Description

Dehumidifier

The present invention relates to a dehumidifying apparatus, and in particular, a dehumidifying apparatus used to remove moisture at a beach or adjacent thereto is prevented from being corroded by salt in the air to improve durability and improve a dehumidification air conditioning efficiency. It relates to a dehumidifier equipped.

In general, the air in the beach or adjacent areas contains a lot of moisture and salinity, so factories, residential buildings, and research institutes located here are always exposed to moisture and salt, making it difficult to expect a pleasant living and working environment. In order to prevent this, the dehumidifier is used to remove moisture from the air.

In FIG. 4, the structure of the conventionally well-known dehumidifier is shown schematically.

The humid air introduced into the room from the atmosphere by the first fan 2 is absorbed by the dust removal filter 4, and the moisture is changed by the state of the refrigerant passing through the inside of the cooling / dehumidifying constant temperature means 6. Is condensed and discharged and cooled at the same time. At this time, the cooling and dehumidifying constant temperature means 6 is connected to the compressor 8 and the refrigerant receiver 10 for compressing the low pressure steam refrigerant into the high pressure steam refrigerant and between the compressor 8 and the refrigerant receiver 10. The condenser 12 is connected to the heat radiation condensation of the high-pressure steam refrigerant to the high-pressure refrigerant liquid.

The cooled air passes through the rotor 16 that is rotated by the motor 14 as a driving means, and moisture in the air that is not removed is dehumidified again and supplied into the room in a dehumidified state.

On the other hand, since the rotor 16 contains moisture by the dehumidification action, the moisture must be removed to improve the dehumidification efficiency, and thus, the rotor 16 is heated by the external air by sucking the outside air with the second fan 18. By passing through the quarter region 22 of the (16) to evaporate the moisture of the rotor 16 to increase the dehumidification efficiency.

In the conventional dehumidifying apparatus, the heater 20 is in the form of a card ridge, and if a momentary power failure occurs, the second fan 18 is not driven and the flow of air is stopped, thereby overheating the heat of the heater 20 itself. As a result, there is a risk of fire, and in a high-temperature environment in summer, as the condensation efficiency of the condenser 12 installed outside to radiate heat is reduced by 30% or more, the dehumidification efficiency is reduced accordingly, resulting in an inefficient and smooth dehumidification effect. There was a hard problem getting it.

In addition, in the conventional dehumidifier, the filter 4 for dust removal is employed, but fine dust and salts of 0.3 to 10 μm are not removed, so that not only corrosion and failure of the dehumidifier itself but also fine dust and salt are contained in the rotor 16. It is solidified and laminated after attaching to the rotor, which greatly reduces the dehumidification efficiency of the rotor and shortens its lifespan, consuming more than twice the maintenance cost, and dehumidifying the salt contained in the air flowing into the room. There was a flaw that the damage problem was not completely solved.

The present invention devised to solve such a problem with the prior art, to remove the fine dust and salt contained in the air to improve the durability with the dehumidification efficiency of the rotor, when the external environment where the condenser is disposed at a high temperature An object of the present invention is to provide a dehumidifying apparatus capable of preventing a decrease in condensation efficiency.

To this end, a salt removal filter is disposed between the dust removal filter and the cooling dehumidification constant temperature means to remove salts contained in external humid air, and the wet cooling is performed between the salt removal filter and the cooling dehumidification constant temperature means. Cooling air flowing into the means to remove the residual fine dust and residual salt contained in the air passing through the dust removal filter 34 and the salt removal filter to cool the air at the same time, the cooling means Injecting the cooling means above the upper portion of the installation, and the ceramic heater that can dissipate the instantaneous residual resistance even if the flow of external air drawn in by the second fan is stopped, replacing the conventional heater to lower the insulation resistance To prevent it.

Particularly, the condensate collecting means for collecting the condensed water condensed from the air cooled by the vaporization heat of the refrigerant in the cooling and dehumidifying constant temperature means includes a reservoir installed below the cooling and dehumidifying constant temperature means, and a discharge pipe connecting the reservoir and the injection means. And a strainer, a water purifier for removing salt and foreign substances, a pump, a throttling valve, and a flow control valve installed in the discharge pipe.

In addition, a condenser attached to the condenser and bypassed to the discharge pipe may be provided with a cooler for cooling the compressed refrigerant gas of the condenser using the condensed water discharged through the discharge pipe from the condensate collecting means.

In addition, the condensed water generated by the cooling and dehumidifying constant temperature means may be used as cooling water to remove foreign substances and salts.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing the configuration of a dehumidifying apparatus according to the present invention, Figure 2 is a block diagram showing the operation of the dehumidifier, Figure 3 is a block diagram showing a recycling process of the condensate generated in the dehumidifier.

As can be seen in the figure, the dehumidifier according to the present invention is divided into a dehumidification unit 31 for removing dust, salt and moisture contained in the air by inhaling the atmosphere, and a regeneration treatment unit 30 for improving the dehumidification efficiency. .

The dehumidifying unit 31 receives external humid air by the first fan 32, and the external humid air passes through the first dust removing filter 34 and collects and removes 10 μm or more of dust and salt particles. Next, the fine dust and salt particles that are not removed while passing through the salt removal filter 36 according to the features of the present invention are removed, and the salt removal filter 36 has a bag shape in which fibrous particles are specially processed. Bag trapping filters out fine dust and salt particles between 0.3 and 10 μm, and there is no clogging even if they are collected in large quantities.

The wet cooling means 38 installed in close proximity to the desalination filter 36 will be described later to remove the remaining salinity of the air passing through the desalination filter 36 and to cool the air as much as the summer superheat degree of the inlet air. The cooling water injected by the injection means 40 to pass through.

In particular, the cooling means 38 is a sterile, odor-resistant glass fiber synthetic inorganic material is formed in a honey-comb (honey-comb) shape as the cooling water flows down and repeats the zigzag to form a screen of the net in the air passing through Residual fine dust, organic solvent gas and salt particles are completely washed, and are first precooled by cooling water.

The injection means 40 is installed above the cooling means 38, and a plurality of nozzles are arranged so that the cooling water is evenly sprayed onto the entire upper surface of the cooling means 38.

On the other hand, the air passing through the cooling means 38 is converted to air in a cooled state while passing through the cooling and dehumidifying constant temperature means 42. At this time, the cooling and dehumidifying constant temperature means 42 is connected to the compressor 46 and the refrigerant receiver 48 connected to the condenser 44 by the return pipe 50 and the supply pipe 52, respectively, according to the state change of the refrigerant. The following freezing effect is obtained. An expansion valve 54 is provided in the supply pipe.

That is, the refrigerant passing through the inside of the cooling and dehumidifying constant temperature means 42 absorbs latent heat from the surroundings and cools the air while continuously evaporating, and the vaporized low-pressure steam refrigerant flows into the compressor 46 and is converted into high-temperature, high-pressure steam. After the condenser 44 dissipates heat to the surroundings, it becomes a high-pressure liquid refrigerant, and the refrigerant stored in the refrigerant receiver 48 is supplied to the expansion valve 54 so that the pressure drops and the refrigerant liquid of the low pressure tends to evaporate. Then it is introduced to the cooling and dehumidifying constant temperature means 42 again.

At this time, the excess moisture contained in the vaporized air by the refrigerant passing through the cooling dehumidifying constant temperature means 42 condenses to generate condensed water, and the air is switched to the cooled dry state.

The condensed water is collected by the condensate collecting means 56 to utilize the cooling water.

The condensate collecting means 56 is, for example, as shown in the drawing, a reservoir 58 installed below the cooling and dehumidifying constant temperature means 42, which links the reservoir 58 and the injection means 40. The discharge pipe 60, the strainer 62, salt and debris removal water purifier 64, the pump 66, the throttling valve 68 and the flow control valve 70 installed in the discharge pipe (60).

Here, the temperature of the condensed water stored in the reservoir 58 is enough to be used as the cooling water passing through the wet cooling means 38 described above because it is about 10 ° C., which is relatively lower than the surrounding environment.

The reservoir 58 is connected to the discharge pipe 60, the discharge pipe 60 is branched into two lines so that the first branch pipe 72 is connected to the nozzle of the injection means 40, the second branch pipe 74 ) Is connected to the cell cooler 76 attached to the condenser 44 to cool the condenser 44 to contribute to the heat radiation action of the condenser 44.

Here, the strainer 62 installed in the discharge pipe 60, the water purifier 64 for removing salt and foreign matter, the pump 66, the throttling valve 68 and the flow control valve 70 are the nozzle and the cell cooler 76. Ensure a smooth supply of coolant to the furnace.

On the other hand, the cooled dry air via the cooling and dehumidifying constant temperature means 42 passes through the 3/4 region 80 of the rotor 78 rotated by the motor to remove the moisture remaining in the air, thereby preliminary step. After the moisture is completely removed together with the dust and salt removed from the water, it enters the room.

The dust, salt and moisture that enter the room are removed to make the room pleasant to clean.

On the other hand, the outside air sucked from the outside by the second fan 82 passes through the ceramic heater 84, which is the regeneration processor 30, and the quarter region 86 of the rotor 78, the ceramic heater 84 As the outside air passing through is introduced into the rotor 78 including moisture, the outside air is evaporated and the moisture contained in the absorbent of the rotor 78 is evaporated in the dehumidification process, thereby improving the dehumidification efficiency of the rotor 78 to continuously dehumidify the action. This becomes possible.

In particular, the ceramic heater 84 is made of a ceramic material, even if the flow of air is stopped due to power outages, instantaneous residual heat is eliminated to prevent a decrease in the insulation resistance of the heater.

Looking at the operation of the dehumidifying device having such a structure step by step, first, through the step (90) that the external air is introduced by the first fan 32, in the foreign matter and salt removal step 100, the filter for removing dust ( 34) and the foreign matter and salt are removed through the salt removal filter 36, and in the cooling and moisture removal step 200, the foreign matter and salt are removed and sucked again by the cooling water sprayed from the wet cooling means 38. Pre-cooling of the air (waste heat recovery) takes place, and the air is cooled and dehumidified to an appropriate condition while passing through the cooling dehumidification constant temperature means 42.

Next, in the inflow stage 300, foreign matter and salt are removed, and the cooled and dehumidified air passes through the rotor 78, and moisture is completely removed again so that the interior is comfortable.

In this process, the cooling and moisture removal step 200, as including the condensate collection step 400, the cooling step 500 of the wet cooling means and the cooling step 600 of the cell cooler, the condensate collection step ( In 400, the condensed water generated by the cooling and dehumidifying constant temperature means 42 is collected and stored in the reservoir 58. In the cooling step 500 of the wet cooling means, the condensed water stored in the reservoir 58 is injected by the injection means 40. By spraying to the wet cooling means 38 by using, pre-cooling using the waste heat of the condensate, and also by flowing the condensate stored in the reservoir 58 to the cell cooler 76, by the waste heat of the condensate To cool.

As described above, the dehumidifier according to the present invention substantially solves the conventional problems.

In other words, by adopting the salt removal filter, the efficiency of the rotor, which is an expensive imported product, is extended by three times or more, and the inside of the device is prevented by reducing the efficiency caused by the fine dust and salt particles attached to the rotor and the corrosion of the device. By preventing corrosion, it is possible to reduce maintenance costs and reinvestment costs.

In addition, the conventional condensed water generated by the cooling and dehumidifying constant temperature means is discharged to the outside to remove, but can be used as the cooling water of the wet cooling means to remove the primary air pre-cooling and dust and salt and to circulate to the cell cooler attached to the condenser Therefore, it is possible to efficiently drive the condenser even in a state where the external temperature is greatly increased in summer, thereby improving the cooling efficiency by 30% or more.

In addition, the honeycomb-shaped cooling means completely removes and cleans residual fine dust, organic solvent gas and salt particles in the air, thereby increasing the cleanliness of the passing air and preventing corrosion by salt. will be.

On the other hand, in the ceramic heater, when the flow of air stops, the instantaneous residual heat disappears to prevent the heater's insulation resistance from dropping, and the life span of the ceramic heater is extended by three times or more, compared to the conventional heater, and the operating cost is reduced. The fire can be prevented in advance, so that the operation of the safe dehumidification and air conditioning system is possible.
