Description
Technical Field
The utility model relates to a modified converter wet process primary dust collector.
Background
The wet-process dust removal of the 40t converter adopts an OG wet-process dust removal mode, and the process flow is as follows: converter hood → evaporation cooling flue → water-cooling fire extinguishing water seal → spray evaporation washing tower → interconnecting pipe → circular seam venturi → dehydration tower → gas pipeline → primary dust removing fan → three-way valve → ignition and diffusion (or recovery through gas analyzer and water seal check valve into gas cabinet). Only the spray evaporation washing tower and the dehydration tower in the plant have the dehydration function. Since the dehydrator is in the form of a hollow cylinder having a large diameter, dehydration efficiency for liquid droplets is poor. The smoke dust contains a large amount of water vapor, and the water-containing smoke gas enters the primary dust removal fan and the pipeline, so that the operation life of the fan is influenced, the vibration of the fan is large, the water accumulation in the fan shell and the transmittance of the analyzer are low, and the service life of the fan and the transmittance of the gas analyzer are influenced.
Disclosure of Invention
An object of the utility model is to provide a dust collector is once carried out to modified converter wet process can increase the dehydration volume, reduces the water content in the smoke and dust for the gas analysis appearance transmissivity increases.
The technical scheme for realizing the purpose is as follows: the utility model provides a dust collector is once gone up to modified converter wet process, is including installing the horizontal pipe on the dehydration tower, and dehydration tower bottom sets up water seal device, horizontal pipe bottom in set up the convex breakwater of a radius 600mm, height 300mm, the horizontal pipe bottom of 350mm department is connecting the drain pipe of a 200mm internal diameter before the breakwater, water piping connection water seal device.
The newly added primary dust removal and dehydration device can be increased by 15m3The dehydration amount per hour is reduced, the water content in the smoke dust is reduced, the transmittance of the gas analyzer is increased by 5 percent, the water accumulation in the air pipe is obviously reduced, and better benefit is generated. The process device is simple, the investment is small, the cost is low, the low failure frequency of the permeability of the gas analyzer is reduced, the number of gas recovery furnaces is increased, the service life of the primary dust removal fan is prolonged, and the converter smelting is facilitated.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the connection structure of the present invention.
Detailed Description
An improved converter wet primary dust removal device is shown in figure 1 and comprises a horizontal pipe 2 which is arranged on a dehydration tower 5 and is provided with an inspection manhole 1, wherein a water sealing device 4 is arranged at the bottom of the dehydration tower, a circular arc-shaped water baffle 6 with the radius of 600mm and the height of 300mm is arranged in the bottom of the horizontal pipe 2, a drain pipe 3 with the inner diameter of 200mm is connected to the bottom of the horizontal pipe at the position of 350mm in front of the water baffle 6, and the drain pipe 3 is connected with the water sealing device 4.
