(54) ПЕЧЬ ДЛЯ СЖИГАНИЯ ОТХОДОВ(54) OVEN FOR WASTE BURNING

II

Изобретение относитс к устройствам дл сжигани древесных отходов, не подлежащих утилизации, и может быть применено при сжигании отходов, например, модельно-. го и мебельного производства с одновременным получением вторичных энергоресурсов.The invention relates to incinerators for non-recyclable wood waste, and can be applied to waste incineration, for example, model waste. go and furniture production with simultaneous production of secondary energy resources.

Известна печь дл сжигани отходов, включающа камеру сгорани , горелки, камеру дожигани и газоход 1.A famous waste incineration furnace, including a combustion chamber, burners, afterburner and flue 1.

Недостаток известной печи состоит в низкой производительности, так как отходы лежат плотным слоем и доступ воздуха к ним затруднен, в результате чего отходы гор т очень медленно (тлеют) и сгорают не пол-, ностью.A disadvantage of the known furnace is low productivity, since the waste lies in a dense layer and air access to them is difficult, as a result of which the waste burns very slowly (smolders) and does not burn completely.

Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту вл етс устройство дл сжигани отходов, включающее загрузочный бункер, камеру сгорани , горелки, камеру дожигани , ворощильные устройства 2.The closest to the proposed technical essence and the achieved effect is a device for waste incineration, including a hopper, a combustion chamber, burners, afterburner, voroshilny devices 2.

Недостаток указанного устройства заключаетс в малой скорости горени , в основном , на поверхности сло , так как ворощильные устройства (Н1уру«)щие планки) недостаточно эффективно перемещивают больЩОЙ слой ОТХОДОЕЗ.The disadvantage of this device lies in the low burning rate, mainly on the surface of the layer, since the winding devices (NIuru) strips do not effectively move a large layer of WASTE.

Цель изобретени - повышение эффективности работы печи.The purpose of the invention is to increase the efficiency of the furnace.

Поставленна цель достигаетс тем, что в печи дл сжигани отходов, содержащей загрузочную течку, камеру сгорани с горелками , ворощильные устройства, камеру дожигани и устройство дл выгрузки, ворощильные устройства установлены р дами и выполнены двух видов: одни в виде полых валов , установленных поперек печи, с укрепленными на них по винтовой линии со смещением относительно друг друга планкамилопаст ми , а другие в виде размещенных в подине воздушных сопел, расположенных между р дами первого вида ворощильных 5 устройств.This goal is achieved by the fact that in a waste incinerator containing a charging chute, a combustion chamber with burners, razholilnye devices, an afterburner and a discharger, voroshchilnye devices are installed in rows and are of two types: one in the form of hollow shafts installed across the furnace , with plank-shaped blades shifted relative to each other, and others in the form of air nozzles located in the hearth, located between the rows of the first type of 5-piece heads, mounted on them.

На фиг. 1 представлена печь, общий вид; на фиг. 2 - то же, поперечный разрез.FIG. 1 shows the oven, general view; in fig. 2 - the same cross section.

Claims

The waste incinerator contains a charging chute I, a combustion chamber 2 equipped with burners 3. Mechanical agitators 4 are installed across the combustion chamber 2 arranged in rows and made in the form of hollow shafts 5, on which they are fixed along the generators along the helix the blades 6 each other. Between the rows of mechanical turners 4 in the inclined bottom 7 of the chamber 2, there are pneumatic turners 8 arranged in the form of air nozzles. The afterburning chamber 9 is separated from the chamber, 2 combustion by a dividing wall 10, designed to reduce the removal of non-burnt sawdust, at the bottom of which there is a discharging device 11 and a disposal device. The furnace works as follows. Sawdust through the charging chute 1 enters the combustion chamber 2 into the high temperature zone formed by the burners 3. The unburned sawdust enters the inclined lodge 7. The air required for burning the sawdust partially flows through the burners 3, and mostly through pneumatic Voroshitol 8, which Intensify the combustion process by supplying air oxygen directly to the burning sawdust. To eliminate large accumulations of sawdust, mechanical agitators 4 are used, which scatter them in an even layer along the bottom 7 of the combustion chamber 2. In order to reduce dead space and more uniform mixing of sawdust over time, the blade slats 6 of the agitators 4 are installed in rows along a helical line so that, starting spreading from one wall of chamber 2, they switch to another, while the next the slat-blade begins to scatter again at the first wall, etc. gradually as it burns; Sawdust moves along an inclined hearth 7 in the direction of the afterburner chamber 9, in which individual soaring burning sawdust is also deposited, which fall from the chamber 2 and, hitting the dividing wall 10, change the trajectory and speed. From chamber 9 after-burning, ash is evacuated by device II. The design of the proposed furnace makes it possible to intensify the combustion process while at the same time obtaining secondary energy resources, increase the combustion efficiency of the waste and, thus, increase the efficiency of the furnace operation. Claims An incineration furnace comprising a feed chute, a burner with burners, agitators, an afterburner, and an unloading device, characterized in that, in order to improve performance, the agitators are installed in two different types; one in the form of hollow shafts installed across the furnace, with helical blades offset from one another by means of helical blades mounted on them, and others in the form of air nozzles located in the hearth, located between the rows of the first type of agitators.
