Abstract
The utility model relates to a straw gas generator. A furnace body 16 which is in a casing 17 is provided with a gas outlet 12, waste heat recovery heating system 8, a discharging tube 7, a sensing thermometer 13, a feeding system 22, a preheating material inlet pipe 4, and a distribution awl 3 from top to bottom. Air is introduced into the waste heat recovery heating system from the upper part of the furnace body, and after heated, the air is introduced into a furnace chamber 18 from the outer side of the casing and through the bottom of the furnace body. Particles such as straw is conveyed into the furnace chamber through the feeding system 22, under the action of air flow of hot air which is introduced from the bottom, the straw materials are in a fluidized state, the incomplete combustion of the straw materials is carried out, and thereby, straw gas is generated. The gas is collected from the gas outlet 12 at the upper part, and can be used by users. The utility model has the advantages of economy, practicality, and high gas production quantity.
Description
The utility model is a kind of producer that utilizes material production straw coal gas such as straw, is to belong to the producer gas generator series product.
At present, also more and more higher to energy demand along with the raising of living standards of the people, requirement is also increasing.The city resident generally uses Sweet natural gas and coal gas, and the rural area is also brought into use, but not general, straw or coal still burn in a large amount of peasant households, and energy utilization rate is low, pollution is big, and a considerable amount of straws are arranged with not falling, just between the edge of a field ground, set fire and burn, form waste greatly, and cause bigger pollution.
The novel purpose of this reality provides a kind of straw producer gas generator, it can utilize material production high-quality straw coal gas such as a large amount of straw in rural area, yule logs, paper scrap, wood chip, use for vast rural area and samll cities and towns, can make full use of fuel, save energy, minimizing pollution, this equipment is economical and practical, the gas production rate height is particularly suitable for vast rural area and samll cities and towns and uses.
The technical solution of the utility model is: body of heater 16 is installed in the housing 17, fill up flame-proof thermal insulation material 19 between body of heater and the housing, be used for furnace insulation, improve the thermo-efficiency of body of heater, straw coal gas air outlet 12 is equipped with at the body of heater top, upper of furnace body is equipped with waste heat recovery heating system 8, this heating system is by inlet pipe 10, regulated valve 11, double-layer coil tube 9 and airway 1 are formed, regulated valve 11 is housed on the inlet pipe 10, inlet pipe enter after by housing in the middle of the burner hearth 18 of body of heater 16 and and burner hearth in double-layer coil tube 9 link and communicate, another outlet side of double-layer coil tube and stretch into airway in the burner hearth and link and communicate, airway leads to the body of heater bottom after by furnace body shell and feeds the body of heater from the body of heater bottom outside housing, also available single or multiple lift coil pipe replacement double-layer coil tube except that double-layer coil tube.The air that enters body of heater mainly enters from inlet pipe, enters the burner hearth from bottom of furnace body through airway after the double-layer coil tube heating again, and the air capacity that enters body of heater can be controlled by regulated valve, and the oxygen level that enters the air in the body of heater is also done suitable control.Drainage conduit 7 is equipped with in body of heater 16 middle and lower parts, drainage conduit one end by housing after and the burner hearth of body of heater link and communicate, the other end communicates with the external hopper 6 of housing.Feed system 22 is equipped with in the body of heater bottom, this system is made up of screw auger 20, shaft coupling 23, electromagnetic adjustable speed motor 24 and hopper 21, burner hearth direct and body of heater linked after the screw auger exit end passed housing, the screw auger the other end links by shaft coupling and electromagnetic adjustable speed motor, and hopper 21 is equipped with in top, auger rear portion.Materials such as straw enter auger through hopper, are sent in the burner hearth by auger under the drive of motor, and straw inlet amount and speed can realize by the speed of regulating motor.Be equipped with on the feed system 22 below bodies of heater and give heating material inlet pipe 4, this inlet pipe is by in the straight-through burner hearth behind the housing, fuel such as the first timber of blow-on are sent into burner hearth by this inlet pipe body of heater are carried out heat temperature raising, reach in furnace temperature and to stop to send into fuel when 700-800 spends, send into the materials such as straw that coal gas takes place this moment by auger.This inlet pipe 4 can be used as the situation that inspection window 5 checks that at any time burner hearth is interior during not charging at ordinary times.Give the awl 3 that distributes is housed in the middle of the heating material inlet pipe 4 below burner hearths, this awl that distributes is upper/lower cone shape structure, and the space of a 4-6mm is arranged between it and the furnace body wall, and the awl that distributes is fixed on the wall of burner hearth by three support plates 2.The air that airway enters the body of heater bottom enters upper furnace by the awl that distributes.The body of heater upper, middle and lower were provided with sensing temperature meter 13 in 3 years, and each thermometer all is connected with a display screen 15 by lead 14, by observing the temperature at each point place in the body of heater on the display screen at any time.In the utility model when work, sent into fuel such as timber to the burner hearth internal heating by giving the heating inlet pipe earlier, send into air from inlet pipe simultaneously, timber is fully burnt, when treating that stove Nei Wenduda 700-800 spends, stop to send into fuel such as timber, send to through the coal gas such as straw that are ground into certain fineness from feed system this moment and expect, the air quantity that control simultaneously enters, this air is through inlet pipe, the double-layer coil tube heating, enter from the body of heater bottom through airway again, the airborne oxygen level that enters is also done certain control, this air upwards forms an impulse force (promptly producing certain air-flow) through the awl that distributes, and this air-flow is blown out fluidized state to the straw that enters, because temperature is higher in the stove, reached more than 700 degree, the straw material of fluidized state can carry out spontaneous firing, and again because the air capacity that enters is limited, and airborne oxygen level is more limited, the burning that makes deposits yields such as straw is an incomplete combustion, produces a large amount of methane (CH during material incomplete combustions such as straw
4), hydrogen (H
2) and carbon monoxide (CO), these gases are exactly straw coal gas, and this coal gas is gone out from coal gas air outlet, body of heater top, just can use for users after collecting, and the remaining ash of burnings such as straw is discharged and is admitted to the groove that connects material from drainage conduit and transports.
The straw producer gas generator of said structure carries out a large amount of fuel such as straw in rural area to produce a large amount of high-quality straw coal gas for vast rural area and samll cities and towns' use behind the incomplete combustion, both made full use of fuel, saved the energy, reduced pollution again, this equipment is economical and practical, gas production rate is high, is particularly suitable for vast rural area and samll cities and towns and uses.
