Control changes appropriate adjustment blower volume of air supply according to furnace pressure to guarantee that furnace pressure balances.Automatic discharge valve has highly dense
Feng Xing guarantees that flue gas does not leak outside in tapping process.Because deslagging scraper plate is structure as a whole with distributing wind disc, control is returned with distributing wind disc
Rotary driving device is mutually chain, and lime-ash centralized collection after automatic discharge valve is handled.Smoke reflux device is by air-introduced machine, flow
The composition such as meter, pipeline, blower and feeder, upper of furnace body pressure gauge chain control each other, according to inlet amount, furnace interior pressure
The practical control smoke backflow amount of power.Smoke reflux device air outlet deeply to gasification furnace oxide layer and is higher by distributing wind disc 400mm,
Purpose is to be able to carry out the tar material contained in flue gas after second pyrolysis gasifies.Have reached combustible gas preliminary purification purpose.
The main problem solved using above-mentioned technical solution is as follows:
1. solving the problems, such as that gasification furnace internal temperature is insufficient
Most of tradition gasification furnace bodies are mostly watertight seal sleeve structure, and structure, which absorbs, consumes a large amount of in-furnace temperatures, make gas
Changing furnace peripheral temperature reduces and influences gasification efficiency, and furnace is interior after installation refractory heat-insulating wall promotes and peripheral temperature increases, and uniformly
Gasification efficiency is considerably increased, flammable gas calorific value after gasification is promoted.
2. combustible gas tar content is high after solving the problems, such as gasification
Gas reflux is able to carry out tar to gasification furnace oxide layer after the design of combustible gas oil gas reflux unit makes gasification
Second pyrolysis.Complete the preliminary purification to combustible gas.
3. solving the problems, such as that the bed of material is unstable inside gasification furnace
The design of rotating distributor install additional torque sensor and with feeder chain control each other, inside accurate gasification furnace
Bed depth increases gasification result.
4. solving the problems, such as traditional gasification furnace detachable maintaining and pulp water mixing
The design of furnace bottom lower flange support keeps the gasification any component of furnace apparatus detachable at any time and is overhauled, and takes
Disappear the sealing structure for water of original gasification furnace, separates pulp water, facilitates deslagging.
5. solving the problems, such as that traditional air feed system air quantity is uncontrollable and timing moisturizing
Fresh air system be divided into air feed and oil gas reflux air flue and install additional respectively flowmeter and anemobiagraph can more be precisely controlled to
Air quantity and oil gas regurgitant volume, while cancelling sealing structure for water and simplifying installation manufacture difficulty, also eliminating water seal needs the work of timing moisturizing
Make.
6. solving the problems, such as deslagging
There is residual cake valve stringent leakproofness to guarantee that furnace interior flue gas does not leak outside, and open simultaneously with distributing wind disc chain control
It closes.
