Abstract
Description
Technical Field
[0001] This utility model relates to the field of diphenyl ethane production technology, specifically to a condensation and recovery device for diphenyl ethane production. Background Technology
[0002] Diphenyl ethane is an important intermediate in the preparation of existing fuels and pharmaceuticals. Its industrial production uses benzene as a raw material. Since the reaction is exothermic, the waste gas produced contains a large amount of gaseous benzene. Conventional tail gas treatment in factories cannot treat it in an environmentally friendly manner. Furthermore, the removal of gaseous benzene reduces the amount of benzene participating in the reaction, leading to the generation of a large number of by-products. This is not conducive to the stable control of the reaction, resulting in serious waste of benzene raw materials and high production costs for diphenyl ethane.
[0003] Therefore, it is necessary to provide a condensation recovery device for diphenyl ethane production to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a condensation and recovery device for diphenyl ethane production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A condensation recovery device for diphenyl ethane production includes a tank body, on the surface of which a first pipe and a second pipe are respectively installed. A condensation container is disposed inside the tank body, and a discharge pipe is installed at the bottom of the condensation container. A valve is installed at the end of the discharge pipe away from the condensation container. A main heat dissipation column is also installed on the surface of the condensation container, and a secondary heat dissipation column is installed at the end of the main heat dissipation column away from the condensation container. An inlet pipe and an outlet pipe are respectively installed on the surface of the condensation container. A cover is installed at the opening of the tank body, and both the inlet pipe and the outlet pipe are connected through the cover.
[0007] Preferably, the condensate container and the discharge pipe are designed as an integral unit, and the discharge pipe and the tank body are connected by a through weld.
[0008] Preferably, the condenser is threadedly fitted with a cover.
[0009] Preferably, the main heat dissipation columns are evenly distributed on the surface of the condensation container, and the secondary heat dissipation columns are distributed at equal angles on the main heat dissipation columns.
[0010] Preferably, both the intake pipe and the exhaust pipe are made of metal, and the lower ends of both the intake pipe and the exhaust pipe have a spiral structure.
[0011] Preferably, the intake pipe and exhaust pipe are welded to the condenser container.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Waste gas containing gaseous benzene is introduced into the condensation container through the inlet pipe and then discharged through the exhaust pipe. During this process, condensate is continuously injected into the tank through the first pipe until it submerges the condensation container, the inlet pipe, and the exhaust pipe. The condensate cools the waste gas flowing through the inlet pipe, the condensation container, and the exhaust pipe. At the same time, the main heat dissipation column and the secondary heat dissipation column on the surface of the condensation container increase the contact area between the condensation container and the condensate, thereby improving the condensation effect of the waste gas in the condensation container. This facilitates the condensation of gaseous benzene before centralized collection and recovery. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 One embodiment provided by this utility model:
[0024] A condensation recovery device for diphenyl ethane production includes a tank 1, with a first pipe 2 and a second pipe 3 respectively installed on the surface of the tank 1. A condensation container 4 is disposed inside the tank 1, with a discharge pipe 5 installed at the bottom of the condensation container 4. A valve 6 is installed at the end of the discharge pipe 5 away from the condensation container 4. A main heat dissipation column 8 is also installed on the surface of the condensation container 4, with a secondary heat dissipation column 9 installed at the end of the main heat dissipation column 8 away from the condensation container 4. An inlet pipe 10 and an exhaust pipe 11 are respectively installed on the surface of the condensation container 4. A cover 12 is installed at the opening of the tank 1, and both the inlet pipe 10 and the exhaust pipe 11 are connected through the cover 12.
[0025] In one embodiment, the condenser 4 and the discharge pipe 5 are designed as a single unit, and the discharge pipe 5 is welded through the tank body 1, which facilitates the stable installation of the condenser 4 into the tank body 1 through the discharge pipe 5.
[0026] In one preferred embodiment, a cover 7 is threaded onto the condenser container 4, which facilitates the periodic removal of the cover 7 to clean the inner wall of the condenser container 4.
[0027] In one embodiment, the main heat dissipation column 8 is evenly distributed on the surface of the condensation container 4, and the auxiliary heat dissipation column 9 is distributed at equal angles on the main heat dissipation column 8, which improves the uniformity of the distribution and installation of the main heat dissipation column 8 and the auxiliary heat dissipation column 9, and facilitates the rapid removal of heat from the condensation container 4 by the main heat dissipation column 8 and the auxiliary heat dissipation column 9.
[0028] In one preferred embodiment, both the intake pipe 10 and the exhaust pipe 11 are made of metal, and the lower ends of both the intake pipe 10 and the exhaust pipe 11 have a spiral structure, which can extend the travel path of the gaseous benzene waste gas, thereby facilitating its condensation and cooling.
[0029] In one preferred embodiment, the intake pipe 10 and the exhaust pipe 11 are welded to the condenser container 4, which improves the stability of the installation of the intake pipe 10 and the exhaust pipe 11 and prevents breakage and tilting.
[0030] The working principle of this utility model is as follows: the cap 12 is placed on the tank body 1, and then the external condensate is injected into the tank body 1 through the first pipe 2 until the condensate level exceeds the spiral part of the air inlet pipe 10 and the exhaust pipe 11. Then the waste gas containing gaseous benzene is injected into the air inlet pipe 10. At this time, the waste gas containing gaseous benzene is injected into the condensation container 4 through the air inlet pipe 10, and then discharged from the condensation container 4 through the exhaust pipe 11.
[0031] During this process, the gaseous benzene waste gas will be cooled and condensed by the condensate in the tank 1. In particular, when the waste gas enters the condensation container 4, the main heat dissipation column 8 and the secondary heat dissipation column 9 on the surface of the condensation container 4 will improve the condensation effect of the condensation container 4 and accelerate the condensation of the gaseous benzene in the waste gas. The condensed gaseous benzene will be collected in the condensation container 4, and the remaining waste gas will be discharged through the exhaust pipe 11.
[0032] As condensate is continuously injected into tank 1 through the first pipe 2, the heated condensate is also continuously discharged through the second pipe 3, thereby continuously maintaining the low temperature environment inside tank 1.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
