Abstract
The utility model discloses a boiler room is reformed transform secondary flue gas and is utilized system, include through consecutive boiler, denitration room, clean room, desulfurization chamber, chimney and the secondary flue of flue, be provided with the primary air fan between desulfurization chamber and the chimney in the flue that links to each other, the flue that links to each other between the flue that links to each other between the flue, denitration room and the clean room that link to each other between boiler and the denitration room and clean room and the desulfurization chamber is all continuous with the chimney once more through the secondary flue. Wherein, boiler flue gas from the boiler back of coming out, partly flue gas passes through the denitration room in proper order, the chimney last is sent into by the fan to clean room and desulfurization chamber, another part through genuine with remove dust through SOx/NOx control after the flue gas mix the back discharge in the chimney. The pipeline that denitration room, dust removal and desulfurization chamber came out divide into two respectively, wherein one insert genuinely and send into the chimney by the fan in discharge. The utility model discloses can be applied to widely among the recovery process of boiler room secondary flue gas.
Description
Technical field:
The utility model belongs to transformation field, boiler room, is specifically related to a kind of boiler room transformation secondary flue gas and utilizes system.
Background technology:
At present, the temperature of boiler room flue gas after desulfur denitrate dust collecting is very low, and low-temperature flue gas enters in chimney can cause great corrosion to chimney, and just very high from boiler flue-gas temperature out, high-temperature flue gas is carried out secondary recovery, then can reduce the corrosion of chimney.
Utility model content:
The purpose of this utility model is the temperature effectively utilizing boiler smoke self, provide a kind of boiler room transformation secondary flue gas and utilize system, boiler smoke is divided into two parts by it, a part mixes in chimney with another part boiler smoke successively after desulfur denitrate dust collecting, realize the recovery of fume afterheat, higher exhaust gas temperature can be obtained, effectively utilize the heat of boiler smoke, reduce the corrosion of chimney, improve the utilization of boiler smoke.
For reaching above object, the utility model adopts following technical scheme to be achieved:
A kind of boiler room transformation secondary flue gas utilizes system, comprises the boiler, denitration chamber, dirt pocket, desulfurization chamber, chimney and the secondary flue that are connected successively by flue, is provided with primary air fan in the flue be connected between desulfurization chamber and chimney;
The flue be connected between boiler and denitration chamber, the flue be connected between denitration chamber and dirt pocket and the flue be connected between dirt pocket and desulfurization chamber are all connected with chimney again by secondary flue.
The utility model further improves and is, the flue be connected between boiler and denitration chamber is connected with secondary flue by the first valve.
The utility model further improves and is, the flue be connected between denitration chamber and dirt pocket is connected with secondary flue by the second valve.
The utility model further improves and is, the flue be connected between dirt pocket and desulfurization chamber is connected with secondary flue by the 3rd valve.
Compared with prior art, the beneficial effects of the utility model are:
1, utilize the temperature of boiler smoke self to heat the flue gas after desulfur denitrate dust collecting, while fully efficiently utilizing boiler smoke, alleviate the smoke evacuation burden of chimney, also protective effect is served to chimney;
2, effectively utilize the heat energy of boiler smoke, reduce energy dissipation, realize the object of energy-saving and emission-reduction;
Further, arm after boiler, denitration chamber, dirt pocket and desulfurization chamber arranges valve respectively, the sulfur-bearing of effective control secondary flue gas is containing sales volume, part boiler smoke passes in secondary flue, effectively alleviates the burden of desulphurization denitration room and dirt pocket and reduces the operating cost of desulphurization and denitration or dedusting.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram that a kind of boiler room transformation of the utility model secondary flue gas utilizes system;
In figure: 1, boiler; 2, denitration chamber; 3, dirt pocket; 4, desulfurization chamber; 5, chimney; 6, primary air fan; 7, overfire air fan; 8, the first valve; 9, the second valve; 10, the 3rd valve; 11, secondary air channel.
Detailed description of the invention:
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of boiler room transformation of the utility model secondary flue gas utilizes system, comprise the boiler 1, denitration chamber 2, dirt pocket 3, desulfurization chamber 4, chimney 5 and the secondary flue 11 that are connected successively by flue, in the flue be connected between desulfurization chamber 4 and chimney 5, be provided with primary air fan 6; The flue be connected between boiler 1 and denitration chamber 2, the flue be connected between denitration chamber 2 and dirt pocket 3 and the flue be connected between dirt pocket 3 and desulfurization chamber 4 are all connected with chimney 5 again by secondary flue 11.
Further, the flue be connected between boiler 1 and denitration chamber 2 is connected with secondary flue 11 by the first valve 8; The flue be connected between denitration chamber 2 and dirt pocket 3 is connected with secondary flue 11 by the second valve 9; The flue be connected between dirt pocket 3 and desulfurization chamber 4 is connected with secondary flue 11 by the 3rd valve 10.
In order to understand further the utility model, now its course of work is described further:
Boiler smoke is out divided into two afterwards from the smoke exhaust pipe of boiler 1, and one connects denitration chamber 2, and another receives in secondary flue 11, arm is provided with the first valve 8, regulates the flue gas sent in secondary flue 11 with the first valve 8; Be further divided into two from denitration chamber 2 flue out, receive dirt pocket 3 for wherein one and carry out dedusting, another receives in secondary flue 11, regulates the exhaust gas volumn entering secondary flue 11 with the second valve 9; Equally, be also divided into two from dirt pocket 3 flue out, wherein an access desulfurization chamber 4, another to be received in secondary flue 11 and enters the exhaust gas volumn of secondary flue 11 with the 3rd valve 10 control.If boiler smoke is very high containing nitre amount, then closes the first valve 8, regulate the second valve 9, control the exhaust gas volumn in access secondary flue 11; If the dustiness of boiler smoke is very high, then close the first valve 8 and the second valve 9, regulate the 3rd valve 10.Open and close according to the dustiness of boiler smoke and regulate the first valve 8, second valve 9, the 3rd valve 10.
