Carbon Dioxide Storage Tank

1 Overview

The low-temperature liquid carbon dioxide storage tank is a double-walled container consisting of an inner and an outer vessel. It features vacuum powder insulation and is available in both vertical and horizontal configurations. The inner vessel is made of 16MnDR material, while the outer vessel material can be selected as Q235-B or 16MnR based on the user's location. The annular space between the inner and outer vessels is filled with insulating material, Pearlite sand, and then vacuumed. (Available in vertical and horizontal types)

2 Uses

Storage: Liquid Carbon Dioxide (LCO2)

3 Insulation Performance

Insulation materials are filled with pearlescent sand in the heated state for the sandwich layer, followed by vacuum extraction. The standard vacuum degree after the sandwich layer is sealed is:

Effective Volume: ≤ 10m³ with vacuum ≤ 2Pa, > 10m³ ≤ 50m³ with vacuum ≤ 3Pa, > 50m³ ≤ 100m³ with vacuum ≤ 5Pa. Achieved with exquisite technology, unique filling process, and quality assurance commitment for optimal thermal insulation effect.

4 Security Technical Features

Low-temperature liquid carbon dioxide storage tanks utilize a "combined safety system valve" that employs two safety valves working simultaneously. During regular safety valve inspections, one side can be closed while the other continues to operate, ensuring the safe operation of the tank.

5 Operating Systems

The tank container is equipped with a pressure gauge, a differential pressure level gauge, and a level reference chart at the top, allowing for real-time monitoring of the storage volume and pressure changes. This facilitates operations during filling and draining.

6 Inspection System

The bottom of the tank is equipped with a dedicated vacuum detection system for the tank, including vacuum gauges and valves. The vacuum level in the tank can be periodically or immediately checked using a vacuum gauge to ensure the safe operation of the tank.

Liquid Oxygen Storage Tank

Overview

This series of low-temperature storage tanks are double-layer fixed vacuum powder insulation tanks (storage bins). The inner tank is made of stainless steel (with 16MnDR for CO2 tanks), and the outer tank is made of Q235B or 16MnR. Surface anti-corrosion coating is achieved through sandblasting, sweeping, and spraying processes, while a two-component quick-curing liquid paint is also used.

Application Range and Features

Primarily used for low-temperature storage of liquefied oxygen, nitrogen, argon, and carbon dioxide, etc. One cubic meter of liquid can replace 130 gas cylinders. It can eliminate the daily transportation of gas cylinders, saving a significant amount of labor and material resources. Widely applied in industries with high gas consumption such as the gas industry, hospitals, and metal smelting, it is the best product for centralized gas supply. It features a long service life, compact structure, minimal land occupation, centralized control, and easy operation.
