SU135092A1 - Device for heating gases and air with a suspended bed - Google Patents

Description

A device is proposed for heating gases and air with a hanging and flowing layer.

The device is designed as a sectional mine cure, which ensures a constant level of the heat exchange nozzle at each section diaphragm, regardless of the gas flow.

FIG. 1 shows the proposed device, the general view; in fig. 2 - section along A-A; in fig. 3 - section along BB.

The heat exchanging granulated and precipitation is heated in a suspended-flowing layer in the heating sections Y, 2 and 5 by a stream of combustion products of gaseous or liquid fuel formed in the combustion chamber 4. The cooling of the same nozzle is also carried out in the blowing layer in the cooling sections 5, -6, 7, and 8, where heat is transferred to the heating gas or air flow. Fuel is burned by the burners 9 in the air stream coming from the annular air duct 10.

The granulated heat-mashing material from the intermediate bin // through the overflow channel 12 enters by gravity into the first section /, where it is processed in the inflated flowing layer, and gradually goes down from the chamber into the inlet opening / 5 in the diaphragm of the hearth M and the overflow channel 15 in the bed 16. getting into the unloading section 17.

The height of the fluidized bed is self-regulating and retains its constant value, since it is related to the level of the horizon of the outlet of the overflow channel 18.

The supply of heated gas or muzdukh from the ring pipe 19 is made by trophies 20, and the selection of heated gas or air through the outlets 21, where further on their way fine dust removal filters can be installed if necessary. Waste products

No 135092-2 combustion through the chimney 22, which is located under the metal 23, is supplied through the duct 24 to the pneumatic peeler assembly. At the pipeline 25 from the discharge chamber 17 through the throttling hole 26 enters the heat transfer granulated material. The latter is fed through the pneumatic conveying pipe 27 into the intermediate bunker 11, and finally giving up physical heat and passing the baffle 2f and the dust collector 29, goes into the atmosphere through the upper gas pipeline 30. The dust is removed through the dust pipe 31. The cylindrical gas-air heaters are made of standard concrete and; 1 and reinforced concrete sections 32 to the same standard diaphragm sections of subspecies 14, encased by a common clutch 16 with insulation.

Subject invention

A device for heating gases and air with a gas-implanted layer, characterized by the fact that, in order to ensure constant heat buildup on each section diaphragm independently of the gas flow, the device is designed as a section niaxTHO & furnaces with overflow channels between sections, with a face, with a round heat exchange nozzle, with a fuel combustion chamber and with a discharge section, which is connected to a via hopper by means of a tubular pneumatic conveyor.
