Description

A kind of biomass boiler dust pelletizing system flying dust recovery system
Technical field
It the utility model is related to pollution utilization technology field, and in particular to a kind of biomass boiler dust pelletizing system flying dust Recovery system.
Background technology
It is well known that energy-saving and emission-reduction, low-carbon economy, environmental protection are the very urgent cardinal tasks in the world today, relation To the existence and expanding economy of the mankind.Reform and opening-up the development of China's every profession and trade has been driven into fast traffic lane, in recent years light industry, The industry developments such as weaving, chemical industry quickly, have become and use energy rich and influential family, are also discharged while mass energy is consumed to surrounding environment Go out substantial amounts of waste residue, waste gas, waste water, used heat, these emissions it is extremely serious pollute our living environment, while also make The about paces of national sustained economic development.The industries such as light industry, weaving, chemical industry provide the boiler of personal thermoelectricity in " energy-saving and emission-reduction " Aspect has huge potentiality to excavate, and by technological innovation, backward waste discharge technique is eliminated, using advanced energy-conservation work Skill, it is possible to give full play of the very big efficiency of the energy, to save the energy, environmental protection contributes.
Electrostatic precipitator is the cleaner for being come out the dust in gas or drop separation using electrostatic force (Coulomb force), Also referred to as electric cleaner, cottrell.Electrostatic precipitator obtains in the industry such as smelting, cement, coal gas, sulfuric acid, papermaking, coal-burning power plant Extensive use is arrived.Distinguishing feature of the electrostatic precipitator compared with other types deduster be:Almost to various dust, smog Deng until subparticle has high efficiency of dust collection;It can also be applied even if high temperature and high pressure gas;Equipment crushing is small;Energy consumption is low; Safeguard and maintenance is all relatively simple;Operating cost is low.In view of its advantage is numerous, and with the equipment requirement of coal-burning power plant extremely Match somebody with somebody, so electrostatic precipitator technology is introduced into after the country, become the standard configuration equipment of vast coal-burning power plant.There is substantial amounts of section Grind, school, enterprise are directed to the correlative study of electrostatic precipitator, promoted the application development of electrostatic precipitator.But electrostatic removes Dirt device is very limited for fine particle removal ability, still has a large amount of fine grained flying dusts to enter environment after electrostatic precipitation, causes dirt Contaminate and influence human health.Reason is that fine particle flue dust composition is mostly osmanthus mistake matter mineral, and its high specific resistance characteristic causes Removal efficiency is low, and the " secondary droplets " problems that mechanical vibrator triggers, all causing flying dust can not be trapped by electrostatic precipitator completely, And disadvantages mentioned above is also exactly the problem of flying dust recovery system is difficult to overcome in biomass boiler dust pelletizing system.
Utility model content
The purpose of this utility model is to provide a kind of biomass boiler dust pelletizing system flying dust recovery system.
What the purpose of this utility model was realized in:
A kind of biomass boiler dust pelletizing system flying dust recovery system, including boiler flue, secondary combustion chamber, tail gas control system Unite, trough plate is installed in described boiler flue, straggly to be placed in boiler flue both sides, boiler flue passes through alumina material The pipe connecting secondary combustion chamber made, burning-point is provided with second-time burning room, secondary combustion chamber is connected with tail gas control system, tail Gas control system includes three sections of condenser pipes, a filtration system, and described filtration system is filtered by the three-level for being connected with electrostatic Net is formed.
Described trough plate is made up of polyurethane foam.
Three sections of described condenser pipes are roundabout to be placed in exhaust gases passes.
Described three-level sieve meshes aperture is sequentially reduced along flow of flue gas direction.
Also include electrode group plywood in described flue and the high voltage package of negative high voltage, electrode combination are provided to electrode group plywood Plate is fixed on the support plinth in flue and is electrically connected with high voltage package.
The electrode group plywood is Carbon fibe conductive electrode plate or metal electrode board.
Described secondary combustion chamber is provided with backboard, and air inlet is provided with backboard.
The beneficial effects of the utility model are:
The utility model coordinates negative high voltage electrostatic precipitation filter screen, so as to realize to entering by designing brand-new air channel structure The flue gas for entering flue is first filtered, then carries out effective second-time burning;Flue gas has not only been purified, while has prevented dust and cotton-shaped Thing influences the service life of boiler, and electrostatic filter screen is realized to the effective net of the pollutants such as dust by electrostatic precipitation and laying dust filter screen Change;Electrostatic filter screen includes three layers, bulky grain dust in air etc. tentatively can be filtered, to improve electrostatic precipitator With the service life of filter screen.
Brief description of the drawings
Fig. 1 is overall structure figure of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the circulating direction of flue gas is shown in arrow, the utility model includes boiler flue 1, secondary combustion chamber 2nd, tail gas control system 3, trough plate 4 is installed in described boiler flue, it is straggly to be placed in boiler flue both sides, boiler flue The pipe connecting secondary combustion chamber made by alumina material, burning-point 5, secondary combustion chamber and tail gas are provided with second-time burning room Control system connects, and tail gas control system includes three sections of condenser pipes 6, a filtration system 7, described filtration system by The three-level filter screen for being connected with electrostatic is formed.The utility model is provided with trough plate by brand-new Flue duct design in flue, first Dust processing is shunted and obstructed to flue gas, then by secondary combustion chamber by gases such as the sulfide in flue gas, nitride Burning-up makes flue gas after not cooled down finally by condenser pipe by electrostatic filter screen, filter screen is set by three-level can absorb more than 95% Flying dust, be finally reached the purpose of purifying smoke.
In order to strengthen the effect of the gear of trough plate ash and improve service life, described trough plate is by polyurethane foam structure Into.
Three sections of described condenser pipes are roundabout to be placed in exhaust gases passes, is ensured that the flue-gas temperature after cooling reduces, is closed simultaneously Reason carries out recuperation of heat using the heat of flue gas.
Described three-level sieve meshes aperture is sequentially reduced along flow of flue gas direction, is made first by the filter screen of maximum diameter of hole Bulky grain flying dust in flue gas is filtered, and is then filtered the less flying dust of particle successively, compared to one layer filter screen of the design, is risen Arrive that guarantee flue is unimpeded, rationally purified the purpose of flying dust.
In order to further strengthen the net gas ability of flue, electrode group plywood 8 is also included in described flue and to electrode group Plywood provides the high voltage package of negative high voltage, and electrode group plywood is fixed on the support plinth in flue and is electrically connected with high voltage package.
