Technical field
The invention belongs to aluminium polychloride production technical field, more particularly to a kind of production aluminium polychloride reactor.
Background technology
Aluminium polychloride (Polyaluminium Chloride) is a kind of inorganic polymer coagulant, and english abbreviation is
PAC, the molecular weight that is produced due to the polymerization of the bridging action and multivalent anions of hydroxide ion is larger, electric charge is higher
Inorganic polymer water treatment agent.Two kinds of solid and liquid can be morphologically divided into again, and solid divides by color is different
For sepia, yellow and white.
Aluminium polychloride is mainly used in water treatment field, including clean water treatment, such as domestic water, industrial water, city
Some slag recovery etc. in sewage disposal and industrial wastewater, sewage, the processing of sludge and sewage.
Because the corrosivity of its reaction is very strong in aluminium polychloride preparation process, the existing device for preparing aluminium polychloride is such as
Shown in Fig. 1, all it is to build reaction tank 1 in underground, is built into the inwall of reaction tank 1 using acid-resistant cement, and post ceramic tile, still
In the hot conditions of course of reaction, reaction tank 1 is easily caused the damage leakage of reaction tank 1, due to anti-by extremely strong corrosiveness
Pond 1 is answered to be located in the ground, it is not easy to detect the distress condition of reaction tank 1 in time, it is impossible to on-call maintenance, so that can not find in time
The leakage situation of reaction tank 1, is polluted.
The content of the invention
It is an object of the invention to provide one kind to produce aluminium polychloride reactor, it is intended to solves existing aluminium polychloride
Reaction tank under industrial land, it is not easy to detect the distress condition of reaction tank in time, it is impossible to on-call maintenance, so that can not send out in time
The leakage situation of existing reaction tank, so that the technical problem polluted.
The present invention is achieved in that a kind of production aluminium polychloride reactor, including is arranged on the kettle on ground
Body, the kettle are provided with fiberglass lid, and the kettle includes the carbon steel layer of outer layer and the frp layer of internal layer, the carbon steel
Layer outside is provided with silicon carbide layer, and ceramic tile is pasted with by tack coat on the frp layer, and the kettle is interior to be provided with agitating device,
The kettle is provided with vapor absorbing apparatus.
As an improvement the tack coat is the resin-bonded layer added with silica flour.
As a further improvement, the thickness of the frp layer is 0.8 centimetre.
As a further improvement, glass wool cloth, the glass fiber are provided between the silicon carbide layer and the carbon steel layer
Cloth is wrapped in the carbon steel layer.
As a further improvement, the kettle is provided with tilting bottom, on the kettle wall close to the autoclave body bottom most
The position of low side is provided with discharging opening.
As further improving, the angle of inclination of the autoclave body bottom is 30 degree.
As a further improvement, the vapor absorbing apparatus includes the glass reinforced plastic pipe connected with the kettle, the glass
The steam (vapor) outlet connection subordinate spray absorber of glass fastener for connection at least one-level spray absorber, wherein higher level's spray absorber
Steam inlet, each spray absorber connects the kettle by glass reinforced plastic pipe.
Due to using above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Because production aluminium polychloride reactor provided by the invention includes being arranged on the kettle on ground, convenient inspection
The damage leakage situation of kettle is surveyed, and is easy to repair, kettle includes the carbon steel layer of outer layer and the frp layer of internal layer, and institute
State and be provided with silicon carbide layer on the outside of carbon steel layer, ceramic tile is posted by tack coat on frp layer, the firm wear-resisting antiseep of kettle, energy
High temperature resistant and sour corrosion, adapt to prepare the reaction condition of aluminium polychloride, it is durable in use, substantially reduce the cost of overhaul.
Because kettle is provided with vapor absorbing apparatus, hydrogen chloride steam caused by reaction is passed through into spray-absorption, returned again
Return and reaction participated in kettle, avoid reacting caused by hydrogen chloride steam be directly discharged in air, avoid causing wastage of material and
Environmental pollution, and because the hydrogen chloride steam of reactor discharge has higher temperature, high-temp chlorination hydrogen steam is inhaled with spray
The higher aqueous acid of temperature is formed after the water mixing of receipts tower ejection, it is not necessary to is heated can and is entered the interior participation of reactor instead
Should, and the rise of aqueous acid temperature is fast, greatlys save the steam resource required for heating.
Kettle is provided with fiberglass lid, maintenance of conveniently uncapping, and fiberglass lid is corrosion-resistant, polymerize suitable for preparing
The environment of aluminium chloride.
Because the tack coat of kettle is the resin-bonded layer added with silica flour, cohesive is good, and high temperature resistant is corrosion-resistant.
Because the thickness of frp layer is 0.8 centimetre, good corrosion resistance, high-strength light, heat-insulating property is good, effectively prevents heat
Amount is scattered and disappeared, and designability is strong, and manufacturability is excellent, can be as needed, neatly designs various structural glass steel part
Meet requirement, there is good globality, can be according to the shape of product, technical requirements, purposes and quantity come neatly
Select moulding process.
Due to being provided with glass wool cloth between silicon carbide layer and carbon steel layer, glass wool cloth is wrapped in carbon steel layer, improves carbonization
Bond strength between silicon layer and carbon steel layer.
Because kettle is provided with tilting bottom, discharging opening is provided with close to the position of autoclave body bottom least significant end on kettle wall, is facilitated
Material discharge in kettle, effectively avoids material from being deposited on autoclave body bottom, when the angle of inclination of autoclave body bottom is 30 degree, discharge and
Prevent that material effect of settling is best.
Because vapor absorbing apparatus includes the glass reinforced plastic pipe connected with kettle, glass reinforced plastic pipe connection at least one-level spray-absorption
The steam inlet of the steam (vapor) outlet connection subordinate spray absorber of tower, wherein higher level's spray absorber, each spray absorber
Kettle is connected by glass reinforced plastic pipe, can the hydrogen chloride gas that contain in the steam that effectively absorbing reaction kettle is discharged, and by hydrogen chloride
Gas is recovered in reactor and utilized, and economizes on resources, and avoids hydrogen chloride gas from being discharged in air and pollutes environment and waste
Resource.
Production aluminium polychloride reactor provided by the invention, antiseepage leakproof corrosion-and high-temp-resistant, kettle is firm, prolonged
Durable, easy access, using effect is good.
