Concentrated niter discharge hot water recycling system

Abstract

The invention discloses a concentrated niter discharge hot water recycling system, and belongs to the technical field of design of chemical engineering equipment. The concentrated niter discharge hot water recycling system comprises a water treater, a lower inlet, a water return port, a cooler, an upper water inlet, a water outlet, a cold desalted water tank and a water tank; the water treater is communicated with a lower water inlet in the bottom of the cooler; hot desalted water flowing out from the water treater enters the cooler from the lower water inlet; the water outlet is formed in the left side of the cooler; the hot desalted water flows out from the water outlet to enter the cold desalted water tank for future use after being cooled by the cooler; and an upper water inlet formed in the top of the cooler is communicated with the water return port of the cooler. The concentrated niter discharge hot water recycling system is large in cooling area and fast in cooling; and the water treater, the cold desalted water tank and the water tank are waste equipment replaced from diluted niter, so that the maintenance cost and the operation cost are not needed, and the economic benefit is excellent.

Description

Technical field [0001] The invention relates to the technical field of chemical equipment design, in particular to a system for recycling hot water discharged from a concentrated nitrate device. Background technique [0002] A large amount of heat is generated when the concentrated nitrate plant is produced. The hot water returned from the concentrated nitrate expansion tank to the water treatment hot water tank is only rarely used for the synthesis of ammonia, and a lot of the remaining heat is directly discharged, causing greater economic losses At the same time, it also adds a lot of additional burdens to the protection of the environment. How to make full use of this heat and reduce environmental pollution has always been a problem that the company’s technical personnel are working hard on. The present invention will add to the 80℃ hot water pipeline sent from the power workshop. A spiral plate heat exchanger uses circulating water and hot water to exchange heat and drop the ...
