Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The demister for separating and purifying the organic mixed acid shown in fig. 1 mainly comprises a first-stage defoaming component 501, a second-stage defoaming component 502, a third-stage defoaming component 503 and the like which are matched with each other.
The first-stage defoaming assembly 501 comprises a first tank 5011, a feeding hole 5012 formed in the bottom of the first tank 5011 (the feeding hole 5012 is usually communicated with a reboiler and is used for receiving a tower bottom product at a separation position of a reheated product in the reboiler 2, and a small amount of foam, namely, the foam is usually an ion balancing agent, is remained in the tower bottom product), a first return port 5013 formed in the side wall of the first tank 5011 (the first return port 5013 is located in the middle or lower part of the side wall of the first tank 5011), a branch pipe (the other two ends of the branch pipe are respectively communicated with the rectifying tower and the second-stage defoaming assembly 502), and a plurality of baffle plates 5014 fixed on the inner wall of the first tank 5011 and arranged in a staggered manner. In this embodiment, the branch pipes include a main pipe 5 having one end communicating with the top of the first tank 5011, a first branch pipe 51 communicating with the other end of the main pipe 5 for communicating with the rectifying tower, and a second branch pipe 52 communicating with the other end of the main pipe 5 for connecting the secondary defoaming assembly 502 (the main pipe 5 and the first branch pipe 51 may be provided as a single pipe as needed, so that one end of the second branch pipe 52 is connected to the middle of the aforementioned pipe to form a single branch pipe). The two striker plates 5014 are arranged in a downward inclined mode, so that the projection parts of the plurality of striker plates 5014 on the same horizontal plane are overlapped, the effect of blocking materials can be achieved, and the situation that the materials directly rush to a downstream structure due to overlarge pressure and excessive foam is avoided.
The secondary defoaming assembly 502 comprises a second tank 5021 communicated with one end of the branch pipe and horizontally arranged, a second feed back port 5022 arranged at the bottom of the second tank 5021, a first support bracket 5023 obliquely arranged in the second tank 5021 to divide the second tank 5021 into two parts, a plurality of first guide plates 531 arranged between the inner walls of the first support bracket 5023 and the second tank 5021 and facing the branch pipe, and a plurality of partition plates 5024 arranged on the first support bracket 5023 and arranged at intervals. In this embodiment, the connection point of the first support bracket 5023 and the top of the inner wall of the second tank 5021 is closer to the end of the branch pipe than the connection point of the first support bracket 5023 and the bottom of the inner wall of the second tank 5021. Each baffle 5024 is vertically arranged, so that material airflow can be conveyed downstream through gaps between the baffles 5024; each first guide plate 531 is arranged in an inclined manner towards the feeding direction, so that the inclination tendency of the first guide plate 531 is consistent with that of the first support frame 5023, but the inclination degree of the first guide plate 531 is smaller than that of the first support frame 5023, and thus, liquid drops or foams in the material gas flow can flow to the bottom of the second tank 5021 along the first guide plate 531 and flow out through the second feed back opening 5022.
The third-stage foam removing assembly 503 comprises a third tank 5031 which is vertically arranged and has a middle communicated with (usually connected through a pipe) the other end of the second tank 5021, a third feed back port 5030 which is arranged at the bottom of the third tank 5031, a plurality of second guide plates 532 (each second guide plate 532) which are vertically arranged and are arranged in the third tank 5031 through a second support bracket 5032, a filler 5033 which is arranged in the third tank 5031 and is positioned above the plurality of second guide plates 532, and a discharge pipe 5034 which has one end arranged in the third tank 5031 and is positioned above the filler 5033 and the other end extending out of the third tank 5031; thus, the remaining liquid droplets or foams in the material gas flow are adsorbed and collected by the filler 5033, flow to the bottom of the third tank 5031 along the second guide plate 532 and flow out through the third feed back port 5030, and the material gas flow adsorbed by the filler is conveyed downstream through the discharge pipe 5034. Through adopting the one-level to remove the multiple defoaming cooperation of foam subassembly, second grade defoaming subassembly and tertiary defoaming subassembly, can get rid of the foam in the material totally to can guarantee the quality and the purity of the material of carrying downstream. Specifically, the second tank 5021 has a first inlet, the third tank 5031 has a second inlet, and the long side faces the first inlet or the second inlet to face the material gas flow without generating turbulence to the material gas flow.
In the present embodiment, as shown in fig. 2, the first guiding plate 531 and the second guiding plate 532 are independently composed of a first straight plate 5310 and a second straight plate 5320, the first straight plate 5310 and the second straight plate 5320 have a common long side, and an included angle formed therebetween is an acute angle, as shown in fig. 2; the second deflectors 532 are arranged within the third tank 5031 as shown in fig. 3 to ensure that the stream of material is in sufficient contact with the plurality of second deflectors 532 to help ensure the accumulation of droplets or foam from the stream of material.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
