Abstract
The utility model discloses a spiral-guide cyclone duster, relating to environmental protection equipment, which comprises a cyclonic collection tube and the core tube of the cyclonic collection tube. Because entering dusty gases has the phenomenon of series flow and the effect of dust removing is not ideal, a large draught fan is replaced in order to achieve the exhausting standard of dust removing. The utility model is designed and manufactured aiming at the defect that the inner wall of the cyclonic collection tube and the outer wall of the core tube of the cyclonic collection tube are cast with spiral line grooves of the same spiral direction with a definite spiral guiding angles in order to prompt the dusty gases to process regularly from top to bottom. Then the phenomenon of series flow is avoided; the force resistance is reduced relatively; the centrifugal force of the dusty gases in the cyclonic collection tube is enlarged; the ideal effect is achieved. The effect of dust removing can be reached 95-99% through experiment. The spiral-guide cyclone duster is an ideal duster for boilers and furnaces.
Description
The utility model relates to a kind of environmental protection equipment.
Many cleaners are introduced and developed to China recent years aspect improvement boiler smoke, granular material transportation and Industrial Stoves dust.On the cyclone dust collectors basis, developed utility model patent, the patent No.: 86204924, high-efficiency dust remover.With reference to Fig. 1, this deduster mainly contains ironcasting whirlwind and 1. reaches the sub 2. composition of managing of whirlwind that steel pipe is made.It can be according to the size of removing dust quantity, is assembled in the casing of welded steel plate is 4. interior by the high-efficiency dust remover of a plurality of monomers and forms the large-tonnage deduster, reaches dust removing effects.Its working method is: flue dust is under the effect of air-introduced machine, flue dust screws in the whirlwind chamber 1. along whirlwind tangential admission mouth 1., under the effect of rotary centrifugal force, dust falls into the bottom of whirlwind truncated cone section 1., 3. 2. the gas that has purified enter the purified gas blast pipe through whirlwind pipe, extract out by air-introduced machine, reach the purpose of udst separation gas.Learn through the productions in several years and user profile feedback: dusty gas is entering in the sub-chamber of whirlwind in the udst separation process, it is big that resistance becomes, dusty gas centrifugal force does not reach designing requirement, and indivedual class districts still do not reach the national regulation dust emission standard, need use big air-introduced machine instead; It is short to find also in the use that 2. whirlwind manages the life-span, can not be synchronous with the sub-life-span of whirlwind.
The purpose of this utility model is:
1: under the situation that does not strengthen air-introduced machine, reduce the resistance after dusty gas enters whirlwind, improve efficiency of dust collection:
2: make the sub-life-span trend of whirlwind pipe and whirlwind synchronously.
The purpose of this utility model is achieved in that the design principle according to cyclone dust collectors is that dust-contained airflow is rotated, and by centrifugal force, flue dust is cut apart.From formula as can be known:
F = (m·v
2)/(R)
---centrifugal force m---quality in the formula: F
V---flow velocity R---radius
Selected as R, dustiness is constant in the gas, when flow velocity V strengthens, could improve centrifugal force F.Only in this way could further remove little grit, reach the purpose of Purge gas.The utility model is that the change in flow when making dusty gas flow through deduster is little under the constant situation of air-introduced machine.Promptly the inwall direct casting at whirlwind is shaped on the helix guide groove, casting is shaped on the same rotation direction of whirlwind too on the external diameter surface of the sub-pipe of whirlwind, helix guide groove with angle, make dusty gas in whirlwind along the well-regulated precession from the top down of helix guide groove, solved dusty gas crossfire phenomenon in the sub-chamber of whirlwind, thereby reduced the resistance of dust-contained airflow, strengthened centrifugal force, played the purpose of further Purge gas.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 2 is spirally-guided cyclone dust collectors profiles.
Describe in detail according to concrete deduster and the working condition that the utility model proposes below in conjunction with Fig. 2:
The spirally-guided cyclone dust collectors mainly contain whirlwind 1. and be contained in whirlwind 1. inner chamber 2. reach with the sub-core pipe of whirlwind of the same axis of whirlwind and be contained in the purified gas fairlead that 2. the sub-core pipe of whirlwind go up and 3. form.1. whirlwind is ironcasting, it is characterized in that outer shape is that epimere is a slender cylinder, and hypomere is the truncated cone body, and air inlet on the slender cylinder section and slender cylinder section are tangent.Inwall is shaped on 28 degree---and the helix groove of 32 degree spiral lead angles, rotation direction be according to the sub-air inlet direction of whirlwind difference, divides two kinds of left-handed, dextrorotation.2. the sub-inner core tube of whirlwind is nodular iron casting, it is characterized in that an end has the tubular cylinder of flange, is shaped on equipped together whirlwind 1. the helix groove and the rotation direction of same-handed lead angle on the outer cylinder surface, and inner cylinder face is a shiny surface.3. the purified gas fairlead is steel pipe or iron sheet product.
Its dedusting work is performed such: purifying tracheae 3. under the effect of terminal air-introduced machine, dusty gas is gone in the sub-chamber of whirlwind by whirlwind tangent air inlet 1., owing to be shaped on the helix groove of same-handed lead angle on inwall and the sub-core pipe of the whirlwind external cylindrical surface 2., make the dusty gas that tangentially enters along the precession from the top down of helix groove, in the precession process, under action of centrifugal force, air and dust are cut apart.
The spirally-guided cyclone dust collectors of monomer can be handled the size of fume amount according to need, can a plurality ofly be assembled in the casing, and type becomes the deduster of all size.
Advantage of the present utility model is whirlwind, and 1. inwall and the sub-core pipe of whirlwind outer wall 2. all are shaped on the helix groove of the same rotation direction of certain spiral lead angle, under the effect of air-introduced machine, enter the well-regulated precession from the top down of dusty gas in the spirally-guided cyclone dust collectors, avoided the crossfire phenomenon of dusty gas in deduster, promptly reduced the precession resistance of dusty gas in whirlwind relatively, strengthened centrifugal force, impelled cutting apart of fine flue dust and air, improved the purifying rate of dusty gas, obtained under the situation that does not strengthen air-introduced machine, obtain higher dust removing effects, can reach 95-99% through the test dust removing effects.Moreover, because the sub-core pipe of whirlwind is made by spheroidal graphite cast-iron, substituted in the past used seamed steel pipe, it and sub-life-span of whirlwind have been reached synchronously, improved machine life, help producing and maintenance.
Claims (3)
1, a kind of spirally-guided cyclone dust collectors of being made up of whirlwind and the sub-core pipe of whirlwind is characterized in that all being shaped on spiral grooves on the inwall of slender cylinder section of ironcasting whirlwind and on the outer wall of the sub-core pipe of nodular iron casting whirlwind.
2, according to the described spirally-guided cyclone dust collectors of claim 1, it is characterized in that the helix groove on the inwall of the careful elongated cylinder section of described whirlwind is the helix groove of the spiral lead angle of 28-32 degree, rotation direction according to the opening direction of the sub-tangent air inlet of whirlwind be divided into left-handed to, dextrorotation to two kinds.
3,, it is characterized in that the helix groove has identical spiral lead angle and rotation direction on helix groove and the equipped mutually sub-inwall of whirlwind on the sub-core tube wall of described whirlwind according to the described spirally-guided cyclone dust collectors of claim 1.
