Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, the utility model reverse-flow type bromine gas absorption tower embodiment being done describe clearly and completely further below with reference to accompanying drawings.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
As accompanying drawing 1, shown in 2, reverse-flow type bromine gas absorption tower comprises tower body 1, be located at the tank body 2 of tower body 1 bottom, tower body 1 is connected with tank body 2, described tank body 2 is provided with the input pipe 3 for inputting bromine gas and the efferent duct 4 for discharging bromine solutions, by input pipe 3, a certain amount of methanol aqueous solution is input to tank body 2 inside, again bromine gas being passed into tank body 2 inside by input pipe 3 makes bromine gas be dissolved in the methanol aqueous solution of tank body 2 inside, described efferent duct 4 is provided with return duct 5, one end of return duct 5 passes into tower body 1 inside, described efferent duct 4 is provided with the first valve 6, return duct 5 is provided with the second valve 7, the junction of described efferent duct 4 and return duct 5 is provided with the drawing liquid pump 10 for twitching bromine solutions, return duct 5 is again back in tank body 2 for the bromine solutions that the concentration that exported by efferent duct 4 is not up to standard and mixes, drawing liquid pump 10 provides power to the flowing of liquid in efferent duct 4 and return duct 5, in the present embodiment, return duct 5 is between drawing liquid pump 10 exit and the first valve 6, the form of liquid output and backflow is as follows: during backflow, close the first valve 6 on efferent duct 4, open the second valve 7 on return duct 5, liquid is back in tank body 2 from return duct 5, during output liquid, open the first valve 6 on efferent duct 4, close the second valve 7 on return duct 5, liquid outputs to next station from efferent duct 4.The efferent duct 4 being simultaneously positioned at drawing liquid pump 10 porch is provided with the filter plate 11 for preventing drawing liquid pump 10 from blocking, for the sediment tube 12 of collecting precipitation thing, described filter plate 11 is between sediment tube 12 and drawing liquid pump 10 entrance, described sediment tube 12 is provided with for discharging sedimentary 3rd valve 8, filter plate 11 is arranged on drawing liquid pump 10 porch and can effectively prevents from sediment from entering in drawing liquid pump 10 causing drawing liquid pump 10 to damage, due to filter plate 11, sediment can be piled up by place, sediment is piled up for a long time and is easily caused drawing liquid pump 10 entrance to block, therefore efferent duct 4 before filter plate 11 connects a sediment tube 12, sediment Direct precipitation can not be blocked in the entrance of drawing liquid pump 10 in sediment tube 12, can effectively prevent drawing liquid pump 10 from damaging because of blocking, simultaneously can not timing sediment be discharged by the 3rd valve 8, prevent precipitate bulk too much, efferent duct 4 is also provided with the 4th valve 13, before 4th valve 13 is located at sediment tube 12, when needing to discharge sediment tube 12 sediment, bromine solutions after closing the 4th valve 13 in tank body 2 would not flow into efferent duct 4, now can open the 3rd valve 8 waste discharge thing smoothly.
The translucent polyvinylidene fluoride material of described sediment tube 12 is made, polyvinylidene fluoride is not only trnaslucent materials and has good resistance to bromine corrosive nature, the sediment state in sediment tube 12 can be observed by translucent sediment tube 12 at any time, valve can be opened when sediment arrives a certain amount of and discharge.
Described drawing liquid pump is magnetic drive pump, magnetic drive pump is formed primarily of pump head, magnetic driver, motor, can for the magnetic drive pump described in patent No. CN203394770U, when motor drives outer magnet rotor to rotate, magnetic field energy penetrates air-gap and namagnetic substance, in drive is connected with impeller, magnet rotor makes synchronous rotary, realize the contactless synchronous transmission of power, the movable sealing structure easily revealed is converted into the static seal structure of zero leakage, because pump shaft, interior magnet rotor are completely closed by the pump housing, separation sleeve, thus thoroughly solve leakage, emit the problems such as liquid.
As accompanying drawing 3, shown in 4, one end that return duct 5 passes into tower body 1 is provided with spray head 9, concentration bromine solutions not up to standard flows on tower body 1 by return duct 5, usual bromine gas is understood some and is risen, mix more fully to allow the solution of backflow and the bromine gas of rising, adopt spray head 9, make backflow solution spraying and under, effectively increase the contact area of reflux solution and bromine gas, bromine gas is better dissolved in reflux solution, the material of described efferent duct 4 and return duct 5 is polyvinylidene fluoride, polyvinylidene fluoride has very strong impact resistance simultaneously, heat-resisting quantity is strong, be suitable as circulating line to use, increase the service life of pipeline, meanwhile, the color of bromine solutions can be observed by translucent efferent duct 4, by comparison color can judge bromine gas be dissolved in methanol-water easily in state, control bromine solutions concentration, this structure overcomes traditionally by means of only controlling the proportioning of bromine gas and methanol aqueous solution to control bromine liquid concentration, its concentration controls inaccurate problem, avoid simultaneously and offer the problem that visor affects tank body 2 sealing and tank body 2 intensity on tank body 2.
The above is only exemplary embodiment of the present utility model, but not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
