HCN and other solution in dissolved with a small amount of low boiling point component remove.
Utility model content
The utility model aim is to provide a kind of novel ammonium sulfate decyanation tower.
The utility model specific technical solution is as follows：A kind of novel ammonium sulfate decyanation tower, including condenser cylinder, reflux
Pipe, liquid header, liquid re-distributor, stripping section filler, tower body low head, Heating medium.Wherein, condenser cylinder is arranged
At the top of equipment, condenser inner barrel is equipped with condenser heat-exchange pipes, condenser upper tube box；Liquid header is changed positioned at condenser
Below heat pipe；Liquid re-distributor is arranged below liquid header, and is set between liquid header and liquid re-distributor
Put back into flow tube, charging nozzle；Stripping section filler is arranged below liquid re-distributor；Heating medium setting stripping section filler in
Between tower body low head.
Further, stripping section filler at least uses one kind in dumped packing, structured packing, plate column form.
Further, liquid re-distributor is groove type distributor or branch pipe distributor.
Further, liquid header is ramp type collector or straw hat formula collector.
Further, tower reducer is equipped between stripping section filler and tower reactor.
Further, tower body low head is connected with tower reactor and discharges to reboiler nozzle.
Specifically, ammonium sulfate decyanation tower is by the way of Heating medium, the ammonium salt solution containing a small amount of cyanogen component, by sulphur
Tower reactor is fallen into after sour ammonium decyanation tower gas-liquid mixed phase return port charging, the heated heating agent, that is, saturated steam of kettle material directly adds
Heat returns to ammonium sulfate decyanation tower, and gas phase rises to stripping section filler, and by direct seat in the condenser of tower top, the liquid of condensation
Body flows back through return duct and returns in tower, and the liquid of condensation and the steam of rising are completed heat in stripping section filler and passed with quality
It passs, to remove away a small amount of cyanogen component in ammonium salt solution.Furthermore, it is possible to using stripping section filler and tower body low head it
Between gas-liquid mixed phase return port is set, the mode of setting tower reactor liquid outlet opening replaces Heating medium, tower below tower body low head
Reboiler heating of the kettle material through mating heat siphon type.
The utility model has the beneficial effects that：Condenser is set up directly on tower top by the utility model, and equipment is installed more
Step up to gather, saves many pipings.Material directly condensation is dropped to from condenser heat-exchange pipes in ammonium sulfate decyanation tower, meanwhile, cyanogen
Then the condensed device upper tube box of component is discharged to corresponding workshop section by top gas outlet and is handled into row buffering, whole equipment decyanation
Efficient, obtained ammonium salt aqueous solution impurity content is few.
Description of the drawings
Fig. 1 is ammonium sulfate decyanation tower structure schematic diagram in embodiment 1.
Fig. 2 is ammonium sulfate decyanation tower structure schematic diagram in embodiment 2.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
Embodiment 1
As shown in Figure 1, Heating medium, a kind of novel ammonium sulfate decyanation tower, packet is arranged in ammonium sulfate decyanation tower in the present embodiment
Include condenser cylinder 1, return duct 2, liquid header 10, liquid re-distributor 3, stripping section filler 4, tower body low head 6, heating agent
Import 14.Condenser cylinder 1 is arranged at the top of equipment, and condenser cylinder 1 is internally provided with condenser heat-exchange pipes 11, condenser upper tube
Case 12；Liquid header 10 is located at 11 lower section of condenser heat-exchange pipes, and liquid header 10 is that ramp type collector or straw hat formula are received
Storage；Liquid re-distributor 3 is arranged below liquid header 10, and liquid re-distributor 3 is groove type distributor or branch tubular type
Distributor；Return duct 2, charging nozzle 13 are set between liquid header 10 and liquid re-distributor 3；Stripping section filler 4 is arranged
In the lower section of liquid re-distributor 3, and one kind in dumped packing, structured packing, plate column form is at least used, while stripping
Tower reducer 15 can be set between section filler 4 and tower reactor；Heating medium 14 is arranged between stripping section filler 4 and tower body low head 6,
Tower body low head 6 is connected with tower reactor and discharges to reboiler nozzle 9.
Ammonium salt solution containing a small amount of cyanogen component falls into tower reactor, tower reactor after being fed by ammonium sulfate decyanation tower Heating medium 14
Heated heating agent, that is, the saturated steam of material directly heats, and returns to ammonium sulfate decyanation tower, and gas phase rises to stripping section filler 4
It sets, condenser heat-exchange pipes 11, condenser upper tube box 12 further across direct seat in tower top, then through gas outlet at the top of equipment
