The gas respectively enters the oxidation cavity 3 from the hydrogen sulfide gas inlet 1 and the air inlet 2, and sequentially passes through the inflow gas path 301 and the outflow gas path 302 to carry out oxidation treatment on the gas.
The oxidation cavity 3 comprises an inflow gas path 301 and an outflow gas path 302, the inflow gas path 301 is close to the hydrogen sulfide gas inlet 1, the outflow gas path 302 is close to the cyclone tower 4, and gas entering the oxidation cavity 3 firstly passes through the inflow gas path 301 and then enters the outflow gas path 302.
The oxidation tower is internally provided with active carbon 303 and a microwave radiation cavity 304 at intervals, a microwave source 3041 is arranged outside the microwave radiation cavity 304, the top of the oxidation cavity 3 is provided with a spray head 305, one end of the spray head 305 is connected with a water tank at the bottom of the cyclone tower 4, and the other end of the spray head 305 is arranged in the oxidation cavity 3. The gas reacts with oxygen under the action of microwave radiation and the catalysis of the active carbon 303, and is oxidized into elemental sulfur and water, and the reaction equation is as follows:
。
the activated carbon 303 can be oxidized by adsorption
The steam can desorb the elemental sulfur attached to the surface of the activated carbon 303. Specifically, under the action of microwaves, the temperature in the oxidation chamber 3 rises, and when the temperature in the oxidation chamber 3 is higher than 118 ℃, the elemental sulfur can volatilize into elemental sulfur in a liquid state or elemental sulfur in a gaseous state, and the elemental sulfur in the liquid state and the gaseous state can be discharged from the oxidation chamber 3 along with water vapor, and then enters the cyclone tower 4. The sulfur simple substance and the steam generated after oxidation can enter the cyclone tower 4 for recycling.
Wherein, the tower plate blades of the cyclone tower 4 are fixed windmill blades, the airflow generates rotation and centrifugal motion when passing through the blades, the absorption liquid is uniformly distributed to each blade through a middle blind plate to form a thin liquid layer, forms rotation and centrifugal effect with the upward rotating airflow, is sprayed into fine liquid drops and is thrown to the back of the tower wall. The droplets are gravity-fed to the sump and flow through the downcomer to the blind zone of the next tray. The air flow to be treated with certain wind pressure and wind speed enters from the bottom of the tower and exits from the upper part of the tower. The absorption liquid enters from the upper part of the tower and exits from the lower part of the tower. The air flow and the absorption liquid do relative motion in the tower, and a water film with a large surface area is formed at the structural part of the 4 plates of the cyclone tower, thereby greatly improving the absorption effect. The absorption liquid of each layer falls into a collecting tank at the edge under the action of rotational flow centrifugation, and then enters the next layer of tower plate through a flow guide pipe to perform the absorption action of the next layer.
The main mechanisms are inertial collision of dust particles and liquid drops, centrifugal separation, liquid film adhesion and the like. The tray has high opening rate, high capacity, low pressure drop and high operation flexibility. The gas-liquid contact time is short, and the method is suitable for the gas-phase diffusion control process, such as direct gas-liquid contact heat transfer, rapid reaction absorption and the like. Therefore, the desulfurizing agent used in the desulfurization process should be of a fast reaction absorption type, and is not suitable for a desulfurizing agent with a slow reaction speed, such as calcium carbonate.
A primary spraying device is designed at the inlet of the flue, and when flue gas passes through the inlet flue, mass transfer and heat exchange are carried out on the flue gas and water mist formed by spraying arranged at the inlet flue section, so that preliminary cooling and partial sulfur dioxide removal are obtained, and the flue gas tangentially enters the absorption tower. The flue gas is accelerated and swirled in the absorption tower through a swirl pneumatic device, and the smoke dust and the atomized absorption liquid are collided, attached, condensed, centrifugally separated and the like, so that the smoke dust is thrown to the tower wall and flows to the tower bottom along with a water film on the tower wall. The dust removal efficiency of the cyclone plate spray tower can reach more than 98.5 percent. Through the arrangement of the rotational flow pneumatic device, the rotation times of the smoke in the cylinder body at the same height are increased, the passing path is increased, the gas phase turbulence is violent, and the smoke and the absorption liquid are fully collided, contacted, dissolved and absorbed in time and space.
Specifically, the cyclone tower 4 is used for purifying the gas with the liquid elemental sulfur and the solid elemental sulfur to separate the gas and the elemental sulfur.
