Problems solved by technology

The corn cob charcoal rods produced at such a high temperature have high hardness and strength, and less porosity. They can be used as charcoal for industrial and residential purposes, but they are not suitable for slow-release fertilizer substrates.
Moreover, the carbonization furnace and production process are complicated, and the production cost is relatively high

Embodiment 1

[0037] Example 1 Carbonization furnace

[0038] The carbonization furnace consists of a furnace body 1, a burner 4, an exhaust port 5, and a discharge port 2, as shown in Figure 1. In order to reclaim the wood vinegar discharged in the exhaust port 5, the exhaust port is connected with the water circulation gas condensation system to reclaim the wood vinegar. The body of the carbonization furnace is made of 8mm thick double-layer steel plate, and asbestos silk is used as the middle insulation interlayer. The furnace body is in the shape of a cuboid. The furnace body is semi-closed, with no cover on the top. The specific parameters of the special carbonization furnace for corncob granular carbon are shown in the table below. At the bottom of the narrower side of the furnace body 1, there is a discharge opening 2 for discharging and igniting the burner from the discharge opening. The outlet is square or semicircular. The size of the discharge port can be designed according ...

Embodiment 2

[0040] Example 2 Carbonization furnace

[0041] This embodiment is substantially the same as Embodiment 1, except that the furnace body is made of 6mm steel plate. The furnace body is cylindrical, and an exhaust port is provided on the opposite side of the discharge port. There is a mesh sliding door outside the discharge port. The burner is made of 3mm steel plate and is semi-cylindrical. The temperature controller is planted in the material in the furnace body. The outer dimension of the furnace body is reduced by one time according to the ratio of embodiment 1.

Embodiment 3

[0042] Example 3 Carbonization Furnace

[0043] This embodiment is substantially the same as Embodiment 1, except that the furnace body is made of 10mm steel plate. The furnace body is in the shape of a cube. The discharge port is triangular, and there is a plate type side sliding door outside the discharge port. An exhaust port is arranged on the side of the discharge port, and the exhaust pipe is in the shape of a triangular column. The burner is made of 7mm steel plate and is semi-cylindrical. The outer dimensions of the furnace body are doubled according to the ratio of embodiment 1.

Abstract

A simple charring furnace for corn cob particles and its charring process are disclosed. Said charring process features that the corn cob particles are dry-distilled and decomposed at 260-450 deg.C in anoxic condition and the quantity of supplied O2 is controlled by the thickness of raw material. The charred particles can be used as the matrix of slow-release compound fertilizer.

Description

technical field [0001] The invention relates to a special carbonization furnace for producing a carbon-based slow-release fertilizer matrix by using corncob particles and a granular carbon production method. Background technique [0002] At present, the production of carbon from corncobs at home and abroad mainly adopts the process of crushing and extruding to make rods, and the process of dry distillation in a fully enclosed high-temperature carbonization furnace. In the process of extruding rods, the microporosity of the raw material itself is substantially damaged. The charcoal rods produced by this process are used as slow-release compound fertilizer substrates, which need to be crushed again. After crushing and extruding to make rods, high-temperature carbonization, and crushing, the corn cob carbon not only changes its structure and weakens its adsorption capacity, but also has complicated processes and increased production costs. It is produced by directly heating h...
