Abstract
The utility model relates to a boiler dust remover through centrifugal force from gaseous separation dispersion particle improves on former multicell dry cyclone basis promptly, add the steam channel of air-supply line department, waste heat utilization water tank isotructure between casing and the cyclone, and use the enamel cyclone, install the air intake baffle additional, through synthesizing the improvement, make dust collection efficiency reach 97%, the stable performance, and recoverable waste heat, the energy saving, wear-resisting anticorrosive, long service life, reduce area, installation convenient to use.
Description
The utility model relates to a kind of separator, specifically a kind of boiler dust remover that separates dispersed granules by centrifugal force from gas.
Existing advanced Industrial Boiler deduster is a kind of multitube dry type cyclone dust collectors, and a plurality of cyclones promptly are housed in its housing, is connected to air inlet pipe and pipe on the housing, and pipe is connected with air-introduced machine.Lower housing portion has ash bucket, logical cyclone on the ash bucket, and following platoon ash pipe, inside is provided with dividing plate, prevents to go here and there wind and secondary fly-up.A bracket supports housing.This deduster makes flue gas produce rotary centrifugal force after entering cyclone, dust is separated under centrifugal force and gravity effect and falls into ash bucket, and the flue gas that takes off behind the dirt is discharged by the core pipe in the cyclone, enters chimney again behind pipe, air-introduced machine.Its dust removing effects reaches as high as about 90%, but needs then more and more to be difficult to satisfy for strict day by day environmental protection.
The purpose of this utility model just provides the deduster that a kind of dust removing effects can further improve, to adapt to the needs of environmental protection development.
The utility model is to realize like this, on original multitube dry type cyclone dust collectors, at first improve inlet duct, promptly on air inlet pipe, also be communicated with a steam pipe, make and sneak into a certain amount of saturated vapor in the flue gas that enters deduster, smoke moisture is increased, grit viscosity strengthens, like this after entering cyclone, dust coalescence in rotary collision becomes bulky grain, and quality strengthens, the centrifugation of being more convenient for.Secondly, dividing plate is set, itself and housing base plate and sidewall structure closed tank at the housing middle part.There are water inlet pipe and hot-water line to be communicated with on the housing with this water tank.This formation is arranged in the water tank multi-cyclone device, and the cyclone surface obtains cooling, has formed thermograde from the cyclone center to outer surface.According to the heat sink theory of falling, grit has from the characteristic of high temperature to low temperature place migration, then makes in the dust centrifugalization in the flue gas in cyclone, is subjected to the influence in temperature field again, quicken to the migration on cyclone surface with separate.Simultaneously the water in the water tank is absorbing in the cyclone behind the heat of flue gas, and water temperature raises, and hot water is provided again, makes fume afterheat obtain recycling, and has reached energy-conservation effect.2 service behaviours that can improve deduster improve dust removal efficiency thus.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the top plan view of cyclone.
As shown in Figure 1, blast pipe is class venturi tubulose, is connected on the air inlet on the deduster housing 5.Before blast pipe throat, be communicated with steam pipe 1, can increase viscosity by the blast pipe flue gas.Be arranged side by side cyclone 4 in the housing 5, the bottom ash hole of cyclone 4 is communicated with ash bucket 7, and the core pipe 12 of cyclone is open-minded on dividing plate 13, and the flue gas after the dedusting enters the pipe 11 that joins with the housing outlet by the core pipe.Dividing plate 14 is arranged on the bottom of housing middle part, cyclone air inlet, surrounds water tank with housing base plate and sidewall.Water inlet pipe 3 is communicated with at water tank upper, and hot-water line 10 is communicated with in the water tank bottom.The ash bucket bottom ash pipe 8 that runs in, whole deduster is by 6 supportings of four angle bar frames.
For further improving the dust removal efficiency of this deduster, on cyclone, improved again, promptly dividing plate 15 is set at cyclone 4 air inlet places.Under former no dividing plate situation, the follow-up flue gas that enters produces collision with the flue gas that is introduced into and locates under the rotation status at the air inlet place, make the flue gas that is introduced into produce eddying motion at the air inlet place, thereby influenced the normal operating conditions of cyclone, dust removing effects descends.Add dividing plate, then can avoid the generation of this situation, flue gas is separated under desirable operating mode.Connect cyclone spiral case top board on the dividing plate 15, connect the spiral case base plate down, both sides one end is unsettled inwards, a termination air inlet interior plate.The width of dividing plate 15 is that the center of circle is that benchmark launches 15-25 ° of angle with dividing plate and air inlet junction for the core tube hub with cyclone, generally is advisable with about 20 °.Dividing plate is wide, then influences entering of follow-up flue gas; Narrow, prevent that then the effect of vortex is obvious inadequately.
Owing in the flue gas of Industrial Boiler, contain corrosivity pernicious gases such as sulfur dioxide, play corrosiveness for parts such as cyclones.For overcoming this point, be coated with in the inside of cyclone 4 and be shaped on one deck enamel layer, this overcoat can prevent the erosion of corrosive gas effectively, prolongs the service life of cyclone.And the wall thickness of cyclone is lowered, save metal material.Because the enamel layer appearance is highly polished, reduce the frictional resistance of air-flow process simultaneously, improved wearability.
In this device, air-introduced machine 9 is arranged between the support 6 of housing 5 bottoms, has realized the reasonable disposition of deduster and air-introduced machine, has reduced the floor space of installing and using.
The utility model is by adopting flue gas humidification structure, the endothermic water tank, cyclone installs comprehensive innovative approach such as dividing plate and inner enamel additional, make efficiency of dust collection through actual measurement up to 97%, and stable performance, and recyclable waste heat, saved the energy, wear-resisting anticorrosive, long service life, floor space is little, and is easy for installation.
