Description
Technical field
The present invention relates to a kind of heat-exchange device, relate in particular to a kind of heat-exchange device that cooling water is provided for producing steel pipe.
Background technology
At present, production technology of steel tube needs three modules, wherein, module 1: canned liquefied ammonia is released into ammonia and decomposes facility, after ammonia decomposes, by providing for workshop, produce indispensable hydrogen and nitrogen, in discharging gas process, the tank mouth valve of ammonia tank will produce a large amount of heats, this heat must be lowered the temperature by cooling water, otherwise will cause the overheated explosion caused danger of tank body; Module 2: cooler is that the cooling water that workshop is used is lowered the temperature, prevents from causing not in time because equipment, product are cooling device damage or product bad; Module 3: liquid nitrogen container is produced necessary source of the gas for workshop provides, and when nitrogen becomes gaseous state from liquid state, need to absorb a large amount of heats causes gasifier surface to freeze throughout the year.
The defect of prior art: for module 1, need the moment ceaselessly the tank mouth valve of ammonia tank to be carried out cooling, cooling water is arranged outward, and energy consumption is larger; For module 2, cooling-water machine energy consumption is larger, and equipment investment is larger, and use occasion is had relatively high expectations, and noise is larger; For module 3, gasifier surface freezes, and causes endothermic effect poor.In addition, three modules are respectively done for oneself, and battalion, energy consumption are large, uneconomical, not environmental protection.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, provide a kind of heat to three pack modules to recycle, reduce energy loss, improve the utilization rate of cooling water and the heat-exchange device of cooling effectiveness.
The technical solution adopted for the present invention to solve the technical problems is: a kind of heat-exchange device, comprise the ammonia tank that liquefied ammonia is housed, the liquid nitrogen container of liquid nitrogen and the workshop of place apparatus and product are housed, described liquid nitrogen container is communicated with the import of high-pressure pump by pipeline, this high pressure delivery side of pump is communicated with the import of gasifier by pipeline, the outlet of this gasifier is communicated with the import of workshop by pipeline, described gasifier is immersed in the bosh of sealing, this device also comprises chilled(cooling) water return (CWR), this chilled(cooling) water return (CWR) comprises by the first cooling water pipeline of ammonia tank tank mouth valve with by equipment in workshop, the second cooling water pipeline of product, on described bosh, be provided with cooling water intake and cooling water outlet, this cooling water outlet is communicated with the water inlet of the second cooling water pipeline, the delivery port of the second cooling water pipeline is communicated with the water inlet of the first cooling water pipeline, the delivery port of the first cooling water pipeline is communicated with the cooling water intake of bosh.
Described bosh is the container of being made by stainless steel.
The cooling water intake of described bosh is arranged on bosh one side roof part, and its cooling water outlet is arranged on bosh opposite side bottom.
Beneficial effect: (one) chilled(cooling) water return (CWR) is communicated with ammonia tank, bosh and workshop, cooling water reusable edible, every day, saving water resource reached 3 tons, and can replace 5 cooling-water machine work, and save 150,000 yuan of equipment investments, save electric weight approximately 300 degree every day, save floor occupying area 40 square metres, reduce 5 of recycle column, economize on the use of funds 2.5 ten thousand yuan, economic interests are very remarkable.(2) treating capacity of cooling water of the present invention and the matching of production are very good, and water temperature is constant, and equipment, Product Status are all very good.(3) adopt temperature lower, stable, without the cooling water of granule foreign, tube product surface is carried out coolingly, improved product quality, reduced the working condition large hidden danger that fluctuates, greatly improved yield rate.(4) reduce the cooling-water machine of workshop, reduced noise pollution, improved the protection to operating personnel.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of the preferred embodiments of the present invention.
Wherein: 1, ammonia tank; 2, liquid nitrogen container; 3, workshop; 4, high-pressure pump; 5, gasifier; 6, bosh; 7, chilled(cooling) water return (CWR).
The specific embodiment
A kind of heat-exchange device as shown in Figure 1, comprise be equipped with liquefied ammonia ammonia tank 1, the liquid nitrogen container 2 of liquid nitrogen and the workshop 3 of place apparatus and product are housed.Described liquid nitrogen container 2 is communicated with the import of high-pressure pump 4 by pipeline, and the outlet of this high-pressure pump 4 is communicated with the import of gasifier 5 by pipeline, and the outlet of this gasifier 5 is communicated with the import of workshop 3 by pipeline.Described gasifier 5 is immersed in the bosh of being made by stainless steel 6 of sealing.This device also comprises chilled(cooling) water return (CWR) 7, this chilled(cooling) water return (CWR) 7 comprises by the first cooling water pipeline of ammonia tank 1 tank mouth valve with by equipment in workshop 3, the second cooling water pipeline of product, on described bosh 6, be provided with cooling water intake and cooling water outlet, its cooling water intake is arranged on bosh 6 one side roof parts, its cooling water outlet is arranged on bosh 6 opposite side bottoms, this cooling water outlet is communicated with the water inlet of the second cooling water pipeline, the delivery port of the second cooling water pipeline is communicated with the water inlet of the first cooling water pipeline, the delivery port of the first cooling water pipeline is communicated with the cooling water intake of bosh 6.
Operation principle: for the cooling water of cooling ammonia tank 1 tank mouth valve, after cooling, the water temperature of this cooling water is about 50 ℃, then by pipeline, flow into bosh 6, when the liquid nitrogen in liquid nitrogen container 2 is converted into gaseous nitrogen atmosphere, need to absorb a large amount of heats, it is first by high-pressure pump 4, then by gasifier 5, because gasifier 5 is immersed in bosh 6, now, nitrogen will be taken away the heat of water in container, water temperature in container will reduce, because the inflow of cooling water and the outflow of nitrogen are synchronously carried out, so, in bosh 6 be water-cooled to 10 ℃ of left and right time, cooling water flows into workshop 3 by pipeline, supply with workshop appliance, product is done cooling water source, then cooling water absorbs after heat by the pipeline ammonia tank 1 tank mouth valve of flowing through again, to ammonia tank 1 tank mouth valve, carry out cooling, because circulating in water route, so in running, water temperature is constant.
Should be appreciated that specific embodiment described above, only for explaining the present invention, is not intended to limit the present invention.The apparent variation of being extended out by spirit of the present invention or change are still among protection scope of the present invention.
