Description

Drier module for combination compressed air freezing drier

The utility model relates to compressed air purifier, particularly combined compressed air freeze drier drying machine module.

The inventor " the combined compressed air freeze drier " of separate case application be a kind for the treatment of capacity variable, be suitable for being combined into the compressed air freezing type drier of high throughput especially.Need adopt several simple structures during its combination, easy to maintenance, the compressed air good purification can be made load and detect before the product export, be suitable for being combined into the freezing dryer for compressed air module of various treating capacities, particularly high throughput.

The purpose of this utility model is exactly that a kind of drying machine module that combinations thereof formula freezing dryer for compressed air is used that is suitable for will be provided.

Task of the present utility model is finished as follows.

A kind of combined compressed air freeze drier drying machine module, have shell, air cooling refrigeration machine, its characteristics are that the inlet of coarse gas and the dried compressed air outlet outer end of the evaporimeter of described air cooling refrigeration machine are tightly locked with the precooler of being with filter, described precooler inner catheter group outer wall is connected with fin, and the position of the inlet of coarse gas of described precooler and purification of compressed air outlet just is staggeredly arranged.

The filter of the utility model freezing dryer for compressed air module can and be provided with the filtering table group that forms at interval by some filtering tables by shell and be formed, two openends of described shell connect airtight with precooler conduit group's end, the end of evaporator dry compressed air outlet respectively, and described filtering table group is between two openends of shell.

The filtering table group of the utility model freezing dryer for compressed air module can be made up of carse, medium and small three filtering tables, separate with the dish space collar between each filtering table, and the ring flange that the filtering table group is fixed on shell one end is covered with filtering table supporting spring, attachment screw.

The utility model freezing dryer for compressed air module is owing to adopt the air cooling refrigeration machine, the precooler of band filter, the heat exchange catheter group of precooler is provided with fin outward, thick gas inlet just is staggeredly arranged with clean gas outlet, has independently shell, therefore drying machine module of the present utility model both can be used as complete little treating capacity freezing dryer for compressed air separately, can be used to be combined into the combined compressed air freeze drier of multiple different disposal amount again easily.Adopt the air cooling refrigeration machine that the import rate of parts is reduced greatly, so cost is low, the specification requirement of maintenance also reduces, and common refrigeration machine maintenance mans can be competent at.Because simple structure, treating capacity is little, so possessed the condition that the previous crops load that dispatches from the factory detects, the quality of product is reliably guaranteed, make the buyer feel relieved, manufactory has also reduced many troubles of after-sale service, when becoming the compressed air freezing type drier of high throughput by the utility model drying machine module combinations, possessed the condition that the previous crops load that dispatches from the factory detects too, having changed fully can not load before existing high throughput freezing dryer for compressed air dispatches from the factory detects the hidden danger of quality of being left over, increased the transparency of quality, drying machine of the present utility model is because the heat-exchange capacity of precooler is good especially, therefore bear the very capable of excess load running, when a certain module failure is out of service in the combination type drying machines, its workload can be shared by other module, can not influence the continuous air feed of whole drying machine, not only make the combined compressed air freeze drier in the treating capacity combination, very big flexibility be arranged, using, also have very big convenience in the maintenance process, this uses factory all to have very big realistic meaning to the manufactory and the buyer.The aridity of the utility model freezing dryer for compressed air module can reach atmospheric dew point-23 ℃, the about 2g/m of water capacity ³, oil removal rate is 99.9%, therefore dust-laden particle diameter≤0.1um can satisfy the purification requirement of most industrial sources of the gas fully.

Below with reference to accompanying drawing structure of the present utility model is described in further detail.
