Description

Separation control device for contaminated brine {DEVICE FOR CONTROLLING AND SEPERATING POLLUTED SALT WATER}

The present invention relates to an apparatus for controlling the separation of contaminated brine.

For example, automotive materials are evaluated for quality through appropriate corrosion tests according to the location and conditions of use.

One of the quality evaluation methods is a method of conducting a corrosion test of a material through continuous salt spray using a salt spray tester under a certain condition for a certain period of time.

In addition, the salt spray device is installed upright with a number of test materials at regular intervals, and the corrosion state of the surface of the material is checked by continuous salt spraying through a nozzle at a predetermined time and temperature.

In other words, the salt water sprayed through the nozzle flows along the airflow inside the experimental apparatus and comes into contact with the surface of the material, accelerating the corrosion of the material.

Corrosive substances or foreign substances generated on the surface of the material grow over time and fall to the lower part of the material surface and accumulate under the material, affecting the material surface. Is maximized.

Accumulation of contaminants such as corrosive substances inside the test apparatus adversely affects the quality of the corrosion test material. In addition, the corrosion test was not conducted efficiently due to the deterioration of the performance of the test apparatus, and it was difficult to derive reliable test data.

In particular, the amount of salt water sprayed per hour irrespective of the quantity of material for one test is supplied through the nozzle at a constant rate, and the amount of salt water used and the cost of wastewater treatment have continuously increased due to the mixed wastewater treatment of contaminated saltwater and non-contact saltwater in contact with the material surface. .

After the experiment was completed, the material was removed and the test apparatus was internally disassembled and cleaned to maintain cleanliness, but this took a lot of time and manpower.

In addition, in the cleaning process through the separation of contaminated salt water and non-contact salt water in contact with the material surface, damage to the experimental device frequently occurs, which increases downtime and maintenance costs due to performance maintenance problems.

The present invention separates contaminated salt water in contact with the material surface and corrosive substances generated from contact with salt water from salt water sprayed on the material surface during a corrosion experiment using a salt spray device, and non-contaminated salt water not in contact with the material surface. Provides a control device for separating contaminated brine so that it can be controlled.

The hopper may be formed in an inverted triangular shape having an open top and an inner space for storing chlorine.

At least one pair of supports are installed side by side at regular intervals inside the chamber, and support plates for supporting the hopper by seating and supporting the hopper may be installed at both ends of the hopper.

The assembly may have a flow space through which the upper and lower portions can pass through and allow the salt water sprayed on the surface of the test material to flow from the upper to the lower portion.

The assembly is formed in a rectangular body shape having a pair of long side portions and a pair of short side portions facing each other, and a plurality of mounting grooves may be disposed along the length direction of the long side portion on the upper surface of the pair of long side portions.

The upright angle of the test material can be controlled by adjusting the width and height of the mounting groove.

A filter disposed below the assembly may be installed inside the hopper.

The hopper may have a space that is spaced apart from the inside of the chamber or an adjacent hopper of the hopper.

A drain line for discharging contaminated brine stored in the hopper may be installed under one surface of the hopper.

In particular, contamination of the surface of the test material 20 is accelerated by a corrosion experiment conducted through continuous spraying for a long time, and increased corrosive substances and deposits are filtered on the upper portion of the internal filter 230 of the assembly 200.

In addition, the non-contaminated salt water that is not in contact with the surface of the test material among the salt water sprayed during the experiment is the space part 13 of the experimental device, that is, the space between the hopper 100 and the hopper 100, and the hopper 100 and the chamber. (10) It falls downward through the space between the inner surfaces and is stored in the inner floor of the chamber 10.

In this way, the non-contaminated brine that is not in contact with the material surface is separated from the contaminated brine in contact with the material surface, and is discharged from the inside of the chamber 10 to be recycled.

After the experiment is completed, the experiment material 20 mounted upright in the mounting groove 210 of the assembly 200 is removed through the opening of the chamber 10 of the experiment device,

The assembly 200, the filter 230, and the support 240 are removed from the hopper 100 and separated, and contaminated corrosive substances and deposits remaining on the filter 230 are removed.
