Embodiment Construction

[0014] Such as figure 2 Shown is a schematic diagram of a two-stage condenser five-effect distillation seawater desalination device, which consists of working steam inlet 1, working steam condensate outlet 2, first-effect evaporator 3, concentrated seawater connecting pipe 4, condensed fresh water connecting pipe 5, two Effect evaporator 6, three-effect evaporator 7, four-effect evaporator 8, concentrated seawater discharge pump 9, fresh water discharge pump 10, secondary steam inlet condenser tube 11, first stage condenser 12, seawater inlet 13, seawater cooling The water discharge port 14, the non-condensable gas discharge port 15, the seawater inlet branch pipe 16, the five-effect evaporator 17, the second stage condenser 18 and the control system (not shown in the figure) etc. are composed. Based on the original low-temperature multi-effect distillation seawater desalination device, the original condenser is divided into the first-stage condenser and the second-stage cond...

Abstract

The invention relates to a multi-effect distillation seawater desalinating device of a multi-section type condenser, belonging to the technical field of seawater desalinization. The device comprises an evaporator, a condenser, a working steam inlet (1), a working steam condensate water outlet (2), a concentrated seawater connecting pipe (4), a condensed fresh water connecting pipe (5), a concentrated seawater draining pump (9), a fresh water draining pump (10), a secondary steam inlet condensing pipe (11), a seawater inlet (13), a cooling seawater draining port (14) and a seawater inlet branchpipe (16). The invention is characterized in that the condenser is divided into N sections from section 1 to section N, and seawater enters in the multi-section type condenser from the section N to the section 1 which are connected in series; on the basis of an original M-effect evaporator, an N-1-effect evaporator which corresponds to the N-section condenser is additionally arranged on the evaporator; secondary steam coming out of the original M-effect evaporator is divided into two paths and enters the 1-effect condenser and the M+1-effect evaporator in parallel, and so forth,, the secondary steam coming out of the M+N-1-effect evaporator enters the N-effect condenser finally. On the premise of not increasing the quantity of inlet seawater of unit water making quantity, the invention can increase the total temperature difference of the first evaporator and the last evaporator.

Description

(1) Technical field [0001] The invention relates to a multi-stage condenser multi-effect distillation seawater desalination device. It belongs to the technical field of seawater desalination. (2) Background technology [0002] With the continuous development of the economy and the improvement of people's living standards, people's demand for fresh water is increasing, and the requirements for water quality are getting higher and higher. However, the shortage and uneven distribution of water resources make the originally tense supply and demand of water resources The contradiction is more acute. The low-temperature multi-effect distillation seawater desalination device in the seawater desalination technology uses thermal energy to produce water with high quality and broad development prospects. [0003] The multi-effect distillation seawater desalination device uses a certain amount of working steam to drive through multiple evaporation and condensation, so as to obtain con...
