Abstract

The utility model relates to a horizontal type multi-tube dust remover, which is composed of a casing and cyclones which adopt the matrix arrangement. The included angle alpha between the shaft line of each cyclone and the shaft line of the casing is an acute angle; each cyclone is composed of an external tube and an internal tube; the side wall of each cyclone is provided with the gas inlet of the flue gas; each cyclone is evenly distributed between two partition boards; the two partition boards make the internal chamber of the horizontal type multi-tube dust remover split into three chambers, namely, a first dust settling chamber, a second dust settling chamber, and a flue gas chamber; the gas inlet is communicated with the first dust settling chamber, and a gas outlet is communicated with the flue gas chamber. The utility model has the advantages of simple structure and good dust removing effect. The horizontal type multi-tube dust remover which can efficiently avoid the secondary flying of the dust is suitable for all kinds of boilers.

Description

Horizontal multi-tube dust cleaner

The utility model relates to a kind of horizontal multi-tube dust cleaner, is applicable to boiler dusting, belongs to environment protection equipment.

At present, the whirlwind of common multi-tube dust cleaner is vertical layout, forms a dust-settling compartment, can not be controlled for the secondary fly-up of dust, thereby can not ensure dust removing effects, and it is limited particularly fine solid particle to be pounced on energy collecting power; Secondly, common multi-tube dust cleaner generally all forms the pressure water conservancy diversion by means of guide vane, form upper dust-ring easily, reduces dust removing effects, and in addition, the guide vane resistance is big especially, and guide vane is very easy to wearing and tearing, and life cycle is short.

The purpose of this utility model is at above-mentioned shortcoming of the prior art, and provide a kind of the thickness dust is done the classification processing, can avoid the dust secondary fly-up effectively, natural water conservancy diversion, the horizontal multi-tube dust cleaner that efficiency of dust collection is high.

The purpose of this utility model is to realize like this, a kind of molecular horizontal multi-tube dust cleaner of arranging by housing and matrix of whirlwind, angle α is an acute angle between the axis of each whirlwind and the axis of housing, each whirlwind is made up of outer tube and interior pipe, on the sidewall of each whirlwind, be provided with smoke air inlet, each whirlwind is distributed between two dividing plates, two dividing plates are divided into three chambers with the deduster inner chamber, promptly be positioned at first dust-settling compartment at middle part, be positioned at second dust-settling compartment of sub-ash port one end of whirlwind, be positioned at the smoke chamber of the sub-gas outlet of whirlwind one end, upper left side at housing is provided with air inlet, air inlet is connected with first dust-settling compartment, upper right side at housing is provided with the gas outlet, the gas outlet communicates with smoke chamber, the top of housing is cylindrical shape, and its lower end is an infundibulate, is first dust storage chamber below first dust-settling compartment, be second dust storage chamber below second dust-settling compartment, be provided with two ash ports in the lower end of housing.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

By Fig. 1,2 as can be known, a kind of molecular horizontal multi-tube dust cleaner of arranging by housing and matrix of whirlwind, angle α is an acute angle between the axis of the axis of each whirlwind (3) and housing (7), each whirlwind (3) is made up of outer tube (1) and interior pipe (4), on the sidewall of each whirlwind (3), be provided with smoke air inlet (2), each whirlwind (3) is distributed between dividing plate (6) and the dividing plate (13), dividing plate (6) and dividing plate (13) are divided into three chambers with the deduster inner chamber, promptly be positioned at first dust-settling compartment (14) at middle part, be positioned at second dust-settling compartment (8) of sub-ash port one end of whirlwind, be positioned at the smoke chamber (15) of the sub-gas outlet of whirlwind one end, be provided with air inlet (5) in the upper left side of housing (7), air inlet (5) is connected with first dust-settling compartment (14), be provided with gas outlet (16) in the upper right side of housing (7), gas outlet (16) communicates with smoke chamber (15), the top of housing (7) is cylindrical shape, its lower end is an infundibulate, below first dust-settling compartment (14) first dust storage chamber (12), be second dust storage chamber (9) below second dust-settling compartment (8), be provided with ash port (10) in the lower end of housing, (11).

Smoke air inlet (2) on each whirlwind (3) is the rectangle air inlet, and the air inlet of adjacent two whirlwind (3) is oppositely arranged.

The course of work of the present utility model is as follows: because flue gas forms angle of flare in import department, flow velocity reduced suddenly after flue gas entered deduster, bigger grit with self gravity and with the collision of the sub-outer tube of whirlwind after, in the first dust-settling compartment natural subsidence in first dust collection chamber, through the flue gas after the one-level processing, tangentially enter in the sub-pipe of whirlwind by the smoke air inlet on whirlwind and to do high speed rotary motion, pass through action of centrifugal force, dust is deposited to second dust-settling compartment along the sub-outer tube wall of whirlwind, fall into then in second dust storage chamber, the absolute airtight isolation of two-stage dust-settling compartment and dust storage chamber, treated dust can not get up by secondary fly-up; The flue gas that has purified enters smoke chamber by pipe in whirlwind, enters chimney through the gas outlet then.

The utility model has the advantages that simple in structure, good dedusting effect, detect through province environmental administration that smoke discharge amount is 140 milligrams/meter³, and a national class regional standard is 250 milligrams/meter³ Owing to revolve The ash port of wind forms angle with the ash that falls, and Whirlwind cyclone ash port and dividing plate (6) formation angle, revolves The following calm channelling of wind ash port can not form secondary fly-up.
