The present invention has two obvious characteristics that 1. a sprinkling pipe is arranged at the lower part of a washing absorption device, and the directions of sprinkling holes upward point; washing absorption liquid is upward sprinkled; the detention time of liquid drops on a washing absorption section is more two times than the downward sprinkling time of the traditional structure; upward sprinkled liquid drops impact fallen liquid drops to further increase the dispersion degree of water, to quicken the update of liquid drop surfaces, and to obviously improve washing absorption effects; 2. a large sprinkling hole with the diameter of more than 5mm is adopted to avoid the blockage of the sprinkling hole; reliability is high; large liquid drops sprinkled from the large sprinkling hole are refined by a liquid drop refining structure component arranged at the upper part for the second time and are thinner than the traditional liquid drops that are downward sprinkled; the liquid drop surface area of two-phase contact of gas and liquid is enlarged in multiples, the high efficiency of wash and absorption is ensured, and the circulation volume of washing absorption liquid is greatly reduced; therefore, the novel upper sprinkling secondary refining gas purifying technology has the advantages of high efficiency, high reliability, and obvious energy saving of washing absorption liquid pumps.
Description
Technical field
The present invention relates to a kind of spraying and secondary refinement gas purification technique of going up.It is widely applicable for the washing absorption technique of various industrial gasses and the udst separation of waste gas pollution control and treatment, also can be widely used in the udst separation of oil smoke of catering industry waste gas.
Background technology
In industrial production, the especially Chemical Manufacture, it is quite a lot of that the fountain washing gas absorbs the dust arrester number of devices.The washing absorption liquid that the spray gas scrubbing of traditional structure absorbs cleaner all sprays downwards from device top, there are three basic problems in this traditional structure: first, in order to prevent the obstruction of spray apertures, drop must not be lower than certain value from the initial velocity of spray apertures ejection, do acceleration of gravity motion with the drop that certain initial velocity sprays downwards, the washing soak time that stops in device is short, and the initial velocity that sprays is bigger, the time that stops is just shorter, and the effect that washing absorbs is just poorer; The second, the bigger washing absorption efficiency of the decentralization of washing absorption liquid is just higher, and this just requires, and spray apertures is little, drop is thin, surface area is big, little just easier obstruction the but spray apertures heals; The 3rd, in the washing absorption process, the mass transfer of the component of the component on spray droplet surface and drop inside mainly by diffusion, is restricting the raising of washing absorption efficiency downwards.
Summary of the invention
The present invention will solve traditional structure and spray the problems referred to above that the dedusting of gas scrubbing absorption plant exists downwards, a kind of spraying and secondary refinement gas purification technique of going up is proposed, make drop prolong several times in the time of staying of washing absorber portion, the gas-liquid contact area increases exponentially, and can reduce the internal circulating load of spray washing absorption liquid significantly, accelerate the drop Surface Renewal, significantly improve the washing absorption efficiency, resistance is low, and the pump operating cycle expense of washing absorption liquid is low, the reliability height, easy maintenance.
Technical scheme of the present invention is: a kind of spraying and secondary refinement gas purification technique of going up, it absorbs dedusting section, foam removal section etc. by shower, drop refined structure spare, washing and forms.Bottom or bottom that washing absorbs dust arrester are equipped with some showers of evenly arranging, and offer the spray apertures of evenly arranging on the shower, and the spray aperture all makes progress.The diameter of spray apertures is bigger, in case stop up.Spray apertures outside or above be provided with some drop refined structure spares.Drop refined structure spare is that the steel wire that overlaps is mutually formed, or the steel wire taper spring, or the several layers steel-wire screen.
The spraying and secondary refinement gas purification technique of going up of the present invention, gas is bottom-up during operation flows.The spray apertures of shower adopts the above big spray apertures of diameter 5mm, avoids spray apertures to stop up in long-term use.Though the drop of ejection is thicker, in the process that moves upward, run into drop refined structure spare and refine to carefullyyer by secondary than the drop of the downward spray of tradition, the washing sorbent surface that increases drop exponentially amasss.After upwards the liquid drop movement of spray absorbs the top of dust arrester to washing, drop is zero to begin to fall after rise motion by initial velocity under the effect of gravity again, contact washing in the process that in inverted draft, falls once more with gas and absorb dedusting, and refinement takes place, quicken the Surface Renewal of drop with the drop bump of last spray, improve purification efficiency.Calculating shows, compare with the drop that sprays downwards from the top of traditional structure, upwards the drop of spray was significantly improved in the washing effective time of staying of absorber portion from the bottom, the contact area that this just is equivalent to improve exponentially sprinkle density and gas-liquid two-phase greatly reduces the power consumption that washs the absorption liquid circulating pump.The drop of a small amount of fine mist is removed by the foam removal filler through the foam removal section time, and the process gas that washing absorbs after the dedusting leaves the washing absorption plant by outlet.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3.
1 gas access section, 2 showers, 3 spray apertures, 4 drop refined structure spares, 5 screen clothes, 6 washings among the figure absorb 11 washings of dust arrester 7 washing absorption dedusting sections 8 foam removal sections 9 refinement steel wires 10 steel wire circular cone refinement springs and absorb dedusting section top
The spraying and secondary refinement gas purification technique of going up of the present invention, during operation, gas enters gas access section 1 back and upwards flows, and absorbs dedusting section 7 through washing.The bottom that absorbs dust arrester in washing is equipped with some showers of evenly arranging 2, offers the spray apertures 3 of evenly arranging on the shower 2, and the mouth of spray apertures 3 all makes progress.Spray apertures 3 adopts the above macroporous structure of diameter 5mm, avoids spray apertures 3 may stop up in long-term use.Drop by large diameter spray apertures 3 ejections is thicker, runs into drop refined structure spare 4 after the ejection by further refinement in the process that moves upward, and absorbs the dedusting surface area with this washing that increases drop greatly.Drop refined structure spare 4 can be that the refinement steel wire 9 of the mutual overlapping shown in the accompanying drawing 2 is formed, or the steel wire circular cone refinement spring 10 shown in the accompanying drawing 3, or several layers steel-wire screen 11.
After liquid drop movement absorbed the top of dedusting section 7 to washing, drop under the effect of gravity, was that zero the beginning fallen after rise by initial velocity again.In inverted draft, contact washing in the dropping process once more with process gas and absorb dedusting, and refinement takes place, quicken the Surface Renewal of drop, the raising purification efficiency with the drop bump that upwards sprays motion.Compare with the drop that sprays downwards from the top of traditional structure, the drop that upwards sprays from the bottom, not only refine to thinner than the drop of the downward spray of tradition by secondary, the washing sorbent surface that has increased drop exponentially is long-pending, and calculate and to show in the washing effective time of staying of absorber portion and significantly improved, the contact area that this just is equivalent to improve exponentially sprinkle density and gas-liquid two-phase greatly reduces the power consumption that washs the absorption liquid circulating pump.The drop of a small amount of fine mist is separated through foam removal section 8 time to be used as washing down and to absorb dedusting liquid and reuse, and gas upwards or discharge.
