Abstract
The utility model discloses a kind of lag cooler dust pelletizing systems, it includes deduster, the import of the deduster and the slag notch of lag cooler receive energy pipeline connection by first, and the outlet of deduster is received energy pipeline by second with the wind inlet channel of boiler primary air fan arrival end and is connected to.Lag cooler dust pelletizing system of the utility model is solving the problems, such as fugitive dust of the lag cooler in tapping process using deduster, improve site environment, the recycling of afterheat of slags is realized simultaneously, improves the temperature of boiler combustion wind, and then improves boiler combustion efficiency and economy.
Description
Technical field
The utility model relates to boiler plant field more particularly to a kind of lag cooler dust pelletizing systems.
Background technique
Since the slag temperature of boiler furnace lower discharge is usually at 800 DEG C or more, there is a large amount of physical sensible heat, if place
It is improper to manage, not only waste of energy, and remaining sulphur and nitrogen are thrown away in lime-ash can discharge sulfur dioxide and nitrogen oxides outside furnace, deteriorates
Live service condition causes environmental pollution, therefore, is provided with lag cooler at the slag-drip opening of boiler plant.
Clinker is expelled in load wagon by lag cooler discharge port after lag cooler is cooling and is transported.Due to discharge port and load wagon
Between there are differences in height, therefore fugitive dust easily occurs when discharge, pollutes site environment and on the other hand burn in furnace by fire coal
The boiler's primary air temperature that required oxygen provides air in the process is generally 25~30 DEG C, although the temperature is for fire coal combustion
Burn, but efficiency of combustion is still to be improved, and generally still has nearly 100 DEG C of high temperature after cooling of furnace slag, then how solution fugitive dust
The problem of while rationally utilize waste heat, be worth inquire into the problem of.
Summary of the invention
The purpose of this utility model is to provide a kind of lag cooler dust pelletizing systems.
The technical solution for realizing the utility model aim is a kind of lag cooler dust pelletizing system comprising deduster, it is described to remove
The import of dirt device and the slag notch of lag cooler are received by first can pipeline connection, the outlet of deduster and boiler primary air fan entrance
The wind inlet channel at end is received by second can pipeline connection.
Further, the first receipts energy pipeline and the second receipts energy pipeline external are enclosed with insulating layer, to prevent heat
It is lost.
Further, the deduster is bag filter.
Lag cooler dust pelletizing system of the utility model is solving lag cooler raising in tapping process using deduster
Dirt problem improves site environment, while realizing the recycling of afterheat of slags, improves the temperature of boiler combustion wind, Jin Erti
High boiler combustion efficiency and economy.
Detailed description of the invention
Fig. 1 is lag cooler dust pelletizing system structural schematic diagram described in the utility model embodiment.
Specific embodiment
The utility model preferred embodiment is described further below in conjunction with attached drawing.
As shown in Figure 1, a kind of lag cooler dust pelletizing system comprising deduster 1, the import 11 of the deduster 1 and cold slag
The slag notch 21 of machine 2 is received by first can 3 connection of pipeline, the outlet 12 of deduster and the air inlet of 4 arrival end of boiler primary air fan
Air duct 41 passes through second and receives the energy connection of pipeline 5, and the first receipts energy pipeline 3 and second receive and be enclosed with heat preservation outside energy pipeline 5
Layer.
When work, clinker is discharged into lag cooler 2 by boiler 10, and the negative pressure that boiler First air 4 generates in operation is by lag cooler 2
Deslagging generate dust and heat collection to deduster 1 in, then dust is filtered by deduster 1, make dust content≤
10mg/m3, the wind inlet channel 41 that the heat of collection then receives the energy introducing boiler primary air fan 4 of pipeline 5 by second, boiler primary air fan
Wind inlet channel 41 temperature through second receive can pipeline 5 collect exhaust-heat heating after be sent into boiler 10.Heated First air can
Be warming up to 70~80 DEG C by 25~30 DEG C, the promotion of the temperature of boiler combustion wind further improve boiler combustion efficiency and
Economy.
Insulating layer described in the utility model can be aluminosilicate fiber cotton layer or other conventional insulation material layers.The dedusting
Device can be bag filter, electric precipitator, the cleaner of the field of environment protection equipment routine such as electric bag mixed dust collector, wherein excellent
It is selected as bag filter, has the advantages that dust removing effects are preferable compared to other cleaners, take up little area.The boiler primary air fan
For centrifugal blower etc. common in boiler plant.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent process transformation made by the utility model description, it is applied directly or indirectly in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
