Description
Technical field
The present invention relates to a kind of filler, especially relate to a kind of mass transfer heat exchange grid packing for the field washings such as petrochemical industry, Coal Chemical Industry, iron and steel, dust arrester, belong to a kind of mass transfer heat exchange grid packing for cleaning dust device of gas-liquid mass transfer (contact) equipment.
Background technology
In the fields such as petrochemical industry, Coal Chemical Industry, iron and steel, in gas purification process, very high to the requirement of washing, dedusting, cooling, as desulfurizing tower, flue gas washing tower, quench tower etc., the system of process is usually messy, containing a large amount of dust or tar, require that the tower internals of tower has stronger anti-clogging.In Coal Chemical Industry, coal gas cooling and dedusting adopts hollow-spraying-tower, and cooling effect is poor, makes postorder purification work add difficulty.Conventional tower internals mainly contains tower tray and filler two kinds of forms.Herringbone baffle pan and angle steel tower tray are usually used in washing and cooling device, but only can remove most of dust, often do not reach clean-up effect.Because filling-material structure is updated, in a lot of production process, instead of traditional plate column, particularly structure and marshalling, structured packing that effectively mass transfer area is large, pressure drop is little obtained propagation and employment widely.
Chinese invention patent CN2527338 discloses a kind of grid packing, it has some parallel screens, plate there is plural perforation, have distance sink tube between every two blocks of screens, separately have the plastic tie corresponding with perforation book alternately through plate-pipe, two ends fixedly make it connect into an entirety, this invention can be used in washing, dust arrester, screen thickness is little, smooth surface, solves the problem of stifled tower.But the screen of this grid packing is all perpendicular to the vertical plate of horizontal plane; there is no bending; dust or solid particle mainly carry out washing wash away by the liquid of spray, dust or solid particle can directly pass screen and with screen collisionless, the collision clean result therefore for dust is poor.
China CN201760285 discloses a kind of Novel grating filler for dedusting, cooling, and structure comprises some screens arranged in parallel, and be provided with distance sink tube between screen, be equipped with pull bar in distance sink tube, pull bar is fixed by fastening bolt.But this screen specific area is little, can not realize gas phase and contact fully with liquid phase, clean result is poor.
The object of patent of the present invention is to solve the dedusting of filler in existing gas cleaning plant, washing, cooling effect are undesirable, and easily the problem such as blocking, proposes a kind of heat exchange grid packing for cleaning dust device.
Summary of the invention
The present invention proposes a kind of mass transfer heat exchange grid packing for cleaning dust device, and this filling-material structure is simple, and easy for installation, pressure drop is low, and flux is large, anti-stifled, and dedusting, washing, cooling effect are good.
Technical scheme of the present invention is as follows:
A kind of mass transfer heat exchange grid packing for cleaning dust device, comprise multiple corrugated sheet be arranged in parallel, each folding peak of corrugated sheet is provided with the identical perforation in multiple consistent size, direction, perforation on corrugated sheet on each folding peak is all in same level, by connecting plate through after perforation, by the fixing formation waveform filling block of some corrugated sheet series connection.
The circular arc that the shape of described perforation to be two ends be diameter is different, centre is rectangle, and the length of perforation is the ultimate range of two ends circular arc horizontal axis line, and length is greater than the width of connecting plate.
The Breadth Maximum of described perforation is the diameter of orthodrome, and the minimum widith of perforation is the diameter of small arc-shaped.
Described connecting plate is one piece of reeded rectangular slab of band, and every being provided with upper and lower two grooves on plate, the level interval of adjacent grooves is the distance of adjacent two panels corrugated sheet, and recess width is greater than the thickness of corrugated plating.
Described connecting plate horizontally through be positioned at corrugated sheet is rolled over peak perforation after again half-twist hold up, each groove of connecting plate is all blocked fixing with the large diameter circular arc end being positioned at corrugated sheet and rolling over perforation corresponding on peak; Some corrugated sheets become a waveform block after the connection of connecting plate; The two ends of waveform block respectively arrange one piece of fixed head, fixed head are provided with some holes, and corrugated sheet and fixed head become a stable waveform filling block.
Distance between described described adjacent parallel waveform plate is 30-80mm.
The thickness of described described corrugated sheet is 0.5-2mm.
Described corrugated sheet there is 2-5 smoothly to roll over peak.
The angle of described level and smooth folding peak two flanging is 90-150 °.
The width of described connecting plate is 15-25mm; The degree of depth 5-7mm of connecting plate upper groove.
A kind of mass transfer heat exchange grid packing for cleaning dust device, described filling-material structure is made up of the above-mentioned grid packing that some layers are setting up and down, the corrugated sheet placement direction of grid packing is perpendicular to packed tower cross section, and neighbouring two-layer grid packing is 90 ° of placements of staggering, and is close to mutually.
Grid packing of the present invention is using metal corrugated plate sheet as main mass transfer elements, each flanging of corrugated sheet and tower section at an angle, air-flow and the reverse flow of liquid stream in overall tower.When the gas containing dust flows through filler with certain speed, due to the inertial impaction effect of gas, dust and corrugated sheet collide and are attached to corrugated sheet on the surface.Liquid declines along filling surface by gravity simultaneously, contacts with uprising gas, shows to flow downward in membranaceous, and is constantly taken away by the dust be attached on corrugated sheet surface, realize the effect of dedusting, washing, heat exchange at waveform plate.The structure that is folded to of filler corrugated sheet improves specific area more, adds the chance that dust is captured, repeated action, substantially increases efficiency of dust collection.
On the whole, advantage of the present invention is: structure is simple, is convenient to install, and adopts connecting plate series connection and fixed head two kinds of fixed structures, strengthens the stable of filler, can not produce phenomenon of collapsing, extend service life.This grid packing adopts the structure at multiple level and smooth folding peak, and increase the specific area of filler, add the collision frequency of gas and filler, dust removing effects significantly improves.Fluid constantly washes away contact on waveform plate simultaneously, is constantly taken away by dust, and therefore filling surface there will not be the phenomenon of deposition and blocking.Between this grid packing waveform plate, distance is larger, porosity is high, thus filler resistance is little, pressure drop is low, liquid flooding gas speed ratio is higher, compare treating capacity with common fillers and can improve more than 50%, reasonable integral structure, life cycle is long, is a kind of economic, practical, effective, can be widely used in the new packing in the gas-liquid mass transfer (contact) equipments such as washing, dedusting.
