Description

Technical Field

[0001] The utility model relates to a cooling water dosing system, in particular to a circulating cooling water dosing system for constant temperature compressed air in the vortex spinning process, belonging to the technical field of water resource recycling in the vortex spinning process of textile. Background Art

[0002] Vortex spinning is a new spinning method, which is improved on the basis of air-jet spinning (MJS) by Murata Company in Japan and is especially suitable for spinning pure cotton. It uses the action of air vortex to condense and twist the fibers in a single fiber state into yarn, thus avoiding the need for rotating parts, simplifying the structure and increasing the spinning speed, which is generally 6-7 times higher than ring spinning. The principle of vortex spinning is to loosen the fiber strip into single fiber state by a carding roller, and then, by the action of air flow (compressed air), the fibers enter the vortex tube through the tangential channel to form a fiber flow; then, a number of air inlet holes are opened tangentially along the circumference at an appropriate position in the vortex tube, and the outside air enters the vortex tube at high speed along the tangential air inlet holes to form a vortex. The high-speed rotating vortex moves along the axis of the vortex tube and rotates in the same direction as the fiber flow fed into the tangential channel to achieve axial balance. At the balance position, the vortex pushes the free end of the yarn tail to rotate at high speed in a circular shape, and the continuously fed fibers meet the moving yarn tail and condense onto the yarn tail to form yarn. Since the vortex is used to replace the mechanical twisting and condensing action, the structure is simple and the spinning speed is relatively high.

[0003] Among them, vortex spinning uses compressed air as the power source for yarn forming and uses compressed air to guide the fibers into the vortex tube. Therefore, strict requirements are imposed on the temperature and humidity of the compressed air.

[0004] In the vortex spinning process, when the temperature of the compressed air is too high, it will cause a decrease in the moisture regain rate of the yarn, and then make the yarn dry and have more hairiness; when the temperature of the spinning compressed air is too low, it will cause the yarn to be brittle and break easily and the hairiness to increase, thus affecting the yarn quality. Therefore, it is necessary to perform real-time constant temperature control on the compressed air (for example: CN220183464U, a constant temperature control system for compressed air used in vortex spinning). When the ambient temperature of the working condition changes, the cooling system of the compressed air is adjusted in time to control the temperature of the spinning compressed air, and to ensure that there is no difference in the yarn quality in the same batch of yarns (even the same roll of yarns) in the textile mill, reduce the fluctuations in spinning efficiency and output, and facilitate the downstream process control, etc.

[0005] However, due to the multiple cycles of the circulating cooling water in the cooling system in the conveying pipeline, scale is likely to form in the conveying pipeline. Also, the cooling water repeatedly contacts the atmosphere in the cooling tower, washing the dust in the atmosphere and bringing it into the circulating cooling water to form suspended solids. The more suspended solids there are, the greater the turbidity of the cooling water will be. When the turbidity is too high, a considerable amount of slime and suspended solids will deposit in the cooling water. The long-term deposition of slime will cause equipment corrosion, seriously affecting the normal operation of the cooling system, and further affecting the preparation and control of constant-temperature compressed air. Eventually, it will affect the quality and output of vortex yarn, etc.

[0006] Although the prior art CN104250042A discloses an "integrated device and method for automatic treatment of circulating cooling water and reuse of sewage", it sets the chemical dosing port on the cooling tower, that is, the chemical agent is directly introduced into the cycle through the chemical dosing device, which may cause problems such as damage to equipment components such as the circulating pipeline, water pump, and heat exchanger by the chemical agent (with acidity, oxidability, etc.); also, the makeup water inlet is set on the cooling tower. Once there is an imbalance between the makeup water pipe and the circulating pipeline, it is easy to have an empty pipe, that is, cavitation occurs, seriously affecting the service life of pumps, etc. CN111003838A discloses a "water quality automatic monitoring and chemical dosing system for diesel engine circulating cooling water", which is mainly applicable to the monitoring and treatment of diesel engine circulating cooling water.

[0007] Therefore, a chemical dosing system applicable to the vortex spinning process, for constant-temperature compressed air, and for the circulating cooling water in the cooling system is needed. Summary of the Invention

[0008] In order to solve the problems that the circulating cooling water for constant-temperature compressed air in the vortex spinning process has poor water quality and unstable water quality, which affect the normal operation of the cooling system, and further affect the preparation and control of constant-temperature compressed air, and ultimately lead to poor quality and low output of vortex yarn, etc., a chemical dosing system for the circulating cooling water for constant-temperature compressed air in the vortex spinning process is proposed.

[0009] Among them, through the reasonable arrangement of each chemical preparation tank, each feeding metering pump, water quality detector, controller, etc., the automatic regulation of the water quality of industrial circulating cooling water is realized to meet the water quality requirements of the cooling water system for constant-temperature compressed air, and further ensure the quality and output of vortex yarn.

[0010] In order to achieve the above technical objectives, the following technical solutions are proposed:

[0011] The circulating cooling water dosing system for constant-temperature compressed air in the vortex spinning process is arranged in the cooling system for constant-temperature compressed air. The cooling system includes a reservoir and a cooling tower. The reservoir is connected with a makeup water pipe. The reservoir is connected to the cooling medium inlet of the air compressor in the constant-temperature compressed air preparation system through the cooling water inlet pipe I. The cooling medium outlet of the air compressor is connected to the cooling tower through the cooling water outlet pipe I. The cooling tower is connected to the reservoir through a return water pipe. A continuous path for cooling water circulation is formed among the reservoir, the cooling water inlet pipe I, the air compressor, the cooling water outlet pipe I, the cooling tower and the return water pipe;

[0012] The circulating cooling water dosing system includes a water quality detector, a scale and corrosion inhibitor preparation tank, an oxidizing biocide preparation tank, a non-oxidizing biocide preparation tank and a controller arranged on the reservoir. The scale and corrosion inhibitor preparation tank is connected with a scale and corrosion inhibitor storage tank. The scale and corrosion inhibitor preparation tank is connected to the reservoir through a scale and corrosion inhibitor inlet pipe. A scale and corrosion inhibitor feed metering pump and a scale and corrosion inhibitor feed regulating valve are arranged on the scale and corrosion inhibitor inlet pipe;

[0013] The oxidizing biocide preparation tank is connected with an oxidizing biocide storage tank. The oxidizing biocide preparation tank is connected to the reservoir through an oxidizing biocide inlet pipe. An oxidizing biocide feed metering pump and an oxidizing biocide feed regulating valve are arranged on the oxidizing biocide inlet pipe;

[0014] The non-oxidizing biocide preparation tank is connected with a non-oxidizing biocide storage tank. The non-oxidizing biocide preparation tank is connected to the reservoir through a non-oxidizing biocide inlet pipe. A non-oxidizing biocide feed metering pump and a non-oxidizing biocide feed regulating valve are arranged on the non-oxidizing biocide inlet pipe;

[0015] The scale and corrosion inhibitor feed metering pump, the scale and corrosion inhibitor feed regulating valve, the oxidizing biocide feed metering pump, the oxidizing biocide feed regulating valve, the non-oxidizing biocide feed metering pump, the non-oxidizing biocide feed regulating valve and the controller are all electrically connected. The controller and the water quality detector are electrically connected.

[0016] Further, the water quality detector includes a fluorescence sensor (e.g., ST-500 online fluorescence probe), a redox potentiometer (WS-SX712), a conductivity meter (ST-720), a turbidimeter (ST-730), a corrosion rate sensor (CR-300), a hardness detection sensor (TH170), an alkalinity detection sensor (ST0251-1A), and a chloride ion detection sensor (CT-7600). Among them, the concentration of fluorescent agents in water can be detected every 4 seconds by measuring fluorescence technology, and the controller maintains the concentration of target scale and corrosion inhibitors in the system. If the agent concentration value is higher than the set point, the controller will stop dosing; if the agent concentration value is lower than the set point, the controller will turn on the corresponding dosing pump. A feedback closed-loop control is achieved, regardless of the change in heat load and the change in concentration ratio, so that the system agent concentration is always within a small range near the control target, thereby ensuring the stable operation of the cooling system.

[0017] Further, there are multiple water quality detectors, which are evenly distributed on the reservoir. Multi-point online monitoring and centralized control are realized.

[0018] Further, a tap water feed metering pump and a tap water feed regulating valve are provided on the make-up water pipe, and the tap water feed metering pump and the tap water feed regulating valve are electrically connected to the controller.

[0019] Further, frequency converters are connected to the scale and corrosion inhibitor feed metering pump, the oxidizing biocide feed metering pump, the non-oxidizing biocide feed metering pump, and the tap water feed metering pump.

[0020] Further, the reservoir is also connected to the cooling medium inlet of the cold dryer in the constant temperature compressed air preparation system through the cooling water inlet pipe II, and the cooling medium outlet of the cold dryer is connected to the cooling tower through the cooling water outlet pipe II. A continuous path for cooling water circulation is formed among the reservoir, the cooling water inlet pipe II, the cold dryer, the cooling water outlet pipe II, the cooling tower, and the return pipe;

[0021] The cold dryer is arranged at the rear side of the air compressor station. Temperature detectors are provided on both the cold dryer and the air compressor, and the temperature detectors are electrically connected to the controller. This setting ensures that the cooling system coordinated with this dosing system is not only applicable to cooling and dehumidifying the compressed air in the air compressor in the constant temperature compressed air preparation system, but also applicable to cooling and dehumidifying the compressed air in the cold dryer in the constant temperature compressed air preparation system (wherein, it is indirect cooling and dehumidifying. The cooling water directly acts on the cooler for heat exchange and cooling, while the refrigerant in the cooler acts on the compressed air for cooling and dehumidifying).

[0022] Further, the cooling water inlet pipe II is connected to the cooling water inlet pipe I through the branch pipe I, and the cooling water outlet pipe II is connected to the cooling water outlet pipe I through the branch pipe II. The layout of this pipeline improves the flexibility of the inlet and outlet of the cooling water, making it convenient for control. The specific use can be set according to the working conditions and installation environment.

[0023] Further, a sewage outlet is provided on the reservoir.

[0024] In this technical solution, according to actual needs, valves (such as check valves, safety valves, regulating valves, etc.), transfer pumps, pressure gauges, etc. are provided on each pipeline.

[0025] In this technical solution, positional relationships such as "middle", "upper", "between", "uniformly distributed", and "rear side of the working station" are defined according to the actual use state, which are common terms in this technical field and also common terms for those skilled in the art during actual use.

[0026] Adopting this technical solution brings the following beneficial technical effects:

[0027] First, in this utility model, through the reasonable arrangement of each chemical preparation tank, each feeding metering pump, water quality detector, controller, etc., the automatic regulation of the quality of industrial circulating cooling water is realized to meet the requirements of the cooling water system for constant temperature compressed air for water quality, thereby ensuring the quality and output of vortex yarn.

[0028] Second, in this utility model, the water quality detector is arranged on the reservoir, that is, the water quality in the reservoir is monitored; each chemical inlet pipe is connected to the reservoir, that is, the chemicals are directly added into the reservoir to regulate the water quality in the reservoir. On the one hand, it ensures that the chemicals are evenly distributed in the cooling water of the reservoir, improving the high efficiency and high quality of water quality regulation, and then entering the circulating pipeline to improve the stability of the cooling system; on the other hand, since the chemicals are directly added to the cooling water in the storage tank, the concentration of the chemicals can be reduced on the premise of ensuring water quality regulation, avoiding damage to equipment such as pipelines, water pumps, and heat exchangers caused by high-concentration chemicals remaining in the circulating water. Among them, the reservoir is connected with a make-up water pipe. The setting of the reservoir can better avoid the "cavitation" phenomenon, improve the uniformity of chemical distribution, and at the same time, cool the water discharged from the cooling tower again to ensure the function of the circulating cooling water.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] This embodiment provides a circulating cooling water dosing system for constant-temperature compressed air in the vortex spinning process, as Figure 1 shown, which is arranged in the cooling system for constant-temperature compressed air.

[0034] Cooling system: It includes a water storage tank 1 and a cooling tower 2. The water storage tank 1 is connected with a make-up water pipe 3. A sewage outlet 28 is arranged on the water storage tank 1. The water storage tank 1 is connected with the cooling medium inlet of the air compressor 5 in the constant-temperature compressed air preparation system through the cooling water inlet pipe I 4. The cooling medium outlet of the air compressor 5 is connected with the cooling tower 2 through the cooling water outlet pipe I 6. The cooling tower 2 is connected with the water storage tank 1 through the return pipe 7. A continuous path for cooling water circulation is formed among the water storage tank 1, the cooling water inlet pipe I 4, the air compressor 5, the cooling water outlet pipe I 6, the cooling tower 2 and the return pipe 7;

[0035] Circulating cooling water dosing system: It includes a water quality detector 8, a scale and corrosion inhibitor preparation tank 9, an oxidizing biocide preparation tank 10, a non-oxidizing biocide preparation tank 11 and a controller 12 installed on the reservoir 1. The scale and corrosion inhibitor preparation tank 9 is connected to a scale and corrosion inhibitor storage tank 13 (e.g., filled with scale and corrosion inhibitor AD-303). The scale and corrosion inhibitor preparation tank 9 is connected to the reservoir 1 through a scale and corrosion inhibitor inlet pipe 14. A scale and corrosion inhibitor feed metering pump 15 and a scale and corrosion inhibitor feed regulating valve 29 are provided on the scale and corrosion inhibitor inlet pipe 14;

[0036] The oxidizing biocide preparation tank 10 is connected to an oxidizing biocide storage tank 16 (e.g., filled with oxidizing biocide AD-401). The oxidizing biocide preparation tank 10 is connected to the reservoir 1 through an oxidizing biocide inlet pipe 17. An oxidizing biocide feed metering pump 18 and an oxidizing biocide feed regulating valve 30 are provided on the oxidizing biocide inlet pipe 17;

[0037] The non-oxidizing biocide preparation tank 11 is connected to a non-oxidizing biocide storage tank 19 (e.g., filled with non-oxidizing biocide AD-402). The non-oxidizing biocide preparation tank 11 is connected to the reservoir 1 through a non-oxidizing biocide inlet pipe 20. A non-oxidizing biocide feed metering pump 21 and a non-oxidizing biocide feed regulating valve 31 are provided on the non-oxidizing biocide inlet pipe 20;

[0039] For the dosing amount of each chemical agent, it can be limited according to actual needs. For example:

[0040] For the first shock dosing, add 400 mg / L of scale and corrosion inhibitor AD-303 to the reservoir 1 (calculated based on the retained water volume). Subsequently, the chemical agent dosing is carried out in a normal intermittent manner. Among them, the first dosing amount = dosing concentration × retained water volume, that is, the first dosing amount = 400 mg / L × 250 m³ = 100 kg; when the equipment is operating normally, the scale and corrosion inhibitor is dosed once a day, and the dosing amount each time is 100 mg / L; the daily dosing amount = dosing concentration × circulating water volume, and the daily dosing amount = 100 mg / L × 1000 m³ / h = 10 kg.

[0048] Table 3

[0049]

[0050] Example 2

[0051] Based on Example 1, in this example, the water quality detector 8 is further defined to further illustrate the technical solution.

[0052] The water quality detector 8 includes a fluorescence sensor (such as: ST-500 on-line fluorescence probe), an oxidation-reduction potentiometer (WS-SX712), a conductivity meter (ST-720), a turbidimeter (ST-730), a corrosion rate sensor (CR-300), a hardness detection sensor (TH170), an alkalinity detection sensor (ST0251-1A), and a chloride ion detection sensor (CT-7600). Among them, the concentration of the fluorescent agent in the water can be detected every 4 seconds by measuring the fluorescence technology, and the concentration of the target scale and corrosion inhibitor in the system is maintained by the controller 12. If the agent concentration value is higher than the set point, the controller 12 will stop adding the drug; if the agent concentration value is lower than the set point, the controller 12 will turn on the corresponding dosing pump. To achieve feedback closed-loop control, regardless of the change in heat load and regardless of the change in concentration multiple, the system agent concentration is always in a small range near the control target, thereby ensuring the stable operation of the cooling system.

[0053] Among them, the number of water quality detectors 8 involved is multiple, and they are evenly distributed on the reservoir 1. To achieve multi-point on-line monitoring and centralized control.

[0054] Regarding the basis for selecting each water quality detector 8, it depends on the actual situation. For example:

[0055] During the operation of the circulating water system, when the alkalinity exceeds the standard, if there is enough makeup water, the blowdown volume should be increased to ensure the normal operation of the system; if the makeup water is not sufficient during operation, sulfuric acid should be added for adjustment, and the specific acid addition amount is calculated according to the actual operation;

[0056] During the operation of the system, if the hardness or the content of calcium and magnesium ions exceeds the standard by a small margin, within 10% - 20%, the dosage of the chemical agent should be increased to ensure that scale formation on the heat exchange equipment does not occur during operation; if the hardness or the content of calcium and magnesium ions exceeds this range and seriously exceeds the standard during the detection process, the blowdown volume should be increased to achieve the purpose of scale prevention.

[0057] The circulating water repeatedly contacts the atmosphere in the cooling tower 2, washing down the dust in the atmosphere and bringing it into the circulating water to form suspended solids. The more suspended solids there are, the greater the turbidity of the water will be. During the operation of the system, attention should be paid to controlling the turbidity index. Generally, the turbidity should be less than 20.0 NTU. If it exceeds 20.0 NTU, the makeup water volume of the system should be increased. Because when the turbidity is too high, a considerable amount of slime and suspended solids will be deposited in the water. If the slime is deposited for a long time, it will cause corrosion of the equipment and affect the normal operation.

[0058] During the operation process, the pH value of the circulating water should be strictly controlled. If the pH value is too low, it will also cause serious corrosion to the equipment. During treatment, the blowdown treatment should be strengthened; if the pH value is too high, acid addition treatment should be carried out on the system.

[0059] During the operation of the system, it is necessary to strengthen the supervision and detection of chloride ions. If the chloride ion content in the circulating cooling water is high (chloride ion control value ≤ 500), it will damage the protective film on the surface of the heat exchange tube, easily cause layered dezincification, and result in equipment corrosion. Therefore, it is necessary to further regulate it to ensure the safe and economic operation of the equipment.

[0060] Example 3

[0061] On the basis of Examples 1 - 2, in order to better achieve the regulation of chemical agent addition in this example, it is further defined that:

[0062] A tap water feed metering pump 22 is provided on the makeup water pipe 3, and there is an electrical connection between the tap water feed metering pump 22, the tap water feed regulating valve 32 and the controller 12.

[0063] In addition, a frequency converter is connected to each of the scale and corrosion inhibitor feed metering pump 15, the oxidizing biocide feed metering pump 18, the non - oxidizing biocide feed metering pump 21 and the tap water feed metering pump 22.

[0064] Example 4

[0065] On the basis of Examples 1 - 3, in order to ensure the practicability and adaptability of this circulating cooling water chemical agent addition system, this example further shows:

[0066] The water storage tank 1 is also connected to the cooling medium inlet of the cold dryer 23 in the constant-temperature compressed air preparation system through the cooling water inlet pipe II 24. The cooling medium outlet of the cold dryer 23 is connected to the cooling tower 2 through the cooling water outlet pipe II 25. A continuous path for cooling water circulation is formed among the water storage tank 1, the cooling water inlet pipe II 24, the cold dryer 23, the cooling water outlet pipe II 25, the cooling tower 2 and the return water pipe 7;

[0067] The cold dryer 23 is arranged at the rear side of the working station of the air compressor 5. Temperature detectors are provided on both the cold dryer 23 and the air compressor 5, and the temperature detectors are electrically connected to the controller 12. This setting ensures that the cooling system cooperating with this dosing system is not only applicable to cooling and water removal of the compressed air in the air compressor 5 in the constant-temperature compressed air preparation system, but also applicable to cooling and water removal of the compressed air in the cold dryer 23 in the constant-temperature compressed air preparation system (wherein, it is indirect cooling and water removal. The cooling water directly acts on the cooler for heat exchange and cooling, while the freon in the cooler acts on the compressed air for cooling and water removal).

[0068] In addition, the cooling water inlet pipe II 24 is connected to the cooling water inlet pipe I 4 through the branch pipe I 26, and the cooling water outlet pipe II 25 is connected to the cooling water outlet pipe I 6 through the branch pipe II 27. The layout of this pipeline improves the flexibility of the inlet and outlet of the cooling water and is convenient for control. The specific use can be set according to the working conditions and installation environment.
