Centrifugal compressor pressure rises as a heat source for the evaporator
The new process of vapor compression heating black liquor concentration converts the steam generated by the evaporator to the heat source required by the evaporator through the centrifugal compressor, and effectively utilizes the heat energy of the heat exchanger system. It not only ensures that the alkali recovery furnace does not need to supplement other auxiliary fuels, but also makes the steam produced by the alkali recovery furnace become the heat source of the entire plant outside the alkali recovery system, thereby greatly reducing the current factory power boiler load. It not only reduces the cost of alkali recovery, but also reduces the production cost of the entire alkali pulping and papermaking process, achieving double benefits of energy saving and environmental protection. Therefore, the new process of vapor compression heating black liquor concentration has a good development prospect. Based on the analysis of the alkali recovery process of wheat straw black liquor, based on the analysis of the existing multi-effect evaporation black liquor concentrated alkali recovery process, a new alkali recovery process for steam compression heating black liquor concentration process was proposed, and two processes were compared. The characteristics and economy. The operation cost of the new alkali recovery process of the steam compression heating black liquor concentration process is very low, and only one year of the alkali recovery process can save the operating cost of about 8.18 million yuan, and the economic benefit is remarkable. Steam Compression Heating Black liquor concentrated alkali recovery new process The steam generated by the evaporator is heated by the centrifugal compressor to be the heat source required by the evaporator, and the heat energy of the heat exchanger system is effectively utilized. It not only ensures that the alkali recovery furnace does not need to supplement other auxiliary fuels, but also makes the steam produced by the alkali recovery furnace become the heat source of the entire plant outside the alkali recovery system, thereby greatly reducing the current power boiler load of the factory, not only reducing the cost of alkali recovery, but also reducing The production cost of the whole alkaline pulping and papermaking process realizes the double benefits of energy saving and environmental protection.
