Anaerobic reactor of horizontal flow fixed bed

Abstract

The invention relates to an anaerobic reactor of a horizontal flow fixed bed, which is characterized by comprising a shell with a top cover, wherein the lower part of one end of the shell is provided with a feed port, and the upper part of the other end is provided with a discharge port; the top of the shell is provided with a gas collection pipe; the bottom of the shell is provided with a plurality of slag discharge ports; the discharge port and the slag discharge ports are respectively provided with a filter screen; the inside of the shell is alternately provided with a plurality of diversion baffles and separation baffles in the water flow direction; and a membrane fixing carrier component is arranged between every two separation baffles on the side close to the feed port. Microbes with high density are stably fixed on the carrier, thereby preventing the microbes from being lost with water flows, and ensuring the stable and high gas production efficiency of the reactor. The invention has the characteristics of heat resistance, acid resistance, alkali resistance, favorable formability and the like, and be widely used for producing marsh gas by carrying out anaerobic fermentation on various livestock / fowl culture wastes, organic waste water in processing industry, and urban / rural domestic sewage.

Description

technical field [0001] The invention relates to an anaerobic reactor, in particular to a horizontal flow fixed-bed anaerobic reactor used in biogas engineering. Background technique [0002] The most basic requirements of the anaerobic reactor for biogas production are 1. To ensure a relatively high concentration of microorganisms in the reactor; 2. To prolong the contact opportunity and time between the reaction raw material (sewage) and microorganisms as much as possible; 3. To ensure a certain reaction temperature . In order to meet these requirements, various types of reactors have appeared so far, such as upflow sludge bed anaerobic reactors, internal circulation anaerobic reactors, fully mixed anaerobic reactors, and baffle anaerobic reactors. device and so on. But no matter which kind of reactor, all there is following problem: 1, in the reactor, keep a large amount of sludge as the means of guaranteeing microbial quantity, its problem is that the space of reactor w...

Problems solved by technology

But no matter which kind of reactor, all there is following problem: 1, in the reactor, keep a large amount of sludge as the means of guaranteeing microbial quantity, its problem is that the space of reactor will increase, and when water flow is big, sludge is easily lost and Affect the effect, when the water flow is small, the sludge is easy to settle and affect the effect; 2. In order to maintain the sludge layer under the water layer and prolong the distance (time) of the water flow through the sludge layer, the shape of these reactors is designed to be a long tower. As a result, it is difficult or impossible to keep warm in the cold season in the north and stop producing gas
