Problems solved by technology

The existing devices and methods for desalinating seawater by distillation have the following disadvantages: the one is that the fluid circulation links in each device are driven by pumps (comprising vacuum pumps) for each effect, which needs to consume electric energy; Seawater takes away a lot of heat energy, causing energy loss; the third is to discharge a large amount of cooling water (only partly used for desalination), that is, the heat removal section takes

Embodiment Construction

[0015] The invention discloses a low-energy-consumption through-flow automatic vacuum seawater desalination device and method, which is a joint process of desalinating seawater, producing salt and brine by using a multi-effect distillation method. So a device such as figure 1 , figure 2 As shown, the seawater pump 1 is connected to the seawater tower 2 through the pipeline, the seawater tower is connected to the degassing tank 3, and the degassing tank 3 is respectively connected to the multi-effect tanks 5, 6, 7, single decalcification softening tank 4, low-pressure boiler 8, replacement Heater 22 and condenser 15, its heat exchangers 22, 23, 24, 25, 26, 27, 28 etc. are connected in series, and heat exchanger 28 is connected to seawater tower 2 again, and its condensers 15, 16, 17, 18 , 19, 20, and 21 are also multiple in series, and the condenser is also connected to the seawater tower 2. The multi-effect tanks 5, 6, and 7 are one-effect, two-effect...N-effect, and each mu...

Abstract

A through-flow vacuum seawater desalination plant and method are disclosed. Seawater pump is communicated with seawater tower by pipeline, seawater tower is connected with degassing tank, which is communicated with multi-effect tank, single decalcification softening tank, boiler and heat exchanger, multi-effect tanks are connected serially, which are communicated with condenser, condenser is communicated with gas-liquid separator, condenser is connected with gas-liquid separator or heat exchanger, and multi-effect tank is connected with concentrating tank. The process is carried out by vacuum supplying from multi-effect tank, pre-dipping fresh water outlets in fresh water pool, locating gas extraction opening at the top with level 10 meters above fresh water pool, shutting vacuum pump after vacuum supplying, opening softened water outlet valve with single decalcification, entering softened water into 1-N effect, flowing it into concentrated tank, reaching level of concentrated tank to certain position, operating concentrated tank and evaporating.

Description

technical field [0001] The invention relates to seawater desalination technology, in particular to a low-energy consumption through-flow automatic vacuum seawater desalination device and a treatment method. Background technique [0002] People have created a variety of methods for desalination of seawater, but there are mainly two types that are actually used at present. One is distillation, the other is membrane treatment, and the dominant one is distillation. The existing devices and methods for desalinating seawater by distillation have the following disadvantages: the one is that the fluid circulation links in each device are driven by pumps (comprising vacuum pumps) for each effect, which needs to consume electric energy; Seawater takes away a lot of heat energy, causing energy loss; the third is to discharge a large amount of cooling water (only partly used for desalination), that is, the heat removal section takes away more heat energy; the fo...
