Description

A kind of waste heat recovery regenerative furnace
Technical field
The utility model relates to a kind of waste heat recovery regenerative furnace, specifically relates to a kind of waste heat recovery regenerative furnace through carrier regenerator and gas direct heat transfer.
Background technology
At present; Discharged a large amount of waste gas when the workerization industry is produced, waste gas produces huge harm to human body, has polluted atmosphere; Therefore just allow discharging after need exhaust-gas treatment being become innocuous gas; Considerable waste gas is the organic compound of gaseous state, adopt burning process be the most general, effect is better, the waste gas treatment process that cost is minimum.Burning process can produce great amount of heat when handling waste gas, burned waste gas equipment all can be provided with the device of some heat energy recycle.Common burned waste gas equipment heat energy recycle device is that the high-temperature gas after burning is passed through a hot water storgae, and utilization adds hot water and receives heat energy back and forth, and the maximum shortcoming of this recovery method is that the heat energy recycle rate is not high.The waste gas of part burned waste gas treating apparatus directly gets into Burning Room without preheating; The waste gas that big amount temperature is lower gets into Burning Room and can cause the Burning Room temperature low excessively; Burned waste gas is handled insufficient, and most of burned waste gas treating apparatus adds preheating device in addition, and energy consumption is high; Investment is big, complex structure.
The utility model content
The utility model purpose: the purpose of the utility model is to prior art not enough, and a kind of waste heat recovery regenerative furnace is provided.
Technical scheme: the described waste heat recovery regenerative furnace of the utility model comprises: spark arrester, first-class heat exchanger, waste gas distributing chamber, a regenerator, No. two regenerator, No. three regenerator, combustion chamber, spray combustion mixing chamber, smoke distribution chamber, secondary heat exchanger, air-introduced machine and chimneys; In order to prevent back draft, spark arrester was set before the first-class heat exchanger import, a said regenerator, No. two regenerator and No. three regenerator are successively set on the middle part of said combustion chamber; Said waste gas distributing chamber is located at said regenerator below and communicates, and said smoke distribution chamber is arranged at the below of said No. three regenerator and communicates; Said spray combustion mixing chamber is arranged at said top of combustion chamber; Said first-class heat exchanger links to each other with waste gas distributing chamber, and said smoke distribution chamber links to each other with said secondary heat exchanger, air-introduced machine and chimney successively.
In order to increase the accumulation of heat effect, in a regenerator, No. two regenerator and No. three regenerator thermal storage ceramic is set all, thermal storage ceramic and gas direct heat transfer improve firing rate;
The waste gas of collecting at first gets into first-class heat exchanger through spark arrester and carries out heat exchange; Get into a regenerator preheating through waste gas distributing chamber then; The flue gas that produces gets into No. two regenerator; Carry out heat exchange with the thermal storage ceramic in No. two regenerator, No. three regenerator of a small amount of flue gas entering of coming out through the extraction heat exchange play the regenerator effect that purifies, and flue gas progressively burns in three regenerator of combustion chamber and emits heat energy simultaneously; Flue gas after the burning heat release gets into the further heat exchange of secondary heat exchanger through the smoke distribution chamber, and last flue gas causes smoke stack emission to atmosphere by air-introduced machine.
In order further to utilize the waste heat in the waste gas, can heat-energy recovering apparatus rationally be set according to the waste gas situation, connect heat-conducting oil furnace or waste heat boiler at high temperature combustors, low-temperature flue gas is used for heat exhaust gases.
Beneficial effect: 1, the utility model device adopts low-temperature heat exchange, and heat exchange efficiency is high, reclaims the sensible heat in the combustion product to greatest extent, reaches about 95%; Exhaust gas temperature is low, and energy-saving effect is remarkable, has reduced the discharging of greenhouse gases.2, flue gas begins burning gradually in regenerator, and flame does not produce in the combustion chamber, does not therefore have the high temperature sharp side, and combustion noise is low; 3, adopt grading combustion technology, the combustion chamber in temperature rise even, one side has improved purification efficiency; Prolonged the combustion chamber life-span on the other hand; And do not have the localized hyperthermia hyperoxia district that occurs in the traditional combustion process, suppressed the generation of thermal NO, environment protecting is good.4, cost of investment is low, but the processing waste gas of low concentration high flow capacity, can be safely, stable, operation continuously, as far as possible more reclaim heat energy, reduce operating cost.
