Abstract
The utility model relates to a coal-fired boiler re-arranged refuse incinerator in a chain type; an original boiler is widened, lengthened and heightened, forming a refuse incinerator with an arch-shaped incinerator top in a front and back drop height type. The utility model is composed of a feed inlet, a high arch type hearth, a lower arch type hearth, a chain grate, an air supply pipe, an air bin, a front and back movable chain wheels, a grate supporting roller, a waste heat boiler, a fume pipeline and a slag storing chamber. After the utility model is adopted by government for central heating, all disused coal-fired boilers of an existing residential area can be improved; the utility model is used for processing domestic refuse and eliminating environmental pollution. The heat quantity recovered by the waste heat boiler can be supplied for cell resident for heating or power generation. The general improvement investment is small.
Description
The utility model relates to a kind of coal-fired boiler reform type consumer waste incineration device.
Reformed since the evolution, city dweller's residential building has had bigger development, for solving heating, burning coal boiler room that many residential buildings are all newly-built, this has brought severe contamination for the air in the sky, city, and scattered boiler room is closed down in government's central heating of making a decision, for example, eight boiler rooms have just newly been closed down in the Beijing Capital Iron and Steel residential block.
The purpose of this utility model is that the boiler plant that close down the residential block is carried out appropriate reconstruction, makes it to become the traveling-grate stoker coal-fired boiler reform type incinerator that can handle life of urban resident rubbish.
The purpose of this utility model is achieved in that to take at the bottom of original boiler foundation widens, extends, increases, and makes traveling-grate stoker extend, widen, reconstruct front and back drop height type arch form furnace roof incinerator with whole body of heater.This stove is made up of charging aperture, high arch form burner hearth, low arch form burner hearth and object-catching chamber.There is heat-resisting plate washer the burner hearth both sides.Burner hearth bottom has traveling-grate stoker.The traveling-grate stoker two ends have increased back stingy movable sprocket again by the front wheel driving sprocket wheel of former boiler, and the fire grate carrying roller is arranged at the traveling-grate stoker bottom.Air feed pipe and wind storehouse are arranged between upper and lower traveling-grate stoker.Waste heat boiler is equipped with at the top behind traveling-grate stoker top, the high arch form burner hearth.Waste heat boiler one side is equipped with flue.Low arch form burner hearth rear end is connected to object-catching chamber, and object-catching chamber does not hold sealing slag door is housed, and object-catching chamber is equipped with the upper end slag door and promotes motor.
Existing equipment utilized problem after the utility model had solved and closed down the boiler room, and original boiler plant traveling-grate stoker still can use, and the reconstruction process does not need to handle new examination and approval procedures, did not newly account for the soil, did not newly construct the factory buildings; Suitably after the reconstruction, can handle the house refuse of housing-group residential block, eliminate city environmental pollution; The heat energy that waste heat boiler reclaims can be the community resident heating, or can be used to generating.The required transformation cycle is short, and expense is low, effect is good, and can solve the part laid-off worker problem of employment, is to achieve many things at one stroke.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a traveling-grate stoker coal-fired boiler reform type incinerator profilograph;
Fig. 2 is that this stove A-A is to drawing in side sectional elevation.
(1) charging aperture, (2) high arch form burner hearth, (3) insulation furnace wall, (4) heat-resisting plate washer, (5) traveling-grate stoker, (6) air feed pipe, (7) wind storehouse, (8) fire grate carrying roller, (9) preceding stingy movable sprocket, the stingy movable sprocket in (10) back, (11) waste heat boiler, (12) flue, (13) low arch form burner hearth, (14) object-catching chamber, (15) sealing slag door, (16) slag door promote motor, (17) drop height type arch form furnace roof among the figure.
Be the details and the working condition of the concrete device that the utility model proposes below.
This device left upper end is charging aperture (1), and the lower end of charging aperture (1) is connected with high arch form burner hearth (2); Hearth wall is the insulation furnace wall (3) that high-temperature refractory is made, and fire-resistant plate washer (4) is equipped with in the burner hearth both sides; Burner hearth bottom is equipped with traveling-grate stoker (5), and the installation site of traveling-grate stoker (5) is that left end (by charging aperture) is high slightly, and right-hand member (by slag notch) is low slightly, forms certain gradient; Airduct (6) He Fengcang (7) is housed between the traveling-grate stoker (5); Fire grate carrying roller (8) is arranged at traveling-grate stoker (5) bottom; Traveling-grate stoker (5) upper end is a preceding stingy movable sprocket (9), and right-hand member is that movable sprocket (10) is scratched in the back; Waste heat boiler (11) is equipped with at traveling-grate stoker (5) top, top, high arch form burner hearth (2) back, and waste heat boiler is equipped with flue (12) first; Low arch form burner hearth (13) is connected with high arch form burner hearth (2); Low arch form burner hearth (13) rear end is connected to object-catching chamber (14), and there is sealing slag door (15) in object-catching chamber (14) not termination, and object-catching chamber (14) upper end is equipped with the slag door and promotes motor (16); Whole chamber structure front portion (left end) is a high arch form burner hearth (2), and rear portion (right-hand member) is low arch form burner hearth (13), forms drop height type arch form furnace roof (17).
The technical process of burning is: at first after a pile spunk is lighted in below, traveling-grate stoker (5) the left end top of charging aperture (1), crude waste is thrown on the firewood of burning from charging aperture (1), air feed pipe (6) He Fengcang (7) beginning air feed is combustion-supporting.Traveling-grate stoker (5) by fire grate carrying roller (8) and forward and backward stingy movable sprocket (9), (10) drive rubbish in high arch form burner hearth gently, move from left to right incessantly, and constantly burn.The heat that burning produces makes waste heat boiler (11) produce steam heating or generating.Rubbish burns away, and shift-in extremely hangs down arch form burner hearth (13) forward.The rubbish that burnouts then becomes slag and enters object-catching chamber (14).
Under the drive that forward and backward stingy movable sprocket (9), (10) are arranged, and the gradient influence that traveling-grate stoker (5) itself has a down dip to the right down, and the rubbish on the traveling-grate stoker (5) moves incessantly from left to right, and phenomenon can not get stuck.Flame in the burner hearth is contrary fire grate rotation direction burning, make the flame new rubbish that continuously ignites, rubbish is entered from charging aperture, promptly be subjected to giving heat, go up constantly burning, constantly reach at traveling-grate stoker (5) then, after burnouting into slag, enter object-catching chamber, produce the rubbish continuous burning motion process that goes round and begins again, form the suitability for industrialized production incinerator.The burner hearth overall structure is that drop height type arch furnace roof can produce high radiant heat, thermal efficiency height, and burning is fully.
An improved incinerator can day be burnt away the refuse 200 tons, can focus on the house refuse of 200,000 populations, and the heat energy that reclaims of waste heat boiler can day producing steam 140 tons simultaneously, can also can be used to generating for 700,000 square metres of community resident heat supplies.Burn away the refuse the flue gas that produces after circulating water treatment, can reach the effluent standard physical and chemical index that meets national requirements for environmental protection.Clinker can be used as construction material.
