Abstract
An energy-saving double-tube heat exchanger comprises a water-phase outer sleeve and a gas-phase inner tube. The water-phase outer sleeve is divided into three sections including a first section, a second section and a third section according to a sequence from high temperature of gas to low temperature thereof, the gas-phase inner tube is an integrated coil penetrating through the heat exchanger from head to tail, and through the gas-phase inner tube among the sections of the water-phase outer sleeve is connected through pipe sections, so that the three sections of the water-phase outer sleeve attached on the inner tube are connected integrally. Afterheat from gas reaction is recycled sufficiently and used as a new energy resource to heat boiler water, and a circulating water system is replaced by the boiler water and lithium bromide refrigerant water, so that steam usage of a deaerator is saved. Temperature of demineralized water remains within a temperature range suitable for water treatment all the year round. The lithium bromide refrigerant water is used as cooling water, temperature of process gas at an outlet of a cooler can reach optimized index, and accordingly electricity consumption of an ammonia refrigeration ice maker is reduced greatly, the content of ammonia entering a synthetic tower is reduced simultaneously, and productivity of the synthetic tower is increased.
Description
Technical field
The present invention relates to the field of energy-saving technology of ammonia synthesizing industry synthesis procedure water cooler, is a kind of energy-saving double-tube heat exchanger specifically.
Background technology
So far, ammonia synthesizing industry synthesis procedure water cooler adopted shower type cooler and double-tube heat exchanger, and most of factory all eliminates the shower type cooler, adopts double-tube heat exchanger.The operation principle of shower type cooler is to walk to need the gas of cooling in the pipe, and the outside spreads cooling water; The operation principle of double-tube heat exchanger is the gas that interior pipe walks to need cooling, walk cooling water in the outer tube, both cooling waters all use recirculated water, cooling water all designs a cover closed cycle water system and finishes cooling thus, in construction investment, to increase the expense of a circulating water device, in production run, to increase the power consumption of water pump, the consumption of water, the circulating water treatment reagent consumption, also to produce sewer, increase recirculated water operational management post, device is safeguarded, recondition expense or the like, many once the cover circulating water device be equivalent to increase an energy resource consumption and operating cost.In addition, recirculated water is relatively poor at the cooling effect of scorching temperature period in summer, increased the load of ammonia cooler, thereby the ice maker load is increased the weight of, power consumption rises in a large number, influences the ammonia separative efficiency because of ammonia cooling effect difference simultaneously, causes ammonia content height in the synthetic tower inlet tower gas, synthetic tower production efficiency is descended, so be necessary very much to make improvements.
The utility model content
Technical problem to be solved in the utility model provide a kind of rational in infrastructure, device is simplified, the water-cooled a kind of energy-saving double-tube heat exchanger of synthesis procedure energy-conservation, efficient, that serviceability is good.
The utility model adopts following technical proposals to solve its technical problem:
A kind of energy-saving double-tube heat exchanger, comprise pipe in water outer tube and the gas phase, described water outer tube is divided into three sections, being arranged in order to low temperature from gas high temperature is one section, two sections and three sections, pipe is not cut apart in the described gas phase, be that a coiled pipe runs through heat exchanger head and the tail, in the gas phase pipe the section of water outer tube with section between be connected with pipeline section, will adhere on inner pipe three sections water outer tubes and be linked to be and be one.
The import of boiler demineralized water is established in the bottom that described water outer tube is a section, and the outlet of boiler demineralized water is established at the top; Heavy clear water import is established in two sections bottoms of described water outer tube, and heavy clear water output is established at the top; The import of lithium bromide chilled water is established in three sections bottoms of described water outer tube, and the outlet of lithium bromide chilled water is established at the top.
The utility model fully reclaims the waste heat of gas reaction as new thermal source heating boiler water, substitutes circulation with boiler water and lithium bromide chilled water simultaneously, has saved the steam consumption of oxygen-eliminating device; The temperature of demineralized water can all remain in the temperature range of suitable water treatment throughout the year; Cooling water is quoted the lithium bromide chilled water, makes the process gas temperature of cooler outlet reach the optimization index, has reduced the power consumption of ammonia refrigeration ice maker in a large number, has reduced synthetic tower simultaneously and has gone into the tower ammonia content, has improved synthetic output of column.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the double-tube heat exchanger structural representation of prior art.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model is divided into three groups with the double-tube heat exchanger assembly, comprises pipe 14 in water outer tube and the gas phase, and the water outer tube is attached on the interior pipe 14.Wherein the water outer tube is divided into three sections, arranges to low temperature from gas high temperature and is followed successively by one section sleeve pipe 1, two sections sleeve pipes 2 and three sections sleeve pipes 3.Boiler demineralized water import 6 is established in the bottom of one section sleeve pipe 1, and boiler demineralized water outlet 7 is established at the top; Heavy clear water import 8 is established in the bottom of two sections sleeve pipes 2, and heavy clear water output 9 is established at the top; Lithium bromide chilled water import 10 is established in the bottom of three sections sleeve pipes 3, and lithium bromide chilled water outlet 11 is established at the top.Pipe 14 is not cut apart in the gas phase, is that a coiled pipe runs through the heat exchanger head and the tail.In pipe 14 water overcoat pipeline section with section between be connected with pipeline section, three sections outer tubes be linked to be one, every section has all been designed the cleaning structure that do not stop.
The utility model fully reclaims the waste heat of gas reaction as new thermal source heating boiler water, substitute circulation with boiler water and lithium bromide chilled water simultaneously, one section cooling water is quoted the demineralized water before the boiler feed import, get back to boiler once more behind the heat of gas in one section pipe of demineralized water absorption and enter oxygen-eliminating device, oxygen-eliminating device inlet water temperature degree is raise; Two sections cooling waters are quoted company through a heavy clear water of handling, and absorb to get back to boiler behind the heat of the interior gas of two sections pipes once more and enter desalination workshop section and carry out desalination; Three sections cooling waters are quoted lithium bromide refrigerant cooling water and are quoted the lithium bromide chilled water, make the process gas temperature of cooler outlet reach the optimization index.
