A rapid fuelization device for domestic waste

Abstract

The invention discloses a fast fuel conversion device for household waste. The fast fuel conversion device comprises a stirring shaft, a two-way discharge device, a heat exchange plate and a waste liquid separator, one end of the stirring shaft is connected with a transmission mechanism for transmission, the other end of the stirring shaft penetrates through a tank, and stirring blades are fixed to the stirring shaft at equal distances through bolts, each stirring blade comprises a front side and a reverse side, flow guiding grooves are distributed on the front sides and the reverse sides in astaggered mode, the shape of the flow guiding grooves in the front sides is trapezoidal, the shape of the flow guiding grooves in the reverse sides is inverted trapezoidal, the two-way discharge device extends into and is fixed to the upper part of the tank, and the two-way discharge device comprises a straight stroke electric actuator, an exhaust regulating spring, an air inlet regulating springand a valve element. (1), in the early stage of pressurization, the double-sided flow guiding grooves of the stirring blades are used for assisting dehydration under the pressurizing action of the stirring blades, the better dehydration effect is achieved; and (2), through the two-way discharge device, a pressure regulating unit for feeding and discharge regulation of the pressure in the tank ofthe fast fuel conversion device for the household waste is achieved.

Description

technical field [0001] The invention relates to a domestic waste fuelization device, in particular to a domestic waste rapid fuelization device. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage generated in the process of urban production and life has also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people. Health effects are also becoming more apparent. The massive increase of municipal solid waste has made it more and more difficult to dispose of waste, and the resulting environmental pollution and other issues have gradually aroused widespread concern from all walks of life. The country attaches great importance to environmental protection issues, and has made great progress in the prevention and control of domestic waste and sewage. However, while the output of urban waste in my country c...

Problems solved by technology

[0003] The existing devices for domestic waste treatment include double-layer reactors and single-layer reactors. Due to the limitation of the manufacturing process of the double-shell structure, the optimal pressure range for the applicable operation is below 3.0MPa and below 250°C. Temperature, has the disadvantages of slow temperature rise and pressure rise, and incomplete degradation of refractory organic substances such as plastics. The single-layer reactor is a single-layer shell that is in direct contact with steam, and the pressure and temperature rise are fast, but the amount of steam used is large, and the steam condenses It is difficult to recycle the liquid directly into the product, which eventually leads to a high moisture content of the product. The product needs to be dehydrated and dried until the moisture content is lower than 30% to meet the requirements. The overall process energy consumption is too high, the operating cost is too high, there is no good process control, relatively The system will not be able to be put into practical use due to the perfect sorting and treatment of regional garbage of a specific nature. At the same time, there is no single-layer reactor steam rapid heat exchange and condensation hydrophobic recovery device on the market, and there is no waste in the reactor and waste liquid in the reaction process. separation device
