Description

Technical Field

[0001] The utility model relates to the technical field of fresh air humidification and water replenishment pre-treatment devices, in particular to a fresh air humidification and water replenishment pre-treatment device for a five-constant system. Background Art

[0002] The Wuheng system uses the principle of independent temperature and humidity control to achieve controllable temperature and humidity in the indoor environment, while solving the need for indoor ventilation. When operating in summer, the humidity content of outdoor air is significantly higher than the indoor and body comfort range, so dehumidification is required. Similarly, when operating in winter, the humidity content of outdoor air is significantly lower than the indoor and body comfort range, so the outdoor air needs to be humidified before being sent indoors.

[0003] Among the current five-constant system solutions, the most commonly used equipment is the wet film humidifier installed in the fresh air equipment. Its principle is to use water to wet the membrane material, increase the surface area and evaporation efficiency per unit of water, and the vaporized water is brought into the room by the preheated fresh air, thereby humidifying the indoor environment. Compared with other types of fresh air system humidifiers, wet film humidifiers have the advantages of low cost, low energy consumption, and low water quality requirements, but they also have disadvantages such as low vaporization efficiency and high water consumption. Among them, improving the vaporization rate is the key to improving the effect of wet film humidifiers.

[0004] The factors affecting the efficiency of wet film humidifiers mainly include the following:

[0005] (1) Water infiltration in wet film

[0006] Only by humidifying and replenishing water to fully soak the wet film can a better humidification effect be achieved. For the finalized wet film humidifier, its water distributor has been finalized, and the main influencing factors are only two aspects:

[0007] First, the amount of water to be replenished. If the amount of water to be replenished is too small, the wet membrane cannot be fully infiltrated, affecting the contact area between air and water, thus affecting the humidification effect; but if the amount of humidification water is too large, poor drainage will lead to the risk of equipment leakage, while increasing water consumption and energy consumption. Traditional wet film humidification equipment requires manual adjustment of the valve opening to achieve flow control, but because of the pressure fluctuations of tap water itself, it is more difficult to control the amount of water to be replenished.

[0008] Second, the water absorption capacity of the wet film. The wet film has good water absorption capacity when it leaves the factory and can be fully infiltrated. However, with use, calcium and magnesium ions precipitate and harden on the wet film, which will affect the water absorption performance of the wet film, and then affect the degree of infiltration and humidification effect.

[0009] (2) Humidification water supply temperature

[0010] In my country, the demand for humidification usually occurs in winter when the temperature is cold and the tap water temperature is low. Relying solely on fresh air to heat the water distributed on the wet membrane has a low heating efficiency. Appropriately increasing the humidification water replenishment temperature can improve the humidification efficiency.

[0011] The fresh air humidification and water replenishment pre-treatment device for which a patent is to be applied for mainly improves the humidification capacity of the wet-film humidifier of the fresh air fan of the Wuheng system through technical means and their control, such as humidification flow limitation, humidification water replenishment preheating, and humidification water replenishment scale prevention treatment. The device is installed independently and has no restrictions on the wet-film equipment. Utility Model Content

The electric heating belt body 7 is fixedly installed on one side of the KDF55 alloy scale inhibitor 5. The electric heating belt body 7 generates heat to convert electrical energy into thermal energy.

[0030] Furthermore, a water supply inlet joint 9 is fixedly installed on the top of the electric switch valve body 4 and extends to the top of the installation box 1, and a water supply pipe 10 is fixedly installed on the bottom of the electric switch valve body 4. The water supply pipe 10 is made of a carbon steel pipe. The water supply pipe 10 is fixedly connected to the KDF55 alloy scale inhibitor 5, and a water supply outlet joint 11 is fixedly installed on one side of the flow limiting tube 8 and on one side of the installation box 1.

[0031] Furthermore, a chip temperature sensor body 12 is fixedly installed on one side of the electric heating belt body 7. The chip temperature sensor body 12 is based on the principle of a resistance thermometer, that is, it uses the influence of the temperature change of a material on its resistance value to measure the temperature. An AC220V power plug 13 is fixedly installed on the top of the installation box 1, and a pre-processing device power supply line 14 is fixedly installed at the bottom of the AC220V power plug 13 and extends to the interior of the installation box 1.

[0032] Furthermore, an electric switch valve supply neutral line 15 is fixedly installed on one side of the DC24V direct power supply 2, an electric switch valve supply live line 16 is fixedly installed below the electric switch valve supply neutral line 15 and inside the installation box 1, and an electric switch valve control line 17 is fixedly installed on one side of the electric switch valve supply live line 16.

[0035] To sum up: the humidification and water replenishment pipe is connected to the water replenishment inlet joint 9, the humidification and water replenishment enters the pretreatment device through the water replenishment inlet joint 9 and flows in the water replenishment pipe 10. The water replenishment pipe 10 in this device is made of metal. Except for the part covered by the electric heating belt body 7, it needs to be insulated. The on and off of the humidification and water replenishment is controlled by the switch of the electric switch valve body 4, thereby controlling the on and off of the humidification and water replenishment of the five-constant system fresh air fan, and then controlling the switch of the humidification function of the fresh air fan. The humidification and water replenishment are treated with scale in the KDF55 alloy scale inhibitor 5. The scale prevention treatment utilizes the material properties of the KDF55 alloy filler 6 inside it, which can change the crystal form of calcium and magnesium ions after precipitation, and transforms it from hard, low-solubility calcite crystal needle-shaped crystals into irregular forms, thereby The humidification water supply pipe 10 is installed close to the water supply pipe 10, and the problem of limited humidification capacity caused by low humidification water supply temperature in winter is solved by using the electric heating belt body 7. The humidification water supply pipe 8 is limited by the flow of current limiting pipe 8 after being heated by the electric heating belt body 7. The flow of current limiting pipe 8 can supply water at a constant flow rate and is little affected by the tap water pressure. The flow of current limiting pipe 8 is based on the wet film humidification of the new air fan of the five constant systems served. The device is required to be selected. The use of the current limiting tube 8 solves the problem that the humidification and water replenishment water volume is difficult to control due to water pressure changes and human factors during debugging. The humidification and water replenishment pipeline 10 of the Wuheng system fresh air fan is connected to the water replenishment outlet joint 11. The humidification and water replenishment processed by the pre-treatment device enters the wet film humidifier of the Wuheng system fresh air fan through the water replenishment outlet joint 11. The power supply for all electrical equipment of the pre-treatment device is provided by the AC220V power plug 13 and the pre-treatment device power supply line 14. The weak power supply in the controller 3 is provided by the DC24V direct current power supply 2 after being converted into direct current. The controller 3 realizes the signal acquisition and logic operation processing of the required sensors, and sends control instructions to the controlled equipment. Its power consumption is provided by the DC24V direct current power supply 2, external temperature and humidity sensor 24 is an external device installed in the fresh air fan of the Wuheng system or in the air supply duct connected thereto. It can be powered by the temperature and humidity sensor power supply line 21, or powered by electricity nearby. The temperature and humidity signals collected by it are transmitted to the controller 3 by the temperature and humidity sensor communication line 22. The controller 3 calculates the dew point temperature by the temperature and humidity measured by the external temperature and humidity sensor 24 and compares it with the set value. If the set value is not reached, the electric switch valve body 4 is opened, otherwise the electric switch valve body 4 is closed, thereby controlling the on and off of the humidification and water replenishment of the fresh air fan of the Wuheng system, and then controlling the switch of the humidification function of the fresh air fan. The control signal of the electric switch valve body 4 is sent down through the electric switch valve control line 17. The patch temperature sensor body 12 is installed close to the water replenishment pipeline 10 and is located downstream of the electric heating belt body 7.The collected temperature signal is transmitted to the controller 3 by the communication line 23 of the patch temperature sensor, and the controller 3 compares it with the set temperature to determine whether to turn on the heating function. The signal is sent to the electric heating belt body 7 through the electric heating belt control line 20. In particular, when the electric switch valve body 4 is in the closed state, the heating function is not turned on regardless of whether the preset temperature is reached. The pre-processing device can be used independently or in conjunction with the new air blower of the five-constant system. If it is necessary to use it in conjunction, an additional linkage control line needs to be connected to the controller 3.
