Technical field
The utility model is related to a kind of spray dryer, more particularly to a kind of spraying of dry chemistry catalysts to do
Dry device, belongs to catalyst equipment technical field.
Background technology
Catalyst has irreplaceable status in modern chemical industry, there are about 80% chemical reaction and catalyst
In the presence of relevant.Existing catalyst is generally nanoscale or micron-sized granular powder, Presence of an interface tension force between particle and solution,
Particle aggregation is easily produced, therefore during solution reaction prepares catalyst powder, drying is extremely critical operation.Spray
It is most common a kind of dry technology for liquid being dried to powder-product in chemical engineering industry that mist is dried, and its operation principle is：With
Material is sprayed into droplet dispersion in hot-air by the method for spraying, and material is mutual in the mode of cocurrent, adverse current or mixed flow with hot-air
It is in contact, moisture is evaporated rapidly, reaches dry purpose.Using this drying means, concentration, filtering can be saved, crushed
Destroy few Deng unit operation, and drying time short (general drying time is 5~30s), the active ingredient to dried material.
But existing spray-drying installation is during being spray-dried, often occur being adhered by dry material
Phenomenon on inner wall of tower is dried, because viscous wall material is relatively difficult to be taken out of drying tower in time, so as to cause adhesion material to burn
Or the quality of rotten influence catalyst powder；In order to improve the quality of product, the viscous wall material in drying tower is removed, it has in
Way stops drying, and it is long in turn result in the operation cycle, and production efficiency is low, continuous operation is difficult.
Utility model content
A kind of deficiency that the utility model exists for the spray-drying installation of existing catalyst, there is provided dry chemistry reaction
The centrifugal spray drier of catalyst.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：
A kind of centrifugal spray drier of dry chemistry catalysts, including material pot, spray dryer body, film
Separator and air heater, it is characterised in that heat distributor, the spraying are provided with the top of the spray dryer body
The top inner side of drier is provided with high speed centrifugal atomization device, and pneumatic vibrator is provided with the outside of the spray dryer, described
The bottom of spray dryer body is funnel shaped recovering hopper, and the bottom of the recovering hopper is provided with discharging opening, the recovering hopper
Side wall is provided with gas outlet, and the material pot is connected to the charging aperture of spray dryer body, the air heating by peristaltic pump
Device is connected by pipeline with the heat distributor of spray dryer body, the other end connection air inducing of the air heater
Machine, the gas outlet of spray dryer body recovering hopper side wall connects membrane separator by pipeline, the membrane separator it is interior
Portion is provided with dividing plate, and some membrane tubes, the one end open of the membrane tube, other end closing, the one of opening are provided with below the dividing plate
Dividing plate is inserted at end from bottom to top, and the bottom of the membrane separator is provided with discharging opening.
The beneficial effects of the utility model are：
1) high speed centrifugal atomization device that the utility model is used can carry out rotating speed according to the feed liquid solid content of dried material
Continuously adjust, to change the diameter of atomizer nozzle, so as to change the size of droplet, further reduce the possibility of the viscous wall of material
Property.Additionally, the electric high-speed centrifugal atomizer has the advantages that rotating speed high, low vibration, high stability so that material feed liquid mist
It is careful and uniform to change so that the heat exchange in drying tower is more abundant, so as to further shorten drying time and reduction
The coefficient of losses of heat energy.
2) presence of pneumatic vibrator causes constantly vibrate spray dryer in atomization process so that catalyst
Material is difficult to be attached on the inwall of spray dryer.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the inwall of the spray dryer body is provided with polytetrafluorethylecoatings coatings.
Beneficial effect using above-mentioned further scheme is so that spray dryer body has hydrophobicity, is not easy to be stained with
Addendum material and scab.
Further, the other end of the air-introduced machine is connected with air cleaner.
Beneficial effect using above-mentioned further scheme is that the presence of air cleaner can be to the sky into spray dryer
Filtration, purification is carried out before air lift, guard catalyst avoids introducing other impurity during dry.
Further, the membrane tube is made up of ceramic-metal composite material, and its external diameter is 100-150mm, and average pore size is
25-50μm。
It is the catalysis that can be good at being mingled with stop absorption air using the beneficial effect of above-mentioned further technical scheme
Agent fine particle.
