Embodiment Construction

[0014] Below in conjunction with example the present invention will be further described.

[0015] The pulping raw materials after material cutting, dust removal, purification and pretreatment are sent to the multi-functional high-consistency cooking and bleaching integrated pulping equipment through the conveying equipment, and enter through the feeding port 4, and the feeding port is equipped with a pressure-resistant valve. After the end, close the feeding valve, start the multi-functional high-consistency cooking and bleaching integrated pulping equipment, and then the equipment is driven by the power support driver 11 to rotate the rotating support ring 1; the heat source is fed through the heat source nozzle 8 to heat the raw material, and at the same time Medicament nozzle 9 is sent into presoaked medicament, and reaction starts. According to different types of raw materials, the pre-soaking time is slightly different. After pre-soaking for a certain period of time, the...

Abstract

The invention relates to a multifunctional high concentration stewing blanching integral pulp manufacture device. The device is a long strip shape section structure; the two ends are elliptic end covers; one end is axially provided with a feed opening and is provided with a pressure-resistance valve; the other end is axially provided with two pipe joints which are respectively a hot source pipe opening and a liquid medicine pipe opening; the outer edge part of the device is provided with a discharge opening and a pressure-resistance valve; the middle part is provided with a relief valve; the two ends of the device are respectively provided with a temperature auto-control device, a pressure auto-control device and a pH value display device so as to realize real time display when the multifunctional high concentration stewing blanching integral pulp manufacture device is running and automatically control the reaction to be operated in a set range. The multifunctional high concentration stewing blanching integral pulp manufacture device integrates the functions of heating, intenerating, stewing and blanching, thus saving a plurality of device investments, having no washing and dehydration in the middle and having the advantages of remarkable energy saving and water saving.

Description

technical field [0001] The invention relates to a pulping and papermaking equipment, in particular to a multifunctional high-consistency cooking and bleaching integrated pulping equipment. Background technique [0002] At present, pulping mainly includes the processes of material preparation, cooking, washing, screening and bleaching, among which steaming balls or continuous digesters are usually used for cooking. The traditional pulping method has complex procedures, requires a lot of equipment, high operating costs, difficult waste liquid treatment, and serious pollution. Especially for straw pulp pulping enterprises, because straw pulp contains more silicon, the black liquor of straw pulp It is more difficult to deal with. The equipment cost of the general straw pulp black liquor treatment system sometimes accounts for 20-30% of the total investment of the enterprise, so the operation is more difficult. In order to reduce environmental pollution, the state shut down thou...
