Embodiment 1

[0023] see figure 1 The invention provides a biogas purification absorption filter device, which is used as a primary filter device in the biogas purification pretreatment process, including a filter tank, which is connected with a biogas collection tank, and biogas is collected from the biogas collection tank, usually with a fan Extract the biogas in the biogas collecting tank and put it into the filter tank, the filter tank includes a tank body 1, inside the tank body 1 is provided a partition 2 that separates the tank body 1 from top to bottom, and an opening 3 is left in the middle of the partition 2; The plate 2 is inclined to both sides along the opening 3, forming an inverted "V" shape. The upper surface of the partition 2 is an arc surface raised in the middle, and the two sides of the partition 2 are provided with diversion grooves. The deceleration chamber 21 is provided on the partition 2. , the deceleration chamber 21 is a chamber for biogas to pass through and ach...

Abstract

The invention discloses a marsh gas purification, absorption and filtration device. The device comprises a filtering tank, the filtering tank is connected with a marsh gas collection tank, marsh gas is collected from the marsh gas collection tank, generally, marsh gas in the marsh gas collection tank is extracted through a draught fan and introduced into a filtering tank, the filtering tank comprises a tank body, a partition plate which partitions the tank body vertically is arranged in the tank body, an opening is formed in the middle of the partition plate, and the opening is communicated with a gas channel of a speed reduction chamber above the opening; a gas inlet cavity is formed in the bottom of the tank body, a level-I filtering chamber is formed in the upper side of the gas inlet cavity, and a level-II filtering chamber is formed above the partition plate. The marsh gas purification, absorption and filtration device has the advantages of being reasonable in design and simple in structure; the independent gas inlet cavity is formed, so that gas entering the gas inlet cavity is divided into two flows, and by means of gas vents formed in a spiral air inlet pipe, a flow of gas is discharged and changed into irregular flow direction and collides with the other flow of gas, so that the speed reduction effect is achieved, natural clinoptilolite is arranged in a filter screen and serves as adsorbent, and the effect of preliminarily purifying and filtering marsh gas is achieved.

Description

technical field [0001] The invention relates to the field of development and utilization of biomass energy, in particular to a biogas purification absorption filter device. Background technique [0002] Biogas is a combustible gas with high calorific value, the main component is methane (CH 4 ) and carbon dioxide (CO 2 ) and a small amount of nitrogen (N 2 ), hydrogen (H 2 ), oxygen (O 2 ), hydrogen sulfide (H 2 S) and other gases, in which the methane content is 45% to 60%. Compared with other gases, biogas has better antiknock performance and is a good clean fuel. Traditionally, biogas is used for heating, cooking and lighting. With the continuous increase of biogas production, the medium and high-end utilization methods of biogas continue to expand. After purification and purification, biogas can be used for combined heat and power generation, incorporated into natural gas pipeline networks, vehicle fuel, chemical raw materials, and fuel cells. The Laholm biogas ...
