Description
Technical field
The utility model relates to urea prilling tower dust and reclaims field, is specifically related to a kind of granulation tower dust and reclaims ultrafiltration apparatus.
Background technology
In current most of chemical fertilizer production enterprise, usually very important carbamide dust and ammonia is all entrained with in the tail gas of urea prilling tower, some enterprise is in order to profit-push is when original granulation tower is constant, expand the scale of production, the harmful substances such as the tail gas dust of granulation tower discharge also increase with the expansion of output, tail gas containing a large amount of dust is thrown in air, not only causes great waste, but also causes the environment near granulation tower and have a strong impact on.
It is use sprinkler absorbing liquid and packing material absorbing that traditional carbamide dust reclaims, solve the problem that carbamide dust pollutes to a great extent, but this device dust recovery rate is low, and urea particle has temperature rise, and can with steam in the gas of discharging, containing a small amount of urea liquid in steam, still pollute the environment.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is to provide a kind of high efficiency ultrafiltration device, has dust recovery rate high, and urea particle reclaims ultrafiltration apparatus without the granulation tower dust of temperature rise.
The utility model solves the technical scheme that its technical problem adopts: a kind of granulation tower dust reclaims ultrafiltration apparatus, comprise between granulation, separated space, operation room, feeder, described feeder to be positioned between granulation immediately below air outlet, described feeder is vertically provided with shutter outward, described feeder has operation room, water circulating pump is provided with in described operation room, circulating slot, described feeder is connected with circulating slot by pipeline, described circulating slot is connected with water circulating pump by pipeline, described water circulating pump connects multiple Flushing nozzle by pipeline, between described granulation, top outlet inlet is provided with separated space, blower fan is provided with above described separated space, between described granulation, top outlet inlet place is connected with ultrafiltration core by stainless steel rebar net, described ultrafiltration core makes continuously " V " font by high polymer, " U " font or " people " font corrugated surface, Flushing nozzle is evenly distributed with around described ultrafiltration core.
Further, described shutter is upwards connected to air outlet lower edge place, and formed between described shutter, feeder, air outlet and absorb space, the blade of described shutter near the side absorbing space is downward-sloping.
The utility model has following beneficial effect: simple and reasonable, adopt spray, filter, washing combination, improve recovering effect, louvered design effectively can increase area of passage, reduce the air velocity containing dust, make fully to contact with defluent circulating absorption solution in absorption space containing dust air, improve detersive efficiency, ultrafiltration core makes continuously " V " font or " U " font corrugated surface by high polymer, effective increase adsorption area, dust-filtering precision is 0.1 μm to 60 μm, organic efficiency reaches 99%, ammonia recovery 100%, urea particle is without the feature of temperature rise, both urea had been reclaimed, stop again atmosphere pollution.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure between 1 granulation, 2 water circulating pumps, 3 operation rooms, 4 circulating slots, 5 feeders, 6 absorb space, 7 ultrafiltration core, 8 separated spaces, 9 blower fans, 10 pipelines, 11 shutters, 12 Flushing nozzles.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.
A kind of granulation tower dust as shown in Figure 1 reclaims ultrafiltration apparatus, to comprise between granulation 1, separated space 8, operation room 3, feeder 5, described feeder 5 to be positioned between granulation immediately below 1 air outlet, described feeder 5 is outer is vertically provided with shutter 11, described feeder 5 has operation room 3, water circulating pump 2 is provided with in described operation room 3, circulating slot 4, described feeder 5 is connected with circulating slot 4 by pipeline 10, described circulating slot 4 is connected with water circulating pump 2 by pipeline 10, described water circulating pump 2 connects multiple Flushing nozzle 12 by pipeline 10, between described granulation, 1 top outlet inlet is provided with separated space 8, blower fan 9 is provided with above described separated space 8, between described granulation, 1 top outlet inlet place is connected with ultrafiltration core 7 by stainless steel rebar net, described ultrafiltration core 7 makes continuously " V " font by high polymer, " U " font or " people " font corrugated surface, Flushing nozzle 12 is evenly provided with around described ultrafiltration core 7.
Further, described shutter 11 is upwards connected to air outlet lower edge place, is formed and absorb space 6 between described shutter 11, feeder 5, air outlet, and the blade of described shutter 11 near the side absorbing space 6 is downward-sloping.
Operation principle of the present utility model is: described circulating absorption solution adopts urea decomposition of effluent, when granulation tower dust recovery ultrafiltration apparatus is brought into use, first reclaim ultrafiltration apparatus by the Flushing nozzle 12 on top to granulation tower dust and add circulating absorption solution, when circulating slot 4 liquid level reaches 50%, ON cycle water pump 2 topping up is to Flushing nozzle 12, hydrojet is to efficient ultrafiltration core 7, then to dirty, in granulation tower, hot gas rises naturally simultaneously, entered by shutter 11 and absorb space 6, shutter 11 effectively can increase area of passage, reduce containing dust air velocity, make fully to contact with defluent circulating absorption solution in absorption space 6 containing dust air, improve detersive efficiency, gas continues to rise under the gravitation of blower fan 9, by ultrafiltration core 7, powder dust particle in gas does inertia motion or irregular movement with gas, high polymer is collided in motion process, particle is adsorbed by high polymer, air afterwards containing steam is by separated space 8, after steam is separated from the gas, the gas meeting discharge standard requirement is discharged outside tower, completely solve and absorb drop by the problem of taking out of outside tower, enter feeder 5 from the circulating absorption solution ultrafiltration core 7 spray simultaneously, being flowed into by pipeline 10 is located in the circulating slot 4 of operation room 3, again through water circulating pump 2 pressurize laggard enter ultrafiltration core 7 carry out absorbing and filtering, when in absorbing liquid to be recycled, urea content reaches finite concentration, entered Urea Evaporation System to be reclaimed, by spray, filter, washing combination, effectively improve recovering effect.
The utility model is not limited to described embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
