[0041] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0042] In one embodiment of the present invention:

[0043] Please refer to the attached Figure 1 , comprising a filter press unit 1, a reactor 2, and an oil pump unit 3, wherein a feed end of the filter press unit 1 is connected to a discharge end of the reactor 2, a pressurizing unit 5 is provided on a connecting pipe section between the filter press unit 1 and the reactor 2, and a pressure delivery direction of the pressurizing unit 5 has the same end point as the delivery direction of the reactor 2;

[0044] One discharge end of the filter press unit 1 is connected to the oil pump unit 3, and a three-mixing control valve 107 is provided between the filter press unit 1 and the oil pump unit 3;

[0045] The other discharge end of the filter press unit 1 is connected to the waste gas treatment unit 4, and two mixing control valves 108 are provided between the filter press unit 1 and the waste gas treatment unit 4;

[0046] A liquid outlet pipe 307 is provided between the exhaust gas treatment group 4 and the oil pump group 3, and a gas detector 309 is provided inside the oil pump group 3.

[0047] The discharge end of the hydraulic oil pump 301 is provided with an oil delivery pipe 302, one end of the oil delivery pipe 302 is connected with an oil storage barrel 303, and the gas detector 309 is located on the top of the oil storage barrel 303;

[0048] Please refer to Figure 1-6 The filter press unit 1 comprises an oil storage tank 101, and a plurality of filter press plates 102 are stacked and close to each other in an airtight manner inside the oil storage tank 101, and side discharge pipes 105 are provided on both sides of the filter press plates 102;

[0049] The bottom surface of the filter press unit 1 is provided with an oil storage tank 104, and the discharge end of the side discharge pipe 105 is connected to the oil storage tank 104;

[0050] The oil storage tank 104 is located at the bottom peripheral side of the stacked filter press plates 102, the oil storage tank 101 is a closed box, one side of the filter press unit 1 is connected to a mixed solvent discharge pipe 109, one end of the mixed solvent discharge pipe 109 is connected to a separation tank 304, the second mixing control valve 108 is located on the mixed solvent discharge pipe 109 between the filter press unit 1 and the separation tank 304, a gas outlet slot 305 is provided above one side of the separation tank 304, one end of the gas outlet slot 305 is connected to the exhaust gas treatment group 4;

[0051] A liquid outlet groove 306 is provided at the bottom of the separation tank body 304 on one side away from the gas outlet groove 305, and the liquid outlet groove 306 is connected to the liquid outlet pipe 307. A filling guide layer plate 308 is provided inside the separation tank body 304, and the filling guide layer plate 308 includes two arc-surface blocks distributed in the internal cavity of the separation tank body 304. The overall liquid bearing space inside the separation tank body 304 gradually tilts downward from the gas outlet groove 305 side to the liquid outlet groove 306 side.

[0052] When the pressure filtration method is performed to collect and decompose the gaseous organic solvent, the third mixing control valve 107 is controlled to be closed and the second mixing control valve 108 is controlled to be opened. At this time, the oil, liquid and gas enter the separation tank body 304 through the mixed solvent discharge pipe 2 109. The internal space of the separation tank body 304 is divided by the filling guide layer plate 308. The filling guide layer plate 308 can be the original tank body inside the separation tank body 304. Its specific shape and structure do not need to be restricted. The conditions it meets are that the upper part near the end of the liquid outlet groove 306 has a filling guide layer plate 308, and the lower part near the end of the gas outlet groove 305 has a filling guide layer plate 308. The filling guide layer plate 308 serves to limit the flow space of the liquid. Its function is that when the interior of the separation tank body 304 is relatively full, the liquid can automatically block the liquid outlet groove 306, so that the gas will not enter the oil pump group 3 through the liquid outlet pipe 307, so that the gas detector 309 has concentration error monitoring. At the same time, the gas will also have two beneficial effects. One is that, Figure 5 As shown, when the oil and mixed organic gas enter the separation tank body 304, due to the buoyancy of the air, they can directly interact with the internally filled oil, thereby automatically condensing a portion of the mixed gas; secondly, when the interior of the separation tank body 304 is not full, the space can be easily squeezed by the flowing liquid so that the gas is automatically discharged to the side of the gas outlet groove 305, which can reduce the gas from being transported to the oil storage barrel 303 close to the liquid outlet groove 306 and being erroneously detected, and can play a certain role in protecting the normal detection process.

[0053] Please pay attention to Figure 3-6The side of the single filter press plate 102 is provided with a side discharge port 111 connected to the side discharge pipe 105, and the bottom is provided with a bottom discharge port 110 connected to the mixed solvent discharge pipe 109. The mixed solvent discharge pipe 109 is a connecting pipe, and its outer wall surface is in contact with the bottom discharge port 110 and can pass oil. The side discharge pipe 105 is used to directly supply to the oil storage tank 104. The end of the mixed solvent discharge pipe 109 is directly connected to the separation tank 304. The filtering effect and the pressure effect are the same. Only the passage mode is changed. In the process of ordinary filter pressing, the oil enters the oil storage tank 104 for collection through the side discharge pipe 105. The second mixing control valve 108 is closed so that the mixed solvent discharge pipe There is no liquid flow in the second 109, and the balance of the inlet and outlet volumes inside the separation tank 304 is determined by the throughput of the side discharge pipe 105 and the mixed solvent discharge pipe 1 106. When mixed liquid and gaseous organic solvent treatment is required, there is flow in the mixed solvent discharge pipe 109. The side discharge pipe 105 can be opened to balance the pressure inside the filter press plate 102, and can also be closed so that the discharge end is only for the mixed solvent discharge pipe 109 to increase the flow rate of the mixed solvent discharge pipe 109, and several side discharge pipes 105 can be closed separately to balance the internal air pressure of the entire oil storage tank 104. When opened, the raw material source of the mixed solvent discharge pipe 109 is the supply from the oil storage tank 104 and the pressure supply of the bottom discharge port 110 inside the filter press.

[0054] The treatment process of the gaseous organic solvent of the present invention is roughly as follows: it is specifically divided into two processes, the first one is the collection of the separated oil after conventional pressure filtration, which is the existing conventional fixed liquid separation technology, the material is pressed into the filter press by a pressure pump, and when the compressed air is blown into the filter press, the air pressure inside the filter press changes, forcing the mixed material to contact with the inside of the filter press, thereby pressing and splitting, and then blowing out the liquid, so as to obtain a filter cake with a solid content of 60%-80%, and the squeezed liquid solvent flows out through the side discharge pipe 105 on the side of the filter press plate 102 and is collected by the pump body. In this process of the device, since it is an integral pipeline sealed pressure filtration system, an oil storage tank 104 is independently arranged inside the oil storage tank 101, and the actual distribution of the oil storage tank 104 is the surrounding side of the entire oil storage tank 101, Figure 4In order to facilitate the connection between the reaction side discharge pipe and 105, a section of the oil storage tank 104 is cut at an appropriate height. In the figure, the oil storage tank 104 and the oil storage box are both complete cavities, and the oil flows out to the oil storage tank 104 through the side discharge port 111 on the side of the filter plate 102. When the environmental emission requirements are low, a conventional and more economical method is adopted to directly pump the oil inside the oil storage tank 104 through the hydraulic oil pump 301. At this time, the three mixing control valves 107 should be in an open state, and the two mixing control valves 108 should be in a closed state, that is, the oil does not flow to the separation tank body 304 through the mixed solvent discharge pipe 109, but directly enters the oil storage barrel 303 through the oil delivery pipe 302. The detection end of the gas detector 309 extends into the oil storage barrel 303 to monitor the upper floating gaseous space. When it is detected that the organic content of the air in this interval is excessive, the second set of control methods can be adopted at this time. The solution is to change the states of the three mixing control valves 107 and the two mixing control valves 108, and put them in the closed and open states respectively, so that the oil can be pressed out through the bottom discharge port 110 to the mixed solvent discharge pipe 109 to connect to the separation tank body 304 and flow to the separation tank body 304. A channel is opened on the surface of the gas detector 309 to extract the oil inside the separation tank body 304. After passing through the separation tank body 304, the oil flows from one end of the gas outlet slot 305 to one end of the liquid outlet slot 306. The upper gas converges at one end of the gas outlet slot 305 due to the oblique pressure, and enters the waste gas treatment group 4 after solid filtration by the filter 401, and is discharged after purification treatment. The oil flows to the oil storage barrel 303 again through the liquid outlet pipe 307 for collection. In this way, while meeting the pressure filtration needs, the escaping organic gaseous solvent in the pressure filtration process can be collected, and the waste gas generated by it can be continuously purified to meet environmental protection requirements.

[0056] Please pay attention to Figure 1-Figure 3 The oil pump group 3 includes a hydraulic oil pump 301, and the side of the feed end of the hydraulic oil pump 301 is connected to the side of the filter press unit 1 through a pipeline.

[0058] While satisfying the two oil-liquid-gas separation methods of the previous embodiment, the present invention can still maintain a third common method, that is, when the emission requirements are low or no requirements, and the upper detection limit of the gas detector 309 is high, the ordinary hydraulic pump direct extraction method is used as the basic method, and the second gaseous oil detection in the previous embodiment is used as an auxiliary method, that is, by intelligently controlling the opening state of the mixed solvent discharge pipe 109 and the opening state of the exhaust gas treatment group 4 to adapt to the exhaust gas treatment at the limit value. When the detection range of the gas detector 309 is high, the organic free gas inside the oil storage barrel 303 can never reach the gas detector 3 09 detection alarm interval, close the waste gas treatment group 4 and the second mixing control valve 108, when the concentration in the oil storage barrel 303 is in a higher concentration detection range, timely open the second mixing control valve 108 and the separation tank 304, at this time the second mixing control valve 108 and the third mixing control valve 107 are in a co-existing open state, the co-existence state of the closing is determined according to the detection of the gas detector 309 and production needs, the waste gas treatment group 4 is in real-time standby state more economical, when the waste gas treatment group 4 is completely not working, the closed filter press system and pipeline closed transportation can also have an incomparable environmental gas improvement effect than the traditional open type.
