AI Technical Summary
Technical Problem
During the pyrolysis and gasification process of dried sludge, the temperature of the air after preheating is uneven due to the influence of gravity or flow inertia, resulting in a reduction in the preheating effect.
Method used
Design a heat exchanger structure including a shell, fixed tube sheet, baffle, open frame, mixing chamber and spiral guide vanes, to improve preheating uniformity by mixing and colliding air in the mixing chamber.
Benefits of technology
This results in more uniform air preheating, improving preheating effect and heat exchange efficiency.

Abstract
The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger applied to pyrolysis gasification, which is characterized in that a partition plate is fixedly connected to the inner upper end of a shell, a first heat exchange chamber and a second heat exchange chamber are arranged between the partition plate and two fixed tube plates, an open frame is connected to the inner upper end of the first heat exchange chamber, and strip-shaped holes are formed in two sides of the bottom end of the open frame; the two sides of the upper end of the open frame are both connected with perforated plates, a mixing chamber is arranged between each perforated plate and the open frame, and each mixing chamber is communicated with the corresponding strip-shaped hole. Air subjected to heat exchange enters the first heat exchange chamber through the gap opening, flows upwards and is in contact with the open frame, and the air enters the mixing chamber through the strip-shaped holes and is further mixed in the mixing chamber, so that the air is preheated more uniformly, the air preheating effect is improved, meanwhile, the air entering the mixing chamber collides with the spiral guide vanes, and the heat exchange efficiency is improved. The mixing effect is enhanced.
