Description
Technical field
The utility model belongs to technical field of combustion equipment, is specifically related to one way of life rubbish, the biogas of percolate and the incinerator of mud mixed combustion.
Background technology
Along with the high speed development of national economy and the raising day by day of living standards of the people, house refuse and sewage increase rapidly.Percolate be house refuse in stacking process, the free water of the water that the decomposition due to organic matter in garbage produces and rubbish, precipitation and the underground water infiltrated, the high concentrated organic wastewater formed by eluviation.It contains a large amount of harmful substances, if do not add process and directly discharge, can cause serious environmental pollution, therefore carry out process to percolate and be absolutely necessary.In the processing procedure of percolate, a large amount of biogas can be produced.Biogas has higher calorific value, is a kind of available energy.
For protection of the environment, sewage also needs process.And in sewage purification process, will mud be produced.Mud be a kind of between liquid and solid, present the concentrated thing of slurry feature, the aggregate that the zoogloea that it is actual is formed by multiple-microorganism and the organic matter of absorption thereof and inorganic matter form.Be characterized in that content of organics is high, easily corruption produces stench; Particle is tiny, and density is little, and moisture content is high.Along with the raising of wastewater treatment rate, sludge quantity is also on the increase, and the process of mud is extremely urgent.
At present, sludge incineration is a kind of prevailing technology of Treatment of Sludge, and it utilizes incinerator by dewatered sludge heat drying, then uses the organic matter in high-temperature oxydation mud, makes mud become a small amount of lime-ash.Moisture in mud and organic matter can be removed by this processing method completely, and kill pathogen, realize innoxious, minimizing and the resource of Treatment of Sludge substantially.
Even if because mud moisture after dehydration or drying is still more, calorific value is lower, if directly as fuel not easily smooth combustion.Burn for impelling mud timely to fight, the special biogas that adopts is combustion-supporting, the mud of drying and biogas are sprayed in incinerator by specific burner in the lump and burns with domestic garbage mixing, utilize the heat burned to produce steam and be used for steam supply and generating, so not only can turn waste into wealth, economize energy, protection of the environment; There is again good social benefit and considerable economic benefit.Therefore for the biogas of house refuse, percolate and the fuel characteristic of mud, completely newly develop First house refuse, the biogas of percolate and the incinerator of mud mixed combustion.
Utility model content
The purpose of this utility model is design one way of life rubbish, the biogas of percolate and the incinerator of mud mixed combustion.
Realize above-mentioned purpose, the utility model adopts following design:
The biogas of one way of life rubbish, percolate and the incinerator of mud mixed combustion, comprise two sections of reciprocating fire grates, in incinerator above two sections of reciprocating fire grates, hogging is set, in incinerator both sides, methane-sludge combustion combustor is installed, face arch and rear arch are set on incinerator top, and arrange Secondary Air respectively at face arch and rear arch place.
Further, centered by described methane-sludge combustion combustor, Inlet Swirl formula burner, is equipped with swirl vane in its secondary air channel, and first and second air port is with enlarging angle.
Further, described face arch and rear arch are adiabatic chimney arch.
Further, described hogging is water-cooled arch, and is in tilted layout, low after front height.
By adopting such scheme, this real utility model has the following advantages:
1, moisture content low for sludge calorific value this characteristic high, selects the mode of the biogas multifuel combustion of mud and percolate, combustion-supporting by biogas, guarantees that mud catches fire in time, smooth combustion.According to the biogas of house refuse, percolate and the different fuel of these three kinds, mud, adopt mode that two sections of reciprocating fire grates combine with methane-sludge combustion combustor to organize burning.Namely adopt grate firing to add suspension combustion, combustion intensity is high, and burning completely, fully.
2, methane-sludge combustion combustor adopts air feeding in center vortex burner.Biogas fills into from the biogas pipe in central air hose, is longer biogas/air pre-mixing pipe between the outlet of biogas pipe and central air hose export.This structure is conducive to ensureing that biogas catches fire in time, and shortens the length of flame of biogas, ensures biogas efficiently burning in the confined space.The biogas of premix, after central air hose ejection, directly enters high temperature recirculation zone and mud mixed combustion that First air formed, for mud provides more heat and combustion-supporting gas, to mud catch fire and smooth combustion highly beneficial.
3, because mud catches fire difficulty, combustion instability, therefore adopt pulverized coal carried by hot air, to reduce the required caloric receptivity that catches fire.First air is direct current, and Secondary Air, by producing stronger rotation during swirl vane, namely forms rotating jet after spout injection.Utilize rotating jet, the high temperature gases recirculating district being beneficial to mud and catching fire can be formed, and air-flow is mixed strongly.Capacity of returns, with enlarging angle, to increase the extended corner of jet, is strengthened in other first and second air port.
4, hogging is water-cooled arch, namely on fin panel casing, lays refractory material, and is in tilted layout, low after front height.Burning gases are separated to rise toward both direction, and again collaborates on hogging and produce air whirl.Enable the abundant mix and blend of the gas of two types thus also can realize when hypoxemia burning completely, decrease nitrogen oxide significantly with the discharge capacity of the pernicious gases such as bioxin.Hogging can strengthen the burning in primary zone simultaneously, and the high-temperature flue gas in primary zone introducing face arch is improved ignition condition.
5, arrange adiabatic front and back arch, face arch has certain height and enough swept areas, and the high-temperature flue gas under arch directly to rubbish bed of material radiations heat energy, can burn heat face arch again simultaneously, strengthen face arch to rubbish bed of material thermal radiation capability.Adopt low and long rear arch, except plaing except covering effect to rear portion grate, the anteriorly drainage of rear portion high-temperature flue gas can also be organized, to strengthen the heat radiation of rubbish face arch just having been entered to stove, and the red-hot particle carried secretly in high temperature gas flow is scattered on the rubbish bed of material of grate front end.Rear arch can the burning in overheavy firing district to the covering in primary zone, can ensure burning of burnt zone again simultaneously.
6, at arch place, front and back arranging multiplayer Secondary Air, make full use of the effect of high speed Secondary Air jet leader tape and propelling movement flue gas, strengthen the disturbance of flue gas, cause flue-gas swirl, the stroke of prolong smoke in stove, improve the degree of filling of gas stream in the stove, fuel fully mixed with air, burns completely, burn.
