Abstract
The utility model relates to a carbonization furnace, which comprises a furnace body and a combustion chamber. Heat insulating material is integrally coated on the periphery of the furnace body, a feeding opening and a discharging opening are arranged on the furnace body, a waste heat recovery tube is arranged on the carbonization furnace and respectively connected with the furnace body and the carbonization furnace, and an ignition device is arranged at the outlet opening of the waste heat recovery tube. The utility model enables the flammable organic matter flue gas generated during the carbonization process to be introduced into the combustion chamber for combustion, and the tail gas of the carbonization furnace can be fully burnt, therefore, the environmental pollution is reduced, the smoke evacuation temperature is decreased, the heat erosion of high temperature gas to chimneys is reduced, the heat generated through combustion is recovered to be taken as carbonization heat sources, therefore, not only the energy is saved, but also the production cost is reduced.
Description
(1) technical field
The utility model relates to a kind of charring furnace.
(2) background technology
Charing is under anoxic and hot conditions, the raw material pyrolysis is formed the carbon structure body of many ceasmas property.Existing charring furnace generally includes body of heater, combustion chamber, and the peripheral integral coating of body of heater has the bag adiabator, and body of heater is provided with opening for feed and discharge port.During work, raw materials such as wood chip at high temperature carry out charing, produce flammable organism flue gases such as a large amount of naphthalenes, benzene, methane in the carbonization process, part enterprise directly enters atmosphere with this organism, other enters atmosphere after having part enterprise with this organic compound combustion, perhaps cause environment, perhaps caused energy dissipation.
(3) utility model content
Technical problem to be solved in the utility model is to provide a kind of charing flue gas of recycling effectively, reduces the charring furnace of environmental pollution.
Charring furnace of the present utility model comprises body of heater, combustion chamber, and the peripheral integral coating of body of heater has the bag adiabator, body of heater is provided with opening for feed and discharge port, described charring furnace is provided with the waste heat recovery pipe, and the waste heat recovery pipe connects body of heater and combustion chamber respectively, and waste heat recovery pipe exit is provided with portfire.
Further, described body of heater one side is installed rotating shaft, and rotating shaft is connected with motor drive driving motion.
Further, described waste heat recovery pipe is provided with regulated valve.Regulated valve reaches the purpose of regulating carbonization temperature by the amount that adjusting enters the flammable flue gas of combustion chamber, and unnecessary flammable flue gas can enter atmosphere again or be used for burning boiler to produce hot water, hot vapour after pipeline is introduced the elsewhere burning.
The utility model is introduced the combustion chamber with the flammable organism flue gas that produces in the carbonization process and is burnt, charring furnace tail gas was fully burnt, reduced environmental pollution, reduced funnel temperature, reduce of the thermal etching of wet body to chimney, the heat that has reclaimed the burning generation again uses to do the charing thermal source, has both saved the energy, has reduced production cost again.In addition, body of heater is the average rate rotation under motor drives, makes that raw material charing in body of heater is even, complete.
(4) description of drawings
Fig. 1 is the structural representation of the described charring furnace of embodiment.
(5) embodiment
The invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this.
With reference to Fig. 1, a kind of charring furnace, comprise body of heater 1, combustion chamber 2, body of heater 1 peripheral integral coating has bag adiabator 3, body of heater 1 is provided with opening for feed and discharge port, described charring furnace is provided with waste heat recovery pipe 4, and waste heat recovery pipe 4 connects body of heater 1 and combustion chamber 2 respectively, and waste heat recovery pipe 4 exits are provided with portfire 5.
Described body of heater one side is installed rotating shaft 6, and rotating shaft 6 is in transmission connection with electric motor 7.
Described waste heat recovery pipe 4 is provided with regulated valve 8.
In the carbonization process, produce flammable organism flue gas by the raw materials such as making wood chip of igniting earlier, flammable organism flue gas is introduced combustion chamber 2 through waste heat recovery pipe 4 and is burnt, no longer need other thermal source during charing, both save the energy, reduced production cost, reduced environmental pollution again.
Claims (3)
1. charring furnace, comprise body of heater, combustion chamber, the peripheral integral coating of body of heater has the bag adiabator, body of heater is provided with opening for feed and discharge port, it is characterized in that: described charring furnace is provided with the waste heat recovery pipe, the waste heat recovery pipe connects body of heater and combustion chamber respectively, and waste heat recovery pipe exit is provided with portfire.
