Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sludge conditioning, and in particular to a sludge precise conditioning system. BACKGROUND

[0002] Sludge dewatering refers to a process of removing most of the water content from sludge, which can effectively reduce the volume and quantity of sludge, improve the treatment efficiency and quality of sludge, and also help protect the environment and human health. A sludge dewatering system is usually composed of a residue removal system, a concentration system, a conditioning system and a dewatering system. Sludge is transported to the residue removal system through a pipeline, and after the removal of large-particle residues and scum, the sludge is transported to the concentration system for concentration adjustment. The slurry with adjusted concentration is transported to the conditioning system, where materials are added to condition and adjust the slurry, change the internal microstructure of the slurry, and quickly improve the subsequent dewatering and solidification effect. Finally, the conditioned slurry is transported to the dewatering system to separate water and sludge cake.

[0003] For the related art in the above, the conditioning system using a single medicament often needs workers to add medicaments for multiple times in order to test the best conditioning effect when aiming at different sludge types. However, during the medicament adding process, the medicament adding amount is uncertain, which easily leads to the problem that it is difficult to accurately condition. CONTENT OF THE INVENTION

[0004] In order to facilitate the realization of accurate conditioning function, the application provides a sludge precise conditioning system.

[0005] The sludge precise conditioning system provided by the application adopts the following technical scheme:

[0006] A sludge precise conditioning system comprises:

[0007] a sludge path module;

[0008] a medicament path module;

[0009] an online water content measuring instrument module comprising a concentration meter, a first flow meter and a second flow meter, wherein the concentration meter and the first flow meter are arranged on the sludge path module, and the second flow meter is arranged on the medicament path module; the concentration meter is used for detecting the concentration of sludge transported by the sludge path module; the first flow meter is used for detecting the amount of sludge transported by the sludge path module; and the second flow meter is used for detecting the amount of medicament transported by the medicament path module.

[0010] By adopting the technical scheme, when the sludge path module transports sludge, the concentration meter can detect the concentration of the sludge, and the first flow meter can detect the amount of sludge, so that the required amount of medicament can be calculated, and the second flow meter can detect the amount of medicament transported by the medicament path module, so as to accurately control the amount of medicament transported by the medicament path module, thereby reducing the possibility of too much or too little medicament being transported, and realizing accurate conditioning function.

[0011] Optionally, a pipeline mixer is arranged and communicates with the sludge path module and the medicament path module, and the pipeline mixer is used for uniformly mixing the sludge and the medicament.

[0012] By adopting the technical scheme, the sludge path module can transport sludge into the pipeline mixer, and the medicament path module can transport medicament into the pipeline mixer, so that the sludge and the medicament can be uniformly mixed in the pipeline mixer.

[0013] Optionally, the sludge path module comprises a sludge path pipeline, a sludge adding pump and a sludge path valve, one end of the sludge path pipeline is a sludge inlet end, the other end of the sludge path pipeline is a sludge outlet end, the sludge outlet end communicates with the pipeline mixer, the sludge adding pump, the sludge path valve, the concentration meter and the first flow meter are respectively arranged on the sludge path pipeline, the concentration meter and the first flow meter are located on the side of the sludge adding pump close to the sludge outlet end, and the concentration meter and the first flow meter are sequentially arranged along the direction from the sludge inlet end to the sludge outlet end.

[0014] By adopting the technical scheme, when it is needed to transport sludge into the pipeline mixer, the sludge path valve is opened, and the sludge adding pump works, so that the sludge is transported from the sludge inlet end to the sludge outlet end, and in this process, the concentration meter can detect the concentration of the sludge after the sludge passes through the sludge adding pump, and the first flow meter can detect the flow of the sludge, so that the concentration and the amount of the sludge can be monitored in real time, and the sludge path valve can control the on-off of the sludge path pipeline, so that the amount of the sludge can be adjusted according to actual needs, to ensure the stability and controllability in the sludge treatment process.

[0015] Optionally, the medicament path module comprises a medicament storage tank, a first pipeline, a second pipeline and a third pipeline, the first pipeline communicates with the medicament storage tank, one end of the second pipeline and one end of the third pipeline respectively communicate with the first pipeline, the other end of the second pipeline and the other end of the third pipeline respectively communicate with the pipeline mixer, a medicament adding pump is arranged on the second pipeline and the third pipeline, and two second flow meters are arranged, one second flow meter is arranged on the second pipeline, and the other second flow meter is arranged on the third pipeline.

[0016] By adopting the above technical solution, when it is necessary to deliver chemicals into the pipeline mixer, the dosing pump operates, allowing the chemicals stored in the storage tank to enter the second or third pipeline through the first pipeline, and then enter the pipeline mixer through the second or third pipeline. During this process, the second flow meter can monitor the amount of chemicals delivered in real time, thus facilitating precise delivery of chemicals into the pipeline mixer, reducing waste, and minimizing the possibility of reduced conditioning effect. Furthermore, the second and third pipelines can deliver different chemicals separately, allowing for flexible adjustment of the proportions and combinations of different chemicals according to actual needs to achieve the best conditioning effect.

[0017] Optionally, the pipeline mixer includes a connecting part, a reducing part, and a mixing unit. At least two connecting parts are provided. The reducing part is disposed between adjacent connecting parts. The inner diameter of the reducing part is smaller than the inner diameter of the connecting part. A mixing channel is formed between the connecting part and the reducing part. The mixing unit is disposed in the mixing channel. The mud path module and the drug path module are respectively connected to the connecting parts.

[0018] By adopting the above technical solution, when sludge and reagents are transported into the mixing channel, the mixing unit can promote the mixing between sludge and reagents. The inner diameter of the variable diameter section is smaller than the inner diameter of the connecting section, so that when sludge and reagents enter the variable diameter section from the connecting section, they can be subjected to the squeezing force applied by the inner wall of the variable diameter section, so that sludge and reagents can be better mixed, thereby improving the mixing efficiency.

[0019] Optionally, the mixing unit includes alternating left and right spiral blades, the left and right spiral blades being respectively disposed within the mixing channel and adapted to the inner diameter design of the mixing channel.

[0020] By adopting the above technical solution, the alternating design of the left and right spiral blades allows the sludge and chemicals to be conveyed along the left and right spiral blades in the mixing channel, so as to continuously cut and disperse the sludge and chemicals, thereby facilitating the uniform mixing of sludge and chemicals.

[0021] Optionally, micropores are formed on the left and right helical plates respectively.

[0022] By adopting the above technical solution, the micropores allow sludge and chemicals to pass through the micropores when passing through the left-hand and right-hand helical plates, thereby further dispersing the sludge and chemicals and improving mixing efficiency.

[0023] Optionally, the system includes a housing and a control cabinet disposed within the housing. The mud path module, the chemical path module, and the online moisture content analyzer module are respectively disposed within the housing. The control cabinet is used to control the operation of the mud path module, the chemical path module, and the online moisture content analyzer module.

[0024] By adopting the above technical solution, the control cabinet, sludge path module, chemical path module, and online moisture content analyzer module are respectively installed inside the enclosure. This facilitates the protection of the control cabinet, sludge path module, chemical path module, and online moisture content analyzer module by using the enclosure. Furthermore, the control cabinet centrally manages the sludge path module, chemical path module, and online moisture content analyzer module, realizing integrated control of the sludge drying process, simplifying the operation process, and improving the ease of operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Through the cooperation of the sludge path module, the chemical path module, the concentration meter, the first flow meter and the second flow meter, it is convenient to detect the amount and concentration of the sludge being transported. The second flow meter can detect the dosage of the chemical agent delivered by the chemical agent module, thereby achieving precise control of the chemical agent dosing and improving the accuracy and efficiency of sludge conditioning.

[0027] 2. Through the cooperation of the connecting part, the variable diameter part and the mixing unit, the sludge and the agent can be subjected to the squeezing force applied by the inner wall of the variable diameter part when they enter the variable diameter part from the connecting part, which facilitates better mixing of the sludge and the agent and thus helps to improve the mixing efficiency.

[0028] 3. By separately housing the control cabinet, sludge path module, chemical path module, and online moisture content analyzer module within the enclosure, it is convenient to protect these modules using the enclosure. Furthermore, the centralized management of these modules through the control cabinet enables integrated control of the sludge drying process, simplifying the operation process and improving ease of use.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Example 1:

[0040] Reference Figures 1-3 A sludge precision conditioning system includes a housing 1, a control cabinet 2, a sludge path module 3, a chemical path module 4, an online moisture content analyzer module 5, and a pipeline mixer 6. The control cabinet 2, sludge path module 3, chemical path module 4, and online moisture content analyzer module 5 are all housed inside the housing 1, while the pipeline mixer 6 is located outside the housing 1. The sludge path module 3 is used to transport sludge, the chemical path module 4 is used to provide conditioning agents, and the online moisture content analyzer module 5 is used to monitor the sludge concentration, flow rate, and agent dosage in real time. In other embodiments, the pipeline mixer 6 may also be installed inside the housing 1.

[0041] Reference Figure 2 and Figure 3 The mud path module 3 includes a mud path pipe 31, a mud pump 32, and a mud path valve 33. The mud path pipe 31 is installed inside the housing 1, with one end of the mud path pipe 31 being the mud inlet end 311 and the other end being the mud outlet end 312. The mud inlet end 311 is used to connect with the thickening system, and the mud outlet end 312 is connected with the pipe mixer 6.

[0042] The mud pump 32 and the mud valve 33 are respectively installed on the mud pipeline 31. There are two mud valves 33, one mud valve 33 is located near the mud inlet end 311, and the other mud valve 33 is located near the mud outlet end 312. The mud valve 33 is used to control the opening and closing of the mud pipeline 31.

[0043] When sludge needs to be fed into the pipe mixer 6, the two sludge passage valves 33 open, and the sludge pump 32 operates, facilitating the delivery of sludge into the pipe mixer 6. When sludge does not need to be fed into the pipe mixer 6, the sludge pump 32 stops operating, and the two sludge passage valves 33 close, preventing further sludge delivery into the pipe mixer 6.

[0044] Reference Figure 2 and Figure 3 The drug delivery module 4 includes a drug storage tank 41, a first pipe 42, a second pipe 43, and a third pipe 44. The drug storage tank 41 is located outside the housing 1. The first pipe 42, the second pipe 43, and the third pipe 44 are installed inside the housing 1. One end of the first pipe 42 extends out of the housing 1 and is connected to the drug storage tank 41. One end of the second pipe 43 and the third pipe 44 are connected to the first pipe 42, and the other end of the second pipe 43 and the third pipe 44 are connected to the pipe mixer 6.

[0045] A dosing pump 45 is installed on the second pipe 43 and the third pipe 44 respectively, and a dosing valve 46 is installed on the second pipe 43 and the third pipe 44 respectively. The dosing valve 46 is located close to the dosing pump 45 and is used to control the opening and closing of the second pipe 43 and the third pipe 44.

[0046] When it is necessary to deliver the medicine into the pipeline mixer 6, the dosing valve 46 is opened and the dosing pump 45 is activated, so that the medicine stored in the storage tank 41 can enter the second pipeline 43 or the third pipeline 44 through the first pipeline 42, and then enter the pipeline mixer 6 through the second pipeline 43 or the third pipeline 44. The second pipeline 43 and the third pipeline 44 are designed to deliver different medicines respectively, so as to flexibly adjust the proportion and combination of different medicines according to actual needs to achieve the best conditioning effect.

[0047] Reference Figure 3The online moisture content analyzer module 5 includes a concentration meter 51, a first flow meter 52, and a second flow meter 53. The concentration meter 51 and the first flow meter 52 are respectively installed on the sludge pipeline 31. Both the concentration meter 51 and the first flow meter 52 are located on the side of the sludge pump 32 near the sludge outlet 312, and are sequentially distributed along the direction from the sludge inlet 311 to the sludge outlet 312. This facilitates the detection of sludge concentration using the concentration meter 51 and the detection of sludge quantity using the first flow meter 52.

[0048] There are two second flow meters 53. One second flow meter 53 is installed on the second pipe 43, and the other second flow meter 53 is installed on the third pipe 44. This makes it convenient to use the second flow meters 53 to monitor the amount of medicine delivered in real time, thereby reducing the waste of medicine and the possibility of reduced conditioning effect.

[0049] Control cabinet 2 is electrically connected to concentration meter 51, first flow meter 52, second flow meter 53, sludge pump 32, sludge valve 33 and chemical dosing pump 45 respectively, so as to facilitate centralized management of concentration meter 51, first flow meter 52, second flow meter 53, sludge pump 32, sludge valve 33 and chemical dosing pump 45 through control cabinet 2, thereby realizing integrated control of sludge drying process, simplifying operation process and improving operation convenience.

[0050] Reference Figure 3 An exhaust fan 11 is installed on the housing 1, which is used to dissipate heat from the inside of the housing 1.

[0051] Reference Figure 2 One end of the pipe mixer 6 is connected to the conditioning tank 7, allowing the mixed sludge and chemicals to be transported into the conditioning tank 7. Furthermore, the conditioning tank 7 is connected to a dewatering device 8, facilitating the transport of the conditioned sludge to the dewatering device 8 for dewatering, thereby separating wastewater and sludge cake.

[0052] In this embodiment, the dewatering equipment 8 can be configured as a screw press dewatering machine, a plate and frame filter press, or a belt filter press. Furthermore, the sludge precision conditioning system in this embodiment can be connected to various dewatering equipment 8, thereby achieving modular dewatering treatment.

[0053] In Table 1, Examples 1-8 present basic data obtained through different instruments, including sludge flow rate obtained from a sludge flow meter, sludge moisture content obtained from an online moisture content meter, and then the flow rates of different agents are calculated based on density and other parameters to control the agent dosage. Comparative Examples 1-4 present sludge flow rate obtained from a sludge flow meter, sludge moisture content manually input, and then the flow rates of different agents are calculated based on density and other parameters to control the agent dosage.

[0054]

[0055] Table 1

[0056] Reference Figure 4 As can be seen from the data in Table 1, the technical solution of using the online moisture content analyzer module 5 to accurately control the dosage can save on the amount of pesticides compared with the technical solution that does not use the online moisture content analyzer module 5.

[0057] The implementation principle of the sludge precision conditioning system in this application embodiment is as follows: When sludge conditioning is required, the sludge passage valve 33 is first opened, and the sludge pump 32 is activated to transport the sludge into the pipeline mixer 6. During this process, the concentration meter 51 detects the concentration of the sludge, and the first flow meter 52 detects the amount of sludge, thereby facilitating the calculation of the required dosage.

[0058] Next, the dosing valve 46 is opened, and the dosing pump 45 is activated. According to the required dosage and type of agent, different agents are delivered to the pipeline mixer 6 through the second pipeline 43 and the third pipeline 44 in the corresponding proportions, so that the sludge and the agent are mixed in the pipeline mixer 6 to achieve precise conditioning of the sludge.

[0059] Example 2

[0060] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the pipe mixer 6 includes a connecting part 61, a reducing part 62 and a mixing unit 63.

[0061] Reference Figure 5 At least two connecting portions 61 are provided, and variable diameter portions 62 are installed between adjacent connecting portions 61. In this embodiment, the inner diameter of the variable diameter portion 62 is smaller than the inner diameter of the connecting portion 61, and the connecting portion 61 and the variable diameter portion 62 are in communication, so that a mixing channel 64 is formed between the connecting portion 61 and the variable diameter portion 62, and the mixing unit 63 is installed in the mixing channel 64.

[0062] Reference Figure 3 and Figure 5 The sludge outlet 312, the second pipe 43, and the third pipe 44 are respectively connected to the same connecting part 61, so that the sludge and the agent can be transported into the mixing channel 64 and flow in the mixing channel 64. When the sludge and the agent enter the reducing part 62 from the connecting part 61, the sludge and the agent will be subjected to the squeezing force applied by the inner wall of the reducing part 62, thereby facilitating better mixing of the sludge and the agent.

[0063] Reference Figure 5The mixing unit 63 includes a left-hand spiral blade 631 and a right-hand spiral blade 632. Multiple left-hand spiral blades 631 and right-hand spiral blades 632 are provided, and they are alternately arranged within the mixing channel 64 and adapted to the inner diameter design of the mixing channel 64. In this embodiment, micropores 633 are respectively formed on the left-hand spiral blades 631 and right-hand spiral blades 632.

[0064] When the sludge and the agent flow in the mixing channel 64, the left spiral blade 631 and the right spiral blade 632 can continuously cut and disperse the sludge and the agent. When the sludge and the agent pass through the left spiral blade 631 and the right spiral blade 632, they can pass through the micropores 633 to further disperse the sludge and the agent, thereby improving the mixing efficiency and making it easier to mix the sludge and the agent evenly.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
