Abstract
The utility model provides a sulphuric acid refrigerated device, heat transfer system includes desalinized water passageway and sulphuric acid passageway, absorption tower bottom be equipped with behind the sulphuric acid passageway that the pipeline passed heat transfer system with the circulating slot intercommunication, be equipped with dense acid circulating pump in the circulating slot, dense acid circulating pump output and heat exchanger sulphuric acid entrance point intercommunication, heat exchanger include circulating water channel, the sulphuric acid exit end of heat exchanger and the sulphuric acid entry end on absorption tower intercommunication, pipeline between absorption tower bottom and the heat transfer system is the cast iron pipeline, the heat exchanger is plate heat exchanger. The utility model discloses simple structure, function practicality utilize the desalinized water to pass through stainless steel heat transfer system cooling sulphuric acid temperature, and the recovery waste heat reduces the circulation water yield, has practiced thrift manufacturing cost.
Description
Technical field
This utility model relates to the device of a kind of sulphuric acid cooling.
Background technology
At present, the sulphuric acid after sulfur trioxide that absorbs flowed out bottom absorption tower is flowed into circulating slot, and sulphuric acid temperature is increased to 85 DEG C, enters absorption towers continue cycling through suction sulfur trioxide cooling 65 DEG C through heat exchange.Need substantial amounts of cooling water to cause waste to reduce the temperature of sulphuric acid, heat energy and water, too increase production cost.
Utility model content
This utility model provides the device of a kind of sulphuric acid cooling, recovery waste heat, reduces quantity of circulating water, has saved production cost.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that the device that a kind of sulphuric acid cools down, heat-exchange system includes desalted water passage and sulphuric acid passage, it is provided with pipeline bottom absorption tower to connect with circulating slot after the sulphuric acid passage of heat-exchange system, concentrated acid circulating pump it is provided with in circulating slot, concentrated acid circulating pump outfan connects with heat exchanger sulphuric acid entrance point, and heat exchanger includes circulating water channel, and the sulphuric acid port of export of heat exchanger connects with the sulphuric acid arrival end on absorption tower.
Pipeline bottom absorption tower and between heat-exchange system is cast-iron pipe.
Described heat exchanger is plate type heat exchanger.
This utility model simple in construction, practical function, utilize desalted water to pass through rustless steel heat-exchange system cooling sulphuric acid temperature, recovery waste heat, reduce quantity of circulating water, saved production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment: as shown in Figure 1, a kind of device of sulphuric acid cooling, heat-exchange system includes desalted water passage and sulphuric acid passage, it is provided with pipeline bottom absorption tower 1 to connect with circulating slot 2 after the sulphuric acid passage of heat-exchange system, concentrated acid circulating pump 4 it is provided with in circulating slot 2, concentrated acid circulating pump 4 outfan connects with heat exchanger sulphuric acid entrance point, and heat exchanger includes circulating water channel, and the sulphuric acid port of export of heat exchanger connects with the sulphuric acid arrival end on absorption tower 1.Pipeline bottom absorption tower 1 and between heat-exchange system 3 is cast-iron pipe.Heat exchanger is plate type heat exchanger 5.
Sulphuric acid 8 after the absorption sulfur trioxide flowed out bottom absorption tower 1 carries out heat exchange through cast-iron pipe to rustless steel heat-exchange system 3 and the desalted water 6 come from water process, sulphuric acid is flowed into circulating slot 2 after being cooled down, sulphuric acid temperature is dropped to 75 DEG C by 85 DEG C, desalted water 6 temperature is increased to 80 DEG C by 25 DEG C and sends in boiler feeds, and concentrated sulphuric acid pumps into plate type heat exchanger 5 and recirculated water 7 carries out heat exchange and cools 65 DEG C and enter absorption towers 1 and continue cycling through absorption sulfur trioxide through concentrated acid circulating pump 4.Most of heat of sulphuric acid is absorbed into steam generator system by desalted water and produces steam.Cooling circulating water amount required for reducing sulphuric acid temperature is greatly reduced, and corresponding cooling system also reduces.
This utility model simple in construction, practical function, utilize desalted water to pass through rustless steel heat-exchange system cooling sulphuric acid temperature, recovery waste heat, reduce quantity of circulating water, saved production cost.
