Abstract

The utility model relates to regulating filling for the reversal of a flat membrane. A plurality of internal flat bars are aligned into an array, and both ends of each flat bar are fixed on the both end wall surfaces of the filling; each flat bar forms an angle of 0 degree to 90 degrees with the vertical direction, and the inclination angles of every two adjacent flat bars, namely an upper flat bar and a lower flat bar, are reverse on the horizontal plane for facilitating the receiving of a liquid membrane flowing from the former flat bar. The structure enables the inside and the outside of the liquid membrane flowing along the flat bars to be alternately reversed to flow in an S shape. The utility model enhances the heat and mass capability and has simple structure and low price, thereby being novel high-efficiency regulating filling.

Description

Board-like inversion membrane structured packing

Technical field

The utility model relates to a kind of structured packing, particularly a kind of structured packing that is used in the industry gas-liquid heat-transfer mass transfer apparatuses such as air-conditioning, chemical industry, metallurgy, oil, environmental protection, iron and steel, pharmacy.

Background technology

At present, gas-liquid heat-transfer mass transfer apparatus such as gas cooled dehumidifying, evaporative cooling, GAS ABSORPTION, gas-liquid separation, distillation and rectifying etc. use filler that the gas-liquid contact surface is provided morely.The performance of filler is most important to the ability to work of gas-liquid heat-transfer mass transfer apparatus.The used filling kind of modern industry is various, can be divided into two big class, i.e. structured packing and graininess fillers substantially.

Structured packing be a kind of in equipment according to uniform geometric figure rule, the filler fitly piled up, this filler has been stipulated the stream of gas, liquid in the packing layer artificially, its planform and arrangement mode will influence fluid flowing and distribution and gas-liquid contact condition in bed, improve the phenomenon of channel and wall stream in the random packing, greatly reduce pressure drop, improved the effect of heat transfer, mass transfer.The structured packing kind is a lot, can be divided into screen waviness packings and mellapak packing according to its structure.Common structured packing has: metallurgic orifice corrugated packing, ceramic corrugated plating, ripple silk net with holes etc.

The granular pattern filler is meant the filler to huddle when installing, and also can put in order block, is called random packing again.The granular pattern filler can be divided into ring packing, saddle packing, saddle ring filler and other fillers according to its shape.

In the industry of chemical industry type, the built-in filler of packed tower can reach the needed contact condition of good heat transfer mass-transfer performance for making gas-liquid two-phase, need to pile up higher, and cross-sectional area is bigger, therefore, filler is mostly piled up the combination filling with bulk in the tower, produced the some shortcomings part: after piling up combination, between filler, there are a lot of gaps, the part gas-liquid flow can be passed through these gaps, making its gas-liquid flow cross gap after-purification effect reduces, and the gap that has a lot of out-of-shapes and vary in size between the packed tower inwall, cause between the filler of piling up combination in the tower not compact firm, under the effect of gas-liquid flow pressure, filler relatively moves easily or overstocks, and filler misplaces easily or damages, the part specific area that the original in addition general filler that uses is used for the gas-liquid exchange is big inadequately, makes the gas-liquid flow skewness.Reduce the heat and mass effect, and caused the tower internal resistance to raise, increased power and expended, shortened the life cycle of filler.In addition, the filler of production pattern complexity needs complicated technology, and production cost is raise.

The filler of using in the air-conditioning industry is owing to be subjected to volume restrictions, and the heat and mass transfer performance of filler is had higher requirement.In short conveying flow, need to reach export standard, make the structural shape of filler complicated more, the gas-liquid contact surface that provides is more effective and reasonable, simultaneously can not produce bigger pressure drop, and suitably reduce production costs, it is strong just to need to seek the mass transfer ability, and flow resistance is little, be easy to processing, the new packing of cheap high performance-price ratio.

Summary of the invention

The utility model is big inadequately at the part specific area of existing structured packing gas-liquid exchange, the heat and mass weak effect, the problem of complex process, a kind of board-like inversion membrane structured packing has been proposed, this compound with regular structure filler upgrades the heat and mass surface, assurance has the liquid exposure of heat and mass potentiality to give gas, keeps big heat and mass potential difference, strengthens the heat and mass effect.

The technical solution of the utility model is: a kind of board-like inversion membrane structured packing, comprise two ends filler wall and inner plate, inner several pieces plates are arranged into an array, all plate two ends are fixed on the wall of filler two ends, every plate is in vertical direction with 0～90 angle, and every two neighbouring plate angles of inclination are opposite in the horizontal direction.

Identical or the rightabout inclination of the every adjacent two vertical setting of types plates of the plate of described arrayed.Stagger on described every adjacent two vertical setting of types plate height.The plate of described arrayed divides top and the bottom, the top and the bottom cross arrangement.Open horizontal or longitudinal groove on the described every plate.On the described every plate projection or pit are arranged.Described every plate part hollow out.

The beneficial effects of the utility model are: the utility model utilizes the liquid film counter-rotating to upgrade enhancing mass transfer principle, a kind of structured packing that is made of two ends filler wall and inner plate is provided, its heat and mass ability is enhanced and is simple in structure, cheap, is a kind of new and effective structured packing.The packed tower and the air conditioner dehumidifier compact conformation that adopt this structured packing to make, the heat and mass ability is superior.
