An energy-saving biogas dehydration pretreatment equipment

Abstract

Then invention discloses energy-saving biogas dehydration pretreatment equipment. The equipment comprises a gas storage tank, wherein the upper side of the gas storage tank is fixedly connected with a upright column, the upper end of the upright column is fixedly connected with a driving box, the inside of the driving box is provided with a driving cavity, the inside of the driving cavity is provided with sliding cavities, and the insides of the sliding cavities are connected with an exchange assembly in a sliding manner. According to the equipment, an action of replacing a reagent in traditional chemistry is replaced by a rotation exchange structure, working procedures are reduced, and a condensation manner is adopted to avoid the problem of producing by-products under chemical treatment. At the same time, a valve structure that resists slipping is used to automatically open or close gas supply pipelines, safety during an equipment operation process is ensured, and occurrence of accidents is prevented. A spirally wound condensing plate structure is used to ensure that a gas can be fully contacted with a low-temperature wall body before the gas is discharged, gases in left and right exchange positions are different, and a manner of first cooling and then introducing biogas for treatment by rotation in sequence is efficient and convenient.

Description

technical field [0001] The invention relates to the technical field of energy regeneration, in particular to an energy-saving methane dehydration pretreatment equipment. Background technique [0002] In the process of anaerobic fermentation of organic matter to produce biogas, the biogas contains 5.98% water vapor by weight. When the biogas is used, the water vapor may cause dangers such as explosion, which poses a great safety hazard. Therefore, the water vapor in the biogas must be removed . In the prior art, chemical reagents are used to absorb water vapor in biogas. Although the water removal effect is good, the chemical reagents often need to be replaced, the maintenance is complicated, and the cost is high enough to save energy, resulting in low water removal efficiency and chemical reactions. When the environmental conditions change, by-products will be produced, which will pollute the environment and are not environmentally friendly. The present invention illustrat...
