Constant-temperature conveying pipeline device with function of preventing chemical material liquid from precipitation

Abstract

Disclosed is a constant-temperature conveying pipeline device with the function of preventing chemical material liquid from precipitation. The constant-temperature conveying pipeline device with the function of preventing chemical material liquid from precipitation comprises a stainless steel outer pipe, spiral heat conducting ribs, a metal heat exchange inner pipe, flow turbulence protrusions and flow turbulence columns. A circulation cavity is formed inside the metal heat exchange inner pipe. A plurality of flow turbulence protrusions are formed in the inner wall of the metal heat exchange inner pipe in an integrated casting mode, a flow turbulence groove is formed between every two adjacent flow turbulence protrusions, and a plurality of flow turbulence columns are arranged inside the metal heat exchange inner pipe at equal intervals. The stainless steel outer pipe sleeves the metal heat exchange inner pipe, a water-bath heating cavity is defined between the stainless steel outer pipe and the metal heat exchange inner pipe, and the stainless steel outer pipe and the metal heat exchange inner pipe are connected through the spiral heat conducting ribs. The mixing sufficiency of chemical material liquid is enhanced, the conveying efficiency and the conveying effect of chemical material liquid are improved, material liquid is prevented from precipitation and is sufficiently mixed. The metal heat exchange inner pipe is uniformly heated, and constant-temperature heating and conveying of chemical material liquid are guaranteed. The heat insulation effect is good, and the constant-temperature conveying pipeline device with the function of preventing chemical material liquid from precipitation is suitable for constant-temperature conveying of chemical material liquid.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a constant temperature conveying pipeline device for preventing deposition of chemical material liquid. Background technique [0002] In the process of chemical production, it is necessary to transport the chemical material liquid to facilitate the next production process. For the transportation of various material liquids or slurries, it is necessary to ensure a constant temperature and carry out the transportation. The existing delivery pipe is difficult to Its heat treatment only wraps the insulation material on the outer wall of the pipeline to reduce heat loss, and cannot guarantee the effective transportation of materials. The chemical material liquid will block the pipeline after cooling, solidification and viscous, and during the transportation process, part of the material liquid components in the chemical material liquid will be lost. Precipitation occurs or ...

[0002] In the process of chemical production, it is necessary to transport the chemical material liquid to facilitate the next production process. For the transportation of various material liquids or slurries, it is necessary to ensure a constant temperature and carry out the transportation. The existing delivery pipe is difficult to Its heat treatment only wraps the insulation material on the outer wall of the pipeline to reduce heat loss, and cannot guarantee the effective transportation of materials. The chemical material liquid will block the pipeline after cooling, solidification and viscous, and during the transportation process, part of the material liquid components in the chemical material liquid will be lost. Precipitation occurs or deposits on the inner wall of the pipeline, which can lead to pipeline blockage in severe cases, requiring regular cleaning of the pipeline and high maintenance costs
