Fast and environment-friendly straw treating method and device

Abstract

The invention discloses a fast and environment-friendly straw treating method. The method comprises the steps that crushed straw is incinerated in a sealed container, and plant ash generated after incineration is returned to the field; generated smoke sprayed water mist is dedusted, harmful substances in the smoke sprayed water mist are adsorbed by adsorbing substances, and then the smoke sprayed water mist is exhausted into the atmosphere; and after treatment is completed, a device is moved to a next straw pile. The invention discloses the treating device which comprises a transporter, and an incinerator, a steam boiler, a purification can and a pulverizer which are mounted on the transporter. The pulverizer is connected with a feed inlet of the incinerator through a conveyer; the steam boiler is arranged on the incinerator; the purification can is partitioned into a dedusting cavity and a smoke removing cavity; the dedusting cavity communicates with the smoke removing cavity through a connecting pipeline; the dedusting cavity is provided with spray pipes connected with a steam port of the steam boiler through a steam pipe; the dedusting cavity is connected with an air outlet of the incinerator through a smoke exhaust pipe; and the smoke removing cavity is filled with adsorbing substances, and an air exhaust pipe is arranged at the top end of the smoke removing cavity. According to the fast and environment-friendly straw treating method and device, operation is convenient, the cost is low, the straw treating efficiency is high, the straw treating time is short, and the smoke purification effect is good.

Description

technical field [0001] The invention relates to the technical field of straw treatment, in particular to a rapid and environment-friendly treatment method and device for straw. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium and organic matter. It is a multi-purpose renewable biological resource. The calorific value of every two tons of straw is equivalent to one The energy produced by tons of standard coal, and the average sulfur content is only 3.8‰, that is, the sulfur content in standard coal is 26 times that of straw. During the recycling of biomass, the emitted CO 2 CO absorbed by biomass 2 Achieving carbon balance and realizing zero emissions...

Problems solved by technology

[0003] Every spring and autumn in our country is the harvest season of wheat and rice, and a large amount of crop stalks will be burned on the spot on the field, which not only causes serious air pollution, but also makes it difficult to control the burning and ignition, and burns other crops and forests. cause a fire

If the crop straw scattered on the field is transported to the designated recycling point or treatment site, not only will it require enough labor, but it will also incur a large transportation cost. Farmers are often unwilling to invest too much labor and financial resources for this.
