Abstract
The utility model relates to a device used for removing solid combustion products, particularly a compound dust remover which utilizes rotational flow and electrostatic effect to separate the solid combustion product from smoke gas. A ceramic multiclone is connected in series with an electrostatic dust remover to form a secondary dust remover, and a guide tube which can make the vortex smoke gas sent from a first dust remover evenly enter the electrostatic dust remover is arranged between the ceramic multiclone and the electrostatic dust remover. Because of the adoption of the combination mode, the dust removal efficiency of the compound dust remover is more than 98.5% in general, and the cost and running cost of the dust remover are reduced and are equivalent to about one-half of those of the electrostatic dust remover. Energy saving effect is obvious, and power consumption is only about one third of that of the electrostatic dust remover.
Description
The utility model relates to a kind of device of removing the solid combustion product, particularly utilizes the complex dust collector of eddy flow and electrostatic effect separating solids combustion products from flue gas.
Though be used for the electrostatic precipitator efficiency of dust collection height that boiler dust is administered, because of one-time investment is big, need in service are established factor affecting such as personal management, power consumption are big, operating cost is higher, maintenance is cumbersome, so do not popularized and promote the use of.
Though the ceramic multicyclone that generally uses has low, the easy installation of cost, high temperature resistant, corrosion-resistant, long service life at present, advantages such as convenient management, but, generally about 90%, thereby be difficult to satisfy the requirement of higher dust removal efficiency because of efficiency of dust collection is lower.
The purpose of this utility model is to overcome the deficiency of above-mentioned existing single deduster, and a kind of efficient complex dust collector that integrates cyclone dust collectors and electrostatic precipitator advantage and be applicable to various flue dust source is provided.
Technical solution of the present utility model is: complex dust collector mainly is made up of two-stage tandem deduster, disposal box, air-introduced machine, its special character is that first order deduster is cyclone dust collectors, the second level is electrostatic precipitator, the air inlet of cyclone dust collectors is connected with the flue dust source, its gas outlet is connected with the air inlet of electrostatic precipitator through conduit, and the gas outlet of electrostatic precipitator then is connected with the passage of discharging flue gas.
The conduit that cyclone dust collectors are connected with electrostatic precipitator, its outlet is greater than inlet, be gradually open form pipe, the flue distance of conduit should reasonably be selected, if the space that cyclone dust collectors and electrostatic precipitator can have certain limit between the two, so the flue of conduit preferably select longer so that adjust flue gas.Be provided with in the pipe airflow-distribution board and or air-flow guiding distribution grid, in order to adjust flue gas, make the eddy flow flue gas that comes out from cyclone dust collectors can be evenly, balance enters in the electrostatic precipitator.The duct wall relative with ground is preferably skew wall, makes it can satisfy gradually open form, and the grit that drops in the conduit is slipped in the disposal box.
The air inlet of cyclone dust collectors is super pancake mouth, and its effect is to make the smoke distribution that enters even.
Described cyclone dust collectors are ceramic multicyclone or cast iron multicyclone, preferably adopt the 99 high-efficiency ceramic multicyclones that obtained Chinese utility model patent to match, make the utility model can obtain best effect with electrostatic precipitator.
Characteristics of the present utility model are at first to allow flue gas enter in the ceramic multicyclone, by it separation of big dust particle in flue gas is removed, and then through conduit with eddy flow flue gas uniform balance send in the electrostatic precipitator, utilize electrostatic effect, further remove the fine dust in the flue gas.
Owing to adopted above-mentioned combination, the efficiency of dust collection of this complex dust collector has reached the dust removing effects of electrostatic precipitator generally more than 98.5%.Simultaneously,, greatly reduce the cost of deduster, be equivalent to about 1/2nd to 3/5ths of electrostatic precipitator approximately because of adopting ceramic multicyclone as primary dust removing; Safeguard that simply its maintenance workload only is about 1/3rd of an electrostatic precipitator; Energy-saving effect is remarkable, and power consumption only is about 1/3rd of an electrostatic precipitator, has reduced operating cost, remarkable in economical benefits.This deduster is suitable for various coal-burning boilers and various flue dust source.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model conduit.
Fig. 3 is the structural representation of the another kind of form of the utility model conduit.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, complex dust collector is to be made of the two-stage tandem deduster, and first order deduster is ceramic multicyclone (1), and the second level is electrostatic precipitator (2), is connected by conduit (3) between the two.The air inlet (4) of pottery multicyclone is super pancake, and it is connected with the flue dust source.The gas outlet of electrostatic precipitator (5) then is connected through the passage of air-introduced machine with the discharging flue gas.(6) be the disposal box of deduster.The inside formation of pottery multicyclone and electrostatic precipitator and principle and prior art are basic identical, and concrete technical parameter should design according to supporting boiler.
Fig. 2 has provided a kind of version of conduit, and promptly the flue of conduit distance is longer, is convenient to fully adjust flue gas.This structure is suitable for the first order and second level deduster and has occasion than large space between the two.The inlet of conduit is connected with the gas outlet of ceramic multicyclone.The outlet of conduit is connected with the air inlet of electrostatic precipitator.The corner of conduit (3) is provided with air-flow guiding distribution grid (7), and it is a hole grid plate.Be provided with airflow-distribution board (8) near the conduit outlet place, it is a perforated flat plate, its pore size difference everywhere, and it is determined according to the size that can produce resistance.And one section duct wall being positioned at exit relative with ground be for gradually opening skew wall (9), so that be connected with the electrostatic precipitator air inlet, and the grit that falls within the conduit can be slipped in the disposal box in the electrostatic precipitator.
Fig. 3 has provided the another kind of version of conduit, and this conduit is suitable for having between the two-step filter occasion in less space.Conduit (3) is tubaeform, and its inlet directly links to each other with the electrostatic precipitator air inlet is corresponding with the gas outlet of ceramic multicyclone with outlet.The airflow-distribution board (8) that is provided with in the conduit is a perforated flat plate, the difference of pore size everywhere of plate.
Claims (2)
1, a kind of complex dust collector, mainly form by two-stage tandem deduster, disposal box, air-introduced machine, it is characterized in that first order deduster is cyclone dust collectors, the second level is electrostatic precipitator, the air inlet of cyclone dust collectors is connected with the flue dust source, its gas outlet is connected with the air inlet of electrostatic precipitator through conduit, and the gas outlet of electrostatic precipitator then is connected with the passage of discharging flue gas.
