Description

A kind of adjustable aditus laryngis circumferential weld Venturi tube

Technical field

The utility model relates to a kind of adjustable aditus laryngis circumferential weld Venturi tube, belongs to technical field of metallurgical equipment.

Background technology

The upstriker circumferential weld Venturi tube that the utility model relates to is downstriker circumferential weld Venturi tube according to foreign data and domestic the introduction by Japan, German LURGI and three country variants of VAI in recent years.So-called upstriker and downstriker circumferential weld Venturi tube are meant that the cleaning system gas of breathing one's last for the flow direction of aditus laryngis, does not have unified title abroad, purify Europe to breathing one's last and are called ' RSW ' washer, China is translated into the circumferential weld Venturi tube.

With Japanese European-allies end of the century, offer the adjustable aditus laryngis circumferential weld of the 50t converter downstriker Venturi tube of Chinese Ma Gang company, claim the RSW technology again.Downstriker as shown in Figure 1 is adjustable aditus laryngis circumferential weld Venturi tube, its structure comprise collapsible tube, aditus laryngis, anemostat, heavy thallium, heavy thallium lifting executing agency, sealing device fixing port, ring pipe supply water spraying, 90 degree bend pipe dehydrators, foldingly pull reverse 90 degree and heavily manage dehydrator, guiding trestle, guide post.1), because executing agency is in the collapsible tube center problem of downstriker is adjustable aditus laryngis circumferential weld Venturi tube is:, air-flow is disturbed at 180 degree winding pipe exit places, and air inlet flings heavy thallium lifter drawing bar; 2), because executing agency is in the collapsible tube center, although use annular spray pipe, water distribution is still uneven, pressing close to the lifter drawing bar place can not have water, and is difficult to make water atomization good, pull bar is corroded has certain influence service life in addition; 3), require the anemostat angle not bring to design and produce trouble with heavily the thallium angle is identical;

Adjust aditus laryngis section executing agency in the above or below, the counterweight thallium all is the pressure that bears system airflow;

Except that a cover being arranged to the Venturi tube water system, must establish a cover water flushing locking system in addition.

P-A in addition, " " Venturi tube changes into through Japanese firm " R-D " oval turnover panel Venturi tube still has following problem:

A), the turnover panel of oval adjustable aditus laryngis section, no matter change any one angle, then air-flow must be disturbed, two sidewind inequalities;

B), the easy dust stratification of aditus laryngis, be difficult for to rotate, even stuck, section can't be adjusted;

C), power consumption is big, must have nitrogen to disclose pin power, increased nitrogen supply (NS) and system complexity;

D), the high water spray of water quality requirement eyelet little (φ 5-φ 7mm), quantity be many, the eyelet that guarantee to spray water is stifled has any problem.Eyelet does not have water if be blocked, and will influence dust removing effects, so gas cleaning effect instability;

E), the both sides hole for water spraying half in enlarging, half is in reducing, the reducing gas cleaning is effective, enlarging is unfavorable to gas cleaning, " P-A " Venturi tube do not have this defective.

From above-mentioned situation, there is problem in various degree in foreign products.

Summary of the invention

The purpose of this utility model is to provide a kind of adjustable aditus laryngis circumferential weld Venturi tube, and this Wen's guard system is simple, and power consumption is few, and maintenance workload is few.

For achieving the above object, the technical solution of the utility model is: the executing agency of this upstriker is adjustable aditus laryngis circumferential weld Venturi tube comprises water feed apparatus, collapsible tube, aditus laryngis, anemostat, adjusting aditus laryngis section.And be aided with sealing device, executing agency's guider, special-purpose manhole.

The characteristics of this Venturi tube: have only a water inlet pipe to supply water, needn't join a cover nozzle again and connect trivial water system to a nozzle.

The diffusion tube lengths of this Venturi tube is that gas cleaning is effective about the twice of the adjustable aditus laryngis circumferential weld of downstriker Venturi tube diffusion tube lengths, and the gas cleaning dustiness is all at≤50mg/m3.

It is tapered that the anemostat of this Venturi tube is positioned at top, below is aditus laryngis, collapsible tube, under be a heavy thallium, in the upper end of heavy thallium is the heavy thallium elevating mechanism of a rod-type, the top of bar is sealing device, is guide post, guiding trestle in heavy thallium lower end, knows being provided with water injector under guide post.Be provided with active support on anemostat, a side is provided with special manhole below active support, and another manhole is positioned at the below of nozzle.Air-flow is from bottom to top regulated the heavy thallium of aditus laryngis section, directly bears the buoyancy from system.

The beneficial effects of the utility model: this is adjustable, and aditus laryngis circumferential weld Venturi tube does not have nitrogen to disclose needle system, there are not nitrogen supply (NS), power consumption, this Venturi tube has only a major diameter spraynozzle, it is few that water injection nozzle stops up chance, this Wen's guard system is simple, easy to manufacture, Maintenance and Repair are few, have certain economic benefits.

Below in conjunction with drawings and Examples to the present invention's detailed explanation of making comparisons.

Description of drawings

Fig. 1 is the adjustable aditus laryngis circumferential weld of the 50t converter downstriker venturi tube structure schematic diagram of prior art;

Fig. 2 is the adjustable aditus laryngis circumferential weld of a upstriker of the present utility model venturi tube structure schematic diagram.

The specific embodiment

With reference to Fig. 2, this is the adjustable aditus laryngis circumferential weld of a upstriker of the present utility model venturi tube structure schematic diagram.

As shown in the figure, it is tapered that the anemostat 1 of this Venturi tube is positioned at top, below be aditus laryngis 2, collapsible tube 3, under be a heavy thallium 4, be that a rod-type connects heavy thallium elevating mechanism 5 in the upper end of heavy thallium 4, the bottom of bar is a sealing device fixing port 6, connect guide post 9 in heavy thallium 4 lower ends, 9 displacements of control guide post are furnished with guiding trestle 8, are provided with active support 10 on anemostat 1, a side is provided with special manhole 11 below active support 10, and another manhole 12 is positioned at a side of nozzle.

The characteristics of this Venturi tube: have only a water inlet pipe to supply water, needn't join a cover nozzle again and connect trivial flushing water system to a nozzle.Air-flow is from bottom to top regulated the heavy thallium of aditus laryngis section, directly bears the buoyancy from system.

The diffusion tube lengths of this Venturi tube is that gas cleaning is effective about the twice of the adjustable aditus laryngis circumferential weld of downstriker Venturi tube diffusion tube lengths, and the gas cleaning dustiness is all at≤50mg/m3.Because the diffusion pipe range, the descending slow Yan of gas speed arrives system's normal speed again, and gas, liquid fine particle bump mix, and the coacervation time is long.

This Venturi tube does not have nitrogen to disclose needle system, does not have nitrogen supply (NS) and power consumption.Generally have only a major diameter nozzle, it is few that water injection nozzle stops up chance, requires not strict relatively to water quality.

Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, to the variation of above-described embodiment, the protection domain that distortion all will fall into the utility model claim.
