The market application and functions of the gas cylinder cleaning machine

The gas cylinder cleaning machine is a highly efficient and automated device specifically designed for cleaning various industrial gas cylinders, liquefied petroleum gas (LPG) cylinders, seamless gas cylinders, etc. It is a key piece of equipment in the end-of-life gas cylinder recycling and processing assembly line and gas cylinder inspection station, ensuring the internal cleanliness and safety of gas cylinders before inspection, refurbishment or recycling.

I. Market Application

The market demand for gas cylinder cleaning machines mainly stems from two core links: regular inspection of gas cylinders and resource recycling of scrapped gas cylinders.

Gas Cylinder Testing Stations

Application description: According to national mandatory regulations, all types of high-pressure gas cylinders (such as industrial oxygen cylinders, acetylene cylinders, nitrogen cylinders, etc.) must be sent to professional institutions for inspection regularly (usually every 3 or 5 years). Only after passing the inspection can they continue to be used.

The necessity of cleaning: The interior of used gas cylinders will accumulate water vapor, rust, oil stains, chemical residues, odors, etc. Before conducting key steps such as internal inspection and water pressure testing, it must be thoroughly cleaned; otherwise, it will affect the accuracy of the inspection results and even cause contamination and damage to the inspection equipment.

Market-driven: The mandatory requirements of safety regulations are the main driving force of this market. Each region has authorized gas cylinder inspection stations, which are essential users of gas cylinder cleaning machines.

Application description: For scrapped gas cylinders that have reached their designed service life or failed inspection, environmentally friendly and safe resource recycling and treatment are required.

The necessity of cleaning: Scrapped gas cylinders, especially LPG cylinders, usually contain heavy oil residues, hydrogen sulfide, malodorous substances, etc. inside. Thorough cleaning must be carried out before subsequent processes such as milling the bottom and crushing. Otherwise:

Safety risk: Residual flammable substances may cause fire or explosion during subsequent processing.

Environmental pollution: During crushing, oil splashes everywhere, seriously polluting the equipment and the environment.

Resource value: Scrap steel with oil stains is of low quality grade and its selling price is greatly discounted. After cleaning, pure and high-quality scrap steel can be obtained.

Market-driven: The tightening of environmental protection policies and the development of the circular economy (the concept of "urban mines") are the main driving forces of this market. High-value recyclables require more efficient and thorough pretreatment cleaning.

Cylinder Manufacturing & Refurbishing Plants

Application description: In the pretreatment process before painting for manufacturing new bottles or refurbishing old ones, it is necessary to clean the bottle body to ensure the adhesion of the paint surface.

Ii. Function Description

The gas cylinder cleaning machine is a system integrating mechanics, electricity, hydraulics/pneumatics and chemistry. Its main functions can be summarized as follows:

Core function: Thoroughly remove physical and chemical contaminants inside the gas cylinder.

To achieve this core function, a typical automated cylinder cleaning machine usually has the following subsystems and working steps:

Loading and Conveying function (loading & Conveying)

The gas cylinders are sent to the cleaning station in an orderly and stable manner by means of roller conveyor lines, chain plate lines or robot automatic grasping, achieving continuous operation.

Clamping & Positioning function

The bottle mouth is precisely positioned and clamped by hydraulic or pneumatic chucks to ensure that the cleaning nozzle can be accurately and sealed into the bottle mouth, preventing high-pressure water leakage.

Washing function - Core function

High-pressure hot water rinsing: Use a high-pressure pump (usually with a pressure above 20-100 bar) to spray hot water into the bottle in a fan shape or through a rotating nozzle. Hot water can effectively melt and wash away oil stains.

Rotary spray system: The cleaning arm drives the nozzle to rotate and reciprocate 360 degrees inside the bottle, ensuring that every corner of the bottle is cleaned without any blind spots.

Automatic addition of cleaning agent: The system will add dedicated industrial cleaning agent or caustic alkali solution to the hot water in proportion, and through chemical action, saponify and decompose stubborn oil stains.

Rinsing function

Repeatedly rinse the gas cylinders that have been washed with the cleaning agent with high-pressure clean water to thoroughly remove the remaining cleaning agent and the dirt that has been stripped off, ensuring that the cylinders are clean and free of chemical residues.

Drying function

After cleaning and rinsing, a hot air purging system (usually composed of a fan and a heater) is used to dry the inside of the bottle, remove moisture, prevent rusting inside, and prepare for subsequent inspection or handling.

Water Circulation & Treatment Function

Key points for environmental protection and energy conservation: The equipment is equipped with a water storage tank, a filtration system, an oil-water separator and a heating system.

The wastewater after cleaning undergoes multi-stage filtration (such as vortex separation, magnetic separation, and bag filtration) to remove most solid particles and floating oil. Then it is heated and recycled, significantly reducing the consumption of fresh water and the amount of wastewater discharged.

Automated Control Function

The entire cleaning process (such as cleaning time, water temperature, amount of cleaning agent added, drying temperature, etc.) is fully automatically controlled by PLC (Programmable Logic Controller).

The operator only needs to select the cleaning program on the human-machine interface (HMI touch screen), and the equipment will automatically complete the entire process, ensuring stable and reliable cleaning quality and recording the operation data.

Summary

Description of characteristic dimensions

The market positioning serves the two essential markets of gas cylinder safety inspection and environmental protection recycling.

Core values: ensuring safety (inspection and subsequent processing), enhancing efficiency (automation), protecting the environment (emission reduction), and creating value (improving the quality of recycled steel).

The core technology is a comprehensive cleaning technology that combines high pressure, hot water, cleaning agents and multi-angle spray.

The development trend is towards a higher degree of automation and intelligence (such as visual recognition of bottle shapes), greater energy conservation and environmental protection (efficient water circulation and heat recovery systems), and modular design to meet the needs of different customers.

Cylinder cleaning machines are not merely simple cleaning tools; they are indispensable core equipment in the modern, large-scale, and compliant gas cylinder inspection and recycling industry.
