Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a discharge treatment device for organic wastewater from esterification reaction. Background Art

[0002] With the rapid development of the chemical industry, esterification reactions are widely used in food additive production, synthetic material manufacturing, etc. However, a large amount of wastewater containing organic matter will be generated during the esterification reaction. These organic wastewaters have complex components and usually contain unreacted alcohols, acids, ester compounds, as well as by-products generated by the reaction, residual catalyst particles, etc. If they are directly discharged without effective treatment, they will cause serious pollution to the environment, threaten the ecological balance of the water body, and affect the safety of living water for surrounding residents.

[0003] At present, biological treatment is usually used to treat organic wastewater generated by esterification reaction. For example, the patent "CN104150679A A land and energy saving esterification wastewater treatment system and method" discloses a technical solution for treating organic wastewater from esterification reaction. However, the above technical solution has the following shortcomings during operation: First, during the pretreatment of organic wastewater generated by esterification reaction, suspended matter and grease in the organic wastewater are usually discharged with the help of devices such as flotation machines. However, the existing flotation devices used in the pretreatment process cannot change the amount of water discharged in real time according to the thickness of suspended matter and grease in the organic wastewater. On the other hand, when the dissolved air release device is blocked or cannot work normally due to other faults, it is impossible to replace the faulty dissolved air release device without stopping the machine, which is not conducive to improving work efficiency; secondly, the current esterification wastewater treatment equipment usually needs to add activated sludge in the aerobic tank to improve the treatment effect, but when the activated sludge becomes inactivated, the staff usually directly add new activated sludge or use circulating pumps and other operating methods to extract the inactivated activated sludge, but these operating methods will cause the difficulty of subsequent sludge treatment to increase sharply on the one hand, and on the other hand, the efficiency is low and may even cause problems such as pump blockage. Summary of the invention

[0004] The purpose of the present invention is to provide an esterification reaction organic wastewater discharge treatment device to solve the problems raised in the prior art.

[0008] Furthermore, two groups of liquid level gauges are relatively arranged below the two ends of the fixed frame, and an adjusting mechanism is arranged on the outer side of one end of the drainage pipe extending into the skimming pipe. The adjusting mechanism is connected to the skimming pipe through a rotating shaft. A collecting tank is arranged on the skimming pipe.

The liquid level gauge and the adjusting mechanism cooperate with each other so that the staff can change the depth of the lower end of the collecting tank extending into the organic wastewater in real time according to the thickness of the suspended matter and grease in the organic wastewater, thereby improving the effect of the pretreatment of the organic wastewater and avoiding the skimming mechanism from being unable to remove the suspended matter and grease in the organic wastewater in time when the organic wastewater flow rate and the impurity content in the organic wastewater change.

[0009] Furthermore, the adjustment mechanism includes an adjustment seat, and an adjustment motor and a gear assembly are arranged inside the adjustment seat. The active end of the gear assembly is connected to the adjustment motor, and the driven end of the gear assembly is connected to the rotating shaft. The rotation angle of the skimming pipe can be controlled by adjusting the motor, the gear assembly and the rotating shaft to change the orientation of the collection tank, thereby facilitating the subsequent skimming pipe to remove suspended matter and grease at different depths.

[0010] Furthermore, the exhaust mechanism includes a support seat and a fixed seat, and the fixed seat is provided with four groups. The four groups of fixed seats are evenly arranged on the support seat, and each group of fixed seats is provided with a group of dissolved air releasers.

At this time, the staff can quickly locate a group of dissolved air releasers that has failed for subsequent maintenance.

[0011] Furthermore, the exhaust mechanism also includes a connecting pipe and a five-way pipe, a group of connecting pipes is arranged below each group of fixed seats, one end of the five-way pipe is connected to the dissolved air system, and the other four ends of the five-way pipe are connected to the four groups of connecting pipes through four groups of valves respectively, each group of fixed seats is detachably mounted on the support seat through a first bolt, each group of connecting pipes is connected to the five-way pipe and the fixed seat through a second bolt, a group of drain ports are arranged at the side ends of each group of connecting pipes, and a group of sealing covers are arranged in each group of drain ports. Compared with the air flotation components currently used in wastewater discharge treatment equipment, the present invention is provided with a movable seat, which is arranged at the middle position of the support seat, and a sealing assembly is arranged at the side end of the movable seat, and a reversing motor is arranged below the movable seat, and the movable seat is controlled to rotate in the pretreatment tank by the reversing motor. During the operation of the present invention, if a failure of a certain group of dissolved air releasers is detected, the worker The operator can drive the sealing component to move to the top of the malfunctioning dissolved air releaser through the reversing motor and the movable seat, and then open the sealing component, and at the same time close a group of valves matched with the malfunctioning dissolved air releaser, and then open a group of sealing covers matched with the malfunctioning dissolved air releaser, and connect the drain port with the external pumping device, and separate the malfunctioning dissolved air releaser from the external environment through the sealing component, and pump out the organic wastewater isolated inside the sealing component through the external pumping device, so that the operator can remove the malfunctioning dissolved air releaser and the fixing seat from the bottom of the pretreatment tank and replace it with a new dissolved air releaser. Through the above technical scheme, the present invention can replace the malfunctioning dissolved air releaser without affecting the normal pretreatment of organic wastewater, which improves the working efficiency on the one hand, and avoids the water volume impact and the re-sedimentation of suspended matter on the wastewater discharge treatment equipment during the shutdown process on the other hand.

[0012] Furthermore, the sealing assembly includes a sealing frame, and the side ends of the sealing frame are relatively provided with two groups of openings, a group of telescopic grooves are provided above each group of openings, a group of sealing plates are provided in each group of telescopic grooves, and the sealing plates are movably installed in the telescopic grooves through compression springs, two groups of liquid storage tanks are provided between the two groups of telescopic grooves, a group of pistons and hydraulic oil are provided in each group of liquid storage tanks, each group of telescopic grooves is connected to a group of liquid storage tanks, and a cylinder is provided between the two groups of liquid storage tanks, and the cylinder is a double-headed cylinder, and the two ends of the cylinder are respectively connected to the two groups of pistons When the sealing assembly in the present invention is not in operation, the sealing plate is located inside the telescopic groove.

Under the action of the hydraulic pressure, the two groups of sealing plates extend out of the telescopic grooves that match them, and the malfunctioning dissolved air releaser is separated from the external environment by the two groups of sealing plates, so that the malfunctioning dissolved air releaser can be replaced without stopping the machine.

At this time, the activated sludge in the aerobic chamber can be intercepted by the filter screens arranged on the two groups of movable plates. When the lifting frame rises to a position close to the maintenance port of the aerobic chamber, the staff can clean up the invalid activated sludge on the filter screen and add new activated sludge to facilitate the subsequent normal treatment of the organic wastewater.

When the sealing assembly moves to the top of the malfunctioning dissolved air releaser 3161, the staff can turn on the cylinder 3176 to drive the two groups of pistons 3174 to move, thereby allowing the hydraulic oil in the two groups of liquid storage tanks 3175 to enter the two groups of telescopic grooves. Under the action of the hydraulic pressure, the two groups of sealing plates 3173 extend out of the corresponding telescopic grooves, and the malfunctioning dissolved air releaser 3161 is separated from the external environment by the two groups of sealing plates 3173, so that the malfunctioning dissolved air releaser 3161 can be replaced without stopping the machine.

[0028] like Figure 2 , Fig.10 As shown, the collecting mechanism includes a lifting frame 5 and a mounting frame 6. The mounting frame 6 is arranged at the top of the inner part of the aerobic chamber. A winding device is arranged in the mounting frame 6. The winding device is connected to the lifting frame 5 through a lifting rope 51. Two groups of movable plates 52 are arranged in the lifting frame 5. A group of filter screens 521 are arranged on each group of movable plates 52.

At this time, the activated sludge in the aerobic chamber can be intercepted by the filter screens 521 arranged on the two groups of movable plates 52. When the lifting frame 5 rises to a position close to the maintenance port of the aerobic chamber, the staff can clean up the invalid activated sludge on the filter screen 521 and add new activated sludge so that the subsequent organic wastewater can be treated normally.

The positions of the two groups of movable plates 52 are controlled by the two groups of opening and closing motors. When the collecting mechanism in the present invention is in a non-working state, the lifting frame 5 is located at the lower end of the interior of the aerobic chamber, and the two groups of movable plates 52 are away from each other and form an angle of ninety degrees with the lifting frame 5 to prevent the filter screen 521 from hindering the rise of bubbles generated by the aeration element 41. When the collecting mechanism is in a working state, the two groups of movable plates 52 are controlled by the two groups of opening and closing motors to approach each other and close, so that the filter screen 521 can intercept the activated sludge in the aerobic chamber when the lifting frame 5 rises later.

[0030] The working principle of the present invention is as follows: before work, the water inlet pipe 2 is connected to the external esterification reaction organic wastewater discharge device. When the organic wastewater is discharged into the pretreatment tank 3, the dissolved air water is transported into the pretreatment tank 3 through the dissolved air system 32 and the exhaust mechanism, so that the grease and suspended matter in the organic wastewater float to the surface of the water body, and the grease and suspended matter on the surface of the water body are removed by the skimming mechanism 31 to facilitate the subsequent treatment of the organic wastewater. The suspended matter and grease thickness in the pretreatment tank 3 are detected by a liquid level meter, and the depth of the lower end of the collecting tank 3191 extending into the organic wastewater is changed by the adjusting mechanism. The cooperation of the liquid level meter and the adjusting mechanism enables the staff to change the depth of the lower end of the collecting tank 3191 extending into the organic wastewater in real time according to the thickness of the suspended matter and grease in the organic wastewater, thereby improving the effect of the pretreatment of the organic wastewater. During the process, if a certain group of dissolved air releasers 3161 is detected to have a fault, the staff can drive the sealing assembly to move to the top of the faulty dissolved air releaser 3161 through the reversing motor 3171 and the movable seat 317, and then open the sealing assembly, and at the same time close a group of valves 3163 that match the faulty dissolved air releaser 3161, and then open a group of sealing covers that match the faulty dissolved air releaser 3161, and connect the drain port to the external pumping device, and separate the faulty dissolved air releaser 3161 from the external environment through the sealing assembly, and pump out the organic wastewater isolated inside the sealing assembly through the external pumping device, so that the staff can remove the faulty dissolved air releaser 3161 and the fixed seat 316 from the bottom of the pretreatment tank 3 and replace it with a new dissolved air releaser 3161.
