Problems solved by technology

[0006] The technical deficiencies in the current corn deep processing production process include the following two aspects: First, the waste steam generated during the dehydration and drying process of various corn deep processing intermediate materials is directly discharged or discharged after removing dust particles or intercepted to recover the materials entrained in the steam flow The particles are discharged after discharge, without recycling the heat energy and moisture in the waste steam; secondly, the waste water and waste steam formed after the use of high-temperature water steam as a heating medium is discharged directly or only part of the condensed water is recovered, and there is no high-efficiency recycling of waste water and heat energy, resulting in a great waste of resources

Embodiment 1

[0025] Component 5. Install a connecting pipe and a delivery pump behind the above-mentioned condensed hot water and water vapor separation and storage device, start the delivery pump to transport the condensed hot water and water vapor separation and storage device stored at the bottom of the condensed hot water and introduce it into the steam boiler or Steam generator, the condensed hot water introduced into the steam boiler or steam generator is used as the water source for generating steam, thus realizing the recovery and recycling of condensed hot water.

[0026] Component 1, Component 2, Component 3, Component 4, Component 5 and the tube bundle dryer together form a cyclic cooperative system. When the tube bundle dryer runs for 12 hours, the three types of corn germ, corn fiber and corn gluten After the water vapor evaporated from the material is collected and filtered by the airflow filtration-pumping equipment described in part 1, clean evaporated water vapor is obtaine...

Embodiment 2

[0037] Component 1, Component 2, Component 3, Component 4, Component 5 and the spray hot air drying equipment together form a circulating cooperative system. When the spray hot air drying equipment runs for 12 hours, the corn steep liquor and corn starch milk After the water vapor evaporated from the material is collected and filtered by the airflow filtration-pumping equipment described in part 1, clean evaporated water vapor is obtained, and enters the condensed hot water described in part 2 together with residual water vapor and condensed hot water and water vapor separation and storage device, the condensed hot water and water vapor separation and storage device gradually accumulate a sufficient amount of condensed hot water and water vapor, which exceeds the maximum water level of the condensed hot water and water vapor separation and storage device Automatically overflow into the overflow water storage tank described in component 3, stop the original steam boiler or steam...

Abstract

The invention provides a method for recycling moisture and heat energy in waste water and waste steam in a corn deep processing process. In order to solve the problems of large water and electricity consumption, large amount of discharged waste water and waste steam, great pollution to the environment and the like in the current deep processing process of corn, an innovative key link is found; a set of circulating cooperation system capable of recycling water and heat energy contained in evaporated water vapor, residual water vapor and condensed hot water is established in the dehydration drying link of various materials. And all water and heat energy of water vapor evaporated from materials or water vapor input from the inside and the outside of the system are almost recycled, so that zero emission in the whole process is realized, and the consumption of water resources and energy sources is greatly reduced. On the basis of original equipment, a circulating type recycling system of water and heat energy is formed only by additionally arranging several pieces of equipment, the equipment cost investment is low, continuous operation heating and continuous working abrasion of the equipment are relieved and slowed down, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction in industrial production, and in particular relates to a method for recycling moisture and heat energy in waste water and steam of corn deep processing process. Background technique [0002] Corn is recognized as an excellent crop in the world, because corn not only has the advantages of easy cultivation and management, low production cost and high yield, but also has a wide range of uses. [0003] Corn used to be mainly processed into corn food or animal feed, but the current development trend is that corn is gradually transformed into industrial raw materials, which are further processed or used as fermentation raw materials. The products of corn deep processing are corn starch (including edible starch, pharmaceutical excipient starch), corn syrup, glucose, corn oil, corn gluten meal, corn fiber and corn gluten. Corn deep processing is of great significance in the n...
