Description
Technical field
The present invention relates to produce the equipment of biomass char, particularly a kind of self-combustion biomass char production furnace that is applicable to the small-scale production biomass char.
Background technology
Biomass char (biochar) is similar to charcoal, is the solid product of biological material cracking process under high temperature (200～700 ℃), few oxygen condition, black, the light and porous of quality.It is with a long history that the kiln formula is produced charcoal, and main drawback is that length consuming time, a large amount of flue gas efflux and contaminate environment, working method are empirical strong.It is new method for producing that the equipment method is produced, and is fit to standardized production, but shortcoming is that external energy consumption is large, contaminate environment, cost are high.Therefore, Main Problems is in the present production method: 1) rely on extra power and produce hot environment, do not meet the future trend of low-carbon emission.2) a large amount of flue gases efflux, and pollutant atmosphere does not meet the actual requirement of environment protection.3) the empirical strong grasp that is difficult for of kiln formula method, equipment method energy cost is high, all should not popularize, and does not meet the megatrend of Involvement of public community low-carbon emission.
Summary of the invention
The present invention provides a kind of self-combustion biomass char production furnace for solving the problems referred to above of existing installation.
Technical scheme of the present invention is: this production stove is cylindrical, arranges and the inwall of producing the stove arranged concentric in this produces stove, and inwall is take interior part as combustion chamber; The middle part of the annular region between combustion chamber wall and production furnace outer wall arranges pumping board, and this annular region is divided into the charing thorax on top and the cooling thorax of bottom; Many inflammable gas return lines are set, and an end is connected on the sidewall on charing thorax top, and the other end passes into combustion chamber via the pumping board below.
Produce high temperature by biomass burning material and inflammable gas in the described combustion chamber; Load the charing biological material in the described charing thorax, the heat that relies on combustion chamber to produce carries out charing by interior thorax wall conduction; Described inflammable gas return line imports combustion chamber with the inflammable gas that produces in the biological material carbonization process in the charing thorax, and burning produces heat.
The bottom of described pumping board arranges many reinforcing bars, to increase the intensity of pumping board.
The quantity of described inflammable gas return line is the 3-6 root, and a tar receiving trap is set below every inflammable gas return line.
The present invention has the following advantages:
1) utilizes the energy of biomass own, avoid the utilization of fossil energy, low-carbon emission.
2) inflammable gas is recycled, heat utilization ratio is high, reduces the pollution to atmospheric environment.
3) charing and cooling integration design, safety, efficient.
4) simplicity of design, cost is low, and is removable, and the comprehensive utilization ratio of energy is high.

Embodiment
The invention provides a kind of self-combustion biomass char production furnace, the present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this production stove is cylindrical, highly is 1800mm.Arranging with what produce the stove arranged concentric in this production stove is the inwall 3 that the steel plate of 3mm is made by thickness, and inwall 3 is take interior part as combustion chamber 1; The middle part of the annular region between inwall 3 and production furnace outer wall arranges pumping board 6, and this annular region is divided into the charing thorax 2 on top and the cooling thorax 5 of bottom.For increasing the intensity of pumping board 6, the reinforcing bar of pad 2-4 root diameter 10mm below pumping board.The height of described combustion chamber and charing thorax is 1000mm, combustion chamber diameter 150mm, and charing thorax diameter 250mm, the height of cooling thorax is 500mm.Arrange 3 along producing the equally distributed inflammable gas return line 4 of stove furnace wall circumferential direction, one end is connected on the sidewall on charing thorax 2 tops, the other end passes in the combustion chamber 1 via pumping board 5 belows, and a tar receiving trap is set below every inflammable gas return line 4, to prevent line clogging.In the bottom that produces stove 3 in the circumferential direction of the circle equally distributed feets are set, it highly is 300mm.Charing thorax outer wall is selected lagging material, efficiently to utilize heat.Cooling thorax outer wall is selected the good steel plate of thermal conductivity, is beneficial to heat loss, reduces cooling time.
During work, produce high temperature by biomass burning material and inflammable gas in the combustion chamber 1; Charing thorax 2 interior filling charing biological materials, the heat that relies on combustion chamber to produce carries out charing by the inwall conduction; Inflammable gas return line 4 imports combustion chamber with the inflammable gas that produces in the biological material carbonization process in the charing thorax, and burning produces heat.The heat in exit, combustion chamber top can be used for heating cold water.
After charing is finished, high for preventing the biomass char temperature, meet the oxygen easy firing, cause fire or product loss, be connected by pumping board 6 between design cooling thorax 5 and the charing thorax 2, the biomass char of high temperature directly falls into the cooling thorax, under oxygen free condition, cool off, safe and convenient.
