What are the risks associated with the operation of carbon steel spiral plate heat exchangers with i

The medium carrying solid impurities (such as sediment, metal oxide scale, welding slag, crystalline particles, fiber suspension, etc.) into the carbon steel spiral plate heat exchanger channel can bring a series of risks such as wear, blockage, corrosion, structural deformation, and heat transfer failure. According to GB/T 28712 "Spiral Plate Heat Exchanger" and relevant specifications for pressu

What are the characteristics of vertical polishing storage tanks

1、 Structural characteristics 1. Vertical cylindrical structure, with an elliptical/butterfly shaped head on the upper part and optional butterfly or conical heads on the lower part; Leg or skirt support, making full use of vertical space, occupying a small area, and facilitating the centralized arrangement of multiple units in the tank area.

What should be paid attention to when using a deodorization tower in daily life

1、 Normal operation process parameter control (daily production) 1. Vacuum degree (deodorization lifeline) Absolute pressure stability control ≤ 3-4 mbar; Vacuum fluctuations can directly cause incomplete deodorization, oil discoloration, and lingering aftertaste. Check the steam jet pump and circulating cooling water temperature. If the cooling water temperature is too high, it wil

What is the working principle of a horizontal carbon steel storage tank

1、 Basic Definition Horizontal carbon steel storage tanks belong to atmospheric and low-pressure static equipment. The cylinder is horizontally arranged and made of carbon steel (mainly Q245R and Q345R). They are mainly used for storing liquid media (oil products, chemical raw materials, sewage, solvents, etc.), and the design pressure is mostly atmospheric or slightly internal pressure (ge

What is the main function of the outer coil stainless steel tower

1、 Core functional role 1. Heating, cooling, and correct temperature control of materials inside the tower (most importantly) Steam, thermal oil, and hot water (heating) are introduced into the coil; Cooling water and frozen salt water (cooling) transfer heat to internal materials through coils → tower walls, achieving heating, cooling, and constant temperature maintenance, adapting to exo

What are the characteristics of a coil reactor

Coil reaction vessels are divided into two categories: Built in coil (immersion coil inside the kettle) Outer half tube coil (welded semi-circular tube on the outside of the cylinder, commonly known as outer coil) Core function: Introduce steam, thermal oil, cooling water, and frozen salt water to achieve heating/cooling, replacing traditional jacketed reactors.
