Embodiment

[0018] Such as figure 1 Shown is a kind of reticular heating caustic soda concentration heating furnace of the present invention, described heating furnace 1 comprises furnace body 11, and the top of described furnace body 11 has water vapor outlet 12 and material inlet 13 respectively, and described furnace body The bottom of 11 has discharge opening 14.

[0019] Such as figure 2 As shown, the furnace body 11 is provided with a heating grid 15, and the heating grid 15 is composed of a plurality of horizontally laid square heating columns 151 criss-crossed. Sputtering occurs under the barrier of net 15, and the time for lye to fall to the bottom of furnace body 11 is slowed down during the splashing process. At the same time, heating column 151 is heated and evaporated; the bottom of said furnace body 11 is provided with an inclined surface 19. The discharge port 14 is set at the low point of the inclined surface 19, and the liquid caustic soda passes through the heating ne...

Abstract

The invention discloses a netted heating furnace for caustic lye of soda concentration. The heating furnace comprises a furnace body; the top of the furnace body is provided with a steam outlet and a material inlet respectively; the bottom of the furnace body is provided with a discharge port; a heating net is arranged in the furnace body; and the heating net comprises a plurality of horizontal square heating columns staggered vertically and horizontally. Compared with the prior art, the invention has the advantages that through the heating net arranged in the heating furnace, the caustic lye of soda is heated evaporated and concentrated while falls down under the action of gravity and splashes on the heating columns, so as to save time and labor, and increase work efficiency; and heating furnace does not need external power device to complete the concentration of caustic lye of soda..

Description

technical field [0001] The invention relates to the technical field of caustic soda production and processing, in particular to a reticular heating furnace for concentrating caustic soda liquid. Background technique [0002] Existing caustic soda production enterprises mostly adopt caustic soda solution with low concentrated concentration by burning in a large pot. After heating, the evaporation is accelerated, the concentration of caustic soda solution is increased, and then it is solidified by cooling. [0003] Existing manufacturers use a drum-type caustic soda concentration device to heat the drum-type furnace body. The drum body is inclined at a certain angle from the horizontal plane, and the water vapor is discharged from the feed port. The heater is located in the drum. Below the body, its disadvantages are: [0004] 1. The water vapor is discharged from the feed port, causing serious condensation and solidification of caustic soda at the feed port, which is easy to...
