Embodiment Construction

[0022] Examples see figure 1 As shown, the tower body 1 is a cylindrical body with an inverted conical bottom, and the bottom of the inverted tapered cylindrical cylinder is fixed on the support 19. The diameter of the tower body is 4 to 8 meters, and the height is 10 to 18 meters. There is a closed top cover 15 on the top of the tower body 1, and the outside is treated with overall heat preservation. The center of the tower body 1 has a vertically placed hollow guide tube 2 equipped with a sealing cover 16, with a diameter of 600-1200 mm. The upper end of the guide tube 2 is higher than the top cover 15, and the lower end is connected to the inverted conical bottom of the tower body 1; a submersible motor 3 is fixed on the inner wall of the middle part of the guide tube, and the power is 2.2 to 11 kilowatts. The submersible motor 3 Connected with the lifting impeller 4, the side wall of the guide tube 2 communicates with the upper and lower layers of radially distributed guid...

Abstract

The invention discloses a hydraulic cyclone anaerobic digestion tower and a using method thereof. A flow guiding cylinder is arranged in the center of a tower body, a submersible motor is arranged at the middle part in the flow guiding cylinder, the lower part of the submersible motor is connected with a lifting impeller, the flow guiding cylinder is connected with two flow guiding tubes, a circle of annular flow stabilizing plates are arranged between the upper layer flow guiding tube and the tower body, a feeding tube which is used for communicating the external and the flow guiding cylinder is arranged at the bottom on the side wall of the tower body, a slag collection bucket is connected with the bottom of the tower body, the side surface of the slag collection bucket is connected with a slag discharge tube, and a biogas tube is arranged on a top cover of the tower body and is in signal connection with a pressure transmitter and an electric control box. According to the hydraulic cyclone anaerobic digestion tower disclosed by the invention, by utilizing a mode of a hydraulic cyclone, material stirring, scum crushing as well as raw and cooked material separation are realized, the anaerobic digestion treatment efficiency is improved, the biogas yield is increased, and the energy consumption of anaerobic digestion treatment is saved; and in addition, a changed intensity anaerobic digestion process is adopted according to the pressure of biogas, so that automatic running and regulation of a biogas production and utilization system can be realized. The hydraulic cyclone anaerobic digestion tower can be widely applied to anaerobic digestion treatment of high concentration organic wastes such as waste water, waste liquor, wastes, excrement, sludge and the like.

Description

technical field [0001] The invention relates to an organic waste treatment device. Background technique [0002] At present, in the process of harmless and resourceful treatment of high-concentration organic waste such as waste water, waste liquid, garbage, feces, and sludge, anaerobic digestion process equipment is often needed. Existing various types of anaerobic digestion equipment mostly use mechanical agitation or biogas mixing, but this kind of equipment is easy to form a surface scum layer when it is working, and it is impossible to distinguish between raw meal and clinker, resulting in a large proportion of raw meal in the discharged biogas residue. In addition, traditional equipment has low working efficiency and high energy consumption. Moreover, it is impossible to adjust the biogas production in real time according to the biogas utilization, resulting in waste. Contents of the invention [0003] The purpose of the present invention is to provide a hydrocyclone...
