Description

Technical Field

[0001] The invention relates to the field of water treatment, and in particular to a hot water supply source circulation filtering and purification treatment system capable of real-time monitoring. Background Art

[0002] As people's living standards continue to improve, the requirements for the quality and stability of hot water supply are also increasing. In various buildings and facilities, the importance of hot water sources is self-evident. However, in the long-term use process, hot water sources may face various pollution and impurity problems, such as particulate matter, sediment, microorganisms in the water, etc. These impurities will not only affect the use experience of hot water, but may also cause damage to related equipment and reduce the service life of the system. In order to ensure the cleanliness and quality of the hot water source, circulating filtration technology came into being. Through circulating filtration, impurities in the water can be effectively removed to ensure the reliability and safety of hot water supply.

[0003] For example, the existing Chinese patent with announcement number CN103112996B discloses a method and device for circulating purification of aquaculture water. This scheme uses a circulating water pump to send the aquaculture water to a protein separator in sequence for protein and organic matter separation and adding some ozone, filtering it through a biomechanical filter, and then sending it to a disinfection processor for secondary ozone disinfection and foam separation and adding remaining ozone, and then removing residual ozone and other harmful gases through an aeration tank. This can effectively purify the aquaculture water, remove impurities such as protein and organic matter, ensure the quality and safety of the aquaculture water, and is conducive to the healthy growth of aquaculture organisms.

[0004] However, the above patent has the following problems: First, the solution realizes the circulation purification of aquaculture water through the steps of disinfection by a sterilizer and precision filtration by a precision filter, but it does not design a comparison of the water quality before and after filtration and purification of aquaculture water, which may lead to the inability to accurately evaluate the actual performance of the system, fail to discover possible problems or deficiencies in a timely manner, and is not conducive to the subsequent optimization and improvement of the system.

[0005] Second, the plan does not involve temperature control of water used. Water temperature is a very important factor for many farmed organisms. Different organisms may have different suitable temperature ranges. In addition to farming, lack of temperature control will also have an impact in other production processes that require specific water temperatures, which may cause product quality to be unstable or non-compliant. Summary of the invention

[0006] In order to overcome the shortcomings of the background technology, the embodiment of the present invention provides a hot water supply source circulation filtering and purification treatment system that can be monitored in real time, which can effectively solve the problems involved in the above-mentioned background technology.

The light intensity change Δλ is obtained by the formula Δλ=|λ1-λ2, and the dissolved oxygen concentration corresponding to the light intensity change is obtained by comparing the light intensity change with the set dissolved oxygen concentration corresponding to each light intensity change, which is denoted as the dissolved oxygen concentration δ of the system inlet water.

[0021] The third step is to use a pH sensor to detect the pH value of the water sample to be tested, and record it as the pH value of the system inlet water.

The qualified degree of the purified system influent water is obtained according to the method of analyzing the qualified degree of the water quality of the system influent, which is recorded as By formula The purification capacity evaluation coefficient χ of the water inlet system is obtained.

[0024] Preferably, the specific analysis method of the water circulation interval duration is as follows: the first step is to read the purification capacity evaluation coefficient of the water inlet system, and at the same time extract the water circulation interval duration of the water inlet system corresponding to the preset purification capacity evaluation coefficient range from the management database.

[0028] Preferably, the specific analysis method of the heating rate compliance degree of the water inlet system is: set the required user temperature for the water inlet system, denoted as Start heating and select a number of time points with equal time intervals during the heating process, record them as temperature time points, detect the water temperature at each temperature time point through the temperature sensor, record two adjacent temperature time points as a group, and obtain the water temperature increment of each group of temperature time points by subtracting the water temperature of the two adjacent temperature time points, record it as x represents the number of the xth temperature time point, x=1,2,...,y, and the time interval is t. Get the heating rate v of the water inlet system, y represents the number of groups of temperature time points, and substitute it into the formula The heating rate compliance degree ρ of the water inlet system is obtained, and v0 represents the reference value of the heating rate.

[0029] Preferably, the specific analysis method of the comprehensive evaluation module is: read the water inlet stability α, filtration capacity evaluation coefficient λ, purification capacity evaluation coefficient χ, water circulation smoothness l, heating rate compliance degree ρ of the water inlet system, and substitute them into the formula Get the comprehensive evaluation index of the water inlet system w1, w2, w3, w4, and w5 respectively represent the weight factors of the set water inlet stability, filtration capacity evaluation coefficient, purification capacity evaluation coefficient, water circulation smoothness, and heating rate compliance. The comprehensive evaluation index of the water inlet system is compared with the preset comprehensive evaluation index threshold. If the comprehensive evaluation index of the water inlet system is greater than or equal to the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of the water inlet system is qualified. If the comprehensive evaluation index of the water inlet system is less than the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of the water inlet system is unqualified, and feedback is given to the system.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] See also Figure 1 As shown, a hot water supply source circulation filtration and purification treatment system capable of real-time monitoring includes a water inlet analysis module, a filtration capacity analysis module, a purification capacity analysis module, a water circulation module, a heating module, a comprehensive evaluation module, and a management database.

[0041] The water inlet analysis module, filtration capacity analysis module, purification capacity analysis module, water circulation module, and heating module are connected to the comprehensive evaluation module, and the water inlet analysis module, filtration capacity analysis module, purification capacity analysis module, water circulation module, heating module, and comprehensive evaluation module are connected to the management database.

[0042] The water inlet analysis module is used to detect the water inlet flow rate and water inlet pressure fluctuation degree of the water inlet system in each time period, and analyze and obtain the water inlet stability α of the water inlet system.

[0043] The specific analysis method of the water inlet analysis module is as follows: the first step is to introduce the hot water source to be treated into the system, and divide the time period according to the set time length, and install a flow meter on the water inlet pipe to detect the water inflow of the water inlet system in each time period, which is recorded as F i , i represents the number of the i-th time period, i=1,2,...,n, and the set duration is recorded as Δt. Get the water flow rate Q of the water inlet system in each time period i, n represents the number of time periods. At the same time, several time points are selected when the water inlet system is inlet. The water inlet pressure at each time point of the water inlet system is detected by the pressure sensor installed on the water inlet pipe, which is recorded as P m , the average water inlet pressure of the water inlet system is obtained by taking the average value of the water inlet pressure at each time point, denoted as P, and substituting it into the formula The water inlet pressure fluctuation degree ΔP of the water inlet system is obtained, and q represents the number of time points; by real-time monitoring of the water inlet flow and pressure, abnormal situations can be discovered in time and corresponding measures can be taken to ensure the stability and safety of system operation.

[0044] The second step is to calculate the water flow rate Q of the water inlet system at each time period. i , Substitute the water inlet pressure fluctuation degree ΔP into the formula The water inlet stability α of the water inlet system is obtained, where φ1 and φ2 represent the weight factors of the set water inlet flow fluctuation degree and water inlet pressure fluctuation degree respectively, e represents a natural constant, and n represents the number of time periods. This helps to promptly discover possible problems or potential risks in the water inlet system so that measures can be taken in advance to improve and correct them, thereby ensuring the continuous and stable operation of the water inlet system and improving the reliability and efficiency of the entire system.

[0045] It should be noted that in a specific embodiment, φ1 can be set to 0.6 and φ2 can be set to 0.4. The instability of the flow rate will directly affect the water supply in the subsequent water use process, and may cause abnormal operation of the water-using equipment, reduced efficiency and other problems. If the flow rate fluctuates too much, it may cause great interference to the normal operation of the entire system, and the pressure fluctuation may affect the smoothness of the water flow, the pressure bearing capacity of the equipment and the working state of some pressure-related control elements. However, in some cases, if the system has good adaptability or adjustment capabilities to the pressure, its impact may be relatively smaller than the degree of flow fluctuation. Therefore, the weight corresponding to the degree of water inlet flow fluctuation is slightly higher.

[0046] The filtering capacity analysis module is used to detect the turbidity and particulate matter content of the system inlet water, and analyze to obtain the filtering capacity evaluation coefficient λ of the inlet water system.

[0047] The specific analysis method of the filtering capacity analysis module is as follows: in the first step, a light beam is emitted to the system inlet water at each time point through a turbidity meter, and the scattered light intensity in the system inlet water at each time point is detected, which is recorded as the scattered light intensity of the system inlet water at each time point, and the turbidity corresponding to each preset scattered light intensity range is read from the management database, and the turbidity of the system inlet water at each time point is matched and recorded as ξ m , through the formula The turbidity of the system inlet water ξ is obtained, and q represents the number of time points; it helps to detect water quality abnormalities in a timely manner and take measures to improve them, thereby ensuring the cleanliness and safety of water.

[0048] In the second step, a number of samples are extracted from the system inlet water as random inspection samples, which are recorded as random inspection water samples. The random inspection water samples are weighed and recorded as M. The random inspection water samples are filtered by using a filter membrane with a set pore size, and the particles remaining on the filter membrane are dried and weighed and recorded as M'. Get the particle content of the system inlet water υ, M 总 Indicates the total amount of incoming water; helps to effectively monitor the quality of incoming water, promptly identify and resolve potential problems, and ensure long-term stable operation of the system.

[0049] The specific analysis method of the filtration capacity evaluation coefficient of the water inlet system is as follows: according to the method of analyzing the turbidity and particulate matter content of the system inlet water, the system inlet water is analyzed again after being filtered through the first filtering device, and the turbidity and particulate matter content of the system inlet water after the first filtration are obtained, which are recorded as ξ' and υ' respectively, and substituted into the formula The filtration capacity evaluation coefficient λ of the water inlet system is obtained, where They respectively represent the weight factors of the set turbidity and particulate matter content; clearly understanding the actual filtration capacity of the first filter device and intuitively reflecting its removal effect on turbidity and particulate matter will help to achieve accurate quality control of the filtration process and ensure that the treated water quality meets the requirements.

[0050] It should be noted that, in a specific embodiment, It can be set to 0.7. It can be set to 0.3. Turbidity reflects the overall situation of suspended particulate matter in the water. It has a direct impact on the transparency and appearance of the water. Higher turbidity not only affects the senses, but may also indicate that there are more large-sized particles in the water, which puts higher demands on the filtration system. If the filtration system cannot effectively reduce the turbidity, it may cause problems in subsequent water use. Therefore, the weight corresponding to turbidity is relatively large.

[0051] It should be noted that in some water treatment or liquid filtration systems, the first filtering device for incoming water may usually be a coarse filter or a pre-filter. The coarse filter can initially intercept larger particles, impurities, etc., and play a role in preliminary filtration and protection of subsequent more refined filtering devices.

[0052] The purification capacity analysis module is used to detect the water quality parameters of the system inlet water, analyze the water quality of the system inlet water, and then analyze the purification capacity evaluation coefficient χ of the inlet water system. The water quality parameters include residual chlorine, dissolved oxygen concentration, and pH value.

[0053] The specific analysis method of the water quality parameters of the system inlet water is as follows: the first step is to extract a number of samples to be tested from the inlet water after passing through the first filtering device, which are recorded as the water samples to be tested; select a plurality of time points of residual chlorine according to the set time interval, which are recorded as each time point to be tested; place the residual chlorine electrode and the reference electrode in the water samples to be tested; monitor the current value of the water samples to be tested at each time point to be tested; obtain the current change by subtracting the current values ​​of the water samples to be tested at two adjacent time points to be tested; compare the current change with a preset current change corresponding to the residual chlorine standard curve to obtain the residual chlorine amount corresponding to the current change, which is recorded as the residual chlorine amount σ of the system inlet water; by comparing with the standard curve, ensure that the residual chlorine amount is within a reasonable range to avoid excessive or too low residual chlorine from affecting human health and equipment.

[0054] It should be noted that the specific analysis method of the current change is: read the current value of the water sample to be tested at each time point to be tested, recorded as I f , f represents the number of the f-th time point to be tested, f=1,2,...,k, substitute it into the formula The current variation ΔI is obtained, and k represents the number of time points to be measured.

[0055] The second step is to project an infrared light source onto the water sample to be tested, and detect the light intensity at the front and rear ends of the light source passing through the water sample to be tested, respectively, which are recorded as λ1 and λ2. The light intensity change Δλ is obtained by the formula Δλ=|λ1-λ2. The dissolved oxygen concentration corresponding to the light intensity change is obtained by comparing the light intensity change with the set dissolved oxygen concentration corresponding to each light intensity change, which is recorded as the dissolved oxygen concentration δ of the system inlet water. The dissolved oxygen status of the system inlet water can be understood in real time to detect abnormalities in time. The appropriate dissolved oxygen concentration is crucial to the aquatic ecosystem and helps to maintain the normal survival and reproduction of aquatic organisms.

[0056] The third step is to use a pH sensor to detect the pH value of the water sample to be tested, and record it as the pH value of the system's inlet water. This can promptly detect abnormal fluctuations in the pH value, indicate possible water quality problems, and ensure that the pH value of the inlet water is within the appropriate range to avoid adverse effects on subsequent use or treatment.

[0057] The specific analysis method for the water quality of the system inlet water is as follows: the first step is to read the residual chlorine content σ, dissolved oxygen concentration δ, and pH value PH of the system inlet water respectively, and substitute them into the formula Get the water quality of the system inlet water σ0, δ0, and PH0 represent the reference values ​​of the set residual chlorine, dissolved oxygen concentration, and pH value, respectively; η1, η2, and η3 represent the weight factors of the set residual chlorine, dissolved oxygen concentration, and pH value, respectively; timely discover possible water quality problems so that relevant parameters in the water treatment process can be adjusted in a targeted manner according to the degree of water quality, such as the amount of disinfectant added, to optimize the treatment effect.

[0058] It should be noted that, in a specific embodiment, η1 can be set to 0.4, η2 can be set to 0.3, and η2 can be set to 0.3. The residual chlorine content is directly related to the disinfection effect and sanitary safety of water. If the residual chlorine content does not meet the standard, there may be a risk of contamination by microorganisms such as bacteria and viruses, which has a greater impact on health. The dissolved oxygen concentration is also relatively important. It will affect the survival of aquatic organisms and the balance of the ecosystem. In some cases where there are requirements for water ecology, the weight will be relatively large. The pH value is also not to be ignored. It affects the chemical stability and corrosiveness of water. Inappropriate pH values ​​may cause damage to pipes, equipment, etc., and have a greater impact in some occasions that are sensitive to the chemical properties of water. Therefore, the weight corresponding to the residual chlorine content is slightly higher, and the weights corresponding to the dissolved oxygen concentration and pH value are equal.

[0059] In the second step, the purified system influent is analyzed according to the method of analyzing the residual chlorine content, dissolved oxygen concentration and pH value of the system influent, and the residual chlorine content, dissolved oxygen concentration and pH value of the purified system influent are obtained. The qualified degree of the purified system influent water is obtained according to the method of analyzing the qualified degree of the water quality of the system influent, which is recorded as By formula The purification capacity evaluation coefficient χ of the water inlet system is obtained; it helps to reasonably allocate resources to improve purification capacity or improve related links. Continuous monitoring and evaluation can better ensure that the purified water quality meets the requirements and improve water safety.

[0060] The water circulation module is used to control the water circulation interval according to the purification capacity evaluation coefficient of the water inlet system, detect the circulating water flow rate and the degree of fluctuation of the circulating water pressure, and analyze the smoothness of the water circulation of the water inlet system.

[0061] See also Figure 2 As shown, the specific analysis method of the water circulation interval is as follows: the first step is to read the purification capacity evaluation coefficient of the water inlet system, and at the same time extract the water circulation interval of the water inlet system corresponding to the preset purification capacity evaluation coefficient range from the management database; accurately determine the appropriate water circulation interval according to the purification situation, realize the rational use and efficient management of water resources, avoid unnecessary water circulation or non-circulation for too long, and make the system operation more optimized.

[0062] The second step is to match the purification capacity evaluation coefficient of the water inlet system with the water circulation interval duration of the water inlet system corresponding to each purification capacity evaluation coefficient range, and obtain the water circulation interval duration corresponding to the purification capacity evaluation coefficient of the water inlet system; this helps to optimize resource utilization, avoid excessive or insufficient water circulation, achieve the purpose of energy saving and efficient operation, and at the same time ensure that the purification effect of the water inlet system is always in an ideal state, thereby improving the stability of water quality.

[0063] It should be noted that, in a specific embodiment, the purification capacity evaluation coefficient is divided into three levels: low, medium and high. When the purification capacity evaluation coefficient is at a low level, the water circulation interval of the water inlet system can be set to 12 hours, when it is at a medium level, the water circulation interval can be set to 8 hours, and when it is at a high level, the water circulation interval can be set to 4 hours. If the current purification capacity evaluation coefficient is at a low level, the water inlet system circulates water every 12 hours. As the water quality changes and the purification effect improves or decreases, the purification capacity evaluation coefficient changes accordingly, thereby adjusting the water circulation interval to ensure that the water quality always remains in a good state.

[0064] The third step is to set the water circulation interval of the water inlet system according to the water circulation interval corresponding to the purification capacity evaluation coefficient of the water inlet system; this can adapt to the actual purification conditions of the water inlet system to the greatest extent, ensure the continuous stability of the purification effect, effectively improve the efficiency of water resource utilization, and avoid unnecessary water circulation and waste of resources.

[0065] The specific analysis method of the water circulation smoothness of the water inlet system is as follows: the water circulation time of the water inlet system is divided into several time periods according to the set fixed time period, which are recorded as each water circulation time period, and each water circulation time period of the water inlet system is analyzed according to the method of analyzing the water inlet flow rate and the degree of fluctuation of the water inlet pressure in each time period of the water inlet system, and the circulating water flow rate and the degree of fluctuation of the circulating water pressure in each water circulation time period of the water inlet system are obtained, which are recorded as Q j , ΔP 循环 , j represents the number of the jth water cycle period, j = 1, 2, ..., g, and substitute it into the formula The water circulation smoothness l of the water inlet system is obtained, Q0 represents the set reference value of the circulating water flow rate, g represents the number of water circulation periods, μ1 and μ2 represent the weight factors of the set circulating water flow rate and circulating water pressure fluctuation degree, and e represents a natural constant; it is helpful to timely discover the periods of abnormal water inlet flow and pressure fluctuation, facilitate targeted maintenance and adjustment, help realize the refined management of the water inlet system, and improve the reliability and stability of the system.

[0066] It should be noted that, in a specific embodiment, μ1 can be set to 0.5, and μ2 can be set to 0.5. Sufficient and stable circulating water flow rate is the key basis for ensuring smooth water circulation. Insufficient flow rate may directly lead to poor system operation or even failure, so it plays a vital role in the smoothness of water circulation. The degree of circulating water pressure fluctuation cannot be ignored. Large pressure fluctuations may have adverse effects on equipment and pipelines in the system, such as causing vibration and damage, thereby affecting the stability and smoothness of the water circulation. Therefore, the weights corresponding to the circulating water flow rate and the degree of circulating water pressure fluctuation are equal.

[0067] The heating module is used to detect the heating rate of the water inlet system and analyze the compliance degree ρ of the heating rate of the water inlet system.

[0068] The specific analysis method of the heating rate compliance degree of the water inlet system is: set the required user temperature for the water inlet system, denoted as Start heating and select a number of time points with equal time intervals during the heating process, record them as temperature time points, detect the water temperature at each temperature time point through the temperature sensor, record two adjacent temperature time points as a group, and obtain the water temperature increment of each group of temperature time points by subtracting the water temperature of the two adjacent temperature time points, record it as x represents the number of the xth temperature time point, x=1,2,...,y, and the time interval is t. Get the heating rate v of the water inlet system, y represents the number of groups of temperature time points, and substitute it into the formula The heating rate compliance degree ρ of the water inlet system is obtained, and v0 represents the reference value of the heating rate.

The comprehensive evaluation index of the water inlet system is compared with the preset comprehensive evaluation index threshold. If the comprehensive evaluation index of the water inlet system is greater than or equal to the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of the water inlet system is qualified. If the comprehensive evaluation index of the water inlet system is less than the preset comprehensive evaluation index threshold, it means that the comprehensive evaluation index of the water inlet system is unqualified, and feedback is given to the system.

[0072] The management database is used to store the turbidity corresponding to each scattered light intensity range, the standard current value of water use, and the water circulation interval time of the water inlet system corresponding to each purification capacity evaluation coefficient range.
