Description

Superfine fiber wet-process impregnation line rinsing bath high-pressure net roller rinsing device

Technical Field

The utility model relates to an ultrafine fiber reinforcing PU leather wet process contains soaking line washing device.

Background

The impregnation process is a necessary process for the superfine fiber reinforced PU leather. The function is as follows: PU and DMF (N, N-dimethylformamide) are proportioned according to the requirements of production process, the base cloth to be impregnated is soaked in PU and DMF materials, and the PU and DMF materials are extruded by a plurality of padders to be uniformly fed into the base cloth. Then, DMF is replaced according to the mutual characteristics of PU and water, water and DMF, and PU and DMF. But DMF and water are mutually soluble, and the DMF concentration in the DMF aqueous solution needs to be extruded for many times and diluted by a large amount of water during water washing to meet the qualified requirement.

1. Currently, a conventional impregnation line is equipped with 13 rinsing baths, the first six groups are 3 ton mangers, the last seven groups are 5 ton mangers, and the last manger is 12 ton. The final purpose is achieved by utilizing the principle that the solution is from high concentration to low concentration through repeated liquid pricking and dilution. However, upon exiting the water wash tank, the total nitrogen in the base fabric was measured at 500mg/l, and even somewhat as high as 600-2000mg/l or more. The residual DMF in the base cloth has high concentration, which causes DMF loss and increases the production cost.

2. When the concentration of DMF in the base cloth is too high, the total nitrogen content in the toluene in the reduced water is increased after the base cloth is reduced, and the treatment capacity of the wastewater after toluene recovery to a sewage treatment station is increased. Each weight reduction line needs more than 30 tons of water toluene, and the treatment cost is increased. At present, the sewage treatment cost of 1 ton of 200-ton of 300mg/l total nitrogen is 15 yuan/ton, the cost for treating 1 ton of 500-ton of 1000mg/l total nitrogen is increased by at least more than 1.5 times, and the sewage treatment cost needs more than 120 ten thousand yuan/year in one year according to the calculation of saving 20 yuan/ton.

SUMMERY OF THE UTILITY MODEL
