Livestock and poultry waste harmless sterilization waste heat recovery device

Abstract

The invention discloses a livestock and poultry waste harmless sterilization waste heat recovery device. The waste heat recovery body is provided with an air inlet, a first air outlet, an atmosphere inlet and a second air outlet. Two ends of an air outlet pipeline are respectively communicated with a fermentation tank and the air inlet; an ozone generator is arranged in the waste heat recovery main body; one end of an induced draft fan is communicated with the first air outlet, and the other end of the induced draft fan is communicated with a chimney pipeline; a finned tube is arranged in thewaste heat recovery main body; the finned tube is communicated with the atmosphere inlet; and the second air outlet is communicated with the fermentation tank. Through the arrangement of the structure, heat energy generated by fermentation of the livestock and poultry waste harmless treatment equipment can be recycled, secondary pollution of the air is avoided through ozone deodorization treatment, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry waste treatment, in particular to a waste heat recovery device for harmless sterilization of livestock and poultry waste. Background technique [0002] In recent years, my country has emphasized environmental protection in the livestock and poultry breeding industry, and the emergence of livestock and poultry waste treatment equipment can effectively solve the pollution problem in the breeding industry. At present, the harmless treatment equipment for livestock and poultry waste has become a new type of high-efficiency treatment equipment for livestock and poultry and domestic waste treatment in farms. [0003] Livestock and poultry waste harmless treatment equipment ferments livestock and poultry waste, livestock and poultry organic waste, and domestic organic waste, and uses a combination of high-pressure fans and electric heating to supply air to the tank for heating. The heat gen...

AI Technical Summary

Problems solved by technology

[0003] Livestock and poultry waste harmless treatment equipment ferments livestock and poultry waste, livestock and poultry organic waste, and domestic organic waste, and uses a combination of high-pressure fans and electric heating to supply air to the tank for heating. The heat generated by fermentation in the tank is discharged through direct air or directly Washing and spraying directly waste heat energy, and the fermentation in the tank must be continuously heated by a hot air blower, which will inevitably cause energy loss

The harmless treatment equipment for livestock and poultry waste needs to maintain electric heating continuously, so that the power used in the fermentation process of the equipment will increase, and at the same time, it will increase the cost of waste treatment for farmers

At the same time, direct discharge causes secondary air pollution

[0004] The currently widely used harmless treatment equipment for livestock and poultry waste uses relatively high-power motors and fans, as well as high-power electric heating rods, which increases the cost of fermentation and fails to achieve the effect of energy saving and environmental protection
