Abstract
The invention discloses an acid and acid regeneration unit waste gas residual heat recovery and waste gas processing system and a method. The system comprises a graphite heat exchanger, a graphite heat exchanger water circulating pump, a water tank and a water cooling tower. The water tank is connected with the water cooling tower; a water circulating pump II is simultaneously connected with the water tank and the water cooling tower; a water circulating pump I connected with the graphite heat exchanger is simultaneously connected with the water tank. According to the acid and acid regeneration unit waste gas residual heat recovery and waste gas processing system and the method, the waste gas displacement can be remarkably reduced, a plenty of industrial water can be recovered, a lot of production resources such as natural gas and electric power can be saved, and the system and the method have significance for reducing cost, improving production efficiency, recovering resources such as heat energy, protecting environment, conserving water and the soil and the like, and has a favorable promotion function.
Description
Technical field
The present invention relates to acid regeneration unit waste gas residual heat to reclaim and technical field of waste gas treatment, especially relate to the higher acid regeneration unit waste gas residual heat of a kind of efficiency to reclaim and exhaust treatment system, and reclaim and waste gas processing method based on the acid regeneration unit waste gas residual heat that this system carries out implementing.
Background technology
Environmental protection is the restraining factors of socio-economic development all the time, and sustainable development must be based upon on the basis of environmental protection, and economic development is at the cost of the environment unsustainable.Therefore, the high pollution such as chemical industry, iron and steel industry all have developed all resource reclaim and the technological means of environmental protection, to meet the requirement of sustainable development, and the acid regeneration mode that such as steel industry is more common.
Current, several hundreds of bar acid regeneration units that domestic steel industry uses, most employing regenerates from state-of-the-art spray roasting in the world, but, the method still cannot be avoided discharging a large amount of steam and a small amount of HCI, therefore often overlap unit and have a significant chimney emitting " white cigarette ", delivery temperature 75 DEG C waste heat energy.
The existing procedure of classical classical acid regeneration unit, although carried out regeneration cycle to spent acid to greatest extent, and the connection carrying out regenerating unit and pickling unit uses, its discharge index also meets GB GB28665-2012 requirement, but, along with increase and the increasingly strict and environmental requirement of sternness of production capacity, the resource reclaim mode of current acid regeneration has seemed more single.For this problem, technical from range, should be placed on the sight of dealing with problems on steam that toxic emission goes out, carry out energy recovery, energy-saving and emission-reduction, and then environmental protect better, promotes current organic efficiency.
