Description
Естественаа сушка торфа вл етс сезонной операцией. Это обсто тельство резко снижает значение торфа как топлива.Natural peat drying is a seasonal operation. This circumstance sharply reduces the value of peat as a fuel.
Путем р да .исследований вы снеНО , что успешным способом сушки оказалс способ термической обработки торфа с последуюш,им отжатием («а прессах.By means of a number of studies, it was clear that a successful method of drying was a method of heat treating peat followed by squeezing ("in presses.
Суши ость этого способа заключаетс е -следующем.The core of this method is the e-following.
Торф-сырец, насыпанный на полки вагона тонким 1слоем, нагреваетс паром до температуры 190° при давлении 13 ат при этом в торфе происход т структурные изменени . Обработанный таким образом горф при отжатии на прессах доеольно легко отдает влагу (до влажности 40% при начальной влажности 77%).Raw peat poured on the shelves of the car with a thin layer is heated with steam to a temperature of 190 ° at a pressure of 13 at. At the same time, structural changes occur in the peat. Processed in this way, when squeezing out on presses, the gorea easily gives moisture (up to 40% humidity with an initial humidity of 77%).
Однако этот способ имеет много недостатков из-за необходимости примен ть сложное и громоздкое оборудование, как полочные вагоны, вагоны-опрокидыватели, вагоны-нагружатели и т. п.However, this method has many drawbacks due to the need to use complex and cumbersome equipment, such as shelf cars, tipper cars, load carriages, etc.
Учитыва это, дл термической обработки торфа предлагаетс иной способ, Основанный на, так называемом , эффекте взрывл клеток и капилл ров.Taking this into account, for heat treatment of peat offers a different method, based on the so-called effect of cell and capillary explosions.
Суш;ность предлагаемого способа заключаетс в том, что торф «агреваетс до температуры 190° при давлении 12 йг и затем через быстрооткрываюш;еес отверстие выбрасываетс в приемник, где избыточное давление равно- нулю. Вследствие резкого перепада давлений происходит взрыв клеток. Имеюш;а с в торфе влага как свободна , та« и выделивша с -из клеток и капилл ров в значительной часги испар етс , а неиспаривша с легко отжимаетс на прессах при брикетировании отработанной торф ной .The dryness of the proposed method is that the peat is heated to a temperature of 190 ° at a pressure of 12 g and then quickly opened; its opening is thrown into the receiver, where the overpressure is zero. Due to a sharp pressure drop, the cells explode. In the peat, the moisture as free, and that released from the cells and capillaries evaporated for a considerable amount of time, while the non-evaporated are easily squeezed out on the presses when briquetting spent peat.
По это-му способу термическую обработку торфа осуществл ют с одновременной регенерацией тепла происход щего процесса таким образом , что установка по тепловому процессу представл ет замкнутую систему.In this method, heat treatment of peat is carried out with simultaneous heat recovery of the process underway in such a way that the installation by thermal process is a closed system.
На чертеже изображена принци пиальна схемка осуществлени предлагаемого способа.The drawing shows a schematic diagram of the implementation of the proposed method.
В мешальный бассейн 1 при помоши транспортера непрерывно засыпаетс фрезерный торф 77% влажности. Одновременно по трубопроводу 17 подаетс гор ча вода, имеюша темп-ературу 90-96°С. В бассейне / торф достигает влагосодержани 92-95%, а его температура 70-80°. Из бассейна / гор ча масса чер-ез трубопровод 2Milling peat of 77% humidity is continuously poured into the mixing basin 1 with the help of a conveyor belt. At the same time, hot water is supplied via pipeline 17, having a temperature of 90-96 ° C. The pool / peat reaches a moisture content of 92-95%, and its temperature is 70-80 °. From the pool / hot water mass through pipe 2
