Abstract

The invention discloses a zero-emission reusing device for paper-making wastewater for fireworks paper. An outlet of a wastewater conveying member (1) is communicated with a pulper; a discharge opening of a screening wastewater pool (2) is communicated with the wastewater conveying member; the discharge opening of a sheet forming wastewater pool (3) is communicated with the wastewater conveying member; the discharge opening of a squeezing wastewater pool (4) is communicated with the wastewater conveying member; a first wastewater outlet for providing dilution water (5) to a paper pulp dilution pool is formed in the sheet forming wastewater pool; the first wastewater outlet is formed in the lower part of a side wall of the sheet forming wastewater pool, and is communicated with the lower part of the paper pulp dilution pool; the discharge opening capable of playing a control role in a paper pulp liquid level in the paper pulp dilution pool is formed in the upper part of the other side wall of the sheet forming wastewater pool; a paper pulp sand remover (6) is arranged; and pulping wastewater is communicated with the pulper via the wastewater outlet of the paper pulp sand remover. According to the zero-emission reusing device disclosed by the invention, sand grains in the pulped paper pulp can be effectively removed; the reuse quality of the sand-removing wastewater is improved; and the zero-emission reusing device has the characteristics of being relatively reasonable in structure, practical and the like.

Description

technical field [0001] The invention relates to a zero-discharge recycling device for papermaking wastewater, in particular to a zero-discharge recycling device for papermaking wastewater used in the production of fireworks, firecrackers and leads, etc., from waste paper or raw pulp boards, and is also applicable to the production of corrugated paper and yellow cardboard , kraft paper and other papermaking wastewater for zero discharge reuse. Background technique [0002] Papermaking wastewater for producing fireworks, firecrackers and lead wires by using paper waste or raw pulp board, including pulping wastewater, pulp screening wastewater, paper forming wastewater, paper pressing wastewater, and cleaning wastewater for cleaning felts. [0003] The patent document with the patent number ZL201310030262.8 announces a "zero-discharge recycling device for waste paper or pulp board papermaking wastewater". The pools are connected; there is a pulping waste water pool, and the ou...
