Description
Technical field
The utility model relates to a kind of biomass gas-carbon cogeneration producer, and especially a kind of normalizing and back run biomass gas-carbon cogeneration producer belongs to energy regeneration and utilizes technical field.
Background technology
Biomass generally include agriculture and forestry organic waste materials such as stalk, fuel wood, rice husk, shell.These biomass are carried out rational processing and utilizing, not only help environment protection, can also obtain the valuable energy.Therefore caused people's attention.
Traditional biomass treatment method is boiling type burning, is about to carry out incomplete combustion in the facility that biomass place producer and so on, thereby produces inflammable gas and charing material such as utilizable carbon monoxide.Boiling type incendiary shortcoming is to cross combustion easily.By updating, the normalizing producer of branch grate firing has appearred realizing.The constitutional features of this producer is that oxygen flow enters from the biomass bottom, passes through biomass from bottom to top, and its blast is lower than the gross weight of biomass, so biomass can, burnt prosperous do not seethe with excitement excessive because of combustion air current.Its advantage is to control required incomplete combustion easily, the fuel gases calorific value of gasification intensity and generation is all than higher, its shortcoming be the combustion gas that generates not only temperature is higher but also contain more ash content, need cooling to clean and handle, the result has expended water resources, also can cause secondary pollution.
Retrieval finds, application number is that 200510040840.1 Chinese patent application discloses a kind of back fire-biomass carbonated gas method for generation, and the producer constructional feature that realizes this method is that combustion air current enters from biomass top, passes through biomass from top to bottom.Because combustion air current has restraining effect to ash content, the combustion gas that therefore this method produces need not be cleaned processing usually, but its biological fuel gas and the biomass carbonated product of generation.Back fire-biomass carbonated gas generating stove, the fuel gases calorific value of its gasification intensity and generation are often not as good as the normalizing genetic method.
The utility model content
The purpose of this utility model is: at shortcoming or the deficiency that above-mentioned prior art exists, propose the fuel gases calorific value height of a kind of gasification intensity and generation and need not to cool off and clean the normalizing and back run biomass gas-carbon cogeneration producer of handling.
In order to reach above purpose, normalizing and back run biomass gas-carbon cogeneration producer of the present utility model comprises vapourizing furnace and coking chamber (or claiming the destructive distillation chamber); The top of described vapourizing furnace is anti-internal heat burner hearth, and the bottom is the normalizing gasification hearth; Described anti-internal heat burner hearth bottom sees through being communicated with of anti-stove row and normalizing gasification hearth; The normalizing fire grate of described normalizing gasification hearth bottom has ash output hole and inlet mouth; Described normalizing gasification hearth and coking chamber are close to, and are communicated with coking chamber through passage; The charing fire grate of described coking chamber bottom has carbon outleting port and air outlet; The external gas blower of the inlet mouth of described normalizing gasification hearth, the external vacuum fan in the air outlet of described coking chamber.
During use, utilize the method for biomass gas-carbon cogeneration may further comprise the steps:
The first step, biomass are added anti-internal heat burner hearth, normalizing gasification hearth and coking chamber respectively;
Second goes on foot, lights the biomass in normalizing gasification hearth and the anti-internal heat burner hearth;
The 3rd step, startup gas blower and vacuum fan, the inflammable gas that anti-internal heat burner hearth is produced see through anti-stove row, and the inflammable gas that produces with the normalizing gasification hearth mixes, and enters coking chamber by passage;
The 4th step, extract the inflammable gas that sees through the coking chamber endogenous substance, be transported to required place by the air outlet of coking chamber;
The 5th step, treat the charing of coking chamber endogenous substance after, the carbon outleting port of opening coking chamber takes out.
In the said process, the air quantity by regulation and control gas blower and vacuum fan should be controlled at the temperature of combustion in the anti-internal heat burner hearth 300-400 ℃, and the temperature of combustion of positive and negative internal heat burner hearth is controlled at 400-500 ℃.
In the said process of the present utility model, because normalizing and reverse fire combustion are organically combined, therefore be able to improve the gasification intensity and the calorific value of anti-fiery inflammable gas, suppress the normalizing incendiary impetus by anti-fiery inflammable gas simultaneously, avoid occurring the combustion of crossing that Boiling Combustion causes by positive fire burns; In addition, said process is by the coking chamber endogenous substance, makes mixed positive and negative fiery inflammable gas obtain filtering and cooling, and biomass this in this process by charing; As a result, both obtain satisfactory high heating value inflammable gas, can obtain to replace the charing material of charcoal again.This shows the very rational utility model purpose that realized of technique scheme.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of a preferred embodiment of the utility model.
