Description

Technical Field

[0001] The utility model relates to the technical field of C4 pretreatment devices, in particular to a post-ether C4 raw material pretreatment device. Background Art

[0002] Etherified C4 raw materials usually refer to the C4 remaining after etherification reaction. In petroleum refining and chemical production, etherification reaction is mainly used to react isobutylene with methanol to produce methyl tert-butyl ether, which is a high-octane gasoline additive. After the etherification reaction, the remaining C4 component is the etherified C4. When the etherified C4 raw materials are used, a deoxygenation device needs to be used for pretreatment operations to facilitate the subsequent further processing of the etherified C4 raw materials.

[0003] A deoxygenation device is required when using the post-etherification C4 raw material. Among them, the "A post-etherification C4 raw material pretreatment device" disclosed with the announcement number "CN210176755U" has solved the various technical disadvantages of the existing process flow, complex process, high investment and high operating cost.

[0004] However, there are still many defects in the actual use of C4 raw material pretreatment devices with similar structures, such as: the replacement cycle of the adsorption material in the existing technology is short, and the operator needs to replace it frequently, which increases the frequency of manual intervention and the complexity of operation. At the same time, frequent replacement of the adsorption material leads to higher material consumption, which not only increases production costs, but also increases the demand for raw materials. Therefore, a post-ether C4 raw material pretreatment device is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pretreatment device for post-etherification C4 raw materials to solve the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pretreatment device for C4 raw materials after etherification, comprising a bottom plate, an adsorption tower fixedly mounted on one side of the top of the bottom plate, a pre-filtering mechanism fixedly mounted on one side of the adsorption tower for filtering particles and impurities doped in the C4 raw materials after etherification, and an adsorbent reset mechanism fixedly mounted on the bottom of the other side of the adsorption tower;

[0007] The adsorbent resetting mechanism includes a filter box, an air pump is fixedly installed on one side of the filter box through a pipe fitting, a heating box is fixedly installed on one side of the air pump through a pipe fitting, coiled heating wires are equidistantly installed inside the heating box, a one-way valve pipe fixedly connected to one side of the adsorption tower is fixedly installed on the top of the heating box, a storage tank is fixedly installed on one side of the filter box, and a solenoid valve pipe fixedly connected to the one-way valve pipe is fixedly installed on the top of the storage tank;

[0008] The pre-filter mechanism includes a storage box, and a fixed box is fixedly installed on the top of the storage box.

[0009] Preferably, two groups of bolts are threadedly installed on both sides of the bottom of the base plate, and nuts are fixedly installed on the tops of the bolts.

[0010] Preferably, a plurality of groups of metal plates are fixedly installed inside the adsorption tower, and the spaces between the plurality of groups of metal plates are filled with an oxygen-containing compound removal adsorbent.

[0011] Preferably, two groups of nanoporous plates are fixedly installed inside the fixed box, a water pump is fixedly installed at the bottom of the storage box, and a delivery pipe fixedly connected to the top of the adsorption tower is fixedly installed on one side of the water pump.

[0012] Preferably, a replenishing pipe is fixedly installed on one side of the storage tank, and a valve is fixedly installed on one end of the replenishing pipe.

[0013] Preferably, a fixing block is fixedly installed on the top of the front side of the adsorption tower, and a controller is fixedly installed on the front side of the fixing block.

[0014] Beneficial effects

[0015] The utility model provides a pretreatment device for post-etherification C4 raw materials. Compared with the existing technology, it has the following beneficial effects:

[0016] 1. The controller presets the time to control the air pump to be powered on to absorb the air inside the filter box, and the dust and impurities in the air can be separated through the filter box, and then the air is transported to the inside of the heating box by the air pump, and then the heating wire is powered on to generate high temperature and exchange temperature with the air, so that the air inside the heating box is in a high temperature state, and then the high-temperature air is transported to the inside of the adsorption tower through the one-way valve pipe to exchange temperature with the deoxygenated adsorbent, and then the solenoid valve pipe is powered on to transport the inert gas stored in the storage tank to the inside of the adsorption tower to contact the deoxygenated adsorbent, thereby promoting the desorption of oxygenated compounds adsorbed on the surface of the adsorbent and restoring the activity of the adsorbent, realizing the function of recycling the adsorption material, avoiding the problem of frequent replacement of the adsorption material by the operator, and reducing the material consumption of the deoxygenation of the carbon four raw material after etherification. It not only solves the problem of frequent replacement of adsorption materials in traditional processes, but also achieves the dual goals of economic benefits and environmental protection by reducing material consumption, improving energy efficiency and extending the service life of the adsorption material.

[0017] 2. By connecting the top pipe of the storage box to external equipment, the etherified C4 raw material can be transported to the inside of the fixed box. The porous structure of the nanoporous plate can facilitate the adsorption and separation of trace solid particles contained in the mixed C4 raw material before the etherified C4 raw material enters the etherification reaction, such as catalyst fragments, corrosion products or dust. The water pump is powered on to generate suction to transport the filtered etherified C4 raw material to the inside of the adsorption tower for deoxygenation, realizing the anti-clogging function, avoiding the problem that the particles and solids carried inside the etherified C4 raw material are easy to clog the adsorption tower, and ensuring the stable deoxygenation effect of the etherified C4 raw material.

[0023] 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.

[0024] See also Figure 1-Figure 4 , this utility model provides two technical solutions:

[0025] The first embodiment: A device for pretreating a C4 feedstock after etherification, comprising a base plate 1, an adsorption tower 2 fixedly mounted on one side of the top of the base plate 1, a pre-filtering mechanism 3 fixedly mounted on one side of the adsorption tower 2 for filtering particles and impurities doped in the C4 feedstock after etherification, and an adsorbent resetting mechanism 4 fixedly mounted on the bottom of the other side of the adsorption tower 2;

[0026] The adsorbent resetting mechanism 4 includes a filter box 401, an air pump 402 is fixedly installed on one side of the filter box 401 through a pipe fitting, a heating box 403 is fixedly installed on one side of the air pump 402 through a pipe fitting, a coiled heating wire 404 is equidistantly installed inside the heating box 403, a one-way valve tube 407 fixedly connected to one side of the adsorption tower 2 is fixedly installed on the top of the heating box 403, a storage tank 405 is fixedly installed on one side of the filter box 401, and a solenoid valve tube 406 fixedly connected to the one-way valve tube 407 is fixedly installed on the top of the storage tank 405;

[0027] The pre-filter mechanism 3 includes a storage box 301, a fixing box 302 is fixedly installed on the top of the storage box 301, two sets of bolts 101 are threadedly installed on both sides of the bottom of the bottom plate 1, and nuts are fixedly installed on the top of the bolts 101;

[0028] Multiple sets of metal plates 201 are fixedly installed inside the adsorption tower 2, and the spaces between the multiple sets of metal plates 201 are filled with deoxygenated compound adsorbent 202. A replenishing pipe 5 is fixedly installed on one side of the storage tank 405, and a valve is fixedly installed on one end of the replenishing pipe 5.

[0029] The metal plate 201 provides an installation location for the oxygen-containing compound removal adsorbent 202. The oxygen-containing compound removal adsorbent 202 uses the SQ112 oxygen-containing compound removal adsorbent, which facilitates the subsequent deoxygenation of the post-etherification C4 raw material.

[0030] The bolt 101 and the nut can be used together to firmly install the base plate 1 in the designated installation position, thereby ensuring the stability of the device installation position and preventing the device from tipping over due to external impact.

[0031] After the operator connects the replenishing pipe 5 to the external storage device, the inert gas can be transported to the storage tank 405 for replenishment. The operator can open and close the internal delivery state of the replenishing pipe 5 by rotating the valve.

[0032] The controller 6 controls the air pump 402 to be powered on for a preset time to absorb the air inside the filter box 401, and the dust and impurities in the air can be separated by the filter box 401. The air is then transported to the interior of the heating box 403 by the air pump 402. The heating wire 404 is powered on to generate high temperature and exchange temperature with the air, so that the air inside the heating box 403 is in a high temperature state. The high-temperature air is then transported to the interior of the adsorption tower 2 through the one-way valve pipe 407 to exchange temperature with the deoxygenated compound adsorbent 202.

[0033] By energizing the solenoid valve tube 406, the inert gas stored in the storage tank 405 is transported to the interior of the adsorption tower 2 to contact the oxygen-containing compound removal adsorbent 202, thereby promoting the desorption of oxygen-containing compounds adsorbed on the surface of the adsorbent, restoring the activity of the adsorbent, and realizing the function of recycling the adsorption material. This not only solves the problem of frequent replacement of adsorption materials in traditional processes, but also reduces material consumption, improves energy efficiency and extends the service life of the adsorption material.

[0034] The second embodiment is mainly different from the first embodiment in that: a fixed block is fixedly installed on the top of the front of the adsorption tower 2, and a controller 6 is fixedly installed on the front of the fixed block; two groups of nanoporous plates 303 are fixedly installed inside the fixed box 302, a water pump 304 is fixedly installed at the bottom of the storage box 301, and a delivery pipe 305 fixedly connected to the top of the adsorption tower 2 is fixedly installed on one side of the water pump 304.

[0035] The controller 6 is electrically connected to the internal electrical equipment of the device through a wire, so that the operator can intelligently control the power supply and operation of the internal electrical equipment of the device through the controller 6. The operator can understand the operating status of the internal electrical equipment of the device through the display screen, thereby facilitating the control of the power supply and operation status of the internal electrical equipment of the device according to the use requirements, thereby increasing the intelligent effect of the device.

[0036] By connecting the top pipe of the storage box 301 to external equipment, the etherified C4 raw material can be transported to the interior of the fixed box 302. The porous structure of the nanoporous plate 303 can facilitate the adsorption and separation of trace solid particles contained in the mixed C4 raw material before the etherified C4 raw material enters the etherification reaction, such as catalyst fragments, corrosion products or dust. The water pump 304 is powered on to generate suction to transport the filtered etherified C4 raw material through the delivery pipe 305 to the interior of the adsorption tower 2 for deoxygenation, thereby realizing the anti-clogging function.
