Steam-heating reaction kettle heat exchange device with perforated spiral guide plate

Abstract

The invention discloses a steam-heating reaction kettle heat exchange device with a perforated spiral guide plate. The steam-heated reaction kettle heat exchange device comprises a reaction kettle barrel, and a reaction kettle jacket barrel sleeves the outside of the reaction kettle barrel; the spiral guide plate is arranged between the reaction kettle jacket barrel and the reaction kettle barrel;a series of through holes are formed at the inner side of the helical surface of the spiral guide plate and along the trend of the helical surface; a steam inlet is formed in the side wall of the reaction kettle jacket barrel, and a condensate outlet is formed in the bottom of the reaction kettle jacket barrel; a reactant production hole is formed in the top of the reaction kettle barrel, and a material inlet is formed in the bottom of the reaction kettle barrel. According to the steam-heated reaction kettle heat exchange device with the perforated spiral guide plate, part of steam is ejectedto a next layer of flow channel from the small holes in the spiral guide plate so as to impact a liquid film of the next layer of flow channel, so that a liquid film on the wall surface of the reaction kettle barrel of the next layer of flow channel becomes turbulent flow from laminar flow, and the thickness of the laminar flow liquid film is reduced or even the liquid film is torn; therefore, the heat transfer coefficient and the utilization efficiency of the latent heat of steam are increased.

Description

technical field [0001] The invention relates to the technical field of chemical process reactor heat exchange, in particular to a steam-heated reactor heat exchange device with a spiral deflector plate with holes. Background technique [0002] Reactors are widely used in the chemical industry, and their heating methods include electric heating, steam heating, heat transfer oil heating, far-infrared heating, and inner (outer) coil heating lamps. The principle of the steam heating reactor is to pass the boiler steam into the jacket of the reactor, transfer the heat of the steam into the reactor, and make the materials in the reactor absorb heat and react. The steam heating method is latent heat release of steam, which has the characteristics of rapid heating, simple and reliable equipment, and is widely used in industrial production. The expansion of industrial production scale and the need to save energy have put forward higher requirements for the heat transfer performance ...

AI Technical Summary

Problems solved by technology

Reactors used in industrial production are generally larger in size, the steam heat transfer process is longer, the steam flow rate is very low, the formed laminar liquid film is thicker, and the thermal resistance is larger.
