Straw on-site carbonization machine

Abstract

The invention discloses a straw on-site carbonization machine. The straw on-site carbonization machine comprises a rack, a power transmission mechanism, a straw collecting mechanism, a straw conveying mechanism, a combustion device, a ploughing mechanism, a land covering mechanism and a tail gas treatment device; the power transmission mechanism is arranged on the rack and connected with the straw collecting mechanism and the straw conveying mechanism; the straw collecting mechanism, the straw conveying mechanism, the combustion device and the land covering mechanism are sequentially arranged on the rack from front to back, an outlet of the straw collecting mechanism is closely connected with an inlet of the straw conveying mechanism, an outlet of the straw conveying mechanism communicates with an inlet of the combustion device, and an outlet is formed in the bottom of the combustion device; the ploughing mechanism is distributed between the straw collecting mechanism and the combustion device and connected to the portion, below the straw conveying mechanism, of the rack; the land covering mechanism comprises two wing plates arranged on the two sides of the rear end of the rack in a splayed mode; and the tail gas treatment device is arranged on the rack and is connected with the combustion device.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing straw on-site carbonization machine, which belongs to the field of biomass carbonization. Background technique [0002] Straw is a resource, rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. After returning to the field, it can not only significantly increase the content of soil organic matter, but also improve the quality of organic matter, and can play an important role in agriculture and energy. It is one of the pollution-free and pollution-free renewable new energy sources in the 21st century. [0003] At present, straw is not used as fertilizer, and excess straw is the main culprit of discarded garbage, dangerous fire source and environmental pollution. There are three main methods of straw disposal. One is to directly pulverize the straw and plough the ground. This method has many disadvantages.

Problems solved by technology

[0003] At present, straw is not used as fertilizer, and the surplus of straw is still the culprit of discarded garbage, dangerous fire source, and environmental pollution.

There are three main ways to deal with straw. One is to directly crush the straw and plow the ground deeply. This method has many disadvantages. If wheat is planted after harvesting rice or corn, the straw buried deep in the ground will not rot quickly. Many wheat Seeds cannot take root and germinate because they cannot touch the soil. If they wait until they rot and plant them again, the farming time will be delayed, resulting in a large-scale reduction in crop production and farmers’ income. The straw rots very slowly when buried in the soil, and the Parasites, insect eggs, etc. will affect the root system of plants and affect the quality of the next round of crops; the straw buried in the ground protects the pests and diseases, which will aggravate the pests and diseases in the coming year, causing farmers to increase the use of pesticides and chemical fertilizers, resulting in a large Negative impacts, such as the mass death of beneficial insects and birds, heavy metal pollution in the soil, groundwater pollution, etc. The harvested food also affects human health

The second is to transport the straw away. For farmers, the cost of transporting straw is higher than the value of straw. At the same time, the transportation process also causes fuel waste and environmental pollution.

The third is to directly burn the straw (this method is the choice of most farmers), resulting in a large amount of smog pollution, but also very prone to fire, causing serious loss of life and property and environmental pollution
