Abstract
The utility model relates to a pyrolyzing furnace for heating plant stalks to produce gas with moderate calorific value, primarily which is composed of a heating part and a pyrolyzing part. A pyrolyzing furnace body is at the centre of the pyrolyzing part, where a helix feeder is provided, and a loading hopper is connected with one end of the pyrolyzing furnace body through a flapper for a feed inlet while a slag hole is connected with the other end of the pyrolyzing furnace body through a flapper for the slag hole. An air outlet for gas is positioned on the pyrolyzing furnace body at the top part of the slag hole, and an expansion compensator is connected with the slag port of the pyrolyzing furnace body. A high-temperature air flue connected with a burning furnace bundles the pyrolyzing furnace body and a circulating blower fan is arranged between the back end and the anterior part of the high-temperature air flue. The high-temperature air flue is bundled at the middle segment and the feed inlet segment of the pyrolyzing furnace body, and the inlet of the high-temperature air flue is provided with a heating electric resistance thermometer.
Description
The utility model is a kind of equipment that utilizes calorific value of gas in the production of plant straw, belongs to the gas production apparatus technology.
Coal gas is the energy required in industrial production and the daily life, the mode of its production also has many kinds, its overwhelming majority adopts coal as raw material, the raw material that utilizes the plant straw to make gas production is a new technology in recent years, therefore, to the technology of producing, all there are many imperfection parts from its production unit.Its patent is to be " 96223644.6 " " to be produced the equipment of inflammable gas by the plant stalk crushed material " as state-of-the-art technology, has a large amount of problems in actual motion, and its main drawback is: 1. thermo-efficiency is low, approximately has only about 50%, and a large amount of energy are wasted.2. easily cracking is stirred the cage scaling loss.Owing to be directly to burn heating pyrolyze to stir cage with coal, this stirs cage is to make with the heat-stable stainless steel of carbon steel outsourcing, flame directly contacts stainless material, causes this equipment not move several days and the problem that the distortion of cage scaling loss is stirred in cracking will occur, has a strong impact on safe and continuous fortune and stops.3. temperature compensation equipment is not set.
The purpose of this utility model just provides a kind of thermo-efficiency height, economic and reliable, the plant straw pyrolysis oven of producing middle calorific value of gas of energy safe and continuous operation.
The plant straw pyrolysis oven of calorific value of gas is mainly by roasting kiln, high-temperature flue, screw feeder, slag notch, slag notch air locking device in of the present utility model the producing, expansion compensator, coal gas air outlet, exhanst gas outlet, loading hopper, the opening for feed air locking device, transmitting gear, recirculation blower, thermal resistance thermometer is formed.The pyrolysis part is the center with the pyrolysis body of heater, screw feeder is arranged in the pyrolysis body of heater, loading hopper is connected with an end of pyrolysis body of heater by the opening for feed air locking device, slag notch is connected by the other end of slag notch air locking device with the pyrolysis body of heater, the coal gas air outlet is positioned on the pyrolysis body of heater on slag notch top, and expansion compensator is connected with the discharging port of pyrolysis body of heater, high-temperature flue parcel pyrolysis body of heater, roasting kiln is communicated with high-temperature flue, is provided with recirculation blower between the rear end of high-temperature flue and front end.High-temperature flue is wrapped in the stage casing of pyrolysis body of heater to the opening for feed section.Ingress at high-temperature flue is provided with a thermal resistance thermometer.Its working process is.
Add the pyrolysis body of heater from loading hopper after the plant stalk fragmentation, through screw feeder the plant straw is fed forward, the flow direction of plant straw and flue gas adopts adverse current, and flue gas is outside pipe, and straw is in pipe, the straw that enters the pyrolysis body of heater at first carries out preheating with the heat of the flue gas that is about to discharge flue by the tube wall transmission, along with the propelling of screw feeder, the temperature of straw raises gradually in the pipe, when reaching pyrolysis temperature, produce combustible coal gas, remaining residue is discharged by slag notch.When the flue-gas temperature of high-temperature flue surpasses the heat resisting temperature of pyrolysis body of heater, start recirculation blower, flue gas is sucked recirculation blower to be sent into the high-temperature flue gas that mixing section and roasting kiln produce and mixes, make the external flue-gas temperature of pyrolysis oven can not cause the overheated scaling loss of pyrolysis body of heater tube wall, move with the safe and continuous of guaranteeing pyrolysis oven.
Advantage of the present utility model is:
1. thermo-efficiency height.Plant straw and high-temperature flue gas adopt reflux type, and heat transfer temperature difference is big, and waste heat is used for pre-thermal material, and funnel temperature is reduced, and make thermo-efficiency reach more than 70%, have not only improved production efficiency.Also obviously improved simultaneously the economic benefit of producing.
2. safe and reliable to operation.Adopt the burning of peripheral hardware burner hearth, and effectively control the external flue-gas temperature of pyrolysis oven, guarantee that the tube wall of pyrolysis body of heater can be by scaling loss, strong assurance the long-term safety operation of equipment, improved work-ing life simultaneously.
3. owing to be provided with expansion compensator, the equipment failure that the thermal expansion factor causes has been eliminated in the termination that is added in the pyrolysis body of heater.
Fig. 1 is an overall structure synoptic diagram of the present utility model.Comprising: roasting kiln 1, high-temperature flue 2, screw feeder 3, slag notch 4, the air locking device 4-1 of slagging tap, expansion compensator 5, coal gas air outlet 6, exhanst gas outlet 7, loading hopper 8, opening for feed air locking device 9, transmitting gear 10, recirculation blower 11, thermal resistance thermometer 12.
Embodiment of the present utility model is as follows:
The pipe shape that pyrolysis body of heater 3-1 is made for stainless steel, be provided with the screw feeder 3 that stainless material is made therebetween, end at the pyrolysis body of heater is provided with the expansion compensator 5 that stainless material is made, the other end sealing, screw feeder 3 pass sealing termination transmitting gear 10, are being provided with on the pyrolysis body of heater on the side of expansion compensator 5 one ends, top is provided with coal gas air outlet 6, the bottom is provided with slag notch 4, is provided with the slag notch air locking device on slag notch 4, pours in to prevent air.Top, the other end side at pyrolysis oven is provided with loading hopper 8, is provided with the opening for feed air locking device between loading hopper 8 and pyrolysis body of heater 3-1, pours in to prevent air.Roasting kiln 1 adopts the mode of peripheral hardware stove hall to heat the pyrolysis body of heater.In order to raise the efficiency, plant straw and flue gas adopt the mode of adverse current, and high-temperature flue 2 is drawn by roasting kiln 1, and the middle part of this flue wraps the pyrolysis body of heater, the inlet mouth of high-temperature flue is positioned at the middle part of pyrolysis body of heater, and the exhanst gas outlet 7 of high-temperature flue is positioned at charging opening one side of pyrolysis body of heater.Damage body of heater in order to prevent that the pyrolysis stove body temperature is too high, be provided with a thermal resistance thermometer 12 and recirculation blower 11 on high-temperature flue, the inlet mouth of recirculation blower is connected with the exhanst gas outlet of high-temperature flue one end.The air outlet of recirculation blower connects import one end of high-temperature flue, thermal resistance thermometer also is located at this place, when high-temperature flue gas surpasses the temperature rating of pyrolysis body of heater, starts recirculation blower, make and enter the safety that the external flue-gas temperature of pyrolysis oven can overrate not be guaranteed pyrolysis oven, operation continuously.
