Abstract
Description
Technical Field
[0001] The utility model patent relates to waste acid treatment equipment, specifically to a waste acid sulfidation reaction device. Background Art
[0002] At present, the more mature and commonly used waste acid treatment process in copper smelting enterprises is the sulfidation process. The sulfidation process mainly removes copper and arsenic in waste acid under acidic conditions by adding sulfiding agents, producing copper sulfide and arsenic sulfide precipitation, and achieving the purpose of efficient removal of heavy metals under acidic conditions.
[0003] like Figure 1 As shown, in the prior art, a short pipe 2 and a tee (or valve) 3 are generally connected to the bottom of a reaction tank 1 for containing dirty acid wastewater, and the dirty acid and the sulfiding agent are pumped into the reaction tank 1 through two opposite ports on the tee 3 for sulfidation reaction. During the process, due to the relative arrangement of the inlet ports of the dirty acid and the sulfiding agent, under the action of the liquid counterpressure, the sulfiding agent with a relatively small displacement is difficult to be pumped smoothly into the reaction tank 1, affecting the normal treatment of the dirty acid, and even failing to be pumped out, resulting in damage to the pump body and leakage, which further leads to excessive heavy metal ions in the reaction tank 1. Summary of the invention
[0004] The utility model provides a waste acid sulfurization reaction device, which can smoothly pump the waste acid and the sulfurizing agent into a reaction tank for full mixing reaction.
[0005] In order to achieve the above purpose, the technical solution adopted is: a waste acid sulfurization reaction device, including a reaction tank, the bottom of the reaction tank is connected to a cylindrical mixing section, and the introduction directions of the waste acid inlet pipe and the sulfurizing agent inlet pipe connected to the mixing section are in a high and low staggered avoidance position.
[0006] Compared with the prior art, the technical effect of the utility model is that the introduction directions of the dirty acid inlet pipe and the sulfiding agent inlet pipe avoid each other and form a high and low staggered posture, so that during the pumping process, the dirty acid and the sulfiding agent will not have a direct impact on each other and cause the sulfiding agent to be difficult to pump out. Both the dirty acid and the sulfiding agent can be smoothly pumped into the reaction tank, ensuring the treatment quality of the dirty acid wastewater. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the bottom structure of the dirty acid reaction tank in the prior art;
[0008] Figure 2 This is a schematic diagram of the bottom structure of the reaction tank of the utility model;
[0009] Figure 3 This is a bottom view of the mixing section. DETAILED DESCRIPTION
[0010] The following is combined with Figure 1-3 And related content, the utility model is further described in detail:
[0011] A waste acid sulfidation reaction device comprises a reaction tank 10, the bottom of which is connected to a cylindrical mixing section 30, and the introduction directions of a waste acid inlet pipe 31 and a sulfiding agent inlet pipe 32 connected to the mixing section 30 are in a high-low staggered avoidance position.
[0012] In the above scheme, the introduction directions of the dirty acid inlet pipe 31 and the sulfiding agent inlet pipe 32 avoid each other and present a high-low staggered posture, so that when the dirty acid and the sulfiding agent are pumped into the mixing section 30, the two will not produce a direct impact and cause the sulfiding agent to be difficult to pump out. The dirty acid and the sulfiding agent can be smoothly pumped into the mixing section 30 for mixing, and further sent to the reaction tank 10 for sufficient reaction, thereby ensuring the treatment quality of the dirty acid wastewater.
[0013] As a preferred solution, the inlet of the sulfiding agent inlet pipe 32 on the mixing section 30 is located above the inlet of the waste acid inlet pipe 31. The waste acid must pass through the sulfiding agent inlet when flowing from bottom to top, which can ensure that the waste acid and the sulfiding agent are contacted and mixed before being sent to the reaction tank 10. Compared with the solution in which the sulfiding agent inlet is located below the waste acid inlet, it is basically impossible for part of the waste acid to overflow directly from the discharge port of the reaction tank 10 without contacting and reacting with the sulfiding agent.
[0014] Furthermore, combined with Figure 3 As shown, the core of the waste acid inlet pipe 31 and the core of the vulcanizing agent inlet pipe 32 are arranged along the tangential and radial directions of the mixing section 30. When the waste acid is pumped into the mixing section 30, the waste acid is pumped into the mixing section 30 along the tangential direction of the mixing section 30 and flows along the inner wall of the cylindrical mixing section 30 to form a high-speed vortex, which can promote the mixing degree of the vulcanizing agent and the waste acid, thereby ensuring that the two can be fully mixed and reacted.
[0015] As a preferred solution, the core of the mixing section 30 is located in the plumb direction.
[0016] like Figure 2 As shown, the bottom of the reaction tank 10 is connected to a short tube 20, and the mouth of the mixing section 30 is connected to the bottom mouth of the short tube 20 through a flange. The short tube 20 serves as a connection transition, and the bottom inlet of the reaction tank 10 is adapted to the mouth of the short tube 20. The short tube 20 can be made of a pipe body with a larger diameter to avoid the situation where the size of the bottom inlet of the reaction tank 10 becomes smaller after scaling, which makes it difficult to feed the mixed solution of the dirty acid and the sulfiding agent into the reaction tank 10 for reaction.
[0017] In order to facilitate the subsequent sewage discharge from the reaction tank 10 and the mixing section 30, the bottom of the mixing section 30 is connected to a sewage pipe 33 connected to the interior thereof, and a corresponding valve can be provided to control the sewage pipe 33 to discharge sewage, which is convenient for subsequent maintenance.
