TECHNICAL FIELD

[0001] The utility model relates to methanol removal technical field, concretely is a methanol removal equipment. BACKGROUND

[0002] In some energy chemical production processes, methanol is produced as by-product. For example, in the process of coal gasification to make synthetic gas, in addition to generating the main product synthetic gas (carbon monoxide and hydrogen), a small amount of methanol will also be produced. This is because a series of complex chemical reactions will occur in the coal gasification process, and under certain conditions, carbon, hydrogen, oxygen and other elements will combine to form methanol. The methanol in these gases needs to be removed to improve the quality of synthetic gas.

[0003] The existing methanol removal device uses an adsorption layer with added adsorbent to remove methanol in the gas, but as the adsorption process proceeds, the active sites on the surface of the adsorbent are gradually occupied by methanol molecules, and when the adsorbent reaches saturation, its adsorption capacity will decrease significantly. The existing methanol removal device is not convenient for regular replacement of the adsorption layer, thereby affecting the adsorption effect. SUMMARY

[0037] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0038] Embodiment one

[0039] Reference Figures 1-5The utility model provides a methanol removal equipment, including main part assembly 1, the main part assembly 1 includes: removal cavity 11, the outer side wall fixedly connected with outer frame 12, adsorption layer 13 is arranged in the recess of removal cavity 11 with the outer frame 12, the outer frame 12 with adsorption layer 13 is provided with replacement assembly 2, replacement assembly 2 includes: connecting plate 21, fixedly connected in adsorption layer 13 top, fixed rod 22, is fixedly connected to the outer side wall of connecting plate 21 symmetry, limit slot 221, is symmetrically set up in fixed rod 22, frame 23, is fixedly connected to the top of outer frame 12 symmetry, cavity 231, is set up in the inside wall of frame 23, spring 24, is fixedly connected to the inside wall of cavity 231 symmetry, limit rod 25, is fixedly connected to the end of spring 24 away from the inside wall of cavity 231, pull rod 26, is fixedly connected to the outer side wall of limit rod 25 symmetry, and the end of pull rod 26 away from limit rod 25 is penetrated and extends to the outside of frame 23, pull plate 27, is fixedly connected to the end of pull rod 26 located the outside of frame 23, and the bottom end edge of connecting plate 21 is provided with sealing pad 4, and the inside wall of cavity 231 is symmetrically provided with sliding groove 251, and the both ends of limit rod 25 extend and slide in sliding groove 251.

[0040] In use, removal cavity 11 left end connects the air inlet pipe, right end connects the air outlet pipe, with the gas of methanol entering the inside of removal cavity 11, when passing through adsorption layer 13, because adsorbent has huge specific surface area and rich pore structure, methanol molecules are adsorbed on the surface of adsorbent under the action of van der waals force or chemical bond, thereby realizing the separation of methanol and gas, and the gas after removing methanol is discharged through the right end of outer frame 12, when adsorption layer 13 needs to be replaced, staff first pull the pull plate 27 on both sides to the outside, and the pull plate 27 drives the pull rod 26 to move to the outside, and the pull rod 26 drives the limit rod 25 to be separated from the limit slot 221, at this time, the connecting plate 21 is lifted to realize the disassembly of adsorption layer 13, and the staff regenerates the adsorbent on adsorption layer 13 by using heating desorption or pressure reduction desorption, or directly replaces new adsorption layer 13, to avoid affecting the normal filtration of gas.

[0041] When the adsorption layer 13 is installed, the staff also need to pull the pull plate 27 outward, the limiting rod 25 extrudes the spring 24, at this time the adsorption layer 13 is inserted into the removal cavity 11 and the groove of the outer frame 12, at this time the fixing rod 22 enters the cavity 231, the pull plate 27 is loosened, the spring 24 pops the limiting rod 25 into the limiting groove 221, the limiting of the fixing rod 22 is realized, so that the replacement of the adsorption layer 13 is completed, which is more convenient. When the adsorption layer 13 is installed, the sealing gasket 4 at the bottom edge of the connecting plate 21 contacts the edge of the groove on the removal cavity 11 and the outer frame 12, so that the sealing of the connecting part is realized, the leakage of gas during the removal of methanol is avoided, and the safety hidden danger is caused. When the limiting rod 25 is affected by the frame 23 and the pull rod 26 and moves, the limiting rod 25 slides at both ends in the sliding groove 251, the sliding groove 251 guides the movement of the limiting rod 25, so that the stability of the limiting rod 25 when moving is improved, and the limiting of the fixing rod 22 is quickly realized or released.

[0042] The components of the adsorption layer 13 can include activated carbon, molecular sieve, metal oxide and polymer adsorbent, etc., and the included components can be changed according to different gases, as long as the removal of methanol in the gas can be realized.

[0043] Example two

[0044] According to the basis of example one, an auxiliary function is added.

[0045] Referring to Figures 1-5 The bottom end of the fixing rod 22 has an inclined surface. The top of the connecting plate 21 is symmetrically and fixedly connected with a handle 3. The outer frame 12 is provided with a gas chromatograph 5 on the outer side wall, and the sampling probes at both ends of the gas chromatograph 5 are respectively inserted into the inside of the removal cavity 11, and the two sampling probes are respectively located on both sides of the adsorption layer 13.

[0046] The slope on the fixed rod 22 enables the installation of the adsorption layer 13 without the staff pulling the pull plate 27 in advance: the staff directly inserts the adsorption layer 13 into the removal cavity 11 and the groove of the outer frame 12, at this time, the fixed rod 22 on both sides is inserted into the cavity 231, the slope at the bottom of the fixed rod 22 pushes the limiting rod 25 to the spring 24 direction when passing through the limiting rod 25, causing the compression of the spring 24, when the bottom of the adsorption layer 13 contacts with the inner bottom surface of the removal cavity 11, at this time, the limiting rod 25 and the limiting groove 221 are located on the same horizontal line, the spring 24 automatically pops the limiting rod 25 into the limiting groove 221, thereby limiting the fixed rod 22, increasing the convenience of the staff when replacing the adsorption layer 13. The handle 3 at the top of the connecting plate 21 improves the comfort and convenience of the staff's hands when installing or dismounting the adsorption layer 13. In the process of removing the gas methanol, two sampling probes of the gas chromatograph 5 collect the untreated and adsorbed gas samples of the adsorption layer 13 into the sample system of the gas chromatograph 5, the sample system quantitatively injects the collected gas samples into the chromatographic column, the adsorption and desorption capacity of methanol and other gases on the stationary phase is different, and they will flow out of the chromatographic column at different times. The detector converts the gas components into an electrical signal, and the size of the signal is proportional to the concentration of the gas. The electrical signal is transmitted to the data processing system, which is processed and analyzed by the dedicated chromatographic analysis software. The software converts the electrical signal into the concentration value of methanol and other gas components according to the preset standard curve, and displays and records the data in real time. The staff can view the real-time analysis results through the data processing system to understand the change of the methanol concentration in the inlet and outlet gas of the adsorption layer 13, thereby observing the state of the adsorption layer 13 and replacing the adsorption layer 13 in time.
