Description
Technical field
The technology that the present invention relates to a kind of carbonizing kiln and produce charcoal, specifically a kind of technology of producing charcoal with open quick carbonizing kiln.
Background technology
China is a large agricultural country, all gather in the crops a large amount of agricultural crop straws every year, these stalks or as feed or act as a fuel, especially be many with farmers''s fuel, even some area simply the results time large-area stalk is once burned the field in, the thick smoke of crop straw burning causes the pollution to atmospheric layer and environment, directly influences the traffic on aerial and land.For example, the wheat harvest time in 2006, the domestic big area in Hebei is burned wheat straw, the Capital Airport is taken off had a strong impact on.For this reason Chinese biological mass-energy science and technology forum can on have the scholar to propose: the biomass energy industrialization development should become the new power of China's energy sustainable development.Biomass energy is continue the fourth-largest energy outside coal, oil, the Sweet natural gas of the whole world.Therefore, no matter from ecological view still from point of view of environment protection, all be an extremely urgent big problem to the research of biomass energy charing and utilization.Also occurred about the report to straw charring device and straw charring technology at present, these devices and technology have following defective:
Worm propeller.Because biomass natures quality is fluffy, density is too small, it is biomass resource to be pulverized after the oven dry through high temperature, height be pressed into charing again behind the plug that existing screw rod advances compressor, per hour 150 kilograms, and 20 kilowatts of per hour energy consumptions per ton, energy consumption is big, efficient is low.And work diel must keep in repair once, turnout is low, the parts consumption is big.
Charring process.The existing charring process of smouldering, dry distillation charring technology, the production cycle is long and carbon content product is low, and yield is low.Directly cause the secondary pollution of cigarette, gas, tar in the production process.
Summary of the invention
Goal of the invention one of the present invention is at worm propeller energy consumption height, inefficient defective, provides that a kind of energy consumption is low, the open quick carbonizing kiln of high efficiency.The 2nd, at smouldering charring process and dry distillation charring explained hereafter cycle long, the deficiency of the low contaminate environment of product carbon content provides a kind of with short production cycle, product carbon content height, the fast charring technology of environment-friendly high-efficiency.
Realize the foregoing invention purpose by the following technical solutions:
A kind of open quick carbonizing kiln, comprise the carbonizing kiln body, it is characterized in that, carbonizing kiln body 7 usefulness connecting tubes 15,26 are connected with the tripping device condenser 8 in the outside that is positioned at carbonizing kiln body 7, tripping device condenser 8 is connected with the induced draft fan 10 usefulness connecting tubes 12 that are arranged on the external side of kiln, the bottom of described condenser 8 is provided with recirculated water feedwater piping 19,20, and top is provided with recirculated water drainage pipeline 9,6.One side lower part of described condenser 8 is provided with straw acetum launder 21, the below of this stalk acetate solution chute 21 is provided with the stalk acetate solution storage pool 22 that stores stalk acetate solution body and function, the opposite side of described condenser 8 is provided with the stalk tar chute 18 that is communicated with induced draft fan 10, and the below of this stalk tar chute 18 is provided with stalk tar storage pool 17; Described induced draft fan 10 usefulness connecting tubes 2 are connected with gas storage device 3; The bottom that kiln body floss hole 27 is positioned at the kiln body is connected with condenser 8 usefulness connecting tubes 15, the temperature indicator 4 that detected temperatures is used is installed in the outside of carbonizing kiln body 7, it is external that circulating water pool 1 is arranged on carbonizing kiln, and temperature test probe 11,14,24,25 is installed in respectively on intravital four angles of carbonizing kiln.
A kind of technology of producing charcoal with open quick carbonizing kiln, comprise the material plant stalk rolled and cut, pulverize, dry, the straw raw material of packing in the carbonizing kiln body, its production technique also comprise the following steps, raw material that will be through pulverizing oven dry is with being compressed into the biomass type piece; The biomass type piece is changed in the open quick carbonizing kiln, and sparking mode is lighted raw material in the employing, when temperature reaches 190 ℃, carries out the disconnected oxygen of raw material under physical environment, and the raw material charing in the kiln was lowered the temperature after 6～8 hours; With recirculated water valve and the red-tape operati of temperature control display instrument, produce unformed charcoal piece.
Owing to adopt technique scheme, to compare with background technology, the open type carbonizing kiln is provided with flue and waste liquid, waste residue storage pool, and whole process of production does not have waste gas, waste liquid and waste sludge discharge, the protection environment.And having the characteristics of heat insulation air heating, oxygen and a nitrogen content are few in the combustion gas, the fuel gases calorific value height.Can produce multiple product simultaneously with this device technique technology, stalk powdered carbon, stalk tar, stalk vinegar liquid, various products all have very high commercial value.The stalk inflammable gas can be recycled, and acts as a fuel, and benefits the common people.Also contain carbonic acid gas in the gas, can extract manufacturing dry ice.Common powdered carbon can be made into intermediate charcoal, senior charcoal through after dark, the precision work, and its purposes is extremely extensive.
The quick carbonizing kiln production technique, sparking mode is lighted raw material in the employing, and self-produced combustion gas is a thermal source, carries out the disconnected oxygen of raw material when temperature reaches under physical environment, makes the rapid charing of raw material in the kiln.Every kiln can add 3 tons of biomass type pieces, produces unformed charcoal piece, its full scale production process, and by recirculated water valve and the red-tape operati of temperature control display instrument, technological process is simple, has stopped the generation of living charcoal and charcoal ash, product qualification rate reaching 99%.
