Embodiment Construction

[0038] attachedfigure 1 It is the working principle diagram of HY type retort furnace. The figure shows that the material is fed from the upper part of the retort furnace and enters the silo 1. The I gate valve 2 is opened, and the material enters the hopper 3. When the hopper 3 is full of materials, the I gate valve 2 is closed. , Open the gate valve 4 of the lower II gate of the hopper, and the material falls into the carbonization furnace by its own weight. When not feeding, the Ⅱ gate valve 4 is closed. This double ram blanking method can prevent the gas in the furnace from escaping out of the furnace through the hopper and the air outside the furnace from entering the furnace through the hopper. After the material enters the retort furnace, it first passes through the preheating drying chamber 5. In the preheating drying chamber 5, the material is heated to 200°C-250°C by the retort gas of 500°C-550°C sprayed from the gas chamber 6, and the material contains The water is...

Abstract

The invention discloses an HY type dry distillation furnace which is characterized by comprising a plurality of dry distillation subunits, wherein each dry distillation subunit comprises a charging device, an oil gas discharge device, a dry distillation device, a heating device and a coke discharge device; materials are subjected to dry distillation by using a combined radiation heat exchange and convection heat exchange mode in the furnace; gas generated in a dry distillation process is used as a dry distillation heat source, and the dry distillation heat can be self-balanced; the materials are directly heated by virtue of radiation of a furnace wall of a combustion chamber, and a heat carrier does not need to be subjected to secondary heating and long-distance conveying; a dry distillation gas outputting device is arranged in the furnace, so that the gas in the furnace flows smoothly; coke is discharged by a dry method. The dry distillation furnace is high in heat utilization efficiency, low in outlet gas quantity, low in water consumption, high in oil yield and large in daily treatment capacity capable of being more than 6,000 tons, and is suitable for low and medium-temperature dry distillation of the materials such as oil sand, oil shale, coal and the like, and suitable for oil refining and dry distillation of large particle materials and small particle materials of less than 15mm.

Description

technical field [0001] The invention relates to a dry distillation furnace which heats materials by means of radiation, exports dry distillation gas layer by layer, and adopts a dry method to discharge coke. It is suitable for medium and low temperature carbonization and refining of materials with various particle sizes, including small particles of oil shale, oil sand and coal. Background technique [0002] At present, the medium and low temperature dry distillation furnaces for materials in China cannot handle small particle materials, resulting in a large waste of resources. Generally, the oil shale, coal, oil sand, etc. extracted from mines have a particle size of less than 12mm, accounting for about 20% to 30%, and the high ones reach 40% to 50%. There are three kinds of medium and low temperature retort furnaces that are widely used. The first one is the Fushun type retort furnace, which has a cylindrical structure and is an internal combustion furnace. It uses a reg...
