Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to an efficient condenser for chemical intermediates. Background Technique

[0002] Chemical intermediates are important raw materials for the production of fine chemical products such as chemical pharmaceuticals, pesticides, dyes, pigments, rubber and plastic auxiliaries, essence, spices, and electronic chemicals. They are an important foundation for the production of fine chemical products. The rapid development of the global fine chemical industry has driven the growth of the demand for the global chemical intermediate industry and the progress of production technology. In the production process of chemical intermediates, in order to extract the required raw materials, it is also necessary to use a condenser to condense the steam generated during the production of chemical intermediates.

[0003] After retrieval, the publication number is CN220602243U, which discloses an efficient condenser for chemical intermediates. The steam generated during the production of chemical intermediates is introduced into the steam tank through a steam pipe, and the cold air is introduced into the cold air tank through a cold air pipe. Under the heat conduction of a spiral plate made of aluminum alloy heat-conducting material, the steam generated during the production of chemical intermediates exchanges heat with the cold air. The partition plate is used to separate the spaces inside the steam tank and the cold air tank, increasing the heat exchange area between the cold air and the steam generated during the production of chemical intermediates, and condensing some substances in the steam generated during the production of chemical intermediates into liquid.

[0004] In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. The above case only condenses through the cold air in the cold air pipe. When the steam generated during the production of chemical intermediates has a relatively fast flow rate, the time passing through the shell is short, affecting the condensation effect of the steam.

[0005] Therefore, we propose an efficient condenser for chemical intermediates that can solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide an efficient condenser for chemical intermediates, which solves the problems raised in the background technique.

[0007] To achieve the above object, the utility model provides the following technical solutions: An efficient condenser for chemical intermediates, comprising a condensation cylinder, wherein the middle parts of both sides of the condensation cylinder are respectively penetrated and fixedly installed with an air inlet pipe and an air outlet pipe; a buffer mechanism: used to slow down the flow rate of steam, the buffer mechanism includes a heat exchange pipe, and heat exchange plates are vertically and fixedly installed on the outer side of the heat exchange pipe. First connection grooves and second connection grooves are respectively opened in the middle parts of the top end and the bottom end of the condensation cylinder, and both ends of the heat exchange pipe are rotatably connected to the first connection groove and the second connection groove respectively through sealing bearings; a condensation mechanism: used for condensing steam, the condensation mechanism includes a condensation groove, the condensation groove is vertically opened inside the heat exchange plate, and the condensation groove is communicated with the heat exchange pipe. The first connection groove is communicated with the second connection groove through the heat exchange pipe. Liquid inlet pipes and liquid outlet pipes are respectively fixedly installed in the middle parts of the upper surface and the lower surface of the condensation cylinder, and an annular collection groove is opened outside the second connection groove.

[0008] As an alternative embodiment of the technical solution of the present application, the heat exchange plates are uniformly distributed on the outer side of the heat exchange pipe, and the size of the heat exchange plates matches that of the condensation cylinder.

[0009] As an alternative embodiment of the technical solution of the present application, collection holes are uniformly opened on the inner wall of the bottom end of the condensation cylinder, and the condensation cylinder is communicated with the collection groove through the collection holes.

[0010] As an alternative embodiment of the technical solution of the present application, a drain pipe is fixedly installed at the bottom end of one side of the condensation cylinder, and the liquid inlet end of the drain pipe is communicated with the bottom end inside the condensation cylinder.

[0011] As an alternative embodiment of the technical solution of the present application, liquid guide grooves are vertically penetrated on the outer side of the heat exchange plate, and the liquid guide grooves are uniformly distributed on the front and back sides of the heat exchange plate.

[0012] As an alternative embodiment of the technical solution of the present application, the liquid outlet end of the liquid inlet pipe is communicated with the first connection groove, and the liquid inlet end of the liquid outlet pipe is communicated with the second connection groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows. The steam generated in the production of chemical intermediates is discharged through the air outlet pipe. When the steam flow rate is relatively high, it can drive the heat exchange plates on the outer side of the heat exchange pipe to rotate, thereby reducing the steam flow rate and avoiding the influence of too fast steam flow rate on the condensation effect. Through the communication between the heat exchange pipe and the condensation groove inside the heat exchange plate, cold water is introduced into the heat exchange pipe and the heat exchange groove through the first connection groove communicated with the liquid inlet pipe. The further low-temperature heat exchange plates can exchange heat with the steam generated in the production of chemical intermediates, so that the steam is condensed into liquid, and is collected through the liquid guide grooves, collection holes, collection grooves and drain pipes.

[0019] In this technical solution, the steam generated in the production of chemical intermediates is discharged into the condensation cylinder 1 through the outlet pipe 12. Since both ends of the heat exchange tube 13 are rotatably connected to the first connection groove 16 and the second connection groove 17 through sealed bearings, when the steam flow rate is high, it can push the heat exchange plate 14 on the outer side of the heat exchange tube 13 to rotate, thereby reducing the steam flow rate and avoiding the influence of too fast steam flow rate on the condensation effect.

Further, the lower-temperature heat exchange plate 14 and heat exchange tube 13 can exchange heat with the steam generated in the production of chemical intermediates, causing the steam to condense into a liquid. A plurality of heat exchange plates 14 are fixedly installed on the outer side of the heat exchange tube 13.
