Stability and Characteristics of Coal Mine Underground Nitrogen Generators, Explosion-Proof Nitrogen Generators, and Carbon Molecular Sieve Nitrogen Generators
Utilizing multiple gas separation devices and programmable valve technologies, along with specialized design processes and domestic and international carbon molecular sieves, effectively enhances the equipment's nitrogen production capacity, air utilization rate, and long-term operational performance.
Coal mine underground nitrogen generators, explosion-proof nitrogen generators, and carbon molecular sieve nitrogen generators adopt flexible, mobile, and user-friendly designs.
Two mobility options: rail wheels or rubber tires, with two rail gauge designs of 600 or 900 (mm), meeting coal mine transportation requirements.
Multiple power specifications: 380V/3ph/50Hz, 660V/3ph/50Hz, 1140V/3ph/50Hz, adapting to coal mine power supply needs.

Surface Nitrogen Generators
Lecheng's surface fixed and surface mobile coal mine nitrogen generation equipment is suitable for mines with large mining areas, frequent fires, and short distances between surface and underground working faces.
Non-Equilibrium Pressure Equalization Energy-Saving Technology
The process flow directly reduces compressed air consumption.
The equipment employs a non-equilibrium pressure equalization process, which improves the lower pressure equalization position. During pressure equalization, the equalizing gas is drawn from the middle of the adsorption tower where adsorption has ended and introduced into the bottom of the adsorption tower where desorption has ended. This equalization follows the inverted pyramid gradient distribution of purity within the adsorption tower, thereby increasing recovery rates and carbon molecular sieve utilization, and changing the history where pressure swing adsorption could not produce high-purity (99.9995% N2) nitrogen.
Cylinder Compaction Technology
Effectively extends molecular sieve service life up to 10 years.
Features automatic compensation for molecular sieve loosening, keeping the molecular sieve consistently compacted, effectively extending its service life to 10 years, ensuring long-term equipment operation.
Molecular Sieve
Molecular sieves provide high cost-performance advantages for the equipment.
With nearly forty years of collaboration with domestic and international molecular sieve manufacturers,
Energy-saving products can be selected based on user gas usage processes and working conditions.
