Abstract

PURPOSE: To keep water drops from flying even with a higher air velocity by housing two filter media formed of a fiber material into a frame body so that a space part is produced between the filter media. CONSTITUTION: In an eliminator, filter media 1 and 1 formed by compressing a fiber material like a woven cloth are mounted being spaced by a frame body 2 so as to produce a space part 3 between the filter media 1 and 1. Two single eliminators each thus obtained are bound successively in two levels, upper and lower, to be set within an air conditioning equipment. During the operating of the air conditioning equipment, when a mist sprayed from a humidifier C passes through the first and second filter media 1 and 1 of the eliminators on an air flow, the filter media 1 and 1 trap moisture which is not absorbed by the air. Fine water sprayed is condensed into water drops when hitting the first filter medium 1. With the repetition of such a condensing operation, the water drops grown to a fixed size descends through the fiber of the filter media 1 and 1 by the dead load despite an air pressure and are drained outside the apparatus with a drain pipe 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eliminator for a spray type humidifier in an air conditioner.

[0002]

2. Description of the Related Art Generally, in an air conditioner, a humidifier is used to make up for a lack of humidity in the conditioned air during heating or cooling operation. In the case of a humidifier, an eliminator, which is a water drop remover, is installed to prevent the water sprayed by the spray nozzle from being scattered as water drops that are not absorbed in the air.

A conventionally known eliminator of this type is shown in FIG.
As shown in (1), it is composed of one filter medium A formed from a fibrous material and having a certain thickness, and a frame body B that protects the outer periphery of this filter medium, which was sprayed by a humidifier C and was not absorbed in the air. The water was collected by the filter material A and discharged to the outside of the air conditioner.

[0004]

2. Description of the Related Art In this eliminator, the fine water particles sprayed from the humidifier C condense into droplets when colliding with the filter medium A, and are repeatedly condensed to reach a certain size. The water droplets that have grown to the height move downwind along the fibers of the filter medium due to their own weight and wind pressure, and move to the leeward side.
The wind speed passing through a certain speed (for example, 4m / sec)
In the following cases, it does not fall off before reaching the leeward side surface of the filter medium and is not scattered. However, when the wind speed is higher than that speed, the wind pressure causes the fibers of the filter medium to travel and the filter medium A Water droplets blown up to the leeward side are scattered by wind pressure, causing the inconvenience of water wetting.The thicker the filter medium, the greater the air resistance and the stronger the pressure loss effect. There has been a problem that the wind speed cannot be increased above a certain speed in order to improve the capacity and heat exchange efficiency.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention divides a filter medium having a constant thickness into two pieces, and forms a space between the two pieces of the filter medium to improve the wind speed. The purpose of the present invention is to provide an eliminator that does not cause water droplets to scatter even when raised.

[0006]

DISCLOSURE OF THE INVENTION The eliminator according to the present invention is characterized in that two filter media formed of a fibrous material are housed in a frame so that a space is formed between the filter media. That is, it is characterized in that a filter medium having a certain thickness is divided into a first filter medium and a second filter medium, and a space is formed between the two filter mediums.

[0007]

According to the present invention, the water particles collected by the first filter medium grow into water droplets, which cannot be completely dropped in the filter medium. The growing water droplets are scattered in the space and cannot be dropped to some extent. The grown water droplets are collected by the second filter medium and fall within the filter medium before reaching the leeward side surface, and the water droplets are not scattered.

[0008]

Embodiments of the eliminator according to the present invention will be specifically described with reference to the drawings. 1 is a front view of the eliminator of the present invention, FIG. 2 is a vertical side view of the eliminator, and FIG.
[FIG. 3] is an explanatory view of the use state of the eliminator of the present invention, in which 1 is a filter medium formed by compressing a fiber material like a nonwoven fabric, and 2 is a metal or synthetic resin frame for protecting the outer periphery of the filter medium. It is a body and is the same as the outer peripheral frame 21.
Frame-shaped frames 22 and 22 surrounding both sides of and two filter media 1,
1 is composed of partition frames 23, 23 for mounting 1 at intervals so that a space 3 is formed between the filter media, and the outer periphery of the filter media is inserted between the respective frames 22, 23. The filter media 1 and 1 are attached and completed. In this embodiment, the filter material on the windward side is called the first filter material, and the filter material on the leeward side is called the second filter material. In the figure, reference numeral 25 is a drain port formed at the bottom of the groove 24 formed by the outer peripheral frame 21 and the partition frames 23, 23.

In the state of use shown in FIG. 3, two single eliminators connected in two stages, upper and lower, are installed in the air conditioner, and are sprayed from the humidifier C during operation of the air conditioner. Moisture that is not absorbed by the air when the mist passes through the first and second filter media 1 and 1 of the eliminator is collected by the filter media 1 and 1, but the sprayed fine water Is condensed into water droplets when it collides with the first filter medium 1, and the water droplets that have been condensed and have grown to a certain size descend through the fibers of the filter medium due to their own weight regardless of wind pressure, and the outer frame 21 Groove 2 formed by partition frames 23, 23
Collect in 4.

The water droplets that have not grown to a certain size are blown up to the leeward side surface by the wind pressure and are blown away from the leeward side surface toward the space portion 3. By the time it reaches the filter medium 1, it drops in the space 3 and accumulates in the groove 24 in the upper eliminator, and is connected to the drain port 25 through the drain hose 4 which passes through the space 3 in the lower eliminator. It falls into the groove 24 of the eliminator and is discharged to the outside of the machine by the drain pipe 5 together with the water collected by the lower eliminator.

Since the water droplets scattered from the leeward side surface of the first filter medium 1 and reaching the second filter medium 1 have grown to a certain size, a certain amount of water droplets or more are required before moving toward the leeward side surface. It grows to a size and is not blown up to the leeward side by wind pressure, and like the first filter medium, it descends along the fibers of the filter medium due to its own weight, accumulates in the groove 24, and is discharged to the outside of the machine.

[0012]

According to the eliminator for a spray type humidifier according to the present invention, a filter medium having a constant thickness is divided into a first filter medium and a second filter medium, and a space portion is formed between the filter mediums to form a filter medium. The space between them is insulated. Water droplets that have been collected by the first filter medium and have grown to a size that cannot be scattered are removed in the space, and water droplets that have not been able to be removed in the space are removed by the second filter medium. As a result, water droplets will not scatter even if the wind speed is increased compared to the conventional eliminator, and the air processing capacity and heat exchange efficiency can be improved by increasing the wind speed. It is a thing.

Further, since most of the water droplets that cause clogging of the filter medium are removed in the space between the filter mediums, the air resistance is reduced and the pressure loss is lower than that of the conventional eliminator using one filter medium. It is possible to reduce the load and reduce the load on the blower motor.
