Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to pollution-proof and environment-friendly sulfiding gas processing equipment. Background Art

[0002] Sulfurization fume usually refers to the mixed gas released during the production process of rubber and other sulfur-containing polymer products, especially in the high-temperature vulcanization process. These gases contain multiple components, such as sulfur dioxide, hydrogen sulfide and other organic sulfides, and may also include various volatile organic compounds such as xylene, n-heptane, methylhexane, etc. The emission of these gases needs to be effectively controlled to reduce the adverse effects on the environment and the health of workers.

[0003] In the prior art, sulfide gas is usually neutralized and desulfurized through a sulfide tower, and a wet sulfide tower is a type of sulfide tower. Large wet sulfide towers usually have multiple groups of spray layers staggered to ensure the contact area between the sulfide gas and the neutralizing liquid. Each additional spray layer means that more nozzles, pipelines, support structures, and related circulation pumps and control systems are required, which will directly lead to an increase in equipment costs and installation costs. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-pollution and environmentally friendly sulfide gas treatment equipment, which has the advantage of ensuring the contact area between the sulfide gas and the neutralizing liquid by setting fewer spray layers, and solves the problem of needing to stagger multiple groups of spray layers to ensure the contact area between the sulfide gas and the neutralizing liquid, and the high equipment cost and installation cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-pollution and environmentally friendly sulfide gas treatment equipment, comprising a main body mechanism, the main body mechanism comprising a liquid outlet cavity and a liquid infusion tube, a processing cavity is fixedly installed on the top of the liquid outlet cavity, one end of the liquid infusion tube is arranged at the bottom of the liquid outlet cavity, a spray mechanism is fixedly installed inside the processing cavity, a demisting mechanism is arranged on the top of the spray mechanism, the spray mechanism comprises a first spray rack, a three-way rotary joint is rotatably connected to the top of the first spray rack, a second spray rack is rotatably connected to the top of the three-way rotary joint, the three-way rotary joint is fixedly connected to one side of the liquid infusion tube, a plurality of atomizing nozzles are fixedly installed on the bottom of the first spray rack and the three-way rotary joint, a second driven gear is fixedly installed on the top of the first spray rack, a first driven gear is fixedly installed on the bottom of the second spray rack, and a driving gear is meshed and connected to one side of the first driven gear and the second driven gear.

[0006] As a preferred anti-pollution and environmentally friendly sulfide gas treatment equipment of the utility model, the atomizing nozzles of the outer rings of the first spray rack and the second spray rack are both rotated 30° toward the axis of the three-way rotary joint.

[0007] As a preferred anti-pollution and environmentally friendly sulfide gas treatment equipment of the utility model, the demisting mechanism includes a mounting frame, a plurality of corrugated plates are fixedly mounted inside the mounting frame, and demisting nets are fixedly mounted on both upper and lower sides of the mounting frame.

[0008] As a preferred anti-pollution and environmentally friendly sulfiding gas treatment equipment of the utility model, an air inlet is fixedly installed at the bottom of the treatment chamber, and an exhaust hole is fixedly installed at the top of the treatment chamber.

[0009] As a preferred anti-pollution and environmentally friendly sulfiding gas treatment equipment of the utility model, a motor is fixedly installed on one side of the treatment chamber, and the output shaft of the motor is fixedly connected to one side of the driving gear through a coupling.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model stores the neutralizing liquid through the liquid outlet cavity, and introduces the neutralizing liquid from the inside of the liquid outlet cavity into the inside of the spray mechanism through the liquid infusion tube. At the same time, the first spray rack and the second spray rack are connected to the liquid infusion tube through the three-way rotary joint, so that the first spray rack and the second spray rack can rotate on both sides of the three-way rotary joint, and through the cooperation between the first driven gear, the second driven gear and the driving gear, the first spray rack and the second spray rack rotate coaxially when the driving gear rotates, and the neutralizing liquid is atomized and sprayed out through the atomizing nozzle;

[0014] When the spray mechanism is working, the first spray rack and the second spray rack rotate coaxially, which can distribute the spray liquid more evenly. The two groups of spray layers can ensure that the flue gas is fully in contact with the absorbent. Even when the flue gas flow rate or distribution is uneven, high-efficiency desulfurization can be maintained and local untreated areas can be reduced. It has the advantage of setting fewer spray layers to ensure the contact area between the sulfide gas and the neutralizing liquid, which solves the problem of needing to stagger multiple groups of spray layers to ensure the contact area between the sulfide gas and the neutralizing liquid, and high equipment cost and installation cost.

The top of the rotary joint 202 is rotatably connected to the second spray rack 203, the three-way rotary joint 202 is fixedly connected to one side of the infusion tube 105, the bottoms of the first spray rack 201 and the three-way rotary joint 202 are fixedly installed with a plurality of atomizing nozzles 204, the top of the first spray rack 201 is fixedly installed with a second driven gear 206, the bottom of the second spray rack 203 is fixedly installed with a first driven gear 205, and one side of the first driven gear 205 and the second driven gear 206 is meshed and connected with a driving gear 207;

[0022] During use, the neutralizing liquid is stored in the liquid outlet chamber 101, and the neutralizing liquid is introduced into the spray mechanism 2 from the liquid outlet chamber 101 through the liquid infusion tube 105. At the same time, the first spray rack 201 and the second spray rack 203 are connected to the liquid infusion tube 105 through the three-way rotary joint 202, so that the first spray rack 201 and the second spray rack 203 can rotate on both sides of the three-way rotary joint 202. When the driving gear 207 rotates, the first spray rack 201 and the second spray rack 203 rotate coaxially through the cooperation between the first driven gear 205, the second driven gear 206, and the driving gear 207, and the neutralizing liquid is atomized and sprayed out through the atomizing nozzle 204;

[0023] When the spray mechanism 2 is working, the first spray rack 201 and the second spray rack 203 rotate coaxially, which can distribute the spray liquid more evenly. The two groups of spray layers can ensure that the flue gas is fully in contact with the absorbent. Even when the flue gas flow rate or distribution is uneven, high-efficiency desulfurization can be maintained, reducing local untreated areas. It has the advantage of setting fewer spray layers to ensure the contact area between the sulfide gas and the neutralizing liquid, and solves the problem of needing to stagger multiple groups of spray layers to ensure the contact area between the sulfide gas and the neutralizing liquid, and the high equipment cost and installation cost.

[0024] Furthermore, the atomizing nozzles 204 on the outer rings of the first spray rack 201 and the second spray rack 203 are both inclined 30° toward the axis of the three-way rotary joint 202;

[0025] During use, the mist sprayed from the outer wall of the first spray rack 201 and the second spray rack 203 is concentrated inward by the tilted atomizing nozzle 204, thereby increasing the neutralization and desulfurization efficiency.

[0026] Furthermore, the demisting mechanism 3 includes a mounting frame 301, a plurality of corrugated plates 303 are fixedly mounted inside the mounting frame 301, and demisting nets 302 are fixedly mounted on both upper and lower sides of the mounting frame 301;

When the flue gas containing droplets passes through the demisting mechanism 3 at a certain speed, the larger droplets will directly hit the corrugated plate 303 due to inertia. Due to the uneven surface, the droplets condense and grow, and are finally captured due to gravity sedimentation, and the demisting efficiency of the demisting mechanism 3 is further improved through the demisting net 302 with a larger contact area.

[0028] Furthermore, an air inlet 103 is fixedly installed at the bottom of the processing chamber 102, and an exhaust hole 104 is fixedly installed at the top of the processing chamber 102;

[0031] During use, the motor 109 provides power for the rotation of the driving gear 207 .

[0032] Furthermore, a pump 106 is fixedly installed inside the infusion tube 105, one end of the infusion tube 105 is fixedly arranged at the bottom of the liquid outlet cavity 101, and a filter 107 is fixedly installed at one end of the infusion tube 105 close to the liquid outlet cavity 101;

[0033] During use, the neutralizing liquid in the liquid outlet cavity 101 is pumped to the inside of the spray mechanism 2 through the infusion tube 105 by the pump 106 for atomization, and the impurities in the neutralizing liquid are filtered through the filter 107 to prevent blockage in the spray mechanism 2.
