Description
Technical field
The utility model relates to a kind of low temperature dust-laden tail gas online ash removal dust arrester, belongs to low temperature exhaust heat recovery technology field.
Background technology
Along with further going deep into of energy-saving and emission-reduction policy, the waste heat of some low temperature (temperature is about 400 ℃) dust-laden tail gas has obtained utilization, when utilizing these tail gas, and the following problem of ubiquity:
1, owing to have amounts of dust in the tail gas, the character of various dust is different, causes the heating surface tube dust stratification serious, has seriously hindered waste heat recovery; For example: contain a large amount of silica dusts in the avasite heating furnace flue, cause fouling of heating surface serious, existing waste heat boiler all can not normally put into operation.
2, owing to contain amounts of dust in the tail gas, especially to low temperature exhaust gas, waste heat boiler can not adopt extended surface, and boiler arranges that heating surface is big, and boiler structure is huge; For example: rotary hearth furnace waste heat flue gas can be separated out a kind of oily matter when low-temperature zone, increases the heat exchange thermal resistance, causes heating surface huge.
3, dust arrester commonly used is set between waste-heat recovery device, for example: gravity or cyclone dust collectors inferior separating effect, the electric dust-removing equipment investment is big, temperature drop is big, and the sack cleaner heatproof is not high; And all there is the big problem of equipment resistance in these equipment; Can't handle for cohesiveness and adsorptivity ash, need regular blowing out cleaning.
If can effectively address these problems,, produce bigger economic and social benefit with the UTILIZATION OF VESIDUAL HEAT IN that further promotes low temperature dust-laden tail gas.
The utility model content
The utility model provides a kind of low temperature dust-laden tail gas online ash removal dust arrester to the deficiency of prior art, under the prerequisite that does not influence the low temperature exhaust gas waste heat, removes most of dust in the tail gas, guarantees waste-heat recovery device safety, normal operation.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of low temperature dust-laden tail gas online ash removal dust arrester comprises being the furnace wall that cavity is provided with that said furnace wall is provided with furnace wall and advances mouth and furnace wall outlet flue; Also comprise netted dust trapping device; This netted dust trapping device advances the mouth setting near furnace wall; Said netted dust trapping device comprises netted dust lane, drive unit, driving wheel and the driven pulley of catching; Said driving wheel and driven pulley relatively are supported on the outside of furnace wall respectively through support, and driving wheel is connected with the output of drive unit; Netted periphery of catching dust lane around driving wheel and driven pulley; Driving wheel and driven pulley place in the annular seal space wall sealing-in of sealing chamber and furnace wall simultaneously.
The inwall of the annular seal space of said driven pulley side is connected with dust cleaner, and this side seal chamber is provided with except that cinder notch.
Said cleaning plant is a steel brush, and the brush of steel brush is caught the dust lane setting towards netted; Perhaps said cleaning plant is the high pressure water washing device, and the shower nozzle of this high pressure water cleaning device is installed in the inwall of annular seal space; Perhaps said cleaning plant is the compressed air rinsing device, and the shower nozzle of this compressed air rinsing device is installed in the inwall of annular seal space.
The said netted dust lane of catching adopts the filter course of being made up of multi-layer silk screen to constitute; This netted dust lane of catching is perpendicular to the flow of flue gas direction setting in the furnace wall.
According to above technical scheme, can realize following beneficial effect:
1, cohesiveness and adsorptivity ash in the online removing tail gas, assurance device moves continuously, guarantees economic and social benefit;
When 2, flue gas was through this device, the flue gas temperature drop was little, generally is no more than 10 ℃;
When 3, flue gas was through this device, flue gas resistance was little, generally is no more than 300Pa;
4, under the situation of not blowing out, cohesiveness in the tail gas and adsorptivity ash are removed, and the temperature drop of tail gas is little, resistance drop is little.
