Description

Technical Field

[0001] The invention belongs to the field of drinking water production equipment, and in particular relates to a heating device for producing aged water. Background Art

[0002] After human society entered the industrial age, fresh water from rivers and streams in cities could no longer directly meet people's drinking needs. Along with industrialization, drinking water production technology has been developing. Both Chinese medicine, a treasure of China, and modern medicine believe that drinking boiled water, commonly known as hot water, is very beneficial to human health. The existing industrial technology for producing boiled water or boiled water usually requires filtration, heating, cooling, sterilization, and packaging, among which the heating process has a decisive influence on the taste of the boiled water. The heating equipment of the existing technology is usually only responsible for heating the filtered water once, and then enters the cooling process. The treatment of calcium and magnesium ions in the water is usually carried out by reverse osmosis filtration in the filtration process. Practice has proved that the boiled water (boiled water) produced by the existing technology can never reach the taste of the old boiled water obtained by the traditional Chinese family water boiling method. Summary of the invention

[0003] The object of the present invention is to provide a heating device for producing aged water, so that the magnesium ion content does not need to be adjusted by physical filtration to obtain aged water with traditional Chinese taste.

[0004] The technical solution for achieving the above-mentioned purpose includes the following contents.

[0005] A heating device for producing aged water, comprising an energy-gathering heat exchanger and a constant temperature cooking tank. The energy-concentrating heat exchanger is an indirect steam heat exchanger, including a production water inlet and outlet, a steam inlet and a condensed water outlet. The constant temperature cooking tank comprises a vertical round tank body, a steam coil and a stirring mechanism. A production water inlet and a pressure relief vent are arranged on the top of the round tank body. The bottom of the round tank body is in an inverted cone shape, and a production water outlet is arranged in the center of the bottom. The steam coil is coiled around the outer wall and the bottom of the round tank body from top to bottom. The upper end of the steam coil is a steam inlet, and the lower end is a condensed water outlet. The stirring mechanism comprises an agitator and a drive motor. The drive motor is arranged above the round tank body. The agitator comprises a stirring shaft and a stirring impeller. The stirring shaft is arranged vertically. The upper part of the stirring shaft passes through the center of the top of the round tank body. The top end of the stirring shaft is connected to the driving motor. A plurality of stirring impellers are arranged at intervals along the up and down directions on the stirring shaft. The production water outlet of the energy-concentrating heat exchanger is lower than the production water inlet on the top of the round tank body, and the two are connected through a heat dissipation pipe.

[0006] Furthermore, the bottom height of the inverted cone shape is 1 / 8 to 1 / 6 of the height of the round can body.

[0007] Furthermore, the length of the stirring shaft inserted into the round tank body is greater than 1 / 2 of the height of the round tank body.

[0008] Furthermore, the diameter of the stirring impeller is 1 / 4 to 1 / 2 of the inner diameter of the round tank body.

[0009] When the above heating device for producing aged water is used, the production water inlet of the energy-gathering heat exchanger is connected to the water outlet of the filtering device. The filtering device does not need to be provided with a reverse osmosis filter module. High-temperature steam (above 160°C) is input into the energy-gathering heat exchanger. The production water exchanges heat with the high-temperature steam in the energy-gathering heat exchanger. The water temperature of the production water quickly reaches above the boiling point, causing the calcium and magnesium ions in the production water to quickly precipitate and remain in the energy-gathering heat exchanger. After the high-temperature (gaseous) production water flows out of the energy-gathering heat exchanger, it is cooled while ascending along the heat dissipation pipe. The production water restored to liquid state (high-temperature water above 98°C) enters the constant temperature cooking tank. The high-temperature steam is injected into the steam coil. The high-temperature steam continuously heats the production water in the round tank body, so that the water temperature of the production water in the round tank body is kept above 99°C for a long time. The cooking duration reaches 0.5-168 hours. During the continuous heating process, the agitator continuously stirs so that the production water in the tank body is evenly heated. After reaching the specified cooking time, the production water has become cooked water and is discharged from the outlet of the cooking tank to reach the next cooling process.

[0010] The heating device for producing aged water of the present invention uses two heating components to heat the produced water twice in succession. The former energy-gathering heat exchanger quickly heats the produced water to above the boiling point, which can achieve the effect of precipitating calcium and magnesium ions. The latter constant temperature cooking tank continuously cooks the produced water for a long time, further adjusting the water pH. The present invention uses high-temperature heating to separate calcium and magnesium ions, which is different from the reverse osmosis filtration method used in the prior art. The aged water obtained by the present invention is closer to the taste of the traditional aged water cooked in Chinese families, and has a better mouthfeel than the cool white produced by the prior art.

[0011] It should be noted that it does not require creative work for those skilled in the art to install a temperature control device (such as increasing or decreasing the steam flow rate) on the constant temperature cooking tank and the energy-concentrating heat exchanger so that the working substance reaches a temperature that meets the requirements, and this case does not elaborate on the relevant temperature control device.

The energy-concentrating heat exchanger 2 is an indirect steam heat exchanger, including a production water inlet and outlet, a steam inlet and a condensed water outlet. The constant temperature cooking tank 1 includes a vertical round tank body, a steam coil 5, and a stirring mechanism 4. A production water inlet and a pressure relief vent are provided on the top of the round tank body. The bottom of the round tank body is in an inverted cone shape. The inverted cone bottom 1-1 is conducive to improving the pressure bearing capacity of the tank body and is also conducive to sedimentation. At the same time, it plays a good guiding role in the flow of production water during stirring. The round tank body of this embodiment is 6500mm high, the inner diameter of the round tank body is 2900mm, the bottom cone angle is 120°, and a production water outlet is provided in the center of the bottom; the steam coil 5 is coiled around the outer wall and the bottom of the round tank body from top to bottom, the upper end of the steam coil 5 is a steam inlet, and the lower end is a condensed water outlet; the stirring mechanism 4 includes an agitator and a drive motor 3. The drive motor 3 is deployed above the round tank body. The agitator includes a stirring shaft 4-1 and a stirring impeller 4-2. The stirring shaft 4-1 is vertically arranged The upper part of the stirring shaft 4-1 passes through the center of the top of the round tank body, the length of the stirring shaft 4-1 inserted in the round tank body is 5500mm, the top of the stirring shaft 4-1 is connected to the driving motor 3, and a stirring impeller 4-2 is arranged at the bottom and the middle of the stirring shaft 4-1. The diameter of the stirring shaft 4-1 is 105mm, and the diameter of the stirring impeller 4-2 is 1000mm. The production water outlet of the energy-concentrating heat exchanger 2 is lower than the production water inlet at the top of the round tank body, and the two are connected by a heat dissipation pipe 6.

[0016] The heating device for producing aged water is arranged between the filtering device and the cooling device. The production water inlet of the energy-gathering heat exchanger 2 is connected to the water outlet of the filtering device. There is no need to set a reverse osmosis filtering module in the filtering device. High-temperature steam (above 160°C) is input into the energy-gathering heat exchanger 2. The production water performs indirect heat exchange with the high-temperature steam in the energy-gathering heat exchanger 2. The water temperature of the production water quickly reaches above the boiling point, causing the calcium and magnesium ions in the production water to quickly precipitate and remain in the energy-gathering heat exchanger 2. After the high-temperature (gaseous) production water flows out of the energy-gathering heat exchanger 2, it is cooled while ascending along the heat dissipation pipe 6. The production water restored to liquid state (high-temperature water above 98°C) enters the constant temperature cooking tank 1. The high-temperature steam is injected into the steam coil 5. The high-temperature steam continuously heats the production water in the round tank body, so that the water temperature of the production water in the round tank body is maintained at a temperature above 99°C for a long time. The cooking duration reaches 0.5-168 hours. During the continuous heating process, the agitator continuously stirs so that the production water in the tank body is evenly heated. After reaching the specified cooking time, the produced water has become cooked water, which is discharged from the outlet of the cooking tank and transported to the subsequent cooling equipment.

[0017] The heating device for producing aged water in this embodiment uses two heating components to heat the produced water twice in succession. The former energy-gathering heat exchanger 2 quickly heats the produced water to above the boiling point, which can achieve the effect of precipitating calcium and magnesium ions. The latter constant temperature cooking tank 1 cooks the produced water for a long time at a temperature close to the boiling point, further adjusting the water pH. The present invention uses high-temperature heating to separate calcium and magnesium ions, which is different from the reverse osmosis filtration method used in the prior art. The aged water obtained by the present invention is closer to the taste of the traditional aged water cooked by Chinese families, has a better mouthfeel than the cold white produced by the prior art, and is more in line with the taste of the Chinese people.
