Description

Acid water storage tank that high-order was taken out

Technical Field

The utility model relates to the technical field of acid water storage tanks, in particular to a high-position extraction acid water storage tank.

Background

The existing V-5104A/B tank has the defects that:

1. the skimming line is single in skimming and easy to block.

2. The tank draw was too low, about 30CM from the bottom of the tank.

3. The tank cleaning period is short.

4. The line of communication between tank A and tank B is too low for about 15cm from the bottom of the tank.

Cause of V-5104A/B can defect:

1. the hydrogenated acid water has serious oil and more impurity sediment, and the raw materials are easy to stir up the bottom of the tank to obtain sediment after entering the tank, so that the suction load of the pump is increased.

2. The sediment is deposited at the bottom of the tank above the pump outlet and tends to clog the pump inlet filter.

3. Because the communication line is too low, if only the tank B is cleaned, sediment of the tank A can enter the tank B through the communication line after the liquid level of the tank A is higher than the overflow liquid level, and the tank cleaning period is shortened.

In addition, the term "include" and any variations thereof are intended to cover a non-exclusive inclusion.

The present utility model will be described in further detail with reference to the accompanying drawings.

Example 1

The model of the acid water storage tank 7 is an acid water storage tank V5104A/B, and the main operation parameters are as follows: nominal volume 1000m ³ The design temperature is 110 ℃, the design pressure is 2940Pa, the design pressure is 294Pa, the main material Q235B of the tank body is the same, the flushing mass of the storage tank is 1199000Kg, and the tank body is 37880Kg.

The middle part of the top of the acid water storage tank 7 is provided with a tank wall manhole 5, the right side of the top of the acid water storage tank 7 is provided with a light hole 6, the left side of the top of the acid water storage tank 7 is provided with a flame arrester breather valve 4, and the top of the acid water storage tank 7 to the left is respectively provided with a nitrogen inlet 3, a remote transmission liquid level meter 2 and a steam pipe 1;

the outside of the acid water storage tank 7 is additionally provided with a high-level extraction line 8 with the height of 1.8 m.

Example 2

On the basis of the embodiment, a high-level extraction line 8 with the height of 1.5m is additionally arranged on the outer side of the acid water storage tank 7.

This novel increase high-order line (1.5-1.8 meters) of taking out can effectively avoid deposit such as A jar tank bottoms fatlute to get into the B jar, and the feeding is subsided the back through A jar and is got into the impurity that the B jar can reduce to get into the B jar, prolongs the clear jar cycle of B jar. The acid water from hydrogenation is much in oil, the skimming height is controlled to be about 9.6m, the V-5104A tank outlet is used for feeding the B tank through the V5104B tank outlet, the long-time multi-frequency skimming is convenient, and the skimming effect is very good.

The working principle of the novel: because the current hydrogenation acidic water quantity can not ensure the continuous operation of the acidic water stripping device, the acidic water can be effectively settled through high-position extraction.
