Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
The embodiment of the utility model discloses a simple and rapid sulfur removal treatment agent detection device, which comprises a stirring unit 1, a reaction unit 2 and a recovery unit 3 as shown in figure 1. In order to obtain hydrogen sulfide gas of different uniform concentrations, hydrogen sulfide gas and other gases such as nitrogen gas, air, and the like may be introduced into the stirring unit 1. The stirring unit 1 comprises a gas stirrer, a gas inlet, a gas outlet and the like, and the other end of the gas inlet is connected with a hydrogen sulfide gas inlet pipeline 11. The two gas outlets are respectively connected with the gas inlet of the reaction unit 2 and the first hydrogen sulfide detector 4 through pipelines to obtain the initial concentration of hydrogen sulfide. When the hydrogen sulfide detector is used, after hydrogen sulfide gas and nitrogen gas are introduced into the stirring unit 1 according to a certain proportion, the gas in the stirrer can be uniformly mixed by starting the gas stirrer, so that the first hydrogen sulfide detector 4 in the next link can accurately verify the concentration of hydrogen sulfide.
The reaction unit 2 includes a closed reaction tank 21 in which a hydrogen sulfide treating agent is contained. The inlet 24 of the reaction tank 21 is at the bottom of the hydrogen sulfide treating agent to ensure complete immersion of the hydrogen sulfide gas in the sulfur removal agent, thereby improving the efficiency of the sulfur removal reaction. The reaction tank 21 also has two air outlets, one of which is connected to the air inlet of the recovery unit 3 and the other of which is connected to the second hydrogen sulfide detector 5. By measuring the hydrogen sulfide concentration and comparing it to the initial hydrogen sulfide concentration, the effectiveness of the sulfur removal agent can be evaluated. Notably, the reaction tank 21 is placed in an electric constant temperature water bath 22, and a magnet 23 is placed in the reaction tank 21. When the electric heating constant temperature water bath 22 is started, the magneton 23 in the reaction tank 21 starts to rotate, and the sulfur removing agent in the reaction tank 21 is uniformly stirred, so that the failure of the sulfur removing agent at the air inlet due to continuous treatment of the hydrogen sulfide gas can be avoided, and the bad sulfur removing effect is caused. The device can also change the temperature of the reaction tank 21 by adjusting the temperature of the electric heating constant temperature water bath 22 so as to provide different temperature conditions. When it is necessary to change the pressure in the reaction, an appropriate amount of nitrogen gas may be introduced into the stirring unit 1, and a pressure gauge may be provided in the stirring unit 1 for detection. This allows flexible control and regulation of the reaction conditions. In practice, the hydrogen sulfide gas is introduced into the reaction unit 2 to react with the sulfur removal agent after being treated by the stirring unit 1, and then the effect after the reaction of the sulfur removal agent is detected by the second hydrogen sulfide detector 5. Because only two units are used in the whole treatment process, the device has simple structure and easy realization, and the complex operation steps in the treatment process are effectively reduced.
Further, in order to prevent the untreated hydrogen sulfide gas from being discharged into the environment. The apparatus further comprises a recovery unit 3, as shown in fig. 2, the gas outlet 24 of the reaction tank 21 is connected to the gas inlet of the recovery unit 3 via a pipe. The recovery unit 3 comprises at least two recovery bottles in series, in which an alkaline liquid, such as 10% sodium hydroxide solution, is contained for absorbing unreacted hydrogen sulfide gas.
The stirring unit 1 further comprises a miscellaneous gas inlet line 12 which merges with the hydrogen sulphide inlet line 11 at the main line and is connected to the inlet of the stirring unit 1. Valves are provided on the hydrogen sulfide intake line 11 and the impurity gas intake line 12 to control the flow rate and the ratio of the different gases. Thus, the concentration and the proportion of different gases can be accurately controlled in the process of treating the hydrogen sulfide gas so as to meet different treatment requirements.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
