Abstract
The utility model relates to an anti-abrasive conical regulating valve of an annular gap scrubber. The conical regulating valve is arranged in the annular gap scrubber and internally provided with a regulating rod. The conical regulating valve is characterized in that a honeycomb structure is formed on the outer wall face of the easy-to-abrade area below the throat at the upper half part of the conical regulating valve; the honeycomb structure is formed by a plurality of grooves which are connected through reinforcing plates. The anti-abrasive conical regulating valve is simple in structure and easy to manufacture and has the advantages that the direct friction between the smoke and the pipe wall is avoided; the service life of the regulating valve is greatly prolonged; the scrubbing effect is guaranteed; the normal operation of equipment in repair cycle is guaranteed.
Description
Technical field
The utility model relates to a kind of wash mill for dust-containing airflow dedusting pressure regulation, particularly the annular gap scrubber taper modulating valve in a kind of metallurgy industry coal gas dust removal of converter technique.
Background technique
In the pneumatic steelmaking dust pelletizing system, annular gap scrubber is the nucleus equipment of wet dedusting.Converter gas through the supersaturation spray tower will for thick dedusting after, with the speed of about 100m/s, enter the dedusting of annular gap scrubber essence.To enter aditus laryngis speed larger due to flue gas, and form certain corner cut with the taper modulating valve, and the taper modulating valve very easily is subject to the erosive wear of flue dust and damages, and affects dust removing effects, even that modulating valve is worn out, makes its loss of pressure regulatory function.
Although annular gap scrubber has been done meticulous consideration in design, make its interior flow field comparatively even, non-dedusting drag losses is less, and still there are the zone that the angle of shock is higher in the inlet stream at its aditus laryngis place and inner cone wall.Because the entrance dust content of gas is high, particle diameter and kinetic energy are large, and the shock zone rate of wear is exceedingly fast.The technique of steel-making dedusting has determined to the taper modulating valve, to process and replacing in stove when maintenance labour, and the speed of Crack Extension has been accelerated in the continuous wearing and tearing of certain location like this.
Thus, the impact that the zone that the taper modulating valve is positioned at the aditus laryngis place very easily is subject to the aditus laryngis air-flow, even Wear-resistant Treatment has been done on surface, can not stand the erosive wear of high speed dust-contained airflow for a long time.The continuity of STEELMAKING PRODUCTION has determined to repair in time or to change the taper modulating valve simultaneously, in case the taper modulating valve is worn out, can greatly reduce dust removal efficiency, also causes serious potential safety hazard.
The model utility content
The technical problems to be solved in the utility model: the above-mentioned defect that overcomes prior art, a kind of annular gap scrubber abrasionproof taper modulating valve is provided, can avoid flue dust directly and wall friction, thereby guarantee that the equipment in the repair cycle normally moves the working life of improving modulating valve.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Annular gap scrubber abrasionproof taper modulating valve, the taper modulating valve is placed in annular gap scrubber, and the taper modulating valve is built-in with adjustable lever; It is characterized in that: under upper half part aditus laryngis of taper modulating valve, regional outer wall easy to wear forms the cellular structure that a plurality of grooves are connected by gusset.
By technique scheme, on the same level height layer, between each groove along the even interval of tapered circumference direction, between each groove by link of boards; Along same generatrix direction, groove is diffusion type from top to bottom to be arranged, and between the upper and lower layers groove by link of boards.
By technique scheme, described groove is rectangular recess.
By technique scheme, on each level height layer, be evenly arranged 6-20 groove.
By technique scheme, described cellular structure and taper modulating valve outer wall integrally casting form.
With respect to prior art, the utlity model has following advantage:
The utility model adopts the method for casting processing, in cellular mechanism of being gathered by a plurality of rectangular recess connections of upper half part wall generation of taper modulating valve.Simple in structure, be easy to manufacture.After aditus laryngis place flue dust contact scouring water, be easy to sedimentation; tiny grit can be collected at inside grooves gradually; even groove is filled up to grit, wash away afterwards the grit come and only with groove internal surface grit, rub, grind off a part of follow-up grit and supplement into again.Go round and begin again like this, avoided flue dust directly and tube wall rubs.Greatly extend the working life of taper modulating valve, guaranteed washing effect, because modulating valve can be regulated the converter mouth micro-pressure-difference, this technology has also guaranteed normally carrying out of converter production.Due to the extensive use of circumferential weld dedusting technology in every profession and trade, this technology can be generalized to except metallurgy industry other places every field, obtains larger economic benefit and social benefit.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Below in conjunction with Figure of description explanation embodiment.
In Fig. 1 and 2, adjustable lever 1 is placed in taper modulating valve 6, and taper modulating valve 6 is placed in annular gap scrubber shell 5; In Fig. 2 taper modulating valve schematic diagram, find out that easily the regional modulating valve surface that is positioned at the aditus laryngis place of prior art is the light face; In annular gap scrubber shell 5, the dust that impact force is larger and cone Surface Contact easily produce friction.
Fig. 3 is taper modulating valve schematic diagram of the present utility model, and the zone easy to wear that often suffers the erosion of high speed dust-contained airflow under taper modulating valve 6 aditus laryngis is cast as by this section conical surface the cellular structure that groove 2 is connected with gusset 3 intervals; The same level height, along the even interval of tapered circumference direction, connected by gusset 3 between each groove 2 between each groove 2; Along same generatrix direction, each groove 2 is diffusion type from top to bottom to be arranged, and by gusset 3, is connected between upper and lower layers groove 2.
In order to be easy to make, the utility model adopts the method for casting processing, and regional outer wall easy to wear produces the rectangular recess 2 be connected one by one under upper half part aditus laryngis of taper modulating valve.
Thus, after the contacted scouring water of dust, be easy to sedimentation and be attached in eroded area groove 2, follow-up dust is only with recessed, and the grit friction of adhering in 2 has been avoided and cone Surface Contact that eroded area is outer, thus the working life that can greatly improve modulating valve.
