Technical Field

The invention relates to the field of dehumidification devices, in particular to a marine air dehumidification device with an oil mist removing function.

Background

Electronic equipment used by ships is generally placed in a closed space, and in order to ensure good operation of some special electronic equipment, the temperature of the closed environment where the electronic equipment is located needs to be adjusted, and the humidity of air in the closed environment where the electronic equipment is located also needs to be adjusted. At present, a method for adjusting the air humidity of a closed space is to configure a dehumidifier to dehumidify the air in the closed space, so as to achieve the purpose of adjusting the air humidity of the closed environment. The working principle of the refrigeration circulation loop of the dehumidifier is shown in figure 1:

after the dehumidifier is powered on, a compressor 7 and a centrifugal fan 14 of the dehumidifier start working, low-temperature and low-pressure refrigerant gas is absorbed from an evaporator 8, compressed into high-temperature and high-pressure gas by the compressor 7, enters a condenser 11, condensed into high-temperature and high-pressure liquid, emits heat, enters the evaporator 8 after passing through a second filter 12, a capillary tube 10 and a first filter 9, absorbs air heat, is evaporated into gas, and then enters the compressor 7 through an air suction pipe, so that a refrigeration cycle is completed. The centrifugal fan 14 cools the wet air passing through the surface of the evaporator 8 through the filter screen, and since the surface temperature of the evaporator 8 is lower than the dew point temperature of the air, the water vapor of the air is condensed into water and discharged out of the dehumidifier; the dehumidified air is heated by the condenser 11 and discharged to the indoor, so that the refrigeration and dehumidification cycle is continuously carried out, and the moisture in the humid air is continuously condensed, thereby achieving the purpose of dehumidification.

When the ambient temperature is low (5-18 ℃), the surface of the evaporator 8 will be frosted due to low temperature in the running process of the dehumidifier, the microcomputer can automatically judge the state and timely send a defrosting instruction, the reversing valve of the dehumidifier is reversed, and the refrigerant of the dehumidifier follows the figure 1The flow is in the direction, the evaporator of the dehumidifier is converted into the function of a condenser, and defrosting is carried out due to heating. After defrosting is finished, the dehumidifier returns to a normal dehumidification state, and thus, the dehumidification-defrosting-dehumidification are continuously circulated, so that the normal work of the machine can be ensured under a low-temperature environment.

Electronic equipment is also arranged in an engine room of a ship, a dehumidifier is often required to be configured to adjust the humidity of air, but because a marine engine in the cabin is used, the air in the cabin contains a large amount of micro diesel oil mist particles, when the dehumidifier performs dehumidification work, the dehumidifier sucks the air to be dehumidified into the dehumidifier from an air suction port to perform dehumidification, the dehumidified air is sent out from an air supply port of the dehumidifier, the circulation is continuous, the humidity of the air is adjusted, when the dehumidifier works for a long time, the micro diesel oil mist particles in the air can be continuously adsorbed onto fins of a heat exchanger (an evaporator) at the air suction port of the dehumidifier, the blockage of a return air port of the dehumidifier can be caused by long-time oil mist adsorption, the air suction of the dehumidifier is influenced, the heat exchange of the heat exchanger is also influenced, and the dehumidification capacity of the dehumidifier is reduced until the dehumidification function is lost.

Disclosure of Invention

The invention aims to provide a marine air dehumidifying device with an oil mist removing function, and aims to solve the problem that in the prior art, a marine dehumidifier is easy to adsorb oil mist, so that the dehumidifying capacity is reduced.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the utility model provides a take marine air dehydrating unit of oil mist removal function, includes refrigerant circulation circuit, refrigerant circulation circuit includes compressor, condenser, evaporimeter, and wherein the condenser disposes centrifugal fan, still includes to surround in the outer band pulley transmission device of refrigerant circulation circuit, band pulley transmission device includes a plurality of band pulleys and winds in the transmission band of each band pulley, and wherein the transmission band is filter cloth, and band pulley transmission device wholly surrounds refrigerant circulation circuit and encloses compressor, condenser, evaporimeter in.

Furthermore, a plurality of belt wheels in the belt wheel transmission mechanism are distributed outside the refrigerant circulation loop in a rectangular shape, and therefore the filter cloth is surrounded outside the refrigerant circulation loop in a rectangular shape.

Furthermore, an oil squeezing roller is rotatably arranged at the relative position of one belt wheel of the belt wheel transmission mechanism, wherein the belt wheel is at the same side as the condenser, and the oil squeezing roller and the belt wheel clamp the filter cloth at the corresponding position together.

The oil collecting tank is connected to the lower portion of the filter cloth between the oil squeezing roller and the belt wheel corresponding to the oil squeezing roller.

When a refrigerant circulation loop in a dehumidifier works, the filter cloth in the belt wheel transmission mechanism is soft filter cloth, the filter cloth can absorb tiny oil mist particles in air entering the dehumidifier at an air inlet (an air inlet side of an evaporator) of the dehumidifier, the soft filter cloth absorbing the oil mist is driven by a belt wheel to move at an air outlet side of a condenser, hot air blown out of the condenser can heat the oil mist absorbed on the filter cloth to reduce the viscosity of oil, when the filter cloth absorbing the oil mist moves to an oil squeezing roller position, the oil squeezing roller and the belt wheel opposite to the oil squeezing roller rotate oppositely to squeeze the filter cloth absorbing the oil mist, the oil on the filter cloth is squeezed out and dripped to an oil collecting tank of the dehumidifier and finally discharged out of a dehumidifier body, and the clean filter cloth after passing through the dehumidifier rotates to the air inlet (an air inlet side of the evaporator) of the dehumidifier to continuously and repeatedly absorb tiny oil mist particles in the air entering the dehumidifier, air is degreased.

The device can well solve the problems that the dehumidification device in the ship engine room can not carry out dehumidification work for a long time and even the dehumidification function is lost because the air contains a large amount of tiny oil mist particles, has simple design structure and easy implementation, and has the following advantages:

1. the dehumidification device can work normally for a long time in a high oil mist environment.

2. This dehydrating unit can not only dehumidify the closed cabin, can also clear away the oil mist in the cabin room air, has strengthened personnel and equipment operational environment comfort level in the cabin room.
