Deodorization, oxygen supply, heat collection and thermal insulation system for totally-enclosed sludge roller fertilizer making equipment

Abstract

The invention discloses a deodorization, oxygen supply, heat collection and thermal insulation system for totally-enclosed sludge roller fertilizer making equipment. The deodorization, oxygen supply, heat collection and thermal insulation system is characterized by comprising an air inlet electric valve, an oxygen supply fan, a central controller, a cyclone deduster, a biological deodorizer, a temperature sensing probe, an oxygen concentration sensing probe, a sludge fermentation roller variable-frequency transmission motor, and a solar fermentation shed, wherein a signal receiving end of the central controller wireless receives monitoring data of the temperature sensing probe and the oxygen concentration sensing probe; and a control signal output end of the central controller is connected with the air inlet electric valve, a discharge electric valve, the oxygen supply fan and the variable-frequency transmission motor of a sludge roller fermentation device. The environment-friendly control of the sludge roller fermentation device is organically combined with process factors such as temperature control, oxygen supply, drying, heat absorption, thermal insulation and the like, odor and dust pollution generated in the sludge composting fermentation process are obviously reduced, work efficiency is improved and the system has high practicability and great marketing value.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly solid waste harmless treatment and resource utilization, more specifically, it relates to an automatic deodorization device used in a fully enclosed sludge drum fertilizer plant to prevent environmental pollution Oxygen supply and thermal insulation system. Background technique [0002] As of the end of October 2009, the number of sewage treatment plants in my country has reached 1817, with a total treatment capacity of 99.58 million cubic meters per day. According to estimates, in 2008 my country's annual output of dry sludge reached 5.32 million tons. The environmental problems caused by a large amount of sludge are becoming more and more serious. On the one hand, sludge landfills cause a lot of waste of land resources, and on the other hand, harmful microorganisms and organic pollutants in sludge cause secondary pollution to the environment. Therefore, finding a sludge dispos...

AI Technical Summary

Problems solved by technology

The disadvantage is that a large amount of malodorous gas will be produced during the sludge fermentation process. If it is not effectively controlled and treated, it will inevitably cause serious pollution to the surrounding atmospheric environment, and the second is that it occupies a large area; therefore, the project's site selection is extremely difficult
