Abstract

A cracking and slag draining device for fuel produced by organic refuses is composed of a pipe cracking furnace, a material slag draining device, an electric heater unit and a drive and control device. The tube cracking furnace mainly consists of a collector and transporting tubebanks at two sides. The transporting tubebanks are linked at two sides of the collector in parallel. Each tubebank independently transports materials and the transporting terminal of which is abutted with the collector. An air outlet on the collector corresponds to the transporting tubebank and is communicated with the slag draining device. The collector collecting tube is installed with an electric heater and provided with a transporting hinge at lower. The tube cracking furnace solves the problems in the kettle thick tube hot feed process, has the advantages of uniform heating, continuous production operation, organic refuse processing amount 60-90 T each day and more than 50% of recovery rate. The slag draining device has high strength, no dead angle for transporting materials, no residues and small device volume and safe production and low replacement frequency of the device and parts and avoids local overheat and device deformation due to scale formation and coke.

Description

Organic waste is made fuel cracking slag discharging device

Technical field

The utility model relates to refuse treatment plant, particularly reclaims organic waste and produces the cracking slag discharging device that fuel is used.

Background technology

The scientific utilization of municipal wastes and harmless treatment are always various countries and pay attention to, and rubbish is improved to recycling by burning landfill, particularly reclaim the organic waste technology and equipment that uses that acts as a fuel and have been seen in report.CN1204227C number " refuse disposal system of derivatived fuel ", this technology at first removes the air in the rubbish material, under vacuum condition, makes at 400～700 ℃ that hot gas flow is reverse to be contacted with material in thermo-cracking light.Carry out thermo-cracking, then by purify and filter fuel gas.Its shortcoming is that technical matters flow process and equipment are loaded down with trivial details, and consumes energy is big; Have only the partial organic substances gas that acts as a fuel to be recovered, gasification part and a small amount of combustion prod do not obtain recycling.In the present already used organic waste recycling equipment, single (slightly) pipe or the still formula heating pyrolyze equipment of adopting more, the production cycle is long, efficient is low, is not suitable for a large amount of organic wastes of handling continuously.Heat as tubular type, a large amount of organic wastes inequality of being heated causes partial occlusion, treatment capacity is big more, caliber is thick more, and obstruction is just serious more, and the fouling of slag charge wall built-up, coking occur now and then in the operational process, cause local superheating, equipment distortion, so that can not the serialization normal operation, this technical barrier is not resolved all the time so far.

Summary of the invention

The utility model purpose is to overcome the deficiency that existing organic waste recycling technology and equipment exists, provide a kind of day and handle organic waste 60T～90T, high and the continuous running job of energy of the rate of recovery, reasonable, the safe recovery organic waste of processing unit is produced the cracking slag discharging device that fuel is used.

Organic waste provided by the utility model is made the cracking slag discharging device that fuel is used, mainly contain the tube cracking furnace [3] that is used for defeated material and thermo-cracking, material slag off apparatus [5], electric heater unit and driving control device, be characterized in that this tube cracking furnace mainly is made of condensing funnel [3-6] and two Jis defeated material tubulations [3-3], defeated material tubulation [3-3] is connected in condensing funnel [3-6] both sides with parallel way, every tubulation independence convey materials and defeated material terminal are docked with condensing funnel, condensing funnel is provided with and the defeated material corresponding pneumatic outlet of tubulation [3-1], this pneumatic outlet is communicated with material slag off apparatus [5], and condensing funnel [3-6] bottom is provided with carries the not conveying hinge dragon [3-4] of gasification materiel.

For continuing to be warming up to the temperature of doing of regulation, further cracking material, the utility model design has the material slag off apparatus [5] that is connected with tube cracking furnace [3], the pneumatic outlet [5-1] that material slag off apparatus [5] is provided with locates to be equipped with catalytic bed, and with separating and reclaiming device UNICOM, gas inlet [5-2] is communicated with the pneumatic outlet [3-1] of tube cracking furnace condensing funnel [3-6], not gasification materiel import [5-3] is communicated with the deslagging outlet of condensing funnel hinge dragon [3-4], tubular type spiral hinge dragon [5-5] is equipped with in slag off apparatus [5] bottom, and residue outlet [5-4] connection-carbonoxide producer carries out the gas deep processing.Material slag off apparatus end face than reasonable structural design is: spiral cuts with scissors imperial pipe and becomes neither isometrical up and down half arc until the periphery design of slag off apparatus, and two halves arc and bottom spiral hinge dragon are spool concentric and connect into symmetrical structure with trapezoidal side plate.

The utility model is compared with existing installation and is had the following advantages:

1, tube cracking furnace has solved present still formula, extra heavy pipe adds the technical barrier in the explained hereafter such as hot feed, be heated evenly clog-free, can realize the continuous production operation, day handle organic waste 60～90T/ day, the rate of recovery reaches more than 50% (gas, liquid fuel occupy machine rubbish per-cent) and utilizes the microcomputer complete monitoring;

2, the tubulation quantity of tube cracking furnace can be set according to output, because caliber and screw diameter are little, torque is little, with compare total capacitance with the miscellaneous equipment of equal yield line and do not increase, but enlarged heat transfer area, improved heat utilization efficiency, reduced equipment investment cost with equal yield line, prolonged service life of equipment, maintain and replace is convenient;

3, condensing funnel in the pyrolyzer and material slag off apparatus adopt the most reasonably project organization, equipment intensity height, convey materials do not have dead angle, no residue, avoided equipment encrustation, coking to cause local superheating, cause the equipment distortion, this equipment volume is little, internal volume is little, material does not stop, moves smooth and easy for a long time, production process safety coefficient height, and equipment and part replacement frequency reduce greatly.
