Description
Technical field
Field of sanitation is the utility model is related to, particularly relates to a kind of biomass fuel boiler dust pelletizing system.
Background technology
Biomass fuel boiler is one of existing boiler for carrying out using, because its fuel uses biological particles, pollutant
It is relatively fewer, but it is increasingly strict with environmental requirement, and particulate matter can exceed discharge standard in the tail gas of the boiler emission, because
This need to be equipped with corresponding dust pelletizing system.
Boiler exhaust gas is due to its high temperature and containing Mars, and frequently with Water spray dedusting, the technique can not only produce
Substantial amounts of sewage（Sludge containing ash content）, and the qualified discharge requirement of longtime running can not be ensured.According to sack cleaner
As unique processing equipment, although can ensure that qualified discharge, due to may result in cloth bag containing Mars in boiler exhaust gas
Burn, influence it is safe to use, simultaneously because flue-gas temperature is higher and contains certain sulphur component, after boiler down in deduster
Temperature reduce, easily cause condensation（Paste bag）, cause sack cleaner can not normal operation.If existing processing system is set
Standby exception then requires boiler down, not only influences boiler for producing operation, also results in the unnecessary start and stop damage of boiler.
Utility model content
The purpose of this utility model is to provide a kind of biomass fuel boiler dust pelletizing system, and it can guarantee that clean-up effect,
And stable and safe in operation.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of biomass fuel boiler dust pelletizing system, it includes admission line, cyclone dust collectors, sack cleaner, centrifugation
Blower fan, discharge tube, the air inlet of the cyclone dust collectors are connected with the end of admission line, and the front end of admission line is used to lead to
Enter waste gas, adjusting air valve, the air outlet of the cyclone dust collectors and the air inlet of sack cleaner are provided with the admission line
It is connected, the gas outlet of the sack cleaner is connected with the air inlet of centrifugal blower, the air outlet of the centrifugal blower and discharge
Pipeline is connected；The sack cleaner includes casing and dust-removal cloth-bag.
Cold blast sliding valve is provided between the front end of the admission line and adjusting air valve.
The material of the dust-removal cloth-bag is PTFE.
The casing of the sack cleaner is provided with insulation material.
After said structure, during utility model works, the waste gas of biomass fuel boiler is led to by admission line
Enter cyclone dust collectors, cyclone dust collectors are separated the Mars in waste gas and part big dust particle by centrifugal action from waste gas
Out, preliminary purification is carried out；Then waste gas is passed through sack cleaner filter small particles dust again, carries out deep purifying；Finally lead to
Centrifugal blower is crossed to discharge from discharge tube.Therefore the utility model realizes biomass by cyclone dust collectors and sack cleaner
The two-step purification of the waste gas of fuel boiler, it ensure that clean-up effect, and the Mars gone by cyclone dust collectors in removing exhaust gas, energy
Avoid the dust-removal cloth-bag of sack cleaner from being burnt because of Mars, ensure the utility model stable and safe in operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
As shown in figure 1, the utility model discloses a kind of biomass fuel boiler dust pelletizing system, it include admission line 1,
Cyclone dust collectors 2, sack cleaner 3, centrifugal blower 4, discharge tube 5, the air inlet and admission line of the cyclone dust collectors 2
1 end is connected, and the front end of the admission line 1 is used to be passed through waste gas, and adjusting air valve 11, institute are provided with the admission line 1
The air outlet for stating cyclone dust collectors 2 is connected with the air inlet of sack cleaner 3, the gas outlet of the sack cleaner 3 and centrifugation
The air inlet of blower fan 4 is connected, and the air outlet of the centrifugal blower 4 is connected with discharge tube 5；The sack cleaner 5 includes case
Body and dust-removal cloth-bag.
During utility model works, the waste gas of biomass fuel boiler is passed through cyclone dust collectors 2 by admission line 1, rotation
Wind deduster 2 is separated the Mars in waste gas and part big dust particle by centrifugal action from waste gas, is carried out preliminary
Purification；Then waste gas is passed through the filter small particles dust of sack cleaner 3 again, carries out deep purifying；Last waste gas is by centrifuging wind
Machine 4 is discharged from discharge tube 5.
The utility model realizes the two of the waste gas of biomass fuel boiler by cyclone dust collectors 2 and sack cleaner 3
Level purification, ensure that clean-up effect, and the Mars gone by cyclone dust collectors 2 in removing exhaust gas, is avoided that sack cleaner 3
Dust-removal cloth-bag burns because of Mars, ensures the utility model stable and safe in operation.
Further, to avoid because the temperature of waste gas is too high, reach dust-removal cloth-bag can burning-point, cause dust-removal cloth-bag to damage
Ruin, cold blast sliding valve 12 is additionally provided between the front end of the admission line 1 and adjusting air valve 11, cold wind is passed through by cold blast sliding valve 12 to drop
The temperature of low waste gas；Can also adjust cold blast sliding valve 12 and adjusting air valve 11 reach biomass fuel boiler waste gas discharge capacity with
Exhaust air rate of the present utility model reaches balanced, avoids the excessive heat for extracting biomass fuel boiler, wastes fuel.When this practicality
When a kind of new biomass fuel boiler dust pelletizing system needs maintenance, adjusting air valve 11 can be closed and will be given birth to by cold blast sliding valve 12
The waste gas of biomass fuel boiler is passed through in other cleaners, need not thus require that biomass fuel boiler is shut down, Bu Huiying
Biomass fuel boiler production run is rung, will not also cause boiler to be damaged because of start and stop.
Due to not only there was only dust in waste gas, waste gas may also have corrosivity, to ensure the use of sack cleaner effect
Fruit and life-span, the dust-removal cloth-bag of the sack cleaner 3 use high-temperature resistant anti-corrosive material, it is preferable that the material of the dust-removal cloth-bag
Expect for PTFE.
Under avoiding, because biomass fuel boiler is shut down suddenly, causing the temperature in the casing of sack cleaner 3 unexpected
Drop causes dust-removal cloth-bag to condense；The casing of the sack cleaner 3 is provided with insulation material 31, can slow down biomass fuel boiler
Shut down the decrease speed of the temperature in rear box.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
