Description

Freezing and adsorption combined drying device

Technical Field

The utility model relates to a drying equipment field, in particular to freezing and drying device who adsorbs convolution.

Background

It is often necessary in industry to remove moisture from compressed air or process gases to achieve a certain dryness of the gas. The dryness of a gas can be expressed in terms of the water dew point. For the working condition with low requirement on dryness, the most used drying equipment is a freezing type dryer, the compressed gas is forcibly cooled by adopting the refrigeration principle, so that a large amount of water vapor and oil mist contained in the gas are cooled and condensed into liquid drops, and the liquid drops are separated by a gas-liquid separator and discharged out of the machine, thereby obtaining the dry gas.

When the pressure dew point of compressed air is required to be reduced to below 0 ℃ in application of a plurality of instruments similar to the precision electronic industry or high precision instruments, the phenomenon of pipeline icing can occur when the pressure dew point of a freezing type dryer is lower than 0 ℃. At this time, the freeze drying method cannot meet the process requirements. In which case the dew point of the adsorption dryer may be-70 deg.c. In practice, however, there are many process gases that do not require such stringent dew point requirements. Therefore, if the adsorption drying can be introduced into the freeze dryer, the defect that the dew point of the freeze dryer is not high can be compensated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a freezing drying device with adsorb convolution, mainly used solves the not high shortcoming of frozen drier dew point, introduces the absorption formula drying in frozen drier, improves drying efficiency when improving the pressure dew point.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model discloses a cooling device, including a jar body, the top of the jar body is equipped with the top cap, be equipped with the intake pipe on the top cap the jar body bottom is equipped with the fluid-discharge tube, the inside cooling chamber intermediate layer that is equipped with of shell of the jar body, simultaneously be equipped with the pipe in the middle of the internal portion of jar body cavity, the pipe is fixed in the top cap bottom, just the inside cooling chamber intermediate layer that also is equipped with of pipe wall, simultaneously the inside adsorption drying section of thick bamboo that is equipped with of pipe, the inside spiral screen pipe that is equipped with of adsorption drying section of thick bamboo, just the spiral screen pipe runs through adsorption drying section of thick bamboo top and bottom, and spiral screen pipe top is connected with the outlet duct, simultaneously the pipe is inside except.

Preferably, the air inlet pipe is obliquely arranged on the top cover. Make gaseous taking certain inclination to get into the desiccator jar internal, can increase gaseous effective collision and the improvement cooling condensation effect at jar internal.

Preferably, the bottom of the conduit is flared.

Preferably, the adsorption drying cylinder is fixed in the conduit in a spiral manner and can be detached and replaced independently. The adsorption medium is placed in the adsorption drying cylinder which can be conveniently detached, so that the adsorption medium which is adsorbed and saturated at the later stage can be replaced.

The utility model has the advantages that: the adsorption drying is introduced into the freezing type dryer, so that the pressure dew point of the drying device is improved while the drying effect is improved. Meanwhile, a plurality of drying devices can be combined for use, so that the drying efficiency is improved again, even the machine can be prevented from being stopped to replace an adsorption medium, and the automatic operation is realized.
