Heat exchange steam condensed water recovery device for drying tank

Abstract

The invention relates to a heat exchange steam condensed water recovery device for a drying tank, and belongs to the technical field of steam condensed water recovery facilities in the production process of chemical fibers. The heat exchange steam condensed water recovery device for the drying tank comprises a steam recovery pipe, a heat dissipation device, a filtering mechanism, a clean condensedwater pump outlet mechanism and a clean condensed water storage tank, one end of the steam recovery pipe is connected with a jacket steam guiding outlet of the drying tank, a steam trap, a pressure gauge and a pressure release valve are arranged at the other end of the steam recovery pipe, a heat dissipation device steam inlet pipe is arranged on the upper part of the heat dissipation device, a heat dissipation device condensed water guiding outlet pipe is arranged on the lower part of the heat dissipation device, and the position, corresponding to the position between the steam trap and thepressure release valve, of the heat dissipation device steam inlet pipe is connected with the steam recovery pipe and communicates with the steam recovery pipe; the filtering mechanism is arranged ona grade level and is connected with the heat dissipation device condensed water guiding outlet pipe; the clean condensed water pump outlet mechanism is connected between the filtering mechanism and the clean condensed water storage tank; and the clean condensed water storage tank is arranged on the grade level in an oil agent preparation site through a supporting frame. According to the heat exchange steam condensed water recovery device for the drying tank, water resources are saved, and the cleaning effect of condensed water is ensured.

Description

technical field [0001] The invention belongs to the technical field of steam condensed water recovery facilities in the chemical fiber production process, and in particular relates to a drying tank heat exchange steam condensed water recovery device. Background technique [0002] In chemical fiber production enterprises, it is necessary to dry raw materials such as PTA, DMT, PET (usually in the form of particles), specifically: introduce the aforementioned raw materials into the rotary drying tank, and introduce high temperature into the jacket of the drying tank Steam, the high-temperature steam is used to dry the raw materials through the jacket, so that the moisture content of the raw materials can meet the requirements of the spinning process. Since the above-mentioned high-temperature steam is continuous in and out (continuous in and out), the amount of steam consumed is relatively large, and the amount of condensed water produced after the high-temperature steam is coo...

AI Technical Summary

Problems solved by technology

However, there is no suggestion on how to recycle the heat exchange steam condensed water of the drying tank, because the steam used in the drying tank is usually mixed with debris and dirt peeled off from the inner wall of the jacket of the drying tank, so the cleaning of the condensed water
