Waste heat recovery system for net part of paper machine

Abstract

The invention provides a paper machine net part waste heat recovery system, and relates to the technical field of papermaking, the paper machine net part waste heat recovery system comprises a rack, the bottom of the rack is of a rectangular box-shaped structure with an open top, the top of the rack is provided with a trapezoidal cover body, the top of the trapezoidal cover body is provided with an axial flow fan, and the middle of the rack is rotatably connected with four driving rollers; a pressing roller is arranged at the tops of the two driving rollers in the middle of the rack, the two ends of the pressing roller are rotationally connected into the adjusting blocks, a net-shaped conveying belt is arranged on the outer sides of the driving rollers, and drying supports are arranged at the left end and the right end in the net-shaped conveying belt; the spiral waste heat utilization pipeline is arranged in the driving roller to heat the driving roller, heat is conducted to the net-shaped conveying belt through the driving roller, paper can be better dewatered and dried, the production efficiency of the paper is further improved, and the problems that in the papermaking process, heat is dissipated, paper pulp cannot be rolled to be flat, and the paper quality is poor are solved. And the surface of the paper is uneven.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a waste heat recovery system of a wire part of a paper machine. Background technique [0002] Paper machine is a general term for a complete set of equipment that makes pulp into paper webs, including headbox, wire section, press section, drying section, calender, reeling machine, transmission section and other main engines, steam and water. , vacuum, lubrication, heat recovery and other auxiliary systems, through the waste heat recovery system, a large amount of high-temperature humid air generated during the papermaking process is recycled and reused, which can reduce energy consumption. [0003] However, as far as the existing waste heat recovery system of the wire section of the paper machine is concerned, when the wire section of the paper machine spreads the pulp, the pulp will be dried, and the heat produced during drying cannot be recovered in time, resulting in a pap...

AI Technical Summary

Problems solved by technology

[0003] However, as far as the current waste heat recovery system of the paper machine wire section is concerned, the pulp will be dried when the paper machine wire section spreads the pulp, and the heat generated during drying cannot be recovered in time, resulting in a papermaking environment The temperature is high, and the pulp in the wire part is prone to unevenness during the forming process due to uneven spraying and no extrusion and flattening mechanism.
