Description

High-efficient dehydrator

Technical Field

The invention belongs to the technical field of dewatering separation, and particularly relates to a high-efficiency dewatering device.

Background

The compressed air is the second most powerful energy next to electricity and is a multi-purpose process air source, and compared with other energy sources, the compressed air has the advantages of being clear and transparent, convenient to convey, free of special harmful performance, capable of working in many adverse environments and the like. The compressed air is not ideal to carry a large amount of liquid water drops, which is the root cause of the corrosion of equipment, pipelines and valves, and the freezing in winter can block small-hole channels in a pneumatic system, so that a gas-water separation device is needed in the compressed air system to process the compressed air into dry air with certain relative humidity.

The common gas-water separation device on the market at present is provided with a cyclone separator and a filtering separator, but the cyclone separator and the filtering separator do not have the capacity of drying gaseous water. The cyclone separator is characterized in that liquid drops with larger inertial centrifugal force are thrown to an outer wall surface to be separated by virtue of rotary motion caused by tangential introduction of airflow, but the separator has a better separation effect on the liquid drops and water only at a certain load design point through the centrifugal force, the air consumption of a client is generally unstable, and the gas-water centrifugal separation effect is poorer if the deviation is larger; although the filtering separator can polymerize macromolecular particle state water into liquid drop state water and settle in the water collecting tank, large liquid drops with large mass can be separated along with gravity because the flow velocity of compressed air is large and the direction of air flow is inconsistent with the direction of gravity, and other tiny polymerized state water inevitably enters an air using pipeline along with the air flow, so that the air-water separation effect is still not ideal.

Referring to fig. 1, the present invention provides a technical solution: a high efficiency water trap comprising:

a dehydrator body 10, a filtering wire net 50 and an outlet pipe 21, wherein,

the water remover body 10 is provided with a longitudinally extending accommodating cavity, the middle section of the accommodating cavity is provided with a plurality of thin tubes 40 which extend vertically, circulating cooling liquid is arranged in the accommodating cavity in which the thin tubes 40 are arranged, specifically, two ends of each thin tube 40 are integrally fixed in the water remover body 10 through a flower plate 41, air to be dehydrated enters the thin tubes 40 from top to bottom after entering the accommodating cavity, and at the moment, the air to be dehydrated is rapidly cooled due to the beam action of the thin tubes 40, so that the absolute moisture content of the air to be dehydrated is reduced;

the filtering wire mesh 50 is arranged at the pipe orifice at the lower end of the thin pipe 40, specifically, the filtering wire mesh 50 is a stainless steel wire mesh, the filtering precision is 50 μm, and the filtering wire mesh is used for gathering a large amount of macromolecular particle liquid water condensed under the action of the beam current of the thin pipe 40 to enable the macromolecular particle liquid water to be a continuous water flow in a large liquid drop state;

According to the technical scheme provided by the invention, air to be dehydrated enters the accommodating cavity from the upper end of the dehydrator body 10, and then is integrated and fixed in the dehydrator body 10 through the flower plate 41 to form the thin tube 40 beam flow so as to rapidly cool the compressed air, so that the absolute moisture content of the air to be dehydrated is reduced, a large amount of macromolecular particle liquid water is condensed, and the gravity direction of the condensed water is consistent with the air flow direction in the process; the macromolecular particle liquid water is further gathered into continuous water flow in a large liquid drop state through the filtering silk screen 50 with the filtering precision of 50 mu m at the pipe orifice at the lower end of the thin pipe 40 and enters the water collecting cap 60 at the lower end of the water remover body 10, then the condensed water is discharged gradually, the gas and the water are fully separated, and the dehydrated air is led out to a subsequent gas using point through the gas outlet pipe.
