Embodiment Construction

[0038] The present invention will be further described with reference to the accompanying drawings.

[0039] This embodiment discloses a horizontal plug-flow anaerobic reactor for kitchen waste materials, such as Figure 1~3 As shown, it includes a biogas tank 1, a dehydrator 2 and at least one anaerobic reaction tank; the anaerobic reaction tank includes a tank body 3, and the tank body 3 is a tank structure, and adopts carbon steel anticorrosion or steel concrete structure construction; The discharge direction is the front-to-back direction, and the tank body 3 is provided with a feed pipe 4 for passing materials into the tank body 3. The feed pipe 4 is connected with a steam pipe 13, and the steam enters the feed pipe 4 through the steam pipe 13 and is discharged. The material in the feed pipe 4 is heated, and the heated material enters the tank body 3 through the feed pipe 4; the bottom of the tank body 3 forms a slope structure 5, and the slope structure 5 is a concrete s...

Abstract

The invention discloses a horizontal plug flow anaerobic reactor for kitchen waste materials. The reactor comprises a biogas tank, a biogas booster fan, a dehydrator and at least one anaerobic reaction tank. A feed pipe is arranged on a tank body of the anaerobic reaction tank; a slope structure is formed at the bottom of the tank body, a plurality of first gas nozzles are installed on the slope structure, and are used for spraying into the tank body to achieve stirring of materials, and the materials flow to the front of the tank body along the slope structure under stirring; the biogas tankis arranged on one side of the tank body, and communicates with the inside of the tank body through a first biogas pipe; the biogas booster fan is also arranged between the tank body and the biogas tank; and the dehydrator is also arranged in the front of the tank body, and the materials enter the dehydrator to achieve solid-liquid separation by the dehydrator. The horizontal anaerobic reactor with functions of gas stirring and plug flow is innovatively developed, and can reduce the construction cost of the tank body and the whole operation cost; and meanwhile, the problem of layering of bottom accumulation materials, top scum and the like can also be effectively solved.

Description

technical field [0001] The invention relates to anaerobic treatment equipment for domestic garbage, more specifically, it relates to a horizontal plug-flow anaerobic reactor and a treatment method for kitchen waste materials. Background technique [0002] Kitchen (kitchen waste) waste is rich in a large amount of organic matter, water, and inorganic matter mixed with plastic, porcelain, and soil. Among the drained and sorted materials, the organic matter is easy to digest and has a high biogas production rate. Therefore, dry anaerobic fermentation of kitchen (kitchen waste) waste has become an important technical direction for the disposal of such materials. [0003] The Chinese patent with the authorized notification number CN104263642B discloses an integrated treatment device and treatment method for kitchen waste and fecal waste water, which includes: a mixing box, a two-phase anaerobic processor, an effluent settling tank and a boiler, and the mixing box is equipped wit...
