanism, and the support mechanism is used to support the drying bed wall 9; the support mechanism is used to support the drying bed wall 9 and the packing layer, and the gas enters the receiving cavity through the through hole, and the purified water flows out through the through hole.

[0035] The driving mechanism is connected to the supporting mechanism and can drive the supporting mechanism to move reciprocally. The driving mechanism can drive the supporting mechanism to carry the drying bed wall 9 and the packing layer to move reciprocally along a preset path.

[0036] In an embodiment of the present application, the driving mechanism includes but is not limited to a hydraulic mechanism 4. The driving end of the hydraulic mechanism can enter the interior of the drying bed to push and pull the drying module in and out of the drying bed.

[0037] The drying bed wall 9 serves as the main body of the drying module and at the same time as a component of the drying device (such as a drying bed), and can move relative to the drying bed. The drying module is installed in the drying bed. When hot air enters the drying bed and passes through the drying module, the inert particles in the packing layer are in a fluidized state. The wastewater is sprayed on the surface of the inert particles and undergoes heat and mass exchange with the hot air. After the dried slurry is ground by the collision of the inert particles, it becomes powdery and falls off from the surface of the inert particles, and then is carried away by the hot air and separated from the drying module. When the drying effect of the drying module significantly decreases, the driving mechanism drives the supporting mechanism to disengage from the working position. After the maintenance personnel process the drying module or replace the new packing layer and the drying bed wall 9, the driving mechanism drives the supporting mechanism to reset to the working position.

[0038] With the above drying module, during the daily maintenance of the drying bed, when problems such as fouling of inert particles and blockage of through holes are encountered, the driving mechanism can be started to move the drying bed wall 9, the packing layer, etc. out of the drying bed, and the spare drying bed wall 9, the packing layer, etc. are pushed into the drying bed to complete the rapid replacement of the main part of the drying module, ensuring the drying effect and the continuity of use of the drying bed. The replaced drying bed wall 9, the packing layer, etc. can be repaired and cleaned for standby for the next maintenance and repair of the drying bed. This not only shortens the maintenance time and the equipment shutdown time, but also improves the maintenance efficiency and reduces the labor intensity.

[0039] In order to achieve uniform air distribution into the packing layer, optionally, the drying module further includes: a air distribution mechanism, the air distribution mechanism is arranged on the supporting mechanism and / or the drying bed wall 9, and the air distribution mechanism is used to make the air flow evenly distributed in the accommodation cavity. The air distribution mechanism can achieve uniform air supply to the packing layer. However, when the air distribution mechanism is blocked due to fouling of inert particles, it should be dealt with in a timely manner. Therefore, by installing the air distribution mechanism on the supporting mechanism or the drying bed wall 9, it can be moved out of the drying bed together with the drying bed wall 9 and the supporting mechanism, and the air distribution effect can be ensured by repairing or replacing the air distribution mechanism.

[0040] In an embodiment of the present application, the air distribution mechanism includes but is not limited to an air distribution plate 5, and a plurality of air distribution holes are evenly distributed on the air distribution plate 5.

[0041] In one embodiment of the present application, the air distribution plate 5 is usually arranged on the support mechanism, and can also be arranged on the drying bed wall 9, such as the middle and lower parts of the drying bed wall 9, etc.; it can also be arranged between the support mechanism and the drying bed wall 9.

[0042] In order to uniformly supply wastewater to the packing layer, optionally, the drying module further includes: a spraying mechanism arranged on the drying bed wall 9, and the spraying mechanism is used to supply liquid to the packing layer. The spraying mechanism can uniformly spray liquids such as wastewater and spraying liquid into the packing layer. The spraying mechanism rarely gets blocked. When disassembling the drying module, the spraying mechanism can be removed from the drying bed wall 9 and retained in the drying bed. Arranging the spraying mechanism on the drying bed wall 9 is to shorten the spraying distance, retain the spraying impact force, and can also wash the packing layer to avoid blockage of the packing layer.

[0043] In one embodiment of the present application, the spraying mechanism includes a plurality of spraying pipes 11, the spraying pipes 11 are communicated with the wastewater source, and the plurality of spraying pipes 11 are uniformly distributed along the drying bed wall 9. The spraying ranges between adjacent spraying pipes 11 may not interfere with each other or slightly overlap, so as to avoid blind areas, so that the overall spraying range of the plurality of spraying pipes 11 can fully cover the packing layer.

[0044] In order to make the water flow and the air flow fully contact, optionally, the air distribution mechanism and the spraying mechanism are respectively arranged at opposite ends of the drying bed wall 9, so that the air flow provided by the air distribution mechanism and the water flow provided by the spraying mechanism can move towards each other.

[0045] In one embodiment of the present application, the spraying mechanism is arranged above the drying bed wall 9 relatively, the water flow moves downward relative to the packing layer, the air distribution mechanism is arranged below the drying bed wall 9 relatively, the air flow moves upward relative to the packing layer, and they fully contact in the packing layer to achieve the drying purpose; the purified water flows downward below the packing layer, and the air flow that has lost heat flows upward above the packing layer.

[0046] Optionally, the support mechanism includes: a pallet 7 and a traveling unit connected to the pallet 7. Through holes are arranged on the pallet 7, and the pallet 7 can support the drying bed wall 9. The pallet 7 provides a supporting effect for the drying bed wall 9 and the packing layer. Through holes are arranged on the pallet 7, and the air distribution mechanism is arranged in the through holes, which can not only achieve uniform air distribution, but also prevent the packing from separating from the packing layer. In order to reduce the moving resistance of the pallet 7 and the driving difficulty of the driving mechanism, a traveling unit is installed on the pallet 7, and the traveling unit enables the pallet 7 to move along a preset path. When the driving mechanism drives the pallet 7 or the traveling unit, the traveling unit drives the pallet 7 and the drying bed wall 9, the packing layer, etc. above it to move synchronously.

[0047] In one embodiment of the present application, the traveling unit includes but is not limited to a wheeled traveling unit, a sliding traveling unit, etc.

[0048] To reduce the assembly difficulty and facilitate driving, optionally, the walking unit includes a slider and a slide rail 8. The slider is connected to the pallet 7, and the slide rail 8 is laid at a preset position. The slider can reciprocate along the slide rail 8. Usually, two groups of slide rails 8 are provided. The two groups of slide rails 8 are located relatively below the pallet 7, arranged opposite to each other and at intervals. The extending direction of the slide rail 8 coincides with the moving direction of the pallet 7. One or more sliders can be provided on the slide rail 8, and the slider can reciprocate along the slide rail 8. Each slider is fixed on the pallet 7. When the driving mechanism pushes and pulls the pallet 7, the slider below the pallet 7 reciprocates along the slide rail 8.

[0049] Optionally, the through hole is a sunken hole, and the air distribution mechanism is arranged in the sunken hole. The air distribution mechanism usually has a moving thickness. By using the sunken hole to install the air distribution mechanism, it can ensure the effective contact between the pallet 7 and the drying bed wall 9 and ensure the sealing performance.

[0050] The following further introduces the usage process of the drying module.

[0051] Install the drying module in the drying bed. The drying bed is in a relatively closed state. Hot air enters the drying bed. After the hot air is distributed by the air distribution mechanism, it passes through the drying module. The hot air makes the inert particles in the packing layer in a fluidized state. The spraying mechanism sprays the wastewater on the surface of the inert particles. The wastewater exchanges heat and mass with the hot air. After the dried slurry is ground by the collision between the inert particles, it becomes powdery and falls off from the surface of the inert particles, and then is carried away by the hot air and exits the drying bed. When the drying effect of the drying module significantly decreases, the driving mechanism drives the supporting mechanism to move, and the walking unit enables the pallet 7 to carry the drying bed wall 9, the packing layer, and the air distribution mechanism to withdraw from the working position, such as exiting the drying bed from the inspection port. After the maintenance personnel process the drying module or replace the new packing layer, air distribution mechanism, and drying bed wall 9, the driving mechanism drives the supporting mechanism to reset to the working position.

[0052] This application also provides a drying device, including: a tower body 3 and the drying module as described above.

[0053] An inlet tower opening 6 and an outlet tower opening 1 are respectively arranged at opposite ends of the tower body 3; an inspection port is arranged on the tower body 3, the inspection port is arranged between the inlet tower opening 6 and the outlet tower opening 1, and a sealing plate 10 with an openable and closable connection is arranged at the inspection port;

[0054] The drying module can at least partially enter and exit the tower body 3 through the inspection port.

[0055] Install the drying module inside the drying bed to make the drying bed in a relatively enclosed state; hot air enters the drying bed from the air inlet 6. After the hot air is distributed by the air distribution mechanism, it passes through the drying module. The hot air makes the inert particles in the packing layer in a fluidized state. The spraying mechanism sprays the wastewater on the surface of the inert particles. The wastewater exchanges heat and mass with the hot air. After the dried slurry is ground by the collision between the inert particles, it becomes powdery and falls off from the surface of the inert particles, and then is carried away by the hot air from the drying module and exits the drying bed from the air outlet 1. When the drying effect of the drying module significantly decreases, the driving mechanism drives the supporting mechanism to move, and the walking unit enables the tray 7 to carry the drying bed wall 9, the packing layer, and the air distribution mechanism out of the working position and exit the drying bed from the maintenance opening. After the maintenance personnel process or replace the new packing layer, air distribution mechanism, and drying bed wall 9 for the drying module, the driving mechanism drives the supporting mechanism to reset to the working position.

[0056] When the above drying module is adopted in the drying device, during the daily maintenance of the drying bed, in case of problems such as fouling of inert particles and blockage of through holes, the driving mechanism can be started to move the drying bed wall 9, packing layer, etc. out of the drying bed, and the spare drying bed wall 9, packing layer, etc. can be pushed into the drying bed to complete the rapid replacement of the main part of the drying module, ensuring the drying effect and the continuity of use of the drying bed. The replaced drying bed wall 9, air distribution mechanism, packing layer, etc. can be repaired and cleaned for standby for the next maintenance and repair of the drying bed. This not only shortens the maintenance time and the equipment shutdown time, but also improves the maintenance efficiency and reduces the labor intensity.

[0057] Optionally, a notch is provided on the inner wall of the tower body 3, and the notch is arranged opposite to the maintenance opening. The drying module can be embedded at the notch. Embedding the drying module at the notch increases the integrity inside the drying bed. The sealing plate 10 is arranged on the tray 7. When the tray 7 moves, it can carry the sealing plate 10 to move synchronously, and then the sealing plate 10 is used to open and close the maintenance opening to ensure the overall sealing of the tower body 3, without the need for manual opening and closing of the maintenance opening, and at the same time improving the operation fluency.

[0058] Optionally, a grille plate 2 is provided at the air outlet 1. The grille plate 2 does not block the airflow from carrying powder impurities through, and at the same time the grille plate 2 can provide a filtering function to prevent the packing from detaching or large impurities from passing through and entering the air.

[0059] As can be seen from the above description and practice, compared with the prior art, the drying module and the drying device provided by the present application have the following advantages: When using the above drying module, during the daily maintenance of the drying bed, if problems such as fouling of inert particles and blockage of through holes occur, the driving mechanism can be started to move the drying bed wall, the packing layer, etc. out of the drying bed, and the spare drying bed wall, packing layer, etc. can be pushed into the drying bed to complete the rapid replacement of the main part of the drying module, ensuring the drying effect and the continuity of use of the drying bed. The replaced drying bed wall, packing layer, etc. can be repaired and cleaned for standby for the next maintenance and repair of the drying bed. This not only shortens the maintenance time and the equipment shutdown time, but also improves the maintenance efficiency and reduces the labor intensity.
