C. economizer tail gas is subjected to cooling neutralization；
D. it is discharged after the flue gas after cooling neutralize being carried out cooling neutralization again.
As an improvement tail gas is being passed through economizer after first carrying out dust removal process in the step B.
As an improvement two accesses of kiln outlet setting, one leads to chimney, and another leads in the step A
Waste heat steam boiler；Access towards chimney is normally closed and the access towards waste heat boiler is normally opened.
As a preference, cooling is exchanged heat while neutralizing tail gas using water cooling heat exchanger in the step C.
As an improvement the neutralizer for being neutralized with tail gas is recycled by air-cooled cooling tower in the step C
It is cooling.
As a preference, carrying out cooling neutralization to flue gas using chilling scrubbing tower and scrubbing tower in the step D.
As an improvement two accesses are arranged in the flue gas in the step C after cooling neutralization, one leads in line cigarette
Chimney, another leads to chilling cooling tower；Access towards direct exhaust chimney is normally closed and the access towards chilling scrubbing tower is normally opened.
As an improvement the neutralizer in the step C and step D for neutralizing flue gas is sodium hydroxide solution.
As an improvement the flue gas for exporting out from kiln in step A is passed through waste heat steam boiler after being slowed down.
The invention has the beneficial effects that: the solvent recovery technology from vent gas with above-mentioned steps carries out waste heat benefit in hot stage
With utilization rate of waste heat is high.And the equipment by being located at system rear after heat exchange is no longer influenced by the erosion of high-temperature flue gas, improves
The service life of equipment.After carrying out tail gas recycle, whole system is stable, furnace pressure energy stability contorting, and production is stablized.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, With reference to embodiment
The present invention is described in further detail.
As shown in Figure 1, the present invention the following steps are included:
A. the flue gas that kiln exports is passed through waste heat steam boiler burner hearth and carries out heat exchange；First choice, kiln outlet utilize three
Two accesses are arranged in smoke uptake I, and one leads to chimney, and another leads to waste heat steam boiler；Access towards chimney it is normally closed and
Access towards waste heat boiler is normally opened.When the maintenance of waste heat steam boiler one end, chimney direct emission flue gas is utilized.From kiln
The flue gas utilization damping vane that outlet of still comes out is passed through waste heat steam boiler after being slowed down.Waste heat steam boiler is a kind of energy
Conversion equipment, the combusting coal fines in its burner hearth, for the water in water-cooling wall to be converted to steam.Flue gas in tank furnace is directly logical
Enter in burner hearth, to carry out heat exchange with water, flue-gas temperature can not only be effectively reduced, and can effectively absorb waste heat.
B. the tail gas of waste heat steam boiler is passed through economizer and carries out heat exchange；Tail gas is being passed through after first carrying out dust removal process
Economizer.And economizer is mounted to boiler back end ductwork lower part for recycling a kind of device of discharged fume waste heat, by boiler
Water supply is heated into the heating surface of the saturated water under drum pressure, since it absorbs the heat of high-temperature flue gas, reduces the row of flue gas
Smoke temperature degree, saves the energy, improves efficiency, so referred to as economizer.It is connected between waste heat steam boiler and economizer
Dust pelletizing system, and air inducing is carried out using air-introduced machine.A large amount of particulate contaminant is had in waste heat steam boiler after coal dust firing to converge
It closes in flue gas, so just can enter next process after needing to be dusted it processing.The waste heat boiler is provided with ash
Slag receives and keeps case, and the deduster is provided with dust box.To collect particle waste, and the same slag treatment factory that is transported to carries out
Processing.
C. economizer tail gas is subjected to cooling neutralization；It is exchanged heat while cooling neutralization tail gas using water cooling heat exchanger.
Neutralizer for being neutralized with tail gas passes through air-cooled cooling tower circulating cooling.Cooling neutralize in this step is washed using spray
Tower progress is washed, due to entering the flue-gas temperature of spray washing cooling tower or relatively high, after neutralizer and flue gas carry out heat exchange
Temperature increases quickly, therefore is cooled down by air-cooled cooling tower to neutralizer, then return again to spray washing cooling tower into
Row spray, improves rate of heat exchange.Water cooling heat exchanger carries out heat exchange again by water and flue gas, thus to absorb waste heat
Device.Neutralizer is sodium hydroxide solution.
D. it is discharged after the flue gas after cooling neutralize being carried out cooling neutralization again.Using chilling scrubbing tower and scrubbing tower to flue gas
Carry out cooling neutralization.Two accesses are arranged in three smoke uptake TT of flue gas utilization in step C after cooling neutralization, and one leads in line cigarette
Chimney, another leads to chilling cooling tower；Access towards direct exhaust chimney is normally closed and the access towards chilling scrubbing tower is normally opened.When useless
Gas processing system overhauls or when breaking down, in order to avoid bigger loss, can use connect with three smoke uptake II it is straight
Smoke evacuation chimney is discharged.Chilling scrubbing tower, according to being connected, is connected with exhaust fan on the scrubbing tower with scrubbing tower.Spray washing is cooling
Tower, chilling scrubbing tower and scrubbing tower spray flue gas using lye.Lye is emitted into sewage treatment plant and is handled.It is anxious
Cold scrubbing tower is similar with the structural principle of scrubbing tower, is the equipment sprayed for carrying out cooling neutralization to flue gas.Chilling washing
The effect of tower focuses on cooling, and the effect of scrubbing tower focuses on neutralization.
In the present invention, the high-temperature flue gas in tank furnace is by the water in waste heat steam boiler, economizer, spray washing cooling tower
Cold heat exchanger absorbs waste heat step by step and utilizes, and eventually by being discharged after neutralization, not only increases heat utilization efficiency, reduces
Cost, and avoid high-temperature flue gas direct emission to environment and to the corrosion of follow-up equipment.
The above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
Limitation of the invention, protection scope of the present invention should be defined by the scope defined by the claims..For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, several improvements and modifications can also be made, these change
It also should be regarded as protection scope of the present invention into retouching.
