Biphenyl thermal adding system

Abstract

The invention discloses a biphenyl thermal adding system, and relates to the field of biphenyl adding devices on textile devices. The biphenyl thermal adding system comprises spinning boxes, biphenyl furnaces, a biphenyl preheating furnace and a waste biphenyl recovery furnace, wherein each spinning box or a plurality of spinning boxes are connected with one biphenyl furnace to form a biphenyl adding unit; air supply pipes and air return pipes used for connecting the spinning boxes in the biphenyl adding units are arranged on the biphenyl adding units; the air supply pipes of the two adjacent biphenyl adding units communicate with each other; the air return pipes of the two adjacent biphenyl adding units communicate with each other as well; the biphenyl preheating furnace is connected on the biphenyl furnaces through an air adding pipe; and exhaust pipes on the biphenyl furnaces and an air release pipe on the biphenyl preheating furnace are connected to communicate with the waste biphenyl recovery furnace. According to the biphenyl thermal adding system, the biphenyl furnaces with the same level communicate with each other through a series of pipelines which communicate with each other, and besides, the previous stage of biphenyl furnaces can be charged through the biphenyl furnace capable of achieving preheating, so that the safety is guaranteed while the temperature and pressure are guaranteed, the biphenyl adding time is saved, and the working efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of biphenyl adding devices on textile equipment, in particular to a biphenyl thermal adding system. Background technique [0002] During textile processing, biphenyl is heated to above 258°C to vaporize to form biphenyl vapor, and then the biphenyl vapor is used for heating. Considering environmental protection and safe production, biphenyl is used in the production of chemical fiber and spunbonded non-woven fabrics by heating and vaporizing. In the polyester filament production process, the biphenyl heating method is used to heat the melt filter device, melt distribution pipe, box system and other equipment. It usually takes 22-24 hours to heat the biphenyl to the vaporization temperature. Under normal circumstances, the temperature of the biphenyl boiler is vaporized above 258°C, and the biphenyl steam rises with the pipeline to supply the heating points of each equipment. During the continuous heating and vaporiz...
