Sludge fermentation device with deodorization function

Abstract

The invention discloses a sludge fermentation device with a deodorization function. The sludge fermentation device comprises a fermentation tank and a spray component, wherein a feed pipe and an air outlet pipe are arranged on the upper part of the fermentation tank; the air outlet pipe is connected with the spray component; a discharging hole is formed in the bottom of the fermentation tank; a bracket is arranged at the upper end of the fermentation tank; a cylinder is arranged on the bracket; the rod end of the cylinder is connected with a lifting table; an inner gear ring is arranged on thelifting table; a first motor is fixedly arranged on the lifting table; the shaft end of the first motor is connected with a gear; the gear is meshed with the inner gear ring; the inner gear ring is fixedly connected with a mounting plate; a rotating shaft is fixedly arranged on the mounting plate; and stirring paddles are arranged on one section, which is positioned in the fermentation tank, of the rotating shaft. According to the sludge fermentation device disclosed by the invention, odor in the fermentation process can be collected to the spray component by the air outlet pipe and then purified so as to discharge. Since the stirring paddles in the fermentation tank can rotate and can also move up and down, the stirring paddles can move up and down to another position II to stir after stirring at a position I, so that the sludge is uniform to stir.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge fermentation device with a deodorizing function. Background technique [0002] With the development of cities, a large amount of water resources are consumed and polluted. Now, China has built a large number of urban sewage treatment plants to treat the polluted water resources. However, a large amount of sludge produced by sewage treatment plants is extremely difficult to treat due to the large amount of pollutants and heavy metals contained in the sludge. With the current treatment technology, not only the treatment cost is extremely high, but also it is easy to cause secondary pollution to the environment and affect people's health. [0003] At present, there are many sludge treatment methods, and the commonly used treatment methods include sanitary landfill, drying, sludge incineration, etc., and the comprehensive utilization treatment technolog...

AI Technical Summary

Problems solved by technology

[0005] 1. The sludge needs to be stirred during the composting process, but the composted sludge is hydrophilic and is easy to stick to the stirring paddle, resulting in difficulty in stirring and uneven stirring

[0006] 2. During the conversion process, a large amount of odor will be generated, which will have a great impact on the surrounding environment, and the processing capacity will be small, resulting in secondary pollution
