detailed description

The following describes the technical solutions of some embodiments of the utility model according to the drawings provided by the utility model.

One of the embodiments of the present utility model provides a family indoor air purification device. The structure of the liquid filtering air purification box used is shown in Figure 1, referred to as the purification box; the purification box and a compression fan constitute the family indoor air purification device , as shown in Figure 2, referred to as liquid filter air purification device. The structure and working principle of this family indoor air purification device are described as follows:

1. The main structure of the purification box includes the shell of the purification box (1), the filter liquid injection port (2), the filter liquid discharge switch (3), the air inlet of the purification box (4), the lower elbow (5), and the screen filter (6), the gas-liquid separator (8), and the gas outlet of the purification box (11) are composed of several parts. The working principle is to use liquid, such as water, as the filtrate, place the screen filter (6) below the level of the filtrate (7), and the air will be purified from the air under the negative pressure formed by the compression fan (14). The air inlet of the box (4) enters the air filter cavity (9) through the lower elbow (5), emerges upwards through the small holes of the screen filter (6), and enters the purified air storage chamber (10) after contacting with the filtrate and filtering , and then discharged through the air outlet (11) of the purification box. At this time, it is fresh air that has been purified by "washing".

The purification box can be designed in various shapes and sizes, and can be made of various materials, such as plastics and metal materials.

If this system is placed in a family room, the air in the room will be purified after a certain working time. This method can not only effectively remove smog pollutants in the room, but also effectively remove harmful gases such as formaldehyde, because formaldehyde is easily soluble in water. There are many advantages to using clean water as the filter liquid. First, it is cheap and convenient, and can be replaced at any time; second, the air filtration effect is clear at a glance, and polluted air will make the clean water turbid; third, in order to improve the purification effect, it can be put into the water if necessary. Additives and must not be harmful to the human body, such as disinfectant ingredients. In addition to clean water, the filtrate can also be other types of liquids.

For the above-mentioned implementation, the so-called compression exhaust fan (14) is an air compressor or blower, which has an air inlet pipe and an air outlet pipe. In order to increase safety and practicality, the compression exhaust fan (14) can be controlled by an intelligent control device, which can be used for timing start-up and shutdown control, automatic air supply at certain time intervals, and power supply protection and safety control.

For the above implementation situation, the room is required to close the doors and windows to avoid ventilation in the room, otherwise polluted air will continuously pour in from the outside, and the purification effect will not be achieved.

2. In the above and related embodiments, according to the size and shape of the clean box shell (1), the screen filter (6) is processed into a square or circular planar body with tiny vent holes, and the clean box shell ( 1) Close contact forms a partition, and a filter chamber (9) is formed below the partition to ensure that the gas can only emerge upward through its small holes. The gas-liquid contact area can be controlled by using the diameter of the vent hole, thereby improving the transient purification rate . The so-called transient purification rate refers to the rate at which the air pollution components are reduced after the air passes through the purification box once.

The advantage of adopting the planar structure of the screen filter (6) is that it is convenient for processing and forming, and it makes disassembly and cleaning operations simple.

The screen filter (6) has a single-layer or multi-layer structure. When a multi-layer structure is adopted, the gas-liquid contact time can be prolonged by increasing the distance between layers, thereby improving the transient purification rate and increasing the air filtration effect.

3. In the above and related embodiments, the filtrate, such as clean water, can be added to the purification box through the filtrate injection port (2) to a certain height, and the filtrate injection port (2) is equipped with a sealing cover. Close the sealing cap tightly. After the filtrate is polluted, use the filtrate discharge switch (3) to discharge, and then replace with fresh filtrate. Adding a filtrate injection port (2) and a filtrate discharge switch (3) on the purification box is beneficial to increase the convenience of maintenance.

4. In the above and related embodiments, a gas-liquid separator (8) is installed above the filtrate level (7) inside the purification box shell (1). The gas-liquid separator (8) is a flat filter layer made of air-permeable fiber material, which has the function of recovering the filtrate and preventing the filtrate from entering the purified gas storage chamber (10). When the gas-liquid separator (8) is installed, a certain inclination angle can be maintained, which is beneficial to the reflux of the filtrate. When clean water is used as the filter liquid, the gas-liquid separator (8) can absorb water, reduce water loss, and reduce air humidity.

5. In the above and related embodiments, in order to ensure the normal operation of the purification box, the filtrate height measuring electrode (12) is installed on the inner wall of the purification box shell (1). The electrodes are a pair of isolated metal sheets, which are pasted on the purification box On the inner wall of the casing (1), each metal sheet is connected with an external measuring circuit through wires. When the filtrate height is lower than the electrode height, the measurement circuit will automatically send out an alarm signal to prompt people to add or replace the filtrate to ensure the air purification effect.

The above family indoor air purification devices can also be used in offices, hotels, cinemas, shopping malls, gyms, cars and train compartments and other personal and collective living and workplaces. The structure, size and manufacturing materials of the purification boxes used in these different places There will be different changes with the process, but their basic feature is to use the "pressurized upflow, liquid filtration" method to achieve air filtration and purification.

Because the utility model adopts the liquid filter type air purification technology, such as the principle of water washing, it can effectively absorb air pollutants such as smog and formaldehyde, and the degree of air pollution can be judged by changing the filter liquid, and the air purification effect is clearly visible; the purification system also has cost Low, easy maintenance, simple operation, safe and practical.

The above is a specific introduction to the embodiments of the utility model, which is used to help understand the structure and working principle of the utility model. Apparently, the described embodiments are not all of the present utility model, and all other embodiments obtained by utilizing the principle provided by the present utility model without making creative efforts all belong to the scope of protection of the present utility model. At the same time, for those skilled in the art, according to the idea of the utility model, there may be changes in specific implementation details and application scope, and the content of this specification should not be construed as limiting the utility model.
