Abstract
The utility model discloses an urea prilling tower dust recovery device, including setting up the collecting vat in urea prilling tower below, the below of collecting vat is equipped with the discharging pipe, in the lower extreme of discharging pipe stretches into a circulating slot, be equipped with an urine return line on the circulating slot, install the circulating pump on the urine return line, still be equipped with a collection box, the collection box passes through pipeline and circulating slot intercommunication, it hydrolysises the waste liquid and advances the pipe still to be equipped with one in the circulating slot. The utility model discloses an urea prilling tower dust recovery device simple structure, reasonable in design, urea dust recovery efficiency is good, and economic benefits and social are obvious, and the construction installation is simple, and maintenance cost is very little, and the working costs only contains circulating water pump and fluid infusion water pump power consumption, reduce cost, pollution abatement again promptly.
Description
Technical field
The utility model relates to agricultural technology field, particularly a kind of urea granulation tower powder/dust reclaiming device.
Background technology
At present, urea mainly as agricultural fertilizer, and is occur in the form of granules commercially substantially.Carbamide granulation mainly uses two kinds of methods.One is tower granulation, namely utilizes the rotary prilling sprayer being arranged on granulation tower top to be sprayed in granulation tower by molten urea solution, the urea granules cooling that the cold air that tower bottom enters will decline, and packs sale after then collecting at the bottom of tower.Two is mechanical type granulation (such as: cylinder granulation, fluidized bed prilling etc.), by being sprayed on crystal seed after urine atomization, crystal seed is constantly grown up, and after particle reaches the size of needs, discharger packaging is sold.Tower granulation generally takes gravity-flow ventilation form, and its advantage is that energy consumption is low, and plant maintenance cost of use is low.Shortcoming is: due to the impact of the viscosity and surface tension and cooling velocity that are subject to urine, particle size is little to be restricted (be generally referred to as granule, particle diameter is 1 ~ 3mm).And adopt the disposable type of cooling of nature, the compression strength of urea granules is relatively low, meanwhile, in the emission gases at granulation tower top, inevitably take away a certain amount of carbamide dust and fine particle, air is polluted and loses with certain urea product.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of urea granulation tower powder/dust reclaiming device that can solve the problem.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of urea granulation tower powder/dust reclaiming device, comprise the feeder be arranged on below urea prilling tower, the below of described feeder is provided with discharge nozzle, the lower end of discharge nozzle is stretched in a circulating slot, described circulating slot is provided with a urine recovery channel, described urine recovery channel is provided with circulating pump, also be provided with a collection box, described collection box is communicated with circulating slot by pipeline, is also provided with a waste hydrolyzed liquid inlet pipe in described circulating slot.
As further improvement of the utility model, in described circulating slot, be provided with an overflow pipe.
As further improvement of the utility model, in described collection box, be provided with filter course.
The beneficial effects of the utility model are: urea granulation tower powder/dust reclaiming device structure of the present utility model is simple, reasonable in design, carbamide dust organic efficiency is good, economic benefit and social benefit obvious, construction and installation are simple, and maintenance cost is very little, and operating cost only comprises water circulating pump and fluid infusion electrical power consumption of water pump, namely reduce costs, again decreasing pollution.
