Description

An anaerobic engineering mixing reactor for kitchen waste, feces and sludge

technical field

The utility model belongs to the field of solid waste treatment, in particular to an anaerobic engineering mixing reactor for kitchen waste, feces and sludge.

Background technique

Food waste, feces, and sludge are the main solid wastes that currently plague the comprehensive management of the environment. At present, domestically operated anaerobic fermentation reactors can only treat the above-mentioned types of solid waste separately, and cannot realize the mixed reaction fermentation of food waste, feces, and sludge, which seriously affects the treatment efficiency and increases processing costs.

Contents of the invention

The utility model provides an anaerobic engineering mixing reactor for kitchen garbage, feces and sludge, which can realize the mixed reaction and fermentation of three substances including kitchen garbage, feces and sludge, and can collect and timely discharge scum and scum Oil for subsequent secondary digestion or other uses of the remainder of the tank.

The technical scheme that the utility model adopts is:

The upper part of the outer wall of the reactor tank is provided with four circular pipes from top to bottom, which are respectively connected to the sludge inlet, the feces inlet, the supernatant outlet, and the food waste inlet; the two sets of stirring devices are suspended and fixed On the top of the reactor tank; the top of the reactor tank is provided with a biogas outlet to connect with the biogas collection device, the bottom is provided with an inspection port, and a circle of scum and oil slick collection tank is set above the annular pipe, and the scum and oil slick outlet It communicates with the scum and floating oil collection tank; several heating devices are evenly distributed in the reactor tank.

A cleaning device is arranged inside the reactor tank.

The stirring device is a vertical screw blade agitator, and the screw ribbons and paddles are alternately distributed.

The beneficial effects of the utility model are:

(1) Realized the mixed reaction fermentation of food waste, feces and sludge;

(2) The double-vertical screw blade agitator can realize the mixing of substances with different viscosities, and can destroy the structure of large flocculent and agglomerate substances to achieve uniform mixing;

(3) The oil scum collection and removal system can realize the separation of oil, liquid and slag, which is convenient for the subsequent treatment of the remaining residue.

Detailed ways

The utility model provides an anaerobic engineering mixing reactor for kitchen waste, feces and sludge, which will be further described below in conjunction with the accompanying drawings and specific implementation methods.

Structure of the present utility model as shown in Figure 1. The upper part of the outer wall of the cylindrical reactor tank 11 is provided with four annular pipes from top to bottom, which are respectively connected to the sludge feed port 1, the feces feed port 2, the supernatant liquid outlet 6, and the kitchen waste feed port 3. connection; two sets of stirring devices 10 are suspended and fixed on the top of the reactor tank 11; the top of the reactor tank 11 is provided with a biogas outlet 9 to connect with the biogas collection device, the bottom is provided with an inspection port 5, and a circle of floating The scum and oil slick collection tank 8, the scum and slick oil outlet 7 communicate with the scum and slick oil collection tank 8; several heating devices 4 are evenly distributed in the reactor tank 11. A cleaning device 12 is arranged inside the reactor tank body 11 .

The stirring device 10 is a vertical propeller blade stirrer, the structure of which is shown in FIG. 2 . One end of the transmission shaft 102 is connected with the transmission device 101 , and staggered ribbons 104 and paddles 105 are installed on the transmission shaft 102 .

When in use, sludge, feces, and kitchen waste enter the reactor evenly through their respective circular pipes, and are implanted with anaerobic bacteria. The stirring device is turned on to destroy the large mass of substances and achieve uniform mixing of the three substances. At the same time, the heating device maintains the temperature in the tank at about 40°C to facilitate the growth and reproduction of anaerobic bacteria. After the reaction is complete, the upper and lower layers of the reactor are distinct, from top to bottom are scum and slick oil, supernatant and residual residue. The biogas generated during anaerobic fermentation enters the gas storage tank through the biogas outlet on the top of the tank; the scum and oil slick produced by the reaction are collected through the scum and oil slick collection tank and discharged through the scum and oil slick outlet for subsequent treatment ; The supernatant produced after the reaction is discharged through the supernatant outlet; finally, the residue in the tank is discharged through the slag discharge port at the bottom of the tank. During the reaction process, the growth environment of anaerobic bacteria in the tank is maintained by a heating device. The cleaning device extends into the tank from the top for cleaning inside the tank.
