Novel marsh gas pretreatment device

Abstract

The invention discloses a novel marsh gas pretreatment device which comprises a filter tank. The filter tank is connected with a marsh gas collection tank. Marsh gas is collected from the marsh gas collection tank, and marsh gas in the marsh gas collection tank is usually extracted through a fan and infiltrated to the filter tank. The filter tank comprises a tank body. A partition plate for dividing the tank body into an upper part and a lower part is arranged in the tank body. An opening is reserved in the middle of the partition plate. An air inlet cavity is arranged at the bottom of the tank body. A primary filter chamber is arranged on the upper side of the air inlet cavity. A secondary filter chamber is arranged above the partition plate. A condensation drying chamber is arranged above the secondary filter chamber. A vibration frame is further arranged in the air inlet cavity. The novel marsh gas pretreatment device has the advantages that design is reasonable, the structure is simple, gas entering the device is divided into two flows due to the fact that the independent air inlet cavity is arranged, one flow of gas is exhausted and changed to be in irregular flow direction through an air exhaust hole formed in a spiral air inlet pipe and then collides and interferes with the other flow of gas to achieve the speed reduction effect, natural clinoptilolite is arranged in a baffle to be used as an adsorbing agent, and the effect of primary purification and filtration on 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 novel biogas pretreatment 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 plant establ...
