Abstract

A heat exchanger in a manner that is a container for exchange. Solid particle heat with gas For example For heating up raw materials It was initially combustion by using hot gas to feed the container. Which consists of A hollow cylindrical center (1) with a contact gas inlet (3), a conical base (2) with a solid outlet (5), and a downward gas outlet (4), section. Concave top (7, 7 ') facing the center. And with at least one entrance of solid substance (8) The downward gas exit (4) was formed axially. At the beginning it was the center tube in the side of the container. And shall have male tabs (6) with the height of the upper part, the distance of the solid inlet from the vertical axis of the exchanger. Change in heat And the angle at the entrance of the solids to the level, the height of the pipeline The center gas inlet (4) above the lower end of the center (1) of the container and the angle that the male bar (6) makes to the level is all determined. In order to provide optimum conditions, partly for the counter radial heat exchange between the solid substance and the gas, and part for the separation of the solid substance from the gas stream inside the container due to Axial downward velocity of gas With in the contact line

Claims (2)

1. Heat exchanger in the form of a container It has a cylindrical center (1), a sloping conical base (2), and a concave top (7) faces the center and constitutes the upper zone of the heat exchanger, the tangential gas inlet. (3) At the wall of the cylindrical center part and the outlet of the gas located is at least axial when initially facing downward (4), which contributes to gas flow inside the container The heat-resisting edge (6) mounted at the upper end of the gas outlet (4) and at an angle between 40 °C and 70 °C to the horizontal plane. The inlet (8) at least is formed at the top of the vessel and the exit of the solid (5) at the bottom of the vessel. The inlet and outlet of the solid substance are positioned so that the particles solids being fed In a heat exchanger there is a centrifugal momentum in which the solids are transported. While heat exchange with gas through the heat exchanger is countercurrent, the flow with the gas, which travels centrally from the gas inlet (3) to the gas outlet pipe (4), is characterized by the opening of the inlet pipe. Entry of substance (8) at the top of the section, top (7) is attached to the wall of this section. inlet pipe tilted in the same direction as the movement of the gas stream inside the container and it looks like the beta angle that acts on the plane The level is less than 90 o and the appropriate solids inlet location in the level plane is at a distance g ranging from 0 < g < 1.5d from the vertical axis of the heat exchanger, where the chemical formula is the diameter of the base gas outlet pipe. The cone (2) of the chamber is shorter. Such a shortened conical base with the underside of the heat-resisting strip (6) forming an annular cavity (9) together with the tube (4) forms the lower zone of the vessel and the radius b of the center section. (1) having a range of 1.5 d less than or equal to b less than or equal to 3.0 d distance a from the upper end of the gas outlet pipe (4) to the top of the upper part (7) of the heat exchanger has Range from 2 d less than or equal to a less than or equal to 5d gas outlet location Axially is a downward pipe (4) that follows from the axial center, when initially at least its interior inside the vessel and then passes through the conical base (2) of the heat exchanger at a distance f. Within the range 0 is less than or equal to f less than or equal to 2.0d inside the container the center of the cylinder (1) from the level of the lower edge of the part.
