Abstract
Description
Technical Field
[0001] The utility model relates to an emergency treatment device, in particular to an emergency treatment device for ensuring the safe operation of a hydrogen peroxide storage tank. Background Art
[0002] Hydrogen peroxide (molecular formula H2O2) aqueous solution is commonly known as hydrogen peroxide. It is a colorless and transparent liquid and belongs to an oxidizing liquid. Common products in industrial production have concentrations of 27.5%, 35%, 50%, 60%, and 70%. Hydrogen peroxide is an explosive strong oxidant. It is non-flammable itself, but it will quickly decompose and cause explosion after contact with many inorganic compounds or impurities, while releasing a large amount of heat, oxygen and water vapor. Studies have shown that the oxidizing property of hydrogen peroxide increases with the increase of concentration, the reaction activity increases, and the energy density increases. When hydrogen peroxide with a concentration higher than 44wt% is mixed with organic matter, a condensed phase explosion may occur. Most heavy metals (such as iron, copper, silver, lead, mercury, zinc, cobalt, nickel, chromium, manganese, etc.) and their oxides and salts are active catalysts for the decomposition of hydrogen peroxide. Dust, cigarette ash, carbon powder, rust, etc. can also accelerate its decomposition. It can form explosive mixtures with many organic substances such as sugar, starch, alcohol petroleum products, etc., and can explode under impact, heat or electric sparks. There is a risk of explosion when heating in a confined space. It is very easy to decompose in alkaline solutions and can also decompose when exposed to strong light, especially short-wave radiation. The decomposition reaction rate of hydrogen peroxide increases with the increase of temperature, pH and impurity content. The heat released by decomposition further increases the temperature of the system and accelerates the decomposition rate. Neutral hydrogen peroxide solution with a pH value of 3.5-4.5 is the most stable.
[0003] At present, the emergency treatment method for hydrogen peroxide storage tanks of various concentrations in hydrogen peroxide production and use units is generally to stop feeding and discharging materials when over-temperature occurs, pass pure water into the storage tank through the batching pipeline, and spray water outside the tank to cool it down. The existing emergency treatment system lacks measures to quickly and evenly distribute pure water, prevent hydrogen peroxide from continuing to decompose, and provide sound and light warnings to people around the device.
[0004] CN117643848A discloses an emergency material removal system for an oxidation tower, which is a safety system for a hydrogen peroxide production device. However, the existing structure lacks a safety system for the hydrogen peroxide storage tank of the production device and the hydrogen peroxide storage tank of the hydrogen peroxide user.

[0018] A vent 3 with a flame arrester is installed on the hydrogen peroxide storage tank 1 on one side of the pressure relief manhole 2. Pressure relief is carried out through the vent 3 with the flame arrester. If the pressure relief is not timely, the pressure can be automatically relieved through the pressure relief manhole 2.
[0019] A stabilizer adding funnel 14 is installed at the top of the stabilizer tank 13 to facilitate adding stabilizer to the stabilizer tank 13 .
[0020] The outer side of the tank external spray water cut-off valve 8 is connected to the tank external spray water for easy control.

[0023] Working principle: When the utility model is used, under normal circumstances, when the pressure of the hydrogen peroxide storage tank 1 increases due to feeding or temperature rise, the pressure can be released through the vent 3 with a flame arrester. If the pressure is not released in time, it can be automatically released through the pressure relief manhole 2.
[0024] The hydrogen peroxide storage tank 1 is provided with a first remote thermometer 9, a second remote thermometer 10, a third remote thermometer 11 and a remote pressure gauge 12 for monitoring and setting an alarm value.
