Embodiment

[0040] Such as Figure 1~3 As shown, a vertical evaporator, the evaporator includes a heat exchange element, an expansion joint ⑤ and a shell ②, the heat exchange element in the evaporator is a pillow heat transfer element, and the pillow heat transfer element consists of multiple pairs The plate pair bundle composed of heat exchange plate pairs ①, and the fixture ④ that controls the distance between each heat exchange plate pair. The joint is usually set at the lower end of the heat exchange plate bundle. It is an elastic compensation element that can freely expand and contract, and can effectively compensate for axial deformation. When the bundle of heat exchange plates and the shell are deformed inconsistently due to temperature difference and pressure, it can absorb the deformation energy and automatically adjust the stress in the bundle of shells and heat exchange plates. The heat exchange plate pair is composed of two metal plates through multi-point welding to form a p...

Abstract

The invention relates to a vertical type evaporator. A heat exchanger element in the evaporator is a pillow type heat transfer element; the pillow type heat transfer element comprises a plate pair beam and fixed parts, wherein the plate pair beam is formed by a plurality of pairs of heat exchanger plate pairs, the fixed parts are used for controlling the spacing between the heat exchanger plate pairs, and the heat exchanger plate pairs are plate cavity components which are formed by multiple-spot welding of two metal plates and are used for heat exchanger fluid to flow, so as to form shell cavities between the heat exchanger plate pairs as well as between the heat exchanger plate pairs and a shell of the evaporator; to-be-evaporated fluid flows in plate cavities, and hot fluid flows in the shell cavities, so as to perform heat transfer. Compared with the prior art, the vertical type evaporator has the advantages of flexibility in structural adjustment, high heat transfer efficiency, low cost, convenience in cleaning and the like.

Description

technical field [0001] The invention relates to a vertical evaporator, in particular to a novel high-efficiency vertical evaporator. Background technique [0002] During the evaporation process, both cold and hot fluids undergo phase changes, and the solution to be evaporated has the characteristics of easy crystallization, scaling, foaming, large viscosity changes, corrosiveness, and boiling point changes during the evaporation process, so the evaporator form The selection and design process requires careful consideration of these factors. [0003] An important factor in judging the performance of an evaporator is the size of the heat exchange area per unit volume. The larger the heat exchange area per unit volume, the greater the processing capacity of the evaporator. A very important means. In order to strengthen fluid disturbance and promote convective heat transfer, the tiny pits on the boiling surface of the evaporator are most likely to produce vaporization cores. T...
