Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, and more particularly to an ultrasonic hydration catalyst filter. Background Art

[0002] Hydration to produce cyclohexanol is a chemical production method primarily used to synthesize cyclohexanol from cyclohexane. Cyclohexanol is an important organic chemical raw material widely used in the production of nylon fibers, engineering plastics (such as polyamide), plasticizers, solvents, and other products. The catalyst filter is the primary equipment for the hydration reaction.

[0003] Chinese patent application number 201820475879.9 discloses a catalyst filter, which includes a cylinder, an upper head disposed at the upper end of the cylinder, a lower head disposed at the lower end of the cylinder, and a sealing flange for connecting the upper head and the cylinder. A row pipe is provided between the cylinder and the lower head, and the row pipe is composed of interconnected horizontal and vertical pipes. A plurality of microporous filter elements with one end closed are vertically mounted on the row pipe, and the microporous filter elements are connected to the row pipe. A connected cavity is formed between the upper head, the cylinder, and the lower head. A mother liquor inlet and a slag outlet are provided at the lower end of the lower head. The outlet of the row pipe extends out of the cylinder to form a filtered liquid outlet. A nitrogen inlet is provided on the upper head. This catalyst filter flushes the adhesions on the surface of the filter element through a spray device, thereby flushing them off the surface of the filter element to ensure the cleanliness of the filter element. However, the following problems still exist:

[0004] 1. The spray device relies entirely on the impact of water flow to clean the adhesions. The water flow has a certain impact effect only when it first contacts the adhesions. After that, it can only flow downward along the filter element. The ability to remove adhesions during flow is limited, so the adhesions at the bottom cannot be effectively cleaned. At the same time, the spray angle of the water flow is limited, and there will be dead corners, which cannot play a good cleaning role.

[0005] 2. The material entering the tank will move directly toward the filter element. Since the material contains large particles of catalyst, large and small particles of catalyst will adhere to the filter element together, thereby increasing the cleaning frequency of the filter element, shortening the effective use time of the filter element, and reducing production efficiency.

[0006] Therefore, it is necessary to propose an ultrasonic hydration catalyst filter to solve the above problems. Utility Model Content

[0007] In response to the above problems, the present invention provides an ultrasonic hydration catalyst filter; it has the function of improving the cleaning of the filter element through the ultrasonic device, reducing the adhesion of pollutants on the filter element, and at the same time, improving the cleaning efficiency of the detached pollutants.

[0008] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0009] An ultrasonic hydration catalyst filter includes a tank body, which is sequentially provided with a discharge portion, a cleaning portion, a collection portion, and a sewage discharge portion from top to bottom. The cleaning portion includes a reflective ring plate connected to the tank body, a fixing plate connected to the top of the reflective ring, and a circumferential array of filter elements and ultrasonic devices connected to the bottom of the fixing plate. The ultrasonic devices and filter elements are arranged in an annular staggered manner. A spray pipe arranged toward the filter element is connected to the inner wall of the tank body.

[0010] The collecting part is connected with a tubular distributor and a coalescing plate. The coalescing plate is located on the top of the tubular distributor. The feed end of the tubular distributor extends out of the tank body and is connected with an external feed end.

[0011] Preferably, the bottom of the tank body is connected to a kettle bottom valve extending into the sewage discharge part, the bottom end of the kettle bottom valve is connected to a sewage pipe, the sewage discharge part is connected to a spoiler rod and a sewage suction pipe, one end of the spoiler rod extends out of the tank body and is connected to the external water supply end, the other end of the spoiler rod is connected to a stirring pipe located in the sewage discharge part, the water spray port of the stirring pipe is arranged toward the kettle bottom valve, the sewage suction pipe extends deep into the sewage discharge part, and the other end is connected to an external sewage pump.

[0012] Preferably, a manhole for inspection, a steam port and a sight glass port are installed on the side wall of the tank body, and a discharge pipe, a vent port and a nitrogen port are connected to the top of the discharge part.

[0013] Preferably, the coalescing plate comprises a mounting ring and equally spaced corrugated plates fixed in the mounting ring, and guide columns are connected to the bending parts of two adjacent corrugated plates.

[0014] Preferably, each upwardly inclined surface of the corrugated plate is provided with a guide groove, and the guide groove is connected to the guide column.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This device is equipped with an ultrasonic device in the tank, which is set towards the filter element. The ultrasonic waves emitted can generate a large number of tiny bubbles in the cleaning liquid. When the sound pressure reaches a certain value, the bubbles grow rapidly and then suddenly close. When the bubbles close, shock waves are generated, which generate thousands of atmospheric pressures around them. The explosive shock waves during closure destroy insoluble dirt and disperse them in the cleaning liquid, which can effectively loosen and remove pollutants and sediments on the filter element. It is more thorough than simple water flushing. At the same time, multiple ultrasonic devices are arranged in a circular array, and the ultrasonic waves emitted are intertwined, which can improve the cleaning effect.

[0017] 2. This device is equipped with a sewage extraction pipe and a stirring pipe in the sewage discharge part. The stirring pipe can impact the pollutants attached to the bottom wall, and the sewage extraction pipe can accelerate the discharge of pollutants when there are too many pollutants, thereby improving the cleaning efficiency.

[0018] 3. This device is equipped with guide columns and guide grooves on the corrugated plate. The guide grooves guide the pollutants, which can accelerate the separation of pollutants from the coalescing plate. At the same time, the guide columns play a supporting role, thereby improving the strength of the corrugated plate and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3The ultrasonic hydration catalyst filter includes a tank body, which is provided with a discharge part 101, a cleaning part 102, a collection part 103 and a sewage discharge part 104 from top to bottom. The material to be filtered will first enter the collecting part 103, move upward through the cleaning part 102 and be discharged from the discharge part 101. The cleaning part 102 cleans the intercepted impurities, and the cleaned attachments finally fall into the sewage discharge part 104 at the bottom. The cleaning part 102 includes a reflection ring plate 105 connected to the tank body, and the top of the reflection ring is connected to a fixing plate 106, which is fixed on the reflection ring plate 105. The bottom is used to install a filter element 107 and an ultrasonic device 122. When cleaning is required, the ultrasonic device 122 emits ultrasonic waves to clean the filter element 107, and cleans away the pollutants attached to the filter element 107. The bottom of the fixing plate 106 is connected to There are filter elements 107 and ultrasonic devices 122 arranged in a circular array. The filter elements 107 and ultrasonic devices 122 are arranged in a circular array. The emitting surfaces of two adjacent ultrasonic devices 122 are arranged facing each other. When the two ultrasonic waves come into contact, the cleaning ability of the adhesion on the filter element 107 can be improved. The filter element 107 adopts an asymmetric outer light metal powder sintered filter element with high precision, large flux, and smooth surface, which reduces the adhesion of the catalyst on the surface of the filter element and has a good cleaning effect. The filter element membrane layer is also equivalent to a coalescence layer, which can intercept part of the moisture. The ultrasonic device 122 and the filter element 107 are arranged in a staggered manner in a ring. The inner wall of the tank is connected to a spray pipe 108 arranged towards the filter element 107. The spray pipe 108 on the top sprays out a cleaning liquid, which cleans the filter element 107, but it will only be used when the gap on the filter element 107 is blocked.

[0026] Specifically, when in use, the cleaning liquid inside the tank body will immerse the filter element 107, so that the filter element 107 can be cleaned by the ultrasonic device 122. A flip-type liquid level gauge is provided on the tank body to facilitate understanding of the internal page situation;

[0027] refer to Figure 1, the collecting part 103 is connected with a tubular distributor 109 and a coalescing plate 110. The tubular distributor 109 is a feeding device for uniformly conveying the material into the tank body. A distributor is provided at the material inlet of the filter to prevent the disturbance of the sewage discharge part 104 at the bottom of the filter by the side feed, thereby enhancing the natural sedimentation effect of the catalyst. The coalescing plate 110 is located at the top of the tubular distributor 109, and the coalescing plate 110 is provided at the bottom of the filter element, so that the trace amount of catalyst and water in the material are preliminarily coalesced and agglomerated at the coalescing plate 110 and the natural sedimentation is accelerated, thereby reducing the interception pressure of the filter element to a certain extent, reducing the water content in the subsequent process section, and reducing the subsequent steam consumption. Since the catalyst is added to the reaction mixture in solid form, in order to recover these expensive catalysts and prevent them from leaving the reactor with the product flow, the coalescing plate 110 can help capture and condense these fine catalyst particles, thereby improving the recovery rate of the catalyst. The feed end of the tubular distributor 109 extends out of the tank body and is connected to the external feed end.

[0028] Specifically, refer to Figure 1 The bottom of the tank body is connected to a bottom valve 111 extending into the sewage discharge part 104. When cleaning, the pollutants will fall into the sewage discharge part 104 at the bottom, and the spoiler rod 113 sprays cleaning water to enable the pollutants to be discharged through the sewage pipe 112. When there are too many pollutants in the sewage discharge part 104, the internal pollutants can be extracted through the sewage extraction pipe 114 to improve the cleaning efficiency. The bottom end of the bottom valve 111 is connected to the sewage discharge pipe 112, and the sewage discharge part 104 is connected to the spoiler rod. 113 and the sewage suction pipe 114, one end of the spoiler rod 113 extends out of the tank body and is connected to the external water supply end, the other end of the spoiler rod 113 is connected to the stirring pipe 115 located in the sewage discharge part 104, and the water spray port of the stirring pipe 115 is set toward the bottom valve 111 of the kettle. The sprayed water flow will have an impact on the pollutants attached to the bottom, thereby separating them from the inner wall, making it easier to discharge them. The sewage suction pipe 114 goes deep into the sewage discharge part 104, and the other end is connected to the external sewage pump.

[0029] Specifically, refer to Figure 1 A maintenance manhole 116, a steam port and a sight glass port are installed on the side wall of the tank body. The maintenance manhole 116 is convenient for workers to inspect the interior. The top of the discharge part 101 is connected to a discharge pipe 117, a vent and a nitrogen port. The material filtered by the filter element 107 will be discharged from the discharge pipe 117. The nitrogen port is used to transport nitrogen to the interior. The introduction of nitrogen can replace the air inside the filter. The nitrogen port is used to replace the oxygen in the tank before the equipment is put into use. Because the liquid material is a high-temperature flammable and explosive medium, the oxygen in the tank must be replaced with nitrogen first. The vent is used for ultrasonic cleaning and pressure relief during maintenance, because ultrasonic cleaning is more effective under normal pressure.

[0030] When cleaning, pollutants tend to fall on the coalescing plate 110 and accumulate. The following provides a structure that can guide the falling pollutants and reduce the pollution from clogging the coalescing plate 110: Specifically, refer to Figure 3 The coalescing plate 110 includes a mounting ring 118 and equally spaced corrugated plates 119 fixed in the mounting ring 118. The corrugated plates 119 are installed in the tank body through the mounting ring 118. The bending parts of two adjacent corrugated plates 119 are connected with guide columns 120. The guide columns 120 guide the pollutants so that they can flow smoothly to the next layer and finally fall into the sewage discharge part 104, thereby avoiding the accumulation of a large amount of pollutants on the coalescing plate 110.

[0031] Specifically, refer to Figure 3 Each upward inclined surface of the corrugated plate 119 is provided with a guide groove 121, which guides toward the guide column 120. When the pollutants flow with the water flow, they will be guided by the guide groove 121 to the guide column 120 and flow from the guide column 120 to the bottom. The guide groove 121 and the guide column 120 are connected.

[0032] In this embodiment, the material to be filtered enters the tank body from the tubular distributor 109, then moves upward, is filtered by the filter element 107, and is discharged from the discharge pipe 117 at the top. When the filter element 107 needs to be cleaned, cleaning liquid is added to the tank body to immerse the filter element 107, and then the ultrasonic device 122 is started for cleaning. The fallen pollutants are guided by the guide groove 121 on the corrugated plate 119 to the guide column 120, and finally fall into the sewage discharge part 104 at the bottom. The accumulated pollutants are cleaned out through the sewage pipe 112 and the sewage extraction pipe 114. At the same time, the water flow sprayed from the stirring tube 115 can impact the pollutants attached to the bottom wall to improve the cleaning efficiency.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
