mAP MIX PROVECTUS gas mixer product, or adopt the disclosed three component distribution static mixing air distributing devices of Suzhou Sheng Yu gas apparatus company limited, its principle is can will be as: the gases such as propane, hydrogen and nitrogen are through variable valve, and under meter adds in mixing tank; Control the flow of propane, hydrogen and nitrogen, and reach the function of adjustments of gas blending ratio, gas mixture evenly mixes through mixing tank, and qualified gas is delivered to place to use by exit from do valve.Three component distribution static mixing air distributing device equipment characteristics: three grades of decompression voltage regulation functions, import depressurized system, the clear demonstration unstripped gas of direct-reading flowmeter ratio, setting device meets the mixture requirement of different tests gas arbitrarily.Vertical shaft furnace is with air intlet, one outlet (only export but no import) of hot gas mixed allocation chamber 17 communicates with the heating chamber 9 that the rotating cylinder of charing section part is provided with outward through entering heating chamber regulating gate 18, another import (can only enter and can not go out) of hot gas mixed allocation chamber is connected with the exhaust pipe of biomass boiler, another outlet (can only enter and can not go out) of hot gas mixed allocation chamber 17 is through flue, tail gas mixing gate 19 is communicated with tail gas mixed allocation chamber 20, tail gas mixed allocation cell structure is identical with hot gas mixed allocation chamber, tail gas mixed allocation chamber 20 is located at heating chamber 9 front portions and is communicated with heating chamber, converter diffuser 21 is arranged in charing section front portion, converter diffuser is the six-way valve that has four inlet mouths and two air outlets, its structure is the check valve that is provided with only import but no export in four inlet mouths, and in two air outlets, be provided with the check valve of only export but no import, four inlet mouths of converter diffuser are arranged in tail gas mixed allocation chamber and communicate with tail gas mixed allocation chamber, an air outlet in two air outlets of converter diffuser communicates with drying section, another air outlet communicates with charing section.Be provided with burner induced draft fan 22 at burner and be connected with burner dust collecting cabinet, burner dust collecting cabinet (gathering the cupboard of dust), burner dust collecting cabinet is connected with the drying section part 6 of the burner of rotating cylinder.
Principle of work: motor and the transmission rig thereof of first driving rotating cylinder rotate rotating cylinder, start again burner induced draft fan and stove tail induced draft fan, bamboo wood chip send drying section part in rotating cylinder to, charing section front portion enters charing section part, first use external heating mode (as the modes such as electrically heated are set) to allow heating chamber be heated to 400-700 DEG C, the charing section part of the temperature action of heating chamber in rotating cylinder makes to be arranged in the bamboo wood chip pyrolysis charring of charing section part, and the carbonization product after charing is through the cabinet 11 that gathers materials, the discharging of cooling spiral device.The pyrolysis combustible gas (high temperature) producing after bamboo wood chip pyrolysis charring is through the charing pyrolysis gas outlet at the top of the cabinet that gathers materials, pipeline, cyclonic separator enters stove tail induced draft fan 15, a part is sent vertical shaft furnace 16 to and is joined oxygen burning, redundance is sent biomass boiler combustion chambers burn to, the high temperature hot gas (now hot gas generally has 800-1200 DEG C) that vertical shaft furnace is joined oxygen burning enters hot gas mixed allocation chamber 17, point distribution that tail gas after biomass boiler burning also enters after the mixing temperature adjustment of hot gas mixed allocation chamber (generally can furnishing 400-700 DEG C hot gas) enters through entering heating chamber regulating gate in the heating chamber 9 that the rotating cylinder of charing section part is provided with outward, wherein there is a part point distribution also to enter the interior heat pipe 8 in charing section, its strengthening heating charing section effect, the flight that rotating cylinder inwall is installed or radiator element play the effect of strengthening heating charing section, point distribution now entering in heating chamber is entered from the inlet end of interior heat pipe, then out also enter tail gas mixed allocation chamber from its outlet side, the wherein outer cylinder body of another part point distribution heated drums, the tail gas after heating enters in tail gas mixed allocation chamber, point distribution after hot gas mixed allocation chamber mixing temperature adjustment (generally can furnishing 400-700 DEG C) is again by another flue, tail gas mixing gate enters in tail gas mixed allocation chamber 20, playing secondary temperature adjustment makes the temperature in tail gas mixed allocation chamber rise to 300-600 DEG C, under the induced air negative-pressure effect of burner induced draft fan 22 and stove tail induced draft fan 15, make generation negative pressure in rotating cylinder, then point distribution after the temperature adjustment in tail gas mixed allocation chamber enters in rotating cylinder through four inlet mouths of converter diffuser 21, point distribution part entering after the temperature adjustment after rotating cylinder enters drying section part and dries bamboo wood chip, tail gas after oven dry is through burner dust collecting cabinet, emptying through burner induced draft fan again, a point distribution after another part temperature adjustment enters charing section part heats in many charing sections again, and the interior external heat that forms charing section of the present invention has both, and has triple heating functions.The cabinet place that gathers materials at burner dust collecting cabinet and stove tail is respectively provided with vacuum table 23, its objective is the hot gas amount for regulating and controlling to distribute charing section part and drying section part, and the pyrolysis gas of guaranteeing charing section part all flows to stove tail, enter stove tail induced draft fan through the outlet of charing pyrolysis gas, pipeline, the cyclonic separator at the top of the cabinet that gathers materials.The present invention, in the time that the vacuum table pressure of dust collecting cabinet is excessive, will reduce the draft of burner induced draft fan air inducing, so just can meet effective control that in the rotating cylinder of whole system, temperature and tolerance flow to.
Thermometer is installed in the place that need to control temperature at each, as: thermometer 24 is all installed before, during and after heating chamber, also in vertical shaft furnace, the cabinet that gathers materials, dust collecting cabinet, hot gas mixed allocation chamber, tail gas mixed allocation chamber etc., thermometer is all installed, to control better the temperature of each vitals etc.
Effective control of the tolerance in the rotating cylinder of whole system is by burner induced draft fan, stove tail induced draft fan, enter heating chamber regulating gate, tail gas mixing gate is controlled.
An object controlling like this tolerance and temperature is: make the temperature of charing section part and drying section part remain comparatively high temps, wood tar oil can coolingly not stick on rotating cylinder, pipeline and fan blade etc., avoid introduction pipe and drawn blower fan because of the blockage problem that the cooling adhesion of wood tar oil causes, having ensured the stability of producing.
