Abstract
The utility model discloses a solid poly aluminium chloride apparatus for producing, including reation kettle, reaction, blown down tank, filter press, filtrating storage tank, drying tank who connects gradually and the dissolving tank that links to each other with the reaction, reation kettle is equipped with hydrochloric acid entry, aluminium hydroxide entry and steam inlet, the dissolving tank is equipped with calcium aluminate entry and clear water inlet, and hydrochloric acid and aluminium hydroxide are in dissolving back calcium aluminate secondary response again through what the pressure in the reation kettle got into that reaction and dissolving tank back reaction groove carry behind the reation kettle internal reaction, getting into the blown down tank after the reaction, the blown down tank is carried to filter press through filter press pump and is filtered, and filtrating after the filtration gets into the filtrating storage tank and passes through liquid material pump and get into drying tank. Adopt the device provided by the utility model carry out solid -state poly aluminium chloride's production, the consumption of product each item descends, and carries out the multistep to tail gas and handle, realizes the zero release basically.
Description
Technical field
This utility model is related to reaction unit technical field, and in particular to a kind of solid polyaluminium chloride process units.
Background technology
Existing solid polyaluminium chloride is that aluminium hydroxide and hydrochloric acid are fed intake to enter reactor by technical recipe, with steam plus
Thermal response, by technological requirement controlling reaction temperature, pressure up to reaction end, then pressure release makes reacting kettle inner pressure be down to often
Pressure, the tail gas of discharge go vent gas treatment；But it is high in process of production to there is fault rate in existing process units, and product quality is unstable
It is fixed；Heat exchanger effectiveness is low, and product is every to consume larger, and tail gas is directly discharged to air, and production environment difference causes environment dirty simultaneously
Dye.
The content of the invention
Goal of the invention：For the deficiencies in the prior art, this utility model provides a kind of solid polyaluminium chloride process units, produces
Product consume low, and realize the process of tail gas.
Technical scheme：Solid polyaluminium chloride process units described in the utility model, including the reactor being sequentially connected, instead
Answer groove, blow tank, filter press, filtrate tank, dry slot and the dissolving tank being connected with reactive tank；The reactor is provided with
Hydrochloric acid entrance, aluminium hydroxide entrance and steam inlet, the dissolving tank are provided with calcium aluminate entrance and clear water entrance, hydrochloric acid and hydrogen-oxygen
Change after aluminum is reacted in the reactor by the pressure in reactor enter reactive tank and dissolving tank to reactive tank convey it is molten
Calcium aluminate secondary response again after solution, enters blow tank after reaction, blow tank is delivered to filter press by filter pressing pump and is filtered,
Filtrate after filtration enters dry slot into filtrate tank by liquid material pump.
Further, the reactive tank is connected with graphite cooler, and the tail gas in reactive tank is cooled down into graphite cooler
After divide two-way：Tail gas after dilute acid recycle after cooling to dilute acid bath, cooling enters film-falling absorption tower, and film-falling absorption tower is by acid
Circulating pump is circulated absorption and by the concentrated acid for absorbing discharging to concentrated acid groove.
Further, the film-falling absorption tower is connected with water scrubber and remaining hydrogen chloride tail gas is circulated with absorption, inhales
After receiving saturation, discharging is to the dilute acid bath, and water scrubber is connected with after alkali circulating slot is circulated absorption to remaining hydrogen chloride tail gas
Discharge.
Beneficial effect：Compared with prior art, advantage of the present utility model：The device provided using this utility model is carried out
The production of solid-state polyaluminium chloride, the every consumption of product decline, and carry out multi step strategy to tail gas, realize substantially zero-emission, and locate
Both the waste gas in tail gas is administered during reason, while extracting acid solution carries out secondary utilization, improves production environment, environment
It is friendly.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Structural representations of the Fig. 2 for exhaust gas processing device.
Specific embodiment
Technical solutions of the utility model are described in detail below by accompanying drawing.
Embodiment 1：Solid polyaluminium chloride process units as shown in Figure 1, including the reactor, reactive tank being sequentially connected,
Blow tank, filter press, filtrate tank, dry slot and the dissolving tank being connected with reactive tank；Reactor be provided with hydrochloric acid entrance,
Aluminium hydroxide entrance and steam inlet, dissolving tank are provided with calcium aluminate entrance and clear water entrance, and hydrochloric acid and aluminium hydroxide are in reactor
After interior reaction, after the pressure in reactor enters the dissolving that reactive tank is conveyed to reactive tank with dissolving tank, calcium aluminate is anti-again
Should, reactive tank is connected with graphite cooler, enters blow tank after reaction, and blow tank is delivered to filter press by filter pressing pump and enters
Row is filtered, and the filtrate after filtration enters dry slot into filtrate tank by liquid material pump.
As shown in Fig. 2 graphite cooler is connected with exhaust gas processing device, it is cold that the tail gas in reactive tank enters graphite cooler
But divide two-way afterwards：Tail gas after dilute acid recycle after cooling to dilute acid bath, cooling enters film-falling absorption tower, and film-falling absorption tower passes through
Acid circulating pump is circulated absorption and by the concentrated acid for absorbing discharging to concentrated acid groove.Film-falling absorption tower is connected with water scrubber to residue
Hydrogen chloride tail gas be circulated absorption, absorb after saturation discharging to dilute acid bath, water scrubber is connected with alkali circulating slot to remaining
Hydrogen chloride tail gas are discharged after being circulated absorption.
Although as described above, having represented and having described this utility model with reference to specific preferred embodiment, which must not
It is construed to the restriction to this utility model itself.In the spirit and scope of the present utility model defined without departing from claims
Under the premise of, can various changes can be made in the form and details to which.
