Abstract

The utility model provides an external-spraying type anti-abrasion venturi dust removal device which effectively improves dust removal efficiency and prolongs service life. The external-spraying type anti-abrasion venturi dust removal device comprises a body which is composed of a reducing pipe, a venturi throat, an increasing coupling and a dewaterer through connection in sequence. An overflow device is arranged on the upper portion of the reducing pipe, and used for eliminating a dry and wet interface and horizontal displacement and longitudinal displacement caused by temperature. A 3-5mm water membrane layer is formed on the inner wall of the overflow device so as to flush away mine dust cemented on the inner wall of the dust removal device. A water supply pipe is arranged at the connection joint of the venturi throat and the increasing coupling, and the reducing pipe is provided with a water spray nozzle which is connected with the water supply pipe through a high-pressure glue pipe. The external-spraying type anti-abrasion venturi dust removal device can form even water spray cones at a throat port, is high in dust removal efficiency, and small in venturi throat resistance and power consumption, and greatly reduces air resistance at the throat port through adoption of the annular side water spray nozzle for water supply, solves the problems that a traditional venturi dust removal device is frequent in water spray nozzle blocking and mine bonding under the condition of using factory network circulating water, and is obvious in dust removal effect in practical use.

Description

External spraying type abrasionproof shaped Venturi dedusting device
Technical field
The utility model belongs to metallurgical equipment, particularly a kind of shaped Venturi dedusting device for lead, the cold cylinder of zinc smelting industry and back powder preparation.
Background technology
At plumbous, zinc smelting industry, be an important step in the technological operation in cooling drums and the back powder preparation.Produce the flue gas that a large amount of high temperature are moist, contain a large amount of sticky dust particles in the production process, it is large that the conventional venturi tube deduster can the too high SR that causes of gas speed in actual motion, causes the efficiency of dust collection fluctuation large, and the blower fan bonding is serious, and fault rate is high; Employed bowl-type nozzle must be arranged on aditus laryngis air-flow high velocity, flow resistance greatly and be easy to the mine dust that bonds, particularly aditus laryngis and the overflow device bonding is serious, body is rinsed erosion and is needed very soon often to change.At present, the trunnion body adopts phosphor bronze to make mostly, and manufacturing cost is large, the manufacturing cycle is long, and is very fast because rinsing erosion owing to the higher dust concentration plateau of adding of cigarette temperature, change very difficult, so operating cost is very high.
The utility model content
The purpose of this utility model is for the deficiency on the shaped Venturi dedusting device technique that adopts in present lead, the cold cylinder of zinc smelting industry and the back powder preparation, and the external spraying type abrasionproof shaped Venturi dedusting device in a kind of Effective Raise efficiency of dust collection and service life is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of external spraying type abrasionproof shaped Venturi dedusting device, comprise body, described body is connected in sequence by reducing pipe, Venturi throat, increaser and dehydrator, described reducing pipe top is provided with overflow device, described overflow device be used for to eliminate do that wet interface and Yin Wendu cause laterally, length travel, and form the water film of about 3~5mm at inwall, wash away the mine dust that is bonded in the deduster inwall; The junction of described Venturi throat and increaser is provided with feed pipe, and described reducing pipe is provided with water spout, and described water spout is connected with feed pipe by high-pressure rubber pipe.
Described water spout is that external spraying type is circular layout, and nozzle is stainless steel, adopts the taper damascene structures, and plug and cone are detachable.
Described water spout 7 is 23 ° with the angle of horizontal plane.
The interior wall liner of described body posts anti-wear material.
Feed pipe is annular feed pipe.
Described overflow device integral body is for flow structure and be provided with sewage draining exit.
Described reducing pipe and the embedding of overflow device phase.
External spraying type abrasionproof shaped Venturi dedusting device of the present utility model can form uniform water smoke cone at aditus laryngis, efficiency of dust collection is high, trunnion resistance, power consumption are little, and adopted annular lateral spray type water nozzle to supply water, greatly reduce the aditus laryngis vapour lock, solved traditional venturi scrubber in water nozzle frequent jams and the sticking ore deposit problem used in factory's net recirculated water situation, dust removing effects is obvious in practice is used.The utility model prepares the deficiency that dust arrester exists for traditional cooling drums and back powder, and transformation facts have proved and improved to a great extent systematic air flow efficient and comparable running rate, has reduced repair density, reduces spillage of material.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A position among Fig. 1;
Fig. 3 is the partial enlarged drawing at B position among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model external spraying type abrasionproof shaped Venturi dedusting device comprises body as shown in Figure 1, body is connected in sequence by reducing pipe 2, Venturi throat 3, increaser 4 and dehydrator 5, reducing pipe 2 tops are provided with overflow device 1, overflow device 1 be used for eliminating do that wet interface and Yin Wendu cause laterally, length travel, and form the water film of about 3~5mm at inwall, wash away the mine dust that is bonded in the deduster inwall; The junction of described Venturi throat 3 and increaser 4 is provided with feed pipe 6, and described reducing pipe 2 is provided with water spout 7, and described water spout 7 is connected with feed pipe 6 by high-pressure rubber pipe.
The Venturi throat flow velocity is by 76 m/s design, and the too high meeting of flow velocity causes resistance sharply to raise, and flow velocity is crossed the low efficiency of dust collection that can cause and descended, and causes blower fan accident rate height, discharging to exceed standard.
Water spout 7 is for external spraying type is circular layout, and nozzle is stainless steel, adopts the taper damascene structures, and plug and cone are detachable.Can dismantle easily, change, easy access, cleaning.Described water spout 7 is 23 ° with the angle of horizontal plane.
As shown in Figure 2, the interior wall liner of body posts anti-wear material 8.
Feed pipe 6 is annular feed pipe.
Overflow device 1 integral body is for flow structure and be provided with sewage draining exit.Reducing pipe 2 and overflow device 1 phase embedding improve flue gas gas speed; Increaser 4 reduces the flue gas static pressure and water droplet is separated.
Practice operation proves that system water supply can adopt factory's net recirculated water, and hydraulic pressure is with 2~2.7 kilograms per centimeter 2Be advisable 25~30 tons/hour of overflow device outputs, 40~50 tons/hour of water nozzle outputs.This device smoke treatment energy consumption is low, stable, and long service life has solved the obstruction under factory's net recirculated water condition, sticking ore deposit problem, and efficiency of dust collection is high.
