Description
Technical field
The utility model relates to gas purification, separator, particularly the device by the selective absorption Purge gas.
Background technology
Usually need carry out the operation of gas purification in the industrial process, need raw air is purified to remove moisture, carbon dioxide, hydrocarbon and other impurity wherein as air separation process.Utilizing adsorbent that the selection adsorptivity of gas with various molecule is carried out adsorption cleaning at present is one of method for gas purification of using always.As outer filling activated alumina adsorbents, the air cleaning absorber of internal layer filling 13X adsorbent of molecular sieve, when air during by the activated alumina bed wherein moisture be adsorbed and remove, during again by 13X molecular sieve bed wherein impurity such as carbon dioxide, sulfide, hydrocarbon be adsorbed and remove, discharge the air that purifies at last.Utilize the radial flow adsorber of the concentric bed of adsorbent selective absorption Purge gas in the known technology, its adsorption layer is straight tube configuration, axially radial dimension is identical up and down, absorber air flow chamber bulk up and down equates, so the drawback that produces is, the adsorbent of adsorbent bed bottom adsorbs saturated quickly, more up adsorbs saturated slowly more, the inhomogeneous and adsorbent of absorption occurs in the adsorbent bed and occur situation long-time, low adsorption efficiency in the duty cycle before the regeneration desorb; Analogue then appears during the adsorbent reactivation desorb, i.e. the very fast desorb of top adsorbent, the slow desorb of bottom, desorption and regeneration time lengthening.Its reason is, is cleaned gas and flows into from the absorber bottom, and in the axial flow chamber, air velocity has axial component and radial component, and this two speed component synthetic is the flow through velocity of adsorbent bed of gas penetration.Because air flow chamber lower gas flow is big, the upper gas flow is little, and spatial volume is constant about the air flow chamber, so the axial component and the radial component top of air velocity are little, the bottom is big, produces velocity gradient up and down, thereby makes the speed that the gas radial penetration flows through in the axial adsorption layer, top is little, and the bottom is big; Flow velocity flow difference in the different reflection unit interval, comparatively fast absorption is saturated to produce the bottom adsorbent thus, and the slow saturated rough sledding on top causes gas purification mask work efficient to reduce.
Summary of the invention
The utility model will solve the gas purification absorber, and up and down gas flow rate is inhomogeneous and reduce the problem of adsorption efficiency, adsorbent has the adsorption saturation time that is equal to about making the axial adsorption layer of absorber, to improve the absorber operating efficiency, provide a kind of Conical bed absorber of the present utility model for this reason.
For addressing the above problem, the technical solution adopted in the utility model is to lead in absorber cylindrical shell bottom air inlet pipe and escape pipe are arranged, the cylindrical shell top is provided with blow vent and filler adds inlet, its special character is that set radome fairing top, cylinder lumen bottom is provided with big its lower end of taper type grid directly little down and that filter screen is housed, footpath and is connected in radome fairing, described taper type grid has the two-layer of a radially alternate distance at least, form filling chamber between the adjacent two layers grid, form air flow chamber between outer grid and cylinder lateral wall, be provided with the center screen tube between internal layer grid and tubular axis, described filler adds inlet and is positioned at described filling chamber top.
Described taper type grid has the two-layer of a radially alternate distance at least, is meant to be provided with outer grid of taper type and internal layer grid.
Described taper type grid has the two-layer of a radially alternate distance at least, also be meant and be provided with the outer grid of taper type, middle level grid and internal layer grid, form outer filling chamber between outer grid and the middle level grid, form the internal layer filling chamber between middle level grid and the internal layer grid.
Can in the screen tube of described center, install the little big awl core body in footpath down in footpath, when the adsorbent reactivation desorb, air-flow is distributed with benefit so at least.
At least two-layer taper type grid in the described cylindrical shell, its tapering is suitable identical, to keep adsorption layer consistency of thickness up and down.
The utility model is owing to be provided with the little big two-layer at least taper type grid in footpath down in footpath in the cylindrical shell, the formation filling chamber can be filled out and put adsorbent between adjacent grid, it is filler, be used for selective absorption to gas, between big directly little down outer taper type grid in last footpath and cylinder lateral wall, form air flow chamber, make the air flow chamber upper space little, lower space is big, therefore, when being cleaned gas and flowing through air flow chamber, though to be diffused in air flow chamber lower gas flow big because of penetrating, the upper gas flow is little, and still can keep the axial component of air velocity and radial component to equate up and down, just, axial updraft amount reduces in the air flow chamber, can not cause the variation of gas flow rate, because axially the updraft amount successively decrease and the air flow chamber spatial volume successively decreases linear, gas pressure unanimity about in keeping dynamically, like this, the axial component and the radial component of gas flow rate are consistent up and down, gas penetration during by adsorption layer the direction and the size of air velocity also be consistent, make in the adsorbent bed up and down the adsorbents adsorb speed at each position and adsorbance homogeneous phase with, its adsorption saturation time is identical, thereby improved the adsorption cleaning operating efficiency, also helped the in good time recoil desorption and regeneration of adsorbent after saturated.Be provided with the utility model of the big awl core body in little footpath down, footpath in the screen tube of center, help the recoil desorption and regeneration of adsorbent; Adsorbent is when regeneration gas recoil desorb, and the distribution principle of its air velocity is similar during with absorption work, is that direction is opposite.
