Furnace body structure of cylindrical rotary thermal equipment

Abstract

Provided is a furnace body structure of cylindrical rotary thermal equipment. A furnace body is divided into a feed low-temperature section, a high-temperature thermal reaction section and an outlet flowing port section; down-draft material retaining rings protruding out of the surface of a kiln liner of the high-temperature thermal reaction section are arranged at the position where the high-temperature thermal reaction section is connected with the feed low-temperature section and the position where the high-temperature thermal reaction section is connected with the outlet flowing port section; the down-draft material retaining rings are formed in the mode that a plurality of material retaining blocks encircle the furnace body in a staggered mode; the material retaining blocks are anchored on the furnace body through anchoring parts after a plurality of layers of anchoring bricks are overlapped. As the down-draft material retaining rings protruding out of the surface of the kiln liner of the high-temperature thermal reaction section are arranged at the position where the high-temperature thermal reaction section is connected with the feed low-temperature section and the position where the high-temperature thermal reaction section is connected with the outlet flowing port section, more heat at a high-temperature area is gathered at the high-temperature area and is reflected on a kiln coating, the speed of materials becomes slow when the materials pass through the material retaining rings, the staying time of the materials at the high-temperature area is prolonged, and the utilization rate of heat is improved.

Description

technical field [0001] The invention relates to rotary heat equipment, in particular to a furnace body structure of a cylindrical rotary heat equipment. Background technique [0002] In the heating field of various industries, it is widely used in the rotary heating equipment with kiln lining installed inside the cylindrical steel shell, also known as rotary kiln, rotary dryer, rotary roasting furnace, rotary calciner and so on. The furnace body of traditional rotary heat equipment is generally divided into three sections of low-temperature feeding section, high-temperature thermal reaction section and outlet orifice with different temperatures. Since the temperature of the three sections is different, the moving speed of the material in these three sections is basically the same, so that the residence time of the material in the high-temperature thermal reaction section is relatively short, and when the material is transferred from the high-temperature thermal reaction sect...
