Description
Technical field
The utility model relates to wastewater treatment equipment, the device of say so more specifically a kind of resin absorption wastewater treatment and steam desorption and regeneration.
Background technology
The waste water that contains organic pollutant adopts the resin absorption technology to handle, adsorb saturated resin and need desorption and regeneration, the desorbing agent of regeneration usefulness is the existing industrial application of gasiform steam, its way is import and the outlet that steam is set respectively in the upper and lower of resin absorption tower, the steam desorbing agent generally enters adsorption tower and carries out resin regeneration by resin bed from top, the desorption liquid Receiving bin is discharged and flowed into after the condensation to tail gas condenser from the resin tower bottom, the desorption liquid of collecting can realize that after diverse ways is handled the resource utilization of organic pollutant reclaims or harmlessness disposing, and the resin behind the desorption and regeneration carries out adsorption operations again.Chinese invention patent 200410014429.2 discloses a kind of resin adsorption method and has handled method, the Chinese utility model patent 200720108573.1 of industrial by-product hydrochloric acid and relate to a kind of industrial waste gas absorbing recovery device, Chinese invention patent 02805902.6 and described and a kind ofly the charcoal of the device of gac and the described device of regenerating is housed and removes the method for described volatile organic compounds from the process gas logistics that contains one or more volatile organic compoundss by application.Though these method and apparatus can well be realized absorption and desorption process, but the steam tail gas of desorption is not fully used, particularly in later stage of desorption process, the steam desorbing agent is through after adsorbent bed, only carried a spot of organic pollutant secretly, pressure, the temperature variation of steam desorbing agent are little, and this part desorbing agent usefulness is performance fully not, make that to finish the steam desorbing agent that desorption process consumes a lot, increased running cost.
Summary of the invention:
In order to improve the deficiency that present desorption apparatus exists, the utility model provides the device of a kind of resin absorption wastewater treatment and steam desorption and regeneration, this device can not only well be realized the absorption and the desorption process of resin, the steam tail gas of desorption can also be utilized once more.
The utility model realizes that the technical scheme that is adopted of utilizing once more of its steam tail gas is:
The device of a kind of resin absorption wastewater treatment and steam desorption and regeneration comprises resin tower, tail gas divider, trap, condenser and desorption liquid Receiving bin that polymeric adsorbent is housed; The quantity of resin tower is three, wherein has two towers carrying out desorption manipulation all the time, and another tower is carrying out adsorption operations.
The inlet mouth of each resin tower all is connected with the tail gas divider with the air outlet in this device, and cutting-off valve is set on the connecting pipeline.When the quality of the steam desorbing agent tail gas of a resin tower that carries out desorption manipulation has the value of utilizing once more, tail gas introduced the tail gas divider and be assigned in another resin tower that carries out desorption and regeneration carry out desorption and regeneration, realize the utilization once more of steam desorbing agent like this.Because there is heat exchange in the steam desorbing agent in system, can produce the phlegma of some amount, in pipeline and equipment, produce gas hammer phenomenon, trap is set in the bottom of tail gas divider in order to prevent this part phlegma, phlegma is entered the desorption liquid Receiving bin, make device obtain smooth running.
The beneficial effects of the utility model: the utility model provides the device of resin absorption wastewater treatment and steam desorption and regeneration, can realize the utilization once more of steam desorbing agent stably, has reduced steam desorbing agent consumption, has reduced cost for wastewater treatment.The utility model can be used for containing the resin vapor desorption and regeneration process of waste water after the polymeric adsorbent adsorption treatment of organic pollutant.The adsorption separation process that also can be used for chemical industry.
Description of drawings
Fig. 1 is the structural representation of the device of described resin absorption wastewater treatment of embodiment and steam desorption and regeneration, wherein 1. under meters, 2. resin tower, 3. tail gas divider, 4. trap, 5. condenser, 6. desorption liquid Receiving bin.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In each resin tower 2 polymeric adsorbent is housed all among Fig. 1, inlet mouth all is connected with tail gas divider 3 with the air outlet, and cutting-off valve is set on the connecting pipeline.When the A resin tower carries out adsorption operations, open the waste water terminal valve of A tower, close the waste water terminal valve of B, C tower, waste water enters the A tower through under meter 1 and finishes adsorption process.B, C tower are carrying out desorption manipulation at this moment, the steam desorbing agent enters from B tower top, discharge the bottom, when the tail gas of discharging has the value of utilizing once more, open the valve that valve that B tower bottom is connected with the tail gas divider and tail gas divider 3 are connected with C tower top, B tower tail gas introduced tail gas divider 3 and be assigned to the C tower carry out desorption and regeneration, tail gas is reused, and the tail gas of C tower flows into desorbing agent Receiving bin 6 through condenser 5 condensations.Same mode can realize when B tower or C tower at adsorption operations, two other resin tower during at desorption manipulation, the tail gas of a desorption column can be assigned to another desorption column through the tail gas divider and carry out desorption.
In the desorption process, because heat exchange is arranged, meeting produces the phlegma of some amount and accumulates in the tail gas divider in pipeline and equipment, when air-flow can produce gas hammer phenomenon through out-of-date.The utility model is provided with trap in tail gas divider bottom, in time the phlegma that produces is entered the desorption liquid Receiving bin, the smooth running of implement device.
Above process and legend have only been explained the situation that a resin tower carries out adsorption operations, can not illustrate that all adsorption systems only are made up of a resin tower, can require several resin towers of configuration to carry out adsorption operations according to absorption, but desorption column must be two in the cover system, the tail gas of a desorption column can be assigned to another desorption column through the tail gas divider and carry out desorption, realizes the utilization again of steam desorbing agent.In addition, those skilled in the art can make various changes or modifications the utility model after the content of having read the present invention's instruction, and these forms belong to the application's appended claims institute restricted portion equally.
