Description
Technical field
The utility model relates to a kind of air-introduced machine heater, especially relates to a kind of corrosion-resistant air-introduced machine heater.
Background technology
In boiler operatiopn, the high-temperature flue gas that boiler is discharged can be treated to clean high-temperature gas along with flue enters device for abatement of smoke and dust, then enter into air-introduced machine by flue, but due to the steam not eliminating in air-introduced machine meeting inspiration device for abatement of smoke and dust, steam is sticked on the impeller of air-introduced machine, thereby caused the easy dust stratification of draught fan impeller and be easily corroded, shorten service life, reduce running time, and then cause air-introduced machine running shake, affect safe operation of the boiler.
Utility model content
The purpose of this utility model be exactly provide a kind of in order to overcome the defect that above-mentioned prior art exists and extend air-introduced machine service life, safe and reliable corrosion-resistant air-introduced machine heater.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of corrosion-resistant air-introduced machine heater, this device is connected with air-introduced machine, it is characterized in that, described heater comprises the auxiliary cylinder of the economizer, the first flue, device for abatement of smoke and dust, the second flue and the air-introduced machine that connect successively, the auxiliary cylinder of described air-introduced machine is connected with air-introduced machine, described heater also comprises warm-air pipe, and this warm-air pipe one end is communicated with the first flue, and the other end is communicated with the second flue.
Described warm-air pipe is provided with warm-air pipe air door adjusting valve.
The second described flue is provided with two input ports and a delivery outlet, and two input ports are connected with warm-air pipe, device for abatement of smoke and dust delivery outlet respectively, and delivery outlet is connected with the auxiliary cylinder of air-introduced machine.
Compared with prior art, the utlity model has following advantage:
This device has utilized the fume afterheat that originally will discharge, so can not increase boiler heat loss, and because rapid evaporation the steam in air inducing flue, so alleviated the corrosion of flue and impeller, extend the service life of equipment, reduce the dust stratification on impeller, made the operation of equipment energy safety and steady.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Wherein, 1, economizer, 2, the first flue, 3, warm-air pipe, 4, warm-air pipe air door adjusting valve, 5, the second flue, 6, device for abatement of smoke and dust, 7, the auxiliary cylinder of air-introduced machine, 8, air-introduced machine.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment:
As shown in Figure 1, a kind of corrosion-resistant air-introduced machine heater, comprise the auxiliary cylinder 7 of the economizer 1, the first flue 2, device for abatement of smoke and dust 6, the second flue 5, the air-introduced machine that connect successively and air-introduced machine 8, this fume extractor also comprises warm-air pipe 3 and is arranged on the warm-air pipe air door adjusting valve 4 on warm-air pipe 3, described warm-air pipe 3 one end are communicated with the first flue 2, and the other end is communicated with the second flue 5.
On flue after boiler economizer 1, connect a warm-air pipe 3, walk around device for abatement of smoke and dust 6 and directly receive on the second flue 5.Utilize boiler tail flue gas waste heat, directly wash away air-introduced machine 8 impellers, make the steam rapid evaporation of air-introduced machine 8 inspirations, reduce impeller dust stratification and corrosion, the fume afterheat that this device mainly utilizes boiler tail originally will discharge, walk around device for abatement of smoke and dust 6 by short circuit, directly wash away air-introduced machine 8 flues and impeller, make the steam rapid evaporation in flue.
