Problems solved by technology

[0003] In view of the above-mentioned deficiencies, there is currently a method for directly removing hydrogen sulfide gas from liquids. Because hydrogen sulfide is a colorless highly toxic gas with the smell of rotten eggs at normal temperature, it is also a nerve agent and is also an asphyxiating agent. And irritating gas, in the process of removing hydrogen sulfide gas, the sealing performance of the equipment to hydrogen sulfide gas should be ensured to be good, and the technicians should strictly abide by the operating rules during the operation, and a little carelessness may lead to poisoning , or even death, and after the hydrogen sulfide gas is removed from the liquid, the hydrogen sulfide gas needs to be processed to ensure that the hydrogen sulfide gas does not leak, so the safety performance of this method is poor, the equipment requirements are high, and the processing cost is high. Good for promotion

Embodiment 1

[0025] Such as figure 1 As shown, in this embodiment, the system for removing hydrogen sulfide gas in a liquid by using a hydrophobic membrane material includes a stock solution tank 1, a liquid supply pump I2 communicated with the stock solution tank 1, and a liquid supply pump I2 connected to the liquid supply tank 1. The degassing device 3 connected to the pump 12, the degassing device 3 is provided with a stock solution chamber 31 and an absorption liquid chamber 32, and a degassing film 33 is arranged between the stock solution chamber 31 and the absorption liquid chamber 32. In this embodiment, the degassing membrane 33 is a hydrophobic membrane material, the liquid supply pump 12 communicates with the raw liquid chamber 31, and the degassing device 3 is provided with a processing unit that communicates with the raw liquid chamber 31. The liquid output pipeline 4, the system that utilizes hydrophobic membrane material to remove hydrogen sulfide gas in the liquid also inc...

Embodiment 2

[0040] In this embodiment, the difference from Embodiment 1 is that the treatment liquid output pipeline 4 is not connected to the raw liquid tank 1, as long as the solution containing hydrogen sulfide gas passes through the degassing device 3 once, degassing can be achieved. In addition to standard conditions, at this time, the treatment liquid output pipeline 4 can directly utilize the treated liquid without recirculating treatment.

[0041] The invention is applied to the technical field of removing hydrogen sulfide gas in liquid.

Description

technical field [0001] The invention relates to a system and technology for removing hydrogen sulfide gas in liquid by using a hydrophobic membrane material. Background technique [0002] Hydrogen sulfide is the simplest of sulfur hydrides, also known as hydrogen sulfuric acid, and its molecular geometry is similar to that of water molecules, which is curved, so it is a polar molecule. At present, the hydrogen sulfide gas in the liquid is usually removed by precipitation method. The method used to remove the hydrogen sulfide gas is to add the reaction solution to the liquid containing hydrogen sulfide gas, so that the hydrogen sulfide gas reacts with the reaction solution and produces precipitation, and then the liquid For filtering, the process of this method is complicated and the steps are cumbersome. At present, there are also methods for removing hydrogen sulfide gas in liquids without using precipitation methods, such as the Chinese patent publication No. 102144019A, ...
