Description

Combination compressed air freezing drier

The utility model relates to compressed air purifier, particularly the compressed air freezing type drier.

The use of pneumatic equipment is more and more extensive, and is also more and more high to the purification requirement of source of the gas.The compressed air freezing type drier can not only reach the aridity of normal pressure-23 ℃, also has the effect of oil removing, dirt, therefore purifies source of the gas with freezing dryer for compressed air and has obtained using widely.But the compressed air freezing type drier still is in the starting stage in China, no matter be that the freezing type drier of little treating capacity is (as 3Nm ³/ min) still big to 100Nm ³Before dispatching from the factory, the above freezing type drier of/min all can only do unloaded check.Even this technology relatively early Hong Kong and Taiwan area of starting also only possesses 3Nm ³The little treating capacity drying machine of/min carries out the ability that load detects.Detect and the freeze drier of high throughput is carried out load, at present economical and technically all also be unable to handle, so the production of freezing type drier leaves hidden danger, not assurance reliably on reliability.At present, the load of compressed air freezing type drier detects and all carries out in the Installation and Debugging stage in buyer factory, because the freeze drier of larger process amount can only adopt the high water-cooled refrigeration system of effect, the import rate height of its parts, structure is comparatively complicated, specification requirement to maintenance is very high, general refrigeration machine maintenance mans are not competent, therefore in case in load detection or use, break down, then need manufactory to send special technician to keep in repair, even transport manufactory's maintenance after the freeze drier that will install the dismounting back, this brings the difficulty in the maintenance to bring very burden also for makers' after-sale service not only for buyer factory.The gas output of high throughput freeze drier is that weighing apparatus is fixed, can not adjust flexibly with buyer factory day night shift gas consumption size, thereby cause waste on the energy.If the freezing type drier fault stops air feed, then can cause all fronts stopping production of buyer's station-service gas equipment and cause heavy economic losses, buyer factory have to change a huge sum of money purchase guest machine to be on the safe side, thereby increase the investment of founding the factory.

The purpose of this utility model will provide a kind of simple structure, easy to maintenance, treating capacity flexibility and changeability exactly, can make the combined compressed air freeze drier that load detects before dispatching from the factory.

Task of the present utility model is finished as follows.

A kind of combined compressed air freeze drier, it is characterized in that the compressed air drier module of several band air cooling refrigeration machines is superimposed together, the inlet of coarse gas of each freeze drier module is in charge of with thick gas inlet manifold by the band valve air inlet of each correspondence respectively and is connected airtight, and the clean gas outlet of each freeze drier module is in charge of with the purified gas house steward that gives vent to anger by giving vent to anger of each correspondence respectively and is connected airtight.

Freezing dryer for compressed air module of the present utility model can be made up of the air cooling refrigeration machine and the shell of band precooler, filter, the conduit group outer wall of described precooler is connected with fin, and the inlet of coarse gas of described precooler and the position of clean gas outlet just are staggeredly arranged.

In the drying machine module of the present utility model, filter can be by the shell with two openends, place carse, medium and small three filtering tables between described two openends to form, two openends on the described shell connect airtight with conduit group one end of precooler and the dry gas port of export of evaporimeter respectively.

The utility model has adopted little treating capacity (10Nm ³/ min is following) the air cooling refrigeration machine and the precooler of band filter form the drying machine module, this little treating capacity module has possessed the condition of loading and detecting in manufactory, so the quality of freezing type drier module is guaranteed when dispatching from the factory.Air inlet by several freezing type drier modules, band valve is in charge of, thick gas inlet manifold, give vent to anger be in charge of, purified gas is given vent to anger the compressed air freezing type drier that house steward forms, the valve in can being in charge of by each air inlet is controlled the process lot size of drying machine.Therefore the utility model has the advantage that the treating capacity of drying machine can be adjusted flexibly compared to the prior art, can adapt to the demand of the different gas consumptions of usefulness gas factory, and this is to having a great deal of practical meanings with gas factory.And close needs when repairing when one of them module hinders for some reason, remaining module still can be normally air feed continuously, can not influence the continuous production of usefulness gas factory, therefore with gas factory not needs a huge sum of money buy standby drying machine.Because the air cooling refrigeration mechanism in the module makes simply, the structure of many complexity in the water cooled refrigeration machine and supporting parts have been saved, significantly reduced the ratio of import parts, therefore the cost of whole drying machine can reduce many, moreover the air cooling refrigeration machine is very general, general refrigerator mechanic can both be competent at maintenance work, therefore brings great convenience to manufactory with gas factory.The utility model also has center of gravity low, shakes the advantage that pipeline in little, transportation and the use is not easy to crack, can reduce leakage failure.Compressed air freezing type drier of the present utility model can dispose the filter of high throughput in addition owing to all have minifilters in each module when therefore being combined into the utility model high throughput drying machine, can reduce the corollary apparatus expense greatly.

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