Decolorizing treatment system for paulownia wood

Abstract

The invention discloses a decolorizing treatment device for paulownia wood. The decolorizing treatment system is characterized in that a water-cycling system is formed by a soaking treatment pool, a sewage pool communicated with the soaking treatment pool and a purifying pool communicated with the sewage pool, wherein a heat exchanger communicated with a solar heater is arranged in the soaking treatment pool, and the soaking treatment pool is communicated with the purifying pool through a water feed pipe; the water feed pipe is connected with a pump body for pumping water in the purifying pool into the soaking treatment pool; the sewage pool is communicated with the purifying pool through a purifying pipe; the wall of the soaking treatment pool is an interlayer wall with a thermal insulation layer; and solar hot water is pumped to the heat exchanger through the pump body connected to a solar water pipe, and heat of the hot water is radiated to the soaking treatment pool through the heat exchanger. According to the decolorizing treatment system, solar heating is utilized, therefore, the decolorizing treatment system has the advantages of energy saving, environmental protection, fuel saving, simple structure and convenience for operation; the decolorizing time of the paulownia wood is short, soaking treatment can be finished in seven days or even a shorter period of time, the effect is good, and the working efficiency is high; and an ideal decolorizing effect can be guaranteed, and energy and emission can be reduced so as to avoid environmental pollution.

Description

technical field [0001] The invention relates to a wood water treatment facility, in particular to a Paulownia wood decolorization treatment system for treating Paulownia wood. Background technique [0002] Wood color is not only an important characteristic of the visual physical quantity of wood surface, but also an important index to evaluate the quality of wood and determine the commodity value of wood products, which is of great significance to the processing and utilization of wood. Wood color is also an important indicator of short-period fast-growing plantation timber, and its chromaticity index is directly related to the apparent quality of wood, and affects the use value and utilization rate of wood. Wood discoloration has always troubled wood processing enterprises and users, and people try to get rid of the color of discolored wood. [0003] Paulownia wood is an important industrial material in my country. It is widely used in the production of interior building ...
