Abstract
The utility model relates to a drying-spraying system for a catalytic cracking catalyst, comprising a spraying tower, wherein a hot-air distributor is installed at the top of the spraying tower; a spraying gun, a first-stage cyclone separator and a second-stage cyclone separator are arranged at an upper part in the inner cavity of the spraying tower; the discharge port of the first-stage cyclone separator is connected with a pneumatic butterfly valve, and the discharge port of the second-stage cyclone separator is sequentially connected with a manual butterfly valve and a material-receiving barrel; and the drying-spraying system is characterized in that the heights of the discharge port of the first-stage cyclone separator and the discharge port of the second-stage cyclone separator are greater than the height of a conical material-receiving hopper on the lower part of the spraying tower, and the discharge port of the first-stage cyclone separator is connected with the bottom of the conical material-receiving hopper on the lower part of the spraying tower via a pipeline. The drying-spraying system has the beneficial effects that a high-pressure fan can be omitted during the process flow, so that electric charge can be saved by tens of thousands of yuan for units each year; and moreover, floor space can be saved.
Description
Technical field
The utility model belongs to oil-refining chemical catalyst preparation field, relates in particular to the dry spraying system of a kind of catalytic cracking catalyst.
Background technology
The Catalyst Production unit is divided into raw material and becomes the unit such as glue, spray shaping, roasting, washing, filtration, pneumatic conveying drying, rewinding.See accompanying drawing 2 for details, the spray-dired process of catalytic cracking catalyst is that the slurries that will mix are sprayed in the spray tower, then carries out drying under EAT is 500-600 ℃ hot air source, and dried powder product carries out classification and reclaims.Roughly technique is, by the slurries that become the glue unit to come through high-pressure pump, feeding pipe enters the spray gun of spraying cat head, slurries through atomizing are by the heated-air drying that also flows, thick particle directly falls and enters material-receiving system, tiny particle continues screening by air-introduced machine suction primary cyclone and secondary cyclone, thicker particle falls in primary cyclone, then the high pressure positive blower blowback below it enters to enter material-receiving system in the spray tower, thinner fine powder (measuring fewer) in secondary cyclone, fall enter artificially collect in the rewinding bucket after the anti-glue unit of throwing into into again, swim in fine powder very thin in the air and be incorporated into spray scrubber through blower fan and carry out cleaning dust.Need a high pressure positive blower that the blowback that falls in the one-level cyclone is entered to enter material-receiving system in the spray tower in this technique.A high pressure positive blower needs to consume a large amount of electric energy every year, has increased the production cost of factory.
The utility model content
The utility model is in order to overcome deficiency of the prior art, to provide a kind of and can save the dry spraying system of the catalytic cracking catalyst that takes up an area space and energy consumption.
The utility model for achieving the above object, be achieved through the following technical solutions, the dry spraying system of a kind of catalytic cracking catalyst, comprise spray tower, at the spray tower top hot air distributor is housed, spray tower inner chamber top is equipped with spray gun, one-level, secondary cyclone, described primary cyclone discharging opening is connected with Pneumatic butterfly valve, the secondary cyclone discharging opening is connected with Hand-operated butterfly valve and rewinding cylinder in turn, it is characterized in that: described one-level, the height and position of secondary cyclone discharging opening is greater than the height of spray tower lower taper recovering hopper, and described primary cyclone discharging opening is communicated with spray tower lower taper recovering hopper bottom by pipeline.
Described primary cyclone discharging opening is the inclined tube setting with the pipeline that spray tower lower taper recovering hopper bottom is communicated with, and its gradient is that pipe centerline and spray tower central axis are acute angle.
Described primary cyclone discharging opening is DN100-DN200 with the pipe diameter that spray tower lower taper recovering hopper bottom is communicated with.
Beneficial effect: can save a high pressure positive blower in the technological process, 1 year can be for unit saves several ten thousand yuan of electricity consumptions, and can save ground space.

Among the figure: 1, hot air distributor, 2, spray gun, 3, spray tower, 3-1, taper recovering hopper, 4, air-introduced machine, 5, the one-level whirlwind, 6, the secondary whirlwind, 7, Hand-operated butterfly valve, 8, the rewinding cylinder, 9, Pneumatic butterfly valve, 10, pipeline.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, the dry spraying system of a kind of catalytic cracking catalyst, comprise spray tower 3, at the spray tower top hot air distributor 1 is housed, spray tower inner chamber top is equipped with spray gun 2, one-level, secondary cyclone 5,6, described primary cyclone discharging opening is connected with Pneumatic butterfly valve 9, the secondary cyclone discharging opening is connected with Hand-operated butterfly valve 7 and rewinding cylinder 8 in turn, described one-level, the height and position of secondary cyclone discharging opening is higher than the height of spray tower lower taper recovering hopper 3-1, and described primary cyclone discharging opening is communicated with spray tower lower taper recovering hopper bottom by pipeline 10.Described primary cyclone discharging opening is the inclined tube setting with the pipeline that spray tower lower taper recovering hopper bottom is communicated with, and its gradient is that pipe centerline and spray tower central axis are acute angle.Described primary cyclone discharging opening is DN100-DN200. with the pipe diameter that spray tower lower taper recovering hopper bottom is communicated with
The course of work
To be positioned at the cyclone integral raising on ground, be in the middle and upper part of tower body with the junction of tower body, then connect the top that an inclined tube (DN100-200) is connected to the tower body baiting valve at the feed opening place of one-level cyclone.Thicker particle is declined to the bottom at the one-level cyclone, then flow directly into the product that the top of the baiting valve of spray tower falls by the effect of potential energy in spray tower and enter material-receiving system.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
