Ultrafiltration and silicon removal equipment for steam generator separation liquid

Abstract

The invention discloses a steam generator separation liquid ultrafiltration silicon removal equipment, which relates to the technical field of water treatment, comprising a base and a processing assembly arranged above the base, the processing assembly includes a processing tank, the two ends of the processing tank are connected to the base Side brackets are fixedly installed between the seats, and the top of the processing tank is set in a wide-mouth shape. The present invention utilizes the set primary filter press mechanism and the secondary filter press mechanism to carry out preliminary and further press filter treatment on the sediment; it can use the spiral extrusion strands to cooperate with the bottom end of the cone to realize the extrusion effect, and utilize the set filtrate At the same time, the screw extruding twisted sheet conveys the sediment after the preliminary filtration to the filter disc, and at the same time, the two pressure rollers are set to rotate with the shaft column, The rotating pressure roller is used to cooperate with the filter disc to achieve further pressure filtration treatment of the sediment, which facilitates the subsequent ultrafiltration treatment of the filtrate and avoids some colloidal silicon remaining in the sediment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a device for removing silicon by ultrafiltration of separated liquid of a steam generator. Background technique [0002] It has become an effective measure to recycle oilfield sewage into steam generators to alleviate the shortage of clean water resources in the oilfield injection and production process. The separation liquid obtained after the oilfield sewage is treated by the steam generator is called the separation liquid of the steam generator. A large amount of silicate exists in the separation liquid in the form of ions or colloids, and the separation liquid of the steam generator is directly used for steam injection. Generator, these silicon compounds in the separation liquid of the steam generator form dense and hard silicon scale, which is difficult to clean on the one hand, and will have a serious impact on the heat transfer efficiency and safe operation of the ...

Problems solved by technology

[0004] But the above-mentioned invention has the following shortcomings: the reaction stock solution of the above-mentioned patent cannot be directly mixed evenly during the addition process, and the reaction efficiency is low and the silicon removal efficiency is not high; Refined treatment, the effect of traditional single press filtration is poor, it is easy to cause more colloidal silicon to remain in the sediment, which cannot be separated and removed, and then affects the overall silicon removal effect, so there are certain limitations
