[0061] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0062] As Figure 1 shown, an embodiment of the present invention provides a medical waste steam cooling spray control method, which is applied to a medical waste steam cooling spray system. The medical waste steam cooling spray system includes: a vapor-liquid pipeline; a first medical waste steam cooling spray tower connected to the vapor-liquid pipeline through a first vapor-liquid inlet valve; and a second medical waste steam cooling spray tower connected to the vapor-liquid pipeline through a second vapor-liquid inlet valve. Wherein, both the first medical waste steam cooling spray tower and the second medical waste steam cooling spray tower include: a tower body 1; a spray device extending into the top of the tower body 1; a sewage discharge device opened at the bottom of the tower body 1; a steam outlet 21, a steam inlet 22, a first liquid level gauge port 23, a drain port 24, and a second liquid level gauge port 25 opened on the side wall of the tower body 1 from high to low in sequence; a control system respectively connected to the first vapor-liquid inlet valve, the second vapor-liquid inlet valve, the first medical waste steam cooling spray tower, and the second medical waste steam cooling spray tower. The method includes:

[0063] Step 11, obtaining a target waste steam treatment signal;

[0064] Step 12, according to the target waste steam treatment signal, sending a first vapor-liquid inlet valve opening signal or sending a second vapor-liquid inlet valve opening signal;

[0065] Step 13, receiving a target liquefaction degree signal;

[0066] Step 14, according to the target liquefaction degree signal, determining a first target spray parameter of the first medical waste steam cooling spray tower or a second target spray parameter of the second medical waste steam cooling spray tower;

[0067] Step 15, according to the first vapor-liquid inlet valve opening signal or the second vapor-liquid inlet valve opening signal, and the first target spray parameter or the second target spray parameter, controlling the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower to perform a cooling spray treatment on the medical waste steam.

[0068] In this embodiment, when the medical waste steam cooling spray control system receives a target waste steam treatment signal, it makes a judgment through a preset judgment logic to determine the medical waste steam cooling spray tower for this target waste steam treatment. As Figure 2As shown, the medical waste steam cooling spray control system controls two medical waste steam cooling spray towers. The first medical waste steam cooling spray tower and the second medical waste steam cooling spray tower are used alternately in a cycle. The two towers are interconnected through connecting pipes to achieve the cyclic flow of fluids. The double-tower structure in this embodiment can greatly improve the processing capacity of the cooling tower and meet the needs of large-scale cooling of medical waste steam. After determining that it is necessary to start the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower, the control system receives the target liquefaction degree signal input by the staff, determines the target spray parameters of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower according to the required liquefaction degree, and performs cooling spray treatment on the medical waste steam according to the determined target spray parameters. During the process of the medical waste steam cooling spray tower performing cooling spray on the medical waste steam, the medical waste steam cooling spray control system monitors the operating states of the first medical waste steam cooling spray tower and the second medical waste steam cooling spray tower in real time, including parameters such as temperature, pressure, and flow rate, and performs automatic adjustment according to a preset program. The control system can also control each component of the cooling tower, such as the start and stop of the spray device, the opening and closing of the valve, etc. Through the control system, the efficient and stable operation of the cooling tower can be achieved, and the cooling efficiency can be improved.

[0069] In an optional embodiment of the present invention, step 12 may include:

[0070] Step 121, according to the target waste steam treatment signal, receive the first in-tower temperature sensor signal of the first medical waste steam cooling spray tower and the second in-tower temperature sensor signal of the second medical waste steam cooling spray tower;

[0071] Step 122, according to the first in-tower temperature sensor signal and the second in-tower temperature sensor signal, determine the current temperature difference between the first medical waste steam cooling spray tower and the second medical waste steam cooling spray tower;

[0072] Step 123, according to the current temperature difference, send a first steam inlet and liquid valve opening signal or send a second steam inlet and liquid valve opening signal.

[0073] In this embodiment, in order to ensure the balance of the maintenance cycles of the two medical waste steam cooling spray towers, a judgment method of selecting a tower according to the in-tower temperature is set. The medical waste steam cooling spray system receives the in-tower temperature sensor signals of the two towers, judges the current temperature difference between the in-towers of the two towers, and judges whether the current in-tower states of the two towers differ too much according to the temperature difference. According to the in-tower states of the two towers, select the medical waste steam cooling spray tower currently performing waste steam treatment.

[0074] Specifically, step 123 may include:

[0075] Step 1231: When the current temperature difference is less than or equal to the first preset threshold, determine the counter time of the first medical waste steam cooling spray tower and the counter time of the second medical waste steam cooling spray tower;

[0076] Here, when the current temperature difference is small, it indicates that the internal states of the two towers are not very different. At this time, the system obtains the counter time of each of the two towers.

[0077] Step 1232: According to the counter time, send a first steam and liquid inlet valve opening signal or send a second steam and liquid inlet valve opening signal; the counter time is the time from the current time to the last use time of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower;

[0078] Here, select the cooling spray tower with the larger counter for medical waste treatment. That is, when the counter time of the first medical waste steam cooling spray tower is greater than the counter time of the second medical waste steam cooling spray tower, it means that the first medical waste steam cooling spray tower has a longer time since the last medical waste treatment. To ensure that the two towers have a balanced maintenance buffer time, at this time, select the first medical waste steam cooling spray tower with the larger counter for medical waste steam treatment.

[0079] Step 1233: When the current temperature difference is greater than the first preset threshold, according to the magnitude relationship between the first in-tower temperature sensor signal and the second in-tower temperature sensor signal, send a first steam and liquid inlet valve opening signal or send a second steam and liquid inlet valve opening signal.

[0080] Here, when the current temperature difference is greater than the first preset threshold, it indicates that the states of the two towers are very different. To ensure the efficiency and quality of medical waste steam treatment, select a spray tower that is more conducive to the liquefaction treatment of medical waste steam for waste steam treatment, that is, select the medical waste steam cooling spray tower with a lower temperature.

[0081] In an optional embodiment of the present invention, step 14 may include:

[0082] Step 141: According to the target liquefaction degree signal, determine the target temperature of the outlet of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower;

[0083] Step 142: Obtain the flow rate of the current medical waste steam in the target waste steam treatment signal;

[0084] Step 143: According to the target temperature and the flow rate of the current medical waste steam, determine the target spray flow rate parameter of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower;

[0085] Step 144: Obtain the pump parameters of the first water pump or the second water pump;

[0086] Step 145: Obtain the target spray pressure parameter of the preset first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower according to the water pump parameters.

[0087] Step 146: Obtain the first target spray parameter of the first medical waste steam cooling spray tower or the second target spray parameter of the second medical waste steam cooling spray tower according to the target spray flow parameter and the target spray pressure parameter.

[0088] In this embodiment, since the temperature of the medical waste steam in the steam inlet of the medical waste steam cooling spray tower is basically constant, the degree of liquefaction treatment of the medical waste steam can be measured by the temperature at the steam outlet. Manually select the target liquefaction degree, and the system infers the temperature at the steam outlet corresponding to the target liquefaction degree according to the selected target liquefaction degree and the general temperature of the steam inlet. According to the target outlet temperature to be achieved and the steam flow monitored by the steam flowmeter at the steam inlet, through the formula Q 喷淋 = k·Q 气体 ·(T 进汽口 - T 目标温度 ), determine the flow rate of the spray head in the cooling spray tower, where Q 喷淋 is the flow rate of the spray head, that is, the target spray flow parameter, k is an empirical coefficient calibrated according to the system characteristics, Q 气体 is the steam inlet flow rate, T 进汽口 is the steam inlet temperature, and T 目标温度 is the target temperature of the steam outlet.

[0089] According to the water pump specifications connected to the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower, determine the spray pressure of the standard medical waste steam cooling spray tower, which is the spray pressure of the spray head when the medical waste steam cooling spray tower performs spray liquefaction treatment by default in the system. According to the determined target spray flow parameter and target spray pressure parameter, the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower can be controlled to perform steam cooling spray treatment.

[0090] In an optional embodiment of the present invention, the medical waste steam cooling spray control method further includes:

[0091] Step 161: Receive the signal of the first in-tower pressure sensor of the first medical waste steam cooling spray tower or the signal of the second in-tower pressure sensor of the second medical waste steam cooling spray tower.

[0092] Step 162: When the signal of the first in-tower pressure sensor or the signal of the second in-tower pressure sensor is greater than the preset pressure threshold range or less than the preset pressure threshold range, increase or decrease the target spray pressure parameter and the target spray flow parameter of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower.

[0093] In this embodiment, the medical waste steam cooling spray control system monitors various parameters during the cooling spray process of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower in real time to ensure the stable and effective operation of the system. When an abnormal situation occurs, such as the packing layer 5 being blocked, resulting in an abnormal increase in the tower pressure. At this time, the medical waste steam cooling spray control system detects that the signal of the first tower pressure sensor or the second tower pressure sensor exceeds the preset pressure threshold range. At this time, the system automatically reduces the target spray pressure parameter and the target spray flow parameter of the spray device, reduces the liquid load, and prevents the pressure difference from further increasing. And triggers an alarm to prompt the maintenance personnel to perform emergency treatment.

[0094] In an alternative embodiment of the present invention, the medical waste steam cooling spray control method further includes:

[0095] Step 163, receiving the signal of the first steam outlet temperature sensor of the first medical waste steam cooling spray tower or the signal of the second steam outlet temperature sensor of the second medical waste steam cooling spray tower;

[0096] Step 164, when the signal of the first steam outlet temperature sensor or the signal of the second steam outlet temperature sensor is greater than or less than the preset temperature threshold range, increasing or decreasing the target spray flow parameter of the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower.

[0097] In this embodiment, when the system monitors that the temperature of the steam outlet of the medical waste steam cooling spray tower exceeds or is less than the preset temperature threshold range, it means that the treatment of the medical waste steam in the tower cannot achieve the preset effect at this time. When the steam outlet temperature is too high, the control system automatically increases the spray flow. At the same time, it monitors the pressure in the tower. If the pressure exceeds the preset pressure threshold range due to the increase in flow, the tower pressure sensor triggers the adjustment of the valve opening to maintain the pressure stability. When the steam outlet temperature is too low, the control system automatically reduces the spray flow to avoid wasting the pump power.

[0098] Such as Figure 2As shown, the medical waste steam cooling spray control system selects the medical waste steam cooling spray tower for this medical waste steam cooling treatment by controlling the opening and closing of the steam-liquid inlet valve. The real-time monitoring of the tower state and real-time feedback adjustment are realized by monitoring the signals fed back by various sensors and flow meters in the tower. The gas after cooling treatment in the first medical waste steam cooling spray tower or the second medical waste steam cooling spray tower is discharged from the tower through the steam outlet 21, while the condensed water after liquefaction treatment is discharged through the drain outlet 24 after filtering out impurities. At the same time, in this application, a secondary utilization circulating water pipeline connected to the drain outlets 24 of the two tower bodies is set up to collect the condensed water after cooling treatment in real time, realizing the recycling of water. The impurities filtered out from the condensed water flow into the sewage pipeline through the sewage outlet 41, realizing gas-liquid separation and dry-waste separation, and ensuring that each treatment link does not cross.

[0099] The medical waste steam cooling spray control method of the present invention realizes the precise liquefaction of medical waste steam according to the temperature of the steam outlet, meeting various liquefaction requirements of different degrees. At the same time, the operating state of the cooling tower is monitored in real time, including parameters such as temperature, pressure, and flow rate, and feedback adjustment is carried out according to the preset program. It can also control each component of the cooling tower, such as the start and stop of the spray device, the opening and closing of the valve, etc., and can realize the efficient and stable operation of the cooling tower and improve the cooling efficiency.

[0100] As Figure 3 shown, the embodiment of the present invention also provides a medical waste steam cooling spray system, including:

[0101] A steam-liquid pipeline;

[0102] The first medical waste steam cooling spray tower connected to the steam-liquid pipeline through the first steam-liquid inlet valve; and

[0103] The second medical waste steam cooling spray tower connected to the steam-liquid pipeline through the second steam-liquid inlet valve;

[0104] wherein, both the first medical waste steam cooling spray tower and the second medical waste steam cooling spray tower include:

[0105] Tower body 1;

[0106] A spray device extending into the top of the tower body 1;

[0110] In this embodiment, the tower body 1 is the main part of the device, used to accommodate steam, waste gas, and cooling water. The tower body 1 has sufficient strength and sealing performance to withstand the internal pressure and prevent the leakage of steam and waste gas. The material of the tower body 1 has good corrosion resistance and high temperature resistance to adapt to the high temperature environment during the medical waste treatment process.

[0111] A spray device is arranged at the top of the tower body 1. The spray device evenly sprays the cooling water into the medical waste steam, and the fluid fully exchanges heat with the cooling water to achieve cooling. In order to ensure the cooling effect, parameters such as the flow rate and pressure of the spray water can be adjusted according to the actual situation. At the same time, temperature sensors and pressure sensors can be arranged in the cooling tower to monitor the temperature and pressure changes during the cooling process in real time, so as to adjust the operating state of the cooling system in a timely manner.

[0112] The sewage discharge device is arranged at the bottom of the tower body 1. The liquefied condensed water is statically precipitated in the sewage discharge device to remove impurities therein. The sewage discharge device adopts a special structural design, which can make the fluid flow slowly to ensure that the impurities are fully precipitated. A combination of an inclined bottom plate and a guide plate can be used to guide the fluid to flow at a specific speed and direction. The precipitated impurities are regularly discharged through the sewage discharge device to keep the cooling tower operating normally.

[0113] The medical waste steam flows into the tower body 1 from the steam inlet 22, and is discharged from the steam outlet 21 after the cooling spray treatment. The liquefied condensed water falls to the bottom of the tower body 1, and after removing the precipitation, it flows into the secondary utilization circulating water pipeline from the drain outlet 24 to realize the recycling of water. The first liquid level meter port 23 and the second liquid level meter port 25 are used to install liquid level meters for monitoring the water level in the tower body 1.

[0116] An inlet 32 connected to the first end of the inlet pipe 31;

[0118] In this embodiment, the inlet pipe 31 is used to introduce cooling water into the device. The inlet pipe 31 has good corrosion resistance and pressure resistance to adapt to the harsh environment during medical waste treatment. The spray head 33 is one of the core components of the device, responsible for evenly spraying the cooling water into the steam and waste gas to achieve an efficient cooling effect. The spray head 33 adopts a special design that can generate fine water mist, increasing the contact area between the cooling water and the steam and waste gas, and improving the cooling efficiency. The number and arrangement of the spray heads 33 should be reasonably designed according to the size of the tower body 1 and the flow rates of the steam and waste gas to ensure the uniformity of the cooling effect.

[0119] In an alternative embodiment of the present invention, the sewage discharge device includes:

[0120] A sewage discharge port 41 extending into the bottom of the tower body 1;

[0121] A bottom plate and a flow guide plate 42 located at the top of the sewage discharge port 41.

[0122] In this embodiment, the sewage discharge port 41 is used to discharge the impurities and dirt accumulated in the tower body 1. The sewage discharge port 41 is provided at the bottom of the tower body 1 so that the impurities and dirt can be discharged smoothly. The bottom plate and the flow guide plate 42 can be inclined to guide the fluid to flow at a specific speed and direction, ensuring that the impurities are fully precipitated.

[0123] In an alternative embodiment of the present invention, the medical waste steam cooling spray system further includes:

[0124] A packing layer 5 and a demisting wire mesh 6 provided in the middle of the cavity of the tower body 1, and the packing layer 5 and the demisting wire mesh 6 are located between the steam outlet 21 and the steam inlet 22;

[0125] An overflow port 26 opened on the side wall of the tower body 1 and opposite to the drain port 24;

[0126] An impact plate 7 provided on the side wall of the tower body 1 and opposite to the steam inlet 22;

[0127] A steam inlet temperature sensor provided at the steam inlet 22, an outlet temperature sensor provided at the steam outlet 21, a tower internal temperature sensor and a tower internal pressure sensor provided inside the tower body 1, a spray pressure sensor and a spray flow meter provided inside the spray device, and a steam inlet flow meter provided at the steam inlet 22.

[0128] In this embodiment, the spraying device evenly sprays cooling water on the packing layer 5, and heat exchange occurs between the fluid and the cooling water in the packing layer 5 to achieve cooling. The packing layer 5 is made of efficient heat dissipation materials such as corrugated packing and ceramic packing, which have a large surface area and good heat transfer performance, and can improve the cooling efficiency.

[0129] The demisting wire mesh 6 is used to remove the water droplets and foam carried in the cooled waste gas. The demisting wire mesh 6 has good filtering performance and corrosion resistance, can effectively remove water droplets and foam, and prevent them from affecting the subsequent treatment equipment. The aperture and thickness of the demisting wire mesh 6 should be reasonably selected according to the flow rate of the waste gas and the size of the water droplets and foam.

[0130] The overflow port 26 is used to discharge the excess cooling water in the tower body 1. The overflow port 26 is arranged on the side wall of the tower body 1 to ensure that the cooling water will not accumulate too much in the tower body 1.

[0131] The impact plate 7 is installed inside the tower body 1 to prevent the steam and waste gas from impacting the inner wall of the tower body 1 and protect the inner wall of the tower body 1 from damage. The impact plate 7 has good corrosion resistance and high temperature resistance and can withstand the impact of steam and waste gas.

[0132] For the medical waste steam cooling and spraying system of the above embodiment of the present invention, since two tower bodies are provided and the double-tower cooling tower structure is used alternately in a cycle, the treatment capacity is greatly improved, meeting the large-scale cooling requirements. The cooling system realizes the heat exchange between the fluid and the cooling water through the spraying device and the efficient packing layer, improving the cooling efficiency. The sewage discharge device removes impurities to ensure the cooling effect and the normal operation of the equipment. Each tower body has an independent steam inlet 22, steam outlet 21, water inlet 32 and drain outlet 24, which is convenient for installation and maintenance operations, reducing the maintenance cost and time. The combination of the inclined bottom plate and the guide plate makes the fluid flow slowly, ensuring that the impurities are fully precipitated. The regular slag discharge port and the control device facilitate the discharge of impurities and maintain the performance of the cooling tower. The connecting pipe realizes the fluid circulation between the two tower bodies, and can adopt the pumping or natural circulation mode, and the best circulation mode is selected according to the actual situation to improve the system adaptability. The corrosion resistance and high temperature resistance of each component ensure long-term stable operation in a harsh working environment, improving the reliability and service life of the device.

[0133] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
