Embodiment Construction

[0022] Such as figure 1 As shown, the liquid inlet 1 is installed at the bottom of the heater 5 and is connected with the lower tube box 2, and the particle distributor 3 is installed at about 100 mm above the lower tube box 2. This position is most beneficial for the particle-liquid mixture to have enough The distance between the particles enters the particle distributor, so that the particles are evenly distributed, and the fluid velocity is also reasonably divided, so that it enters the tube array 6 installed between the upper tube sheet 7 and the lower tube sheet 4 at a roughly uniform speed. After the fluid in the liquid inlet 1 passes through the particle distributor 3, the fluid with a faster flow rate in the middle is evenly dispersed into the surrounding tubes. The lower tube box 2 and the lower tube plate 4 are connected by flanges, and the lower tube plate 4 and the upper tube plate 7 Weld the tubes 6 in the middle, and it is better to polish the inside of the tubes...

Abstract

The invention discloses a full-automatic descaling multi-effect evaporator, which comprises a heater and an evaporation chamber, wherein a granule distributor which can make fluid be distributed to tube nests of the heater uniformly is arranged at the bottom of the heater; and a granule separator is also arranged between the heater and the evaporation chamber. Due to the adoption of the technical scheme, the full-automatic descaling multi-effect evaporator has the advantages that a descaling process can be simplified, heat transfer is enhanced, and a heat transfer coefficient is increased, so that the evaporator can clean and remove scales online to realize continuous production. According to the optimized technical scheme, an intensifier ring is arranged in the granule separator, and a granule separation chamber and a granule storage chamber are also formed in the granule separator, so that liquid forms a vortex which rotates at high speed when passing through the cylindrical granule separation chamber under the action of centrifugal force formed by the intensifier ring to do circular rotary motion, so that granular solids are separated from the liquid quickly.

Description

technical field [0001] The invention relates to the technical field of removing dirt on the inner wall of tubes of evaporator heaters, in particular to an evaporator device using solid particles for automatic descaling. technical background [0002] Evaporator scaling is a common problem in the process of evaporation and concentration. Evaporator scaling is mainly divided into the following categories: hard scaling, water-soluble scaling, fiber and saponified scaling, aluminum silicate scaling, scaling phenomenon It mainly occurs in the heater tubes. The scale layer greatly weakens the heat transfer, reduces the heat transfer coefficient, increases energy consumption, affects the output and quality of the product, and in serious cases will affect the production or even cause the shutdown. The existing method for removing dirt is mainly to use artificial, mechanical or chemical methods to clean after parking and dismantling, thereby causing production reduction and loss. [...
