Description

Technical Field

[0001] The utility model relates to the technical field of scrubbing gas tanks, in particular to a hydrogen sulfide-resistant scrubbing gas tank. Background Art

[0002] In the process of preparing gasoline, diesel and wax oil fractions from crude oil, waste gas containing hydrogen sulfide gas will be generated. If it is directly discharged into the environment, it will cause great harm to human health and the environment. Hydrogen sulfide is an acute and highly toxic substance. Inhaling a small amount of high-concentration hydrogen sulfide can be fatal in a short time. Low concentrations of hydrogen sulfide have effects on the eyes, respiratory system and central nervous system. The gas scrubber is an instrument used to wash impurities in the gas. Its main purpose is to remove impurities in the gas through bubbling absorption (dissolution or chemical reaction) with a selected suitable liquid medium to achieve the effect of purifying the gas.

[0003] When existing hydrogen sulfide-resistant scrubbing gas tanks are scrubbing hydrogen sulfide gas, the air inlet pipe is usually inserted into the scrubbing tank so that the air inlet tank is located in the solution, wherein the exhaust pipe is higher than the solution. However, when the air inlet pipe is directly inserted into the solution, the discharged hydrogen sulfide gas cannot be evenly contacted with the solution, resulting in a decrease in the adsorption efficiency of the hydrogen sulfide gas. To this end, we propose an anti-hydrogen sulfide scrubbing gas tank to facilitate the uniform discharge of hydrogen sulfide gas into the solution, so that the hydrogen sulfide gas is evenly adsorbed and the adsorption efficiency is improved. Utility Model Content

[0006] By adopting the above technical solution, when washing the hydrogen sulfide gas mixture, after the solution adsorbing hydrogen sulfide is injected into the tank body through the water inlet valve pipe, since a dispersion mechanism is installed at the cover wall of the sealing cover, the dispersion mechanism is composed of an air inlet pipe, a connecting pipe, a cavity shell and a dispersion pipe. After the hydrogen sulfide gas enters the connecting pipe through the air inlet pipe, since the other end of the connecting pipe is connected and installed with a cavity shell, the cavity shell is located in the solution. Since the shell wall of the cavity shell is connected and installed with a dispersion pipe, the gas is evenly discharged through the dispersion pipe, so that the gas evenly enters the solution, so that the hydrogen sulfide gas and the solution are adsorbed and fused. Since the size of the cavity shell is smaller than the inner diameter of the tank body, the gas that is not adsorbed flows to the top of the solution, so that the gas containing hydrogen sulfide is evenly discharged into the solution through the dispersion pipe, so that the hydrogen sulfide gas is quickly adsorbed by the solution, thereby improving the washing efficiency of the hydrogen sulfide gas.

[0007] Specifically, it also includes a sealing mechanism, and the tank mouth of the tank body is equipped with a sealing mechanism.

The tank mouth of the tank body is threadedly connected with an external threaded tube, and a sealing cover is welded at the tube mouth of the external threaded tube. An openable exhaust valve tube is connected and installed on the cover wall of the sealing cover. A pressure detection gauge is installed on the cover wall of the sealing cover, and the external threaded tube passes through the sealing ring.

[0010] By adopting the above technical solution, when the tank mouth of the tank body is sealed, a sealing mechanism is installed at the tank mouth of the tank body, and the sealing mechanism is composed of a sealing cover, an exhaust valve tube, a pressure detection gauge, an external threaded tube and a sealing ring. Since the external threaded tube is welded at the bottom of the sealing cover, after the external threaded tube passes through the sealing ring, since a threaded groove is provided at the tank mouth of the tank body, the external threaded tube is threadedly connected to the threaded groove to achieve sealing of the tank mouth. Since the exhaust valve tube is connected and installed at the cover wall of the sealing cover, personnel open the exhaust valve tube to conveniently discharge the mixed gas after the adsorbed hydrogen sulfide, and detect the pressure in the tank body through the pressure detection gauge to avoid air leakage in the tank body.

[0011] Specifically, a thread groove connected to the external threaded pipe is provided at the tank mouth of the tank body.

[0012] By adopting the above technical solution, the external threaded pipe can be conveniently connected to the tank mouth of the tank body through the thread groove.

[0013] Specifically, a base is installed at the bottom of the tank body.

After the hydrogen sulfide gas enters the connecting pipe through the air inlet pipe, the other end of the connecting pipe is connected to the cavity shell. The cavity shell is located in the solution. Since a dispersion pipe is installed at the shell wall of the cavity shell, the gas is evenly discharged through the dispersion pipe, so that the gas evenly enters the solution, so that the hydrogen sulfide gas and the solution are adsorbed and fused. Since the size of the cavity shell is smaller than the inner diameter of the tank body, the gas that is not adsorbed flows to the top of the solution, so that the gas containing hydrogen sulfide is evenly discharged into the solution through the dispersion pipe, so that the hydrogen sulfide gas is quickly adsorbed by the solution, thereby improving the washing efficiency of the hydrogen sulfide gas.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

Since the shell wall of the cavity shell 703 is connected to and installed with a dispersion pipe 704, the gas is evenly discharged through the dispersion pipe 704, so that the gas evenly enters the solution, so that the hydrogen sulfide gas and the solution are adsorbed and fused. Since the size of the cavity shell 703 is smaller than the inner diameter of the tank body 1, the unadsorbed gas flows to the top of the solution, so that the gas containing hydrogen sulfide is evenly discharged into the solution through the dispersion pipe 704, so that the hydrogen sulfide gas is quickly adsorbed by the solution, thereby improving the washing efficiency of the hydrogen sulfide gas.

[0029] When in use, the mouth of the can body 1 can be sealed by the sealing cover 201 .

[0030] like Figure 1 and Figure 2 As shown, the sealing mechanism 2 is composed of a sealing cover 201, an exhaust valve tube 202, a pressure detection gauge 203, an external threaded tube 204 and a sealing ring 205. The tank mouth of the tank body 1 is threadedly connected with an external threaded tube 204, and the sealing cover 201 is welded at the tube mouth of the external threaded tube 204.
