Problems solved by technology

Use it directly as fuel, the calorific value is low, it is not suitable for fire, and the smoke is too large to be directly used as fuel
Therefore, most of them are discarded in the field ditch and left to rot, or burned in the open air, which pollutes the air and the environment, wastes resources, and is easy to cause fires. Therefore, it is very necessary to use straw to make charcoal as fuel.

Embodiment Construction

[0020] 1. First press figure 1 The way to build carbonization kiln. Such as figure 1 As shown, dig a rectangular kiln pool 2 of length * width * height=4 * 3.5 * 1 meter below the ground, and use brick walls on all sides; A chimney 1 with a height of 5 meters and an inner diameter of 0.5 meters is built next to the kiln pool 2. Process fire grate 3 with steel plate, and its shape is that iron plate is folded into continuous concave-convex groove. Drill air holes 4 on the facade of the fire grate 3, the row spacing of the air holes 4 is 3 × 2 cm, and the diameter is 1 cm. A pad 6 is arranged at the bottom of the rectangular kiln pool 2, and the fire grate 3 is placed on the pad 6 . A flue 5 is formed below the fire grate 3, and the flue 5 communicates with the chimney 1.

[0021] 2. Use a grinder to crush the collected straw into 1.5 cm long pieces, dry it naturally, and test that the moisture content is not more than 20%;

[0022] 3. Spread dry firewood in the kiln and ig...

Abstract

The invention discloses a straw carbon, which comprises the following steps: building charring kiln; grinding the straw into 1.5 cm length material with less than 20 percent water content; paving dried bavin in the kiln to ignite; controlling the kiln temperature at 300-600 deg.c for 8-16 h in the oxygen separation and limit condition; making all filler char completely; injecting water in the kiln after the filler becomes black; cooling and extincting instantaneously to produce charring material; remaining residual flame if producing next kiln; continuing to fill material to circulate those steps.

Description

technical field [0001] The invention belongs to the treatment and utilization of straw wastes, in particular to making charcoal with straws. Background technique [0002] After the crops are harvested, a large amount of stalks will be discarded, such as some soft stalks such as corn stalks, sorghum stalks, and wheat stalks. Using it directly as fuel has a low calorific value and is not suitable for fire, and the smoke is too large to be directly used as fuel. Therefore, most of them are discarded in the field ditch and left to rot, or burned in the open air, which pollutes the air and the environment, wastes resources, and is easy to cause fires. Therefore, it is very necessary to use straw to make charcoal as fuel. Contents of the invention [0003] The purpose of this application is to invent a straw-type charcoal to solve the problem of smokeless combustion of straw. [0004] The method of the present invention is; [0005] 1. Build a carbonization kiln [0006] The...
