Abstract
The invention discloses a device for recycling waste heat during generation of ammonium phosphate. The device is characterized in that a condensing-water tank, a tube type water heater and a cooled-condensing-water tank are arranged below a first effective heat exchanger in sequence; an air input pipe is arranged on one end of the tube type water heater, and a drying fan is connected with the other end of the tube type water heater; the cooled-condensing-water tank is provided with a desalted-water station port; and the drying fan is provided with a hot-air delivery pipe. The steam condensate of the first effective heat exchanger is first delivered to the shell side of the tube type water heater which is arranged on the inlet of the drying fan to exchange heat with the cold air of the shell side of the tube type water heater, then the steam condensate is cooled and delivered to a condensate tank, and the steam condensate is directly delivered to an anion exchanger and recycled, thus the waste heat of the steam condensate is recycled, and the amount of steam used by an air heater which is arranged on the outlet of the drying fan is reduced.
Description
Technical field
The present invention relates to the heat recovery device in a kind of phosphorus ammonium production.
Background technology
Current, China's energy utilization still exists that utilization ratio is low, deficiency in economic performance, subject matter that ecotope pressure is large, and energy-saving and emission-reduction, improve comprehensive utilization of energy rate, are the fundamental ways that solves energy problem of China, in the status of first developing.
Residual heat resources belong to secondary energy, be the product after primary energy source or combustible material conversion, or the heat discharging in process combustion complete heat remaining after a certain technological process.
And the production feature of high temperature, highly energy-consuming has determined that enterprise has abundant residual heat resources in chemical industry, especially phosphorus ammonium production process, reclaim and rationally utilize heat energy in phosphorus ammonium production process, become the important symbol of weighing phosphorus ammonium industrial technology level.
At present, in the time producing monoammonium phosphate product, the most loopback condensate drum of steam condensate of an effect interchanger in concentrating unit, but cause waste because water temperature over-high cannot send anion exchanger direct reuse, therefore, be necessary to improve.
Summary of the invention
Object of the present invention will provide effectively save energy consumption of one exactly, reduces pollutant emission, thereby reduces products production cost, improves productivity effect, realizes the heat recovery device in the phosphorus ammonium production of economic benefit and energy-conserving and environment-protective doulbe-sides' victory
The object of the invention is that adopted following technical scheme realizes: the heat recovery device of a kind of phosphorus ammonium in producing, comprise condensate water pot after an effect interchanger, condensate water pot, shell and tube water heater, cooling, remove Desultwater Station port, drying air fan, hot blast conveying pipe, air input tube, it is characterized in that: under a described effect interchanger, be arranged in order the condensate water pot arranging after condensate water pot, shell and tube water heater, cooling, wherein shell and tube water heater one end is provided with air input tube, and one end connection arranges drying air fan; Condensate water pot after described cooling is provided with Desultwater Station port; Described drying air fan is provided with hot blast conveying pipe.
Advantage of the present invention and beneficial effect are: this technology is first delivered to the steam condensate of an effect interchanger shell side of the shell and tube water heater that is located at drying air fan import, carried out after heat exchange cooling loopback condensate drum again with the freezing air of tube side, directly send anion exchanger to recycle, not only recycle the waste heat of steam condensate, reduced again the airheater steam consumption that is located at drying air fan outlet simultaneously.
