Description

Technical Field

[0001] This utility model relates to the field of chemical engineering and technology, and more specifically to a circulating heating chamber cleaning device. Background Technology

[0002] The vacuum salt production workshop of China Salt Yulin adopts the gypsum seed crystal method. Because the calcium ions in the brine are not completely purified, they tend to adhere to the heating titanium tubes when the evaporator is heated. As the operating time increases, scaling and pipe blockage occur in the heating chamber, which seriously affects the heat exchange efficiency.

[0003] There are currently two methods for treating calcium sulfate scale: physical removal and chemical removal. Physical removal uses a high-pressure water gun to agitate the scale layer, causing it to detach and achieving the desired descaling effect. However, this method is rarely used nowadays due to certain safety risks during operation and the potential damage to the titanium tubes in the heating chamber caused by the high-pressure environment. Three common chemical descaling methods are: First, boiling the tank with a soda ash solution followed by acid cleaning, repeating this process until the scale is completely removed; second, adding high-concentration hydrochloric acid and heating to 90-100℃; both of these methods require heating and acid addition, which may cause irreversible acid corrosion to the titanium tubes in the heating chamber. The third method uses a suitable calcium sulfate cleaning agent, which achieves the descaling purpose without damaging the equipment. Comparatively, the third method is more suitable for the conditions in our workshop.

[0004] Therefore, in view of the existing problems, how to provide a circulating heating chamber cleaning device that can improve cleaning efficiency, and enhance system stability and equipment protection through sedimentation separation design and cleaning fluid recycling, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides a circulating heating chamber cleaning device, which can improve cleaning efficiency, and at the same time enhances the stability of the system and equipment protection through sedimentation separation design and recycling of cleaning fluid.

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

[0007] A circulating heating chamber cleaning device, comprising:

[0008] A cleaning tank, wherein a water inlet is provided at the top of the cleaning tank and a water outlet is provided at the bottom of the cleaning tank;

[0009] A circulation pipe, the first end of which is connected to the outlet of the cleaning tank;

[0010] The settling tank has its inlet end connected to the circulation pipe and located near the second end of the circulation pipe; the cleaning liquid outlet end of the settling tank is located near the first end of the circulation pipe and is connected to the inlet of the cleaning tank through the cleaning liquid pipe; the sediment outlet end of the settling tank is located on the same side as the inlet end of the settling tank.

[0011] A control valve assembly is installed on the connecting pipeline between the cleaning tank, the circulation pipe, and the settling tank. The control valve assembly is used to receive control terminal signals to realize the opening and closing of the control valve assembly.

[0012] Through the above technical solution, this utility model provides a circulating heating chamber cleaning device. The cleaning fluid in the cleaning tank enters the circulation pipe through the outlet and is then transported to the settling tank. The settled cleaning fluid flows back from the cleaning fluid outlet to the cleaning tank inlet through the cleaning fluid pipe, forming a complete circulation loop. This eliminates the need for frequent replacement of the cleaning fluid, significantly reducing cleaning agent consumption and procurement costs; it also reduces the amount of waste cleaning fluid discharged, alleviating the environmental burden. The inlet and outlet of the settling tank are designed on the same side, facilitating rapid settling of the sediment under gravity after the entry of the scale-containing cleaning fluid, and preventing sediment from flowing back into the cleaning tank with the cleaning fluid. The control valve assembly can receive signals from the control terminal to precisely control the opening and closing of the connecting pipes between the cleaning tank, circulation pipe, and settling tank. It can adjust the fluid flow rate and circulation rhythm according to the cleaning progress, preventing sediment from clogging the pipes or flowing back into the cleaning tank, thus affecting the cleaning effect. It also prevents abnormal cleaning fluid flow rate from causing impact damage to the heating chamber equipment, ensuring a stable cleaning process without additional damage to the equipment. The circulating cleaning mode allows the cleaning fluid to continuously act on the parts to be cleaned. Compared with single static cleaning, it can more fully contact and react with the scale layer, accelerating the dissolution and removal of the scale layer. Moreover, the cleaning process can be flexibly controlled through the control valve component, eliminating the need for frequent manual operation and reducing efficiency loss caused by human intervention. It is suitable for the continuous and efficient cleaning needs in industrial scenarios such as the vacuum salt production workshop of China Salt Yulin.

[0013] Preferably, in the above-mentioned circulating heating chamber cleaning device, the settling tank further includes an overflow baffle. The overflow baffle is located in the inner cavity of the settling tank and its surface is parallel to the side plate of the settling tank. The top of the overflow baffle has a reserved gap with the inner top wall of the settling tank. The overflow baffle divides the settling tank into a clear liquid tank and a sedimentation tank. The clear liquid tank is close to the first end of the circulation pipe. The cleaning liquid outlet is located at the bottom of the side wall of the clear liquid tank. The sediment outlet is located at the bottom of the side wall of the sedimentation tank. The inlet is located at the top of the side wall of the sedimentation tank.

[0014] The beneficial effects of this invention are as follows: The overflow baffle clearly divides the settling tank into a settling tank and a clear liquid tank. The scale-containing cleaning solution enters from the inlet end at the top of the side wall of the settling tank, allowing sufficient space and time for settling. The sediment settles to the bottom of the settling tank due to gravity and can be completely discharged from the sediment outlet end at the bottom of the side wall. The upper layer of clean cleaning solution overflows into the clear liquid tank through the reserved gap between the top of the overflow baffle and the inner top wall, preventing insufficiently settled impurities from entering the clear liquid tank. This ensures that the cleaning solution flowing out from the cleaning solution outlet end at the bottom of the side wall of the clear liquid tank has higher purity and maintains good cleaning ability after returning to the cleaning tank, further improving the cleaning effect on the scale layer in the heating chamber. At the same time, the physical separation of the settling tank and the clear liquid tank allows operators to selectively clean the sediment in the settling tank and monitor the status of the cleaning solution in the clear liquid tank without having to operate the entire settling tank, reducing maintenance difficulty, minimizing maintenance downtime, and ensuring continuous operation of the cleaning system.

[0015] Preferably, in the above-mentioned circulating heating chamber cleaning device, the settling tank further includes settling plates, and the number of settling plates is multiple and divided into two groups, with each group of settling plates being arranged obliquely on the inner side wall of the sedimentation tank.

[0016] The beneficial effects of this invention are as follows: The inclined settling plates form a multi-layered interception structure within the sedimentation tank. After the scale-laden cleaning solution enters the sedimentation tank from the inlet, its flow path is extended due to the obstruction of the settling plates, increasing the residence time of the cleaning solution in the sedimentation tank. This allows sufficient time for precipitates such as calcium sulfate to separate from the cleaning solution and adhere to the surface of the settling plates or sink to the bottom of the tank, significantly improving the settling speed and thoroughness, reducing the impurity content entering the clear liquid tank, and further ensuring the cleanliness of the returned cleaning solution. Furthermore, the layered design of the settling plates creates more settling areas within the limited space of the sedimentation tank, effectively expanding the settling area. This eliminates the need to increase the overall size of the sedimentation tank to improve the settling effect, saving equipment installation space. It is particularly suitable for industrial sites with limited space, such as the vacuum salt production workshop of China Salt Yulin, reducing the difficulty of equipment layout.

[0017] Preferably, the above-mentioned circulating heating chamber cleaning device further includes a cleaning fluid overflow pipe. The top of the side wall of the cleaning fluid tank is provided with a cleaning fluid overflow port. One end of the cleaning fluid overflow pipe is connected to the cleaning fluid overflow port, and the other end is connected to the circulating pipe near the first end.

[0018] The beneficial effects of this invention are as follows: When the cleaning fluid level in the clearing tank is too high, some of the cleaning fluid can enter the overflow pipe through the overflow outlet, then flow back to the first end of the circulation pipe, where it merges with the cleaning fluid in the circulation pipe and re-enters the subsequent circulation. This avoids waste and environmental pollution caused by the cleaning fluid overflowing from the settling tank due to excessively high levels in the clearing tank. It also replenishes the fluid flow in the circulation pipe, ensuring a stable total amount of cleaning fluid in the entire circulation system, preventing fluctuations in flow rate from affecting the cleaning effect in the cleaning tank, and guaranteeing the safety and stability of the system operation. Furthermore, if the concentration of the cleaning fluid in the clearing tank decreases slightly due to long-term circulation, it can be mixed with the cleaning fluid flowing out of the cleaning tank (which may still contain some effective components) after flowing back through the overflow pipe. This balances the overall cleaning fluid concentration to some extent, slows down the rate of cleaning fluid failure, indirectly extends the service life of the cleaning fluid, and reduces the frequency of cleaning agent replenishment.

[0019] Preferably, the above-mentioned circulating heating chamber cleaning device further includes a cleaning agent replenishment pipe, which is connected to the cleaning liquid pipe.

[0020] The beneficial effects of this invention are as follows: As the cleaning process progresses, the effective components in the cleaning solution are gradually consumed due to reaction with the scale layer, resulting in a decrease in concentration and a weakening of the cleaning effect. New cleaning agent can be directly added to the cleaning solution via the cleaning agent replenishment pipe, rapidly increasing the cleaning solution concentration and ensuring that the cleaning solution returning to the cleaning tank always maintains high-efficiency cleaning capability. This avoids cleaning interruptions or incomplete cleaning due to cleaning solution failure, ensuring continuous removal of calcium sulfate scale from the heating chamber. Operators can also flexibly adjust the replenishment amount and timing by controlling the valve opening and flow rate of the cleaning agent replenishment pipe based on the cleaning solution concentration test results or cleaning effect feedback, without stopping the entire circulation system. This adapts to the dynamic needs of different stages during the cleaning process, ensuring the stability of cleaning efficiency and effect.

[0021] Preferably, the above-mentioned circulating heating chamber cleaning device further includes a cleaning component located at the top of the cleaning tank. The cleaning component includes a cleaning pipe and nozzles. The sidewall of the cleaning pipe is provided with a plurality of through holes evenly distributed along its length, and the water inlet end of the cleaning pipe is fixed and penetrates the sidewall of the cleaning tank. The number of nozzles is plurality of and they are fixed on the sidewall of the cleaning pipe corresponding to the through holes.

[0022] The beneficial effects of this invention are as follows: the cleaning pipe introduces cleaning fluid through the inlet and delivers it to each nozzle through evenly distributed through-holes along its length. The nozzles spray the cleaning fluid at high pressure or a specific angle, providing comprehensive coverage and rinsing of the components to be cleaned within the cleaning tank. Compared to traditional immersion cleaning or unidirectional rinsing, this method acts more directly and evenly on the surface of the scale, accelerating the dissolution and removal of the scale. It is particularly effective for areas prone to scaling and difficult to clean, such as the outer wall of heated titanium tubes, significantly improving cleaning thoroughness and reducing scale residue.

[0023] Preferably, the above-mentioned circulating heating chamber cleaning device further includes a heating component, which is fixed inside the cleaning tank.

[0024] The beneficial effects of this invention are: the heating component acts only on the cleaning liquid in the cleaning tank and can be used in conjunction with a third safe cleaning agent. At the same time, through precise temperature control, it can not only meet the temperature requirements of the cleaning reaction, but also avoid irreversible corrosion of equipment such as titanium tubes in the heating chamber due to improper heating method or temperature runaway, thus balancing cleaning efficiency and equipment protection.

[0025] Preferably, in the above-mentioned circulating heating chamber cleaning device, the horizontal height of the settling tank is higher than the horizontal height of the circulating pipe.

[0026] The beneficial effects of this invention are: it makes the fluid flow more stable, avoids sudden changes in fluid velocity caused by pressure fluctuations in power equipment, and reduces the probability of deposits in the scale-containing cleaning fluid adhering to the inner wall of the circulation pipe; at the same time, the stable flow state also helps the deposits in the settling tank to settle evenly, further reducing the risk of pipeline blockage and ensuring the long-term stable operation of the entire circulation system.

[0027] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a circulating heating chamber cleaning device, which has the following beneficial effects:

[0028] 1. This utility model utilizes a circulation loop consisting of a cleaning tank, a circulation pipe, and a settling tank. After the cleaning solution is used in the cleaning tank, it enters the settling tank through the circulation pipe for purification, and then flows back to the cleaning tank for reuse. This eliminates the need for frequent replacement of the solution, significantly reducing the amount of cleaning agent required and minimizing resource waste. Simultaneously, the circulation model reduces the generation and discharge of waste cleaning solution, lowering the cost and difficulty of subsequent environmental treatment, and meeting the requirements of green and sustainable industrial production.

[0029] 2. The settling tank of this utility model is divided into a sedimentation tank and a clear liquid tank by an overflow baffle. Combined with the top inlet and bottom slag discharge layout, the scale-containing cleaning solution is allowed to fully settle in the sedimentation tank, with impurities discharged from the bottom. The cleaning solution overflows into the clear liquid tank for return, preventing impurities from affecting the cleaning effect. Furthermore, multiple sets of inclined settling plates extend the flow path and residence time of the scale-containing cleaning solution in the sedimentation tank, accelerating impurity settling and further improving the cleaning solution purification efficiency. At the same time, there is no need to increase the volume of the settling tank, saving installation space. Meanwhile, the cleaning solution overflow pipe at the top of the clear liquid tank can return excess cleaning solution to the circulation pipe, preventing clear liquid overflow and waste, maintaining flow balance within the circulation system, and avoiding the cleaning process being affected by abnormal liquid levels.

[0030] 3. This utility model physically separates the sedimentation tank and the clear liquid tank within the settling box. Operators can selectively clean impurities in the sedimentation tank and monitor the status of the clear liquid tank without disassembling the entire device, reducing maintenance time and workload. It also allows for direct connection between the cleaning agent replenishment pipe and the cleaning liquid pipe, enabling real-time replenishment of the agent based on the cleaning liquid concentration without stopping the circulation system. This ensures the cleaning liquid maintains consistently high cleaning efficiency, adapting to the needs of different cleaning stages. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] See appendix Figure 1 This utility model discloses a circulating heating chamber cleaning device, including: a cleaning tank 1, a circulation pipe 2, a settling tank 3, and a control valve assembly;

[0038] The cleaning tank 1 has an inlet at the top and an outlet at the bottom. The first end of the circulation pipe 2 is connected to the outlet of the cleaning tank 1. The inlet of the settling tank 3 is connected to the circulation pipe 2 and is located near the second end of the circulation pipe 2. The cleaning liquid outlet of the settling tank 3 is located near the first end of the circulation pipe 2 and is connected to the inlet of the cleaning tank 1 through the cleaning liquid pipe 4. The sediment outlet of the settling tank 3 is located on the same side as the inlet of the settling tank 3. The control valve assembly is installed on the connecting pipeline between the cleaning tank 1, the circulation pipe 2 and the settling tank 3. The control valve assembly is used to receive signals from the control end to realize the opening and closing of the control valve assembly.

[0039] Specifically, it also includes a plaster jar 8, with a plaster jar drain pipe 81 fixed at the bottom of the plaster jar 8, and the second end of the circulation pipe 2 connected to the plaster jar drain pipe 81.

[0040] In some embodiments, the inlet end of the settling tank 3 is connected to the circulation pipe 2 through the first pipeline 37, and a sixth valve 38 is provided on the first pipeline 37.

[0041] In some specific embodiments, the settling tank 3 also includes an overflow baffle 31. The overflow baffle 31 is located in the inner cavity of the settling tank 3 and its surface is parallel to the side plate of the settling tank 3. The top of the overflow baffle 31 has a reserved gap with the inner top wall of the settling tank 3. The overflow baffle 31 divides the settling tank 3 into a clear liquid tank 32 and a sedimentation tank 33. The clear liquid tank 32 is close to the first end of the circulation pipe 2. The cleaning liquid outlet is opened at the bottom of the side wall of the clear liquid tank 32, the sediment outlet is opened at the bottom of the side wall of the sedimentation tank 33, and the inlet is opened at the top of the side wall of the sedimentation tank 33.

[0042] Specifically, the outlet end of the sediment is connected to a discharge pipe 35, and a first valve 36 is installed on the discharge pipe 35.

[0043] More specifically, it also includes a waste liquid collection pipe 10, one end of which is connected to the cleaning liquid pipe 4, and the other end is connected to the discharge pipe 35. A second valve 101 is installed on the waste liquid collection pipe 10. At the same time, a fourth valve 41 is also installed at the position where the cleaning liquid pipe 4 connects to the waste liquid collection pipe 10.

[0044] In some other examples, the settling tank 3 also includes settling plates 34, which are multiple and divided into two groups, with each group of settling plates 34 being arranged obliquely on the inner wall of the sedimentation tank 33.

[0045] In a specific embodiment, it also includes a cleaning fluid overflow pipe 5. A cleaning fluid overflow port is provided at the top of the side wall of the cleaning fluid tank 32. One end of the cleaning fluid overflow pipe 5 is connected to the cleaning fluid overflow port, and the other end is connected to the circulation pipe 2 near the first end.

[0046] In a specific example, a cleaning agent replenishment tube 6 is also included, which is connected to the cleaning fluid tube 4.

[0047] Specifically, a third valve 61 is installed on the cleaning agent replenishment pipe 6.

[0048] In some embodiments, a cleaning pump 9 is also included, which is connected to the cleaning fluid line 4 and located near the cleaning tank 1. This provides power for pumping the cleaning fluid and cleaning agent.

[0049] Specifically, a fifth valve 42 is installed at one end of the cleaning pump 9 and the cleaning liquid pipe 4 near the cleaning tank 1.

[0050] In one specific embodiment, the end of the cleaning fluid pipe 4 near the cleaning tank 1 is connected to a cleaning fluid collection pipe 43, and a seventh valve 44 is provided on the cleaning fluid collection pipe 43.

[0051] In some examples, a cleaning assembly 7 is also included, which is located at the top of the cleaning tank 1. The cleaning assembly 7 includes a cleaning pipe 71 and a nozzle 72. The side wall of the cleaning pipe 71 is provided with a plurality of through holes evenly distributed along its length, and the water inlet end of the cleaning pipe 71 is fixed and penetrates the side wall of the cleaning tank 1. There are multiple nozzles 72 and the corresponding through holes are fixed on the side wall of the cleaning pipe 71.

[0052] In some specific examples, a heating component is also included, which is fixed inside the cleaning tank 1.

[0053] In some other embodiments, the settling tank 3 is at a higher level than the circulation pipe 2.

[0054] The method of use and working principle of this utility model are as follows:

[0055] Before starting work, insert the cleaning pipe 71 and nozzle 72 into the corresponding blocked tubes, open the fifth valve 42, close the seventh valve 44, open the fourth valve 41, close the third valve 61, connect the cleaning agent replenishment pipe 6 to the calcium sulfate special cleaning agent storage tank, close the second valve 101, adjust the position of the settling tank 3 and the circulation pipe 2 so that their elevations are the same, close the top cover of the settling tank 3, open the sixth valve 38, and close the first valve 36.

[0056] After the cleaning fluid replenishment pipe 6 is filled with liquid, the cleaning pump 9 is started. The calcium sulfate-specific cleaning agent, after being energized by the cleaning pump 9, enters the cleaning tank 1 at a pressure of 0.15-0.2 MPa through the cleaning fluid pipe 4, cleaning pipe 71, and nozzle 72 to clean the tubes to be unclogged in the cleaning tank. After one hour of reaction between the scale and the cleaning agent, the scale thickness is reduced by 3 mm. After 24 hours of reaction, the scale is completely dissolved. Cleaning one tube only takes 18-24 hours. The dissolved mixed liquid flows into the circulation pipe 2 by gravity, and enters the sedimentation tank 33 through the first pipeline 37 and the sixth valve 38. It settles on the settling plate 34 and overflows to the clear liquid tank 32 through the overflow baffle 31. The cleaning fluid overflow pipe 5 is set in this area. In this way, the cleaning fluid from the cleaning fluid pipe 4, the cleaning tank 1, the circulation pipe 2, and the settling tank 3 forms a repeated circulation system.

[0057] When the calcium sulfate cleaning agent solution appears milky, it indicates that the cleaning agent has reached saturation and has lost its cleaning effect. Open the sixth valve 38, open the second valve 101, and close the first valve 36. The waste liquid in the clear liquid tank 32 enters the waste liquid collection pipe 10 and then enters the cleaning liquid pipe 4. After mixing with the waste liquid in the clear liquid tank 32, it is transferred to the outside of this system through the cleaning liquid collection pipe 43. When the liquid level in the settling tank 3 reaches 10% to 20%, replenish the calcium sulfate cleaning agent according to the above method.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
