Embodiment 3

[0069] Sulfur recovery exhaust treatment process, including the steps of:

[0070] (1) The sulfur tail gas enters the incinerator, at 500 ° C, combustion treatment;

[0071] (2) Cooling treatment after the burning gas is taken until the gas temperature is 250 ° C;

[0072] (3) The treated gas enters the filler region via the super - gravity gas gas inlet, the concentration of 20-30 wt% sodium hydroxide solution is fluid passage, rotating the passage into the filler region, in the filler zone, gas fluid exchange;

[0073] (4) The liquid exchanged liquid is entered into the fluid inlet of the super - gravity oxidation machine. After the fluid passage, the rotary passage is spin into the filler region, the air enters the filler region, and the liquid oxidation is performed.

Abstract

The invention relates to a supergravity oxidation machine, a sulfur recovery tail gas treatment device and a process. The supergravity oxidation machine is characterized in that a hollow rotating shaft with a fluid channel is arranged on the central axis of a shell and penetrates through the shell, and a sleeve with a gas channel function sleeves the hollow rotating shaft; meanwhile, a rotating channel which is communicated with the packing area and is provided with a spiral channel is formed on the basis, self-spinning entering of fluid is achieved after the fluid passes through the hollow rotating shaft and then passes through the rotating channel, and the circumferential speed is increased under the rotating acting force, the shearing force and the self-spinning acting force of the fluid at the moment when the fluid enters the packing area; and the generated centrifugal force pushes the fluid to the outer edge, and the gas with oxidizing capacity is crushed, torn and mixed in the filler area, so that the gas-liquid contact sufficiency is improved, and a very good liquid oxidizing effect is obtained. In addition, the sulfur recovery tail gas treatment device and process can effectively reduce the sulfur content in the acid gas.

Description

Technical field [0001] The present invention relates to a sulfur recovery exhaust gas treatment apparatus and process belonging to the field of desulfurization technology. Background technique [0002] Acid gas is a common industrial emissions in industrial production, especially in refinery; sulfur tail gas is one of acidic gas, direct discharge can result in damage to the environment, according to the state's environmental governance, GB31570-2015 proposed The emission requirements need to be controlled by hydrogen sulfide and sulfur dioxide content at 50 mg / m. 3 Within. [0003] Currently, for H 2 Sikikikikikikiki is generally converted to sulfur recovery by Claus method. It is called a Claus sulfur recovery apparatus, including Claus furnace, Claus. Reactor, exhaust gas treatment and other devices. The process of sulfur recovery is 92-95%, even with three-stage, four-stage catalytic converters and high-activity catalysts, the total sulfur recovery rate can only reach 96%, s...
