[0028] Figure 2 A collection device of the cleaning device according to a first embodiment of the present invention is shown;

[0031] In order to make the technical solutions and advantages of the present invention clearer and more understandable, the exemplary embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than an exhaustive list of all embodiments. And without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0032] An embodiment of the present invention provides a cleaning device. As Figure 1 shown, the cleaning device includes a water source 1, a high-pressure water jet booster device 2, a high-pressure flexible pipe 3, a collection device 4, and a recycler 5. Among them, the water source 1 is mainly used to provide water to meet the usage requirements of cleaning. The high-pressure water jet booster device 2 is communicatively arranged with the water source 1 and is mainly used to pressurize the water so that the water jets out as a high-pressure water jet. The high-pressure flexible pipe 3 is arranged at the outlet of the high-pressure water jet booster device 2 and is used to receive the high-pressure water. At the same time, the high-pressure flexible pipe 3 guides the high-pressure water to the chemical equipment or pipeline to be cleaned (indicated by reference numeral 200 in the figure) to clean the chemical equipment or pipeline. The collection device 4 is used to collect the waste mixed liquid after cleaning to prevent the waste mixed liquid after cleaning from flowing everywhere and polluting the environment. The recycler 5 is arranged downstream of the collection device 4 and is used to store the waste mixed liquid after cleaning.

[0033] Thus, on the one hand, the cleaning device uses a high-pressure water jet booster device 2 to pressurize water, so that the water flow is ejected at a high speed after obtaining huge energy. The water flow with highly concentrated energy has a large impact kinetic energy. When it hits the surface of the object to be cleaned, it will use its impact force, grinding effect, etc. to make the coke deposits, dirt and attachments detach from the surface of the object to be cleaned, completing the cleaning of the pipeline or equipment. This cleaning method ensures high cleaning efficiency and more thorough cleaning. On the other hand, the cleaning device is equipped with a collection device 4 and a recycler 5, which can collect and store the mixture after cleaning, preventing the cleaning liquid from flowing everywhere, ensuring that the equipment and the ground are clean and tidy, and avoiding environmental pollution.

[0034] According to the present application, the high-pressure water jet booster device 2 can be an equipment in the prior art, for example, an increasing pump. During use, according to the self-bearing capacity and pollution degree of the product to be cleaned, the pressure of the cleaning liquid is adjusted. For example, after passing through the high-pressure water jet booster device 2, the water pressure can be increased to 1200 - 3200 bar. Of course, according to the actual situation, the water pressure can also be increased or decreased. The high-pressure flexible pipe 3 is convenient for transporting high-pressure water. At the same time, the high-pressure flexible pipe 3 can be arranged and bent arbitrarily, and can easily bypass obstacles such as platforms, pipelines and labor protection, and can be conveniently applied even in complex scenarios. According to needs, a spray gun or the like can also be provided at the outlet of the high-pressure flexible pipe 3 to facilitate the spraying of the water flow.

[0035] As Figure 2 shown, the collection device 4 has a collection device main body 41, a drainage inlet 42 and a drainage outlet 43. Among them, the collection device main body 41 is in the shape of a container and is used to collect the cleaning liquid after cleaning. The drainage inlet 42 is arranged on the collection device main body and is connected to the equipment and pipeline to be cleaned, serving as the inlet for collecting the cleaning liquid after cleaning. The drainage outlet 43 is arranged on the collection device main body 41. At the same time, the drainage outlet 43 is connected to the recycler 5 in a communicating manner, and is used to transport the cleaning liquid after cleaning to the recycler 5. According to the present application, a first filter screen 44 is provided at the drainage outlet 43, which is used to filter the cleaning liquid passing through the drainage outlet 43 to leave the solid waste in the collection device main body 41.

[0036] Preferably, the bottom wall of the collection device main body 41 is configured as a slope, and the discharge port 43 is located at the lowest point of the bottom wall of the collection device main body 41. In a specific embodiment, the collection device main body 41 is configured as a semi-cylindrical body, and the discharge port 43 is arranged on the arc-shaped bottom wall. The shapes and installation positions of the collection device main body 41 and the inlet 42 can be adjusted according to the docking device. For example, in order to dock with a pipeline, the collection device main body 41 is configured as a semi-cylindrical body, and the inlet 42 can be formed by a semi-circular plate 45, and bolts 46 are arranged on the semi-circular plate 45 to be connected to the flange of the pipeline through the bolts 46. This way can enable the collection device 4 to be well docked to the pipeline to be cleaned, avoiding water leakage. In addition, the above structure can ensure that the collection device 4 can be conveniently connected or disassembled from the pipeline to be cleaned.

[0037] A first slag discharge door 47 is arranged on the side wall of the collection device main body 41. The first slag discharge door 47 is used to facilitate slag cleaning. When a certain amount of solid waste accumulates in the collection device main body 41, the first slag discharge door 47 is opened to clean the solid waste, which is convenient for operation. A first handle 48 is arranged on the first slag discharge door 47 to facilitate the application of force.

[0038] Generally, the pipeline and equipment layout of chemical plants is relatively compact, the space is relatively narrow and most of the positions are not on the ground, and the discharge and recovery of the waste mixed liquid generated during the high-pressure water jet cleaning process are relatively difficult. Existing mechanical cleaning, etc. do not have effective waste mixed liquid recovery facilities. The main methods include draining to the ground for recovery through a large-diameter plastic sheet, or placing a water receiving tank under the cleaning port for recovery, etc. During the cleaning process, the waste liquid flows along the surface of the pipeline or the equipment body and cannot be completely recovered, and the solid waste generated during the cleaning process cannot be cleaned in time, which is likely to cause problems such as plastic sheet rupture and sewage discharge port blockage, seriously affecting the cleaning progress and easily causing environmental pollution accidents. The cleaning equipment of the present application can better collect the waste liquid through the collection device 4 to achieve environmental protection and recovery.

[0039] An oil-water separation device 6 for oil-water separation is arranged between the collection device 4 and the recycler 5. As Figure 3 and 4As shown, the oil-water separation device 6 includes a plurality of storage tanks 61, overflow plates 62 disposed between adjacent storage tanks 61, and connecting pipes 63 communicatively disposed with each storage tank 61. Among them, a water outlet 64 is provided at the bottom end of each storage tank 61. The connecting pipe 63 is vertically arranged and communicated with the corresponding water outlet 64, functioning as a communicating vessel. At the same time, the downstream of the connecting pipe 63 is communicated with the recycler 5. The height of each overflow plate 62 is at the same level as the center of the outlet at the higher downstream end of the corresponding connecting pipe 63. During operation, the uppermost upstream storage tank 61 receives the cleaning liquid from the collection device 4. Inside the storage tank 61, the water with a higher density is at the lower end and the oil with a relatively lower density is at the top. The water enters the connecting pipe 63 through the water outlet 64. As the cleaning liquid in the storage tank 61 increases, the liquid level in the connecting pipe 63 also increases accordingly. When the liquid in the connecting pipe 63 reaches the outlet at the high end, as the cleaning liquid continues to be injected, the water is discharged outwards through the outlet at the high end of the connecting pipe 63. As the liquid level of the cleaning liquid in the storage tank 61 further rises, the oil flows through the overflow plate 62 into the next storage tank 61. Thus, the water-oil separation of the cleaning liquid in this storage tank 61 is completed. The next storage tank 61 accumulates the cleaning liquid, and the water and oil are separated according to the same working principle. A water delivery pipe 65 is communicatively provided at the outlet at the high end of the water in each connecting pipe 63, and this water delivery pipe 65 is used to deliver the separated water to the recycler 5. And an oil delivery pipe 66 is inserted on the wall near the upper edge of the lowermost downstream storage tank 61, for guiding the separated oil out.

[0040] For example, the height of each overflow plate 62 is at the same level as the center of the outlet at the high end of the corresponding connecting pipe 63. In Figure 4 the illustrated embodiment, in the uppermost upstream storage tank 61, when the liquid level in the storage tank 61 reaches h1, as the cleaning liquid continues to be injected, the water flows into the water delivery pipe 65 through the outlet at the high end of the connecting pipe 63. And when the liquid level in the storage tank 61 reaches h1', as the liquid continues to be injected into the storage tank 61, the oil in the cleaning liquid flows through the corresponding overflow plate 62 into the next-level storage tank 61. According to actual needs, multiple storage tanks 61 can be provided, for example, seven, eight, nine, ten or more.

[0041] During manufacturing, a trapezoidal tank can be produced first, where the height of the upstream end is higher than that of the downstream end. A plurality of partitions perpendicular to the upstream and downstream directions are provided inside the trapezoidal tank for dividing the trapezoidal tank into a plurality of storage tanks 61. Among them, the partitions can act as the overflow plates 62. And the connecting pipe 63 is arranged on the outer wall of the trapezoidal tank and is tubular itself. For convenient delivery, a connecting pipe 67 can be provided between the high-end outlet of the connecting pipe 63 and the water delivery pipe 65. This connecting pipe 67 extends in the up and down direction to deliver the liquid in the connecting pipe 63 into the water delivery pipe 65.

[0042] This application is provided with an oil-water separation device 6, and the oil-water separation device 6 uses principles and properties such as the communicating vessel principle, the difference in oil-water liquid columns, and the different oil-water densities to perform multi-stage cutting and separation of oil and water in the waste mixed liquid, achieving efficient separation, recycling, and classified recovery of oil, water, and solids.

[0043] There are at least two parallel accommodation tanks 7 provided between the collection device 4 and the oil-water separation device 6. A second filter screen 71 is provided between the accommodation tank 7 and the oil-water separation device 6. Structurally, the storage tank 7 can be seated on the trapezoidal groove of the storage tank 61, adjacent to the uppermost upstream storage tank 61. According to this application, the cleaning liquid filtered by the collection device 4 enters the accommodation tank 7, and then is further filtered through the second filter screen 71, and then the cleaning liquid is transported into the uppermost upstream storage tank 61. It can be seen that this cleaning equipment can perform two-stage filtering to improve the filtering efficiency. This filtering method can reduce the working pressure of the first filter screen 44 and achieve hierarchical filtering. The accommodation tank 7 can be constructed as a square box body with an open upper end for receiving the cleaning liquid. The second filter screen 71 is inclinedly arranged in the accommodation tank 7 to divide the inner cavity of the accommodation tank 7 into an upper space 72 and a lower space 73. A second slag discharge door 74 is provided on the wall of the upper space 72 for slag removal operations. A second handrail 75 is provided on the second slag discharge door 74 to facilitate operations such as opening or closing the second slag discharge door 74.

[0044] Multiple accommodation tanks 7 can be provided, for example, two. These two accommodation tanks 7 are arranged in parallel. During the cleaning process, one of them can be selected for use. When slag removal operations are required, this accommodation tank 7 enters a non-working state, while the other accommodation tank 7 enters a working state, which can ensure that the cleaning work is uninterrupted. Of course, two or more accommodation tanks 7 can work simultaneously. For example, the discharge port 43 of the collection device can be connected to the accommodation tank 7 through a connecting hose 8. This connecting hose 8 can well adapt to the environment and meet the usage requirements.

[0045] The recycler 5 is connected to the water source and is in the shape of a container, such as a box. That is to say, the water separated by the oil-water filtration device 6 is stored in the recycler 5 for recycling to save water resources. In this application, the water source and the recycler 5 can share the same container.

[0046] The following is based on Figures 1 to 4 to detail the working process of the cleaning equipment of this application.

[0047] First, clean water is injected into the recycler 5.

[0048] Then, the high-pressure water jet booster device 2 is started. The high-pressure flexible pipe 3 receives the high-pressure water and guides the high-pressure water to the chemical equipment or pipeline to be cleaned to clean the chemical equipment or pipeline.

[0049] As the cleaning progresses, the waste liquid after cleaning enters the main body 41 of the collection device through the discharge port 42. Coarse filtration is carried out through the first filter screen 44, and relatively large solid wastes remain in the main body 41 of the collection device. When the relatively large solid wastes accumulate to a certain extent in the main body 41 of the collection device, the main body 41 of the collection device can be cleaned. It can be understood that during the cleaning operation, the high-pressure water jet boosting device 2 can be stopped to suspend the cleaning.

[0050] The waste liquid passing through the first filter screen 44 enters the connecting hose 8 through the discharge port 43 and is transported by the connecting hose 8 to the receiving tank 7. In the receiving tank 7, the waste liquid is further filtered more finely through the second filter screen 71. The filtered waste liquid enters the oil-water separation device 6 for oil-water separation. The separated water is sent to the recycler 5 through the water delivery pipe 65 for further recycling. The separated oil is guided out through the oil delivery pipe 66 for final collection to avoid environmental pollution. Among them, in the receiving tank 7, if the solid residues in the upper space 72 accumulate to a certain extent, the second slag discharge door 74 can be opened to clean in time. It can be understood that during the operation of cleaning the solid residues, the receiving tank 7 can be used replaceably, or the cleaning operation can be directly suspended.

[0051] Thus, the cleaning equipment of the present application realizes the full recovery of the high-pressure water jet cleaning waste mixture. The flexible hose can bypass obstacles such as platforms, pipelines, and labor protection, facilitating the layout of the cleaning equipment. By using multi-stage filtration, combined with principles and properties such as the principle of communicating vessels, the difference in oil-water liquid columns, and different oil-water densities, the oil and water in the waste mixture are cut and separated in multiple stages, realizing the efficient separation of oil, water, and solids. The cleaning equipment of the present application achieves the effects of efficient cleaning, environmental protection recovery, recycling, and classified disposal, solves the problem of the recovery and disposal of the high-pressure water jet cleaning waste mixture, and avoids environmental pollution accidents.

[0052] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and / or modifications falling within the scope of the present invention.
