Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

As shown in fig. 1, a centrifugal water washing air purification air conditioning unit comprises a return air pipe 1, a purification chamber 2, a cooling and dehumidifying section 3, a humidifying and heating section 4, a circulating fan section 5 and an air supply pipe 6.

The outlet of the return air pipe 1 is communicated with the inlet of the purification chamber 2, as shown in fig. 2, a plurality of centrifugal purification modules 7 are installed in the purification chamber 2, the centrifugal purification modules 7 are arranged in a step shape and divide the purification chamber 2 into an upper trapezoidal chamber and a lower trapezoidal chamber, the inlet of the purification chamber 2 is arranged below the trapezoidal chambers, the outlet of the purification chamber 2 is arranged above the trapezoidal chambers, the inlet of the purification chamber 2 is arranged on the side surface of the lower trapezoidal chamber which is relatively maximum, and the outlet of the purification chamber 2 is arranged on the side surface of the upper trapezoidal chamber which is relatively maximum, so that firstly, the return air pipe introduces high-temperature air flow which is characterized by natural ascending kinetic energy, therefore, the centrifugal purification modules are adopted to divide the purification chamber 2 into the upper chamber and the lower chamber, so that the air can flow from bottom to top, and in addition, in order to meet the large air volume requirement of air conditioner return air, avoid the entry undersize, the velocity of flow is too high, causes the impact to centrifugal purification module, arranges centrifugal purification module echelonment for under the prerequisite that two upper and lower cavity volumes equal, the lateral wall area that is used for installing entry and export is enough big, also just can be big enough with the entry and export design, thereby satisfies the demand of big amount of wind.

Wherein, centrifugal purification module's major structure includes the casing, centrifugal impeller, driving motor and water throwing subassembly, the below of casing is the entry, the top is the export, dirty air gets into from the entry, external water pipe sends into water flow water throwing subassembly, water throwing subassembly throws water all around to throwing away like the water throwing dish, form water smoke, after adsorbing with the impurity in the air, form dusty water smoke, get into centrifugal impeller along with the updraft, under centrifugal force, the drop of water is thrown to the lateral wall by centrifugal impeller, can also further break into the drop of water and break into in the littleer drop of water gets into the air simultaneously, adsorb with more impurity, adopt this kind of centrifugal mode to get rid of impurity back, clean air is discharged from the top.

The air flow flowing out from the outlet of the purification chamber 2 passes through the cooling and dehumidifying section 3, the humidifying and heating section 4 and the circulating air section 5 in sequence and then enters the blast pipe 6.

Install surface cooler 8 in the cooling dehumidification section 3, reduce the temperature through surface cooler 8, too much steam condenses naturally and goes out, form the water droplet, the air is dried naturally, install its reason lie in, a large amount of water smoke has been mended in the centrifugal purification module 7, be arranged in getting rid of the impurity in the air, and the temperature of air this moment still is in the high position, lead to the very easy humidity that increases the air of water smoke, bring negative effects under constant temperature and humidity environment, consequently, increase cooling dehumidification section 3, be used for with the air drying of cooling, get rid of steam, reduce humidity.

However, the reduction of humidity is not easy to control, and the air is easily over-dried, so that a humidification heating section is connected behind the humidification heating section, a micro-mist spraying module and a heat exchanger are installed, the air temperature is improved in a heat exchange mode, meanwhile, water vapor is supplemented, the temperature is improved to the required temperature again, and meanwhile, the humidity is controlled, wherein the micro-mist spraying module 9 comprises a plurality of vertically arranged water pipes and atomizing nozzles uniformly distributed on the water pipes.

Between clean room 2 and the cooling dehumidification section 3, between cooling dehumidification section 3 and the humidification heating section 4, all install baffle 10 between humidification heating section 4 and the circulating fan section 5, set up the wind hole on the baffle 10, the below of cooling dehumidification section 3 and humidification heating section 4 sets up waste water collecting vat 11 and drain pipe, and the water droplet that will condense and go out and too much water droplet collection of humidification in-process are discharged, avoid flowing into indoorly.

The partition plate between the humidifying and heating section 4 and the cooling and dehumidifying section 3 is a heat insulation plate, so that the two are prevented from interfering with each other and causing excessive energy consumption loss.

The working process is as follows:

the circulating fan provides main power of the whole circulating air, indoor dirty air enters the purifying chamber 2 from the return air pipe 1, is purified and finished through the centrifugal purifying module 7 in the purifying chamber 2, enters the cooling and dehumidifying section 3 to be cooled and dehumidified, then enters the humidifying and heating section 4 to be heated and humidified, provides power through the circulating fan section, enters the air supply pipe, and finally returns to the indoor space, so that the purification work of air-conditioning air is realized.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
