BIO GAS UPGRADING EQUIPMENT

摘要

PURPOSE: A bio-gas purifier is provided to use a bio-gas dissolving unit, a pressure pump and a separation tank, thereby purifying a large amount of bio-gas only with a small simple device. CONSTITUTION: A bio-gas purifier comprises: a bio-gas storage tank(100), a bio-gas dissolving unit(200), a pressure pump(300), a separation tank(400), a flush tank(500) and a control unit(600). The bio-gas dissolving unit makes the bio-gas to micro-bubbles, and dissolves the micro-bubbles in water. The pressure pump pressures the water dissolved with the bio-gas. The separation tank is equipped with a spray means, a connecting path(420), a pressure controller and an exhaust path(440). The spray means is connected to the pressure pump, and sprays the water dissolved with the bio-gas. The connecting path exhausts the gas sprayed by the spray means. The inner gas pressure(P2) of the separation tank is formed smaller than the spray pressure(P1) of the pressured water dissolved with the bio-gas by the pressure controller. The exhaust path is formed to exhaust the water dissolved with the bio-gas.
