Rubbish burns 2 light room introduce with brick of accumulation of heat

Rubbish burns use two firebox more for example environmental protection, one firebox burns article, 2 firebox use brick of accumulation of heat, can let combustion and colleague of accumulation of heat undertake, burn at the same time flue gas, at the same time accumulation of heat, assure the temperature that burn, let rubbish burn more complete.


2 light room in the incinerator of rubbish of the 2nd firebox that connecting namely 2 lighting the setting of the room is burning in case generation of the meeting when rubbish is polluted 2 times, what 2 times firebox burns actually is the flue gas after primary combustion room burns, the temperature when burning because of primary combustion room is average very won't tall, sometimes very difficult a poisonous and harmful comb-out in flue gas, add 2 times at the back of primary combustion room so burn. Fluid-bed is a body of heater it seems that, but the bottom when actually fluid-bed is moving is to burn rubbish, upside is to burn of tail gas, just, 2 times firebox is done was in one case.
Incinerator sets two firebox, light namely room and 2 light room, use means of two class combustion, burn room combustion solid, 2 burn room combustion gas: Solid rubbish is entered light room hind to be in book temperature condition to fall to heat up solution through oxygen of dry, be disgusted with, light, controlled virulent gas effectively (2 evil flower) generate; The gas of the hot generation that understand place is entered 2 light the room is sufficient combustion, handled poisonous and harmful gas effectively. The course lights the solid grey broken bits after room processing, classics ground storehouse is collected, reclaim after scrap iron and glass, be used integratedly to make light-duty housing materials. Should burn equipment is rotary kiln + 2 light room + tail gas handles equipment; Use 2 times when accomplish more than heat, pass hot water heat exchanger, can offer hot water to the user is used or be used circularly; Sparge of tail gas classics absorbs dust catcher of type of adsorption of tower, active carbon, efficient bag to purify; Light room furnace temperature to be 850~900 Celsius, 2 light room 1000~1200 Celsius; The time that high temperature flue gas keeps inside furnace truly big with be equal to 2.0S; Combustion efficiency is more than be equal to 99.9% ; Burn purify rate is more than be equal to 99.99% ; Burn residual hot bright is decreased rate be less than 5% ; Height of incinerator exhaust canister is more than be equal to 35 meters.
Rubbish burns 2 light room with characteristic of brick of accumulation of heat 1, the thermal capacity of brick of accumulation of heat depends on generally speaking the material of the material of brick of accumulation of heat reachs density to still have specific heat capacity character. Density is bigger specific heat capacity is larger, its thermal capacity is higher also. So it should have accumulation of heat of pottery and porcelain high density and character of high specific heat capacity. 2, the gas of brick of accumulation of heat is current the area should be quite large, distributing equably, can reduce aeriform resistance so, make the interface of gas and matrix increases, ensure matrix is had conduct an area effectively more greatly. 3, the heat of accumulation of heat of pottery and porcelain delivers a gender is a main index, the brick of accumulation of heat that has admirable hot conductibility can fast deliver quantity of heat to colder waste gas, make waste gas warms up quickly. 4, it is euqally important that the hot absorbency of accumulation of heat of pottery and porcelain delivers a gender with heat, when the hot waste gas after purify passes matrix, the absorption with OK and rapid matrix quantity of heat, the waste gas after be being purified when drops in temperature quickly. 5, brick of accumulation of heat should is should periodic, repetitious is absorbed, release quantity of heat, namely brick of accumulation of heat can relapse warm up to drop in temperature namely, the heatproof shake function of brick of accumulation of heat is very so main.
Burn the flue gas of generation enters the 2 harmful material that ashes did not burn in burning room flue gas to be in 2 light in the room farther destroy by melting or burning. Decompose thoroughly to make did not burn ashes material, achieve discharge a requirement, 2 light room setting burner supports combustion, configured the device that offer wind 2 times distinctive, in order to make sure flue gas is contacted adequately in oxygen of high temperature similarly hereinafter, make sure flue gas is in at the same time 2 light the detention time of the room and undertake adjustment laying wind force according to the 2 volumes containing oxygen that burn room export flue gas. 2 light indoor temperature control to be in 1000~1200 Celsius, ensure retention period is more than 2s, make flue gas is decomposed adequately inside furnace burn, achieve thereby taller decompose rate. In the meantime, the dust of big diameter in flue gas falls 2 light room bottom to finish primary remove dust. Remove dust to the dust of 40um bead diameter efficiency is more than 90% . Lest contain dirt flue gas to enter heat exchanger directly, big diameter dust is outside heat exchanger mural deposit, cause jam. Drop in temperature to make flue gas rapid, avoid thereby 2 evil answer generate once more, in 2 lighted room hind to install water heat exchanger and air heat exchanger. Heat exchange of two class air is entered after high temperature flue gas and water heat exchanger are exchanged, flue gas temperature from 1100 Celsius by will come quickly 200 Celsius, enter sequel to handle installation; After cold water is exchanged via heat, warm up by 40 Celsius to 65 Celsius, use for the user. Air cooling warms up to support combustion into furnace to 200 Celsius by 20 Celsius.
Rubbish burns 2 light room weigh checker brick, matrix again with brick of accumulation of heat of brick of accumulation of heat, have the following advantage: (Of 1) unit volume conduct heat the area is large, for example the area comparing a list of body of beehive of L00n ／ M2 is Φ15mm ball 5.5 times, 7 times of Φ20mm ball. Below same condition, the 4 ～ of 1 ／ that will wait for quality gas heat exchange to be spherule matrix only to the beehive body volume when same temperature 1 ／ 3, the 1 ／ that quality is a ball only 10 the left and right sides, the structure that this means burner of beehive body accumulation of heat is more compact. (2) beehive body wall is thin, only 0.5 ～ Lmm, fully hot deepness is small, accumulation of heat, radiative rate is consequently rapid, temperature efficiency is tall, reversal time is 30 ～ 60s only, this reversal time than spherule matrix 3 ～ LOmin shortens greatly, more benefit Yu Jun changes field of the temperature inside furnace, make sure workpiece heats equably. (Form of passageway of the air current between the grid inside 3) beehive body is regular, aeriform flow is smooth, its obstruction loss is lesser, the ／ of 1 ／ 4—1 that is spherule matrix only 3. Loss of obstruction of spherule matrix air current increases along with velocity of flow and increase, its change rule concerns for power function, ball way is old its obstruction decrescent, but structure of obstruct of accumulation of heat also should increase accordingly. Because beehive body has the gas of higher pressure frequent inverting, rose to blow at the same time brush passageway action, reason produces dirt deposit not easily to jam phenomenon. (4) has liquidity because of spherule, stability of spherule of the upside when regenerator level is placed is poor, incidental knock-on phenomenon, and beehive body is likely without this kind.
Burn about rubbish 2 light room introduce here with brick of accumulation of heat, hope to be helped somewhat to everybody. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
