Crop straw carbonizing equipment

Abstract

Crop straw carbonizing equipment comprises a straw grinding machine, a feeding mechanism, a carbonizing furnace, a heating furnace, and a flue gas processing tower. The carbonizing furnace comprises an outer furnace body, a pyrolysis chamber, a carbonizing chamber, and a cooling chamber. The outer furnace body comprises a heat cavity A, a heat cavity B, and a cooling cavity. The pyrolysis chamber is arranged in the heat cavity A. The carbonizing chamber is arranged in the heat cavity B. The cooling chamber is arranged in the cooling cavity. The heat cavity A and the heat cavity B are communicated. The heat cavity B is connected to the heating furnace. The straw grinding machine is connected to the pyrolysis chamber through the feeding mechanism. The output end of the feeding mechanism is connected to the inlet end of the carbonizing chamber. The output end of the carbonizing chamber is connected to the inlet end of the cooling chamber. The output end of the cooling chamber is connected to a receiving hopper under the carbonizing furnace. The heat cavity A is communicated with the feeding mechanism through an exhaust pipe A. The carbonizing chamber is connected to a nitrogen tank through an air inlet pipe. The carbonizing chamber is connected to the flue gas processing tower through an exhaust pipe B. A spraying pipe is arranged in the cooling cavity and faces the cooling chamber. The spraying pipe is connected to a tap water main. The cooling cavity is provided with a liquid outlet. The liquid outlet is connected to the heating furnace through a liquid inlet pipe.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of agricultural waste, and relates to equipment for making charcoal from crop straws. Background technique [0002] Crop straw is an excellent biomass energy. At present, the world produces more than 2.9 billion tons of crop straw every year, and our country can produce more than 700 million tons of straw every year. Taking rice husk as an example, our country produces about 200 million tons of rice every year. It is equivalent to 40 million tons of rice husk, accounting for more than 30% of the world's total output, ranking first in the world. In the past, due to the lack of utilization of crop straws, they were usually stacked in the field and burned directly, which was not only wasteful, but also polluted the environment. [0003] Crop straw is a kind of organic matter, which is composed of combustible matter, inorganic matter and water, and mainly contains carbon, hydrogen, oxyge...
