Problems solved by technology

However, because the spray evaporator and condenser are connected by separate pipes, this causes problems such as low heat exchange efficiency.
In the prior art, although there are also devices that combine evaporators and condensers to overcome the aforementioned problems, their heat exchange efficiency is still not ideal, and when the combined device of evaporators and condensers is used for sewage treatment, its surface will also scale

Embodiment

[0035] like Figure 1~Figure 3 Shown: A combined evaporator and condenser, including a rotating disk evaporator 1 and a tube bundle condenser 5, which are composed of a plurality of rotating disks arranged in parallel and spaced to play an evaporation role driven by a rotating shaft 2 . The tube bundle 7 of the tube bundle condenser 5 is arranged in a detour in the interval of the rotating disk, and along the outer surface of the tube bundle 7, a plurality of annular protrusions 9 are arranged side by side. The contact surface between the outer surface of the annular protrusion 9 and the tube bundle 7 transitions smoothly. The distance between the rotating disk and the annular projection 9 is between 1 mm and 10 mm, and in this embodiment, it is selected as 2 mm. The inner wall of the tube bundle 7 is provided with baffles 8 spaced up and down.

[0036] During installation and use, the liquid level 3 of the evaporating liquid is located at the lower half of the rotating disk...

Abstract

The invention provides a combined evaporator and condenser and a control method thereof. The combined evaporator and condenser comprises a rotary table evaporator which consists of rotary tables arranged in parallel at intervals on a rotary shaft to evaporate and a bundle condenser. The bundle of the bundle condenser is circuitously arranged in intervals of the rotary tables, and a plurality of annular bumps are arranged in parallel on the outer surface of the bundle. The combined evaporator and condenser provided by the invention has the prominent advantage of intensifying the heat exchange efficiency of the bundle of the condenser and a liquid by maintaining the flow velocity of the liquid on the surface of the bundle of the condenser at a high speed.

Description

technical field [0001] The invention relates to a process equipment for heat exchange of evaporation and condensation in the process flow of water treatment field and chemical industry and refrigeration industry, in particular to a combined evaporator and condenser and its control method. Background technique [0002] In the water treatment field and in the process flow of the chemical industry and refrigeration industry, there are two heat transfer processes of evaporation and condensation at the same time. At present, the process equipment usually divides the evaporator and condenser into two independent working parts, and connects them with process pipelines. Especially in the pressure-vapor distillation method used in the field of water treatment, the circulation process adopted is to pump the waste water into the top of the spray evaporator through a liquid pump, and the waste water absorbs heat and evaporates during the process of falling from the top by gravity. The ...
