Country human and animal excrement smoldering treatment device and method

Abstract

The invention discloses a country human and animal excrement smoldering treatment device and method. The device comprises an excrement storage box, a sand and excrement stirring box, a sand storage box, a stirrer, a smoldering reaction container, an air compressor, an electric heater, temperature difference power generating sheets and a smoke purifier. The excrement storage box is connected with the sand and excrement stirring box. The sand storage box is connected with the sand and excrement stirring box through a first spiral conveyor. The sand and excrement stirring box is connected with the smoldering reaction container through a second spiral conveyor. The upper portion of the smoldering reaction container is connected with the smoke purifier through a smoke pipeline. The temperaturedifference power generating sheets are evenly arranged on the middle layer of the smoldering reaction container. The tops of the temperature difference power generating sheets are connected with a lighting lamp. The electric heater is arranged at the lower portion of the smoldering reaction container, and the air compressor, a pressing type flow controller and the bottom of the smoldering reactioncontainer are connected through an air pipeline. According to the country human and animal excrement smoldering treatment device and method, heat generated through smoldering is converted into electric energy, and inorganic matters obtained after excrement combustion are subjected to harmless treatment; and meanwhile the heat energy generated by smoldering is converted into electric energy for family lighting.

Description

technical field

[0001] The invention relates to a device and method for smoldering treatment of human and livestock feces in rural areas, in particular to a treatment method for feces which is beneficial for converting the generated heat energy into electric energy after mixed smoldering of sand and manure. Background technique

[0002] The treatment of human and livestock manure in rural areas is relatively backward. Most of the manure is not treated and is used to irrigate farmland directly after a long period of natural fermentation. Cause germ leakage and serious pollution of groundwater. In order to solve the above problems, scholars have also proposed many methods, among which smoldering after mixing sand and manure is a relatively common one. However, after using this method, the heat generated therein has not been utilized reasonably, resulting in the loss of heat source. Therefore, it is necessary to develop a fast, economical, safe and energy efficient method. ...
