Description

Technical Field

[0001] The invention relates to the field of domestic sewage treatment, and in particular to a water vapor condensation water collection analysis device and an analysis method. Background Art

[0002] The water in the atmosphere mainly exists in the form of liquid water and gaseous water. When the temperature drops below zero, solid water will be produced. Under different temperature and pressure conditions, water can be converted between different phases through processes such as vaporization and liquefaction. According to the relative relationship between the liquefaction rate and the vaporization rate, the water vapor state in the air can be divided into the following three types, namely, unsaturated state, saturated state, and supersaturated state. The relative humidity of the unsaturated state is less than 100%, and its vaporization rate is greater than the liquefaction rate; the relative humidity of the saturated state is equal to 100%, and its vaporization rate is equal to the liquefaction rate; and the relative humidity of the supersaturated state is greater than 100%, and its vaporization rate is less than the liquefaction rate, that is, condensed water is generated. The water vapor conversion rate is mainly affected by temperature, pressure and water vapor density. The water vapor density can be expressed by relative humidity. In order to quickly achieve the conversion between water vapor under known conditions, if the air temperature, air pressure and relative humidity are known, what kind of condensation temperature should be adopted to quickly complete the conversion from gas to water, and the corresponding water vapor conversion equation should be obtained. In order to obtain the water vapor conversion equation, a corresponding analytical experimental device is required. Summary of the invention

[0029] The implementation method of this embodiment is that the ultimate purpose of this water vapor condensation water collection and analysis device is to obtain a water vapor saturation equation to obtain the temperature that can make it reach saturation as quickly as possible under the existing relative humidity and temperature conditions. Therefore, we need to obtain the corresponding water vapor saturation equation by setting variables and invariants; the main factors affecting the water vapor conversion rate are temperature, air pressure, water vapor density and condensation temperature, and the water vapor density can be indirectly expressed by relative humidity. The specific operation is as follows:

[0030] Step 1, turn on the air pump 3, and introduce the air with an initial temperature of 10°C and a relative humidity of about 80% into the collection cabin 1. When the value of the pressure tester 5 in the cabin is one atmosphere, the air guide stops. At the same time, read and record the value of the air flow meter 4, that is, the volume of gas entering the box. After that, gradually lower the temperature of the semiconductor refrigeration plate 7 until the relative humidity reading is 100%, and keep the relative humidity stable. The equipment automatically records the temperature value in the box. After a period of time, measure the amount of liquid water generated in the water storage device. Thereafter, introduce air with initial temperatures of 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C and a relative humidity of about 80% in turn and record the above data in turn.

[0031] Step 2, turn on the air pump 3, and introduce air with an initial relative humidity of 30% into the collection cabin 1. When the value of the pressure tester 5 in the cabin is one atmosphere, the air guide stops, and the air temperature is recorded at the same time. The value of the air flow meter 4 is read and recorded. After that, gradually lower the temperature of the semiconductor refrigeration plate 7 until the relative humidity reading is 100%, and stop when the relative humidity is kept stable, and record the temperature value in the collection cabin 1. After a period of time, measure the amount of liquid water generated. Thereafter, introduce air with relative humidity of 40%, 50%, 60%, 70%, 80%, 90% and 95% into the collection cabin 1 in turn, and record the above data in turn;

[0032] Step 3: Turn on the air pump 3, guide the wet air into the collection cabin 1, gradually adjust the temperature of the semiconductor cooling plate 7 until the relative humidity readings are 100%, 105%, 110%, 115%, and 120%, respectively, and keep the relative humidity stable, and record the temperature and air pressure values ​​in the box. When the value of the cabin pressure tester 5 is one atmosphere, the air guide stops, and at the same time, read and record the values ​​of the air flow meter 4 and the cabin pressure tester 5. After a period of time, measure the amount of liquid water generated.

[0033] Step 4: The water vapor condensation water collection analysis device analyzes the relationship between saturation temperature and water vapor content under different conditions, and performs fitting analysis to obtain the saturated water vapor equation. This equation can directly calculate the saturation temperature based on the known initial conditions, that is, the temperature can be directly controlled to make it saturated quickly. At the same time, the amount of liquid water generated under different air pressure conditions is analyzed to improve the efficiency of liquid water generation.

[0034] After the experiment is completed, open the exhaust plug 11 to discharge the waste, and then open the drain hole cover to release the water.
