Description
Technical field
This utility model relates to recovery and the cleaning equipment field of industrial waste gas, particularly relates to a kind of Multi-grade exhaust gas and absorbs thickening-purification technology device.
Background technology
Producing large quantity of exhaust gas in chemical industry or industrial processes, these waste gas need through post processing, remove the harmful substance in removing exhaust gas, and then just can be discharged in air；The mode using corresponding liquid to absorb is one of conventional operational means of exhaust-gas treatment, typically uses to be passed through in liquid medium waste gas and processes；Or waste gas is processed by the mode using liquid spray.
In spray operating process, waste gas directly contacts with spray water mist, absorb the harmful substance in waste gas, but owing to the liquid of spray is in atmosphere by action of gravity, its liquid hurtles down to the bottom of spray column, and liquid fails to be fully contacted with the harmful substance in gas, and liquid medium utilization rate is the highest, exhaust-gas treatment cost is high, because there is these problems.
Therefore the process waste gas in the way of liquid medium circulated sprinkling is occurred in that, but the liquid medium recycled due to itself, in single spray operating process, liquid can not concentrate for gas, waste liquid after absorption operation is same concentration, when it is circulated spray, although certain concentration can be carried out, but when its concentration is excessive, itself absorption efficiency is substantially reduced, and after its absorbtivity is saturated, then can not absorb the harmful substance in waste gas, the harmful substance in waste gas can be caused to absorb insufficient, reaction affects the treatment effect of waste gas.
And for different types of waste gas, need to use different liquid mediums and spray equipment to absorb, single spray-absorption structure is difficult to meet the demand of its actual production.
Summary of the invention
For the problem of above-mentioned existence, this utility model purpose is to provide a kind of diverse in function, and waste gas absorption is effective, and liquid medium can make full use of, and the Multi-grade exhaust gas of flexible can absorb thickening-purification technology device according to the actual requirements.
nullIn order to achieve the above object，The technical solution adopted in the utility model is as follows: a kind of Multi-grade exhaust gas absorbs thickening-purification technology device，Described purifier is the housing sealed，Housing bottom is provided with waste gas inlet，Case top is provided with offgas outlet，The lower section of housing inner exhaust gas outlet is provided with except fog-zone，In housing, waste gas inlet is arranged over Perforated plate distributor，Except being provided with outer circulation district and inner circulation zone in housing between fog-zone and Perforated plate distributor from top to bottom，Secondary cycles district it is provided with between inner circulation zone and outer circulation district，The bottom of housing is provided with outer circulation tank、Interior circulating tank and secondary cycles tank，Described inner circulation zone、The top in secondary cycles district and outer circulation district is equipped with spray pipeline，The bottom in described secondary cycles district and outer circulation district is equipped with liquid collecting plate，Outer circulation tank is provided with new liquid import，Described outer circulation tank、Secondary cycles tank and interior circulating tank are provided with tube for transfusion and are connected to outer circulation district、On the spray pipeline of secondary cycles district and inner circulation zone，The bottom of outer circulation district liquid collecting plate is connected on the water inlet of secondary cycles tank by reflux pipe，The bottom of secondary cycles district liquid collecting plate is connected on the water inlet of interior circulating tank by reflux pipe.
As a kind of improvement of the present utility model, when being not provided with secondary cycles tank and secondary cycles district in described housing, the reflux pipe below outer circulation district liquid collecting plate is connected directly between on the water inlet of interior circulating tank；When this device is applied to the high liquid medium of absorption efficiency with waste gas, it is only necessary to two-stage spray-absorption structure can complete the absorption of waste gas and process work, it is not necessary to unnecessary secondary cycles district and secondary cycles tank, the production carrying out reduction device with this and use cost.
As a kind of improvement of the present utility model, when being provided with multiple secondary cycles tank and secondary cycles district in described housing, adjacent Liang Ge secondary cycles district, the reflux pipe in secondary cycles district, top is connected on the water inlet of the corresponding secondary cycles tank in secondary cycles district below；When this device is applied to the low liquid medium of absorption efficiency and waste gas, needing to add multistage spray equipment, the concentration of the liquid medium of multi-stage spray is inversely proportional to its setting height(from bottom), it is ensured that the evolution effect of final waste gas.
As a kind of improvement of the present utility model, described interior circulating tank is directly connected with inner circulation zone, and the bottom of described interior circulating tank is provided with sewage draining exit；Inner circulation zone is the first order reaction zone of gas, is the afterbody reaction zone of liquid medium simultaneously, has maximally utilized liquid medium, it is ensured that it can fully absorb, and then discharges waste liquid by sewage draining exit.
As a kind of improvement of the present utility model, the lower section of the spray pipeline in described inner circulation zone, secondary cycles district and outer circulation district is equipped with assist absorption filler；By assist absorption filler, the harmful substance in waste gas is absorbed, also increase waste gas and the contact area of liquid and time of contact simultaneously.
Device of the present utility model coordinates the absorbent of correspondence simultaneously, various waste gas can be carried out efficient absorption purification；If desired, can circulating tank, interior circulating tank and secondary cycles tank subpackage different component absorbing liquid outside, it is achieved a tower purifies complex component waste gas.
The utility model has the advantage of: this utility model, according to the process requirement of waste gas in actual production, selects different liquid mediums and different apparatus structures to process, the flexible structure of device own, convenient selection and regulation；During spray column absorbs, waste gas is processed by the mode using multiple stage circulation spray, the absorbance of waste gas is high, and by multistage absorption, and correspondence is more the thinnest toward upper strata waste gas component, the absorbing liquid used is the newest, strengthening assimilation effect, and purifying waste gas simultaneously, be conducive to reclaiming waste gas useful constituent by concentrating, liquid medium utilization rate is high, reduces the exhaust-gas treatment cost of enterprise.
