Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a wastewater treatment device for chemical production. Background Art

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water, and other wastewater discharged during chemical production. If these wastewaters are discharged without treatment, they will cause different properties and varying degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. The substances contained in the water used in chemical production and processing are relatively complex, including many toxic and irritating substances. At the same time, the wastewater also contains large amounts of phosphorus, nitrogen, sulfur and other substances, which have strong oxygen-consuming properties, are highly polluting, and are difficult to decompose. Existing wastewater treatment devices usually directly add flocculants to the wastewater during use, but this will also cause the flocculants to spread throughout the mixing tank, which takes a certain amount of time. This will increase the mixing time and reduce the working efficiency of the device.

[0003] A Chinese utility model patent, publication number CN221319552U, discloses a wastewater treatment device for chemical production. By arranging a feed pipe, a first rotating joint, a fixed column, a first helical gear, a second helical gear, a diverter pipe, a nozzle, a second propeller, a second rotating joint, a first connecting pipe, a second connecting pipe, and a third rotating joint, the device directly directs the flocculant into the middle end of the mixing drum, forcing the second helical gear to rotate. Simultaneously, the connecting sleeve drives the sealing box to rotate, thereby squeezing the second helical gear through the first helical gear and causing it to rotate. This allows the diverter pipe to rotate as the entire structure rotates, driving the nozzle and the second propeller to rotate, thereby accelerating the dispersal of the flocculant in the wastewater. However, the device also has some other problems. For example, the device does not classify and treat impurities produced by the reaction of pollutants and reagents during discharge after stirring.

[0073] In the present technical solution, in order to facilitate the treatment of solid waste residue after the flocculant reaction, a storage plate 310 is provided at the lower end of the solid chamber 300. In this way, the solid waste residue flows into the solid chamber 300 through the inclined plate and finally falls on the storage plate 310. A heating plate 320 is provided on the bottom plate of the solid chamber 300. The heating plate 320 can dry the solid waste residue on the storage plate 310. The moisture during drying can enter the inclined tube 520 for condensation. A 2 mm baffle is provided on the inner wall of the inclined tube 520 above the filter port 530.

In addition, a revolving door that can be opened or closed is provided on one side of the solid chamber 300, so that the residue inside the solid chamber 300 can be easily removed for subsequent treatment.

[0074] This embodiment provides a wastewater treatment device for chemical production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] like Figure 1-Figure 3 As shown, in this embodiment, a valve 280 is connected between the connecting pipe 510 and the inclined pipe 520 .

[0079] In the present technical solution, in order to facilitate the discharge of reacted substances according to the state of the reaction inside the reaction chamber 200, a valve 280 is fixedly arranged between the connecting pipe 510 and the inclined pipe 520. When the flocculant reacts with the wastewater inside the reaction chamber 200, the valve 280 is closed to allow the raw materials to react fully. After the reaction time is sufficient, the valve 280 is opened to discharge the solid waste residue and liquid wastewater inside the reaction chamber 200 from the connecting pipe 510 to the inside of the inclined pipe 520, thereby facilitating classification. At the same time, the flow velocity inside the inclined pipe 520 can be controlled by the valve 280 to prevent the flow velocity from being too high, causing the wastewater to follow the waste residue into the interior of the solid chamber 300.

[0080] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
