Abstract

The utility model relates to a cyclone dust collector for carrying out gas-solid separation on dust-contained gas generated in the fields of metallurgy, chemical industry, environmental protection and the like, especially blast-furnace gas. The utility model is characterized in that a vertical guide plate (4) is arranged in a cyclone chamber (7) of the dust collector; by the combined action of the vertical guide plate (4) and a guide cone (3), the dust-contained gas generates axial speed and tangential speed, and thereby, the goal of dust and gas separation is achieved. The cyclone dust collector has novel arrangement mode of the guide plate and has high efficiency of the equipment dust collector and can effectively reduce the dust content in effluent gas, reduces environmental pollution, simultaneously lowers the load of subsequent dust removal installations and reduces the investment and operating cost.

Description

A kind of cyclone dust collectors
Technical field
The utility model belongs to technical field of separating operation, discloses a kind of cyclone dust collectors.Be used for containing dusty gas, especially blast furnace gas, carry out gas solid separation what fields such as metallurgy, chemical industry, environmental protection produced.
Background technology
Now, environmental issue has become worldwide problem.Air pollution index also becomes day by day and instructs people's daily life important information.The concentration of overall suspended pellet has also become an important indicator weighing air pollution index in the air.At the problem that how to reduce airborne suspended particulate substance, the especially control of field dust emissions such as metallurgy, chemical industry, we have done a large amount of work.The input of device such as laying dust device, washer makes dusty gas enter atmosphere and has obtained effective purification before, for environmental protection cause has been made outstanding contribution.The deduster that is used to carry out gas solid separation at present mainly contains gravitational precipitator, cyclone dust collectors, scrubbing tower, sack cleaner etc., and its dust collector efficiency also is not quite similar.Advantages such as cyclone dust collectors are little with its good efficiency of dust collection, floor space, small investment are day by day by extensive studies and application.Cyclone dust collectors mainly are divided into axial cyclone dust collectors and two types of tangential cyclone dust collectors at present.Though cyclone dust collectors have plurality of advantages, also there are several common problems, deflector and air deflector housing serious wear, perhaps eddy flow arm, eddy flow arm and cylindrical shell junction serious wear.The equipment operation, the maintenance cost that bring thus also will increase.
The utility model content
The purpose of this utility model overcomes the deficiencies in the prior art exactly, proposes a kind of cyclone dust removal apparatus.It is little that resistance during the utility model airflow passes deflector undermines impact, and equipment dust collector efficiency height can effectively reduce the dust content in the eluting gas, reduces environmental pollution, reduces the load of follow-up dust removal installation simultaneously, reduces investment operating cost.Be used for containing dusty gas, especially blast furnace gas, carry out gas solid separation what fields such as metallurgy, chemical industry, environmental protection produced.
The utility model adopts technical scheme as follows: the cyclone dust removal apparatus comprises air inlet pipe, rotational flow dust-removing chamber, reflection cone and blast pipe, it is characterized in that: deflector and guiding cone are set in the spin chamber of deduster; Described deflector is vertical shape; Deflector and horizontal plane angle are 20 °~75 °; Guiding cone and horizontal plane angle are 20 °~75 °; Deflector is evenly arranged on spin chamber's circumference; The quantity of deflector is 4~30; The reflection cone is set in described storeroom, and reflection cone and horizontal plane angle are 45 °~75 °.
Dusty gas is through air inlet pipe, enter the spin chamber, acting in conjunction by guiding cone, deflector, make air-flow produce tangential and axial speed, enter the rotational flow dust-removing chamber, the grit in the air-flow moves to tube wall of dust settler because of centrifugal action, and glides at the effect lower edge of deadweight and air-flow barrel, the dust of assembling finally falls into the storeroom of bottom, carries out ash discharge by ash discharge chamber is set.Air-flow then alters course under the effect of reflection cone, and rotational gas flow in the formation (interior eddy flow) is discharged by middle blast pipe.

Fig. 4 is the vertical view of the utility model structure coldplate.
Fig. 5 is the right view of the utility model structure coldplate.
Among the figure: part 1 is a dusty gas; Part 2 is an air inlet pipe, and part 3 is a guiding cone, part 4 deflectors, and part 5 is the rotational flow dust-removing chamber, and part 6 is a storeroom, and part 7 is the spin chamber, the dust of part 8 for assembling, part 9 is a blast pipe, and part 10 is last rotational gas flow, and part 11 is the reflection cone.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure: the utility model is made up of air inlet pipe 2, rotational flow dust-removing chamber 5, spin chamber 7, storeroom 6 etc., and deflector 4 and guiding cone 3 are set in spin chamber 7.Deflector 4 is vertical shape and horizontal plane angle at 45, and deflector 4 arranges evenly that on spin chamber's 7 circumference the quantity of deflector is 24; The vertical shape design of deflector 4, the resistance after having reduced air-flow and deflector 4 contacting undermines frontal impact; Deflector 4 makes air-flow have tangential velocity on the one hand, makes dust produce centrifugal force, makes air-flow produce axial velocity on the other hand, and air-flow and dust are moved downward.Guiding cone 3 is 30 ° with horizontal plane angle, and steering current moves downward.Reflection cone 11 is set in storeroom 6, and reflection cone 11 is 60 ° with horizontal plane angle, and steering current moves upward; Last rotational gas flow 10 is discharged from blast pipe 9.
Dusty gas 1 is through air inlet pipe 2, enter spin chamber 7, acting in conjunction by guiding cone 3, deflector 4, make air-flow produce tangential and axial speed, enter rotational flow dust-removing chamber 5, the grit in the air-flow moves to tube wall of dust settler because of centrifugal action, and glides at the effect lower edge of deadweight and air-flow barrel, the dust of assembling 8 finally falls into the storeroom 6 of bottom, carries out ash discharge by ash discharge chamber is set; Air-flow then alters course under the effect of reflection cone 11, and rotational gas flow 10 in the formation (interior eddy flow) is discharged by middle blast pipe 9.
The utlity model has cleaning, environmental protection, efficient advantage. To contain at present the especially effective cleaner of blast furnace gas of dusty gas.
