As an alternative implementation mode, the condensing agent works in the heat exchange tube, and the moisture exchanges heat with the heat exchange tube through the condensing agent to obtain gas after cooling treatment; the cooled gas is transferred to the drying structure via the evaporator.
As an alternative embodiment, the cooling structure further comprises a condenser; two ends of the condenser are respectively connected with an inlet of the heat exchange tube and an outlet of the compressor; the condenser is provided with a fan which cools the condensing agent passing through the condenser.
As an alternative embodiment, the cooling structure further comprises a bypass valve; the bypass valve is arranged between the condenser and the compressor, one end of the bypass valve is connected with the inlet of the condenser and the outlet of the compressor, and the other end of the bypass valve is connected with the inlet of the heat exchange tube.
As an alternative embodiment, the cooling structure further comprises an expansion valve, wherein a valve body of the expansion valve is arranged between the condenser and the heat exchange tube, and two ends of the expansion valve are respectively connected with an outlet of the condenser and an inlet of the heat exchange tube.
As an alternative embodiment, the expansion valve further comprises a bulb; the temperature sensing bag is arranged between the outlet of the heat exchange tube and the inlet of the compressor; the temperature sensing bag is connected with the valve body to control the opening and closing of the valve body.
Specifically, the utility model obtains anhydrous dry gas by cooling and drying compressed gas with water vapor, and is used for injecting the anhydrous dry gas into an electrohydraulic preparation tank with a longer pipe orifice, so that the electrohydraulic preparation tank has air pressure difference, and preparation liquids with different components in different electrohydraulic preparation tanks flow and are mixed under the air pressure difference.
Furthermore, the precooler is arranged at the inlet of the evaporator, and can recover the cold energy carried by the compressed air cooled by the evaporator and cool the compressed air carrying a large amount of water vapor at a higher temperature by using the cold energy, so that the heat load of a refrigeration system of a cold-dry machine is reduced, and the aim of saving energy consumption is fulfilled.
The specific implementation principle of the utility model is as follows: as shown in fig. 2, the gas to be dried, carrying a large amount of water vapor, enters the precooler from the first transmission port of the precooler, sinks into the evaporator with a large amount of high-temperature moisture, and swirls on the outside of the heat exchange tube to exchange heat with the low-temperature condensing agent inside the heat exchange tube, thereby reducing the gas temperature. The cooled wet gas enters a gas-water separator, and the gas-water separator with excellent process removes 99.9% of water in the low-temperature wet gas and then is discharged through an automatic drainer. The dried gas is returned to the precooler through the fourth transmission port. The dried gas entering the precooler through the fourth transmission port is mixed with the high-temperature wet gas entering the precooler through the first transmission port, the dried gas entering the precooler through the fourth transmission port is subjected to pre-cooling for the high-temperature wet gas entering the precooler through the first transmission port, the temperature of the gas is also increased, and the gas after the temperature is increased becomes drier. Because the gas with a large amount of water vapor is heavy, the gas automatically sinks to enter the evaporator through the second transmission port. And the dried gas is lighter and leaves the precooler through the third transmission port for users to use.
The compressor below stores a large amount of condensing agent, and the condensing agent is transmitted to the bypass valve and the condenser through the outlet of the compressor. And a small part of condensing agent is conveyed to an inlet of the heat exchange tube through the bypass valve, directly enters the evaporator through the heat exchange tube, and the rest part of condensing agent is continuously conveyed to the condenser. The condensing agent passing through the condenser is cooled by a fan on the condenser for the first time, and when the condensing agent is transmitted to the expansion valve, the condensing agent is cooled for the second time. The condensing agent after the secondary cooling is mixed with the condensing agent which is transmitted to the heat exchange tube by the bypass valve and is not subjected to the secondary cooling, and then enters the heat exchange tube in the evaporator. The step is to prevent the condensing agent cooled by the second time from freezing in the pipeline of the expansion valve transmitted to the heat exchange pipe, and increase the energy consumption of the device. The mixed condensing agent enters the heat exchange tube, is cooled by high-temperature wet gas in the heat exchange tube, returns to the inlet of the compressor through the outlet of the heat exchange tube, and is ready for the next round of condensing operation.
The embodiment is a specific example only and does not suggest one such implementation of the utility model.
Embodiment two:
the second embodiment is different from the first embodiment in that: the utility model also provides equipment comprising the gas cooling and drying device. The implementation steps are shown in the first embodiment.
As shown in fig. 2, a drying tank may be further disposed at the dry gas outlet (third delivery port) of the gas cooling and drying device, and a drying agent is disposed in the drying tube, so that the gas can be further dried by the dryer.
