Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical equipment technology, specifically relating to a gas phase melt recovery system. Background Technology
[0002] In chemical production processes, especially in the molten state, the melt is prone to sublimation, which is then discharged from the system along with the waste gas. This not only leads to product waste but also causes some pollution to the environment.
[0003] The applicant belongs to a large chemical manufacturing enterprise. In order to respond to the national call to achieve energy conservation and emission reduction requirements, and to better meet environmental protection requirements, the applicant has optimized and upgraded its existing production equipment.
[0004] By introducing and installing a gas phase melt recovery device, the applicant was able to successfully recover products entrained in waste gas, which not only met the continuous needs of chemical production but also met the requirements of energy conservation and environmental protection, fully complying with national strategic requirements. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a gas phase melt recovery system, the technical solution of which is as follows:
[0006] A gas phase melt recovery system includes two gas phase melt recovery units, an induced draft fan, and a melt transfer pump. The gas phase melt recovery units are used to recover products.
[0007] The core component of this utility model is a gas phase melt recovery device, which includes a melt recovery tank cooler and a melt recovery tank body. The induced draft fan is connected to the melt recovery tank cooler through a pipeline. The induced draft fan is used to transport materials to the gas phase melt recovery tank cooler for cooling. The melt recovery tank cooler and the melt recovery tank body are connected through a flange. The melt recovery tank body is equipped with a filter and a steam inner coil. The filter is used to filter materials, and the steam inner coil is used for heating. The outside of the melt recovery tank body is equipped with a steam jacket, which is used to heat the melt recovery tank body. The melt recovery tank body is connected to a melt transfer pump through a pipeline.
[0008] Preferably, in order to ensure that the medium does not clog the pipeline during transportation, all pipelines adopt a jacketed pipeline design.
[0009] Compared with existing technologies, this invention has the following advantages: By installing this equipment, the molten material can be recycled to a recovery tank after cooling. When a specified amount is reached, the system is switched off and the process is completed. Steam is then introduced to melt the material. After melting, the material is recycled back into the system via a melt transfer pump. By adding this equipment, waste of molten products can be effectively reduced, achieving energy conservation and environmental protection while also increasing product revenue for the enterprise.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0013] Example 1
[0014] like Figure 1 As shown:
[0015] A gas phase melt recovery system includes two gas phase melt recovery devices, an induced draft fan 6, and a melt transfer pump 7.
[0016] The vapor phase melt recovery device includes a melt recovery tank cooler 1 and a melt recovery tank body 2. The induced draft fan 6 is connected to the melt recovery tank cooler 1 through a pipeline. The melt recovery tank cooler 1 and the melt recovery tank body 2 are connected through a flange. The melt recovery tank body 2 is equipped with a filter 3 and a steam inner coil 4. The outside of the melt recovery tank body 2 is equipped with a steam jacket 5. The melt recovery tank body 2 is connected to a melt transfer pump 7 through a pipeline.
[0017] The pipelines described in this utility model all adopt a jacketed pipe design to achieve the purpose of preventing blockage.
[0018] The working principle of this utility model is as follows: The gaseous melt medium is introduced into the melt recovery cooler 1 by the induced draft fan 6. The gaseous melt is cooled and collected in the gaseous melt recovery tank 2. When the design volume is reached, the system will switch to offline mode, and then steam will be introduced and fed into the gaseous melt recovery tank 2 to process the material. After the material melts, it is recovered into the system by the melt transfer pump 7.
[0019] This invention uses two sets of gas phase melt recovery devices alternately. When the melt recovery cooler 1 is activated, cooling water is used, while steam is not used.
