Abstract

A low flow velocity reinforced natural reversed cycle automatic cleaning type evaporation plant is characterized in that, a boiling house with big cross section and depth can make natural cyclic driving force reinforce in low flow velocity, which consists of a central tube boiling house and a flaring boiling house; a plastic screw with swirl flow reinforced torque arrangement is mounted in tube, can be cleaned automatically under low flow speed, and the requirement for natural cyclic flow speed and driving force is low. The device does not need a forced circulation pump and can be used in different evaporation production.

Description

technical field [0001] The patent of the present invention relates to a low flow rate enhanced natural reverse cycle automatic cleaning evaporation device. This device can be widely used in the evaporation production of sugar, salt, caustic soda, chemical industry (such as anhydrous sodium sulfate, soda sulfide), papermaking, pharmaceuticals, metallurgy (such as alumina production) and many other industries. Background technique [0002] The evaporators currently in use generally have the problem of rapid and thick scaling on the heating surface, and the need for periodic parking and cleaning. The production capacity is severely reduced and the steam consumption is significantly increased. For this reason, a forced circulation pump with high energy consumption is used to speed up the circulation flow rate in the heating tube. However, periodic water cleaning is still required, but the cleaning cycle is prolonged. Contents of the invention [0003] The patent of this inve...
