Description
Technical field
The utility model relates to the technical field of vacuum dryer, a kind of vacuum dryer that can recycle of containing more water smoke or steam in vacuum system material handling of being widely used in specifically, especially for some dry vacuum pumps, for example screw-type vacuum pump, Roots vaccum pump, rotary-vane vaccum pump, slide valve pump and scroll vacuum pump play dehydration when processing sour corrosion gas and have the processing medium of more steam, thereby more effectively avoid corrosion and the emulsification of lubricating oils of vavuum pump, and gas clean-up.Be particularly related to the mechanical connecting structure of its vacuum desiccator.
Background technology
Documents, application number: CN201210138962.4, the applying date: 2012.05.04, patentee: Zhejiang Chengxin Pharm&Chem Euipment Co.,Ltd, this case discloses a kind of " vacuum drier ", it comprises frame, that can rotate is located in frame and the tank body of material to be dried is housed, be sheathed on the chuck in tank body outside, be located at the filter in tank body, and the vacuum-pumping tube being connected with filter and outside air-extractor respectively, between described chuck and the lateral surface of tank body, be formed with the heat tunnel of annular and logical heat medium, it is characterized in that, described vacuum drier also comprises the blow-back pipe that is connected with filter and leads to inert gas.
Along with the development of dry vacuum equipment, in the vacuum application of chemical industry, pharmaceutical field, more and more adopt dry vacuum equipment to substitute liquid rotary pump and form vacuum application system.This be because dry vacuum equipment be utilize the gap of impeller or screw rod control backflowing of air-flow realize vacuum and and capacity realize the compression of gas.And liquid rotary pump is to adopt water ring to seal and Compressed Gas, so dry vacuum pump is compared liquid rotary pump, to have energy consumption low, the huge advantage of non-secondary pollution.
But dry vacuum pump utilizes clearance control vacuum, very high to the finishing requirements of parts, need to select the material of thermal stress minimum simultaneously, can not select stainless steel as component materials, so dry vacuum pump is being processed sour gas or is being contained water smoke and during the material of steam, cannot avoid being corroded, cause service life of equipment to shorten.Although existing a lot of producer carries out coating in metal surface, play one deck protective effect.But the plating process of high technology content is expensive owing to adopting, and the major hidden danger that still exists coating to come off, thereby cause the breaking-up of pumping equipment.And adopt common plating process, not only do not have the effect of protection, and can aggravate the corrosion rate of equipment.
Existing corrosion mainly be take the corrosion of electrochemistry intermediate ion as main, that is to say for most corrosive gas cast iron corrosion of metal is had to a necessary condition, the water that needs exactly free state, the water that makes sour gas be dissolved in free state is attached in metallic walls, thereby electrochemical corrosion phenomenon occurs.So the water of the free states such as reduction or Transformatin water mist of gas, steam is to solve the most effective that most of sour gas corrodes vacuum equipment, is also safest means.
Remove the water of the free states such as water smoke, steam for some vavuum pumps, be especially the non-water of free state of can avoiding without oily sliding vane rotary pump and slide valve pump to emulsification of lubricating oils, further gas clean-up.
On market, existing drying equipment mainly contains two kinds of chemisorbed and physical absorptions, chemisorbed is not suitable for for the vacuum application of chemical industry, pharmaceutical industry very much, thereby be difficult to determine that whether the gas of this treatment media jeopardize the safety of device or system with chemosorbent generation chemical reaction.Adopt physical absorption to exist when adsorbent is saturated, must change adsorbent and could continue to guarantee vacuum system safe operation.A kind of physical absorption Minton dryer that can recycle of utility model is guaranteeing that dry vacuum device is very urgent and important at chemical industry, pharmaceutical industry safe and reliable operation.
Utility model content
The purpose of this utility model is to provide a kind of New Cycle vacuum desiccator, it adopts and can be placed in chuck drying by independent dismountable drier wire chamber, in normal sorption process, reduce the water smoke for the treatment of media gas and the free state water of steam, in desorption process, under vacuum environment, utilize Steam Heating drying chamber to make adsorbent dehydration, thereby realize drying chamber, can recycle.
To achieve these goals, the technical solution of the utility model is: a kind of New Cycle vacuum desiccator, it comprises vacuum drying cylinder, it is characterized in that: in described vacuum drying cylinder, be provided with inside and outside double-layer vacuum drier wire netting, this vacuum drying agent wire netting is cylindric, the vacuum drying agent wire netting of ectonexine is socket shape, the barrel punishment of vacuum drying agent wire netting is furnished with some vacuum drying agent wire netting rinforcement bars, vacuum drying cylinder inwall place forms vacuum drying cylinder steam jacket, vacuum drying cylinder steam jacket outer wall is close to outer field vacuum drying agent wire netting, between ectonexine vacuum drying agent wire netting, form drier and fill chamber, one end of vacuum drying cylinder is provided with vacuum desiccator flange, vacuum drying agent wire netting one end is provided with vacuum drying agent wire netting gland, vacuum desiccator flange is provided with vacuum suction inlet, the vacuum drying cylinder other end is provided with vacuum outlet, the outer wall place of vacuum drying cylinder is respectively equipped with steam inlet and steam condensate outlet, steam inlet and steam condensate outlet all with vacuum drying cylinder steam jacket UNICOM.
The utility model discloses a kind of New Cycle vacuum desiccator, equipment is comprised of parts such as vacuum drying cylinder, vacuum drying flange, vacuum drying agent wire netting, vacuum drying agent wire netting rinforcement bar, vacuum drying agent wire netting gland, vacuum drying flange sealing ring and corresponding bolt and pads.Wherein vacuum drying agent wire netting and vacuum drying agent wire netting rinforcement bar have formed an independently drier chamber, fill the drier of the physical absorption of special stable performance, because this drier chamber is independently, when changing drier, do not need to remove vacuum drying cylinder and be connected with the pipeline between vacuum system, avoid repeating to install the hidden danger of the vacuum system leakage that may cause.Vacuum drying agent wire netting has the rinforcement bar of six vacuum drying agent wire nettings, and the hot strength of not only having reinforced wire netting has also guaranteed circular state simultaneously, makes being more evenly distributed of air-flow and adsorbent.The front and back section of rinforcement bar has projection, can be fixed on very easily in vacuum drying cylinder and vacuum drying wire netting gland, has avoided rocking under entraining air stream turbulence.
The art of this patent is different from prior art and is, the drying chamber that may have on market only plays adsorbent and fills, the effect of absorption water smoke and steam, do not possess the desorb dehydration after saturated to adsorbent, do not possess independently drier and fill chamber, can realize the excellent function of convenient disassembly simultaneously yet.
