Abstract

The utility model relates to an adjustable whirlwind separator which is the boiler dedusting equipment. The main structure comprises an outer barrel, a core pipe, a conical barrel, a material storage hopper, an inlet and an outlet. The utility model is characterized in that the inlet position of the outer barrel is provided with an adjusting baffle plate, and the bottom of the core pipe is provided with an umbrella-shaped cover and an adjustable impeller whose height can be adjusted by an adjusting rod. The utility model has the advantages of reduced running resistance, improved separation efficiency, energy saving, all-purpose and wide practicality.

Description

Adjustable whirlwind separator

The utility model relates to a kind of device that gas separates with granular material that is used for, as deduster or granular material retracting device.

Along with the development of Chinese national economy, the certain areas environmental pollution is more and more serious, and the pollution of atmosphere is obvious to all especially.In order to improve environment, purify atmosphere, must the good deduster of application performance.Deduster quantity is many at present, and kind is also a lot, wherein uses the cyclone separator of dry type more generally, but existing cyclone separator, perhaps efficient is low, and perhaps resistance is big.For example, general industry enterprise uses more XCX type cyclone dust collectors now, when prototyping testing, its performance indications still can, but when using, because the variation of dust physical property, the variation that dust granules distributes, and dust enters the variation of the speed of deduster, makes the service efficiency of deduster depart from art designs efficient far away, and it also is like this that dust remover resistance changes.Some industrial production sector (for example: produce cement, medicinal powder) cyclone separator means commonly used is collected granular material, but usually because regulating measure influences efficiency separator or resistance is excessive, hinders and use, and has a strong impact on its economic benefit.Present cyclone separator both domestic and external, perhaps non-adjustable, perhaps regulating measure is improper, does not reach regulating effect.

The purpose of this utility model is a kind of cyclone separator that can conveniently regulate of design, to improve separative efficiency and material organic efficiency, reduces SR, energy savings.

The utility model adjustable cyclonic separator, partly form by outlet 2, core pipe 3, inlet 4, urceolus 6, conically shaped 9, storage bin hopper 10 etc., wherein storage bin hopper 10 is positioned at conically shaped 9 lower ends, conically shaped 9 is communicated with inlet 4 through urceolus 6, it is coaxial with urceolus and 2 be communicated with inlet that core pipe 3 is positioned at urceolus 6, feature of the present utility model is that the lower end of core pipe 3 is provided with adjustable impeller 7 and umbrella hood 8 at inlet 4 places and be provided with fender plate 5, and adjustable impeller 7 can be used with adjusting rod 1 and adjust up and down.

Baffle plate of this adjustable cyclonic separator and impeller all make adjustable, so that reach the purpose that improves separative efficiency and reduce resistance.Applicable to purifying industrial circles such as dusty gas or recovery granular material.

The operation principle of adjustable cyclonic separator is to utilize the severe of dust and gas poor, produces centrifugation by high speed rotation in whirlwind granular material is separated from gas.Mainly contain the improvement of three aspects with respect to XCX type deduster: 1, set up the inlet controllable register, can change gas flow rate by its adjusting, even also reaching certain speed, load variations guarantees that dust can separate.2, umbrella hood is established in gas vent core pipe lower end, will guide the outside into to outer tube inner wall near the powder of outlet core pipe, also eluting gas is introduced smoothly simultaneously in the core pipe and is discharged.3, adorn adjustable impeller in outlet core pipe bottom, produce eddy flow when making discharge gas flow into the core pipe and can reduce resistance, and different its resistances in the position of adjustable impeller are also different, make system's actual motion resistance minimizing, reach the purpose of energy savings.

Adjustable cyclonic separator, by fender plate, the adjusting of adjustable impeller and umbrella hood, can improve separative efficiency greatly and improve the material organic efficiency, SR is reduced reach the purpose of energy savings, advantage such as this product has highly versatile, and practicality is wide.

Fig. 1 is the structure principle chart of the utility model adjustable cyclonic separator.

Embodiment:

As shown in Figure 1: a kind of adjustable cyclonic separator comprises the fender plate 5 of cyclone separator, adjustable impeller 7 and umbrella hood 8.The fender plate of adjustable cyclonic separator, adjustable impeller and umbrella hood can be regulated at any time; Also can regulate, when reaching optimum state, be fixed up,, reduce resistance (reducing 8% approximately) simultaneously to improve separative efficiency (improving 5% approximately) in the incipient stage.

The outlet of this cyclone separator is connected with air-introduced machine, and the boiler export smoke box is connected with the adjustable cyclonic separator inlet, with the air-introduced machine suction that links to each other of outlet under flue gas flow into adjustable cyclonic separator by boiler export and enter the mouth, through fender plate 5, different exhaust gas volumns are regulated make the flue gas that enters behind the adjustable cyclonic separator can both keep certain flow velocity, flue gas flows into separator through fender plate, between urceolus and inner core, produce rotation at a high speed, ash-laden gas is rotated down, flue gas near inner tank theca runs into umbrella hood 8, make ash-laden gas be separated to outer tube inner wall, fume is prolonging outer tube inner wall and is flowing into storage bin hopper downwards, flue gas after the dedusting flows into core case (inner core), because the use of adjustable impeller produces rotating flow, and the variation of adjustable impeller height reduces the separator system resistance, and the flue gas after the dedusting flows out outlet 2.Make adjustable cyclonic separator reach the efficiency of dust collection height, be that flow resistance is little, with energy savings.
