2Deng.Because they have the performance that compares favourably with carbon black and are the characteristic of white in appearance, therefore be referred to as white carbon.
In the production process of white carbon, the white carbon slurry adopts heated-air drying usually, and the hot-blast stove operation need to gather a large amount of clean dry airs as heat carrier.
Approximately 80 ~ 90 ℃ of the exhaust temperatures that dry bag filter air-introduced machine is discharged contain a large amount of water vapours.The common way of white carbon enterprise is that tail gas is introduced spray column, and water spray recycle-water steam reclaims the hot water that obtains and is used for white carbon preceding working procedure washing leaching cake.Remaining hot-air (carrying a small amount of water droplet secretly) is then directly emptying after having reclaimed water vapour.
Because hot-air contains a large amount of heat energy, directly emptyingly will cause a large amount of energy wastes.
The utility model content
The purpose of this utility model is to provide a kind of white carbon dried tail gas cyclic utilization system, takes full advantage of tail gas to reach energy-saving and cost-reducing purpose.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of white carbon dried tail gas cyclic utilization system comprises
Hot-blast stove, described hot-blast stove is connected with drying tower, for heat air delivery in drying tower;
Here contact with hot-air behind the drying tower, white carbon slurry atomizing and be dried; Produce simultaneously a large amount of steam-laden hot-airs.
Bag hose, described bag hose is connected with drying tower, is used for capturing the white carbon dry powder that obtains after the drying tower drying; And isolate steam-laden hot-air.
The water spray column, described water spray column is connected with bag hose, is used for the water vapour that spray reclaims tail gas;
Gas-liquid separator, described gas-liquid separator is connected with the water spray column, and the hot-air that contains drop here drop is separated, and obtains dry hot-air;
Purify bellows, described purification bellows are connected with hot-blast stove with gas-liquid separator respectively, and dry hot-air is by introducing hot-blast stove here.
Wherein, described purification bellows are the seal case that is provided with air inlet, gas outlet and filter screen, and described air inlet is connected with gas-liquid separator, and described gas outlet is connected with hot-blast stove, and described filter screen is arranged in the casing outside and enters hot-blast stove with the dust of blocks air.
The white carbon dried tail gas cyclic utilization system that the utility model adopts, the hot-air that tail gas is obtained behind water spray column spray recycle-water steam further enters the purification bellows, returns the hot-blast stove recycling after gas-liquid separation, realized the recycling of tail gas, make the exhaust emissions amount reduce to zero, the environment protecting highly significant; And still contain a large amount of heat energy owing to having reclaimed in the hot-air that obtains after the water vapour, it is returned hot-blast stove re-use, can greatly reduce the energy that the hot-blast stove heated air consumes, reach energy-saving and cost-reducing purpose.The experiment proved that, the clean air temperature of existing supply hot-blast stove is generally at 25～30 ℃, and the hot air temperature that the utility model is recycled can be up to 80 ℃, to be the utility model Purge gas of supplying with hot-blast stove than the clean air of existing supply hot-blast stove can lack heats up 50 ~ 55 ℃, and hot-blast stove can save energy more than 10%.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and cooperate accompanying drawing to give in detail explanation.
See also shown in Figure 1ly, the white carbon dried tail gas cyclic utilization system of the present embodiment comprises
Hot-blast stove 1, described hot-blast stove 1 is connected with drying tower 2, is used for to drying tower 2 interior heat air deliveries 10;
Here contact with hot-air behind the drying tower 2, white carbon slurry atomizing and be dried; Produce simultaneously a large amount of steam-laden hot-airs.
Gas-liquid separator 4, described gas-liquid separator 4 is connected with water spray column 3, and gas and liquid for separating of in the moisture hot-air 30 that obtains after reclaiming obtain dry gas 40 and hot water, hot water is discharged by the discharge outlet of gas-liquid separator 4, and dry gas 40 then enters and purifies bellows 5;
Purify bellows 5, described purification bellows 5 are connected with hot-blast stove 1 with gas-liquid separator 4 respectively, and the Purge gas 50 that is used for obtaining after the dry gas 40 of purification through obtaining after the gas-liquid separation also will purify is introduced hot-blast stoves 1.
Circulation of tail gas process of the present utility model is roughly as follows:
1, the high-temperature hot-air 10(after hot-blast stove 1 heating is approximately 500 ℃) enter drying tower 2 interior dialogue carbon black slurries and carry out drying, form approximately 80 ~ 90 ℃ the tail gas 20 that is entrained with a large amount of water vapours;
2, tail gas 20 is incorporated in the water spray column 3, the water spray reclaims the water vapour in the tail gas 20, the hot water that recovery obtains is used for the washing leaching cake operation of white carbon, tail gas 20 behind the spray forms moisture hot-air 30 because being entrained with a large amount of water droplets simultaneously, this moment, moisture hot-air 30 can not directly be used as the heat carrier of hot-blast stove 1, and must remove the water droplet of wherein carrying secretly;
