Abstract
The invention provides a boiler flue gas treatment process. The boiler flue gas treatment process includes the following steps that 1, heat of flue gas exhausted by a boiler is recycled through waste heat recycling equipment; 2, the temperature of the flue gas obtained after waste heat recycling is reduced, the flue gas enters a multi-tube dust remover, and the multi-tube dust remover carries out preliminary dust removal on the flue gas; 3, the flue gas obtained after preliminary dust removal of the multi-tube dust remover enters a bag-type dust remover for secondary dust removal; 4, the flue gas obtained after secondary dust removal is introduced into a desulfuration dust removal tower through an induced draft fan; 5, alkali liquor in an alkali liquor adjusting pond enters the desulfuration dust removal tower through a spraying pump, the alkali liquor and the flue gas are subjected to a neutralization reaction, sulfur-containing gas in the flue gas is neutralized, and dust in the sulfur-containing gas settles; 6, the gas reaching the standard after being treated through the desulfuration dust removal tower is exhausted into the atmosphere. After dust removal of the multi-tube dust remover and the bag type dust remover, dust in the flue gas can be effectively removed; by means of the neutralization reaction carried out in the desulfuration dust removal tower, sulfur-containing pollutants in the flue gas can be effectively removed; the waste heat recycling equipment can recycle the waste heat in the flue gas, and the utilization rate of heat energy is increased.
Description
Technical field
The present invention relates to paper industry technical field of waste gas treatment, more particularly to a kind of boiler smoke handling process.
Background technology
Paper industry be national economy production in a very important department, it not only produce people's culture life and
Indispensable paper in daily life, and produce the industrial paper needed for substantial amounts of each department of national economy production.Making
During paper, there are many links to need to be heated with boiler, these boilers are inevitably resulted from big during combustion heating
Amount flue gas, these flue gases itself also contain higher heat, if be directly discharged in air, can cause the loss in vain of heat energy,
Waste the energy;And in the flue gas of the boiler emission of paper industry, containing substantial amounts of sulfurous pollutants, these pollutant emissions are arrived
In air, severe contamination can be caused to air, cause the heavy damage of environment.These just because of paper industry boiler smoke
Feature so that boiler smoke is treated as the basic measures must being fulfilled for.
The content of the invention
Present invention address that process demand of the paper industry to boiler smoke, and science and engineering at a kind of boiler smoke is provided
Skill.
The present invention for achieving the above object, is employed the following technical solutions:A kind of boiler smoke handling process, including following step
Suddenly:
1. the flue gas Jing waste heat recovery apparatus of boiler emission reclaim heat;
2. the flue-gas temperature Jing after waste heat recovery is reduced, and into multi-tube dust cleaner, multi-tube dust cleaner is carried out tentatively to flue gas
Dedusting;
3. the flue gas Jing after multi-tube dust cleaner rough dusting enters sack cleaner, carries out final dusting;
4. the flue gas after final dusting introduces desulfurized dust collection column by air-introduced machine;
5. the alkali lye Jing spray pumps in alkali lye regulating reservoir enter desulfurized dust collection column, and are neutralized instead with flue gas therein
Should, the sulfurous gas in flue gas is neutralized, and make dust settling therein;
6. the gas Jing after desulfurized dust collection column process is up to standard enters air.
The invention has the beneficial effects as follows:It is of the present invention Jing after multi-tube dust cleaner and sack cleaner dedusting, can effectively remove
Dust in flue gas;The neutralization reaction carried out in desulfurized dust collection column can effectively remove the sulfurous pollutants in flue gas;Waste heat is returned
Receiving unit can be in recovered flue gas waste heat, improve the utilization rate of heat energy, reduce the pollution to environment.
Description of the drawings
Fig. 1 is the process flow diagram of the present invention;
It is described in detail referring to the drawings below with reference to embodiments of the invention.
Specific embodiment
With reference to embodiment, the invention will be further described:
As shown in figure 1, a kind of boiler smoke handling process, comprises the following steps:
1. the flue gas Jing waste heat recovery apparatus of boiler emission reclaim heat;
2. the flue-gas temperature Jing after waste heat recovery is reduced, and into multi-tube dust cleaner, multi-tube dust cleaner is carried out tentatively to flue gas
Dedusting;
3. the flue gas Jing after multi-tube dust cleaner rough dusting enters sack cleaner, carries out final dusting;
4. the flue gas after final dusting introduces desulfurized dust collection column by air-introduced machine;
5. the alkali lye Jing spray pumps in alkali lye regulating reservoir enter desulfurized dust collection column, and are neutralized instead with flue gas therein
Should, the sulfurous gas in flue gas is neutralized, and make dust settling therein;
6. the gas Jing after desulfurized dust collection column process is up to standard enters air.
The present invention is exemplarily described above, it is clear that the present invention is implemented and is not subject to the restrictions described above,
As long as employing method of the present invention design and the various improvement that carry out of technical scheme, or not improved directly apply to other fields
Close, within protection scope of the present invention.
