Description

Technical Field

[0001] The invention relates to the technical field of chemical production wastewater treatment equipment, and in particular to a fine chemical production process wastewater treatment device. Background Art

[0002] With the rapid development of industrialization, the amount of wastewater is also gradually increasing; fine chemical production wastewater usually contains impurities such as suspended solids and debris particles. The presence of these impurities affects the subsequent treatment process of the wastewater.

[0003] At present, the main methods used to deal with this type of impurities are grid interception and flotation tank treatment. Among them, flotation tanks have gradually become the mainstream method for treating the above impurities due to their advantages of high treatment efficiency and significant effects.

[0004] However, the current flotation tank has the following main problems: first, the particulate impurities in the wastewater move upward with the bubbles released by the dissolved air releaser and are cleaned by the scraper assembly. However, as the number of particulate impurities increases, the impurities will be adsorbed on the scraper assembly, resulting in a poor scraping effect. The scraper assembly needs to be cleaned after shutdown, affecting the wastewater treatment efficiency; second, when the scraper assembly scrapes the impurities floating on the top surface of the wastewater, if the bubbles are broken and the impurities are not scraped off in time, the impurities may settle back into the wastewater, affecting the wastewater treatment effect. Summary of the invention

[0005] In view of this, the present invention provides a fine chemical production process wastewater treatment device, specifically a wastewater treatment device provided with a guide pipe, an interception plate, an interception net, a float A and a float B. The wastewater treatment device has the advantages of reasonable design, strong practicality and convenient use. The use of the wastewater treatment device can reduce the probability of particulate impurities returning to the guide pipe, thereby improving the wastewater treatment efficiency and treatment effect.

[0006] The technical solution of the present invention is as follows: A fine chemical production process wastewater treatment device comprises a treatment tank, wherein the treatment tank comprises a tank body and a tank cover; A guide pipe is provided on the unloading section of the tank body, and the bottom end of the guide pipe is sealedly connected to the unloading section of the tank body; A water inlet pipe A is provided on the unloading section and is located below the guide pipe; A dissolved air releaser is arranged in the guide pipe, and the dissolved air releaser is close to the bottom end of the guide pipe; Wastewater enters the unloading section of the tank from the water inlet pipe A. The bubbles released by the dissolved air releaser carry the particle impurities upward along the guide pipe and are discharged from the top of the guide pipe. An interception plate is provided on the outside of the guide tube, and the interception plate is located in the upper middle of the guide tube; The bottom end of the interception plate is arranged along the circumference of the flow guide pipe and is sealed and connected to the outer side surface of the flow guide pipe; An interception net is provided at the top of the interception plate, and the interception net is located above the top of the guide pipe; The area surrounded by the interception plate, the outer side of the guide pipe and the interception net is the impurity removal chamber; The impurity removal chamber is provided with a float A and a float B, an adsorption layer is provided on the outside of the float A, and bristles are provided on the outside of the float B; When wastewater is discharged from the top of the guide pipe, the bubbles are broken quickly due to the pressure change, so that most of the particulate impurities carried by the bubbles are settled in the impurity removal chamber. The unsettled particulate impurities are adsorbed by the float A when entering the impurity removal chamber, thereby avoiding the particulate impurities from returning to the guide pipe again to the greatest extent, thereby improving the wastewater treatment effect; the bristles on the float B will clean the impurities adsorbed by the float A as the water flow fluctuates, so that some of the particulate impurities attached to the surface of the float A will further settle in the impurity removal chamber, thereby improving the wastewater treatment efficiency; and the wastewater containing no particulate impurities is discharged through the interception net and enters the tank body.

[0007] Preferably, the guide pipe is tapered from bottom to top, that is, it is a structure that is small at the top and large at the bottom. This arrangement gradually increases the speed of the liquid flowing upward. At the moment of discharge from the guide pipe, the impurity removal chamber outside the guide pipe increases instantly, causing the bubbles to break quickly, so that the particulate impurities carried by the bubbles will settle more quickly in the impurity removal chamber, thereby improving the wastewater treatment efficiency.

[0008] Preferably, the interception plate includes an M section, an N section and an F section connected in sequence from bottom to top, the M section is conical, the N section is cylindrical, and the F section is conical; the M section is connected to the guide tube, and the interception net is connected to the top of the F section; the setting of the interception plate M section allows the particulate impurities to settle as quickly as possible in the impurity removal chamber, and the settled particulate impurities are better gathered at the bottom of the impurity removal chamber, reducing the particulate impurities from participating in the impurity removal process again, thereby improving the impurity removal efficiency and effect; the setting of the N section provides a larger space for the rapid discharge of wastewater from the top of the guide tube, which is conducive to the rapid entry of bubbles containing particulate impurities into the N section and breaking, thereby reducing the particulate impurities from returning to the guide tube again, thereby improving the treatment efficiency and effect of the wastewater; the setting of the F section allows the float A and the float B to play their role in the N section as much as possible, reducing the particulate impurities from returning to the guide tube.

[0009] Preferably, the top of the N segment is lower than the top of the guide tube, which can further reduce the return of particulate impurities into the guide tube and improve the treatment effect and efficiency.

[0010] Preferably, the diameter of the float A is larger than the diameter of the float B, and the distance between the interception net and the top of the diversion tube is smaller than the diameter of the float B; the diameter of the float A is larger than the diameter of the float B, so that the float B can flexibly shuttle between the floats A, thereby cleaning the particulate impurities on the surface of the float A; the distance between the interception net and the top of the diversion tube is smaller than the diameter of the float B, which can prevent the float B from entering the diversion tube and ensure the smooth progress of the wastewater treatment process.

[0011] Preferably, in order to promote the movement of floats A and B in the impurity removal chamber and promote the sedimentation of granular impurities, a water inlet pipe B is provided in the impurity removal chamber, and the water inlet pipe B is tangent to the inner side surface of section N; the water entering the impurity removal chamber from the water inlet pipe B promotes the movement of floats A and B in section N, which is beneficial to the falling off and sedimentation of granular impurities on float A.

[0012] Preferably, a drain pipe A is provided on the unloading section of the tank body, and the drain pipe A is located above the bottom end of the guide pipe; the drain pipe A is connected to a water pump, and the outlet of the water pump is divided into two paths, one connected to the water inlet pipe B, and the other connected to the collection tank.

[0013] Preferably, a valve A is provided on the connecting pipeline between the water pump and the water inlet pipe B, and a valve B is provided on the connecting pipeline between the water pump and the collection tank; the water flow state of the water inlet pipe B is flexibly controlled according to the movement state of the float A in the impurity removal chamber.

[0014] Preferably, a drain pipe B is provided on the M section, and the drain pipe B is arranged obliquely; a valve C is provided on the drain pipe B, which is conducive to timely cleaning of particulate impurities according to the impurity sedimentation conditions.

[0015] Preferably, an exhaust pipe is provided on the top surface of the tank cover, a discharge pipe is provided on the bottom surface of the discharge section of the tank body, and a valve D is installed on the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the guide tube, it is beneficial to limit the direction of the bubbles and the particulate impurities they carry, so that the particulate impurities can enter the impurity removal chamber according to the setting for collection and treatment, reducing the probability of the particulate impurities returning to the guide tube, and improving the treatment efficiency and treatment effect; by setting the interception plate and the interception net, on the one hand, it is beneficial for the wastewater without particulate impurities to enter the inner side of the tank body and the outer side of the guide tube from the interception net for collection, and on the other hand, the impurity removal chamber formed provides space for the sedimentation and treatment of particulate impurities, thereby improving the treatment effect of particulate impurities; the setting of the float A can produce an adsorption effect on the floating particulate impurities, and the float B can collide with the float A when flowing with the water, reducing the impurities on the surface of the float A, so that the float A maintains a high adsorption effect. The above settings make the treatment device have the advantages of reasonable design, strong practicality and easy use.
