Embodiment Construction

[0019] A. The structure of the ammonia refiner:

[0020] As shown in Figure 1, the ammonia refiner body 2 is installed on the support 1, the liquid outlet 3 is connected to the lower side, and the ammonia gas inlet 4 containing hydrogen sulfide, the human body inlet and outlet 5 and the water inlet 6 are connected to the side. The top is connected with a gaseous ammonia outlet 7, a support plate 11 is installed in the lower middle of the inner cavity of the ammonia refiner, and a distributor 9 is installed on the upper part of the inner cavity of the ammonia refiner. The space between the support plate and the distributor constitutes a refining area. The reflux ammonia liquid inlet 8 installed on the upper part of the distributor passes through the wall of the ammonia refiner and is placed above the distributor, and communicates with the outlet pipe 3 through the return pipe 12 and the return pump 13 .

[0021] As shown in Figure 2: a liquid inlet 9.1 is provided on the upper ...

Abstract

The invention discloses a desulfurizing refining method and ammonia finisher, wherein the ammonia finisher comprises the following parts: support, liquid outlet, ammonium hydrosulfide gas inlet, human body inlet and outlet and water inlet and gas ammonia outlet, wherein the support board and distributor are set in the cavity of ammonia finisher, which forms ammonia refining area; the ammonia liquid reflux inlet is set on the top of distributor, which interconnects liquid outlet pipe through reflux pipe and reflux pump. The refining method of desulfurized ammonia comprises the following steps: 1. separating ammonia with hydrogen sulfide; 2. switching ammonia with hydrogen sulfide into ammonia finisher; 3. starting ammonia finisher; 4. operating the ammonia finisher.

Description

technical field [0001] The invention proposes a desulfurization and refining method for ammonia containing hydrogen sulfide in the sewage treatment process in the field of oil refining and chemical industry and an ammonia refining device thereof. Background technique [0002] Before the present invention was proposed, a large amount of waste water containing hydrogen sulfide and ammonia was produced in the refining and chemical production process. Since hydrogen sulfide and ammonia were contained in the waste water, the discharge standard could not be reached without treatment, especially the indicators of hydrogen sulfide and ammonia. Exceeded the standard. Usually, wastewater contains more than 1% ammonia, about 0.3% hydrogen sulfide, and oil and other impurities, so it must be treated to remove hydrogen sulfide, ammonia, oil and other impurities contained in wastewater. [0003] Ammonia and hydrogen sulfide crystallize into ammonium hydrogen sulfide solid at low temperat...
