Description
УСТАНОВКА ГИДРОСЕПАРАЦИИ ТВЕРДЫХ КОММУНАЛЬНЫХ ОТХОДОВ SOLID WASTE HYDRAULIC SEPARATION PLANT
Полезная модель относится к области переработки отходов во вторичное сырьё, а именно, к установкам для жидкостного разделения твердых коммунальных отходов, и может быть использована при утилизации бытового мусора. The utility model relates to the field of processing waste into secondary raw materials, namely, to installations for the liquid separation of municipal solid waste, and can be used in the disposal of household waste.
Из уровня техники известна установка гидросепарации твердых коммунальных отходов, содержащая приемный короб с вертикальной подачей, погружной барабан, наполняемую оборотной водой ванну с выходным патрубком, цепной транспортер для легкой фракции и наклонный шнековый транспортер для тяжелой фракции (см. публикацию W02015070535, кл. В03В5/66, опубл. 21.05.2015). Недостатками известного устройства являются относительно низкое качество разделения и быстрый выход из строя ввиду застревания агломератов в деталях механизма. From the prior art, there is a plant for the hydroseparation of solid municipal waste, comprising a receiving box with vertical feed, a submersible drum, a bath filled with circulating water with an outlet, a chain conveyor for light fraction and an inclined screw conveyor for heavy fraction (see publication W02015070535, class B03B5 / 66, publ. 05/21/2015). The disadvantages of the known device are the relatively low quality of separation and quick failure due to the sticking of agglomerates in the details of the mechanism.
Технической проблемой является устранение указанных недостатков и создание простой и надёжной гидросепарирующей установки.The technical problem is the elimination of these disadvantages and the creation of a simple and reliable hydroseparating unit.
Технический результат заключается в повышении эффективности разделения отходов. Поставленная задача решается, а технический результат достигается тем, что установка гидросепарации твердых коммунальных отходов, содержащая приемный короб с вертикальной подачей, погружной барабан, наполняемую оборотной водой ванну с выходным патрубком, цепной транспортер для легкой фракции и наклонный шнековый транспортер для тяжелой фракции, снабжена блоком подачи оборотной воды с абразивом, оборудованным помпой и

Цепной транспортер предпочтительно снабжён щётками и выполнен с горизонтальным участком, расположенным таким образом, что при прохождении по нему щётки частично погружены в оборотную воду. Выходная часть шнекового транспортёра предпочтительно расположена выше уровня оборотной воды, а дно ванны под шнековым транспортёром выполнено с тем же наклоном, что и сам шнековый транспортёр. The technical result consists in increasing the efficiency of waste separation. The task is solved, and the technical result is achieved by the fact that the installation of hydroseparation of solid municipal waste, containing a receiving box with a vertical feed, a submersible drum, a bath filled with circulating water with an outlet pipe, a chain conveyor for light fraction and an inclined screw conveyor for heavy fraction, is equipped with a block circulating water supply with an abrasive equipped with a pump and pressure nozzles installed inside the receiving box and directed to the immersion drum. The chain conveyor is preferably equipped with brushes and is designed with a horizontal section arranged in such a way that, when passing through it, the brushes are partially immersed in circulating water. The outlet of the auger conveyor is preferably located above the level of the circulating water, and the bottom of the bath under the auger conveyor is made with the same slope as the auger conveyor itself.
На фиг.1 представлен общий вид предлагаемой установки; на фиг.2 — то же в разрезе. Figure 1 shows a general view of the proposed installation; figure 2 - the same in section.
Предлагаемая установка представляет собой ванну 1 из нержавеющей стали, наполненную оборотной водой. Через приёмный короб 2 в установку вертикально поступают первично отсортированные «хвосты» твердых коммунальных отходов размером 50x50x50 мм плотностью 5,7 м3/тн ±20% (подрешеточная фракция), частично разбиваясь при ударе о дно короба. The proposed installation is a stainless steel bath 1 filled with circulating water. Primarily sorted “tails” of solid municipal waste 50x50x50 mm in size with a density of 5.7 m 3 / t ± 20% (sublattice fraction) vertically enter the installation through the receiving box 2, partially breaking when hitting the bottom of the box.
В коробе 2 установлены погружной барабан 3 и направленные на него напорные форсунки 4, подключенные к блоку подачи оборотной воды с абразивом на основе помпы (на чертеже не показаны). Через форсунки 4 под высоким давлением подается оборотная вода для размывания отходов и очистки барабана 3. Дополнительно форсунки 4 оборудованы эжекторами, через которые подается смесь оборотной воды с абразивом (песком со дна ванны 1, ПАВ или другими реагентами), что значительно увеличивает эффективность промывки и разделения отходов на фракции. Лопастями погружного барабана 3 отходы притапливаются и происходит
размывание пищевых отходов в оборотной воде, отделение тяжелой фракции и легкой. In the box 2, a submersible drum 3 and pressure nozzles 4 directed at it are installed, connected to a circulating water supply unit with an abrasive based on a pump (not shown in the drawing). Through nozzles 4, high-pressure circulating water is supplied to wash waste and clean drum 3. Additionally, nozzles 4 are equipped with ejectors, through which a mixture of circulating water with abrasive (sand from the bottom of the bath 1, surfactant or other reagents) is supplied, which significantly increases the efficiency of washing and separation of waste into fractions. By the blades of the submersible drum 3, the waste is melted and erosion of food waste in circulating water, separation of heavy and light fractions.
Тяжелая фракция тонет и извлекается из установки полупогружным наклонным шнековым транспортером 5 из нержавеющей стали, выходная часть которого расположена выше уровня оборотной воды, чтобы избежать перелива. Для эффективного захвата тяжёлой фракции дно ванны 1 под шнековым транспортёром 5 выполнено с тем же наклоном, что и он сам и может быть снабжено полуцилиндрическим желобом соответствующего радиуса. The heavy fraction sinks and is removed from the installation by a semi-submersible inclined screw conveyor 5 made of stainless steel, the outlet of which is located above the level of circulating water to avoid overflow. To effectively capture the heavy fraction, the bottom of the bath 1 under the screw conveyor 5 is made with the same slope as it itself and can be equipped with a semi-cylindrical chute of the corresponding radius.
Легкая фракция всплывает и извлекается щётками 6 цепного транспортера 7 легкой фракции с поверхности зеркала оборотной воды. Для более эффективного сбора цепной транспортер 7 выполнен с горизонтальным участком 7', расположенным таким образом, что при прохождении по нему щётки 6 частично погружены в воду, что позволяет дополнительно промывать отходы в процессе транспортировки. Лоток 8 для поднятия легкой фракции погружен в воду, тем самым препятствует попаданию отходов с положительной плавучестью в систему механической очистки оборотной воды, не засоряя ее и повышая качество легкой фракции. The light fraction floats and is removed by the brushes 6 of the chain conveyor 7 of the light fraction from the surface of the mirror of circulating water. For more efficient collection, the chain conveyor 7 is made with a horizontal section 7 ', located in such a way that, when passing through it, the brushes 6 are partially submerged in water, which makes it possible to additionally wash the waste during transportation. Tray 8 for raising the light fraction is immersed in water, thereby preventing waste with positive buoyancy from entering the mechanical treatment system of circulating water, without clogging it and increasing the quality of the light fraction.
Оборотная вода, насыщенная размытыми пищевыми отходами, через выходной патрубок 9 направляется на механическую очистку с использованием шнековой решетки, где извлекаются частицы размером больше ячеек сита (от 0,25 мм до 5 мм). Recycled water, saturated with eroded food waste, through the outlet pipe 9 is directed to mechanical cleaning using a screw grate, where particles larger than the mesh of the sieve are removed (from 0.25 mm to 5 mm).
Благодаря исходному интенсивному размыванию смешанного мусора в приёмном коробе 2 оборотной водой с абразивом, подаваемыми через форсунки 4, значительно упрощается его последующее разделение. Кроме того, практически полностью исключается вероятность заклинивания
барабана 3 из-за налипания мусора, что также положительно влияет на эффективность разделения. Предлагаемая установка может быть использована для гидросепарации твёрдых коммунальных отходов с целевой производительностью от 1 до 20 тн/ч, в том числе с целью получения альтернативного топлива и/или в качестве основного элемента комплекса рекультивации полигонов ТБО (твердых бытовых отходов).
Due to the initial intensive washing out of the mixed waste in the receiving box 2 with circulating water with abrasive supplied through nozzles 4, its subsequent separation is greatly simplified. In addition, the possibility of jamming is almost completely eliminated. drum 3 due to the adhesion of debris, which also has a positive effect on the separation efficiency. The proposed installation can be used for the hydroseparation of solid municipal waste with a target capacity of 1 to 20 t / h, including for the purpose of obtaining an alternative fuel and / or as the main element of a complex for the reclamation of solid waste landfills (solid domestic waste).
