Problems solved by technology

However, this type of structure has its shortcomings that are difficult to overcome. First, the slag introduced into the drum cannot fill the cooling cavity, and the direct heat absorption contact area is small.
The second is that it uses gravity and the friction force of the guide contact surface to damp the sliding movement, which causes a large friction loss on the contact surface, and the equipment fails quickly
The third is that there is almost no layer tumbling process after the hot slag enters the drum, and the thermal contact is uneven. The fourth is that the cooling water rotating interface technolo...

Embodiment Construction

[0021] Due to the swing driving mode, the box body 1 produces a radial inclination angle during the driving process. This inclination angle can generally be controlled between 10° and 30°, so that the box body will generate an axial angle with respect to the horizontal plane. The synthetic inclination angle of the radial angle, so that during the reciprocating rocking process, the high-temperature material in the box will change direction and move according to the azimuth angle given by the heat-absorbing guide piece 1G or the exhaust pipe 1F set in the box, and at the same time The tumbling and moving of the high-temperature material due to the inclination of the inner cavity of the box forms the mixing and exchange position of the high-temperature material in the uniform motion and tumbling, so that the heat-absorbing area and contact time are artificially controlled and enhanced, and the laminar flow and heat conduction resistance are overcome. Hysteresis and other problems ...

Abstract

The slag-cooling machine adopts stable swing balance shaft structure for supporting the hot slag conveyance heat-absorbing box on the machine frame, and adopts swing driving mechanism to make the boxbody reciprocally-swing in tilet angle of 10-30 deg. devialed from centre to make hot stag come into cooling box implement snakelike downslide and rolling along the heat-absorbing water pipe and heat-absorbing guide plate, so that it can greatly increase contacting area of hot slag and heat-absorbing medium and can make hot slag uniformly contact with cooling wall. Said ivnention is simple in structure, its wear abrasion is less and cost is low.

Description

technical field [0001] The invention belongs to a special device for continuously transporting high-temperature solid powder or mixed block high-temperature material. In particular, it is a special device adapted to complete high-efficiency heat exchange while conveying. Background technique [0002] Circulating fluidized beds and boilers have been widely used in metallurgy and power industries. The full combustion of fluidized pulverized coal has achieved excellent economic benefits. The ensuing problem is how to continuously discharge the slag formed after combustion with a temperature above 850°C, and fully recover the large amount of heat energy contained in the hot slag. The supporting device designed to adapt to the above treatment process is called a cold slag machine. At present, the slag cooling machine can be divided into two types: one is called the rotating drum type slag cooling machine, and the other is called the vibrating box type slag cooling machine. Th...
