Titanium alloy disc type cooling tube motor union connector fresh water extractor

Abstract

The invention belongs to a special machine for extracting fresh water from seawater, and discloses a titanium alloy disc type cooling tube motor union connector fresh water extractor which comprises a seawater pretreatment tank, a pretreatment seawater sucking tube, a start sucking tube, a high-pressure start pump, a pipeline tee joint, a reverse osmosis membrane and a union pressure exchange pressurizer pump; as improvement, a pressurizing union connector comprises a volute outlet union check ring, conversion high-pressure union outer threads and a volute union outer ring; a volute outlet sealing spherical surface is arranged on the volute outlet union check ring; a conversion high-pressure sealing concave conical surface is arranged on the conversion high-pressure union outer threads; an outer-ring step surface and outer-ring inner threads are arranged on the volute union outer ring; the volute outlet union check ring is limited by the outer-ring step surface; the outer-ring inner thread is matched with the conversion high-pressure union outer threads to achieve hard sealing between the volute outlet sealing spherical surface and the conversion high-pressure sealing concave conical surface, and thus a pressurizing union connector can be formed. The union connection structure is capable of sealing and fixing a distorted pipeline and is compact in structure and remarkable in energy conservation effect.

Description

technical field [0001] The invention belongs to a special machine for extracting fresh water from seawater, in particular to a machine for extracting fresh water with a titanium alloy disc-type cooling pipe motor with a nonon joint added to a reverse osmosis seawater desalination system. Background technique [0002] With the advancement of science and technology, the population is increasing day by day, and people's desire to develop into the ocean is becoming stronger and stronger. Seawater desalination treatment is becoming more and more popular, and the energy consumption cost of seawater desalination has received special attention. Early seawater desalination used distillation, such as multi-stage flash technology, with an energy consumption of 9.0kWh / m3, and was usually only built in areas with low energy prices, such as Middle East oil countries, or areas where waste heat was available. In the 1970s, reverse osmosis seawater desalination technology was put into use an...
