Embodiment Construction

[0036] Below, with reference to accompanying drawing and embodiment the novel multi-effect evaporator of the present invention is described in detail:

[0037] Such as Figure 1-7 As shown, a new type of multi-effect evaporation device includes an upper cover 1 and a lower cover 2, and the upper cover 1 and the lower cover 2 are respectively installed on the upper and lower ends of the No. I sleeve 6-1 located in the center. The No. I sleeve 6 -1, No. II sleeve 6-2, No. III sleeve 6-3, No. IV sleeve 6-4, and No. V sleeve 6-5 are arranged concentrically from the inside to the outside and at a certain distance to form a sleeve structure6.

[0038] Among them, the No. 1 sleeve 6-1 located in the center forms a first-effect material liquid chamber 9 with the upper cover 1 and the lower cover 2, and the cavities formed between the other sleeves are the second-effect heating chamber 10, Second-effect feed liquid chamber 11 , three-effect heating chamber 12 and three-effect feed li...

Abstract

The invention discloses a novel multiple-effect evaporation device which comprises an upper cover, a lower cover, a steam inlet, a condenser and a feed pump, wherein the upper cover and the lower cover are arranged at the upper end and the lower end of the center of a sleeve structure respectively so as to form a flange structure; multiple sleeves are concentrically and sequentially arranged from interior to exterior so as to form the sleeve structure; a single-effect feed liquid chamber, a double-effect heating chamber, a double-effect feed liquid chamber, a triple-effect heating chamber and a triple-effect feed liquid chamber are respectively formed; two adjacent feed liquid chambers are communicated with each other through a U-shaped pipe. A triple-effect evaporation mode is formed by adopting the multilayer sleeves, and the device is simple in structure and convenient to operate. Compared with a traditional process, the process of the novel multiple-effect evaporation device has the advantages that the occupied area is reduced, the heat transfer and evaporation efficiency is improved, the heat loss is reduced, various corrosive solutions such as strong acid and strong base, and high-viscosity solutions are concentrated by adopting a corrosion-resistant coating, the application range of the device is widened, and the service life is prolonged.

Description

technical field [0001] The invention belongs to an evaporation device, in particular to a novel multi-effect evaporation device. Background technique [0002] Wastewater evaporator refers to a type of special-purpose evaporator used for wastewater treatment. Sewage and wastewater come in many varieties with varying characteristics and can be treated in a variety of ways. Some wastewater, because of its high concentration of salt, cannot be treated by biochemical treatment or other methods, and can only be treated by evaporation and desalination; some wastewater can be concentrated by evaporation to turn waste into treasure. The wastewater evaporator adopts multi-effect evaporation process, multi-effect evaporation + drying process or multi-effect evaporation + crystallization process to treat sewage or wastewater, so that the evaporated water meets the national discharge standards. According to the characteristics of saline wastewater, the wastewater evaporator can be a mu...
