Grille device for seawater desalination by using thermal distillation method

Abstract

The invention relates to the technical field of seawater desalination accessory devices, in particular to a grille device for seawater desalination by using a thermal distillation method. The grille device can automatically clean intercepted impurity particles and improve treatment continuity. The grille device comprises a platform, an annular screen and a water receiving tank, wherein the surface of the screen is in a sieve shape, the water receiving tank is installed on the top of the platform, the screen is located above the water receiving tank, the bottom end of the water receiving tank communicates with a water outlet pipe, a water inlet pipe is arranged on the left side of the screen, the top of the platform is fixedly connected with two sets of inclined rods, the two sets of inclined rods are rotatably provided with a driving shaft, a first motor is arranged at the left end of the driving shaft, a plurality of connecting rods connected with the inner left end and the inner right end of the screen are fixedly connected to the driving shaft, a left hydraulic cylinder and a right hydraulic cylinder are fixedly connected to the top of the platform, a left support and a right support are fixedly connected to the top ends of the left hydraulic cylinder and the right hydraulic cylinder correspondingly, a left rotating shaft is rotatably arranged on the left support, and a right rotating shaft is rotatably arranged on the right support.

Description

technical field [0001] The invention relates to the technical field of seawater desalination attachments, in particular to a grille device for desalination of seawater using thermal distillation. Background technique [0002] Seawater desalination is a freshwater incremental technology. The more commonly used seawater desalination process is low-temperature multiple-effect distillation technology. This technology desalinates seawater below 70°C, so it can effectively avoid the condensation of raw water evaporated inside the device on the heat exchange wall. scale, the equipment is safer and more reliable due to low temperature operation. The feature of this technology is that a series of horizontal tube falling film evaporators are connected in series, and a certain amount of steam input is used to undergo multiple evaporation and condensation to obtain distilled water. The process is roughly seawater→seawater lift pump→grid treatment→flocculation treatment→clean water tank...

Problems solved by technology

[0003] However, in the grid processing in the prior art, the impurity particles intercepted by the grid cannot be cleaned automatically, and it needs to be stopped for processing regularly, resulting in interruption of continuity
