Abstract
The utility model discloses a low-temperature steam recycling apparatus in the production of monoammonium phosphate. The apparatus comprises a steam-liquid separator (1), a hot water tank (2), a condensate delivery pump (3) and connecting pipelines, wherein the condensate inlet of the steam-liquid separator (1) is connected with the condensate outlet of an I-effect heater (5), the low-temperature steam outlet of the top of the steam-liquid separator (1) is connected with the hot water tank (2) through the pipeline, and the condensate outlet of the bottom of the steam-liquid separator (1) is connected with the condensate delivery pump (3) through the pipeline. The condensate delivery pump (3) is provided with a raw steam pipe (4) and a process water pipe (8). The apparatus changes the situation that a great deal of hot water is used for flushing in order to prevent the blockage of equipment, a flow pipe, a spouting pipe, a nozzle and the like in the production process of monoammonium phosphate by the slurry concentration process, and not only can the affection of the direct discharge of low-temperature steam condensate on the environment be decreased, but also the heat of the low-temperature steam can be used in production, so that energy can be saved.
Description
Technical field
The utility model relates to steam utilization, specifically, relates to the retrieving arrangement of Low Temperature Steam.
Background technology
Adopt " in and slurry concentrated process " produce in the powdery monoammonium phosphate process, slip need concentrate through multiple-effect, and wherein, I is imitated well heater and used primary steam heating, and after steam and the heat exchange of I effect slip, phlegma directly discharges.The discharging the vapor condensation liquid temp generally up to 100 ℃～125 ℃.This phlegma directly discharges, and has both wasted a large amount of heats, causes energy dissipation, influences environment again.
By retrieval, the application part that relates to the Low Temperature Steam utilization in Chinese patent literature has: No. 97125913 " utilizing the trade effluent electrolytic processing apparatus of steam/exhaust steam ", No. 200610025761 " cast-in-place box girder low-temperature steam maintenance operating method ", No. 200810189764 " low temperature steam engine and internal combustion engine double dynamical vehicle or watercraft ", No. 200910077031 " a kind of process for low-temperature steam drying efficiently " etc.But these patented technologies are all irrelevant with the production of monoammonium phosphate.
Summary of the invention
The purpose of this utility model is to provide the recycle device of Low Temperature Steam in a kind of monoammonium phosphate production, utilizes once more to realize steam condensate, and directly discharging is to the influence of environment both to have changed it, and partly heat is used for production, save energy again.
The recycle device of Low Temperature Steam during the monoammonium phosphate that the designer provides is produced, form by vapour liquid separator, hot water tank, phlegma transferpump and connecting tube, wherein, the phlegma import of vapour liquid separator is connected with the condensate outlet that I is imitated well heater, the Low Temperature Steam outlet at its top is connected with hot water tank by pipeline, and the condensation-water drain of its bottom is connected with the phlegma transferpump by pipeline.
Above-mentioned hot water tank is furnished with a primary vapour pipe, and supply system keeps closing condition at ordinary times with primary steam when the start-stop car; Is furnished with the technology water pipe in addition.
Above-mentioned hot water tank uses plain carbon stool plate or stainless steel plate to make.
The using method of the recycle device of Low Temperature Steam is in the monoammonium phosphate production: after I effect steam condensate is carried out the carbonated drink separation by vapour liquid separator, about 100 ℃～125 ℃ Low Temperature Steam is carried a spot of hot water secretly and is introduced the heating source of hot water tank as hot water with pipeline, and isolated water of condensation uses as recirculated water after the desalination water station is handled by being pumped into.
The recycle device of Low Temperature Steam during monoammonium phosphate of the present utility model is produced, changed in the production process of slurry concentration process monoammonium phosphate, stop up in order to prevent positions such as equipment, charge tube, shotcrete pipe, nozzle, the situation of using a large amount of hot water to wash, can reduce the influence of the direct discharging of Low Temperature Steam water of condensation to environment, its heat can be used for again producing save energy.
Description of drawings
Fig. 1 is the structural representation (being device of the present utility model in the dotted line) of the recycle device of Low Temperature Steam during monoammonium phosphate of the present utility model is produced.
1 is vapour liquid separator among the figure, and 2 is hot water tank, and 3 is the phlegma transferpump, and 4 is primary vapour pipe, and 5 are I effect well heater, and 6 is vaporizer, and 7 is recycle pump, and 8 is the technology water pipe.
Embodiment
Urn good fortune phosphate fertilizer plant of Wengfu Group Co., Ltd. powdery monoammonium phosphate production line uses the recycle device as Low Temperature Steam in the monoammonium phosphate production of accompanying drawing 1, it is made up of vapour liquid separator 1, hot water tank 2, phlegma transferpump 3 and connecting tube, wherein, the phlegma import of vapour liquid separator 1 is connected with the condensate outlet that I is imitated well heater 5, the Low Temperature Steam outlet at its top is connected with hot water tank 2 by pipeline, and the condensation-water drain of its bottom is connected with phlegma transferpump 3 by pipeline.Hot water tank 2 is furnished with a primary vapour pipe 4 and technology water pipe 8.
After coming into operation, per hour save 5.0 tons of steam, calculate 300 days working times per year, consume steam, can only save ten thousand yuan of steam consumption expenses=300 * 24 * 5.0 * 30=108 every year by 30 yuan of/ton accounting of the said firm's inside price.
Claims (2)
1. the recycle device of Low Temperature Steam during a monoammonium phosphate is produced, it is made up of vapour liquid separator (1), hot water tank (2), phlegma transferpump (3) and connecting tube, wherein, the phlegma import of vapour liquid separator (1) is connected with the condensate outlet that I is imitated well heater (5), the Low Temperature Steam outlet at its top is connected with hot water tank (2) by pipeline, and the condensation-water drain of its bottom is connected with phlegma transferpump (3) by pipeline.
