Brief introduction of coalbed methane filter:
(1) Clarification of coal bed gas filter technology ① Design and process conditions Quickly open a single filter separator with a capacity of 175,000 cubic meters.
Efficiency of separating solid and liquid particles:
99.8% when solid particles ≥5μm: 99.6% when droplets ≥10μm: and do not show liquid entrainment, entrainment, suction, secondary crushing phenomenon The process conditions of impurities, after purification treatment by high-efficiency gas filters, reach a filtration accuracy of less than 5 μm (or filtration efficiency n≥9.5%), and the initial resistance of the filter △ P≤20kPa
③ The principle of the filter and its filter tube technology connects the coal bed gas dust filter to the pipeline of the gathering and transportation system. The quick-opening blind plate device is located on the upper end of the separator shell. The lower device has a magnetic rod that absorbs the iron particles of coal bed gas through magnetic force. A small hole is opened in the partition. A polyester filter tube is installed on the small hole. Ester filter tube, the filter tube is filled with GLT fiber type filter element, which can adsorb the dust and liquid particles in coal bed gas, so as to achieve the effect of filtering iron filings, liquid and dust particles. GLT fiber filter element has the advantages of high dust removal efficiency, small resistance loss, high temperature resistance, corrosion resistance, etc. It is especially suitable for precision filtering places, and the purification level can reach fine.
Applicable medium: natural gas, oil field gas, coal gas and other gases.
Filter material; polyester fiber dust removal efficiency: 95-99.8%
Gas activity direction: filtration accuracy and filter resistance from the inside to the outside:
When the solid dust particles are larger than 5μm, the dust removal efficiency is 998%
When the liquid particles are larger than 10 μm, the dust removal efficiency is 99.6%
