Abstract

A process of producing charcoal from branches and barks of hazelnut. It comprises, screening and cracking disposed branches, barks of hazelnut, drying the mixed material of branches and barks of hazelnut in a dehydrator, and sending it into a coal-making machine to produce carbon pencils, sending carbon pencils into a charring oven to produce charcoal, the coal content is above 85%, the calorie value is above 8500 kcal, recycling combustible gases produced in making coal to be fuel for burning ceramic products. The invention saves cost and protects resources, and prevent new environment pollution.

Description

Hazel bar, hazel skin regenerative system charcoal

Technical field

The present invention relates to a kind of machine-made charcoal that utilizes the waste production of agriculture native article, particularly relate to a kind of hazel bar, hazel skin regenerative system charcoal, belong to the technical field of waste ' s reclamation.

Background technology

Charcoal be timber or wood material through incomplete combustion or under the condition of secluding air pyrolysis residual porosu solid fuel, because of its efficiency of combustion height, no flue dust are widely used.Traditional charcoal by quality preferably timber fire and form, along with the development of society and the step of satisfying of the forest reserves reduce, the supply growing tension of charcoal, and hazel is a kind of perennial machaka, be distributed widely in the low mountains and hills mountain of domestic northeast, North China, northwest, its nut is one of famous native article, and the Development and Production of fibert has been made contribution for shaking off poverty and setting out on the road to prosperity of peasant in recent years.But the hazel bar that intermediate cutting gets off can only be made common burning material, and the hazel skin that takes off behind the son is then arbitrarily abandoned, and promptly wastes resource contaminate environment again.For replacing valuable timber resources, once there was a kind of technology of utilizing the alditol slag to replace the charcoal processing of timber making machine in market, but because of its alditol slag that squeezes out rod intensity little, the percentage of damage height, low former of yield rate thereby can't promote the use of, also there is at present people's research and utilization shell the like waste to produce the technology of charcoal, a kind of " processing method of production mechanism charcoal and the machine-made carbon shaper " that for example provides for Chinese invention patent ZL98112685.5 number, promptly with shell, wood chip and plant stem are with raw material, through pulverizing, be pressed into bar-shaped in the machine-made carbon shaper of packing into special after the drying, moulding stick packed into take off the cigarette charing in the stove, cooling again; The material of pulverizing is 40～60 orders, and the water content of dry back material is lower than 10～15%, and the pressure of compression moulding is 15～25 MPas, temperature is 150～200 ℃, and carbonization temperature is 250～400 ℃, and carbonization time is 8～12 hours, be incubated 2～6 hours, cooling temperature is lower than 50～60 ℃.Above-mentioned processing requirement can't realize hazel bar, hazel skin are made machine-made carbon as raw material, and this technology does not reclaim the available gas that produces in the charcoal processing process, let alone utilize and reclaim the available gas that produces in the charcoal processing process, the production other products acts as a fuel.

Summary of the invention

The objective of the invention is to overcome the above-mentioned deficiency of prior art, by to existing improvement of firing machine-made carbon, a kind of brand-new hazel bar, hazel skin regenerative system charcoal have been provided, the characteristics of this kind machine-made charcoal are that quality is hard, carbon content is more than 85%, calorific value is more than 8500 kilocalories, combustion time, length was more than three times of other charcoal, and smokeless, tasteless, nontoxic, was more purified fuel.Every cubic metre fibert bar, fibert skin can produce 9.7 cubic metres of inflammable gass again in firing the process of charcoal, and be recyclable as the fuel of producing other products.

The technical solution that the present invention provides is: this hazel bar, hazel skin regenerative system charcoal are to be made by following steps:

1. raw material is prepared

With depleted hazel bar, hazel skin is raw material, and puts screening in order and be ground into particulate state after choosing foreign material in the particle pulverizer, and granularity is 2～3mm, the moisture content of hazel bar, hazel skin compound by its freshness generally 10～30%;

2. oven dry system rod

After hazel bar, hazel skin compound dried in dryer, (its moisture being controlled at below 5%) sent into the charcoal processing machine, 200 tons of its operating pressure, 500～1000 ℃ of working temperatures, made that 600mm is long, diameter is the carbon rod of 5cm;

3. sintering charcoal processing

The carbon rod that makes is sent into charring furnace, 400～450 ℃ of sintering temperatures, 10～14 hours time, under sealed state, carry out nature and become charcoal, being cooled to 30～40 ℃ comes out of the stove, its carbon content is more than 85%, and calorific value is more than 8500 kilocalories, and the inflammable gas that will produce in charcoal processing process recovery causes the high-pressure gas tank stores.

Compared with prior art, the beneficial effect of this hazel bar that the present invention provides, hazel skin regenerative system charcoal is: major equipments such as particle pulverizer used in the present invention, charcoal processing machine, charring furnace, and all can purchase from the market, and need not particular design; When getting charcoal, also reclaim the inflammable gas that produces in the charcoal processing process with hazel bar, hazel leather; Both reduced production cost, and protected valuable forest resources again, and promptly accomplished comprehensive utilization, fork prevents to produce new environmental pollution.Obtained product charcoal and inflammable gas all have selling market preferably.

Embodiment

Below in conjunction with the embodiment that provides concrete technical scheme of the present invention is described further:

This hazel bar that the present invention provides, hazel skin regenerative system charcoal, be with depleted hazel bar, the hazel skin is a raw material, and put screening in order and in the particle pulverizer, be ground into particulate state after choosing foreign material, granularity is 2～3mm, the hazel bar, the moisture content of hazel skin compound is pressed its freshness generally 10～30%, again with the hazel bar, after hazel skin compound is dried in dryer, (its moisture being controlled at below 5%) sends into the charcoal processing machine, 200 tons of its operating pressure, 500～1000 ℃ of working temperatures, it is long that per minute makes 600mm, diameter is one of the carbon rod of 5cm, then the carbon rod that makes is sent into charring furnace, 400～450 ℃ of sintering temperatures, 10～14 hours time, carry out nature and become charcoal under sealed state, be cooled to 30～40 ℃ and come out of the stove, every stove can produce 20 tons in charcoal, its carbon content is more than 85%, calorific value more than 8500 kilocalories, every cubic metre hazel bar in the charcoal processing process, the inflammable gas that the hazel micromicro produces is 9.7 cubic metres, and the inflammable gas recovery that produces is caused the high-pressure gas tank stores.

The inflammable gas quality that hazel bar, hazel skin produce in the charcoal processing process is better, is fit to the high-temperature firing product, and firing temperature can reach 1300～1400 ℃ or higher, the consisting of of its gas (volume %): hydrogen 55～60, methane 23～27, carbon monoxide 5～8, C ₂Above unsaturated hydrocarbons 2～4, carbonic acid gas 1.5～3, nitrogen 3～7, hydrogen 0.3～0.8.
