Biogas pressurizing water-washing device

Abstract

A biogas pressurizing water-washing device comprises a gas incoming tank, an absorbing tower, a tower cap, a gas incoming pipe, a gas outgoing pipe, a water incoming pipe and a water outgoing pipe. The absorbing tower is fixed to the upper portion of the gas incoming tank, a filler supporting plate is arranged at the bottom of the absorbing tower, a through hole is formed in the filler supporting plate, a filler is arranged in an absorbing tower cavity, a liquid level meter is arranged on a tower body, the tower cap is fixed to the absorbing tower, a safety valve port is arranged at the top of the tower cap, one end of the gas incoming pipe goes into a gas incoming tank cavity while the other end of the same is connected with a gas supply device, and a pressure stabilizing valve, a gas flow meter and a gas incoming pipe one-way control valve are arranged in the middle of the gas incoming pipe; one end of the gas outgoing pipe is connected with the upper side portion of the tower cap while the other end of the same is connected with a gas storing device, a gas outgoing pipe depressurizing valve, a gas outgoing pipe ball valve and a gas outgoing pipe flow meter are arranged in the middle of the gas outgoing pipe, one end of the water incoming pipe is connected with the lower side face of the tower cap while the other end of the same is connected with a water supply mechanism which is matched with a water collection tank, one end of the water outgoing pipe is connected with the bottom of the gas incoming tank while the other end of the same extends into the water collection tank, and the filler is a ceramic step ring. By the biogas pressurizing water-washing device, water-washing efficiency and effect are improved, and completeness, safety and operability of the whole system are embodied.

Description

technical field [0001] The invention belongs to the technical field of biogas impurity removal and purification equipment, and in particular relates to a biogas pressurized water washing device. Background technique [0002] Biogas is a low-calorific-value biomass gas mainly composed of methane and carbon dioxide. It can be refined into gas that meets the standards of bio-natural gas through purification processes such as desulfurization, decarbonation, and dehydration. Biogas purification generally has the following methods: absorption method, pressure swing adsorption method, low temperature condensation method and membrane separation method. Water washing belongs to the category of absorption method. Compared with other methods mentioned above, absorption method has simple process, low equipment cost and high treatment efficiency Strengths, so it is valued by the industry. [0003] The technical information about biogas impurity removal and purification equipment can be ...
