Abstract

FIELD: equipment for transfer of solid particles. SUBSTANCE: solid particles are carried from first chamber (combustion chamber of fluidized layer reactor) to adjacent second chamber (for example, transfer chamber and/or working chamber), thus ensuring seal for solid particle flow, adjustable valve for solid particle flow or both of them at chamber interface. Carrier gas is admitted inside first chamber to transfer solid particles from first chamber to second one as several flows of solid particles. Several narrow passages in dividing partition arranged one above other have relationship of height to length not exceeding 0.5 at height not exceeding 50 mm are used as seal for flow of solid particles and adjustable valve for flow of solid particles in partition. Carrier gas may be introduced through lower portion of first chamber and/or lateral wall located opposite dividing partition; dividing partition may be lined with refractory material near first chamber with passages in refractory lining made of combustible material which are burnt through during heating of refractory lining. Besides that, passages may be slightly inclined from first chamber to second one, for example at angle of 15 deg. EFFECT: enhanced efficiency.

Согласно изобретению твердые частицы транспортируются из первой камеры (камеры сгорания реактора кипящего слоя) в соседнюю вторую камеру (например, камеру переноса и/или рабочую камеру), обеспечивая уплотнение для потока твердых частиц, регулируемого клапана для потока твердых частиц или того и другого в месте раздела камер. Транспортирующий газ вводится во внутрь первой камеры, чтобы осуществить перенос твердых частиц как несколько потоков твердых частиц из первой камеры во вторую камеру. Ряд узких проходов в разделительной перегородке, расположенных один над другим и имеющих соотношение высоты к длине не более 0,5 при высоте не более 50 мм, используются в качестве уплотнения для потока твердых частиц и регулируемого клапана для потока твердых частиц в перегородке. Транспортирующий газ может быть введен через нижнюю часть первой камеры и/или боковую стенку, расположенную напротив разделительной перегородки, а разделительная перегородка может быть облицована огнеупорным материалом рядом с первой камерой с проходами в огнеупорной облицовке, изготовленными из горючего материала, которые прожигаются во время прогрева огнеупорной облицовки. Кроме того, проходы могут быть слегка наклонены от первой камеры к второй камере, например, под углом 15 градусов.According to the invention, the solid particles are transported from the first chamber (the combustion chamber of the fluidized bed reactor) to an adjacent second chamber (for example, a transfer chamber and / or a working chamber), providing a seal for the flow of solid particles, an adjustable valve for the flow of solid particles, or both in place camera section. The carrier gas is introduced into the inside of the first chamber in order to carry out the transfer of solid particles as several streams of solid particles from the first chamber to the second chamber. A series of narrow passages in the separation wall, located one above the other and having a height to length ratio of not more than 0.5 and a height of not more than 50 mm, are used as a seal for the flow of solid particles and an adjustable valve for the flow of solid particles in the partition. The carrier gas may be introduced through the bottom of the first chamber and / or the side wall opposite the partition wall, and the partition wall may be lined with refractory material near the first chamber with passages in the refractory lining made of combustible material that are burned during heating of the refractory facing. In addition, the passages can be slightly inclined from the first chamber to the second chamber, for example, at an angle of 15 degrees.
