Product Description

The technological transformation project of 150,000 tons/year of natural color pulp is implemented in the industrial zone of the industrial park.

Project status

Extension of the material preparation system (new raw material processing capacity of 596,000 t/a), new pulp workshop (establishment of a production line of 153,000 t/a of natural colored pulp, adoption of intermittent DDS cooking and the sulfate pulping method), new pulp and cardboard workshop (establishment of a production line of 153,000 t/a of pulp and cardboard), new recycling workshop alkalis (installation of an alkali recycling furnace of 750 tds/d of solids treatment), new 15 MW pumped condensate turbine generator, supporting environmental protection treatment installations and certain public installations and auxiliaries.

What is the role of the heat exchanger in the paper pulp cooking process?

Paper pulp cooking in the paper industry refers to the pulping process of placing the papermaking raw materials and cooking liquid into the cooker to remove the non-cellulosic part of the fibrous material by heating at steam.

The black liquor from paper boiling has high calorific value and good flammability, which is an important autogenous energy source in the paper industry. Heat exchangers play an important role in the paper pulp manufacturing process.

JIEMA heat exchanger series products can be used as a series of key energy-saving equipment in the process of black liquor thickening, which is an important measure to improve utilization energy and environmental protection in paper mills.

JIEMA supplied heaters for the project installed in the washing section of the pulp mill, which are used to cool the black liquor containing a small amount of fiber filtered by the pulp washing equipment sent from the cooking dough, and cool it with tap water. , and heat it to produce hot water (recovery of lost thermal energy); and the heat exchanger used for cooking the white liquor (NaoH, Na2S solution), which consists of preheating the pulp using the black liquor (the washing pulp after cooking) and recovering the filtrate. Recycling filtration) preheating pulp raw materials (wood chips, bamboo chips) baking (high temperature, lye impregnation, fiber softening, decomposition) lye required.

In the paper industry, many processes use heat exchange equipment: the pulping process section (cooking, washing, bleaching, water treatment, waste heat recovery, wastewater cooling, etc.) , the alkali recovery process section, the paper process section (drying, waste vapor recovery), boiler auxiliary equipment, sewage treatment, exhaust gas treatment, and even air conditioning, heating, hot water and other systems , we can see the body of the Jetmaster heat exchanger.
