Description

Technical Field

[0001] The invention relates to an industrialized method and equipment for rapidly and efficiently preparing ozone ice, belonging to the technical field of ozone ice. Background Art

[0002] Ozone has poor stability at room temperature and pressure, and it is easy to decompose into oxygen by itself, making it difficult to preserve. Studies have found that ozone is relatively stable in ice water close to 0°C, especially in ice cubes, with a half-life of up to 2000 years. The method of making ozone ice in the prior art is generally: using an ozone generator to convert oxygen into ozone, then using a gas-water mixing device to dissolve ozone in water, and finally passing it through a rapid freezing system to make it into ice cubes containing ozone. However, due to the rapid decomposition rate of ozone in water, this process has defects such as difficulty in controlling parameters such as concentration. Although the existing patented technology (Patent 201510716740.X A method for industrial production of ozone ice) solves the problem of ozone ice production parameters, the freezing time of ozone ice produced by this process is long, generally requires freezing for several hours, and requires the production environment temperature to be below -20°C.

[0028] like Figure 1-2 An industrially fast and efficient device for preparing ozone ice is shown, comprising a storage tank 1, a booster pump 2, a blower 3, an atomizing jet device 4, a gas-solid separator 5, a water-cooled heat exchanger 6, a gas-liquid mixer 7, an ozone generator 8, an absorption tower 9, an ozone ice crystal collection device 10, an air-cooled heat exchanger, a refrigerator and a pure water source 11, wherein the storage tank 1 comprises a tank body, the top of the tank body is provided with an exhaust port 1004, the lower part of the tank body is provided with a first liquid inlet 1001 and a second liquid discharge port 1003, the first liquid inlet 1001 is located below the first liquid discharge port 1002, the atomizing jet device 4 is provided with a second liquid inlet, an air inlet and a first output end, the first liquid discharge port 1002 is connected to the input end of the booster pump 2, the output end of the booster pump 2 is connected to the second liquid inlet, the air suction port of the blower 3 is connected to the The exhaust port 1004 is connected, the air intake port of the blower 3 is connected to the output end of the air-cooled heat exchanger, the air outlet of the blower 3 is connected to the air inlet, the first output end is connected to the input end of the gas-solid separator 5, the top of the gas-solid separator 5 is connected to an absorption tower 9 for collecting ozone tail gas, the lower part of the gas-solid separator 5 is connected to an ozone ice crystal collection device 10 for collecting ozone ice crystals, the input end of the ice crystal collection device 10 is connected to the discharge port of the gas-solid separator 5, the absorption tower 9 is connected to the exhaust port of the gas-solid separator 5, the ice crystal collection device 10 in this embodiment includes an ice compressor and a refrigeration device, the discharge port of the gas-solid separator 5 is connected to the input end of the ice compressor, the ice compressor compresses the ozone ice crystals to form an ozone ice crystal block, and then the obtained ozone ice crystal block is transferred to the refrigeration device. In this embodiment, the air temperature output by the air-cooled heat exchanger is 0-4°C.

[0029] like Figure 2 The atomizing jet device 4 shown includes a housing 41, the housing is provided with a first tapered hole section 42, a second tapered hole section 43, and a transition section between the first tapered hole section 42 and the second tapered hole section 43, the transition section is equipped with a plurality of nozzles 44, the input end of the transition section is connected to the smallest end face of the first tapered hole section 42, the output end of the transition section is connected to the smallest end face of the second tapered hole section 43, the second liquid inlet is located on the housing 41, the second liquid inlet is connected to the nozzle 44, the air inlet is located at the input end of the first tapered hole section 42, and in this embodiment, the first output end is the large end face of the second tapered hole section 43. The ratio of the taper of the first tapered hole section 42 to the taper of the second tapered hole section 43 is greater than 1.2, the flow rate of the first mixed gas through the air inlet is a, and the flow rate of the pressurized ozone water through the second liquid inlet is b, wherein a:b>50:1, wherein the preferred ratio is 200-500:1. In the atomizing jet device, the pressurized ozone water is atomized into ozone water droplets by the nozzle, and the first mixed gas is ejected at high speed from the first conical hole section 42. The first mixed gas is compressed in the first conical hole section 42, and the temperature and pressure are increased. When passing through the transition section, the ozone water droplets are quickly mixed with the first mixed gas ejected at high speed from the first conical hole section 42 to form a first mixture. When the first mixture is ejected into the second conical hole section 43, since the taper of the second conical hole section 43 is smaller than that of the first conical hole section 42, as the inner diameter of the second conical hole section 43 increases, the ozone water droplets are compressed ... first mixed gas is compressed. The gas pressure and temperature drop suddenly, the surface of the ozone water droplets quickly liquefies, and at the same time absorbs a large amount of vaporization heat from the inside of the droplets, thereby quickly reducing the temperature of the ozone water droplets, causing them to quickly solidify into ozone ice crystals. The ozone ice crystals are ejected out of the atomizing jet device 4 along with the first mixed gas. In the present invention, since the first mixed gas contains a certain concentration of ozone gas, the amount of ozone overflow from the ozone water droplets during the solidification process can be reduced, which is beneficial to maintaining the concentration of ozone in the ozone ice, while effectively utilizing the tail gas, reducing the waste of ozone, and improving production efficiency.

[0030] As a preferred solution, the second liquid discharge port 1003 is connected to the water-cooled heat exchanger 6, and the input end of the water-cooled heat exchanger 6 is also connected to the pure water source 11. The ozone water and the pure water are added to the water-cooled heat exchanger 6 according to a volume ratio of 1:1. The water-cooled heat exchanger 6 mixes the ozone water and the pure water to form low-temperature return water after cooling. The output end of the water-cooled heat exchanger 6 inputs the low-temperature return water into the gas-liquid mixer 7. At the same time, the high-concentration ozone gas generated by the ozone generator 8 has an ozone concentration greater than 150 mg / L. The output end of the ozone generator 8 is connected to the input end of the gas-liquid mixer 7, and the ozone gas is mixed with the low-temperature return water to form the first The output end of the gas-liquid mixer 7 is connected to the first liquid inlet 1001 to input the first mixed solution into the storage tank; in addition, an ozone concentration analyzer, a liquid level meter, and a temperature controller are installed in the storage tank to achieve precise control of the temperature of the ozone water, the replenishment flow rate, and the ozone concentration in the ozone ice, ensuring that the concentration of the ozone water in the storage tank 1 remains unchanged. When the concentration of the ozone water increases or decreases, the concentration of the ozone water in the gas-liquid mixer 7 can be adjusted, that is, the amount of low-temperature return water output by the water-cooled heat exchanger 6 or the amount of ozone gas output by the ozone generator 8 is adjusted, so that the concentration of the ozone water in the storage tank 1 remains consistent. In the present invention, the storage tank uses the water-cooled heat exchanger 6 and the gas-liquid mixer 7 to make the ozone water concentration temperature in the storage tank 1, and the temperature of the ozone water is maintained at 0-4 degrees Celsius. The user can adjust the ozone water concentration in the water storage tank by adjusting the power of the ozone generator, thereby controlling the ozone concentration in the ozone ice.

[0031] At the same time, the low-temperature air input to the blower is cooled by an air-cooled heat exchanger, and the low-temperature return water is cooled by a water-cooled heat exchanger, and the air-cooled heat exchanger and the water-cooled heat exchanger are both connected to the refrigerator. In the entire system, the load of the refrigerator is only used to cool the air and the low-temperature return water, and is not directly used in the entire process of ozone ice production. Therefore, compared with the existing technology, the power load required for refrigeration can be greatly reduced, and the energy consumption is lower.

[0032] The gas-liquid mixer 7 described in this embodiment can be a gas-liquid mixing pump (Nikoni pump), a jet aerator (Venturi tube), or a micro-nano bubble generating device.

[0033] Implementation II

[0034] A method for industrially rapidly and efficiently preparing ozone ice, comprising:

[0035] Step 1, the storage tank 1 stores ozone water, the booster pump 2 sucks the ozone water out from the first liquid discharge port 1002 of the storage tank 1 and pressurizes it, and the booster pump 2 outputs the pressurized ozone water;

[0036] Step 2, the blower 3 absorbs the tail gas from the storage tank. At the same time, the blower 3 absorbs the low-temperature air output by the air-cooled heat exchanger. The tail gas and the low-temperature air are mixed into a first mixed gas in the blower 3. The blower 3 pressurizes the first mixed gas and outputs it.

[0037] Step 3, the pressurized ozone water enters the atomizing jet device 4 from the second liquid inlet, and the first mixed gas enters the atomizing jet device 4 from the air inlet at the same time, the pressurized ozone water and the first mixed gas become a first mixture in the atomizing jet device 4, and the first mixture becomes a second mixture in the atomizing jet device 4. Specifically, the pressurized ozone water enters the nozzle 44 of the atomizing jet device 4 from the second liquid inlet, the nozzle 44 sprays the pressurized ozone water in an atomized form, and the first mixed gas enters the first tapered hole section 42 from the air inlet, the pressurized ozone water and the first mixed gas are mixed in the transition section, and become the second mixture in the second tapered hole section 43;

[0038] In step 4, the second mixture is sprayed into the gas-solid separator 5, and the second mixture is separated into ozone ice crystals and the first mixed gas in the gas-solid separator 5.

[0039] As a preferred solution, in step 1, the ozone water and the pure water in the storage tank 1 are simultaneously input into the water-cooled heat exchanger 6 for mixing and cooling, the water-cooled heat exchanger 6 outputs low-temperature return water, the ozone generator 8 outputs ozone gas, the low-temperature return water and the ozone gas are mixed in the gas-liquid mixer 7, the gas-liquid mixer 7 outputs a first mixed liquid, and the first mixed liquid enters the storage tank 1 from the first liquid inlet 1001;

[0040] In step 3, the blower 3 delivers the first mixed gas to the atomizing jet device 4 through a pipeline;

[0041] In step 4, ozone ice crystals fall into the ice crystal collecting device in the gas-solid separator 5, and the first mixed gas is discharged from the top of the gas-solid separator 5 and collected by the absorption tower.

[0042] As a preferred solution, in step 1, the volume ratio of ozone water to pure water added to the water-cooled heat exchanger 6 is 1:1, the temperature of the low-temperature return water is 0-4°C, and the concentration of ozone gas generated by the ozone generator 8 is >150mg / L;

[0043] In step 2, the temperature of the low-temperature air is 0-4°C, and the volume ratio of the first mixed gas to the exhaust gas is greater than 50:1;

[0044] In step 3, the air pressure of the first mixed gas is 10-70 KPa.

[0045] When the low-temperature return water is lower than 0℃, first, the ozone water will freeze in advance, which is not conducive to the transportation of pipelines and pumps, thus affecting the continuous production of ozone ice, and also increasing the energy consumption for refrigeration. Secondly, in an environment below 0℃, the cold water will freeze before dissolving the ozone, and the ice cannot dissolve the ozone, thereby reducing the concentration and quality of the ozone ice. As can be seen from the table below, as the temperature rises, the freezing time of ozone ice crystals increases and the ozone concentration in the exhaust gas increases. Although the production capacity of ozone ice crystals at 10℃ (i.e., the output of ozone ice crystals per hour) increases, the ozone concentration in ozone ice crystals decreases at 10℃, and the ozone content in the generated ozone ice crystals is much lower than that of the ozone ice crystals generated at 0℃ and 4℃. Therefore, this implementation preferably selects 0-4℃, the production capacity of ozone ice crystals is stable at 1kg / h, and the ozone concentration in ozone ice crystals is higher.

[0046] Table 1 shows the ozone solubility, power load, freezing time, ozone concentration in ozone ice crystals, and production capacity at different temperatures.

[0047]

[0048] Note: This table takes standard equipment with a production capacity of 1 ton / hour as an example.

[0049] High air pressure can speed up the freezing process, but the energy consumption of the blower will increase. Moreover, the blower cannot achieve an air pressure of more than 70kPa. According to experiments, when the pressure is less than or equal to 10KPa, ozone ice crystals cannot form; when the pressure is equal to 20KPa, the formation time of ozone ice crystals is 0.7s; when the pressure is equal to 20KPa, the formation time of ozone ice crystals is 0.7s; when the pressure is equal to 50KPa, the formation time of ozone ice crystals is 0.5s; when the pressure is equal to 70KPa, the formation time of ozone ice crystals is 0.4s. The preferred pressure range of the present invention is 20KPa-70KPa.

[0050] During the solidification process of ozone water droplets, the volume ratio of the first mixed gas to ozone water has a great influence on the formation time of ozone ice crystals and the ozone concentration in the ozone ice crystals. The test found that under standard conditions, when the ratio of the first mixed gas to pressurized ozone water is 50:1, ozone ice crystals cannot be formed; when the ratio of the first mixed gas to pressurized ozone water is 100:1, the formation time of ozone ice crystals is 0.6s, and the ozone concentration in the ozone ice crystals is 14ppm; when the ratio of the first mixed gas to pressurized ozone water is 200:1, the formation time of ozone ice crystals is 0.4s, and the ozone concentration in the ozone ice crystals is 2 0ppm; when the ratio of the first mixed gas to pressurized ozone water is 500:1, the formation time of ozone ice crystals is 0.2s, and the ozone concentration in the ozone ice crystals is 25ppm; when the ratio of the first mixed gas to pressurized ozone water is 1000:1, the formation time of ozone ice crystals is 0.1s, and the ozone concentration in the ozone ice crystals is 30ppm; as the volume of the first mixed gas increases, the formation time of ozone ice crystals becomes shorter, and the ozone concentration in the ozone ice crystals increases, but as the volume ratio of the first mixed gas increases, the required wind speed becomes larger, and the energy consumption will also increase. The preferred ratio in this embodiment is 200-500:1.
