Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and specifically relates to a separation device for detecting organic acids. Background Art

[0002] Organic acid refers to some organic compounds with acidity. The most common organic acid is carboxylic acid (R-COOH), which can react with alcohol to form esters. Carboxyl is the functional group of carboxylic acid. Except for formic acid (H-COOH), carboxylic acid can be regarded as a derivative after the hydrogen atom in the hydrocarbon molecule is replaced by carboxyl. It can be represented by the general formula (Ar) R-COOH. Carboxylic acids are widely present in nature in a free state or in the form of salts and esters.

[0003] In order to facilitate the connection of the steam inlet and outlet of the traditional falling film evaporator, they are usually arranged on the side close to the steam generator. This will cause more steam to gather at the end close to the steam inlet and outlet, resulting in uneven temperature inside the tank, thus affecting the use effect of the falling film evaporator.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problem that the traditional falling film evaporator is usually arranged on the side close to the steam generator for the convenience of connecting the steam inlet and outlet, which will cause more steam to gather at the end close to the steam inlet and outlet, thereby causing uneven temperature inside the tank, thereby affecting the use effect of the falling film evaporator, the basic concept of the technical solution adopted by the utility model is:

[0006] A separation device for detecting organic acids, comprising a tank body;

[0007] A support leg is arranged on one side of the tank body, a uniform heating mechanism is arranged inside the tank body, a uniform distribution mechanism is arranged above the uniform heating mechanism, and the uniform heating mechanism includes a fixing plate fixedly connected to the bottom end of the tank body:

[0008] A concave hole is provided at the top of the fixing plate, a motor is fixedly connected to the bottom end of the inner wall of the concave hole, a rotating shaft is fixedly connected to the output end of the motor, a stirring blade is fixedly connected to the outer wall of the rotating shaft away from the motor, a heating pipe is fixedly passed through the top of the fixing plate, a partition is fixedly connected to the inner wall of the tank body, a first connecting hole and a second connecting hole are provided at the top of the partition, the outer wall of the heating pipe passes through the inner wall of the first connecting hole, and an air outlet pipe and an air inlet pipe are connected on the upper and lower sides of the outer wall of the tank body.

[0009] As a preferred embodiment of the utility model, the uniform distribution mechanism includes a material holding frame, the bottom end of the inner wall of the material holding frame is fixedly connected to an oblique block, the outer wall of the material holding frame is provided with a discharge hole, the bottom end of the material holding frame is fixedly connected to the top of the partition, a guide pipe is arranged above the first connecting hole, the top of the guide pipe is fixedly connected to the bottom end of the cover plate at the top of the tank body, the bottom end of the fixed plate is fixedly connected to a holding frame, the bottom end of the holding frame is connected to a liquid phase exhaust pipe, and the outer wall of the holding frame is connected to a gas phase exhaust pipe.

[0010] As a preferred embodiment of the present invention, there are several heating tubes, and the heating tubes are evenly and symmetrically distributed on the left and right sides of the partition.

[0011] As a preferred embodiment of the present invention, the inner wall diameter of the first connecting hole is larger than the outer wall diameter of the heating tube, the number of the partitions is four, and the second connecting holes are one-to-one corresponding to each other.

[0012] As a preferred embodiment of the present invention, there are a plurality of discharge holes, and the discharge holes are evenly and symmetrically distributed on the outer wall of the material containing frame corresponding to the guide tubes.

[0013] As a preferred embodiment of the present invention, the outer wall diameter of the flow guide tube is smaller than the inner wall diameter of the first connecting hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model first connects the air inlet pipe with the external steam generator, then puts the material into the feeding pipe at the top of the tank body, so that the liquid flows into the heating pipe, and the steam enters into the tank body through the air inlet pipe. At the same time, the motor can be started, and its output end will drive the rotating shaft to rotate. When the rotating shaft rotates, it can drive the stirring blade to rotate, so that the steam will flow under the stirring of the stirring blade, and thus evenly fill the inner periphery of the tank body, thereby preventing a large amount of steam from accumulating at the air inlet pipe outlet, resulting in the temperature of the heating pipe close to the air inlet pipe side being too high, and the temperature of the heating pipe away from the air inlet pipe side being too low. Then the steam will flow upward, and in the process of flowing upward, the steam will pass through the first connecting hole, so that a section of the heating pipe passing through the partition can also be heated, thereby further improving the uniformity of heating of the heating pipe, and the remaining steam will flow upward through the second connecting hole to heat the upper end part of the heating pipe, so that the heating pipe can be heated more evenly, thereby minimizing the effect of uneven temperature heating on the separation work.

[0016] In the utility model, liquid is guided to flow in all directions through the oblique blocks, and then flows to the top opening of the heating tube through the discharge holes provided on the outer wall of the material containing frame. When the liquid flows to the opening, since the gap between the guide tube and the heating tube is very small, the liquid at this time will completely cover the top opening of the heating tube along the outer wall of the guide tube. At this time, the liquid will slowly and evenly form a film-like flow downward along the inner wall of the heating tube, thereby preventing the liquid from simply flowing downward along one side of the outer wall of the heating tube, thereby improving the efficiency and quality of the separation work. The liquid phase after heating and separation will be accumulated in the containing frame, and the gas phase will be discharged from the tank body through the gas phase exhaust pipe and collected by the equipment connected to the outside.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] like Figures 1 to 4As shown, a separation device for detecting an organic acid comprises a tank body 1, a supporting leg 2 arranged on one side of the tank body 1, a uniform heating mechanism 31 is arranged inside the tank body 1, a uniform distribution mechanism 32 is arranged above the uniform heating mechanism 31, the uniform heating mechanism 31 comprises a fixing plate 311 fixedly connected to the bottom end of the tank body 1, a concave hole is provided at the top of the fixing plate 311, a motor 312 is fixedly connected to the bottom end of the inner wall of the concave hole, a rotating shaft 313 is fixedly connected to the output end of the motor 312, a stirring blade 314 is fixedly connected to the outer wall of the rotating shaft 313 away from the motor 312, a heating pipe 315 is fixedly penetrated at the top of the fixing plate 311, a partition 316 is fixedly connected to the inner wall of the tank body 1, a first connecting hole 317 and a second connecting hole 318 are provided at the top of the partition 316, the outer wall of the heating pipe 315 penetrates the inner wall of the first connecting hole 317, and an air outlet pipe 319 and an air inlet pipe 3110 are provided on the upper and lower sides of the outer wall of the tank body 1.

[0026] Furthermore, there are a plurality of heating tubes 315 , which are evenly and symmetrically distributed on the left and right sides of the partition 316 , thereby improving the separation efficiency and separation quality of the liquid.

[0027] Furthermore, the inner wall diameter of the first connecting hole 317 is larger than the outer wall diameter of the heating tube 315, there are four partitions 316, and the second connecting holes 318 are one-to-one corresponding to each other, so that the steam at the bottom can heat the heating tube 315 passing through a section of the partition 316 through the first connecting hole 317, thereby further improving the heating uniformity of the heating tube 315 and improving the separation effect.

[0028] The uniform distribution mechanism 32 includes a material holding frame 321, the bottom end of the inner wall of the material holding frame 321 is fixedly connected to an oblique block 322, the outer wall of the material holding frame 321 is provided with a discharge hole 323, the bottom end of the material holding frame 321 is fixedly connected to the top of the partition 316, a guide pipe 324 is arranged above the first connecting hole 317, the top of the guide pipe 324 is fixedly connected to the bottom end of the cover plate at the top of the tank body 1, the bottom end of the fixed plate 311 is fixedly connected to a holding frame 325, the bottom end of the holding frame 325 is connected to a liquid phase exhaust pipe 326, and the outer wall of the holding frame 325 is connected to a gas phase exhaust pipe 327.

[0029] Furthermore, there are several discharge holes 323 , which are evenly and symmetrically distributed on the outer wall of the material holding frame 321 corresponding to the guide tube 324 , so that the liquid can flow directly to the top opening of the heating tube 315 through the discharge holes 323 , and then directly flow into the inner wall of the heating tube 315 .

[0030] Furthermore, the outer wall diameter of the guide tube 324 is smaller than the inner wall diameter of the first connecting hole 317, so that the liquid can only flow through the small gap between the guide tube 324 and the first connecting hole 317, so that the liquid can cover the top opening of the heating tube 315 along the outer wall of the guide tube 324, thereby forming a uniform film flow to the inner wall of the heating tube 315.

[0031] The implementation principle of the separation device for detecting organic acids in this embodiment is as follows: first, the air inlet pipe 3110 is connected to the external steam generator, and then the material is put into the feed pipe at the top of the tank body 1, so that the liquid flows into the heating pipe 315, and the steam is passed into the tank body 1 through the air inlet pipe 3110. At the same time, the motor 312 can be started, and its output end will drive the rotating shaft 313 to rotate. When the rotating shaft 313 rotates, the stirring blade 314 can be driven to rotate, so that the steam will be stirred by the stirring blade 314 and flow, so as to be evenly filled around the inside of the tank body 1, so as to prevent a large amount of steam from accumulating at the outlet of the air inlet pipe 3110, resulting in the near The temperature of the heating tube 315 on the side of the air inlet pipe 3110 is too high, while the temperature of the heating tube 315 on the side away from the air inlet pipe 3110 is too low. Then the steam will flow upward. During the upward flow, the steam will pass through the first connecting hole 317, so that the section of the heating tube 315 passing through the partition 316 can also be heated, thereby further improving the uniformity of heating of the heating tube 315. The remaining steam will flow upward through the second connecting hole 318 to heat the upper end of the heating tube 315. In this way, the heating tube 315 can be heated more evenly, thereby minimizing the effect of uneven temperature heating on the separation work.

[0032] The material is put into the material holding frame 321 through the feed pipe at the top of the tank body 1, and then the liquid is guided to flow around through the oblique block 322, and then flows to the top opening of the heating tube 315 through the discharge hole 323 opened on the outer wall of the material holding frame 321. When the liquid flows to the opening, because the gap between the guide tube 324 and the heating tube 315 is very small, the liquid at this time will completely cover the top opening of the heating tube 315 along the outer wall of the guide tube 324. At this time, the liquid will slowly and evenly form a film-like flow downward along the inner wall of the heating tube 315, thereby preventing the liquid from simply flowing downward along one side of the outer wall of the heating tube 315, thereby improving the efficiency and quality of the separation work. The liquid phase after heating and separation will be accumulated in the holding frame 325, and the gas phase will be discharged from the inside of the tank body 1 through the gas phase exhaust pipe 327, and collected by the equipment connected to the outside.
