Embodiment 1

[0017] A hydrogen sulfide absorption device, such as figure 1 As shown, including absorption tower, induced draft fan, and hydrogen sulfide detector, one section of the movable hose is connected to the trapping port, the other end is connected to the bottom of absorption tower A, the top outlet of absorption tower A is connected to the electromagnetic three-way valve, and the electromagnetic three-way The other two ports of the valve are respectively connected to the outlet pipeline at the bottom of the absorption tower B and the top of the absorption tower B, and the outlet pipeline at the top of the absorption tower B is also connected to the induced draft fan; among them, on the pipeline between the movable hose and the absorption tower A, The electromagnetic three-way valve and the outlet of the induced draft fan are equipped with hydrogen sulfide detectors.

[0018] A one-way valve is arranged on the pipeline between the movable hose and the absorption tower A. A one-way...

Embodiment 2

[0021] According to the conditions and steps described in Example 1, only the absorbent in the absorption tower is a liquid hydrogen sulfide reactant, which is sodium hydroxide solution.

Embodiment 3

[0023] According to the conditions and steps described in Example 1, only the absorbent in the absorption tower is a solid hydrogen sulfide reactant, which is a hydrogen sulfide scavenger.

[0024] Apparently, the present invention is equipped with multiple hydrogen sulfide detectors and two absorption towers to detect the concentration of hydrogen sulfide gas in real time, classify and judge and take corresponding measures. It has a high degree of automation, is safe and reliable, and has obvious technical advantages.

Abstract

The invention relates to a hydrogen sulfide absorbing device. The device is mainly used for collection and elimination of leaked hydrogen sulfide. The device comprises absorption towers, an induced draft fan and hydrogen sulfide testers. One end of a movable hose is connected with a gathering port, the other end of the movable hose is connected with the bottom of the absorption tower A, an outlet in the top of the absorption tower A is connected with an electromagnetic three-way valve, the other two ports of the electromagnetic three-way valve are connected with an outlet pipeline on the bottom of the absorption tower B and an outlet pipeline on the top of the absorption tower B respectively, and the outlet pipeline on the top of the absorption tower B is also connected with the induced draft fan. Due to the adoption of the technical scheme that the hydrogen sulfide testers are arranged on a pipeline between the movable hose and the absorption tower A, on the electromagnetic three-way valve and on an outlet of the induced draft fan, problems are solved. The device can be used for hydrogen sulfide absorption.

Description

technical field [0001] The invention relates to a hydrogen sulfide absorption device. Background technique [0002] In the process of natural gas purification and petroleum refining in my country's petrochemical industry, high concentrations of hydrogen sulfide are often associated. Poisoning accidents caused by leakage of hydrogen sulfide gas frequently occur in the petrochemical industry. Hydrogen sulfide is a highly toxic, colorless (transparent), heavier-than-air gas. Low concentrations of hydrogen sulfide have an odor similar to rotten eggs. When the content is high, the olfactory nerves are quickly paralyzed, and it is odorless and difficult to detect. Inhalation of a small amount of high-concentration hydrogen sulfide can be fatal in a short time. Once hydrogen sulfide leaks, it will seriously endanger the production safety of the device and the life safety of personnel, and will seriously pollute the nearby air and destroy the ecological environment.
