Description

The present invention is a dryer, the configuration of which will be explained from the top. A rectangular box with a four-sided slant angle that can drop a kneaded product containing moisture directly from the carry-in vehicle is provided. A mesh of an appropriate size that requires strength is placed, a chimney pipe is distributed underneath it, and a plurality of small pipes through which the exhaust gas passes are installed at an interval through which the above-mentioned kneaded material passes smoothly, and further below the interval Adjustable motor with two rotating squeezing rollers mounted in parallel, opening and closing the spacing of the rotating squeezing rollers can adjust the thickness of the kneaded material passing through this roller, making a thin large mucous membrane, this same roller A large horizontal cylindrical boiler with a motorized grating mesh is wound on the bottom of the large horizontal cylindrical boiler. The mucous membrane falls, and the horizontal cylindrical boiler is adjusted by the motor so that the rotation speed of the cylinder can be adjusted according to the moisture content and dryness of the thin large mucosa falling from the heat and the upper part of the large horizontal boiler. The thin, large mucosa coming in sync with the horizontally elongated cylindrical boiler with this grating is rotated halfway, and the mucosa falls at the bottom, placed on the caterpillar for delivery, and transported out of the boiler. The inner horizontal boiler is also doubled, and the inside is a cylindrical boiler for steam generation. This steam is used for rotating the turbine of the small steam power generator, and the outside of the double cylindrical boiler keeps the high temperature of the inner steam boiler. For the purpose of heat insulation and the use of hot water in the outer cylindrical boiler. In the central inner furnace of the same double boiler, A caterpillar rotary type with a fixed base is placed, the rotation of the caterpillar is adjusted to take into account the type of combustion, and the combustion temperature in the furnace can be adjusted, making it possible to incinerate and move biomass fuel independently of any type The present invention relates to a biomass rotary dryer with a small steam generator characterized by the following.

On the earth, at present, the use of biomass energy is not used on an average of 10% of the total energy requirement, whether it is for industrial use or for daily use throughout the world.
In recent years, biofuels have been reviewed, especially due to rising oil prices, mainly in large agricultural areas in the United States, Australia and Brazil, turning food into ethanol raw materials and increasing biofuel production. The shortage is considered a problem and the price rises. Also, due to a major accident at the nuclear power plant caused by the Tohoku earthquake on March 11, 2011, it was considered difficult to install a new nuclear power generator. There is a need to develop boiler-type generators and boiler equipment that can provide hot water and steam.

Several times the amount of thermal energy that humans need for life, including non-food timber, bamboo, weeds, edible plant waste, and building waste, grow naturally. If we can develop a system that can stably use boiler hot water hot water supply and use power generation enough to build a recycling system for biomass energy that can be used in each region, Use is unnecessary, wind power and solar power generation need only be used as supplementary. Development is also urgently required to prevent global warming by establishing clean energy together with small and medium hydroelectric generators, especially for ethanol, edible plants As waste materials and squeezed wastes contain a lot of moisture, it is desired to develop a dryer exclusively for biomass that does not use fossil fuels in the dryer.

Conventionally, large-scale thermal power generators installed and operated by large power companies have been the mainstream as steam boiler generators. Recently, power generators that mainly collect garbage, dry it, pelletize it, and burn it have been developed and operated. At the same time, facilities that use boilers and hot water hot water are also being used, and demand for large dryers is increasing.

However, the above-mentioned garbage boilers, hot water hot water supply and generators are also basically required to increase power generation efficiency, and further to reduce the cost of equipment,
・ Large capital is required to increase the size of one machine.
・ Due to the increase in size, it is difficult to select the installation location.
・ There is a need to collect garbage from a wide area. Recently, the distance from the consumption area to the power plant has been seen as a problem by wide-area municipalities, and the amount of garbage brought into the power plant has been greatly reduced due to the reduction in the amount of garbage in the district. It has become less. The power generation incineration and hot water hot water supply capacity have been greatly reduced.

For this reason, it is difficult to maintain a large garbage power plant. On the other hand, instead of incinerating raw garbage in local municipalities, it is also necessary to incinerate raw garbage by converting it into fertilizer or feed. It also contributes to a reduction in the amount brought in.

Most of the conventional garbage incineration power plants are heated to high temperature and downsized power generation facilities, so this garbage is heated with high heat, dried quickly and fixed to a certain size and weight (also called RDF) ) Is converted into a biomass fuel called) and then put into incinerators for power generation and hot water hot water. Some fuels are also used with oil (heavy oil), and the overall facilities are also large and fixed. It has become.

The most recent drying equipment is the rotary type, but sugar millet, sunflower oil, rapeseed oil, mushroom fungus bed, and squeezed wastes such as corn contain 40% to 65% moisture, The mainstream is a device that puts the above-mentioned squeeze residue inside the drum, applies a flame to the outside of the drum from the bottom of the furnace, and rotates and dries the drum.

Some rotary drum dryers exclusively for biomass are manufactured, but there are few independent dryers, using commercial power purchased from many sources, powder, solid, irregular wood materials, pellets, clay It is necessary to develop a drying device that can use all of the fuels of the above, including dry matter, including the kneaded state, can continuously dry the residue, attach the necessary generators, and can be used independently regardless of the area of use. It is done.

JP 2013-245350 A JP2012-193902 JP 2001-33158 A JP2012-111913 In these patent applications, there are few compact size biomass rotating devices that can be burned and moved regardless of the type of biomass with a steam generator.

The present invention is intended to solve the problems of such conventional methods and configurations, and an object thereof is to provide a power generation combined biomass rotation apparatus that is small and inexpensive and has good combustion efficiency. Is.

The problem we are trying to solve is
(B) Is there a method for continuously drying the substance, including all the dried residue, granular and kneaded clay of the dried product?
(B) What can be done with a biomass rotary dryer that can be moved alone with a small steam generator?
