Description

A kind of dump grate device of refuse pyrolysis gasification furnace
Technical field
The present invention relates to technical field of waste treatment, in particular to a kind of dump grate device of refuse pyrolysis gasification furnace.
Background technique
As process of modernization constantly accelerates, crude waste waste discharge capacity is growing day by day, traditional garbage disposal Method causes serious soil and atmosphere pollution, it is difficult to adapt to sustainable development, rubbish is often used in current many garbage disposals Rubbish pyrolysis gasifying device carries out pyrolysis and carbonization at low temperature gasification to it, makes organic matter using the thermal instability of organic matter in garbage The process that cracking forms various new fuel gas is generated, it is more environmentally-friendly compared to incineration method, realize that sustainable energy utilizes.But mesh The refuse pyrolysis gasification installation of preceding mainstream in the market is primarily present following disadvantage:
Drying structure, it is traditional one is being dried in furnace, one is the drum-type drying equipment of pretreating zone, dried in furnace The shortcomings that be that the refuse gasification time is slow, and after rubbish enters in furnace, as the temperature rises, and a large amount of vapor generates, meeting The combustible gas of refuse pyrolysis generation is diluted, the temperature of dual firing chamber is caused to decline.And drum-type drying equipment because be hot wind into Collet drying is dried rubbish through steel plate, is not contacted directly with rubbish, and drying efficiency is low, and thermal losses is very big, and dries The operating cost of equipment is also big, and landfill leachate also bad processing.
It slags tap structure, every suit incinerator requires to slag tap, and manually slags tap from initial to current rotary fire grate, machine Tool fire grate is slagged tap mode, and risk of manually slagging tap is big, and the feature of environmental protection is poor, and rotary fire grate, which is slagged tap, or stoker fired grate is slagged tap has investment Greatly, corollary equipment is more, the high problem of operating cost.Because the continuous operation of slag-tapping system, there is also do not burn for traditional slag-tapping system The phenomenon that saturating slag comes out, and bulk clinker is but unable to come down lives slag notch by water seal when due to slagging tap and realizes sealing, and clinker falls In puddle, vapor is big in workshop, and stink is big, and sewage, sludge are difficult, be easy to cause secondary pollution.
Fire grate is the main component of pyrolysis gasification furnace, but the fire grate currently used for pyrolysis gasification furnace it is generally existing manufacture at This height, the problem of cannot supplying oxygen to burning, although some increase some improvement in functionality, manufacture is again very complicated.
Feed intake structure, and conventionally employed is open type charging, even if some occasions are in security consideration and also take closing Charging, but still without solving sealing problem, air is had while charging or work and enters pyrolysis gasification furnace, is caused non-negative Work is pressed, has smoke spillage during pyrolytic gasification, affects pyrolytic gasification effect, also have gas explosion sometimes.
Fire observation device, common fire observation device is usually by flame-observing hole transparent cover cap, asbestos rubber pad, pyroceram piece, sight fire The composition such as hole pipe has an other burner glass surface of seeing in order to prevent to cover tar, dust, has installed baffle additional.Disadvantage: (1) dust protection baffle influences observation sight.Dust protection baffle is typically all to be mounted on the center for seeing fire tube, affects observation Sight.(2) without provision for thermal insulation, the generation of safety accident is easily led to.Seeing fire tube is directly protruding into kiln, usually selection metal material Material production, it is thermally conductive fast, entire fire observation device can be made to form high temperature, be easy to cause in the use processes such as observation, replacement glass boiling hot Hurt safety accident.(3) it is narrow to see fiery visual angle.Sight fire tube is straight tube structure, so that seeing, fiery visual angle is narrow, and the range for seeing fire is small.
External air flue, the common typically no independent gas flue of gasification furnace, is all air-introduced machine under the action of air-introduced machine, directly The gasification layer from rubbish is connect, extracts gasification furnace out by each layer of rubbish.Also a small amount of gasification furnace sets built-in air flue, but due to It is influenced to will cause flue gas by in-furnace temperature to burn in gasification furnace, affects gasification result, while built-in air flue also affects The working conditions such as spice of the rubbish in gasification furnace.Shortcoming and defect: (1) flow of flue gas speed is slow.Due to by gasification layer upper layer The influence of rubbish stacking pressure causes flue gas discharge to be obstructed, circulates unsmooth, draw speed is slow.(2) gasification efficiency is low.Due to flue gas stream Lead to unsmooth, flowing velocity is slow, some has just been burned off the combustible gas for causing to gasify out in gasification furnace, causes simultaneously The in-furnace temperature that gasifies is excessively high, causes adverse effect to gasification result.(3) fume treatment effect is influenced, by flow of flue gas speed Slowly, the low influence of gasification efficiency, the flammable tolerance that flue gas enters combustion chamber is inadequate, causes chamber temperature too low, has in flue gas Evil ingredient cannot be destroyed, and influence the effect of fume treatment.
Summary of the invention
According to an aspect of the invention, there is provided a kind of dump grate device of refuse pyrolysis gasification furnace, including successively Circulation connected drying unit, fan house, pyrolysis gasification furnace, dual firing chamber and heat exchanger,
Pyrolysis gasification furnace includes fire grate device, and fire grate device is horizontally placed on the middle part of burner hearth, fire grate device include fire grate, Fire grate axis, driving unit and cooling unit, fire grate are arranged in parallel to be multiple, and cooling unit includes cooling water inlet pipe and cooling water outlet Pipe, fire grate are located on fire grate axis, and driving unit is connected with fire grate axis, and fire grate is equipped with multiple air ventilation holes.It is beneficial to effect Fruit is that fire grate is installed on pyrolysis gasification furnace burning position bottom, and bearing is installed at two ends, the rotation support as fire grate overturning.Furnace It arranges axis and uses hollow structure, water receiving pipe in parallel therebetween cools down fire grate by cooling water, to protect fire grate, fire grate axis axis Hold to work normally at high temperature.Fire grate ontology working face designs multiple air ventilation holes, is used for air air feed.Fire grate shaft end peace Driving device is filled, fire grate rotary work is driven.Fire grate is installed on pyrolysis gasification furnace burning position bottom, conduct when fire grate is failure to actuate Fire grate uses.Design has air ventilation holes on fire grate, and gasification furnace First air, to fire grate lower section, passes through air draught by blower air feed Hole carries out air feed to burning, and oxygen needed for providing burning, volume of air supply is adjusted by the control indoor blower of blower.It needs When slagging tap, by driving device driving fire grate rotation, lime-ash is fallen.
In some embodiments, the driving unit of fire grate device includes bearing, gear, rack gear, oil cylinder and cylinder bracket, The oil cylinder is located on cylinder bracket, and the oil cylinder drive rack drives the rotation of the gear, and the gear drives the axis The rotation held, the bearing drive the overturning of the fire grate axis, and fire grate axis drives fire grate rotation, adjacent fire grate direction of rotation phase Instead.The beneficial effect is that two adjacent fire grate reverse turns are conducive to attrition crushing clinker and facilitate discharge.
