An immersion melter

Abstract

The invention provides an immersion type fusion apparatus. An annular pipe basket with a steam inlet and a steam condensate outlet is put in a vertical cylinder, the lower part of the vertical cylinder is a tapered head or an oval head, and the upper part is a flat-bottom head; a solid material inlet is installed at the flat-bottom head, a stirring device is installed in the annular pipe frame, and the vertical cylinder employs a form of an inner jacket cylinder or an outer coil-pipe cylinder; the annular pipe frame possesses 1-4 upper annular pipes and 1-4 lower annular pipes, the upper annular pipes are in connection and steam is introduced into the upper annular pipes, the lower annular pipes are in connection and are connected with a condensate-water discharge pipe, and vertical pipes are arranged between the upper and lower annular pipes; and the annular pipe frame is fixedly disposed on the bottom head by a fixing support. The heater is low in cost, high in thermal efficiency and low in energy consumption and operation cost, and is capable of effectively preventing aggregation and caking phenomena of materials during heating, equipment tail gas discharge is less, environmental pollution is small, tail gas processing is simple and practicable, and equipment installation and debugging are simple.

Description

technical field [0001] The invention relates to the technical field of melting equipment for organic and inorganic solid materials in chemical production, in particular to a submerged melter. Background technique [0002] In the chemical production process, especially in the production process of compound fertilizer, sulfuric acid, urea and stearyl chloride, organic and inorganic solid materials such as urea, sulfur, ammonium nitrate and stearic acid need to be melted quickly to meet the needs of process production. When melting granular urea, the content of biuret should be controlled. If the content of biuret exceeds the standard, it will cause seedling burning; when melting ammonium nitrate, there will be a possibility of fire or explosion, and there is a certain danger. Fully consider the safety of the equipment. The melting equipment in the prior art has low thermal efficiency. After the solid material is added, it cannot be melted quickly, resulting in deterioration ca...
