Description
Technical Field
The utility model relates to the technical field of metallurgy, in particular to a wet dust removal system for a steel plant.
Background
The wet dedusting system for steel plant is characterized in that converter flue gas enters the dedusting system through a flue, and generally comprises a washing tower, a Venturi tube, a dehydrator and a fan, wherein an atomizing water nozzle and a heavy hammer are arranged in the system to control the flow of the flue gas so as to achieve the aim of dedusting; inside the flue gas that the converter produced inhales dust pelletizing system through the negative pressure that the fan produced, there are a large amount of gases and mud etc. to take the fan entrance at flue gas flow direction, can cause debris or water etc. to adhere to on high-speed moving impeller like this, thereby make fan load increase electric current rise, can cause motor overload to shut down when serious, must shut down the stove and overhaul, seriously influence the production progress, consequently, the fan that the dirt adhesion of dust pelletizing system caused in the industry needs to be solved and shuts down the problem urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a wet dust removal system for a steel plant, which can treat dirt before the dirt of the dust removal system reaches a fan, avoid shutdown and blowing out for cleaning the dirt and improve the production efficiency.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a wet dedusting system for steel plants comprises a converter, a flue gas collector, an atomizing water nozzle, a water discharge seal, a venturi tube, a heavy hammer, a dehydrator, a washing tower and a cleaning device; the flue gas collector is positioned right above the converter; a smoke collector is connected above the washing tower, a water drainage seal is arranged right below the washing tower, and a venturi tube is connected at the right lower part of the washing tower; a heavy hammer is arranged in the venturi; the right lower part of the venturi tube is connected with a dehydrator; the right side of the dehydrator is connected with a sewage disposal device; the atomization water nozzles are respectively arranged on the side surfaces of the washing tower and the venturi; the sewage disposal device comprises a water spray nozzle, a slurry pump, a sewage collection tank, a fan and a sewage discharge pipeline; the water spray nozzle is arranged on the upper pipe wall of the sewage discharge pipeline on the left side of the fan; the sewage collecting tank is arranged right below the sewage discharge pipeline; the slurry pump is arranged under the sewage discharge groove.
In the wet dedusting system for the steel plant, the number of the water nozzles is 1-3.
In the wet dedusting system for the steel plant, the water spraying direction of the water spraying nozzle is set to face towards the lower right, and the water spraying direction and the horizontal plane form an included angle of 30-40 degrees.
Advantageous effects
The utility model has the following advantages:
the wet dust removal system for the steel plant is provided with the dirt cleaning device, the water spray nozzle, the slurry pump and the dirt collecting groove are arranged at the inlet of the fan, and dirt is discharged when water or sludge enters the inlet of the fan along with airflow, so that sundries, water and the like are not attached to the impeller which rotates at a high speed, the fan operates normally, the motor is not overloaded to stop, the shutdown and shutdown maintenance are reduced, and the production efficiency is improved.

FIG. 2 is an enlarged cross-sectional view of the purge unit;
in the drawings, the reference numerals denote: 1. the device comprises a converter, 2, a flue gas collector, 3, an atomization water nozzle, 4, a water drainage seal, 5, a venturi tube, 6, a heavy hammer, 7, a dehydrator, 8, a water spray nozzle, 9, a slurry pump, 10, a sewage collection tank, 11, a fan, 12, a sewage discharge pipeline, 13 and a washing tower.
Detailed Description
The utility model is further explained below with reference to the figures and examples;
the wet dedusting system of the steel plant comprises a converter 1, a flue gas collector 2, an atomizing water nozzle 3, a water drainage seal 4, a venturi tube 5, a heavy hammer 6, a dehydrator 7, a washing tower 13 and a sewage disposal device; the sewage disposal device comprises a water spray nozzle 8, a slurry pump 9, a sewage collection tank 10, a fan 11 and a sewage discharge pipeline 12; the flue gas collector, the venturi tube, the dehydrator, the washing tower and the fan are connected together through pipelines; a large amount of flue gas generated by the converter is collected by a flue gas collector, enters a washing tower through a pipeline, and is subjected to preliminary dust fall through atomized water sprayed by an atomized water nozzle; then enters a dehydrator through a venturi tube for dehydration treatment.
According to the wet dust removal system for the steel plant, the bottoms of the washing tower and the dehydrator are respectively provided with a water drainage seal.
The wet dust removal system for the steel plant is provided with the dirt cleaning device, high-pressure water with pressure is sprayed out of a water spray nozzle of the dirt cleaning device, dirt in a pipeline is cleaned by the high-pressure water, the dirt enters the dirt collecting groove along with water flow and is discharged out of the pipeline by the slurry pump, and therefore the dirt cleaning device is only required to be started to pump away the dirt when the fan is at a low speed.
