Abstract
The utility model relates to a tube type heat exchanger, which mainly comprises a cylinder body and condenser tubes. The cylinder body is a hollow cylindrical structure, one side of the cylinder bodyis equipped with a cooling water inlet or a cooling water outlet respectively, the condenser tubes are mounted in an inner cavity of the cylinder body, one end of each upper-layered condenser tube isequipped with a steam inlet, one end of each lower-layered condenser tube is provided with a condensation water outlet, and the condenser tubes are connected with each other via connecting elbows. Steam which is mixed with ammonium nitrate and other substance components and is sucked from a puffing crystallizing tank via a negative-pressure system enters the condenser tubes directly to be isolatedfrom cooling water filled inside the inner cavity of the cylinder body, then liquid and gas perform heat transfer via pipe walls, and the condensation water is collected via a collecting tank to be reused as solution water to be added into an ammonium nitrate dissolving tank, thereby realizing zero discharge of pollutants and resolving environmental pollution during the production process. Because the condensation water can be recycled, water resources and raw materials such as ammonium nitrate and the like can be saved, thereby greatly reducing production cost.
Description
[technical field]
The utility model relates to a kind of condensing unit, relates in particular to a kind of with the moisture vaporization and the water vapor condensation that forms becomes the tubular heat exchanger of aqueous water in puffing process of ammonium nitrate and oil phase mixed solution.
[background technology]
In the bulking ammonium nitrate explosive production process, expanded crystallization process can produce a large amount of steam because of the moisture gasification, takes ammonium nitrate and other material composition of part when steam is overflowed out of, and needing to be condensed into aqueous water by condensing plant could discharge with cooling water.Former process using be direct contact condenser, a large amount of steam that expanded crystallization process produces are inhaled into direct contact condenser under the effect of negative pressure system, steam and cooling water directly contact and carry out heat exchange and form condensed water, be disposed to sedimentation basin with cooling water then, emit again through post precipitation.Though this heat transfer condensing mode device structure is simple, equipment cost and production maintenance cost are lower, owing to contain ammonium nitrate and some other harmful substance compositions in the condensed water of discharging, easily cause the pollution to environment, are unfavorable for environmental protection.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of not only played condensation, but also the not also recyclable utilization of polluted source, condensed water, the also cost-saved tubular heat exchanger of environmental protection not only.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tubular heat exchanger, mainly contain cylindrical shell and condenser pipe, and cylindrical shell is the hollow cylinder body structure, is respectively equipped with cooling water inlet or coolant outlet in a side of cylindrical shell; Inner chamber at cylindrical shell is equipped with some condenser pipes, its at the middle and upper levels condenser pipe one end be provided with the steam import, lower floor's condenser pipe one end is provided with condensation-water drain, links by bridge piece between each condenser pipe.
Described cylindrical shell divides two-layer installation arranged side by side up and down, links by adpting flange and connecting line between the two-layer up and down cylindrical shell.
The condensation-water drain of described condenser pipe links by flange and pipeline and collecting tank import, and directly communicates with collecting tank.
The beneficial effects of the utility model are: directly enter condenser pipe by negative pressure system from the steam that is mixed with ammonium nitrate and other material composition that expanded crystallizing tank sucks, do not contact mutually with the cooling water that is full of cylinder lumen, liquid and gas carry out heat transmission by tube wall, condensed water is collected by collecting tank, again join the ammonium nitrate dissolving tank as dissolving water, realize zero release of pollutant, finely solved problem of environmental pollution in the production process; Because water resource has not only been saved in the recyclable utilization of condensed water, has also saved raw material such as ammonium nitrate, effectively reduces production cost.Proportion by solution in the actual measurement collecting tank is 1.10, and ammonium nitrate concn is 30%, and recovery utilization rate is 0.5%～1.5% of a production.The per 10 tons of ammonium nitrate of expanded pharmaceutical manufacturing process need add 800 kilograms in dissolving water, the rate of recovery of condensed water is about 80%, to produce 18000 tons production capacity calculating, the annual ammonium nitrate that approximately can save 340 tons per year, calculate for 2300 yuan with current ammonium nitrate, can save more than 70 ten thousand yuan in 1 year.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A to structural representation;
Fig. 3 is a B-B cross-sectional view among Fig. 1.
Among the figure: 1-cylindrical shell, 2-condenser pipe, 3-connecting line, 4-cooling water inlet, 5-coolant outlet, 6-inner chamber, 7-bridge piece, the import of 8-steam, 9-condensation-water drain.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of tubular heat exchanger mainly contains cylindrical shell 1 and condenser pipe 2, and cylindrical shell 1 is the hollow cylinder body structure, and the two-layer installation arranged side by side up and down in 1 fen of this cylindrical shell links by adpting flange and connecting line 3 between the two-layer up and down cylindrical shell 1; Side at cylindrical shell 1 is respectively equipped with cooling water inlet 4 or coolant outlet 5; Inner chamber 6 at each layer cylindrical shell 1 is separately installed with 32 condenser pipes 2, condenser pipe 2 is the stainless steel tube of Φ 57x2.5, its at the middle and upper levels condenser pipe 2 one ends be provided with steam import 8, lower floor's condenser pipe 2 one ends are provided with condensation-water drain 9, link by bridge piece 7 between each condenser pipe 2; The condensation-water drain 9 of described condenser pipe 2 links by flange and pipeline and collecting tank import, and directly communicates with collecting tank.During work, cooling water directly enters in the inner chamber 6 of cylindrical shell 1, until being full of whole cavity; Then enter condenser pipe 2 by negative pressure system from the steam that is mixed with ammonium nitrate and other material composition that expanded crystallizer sucks, gas enters in the upper strata condenser pipe 2 from the steam import 8 on the right earlier, flow from right to left, bridge piece 7 by the left side enters lower floor's condenser pipe 2, flow from left to right again, steam does not contact mutually with cooling water in the condenser pipe 2, liquid and gas carry out heat transmission by tube wall, be condensed into condensed water gradually, condensation-water drain 9 links to each other with the collecting tank import by flange and pipeline and directly enters collecting tank, adds the ammonium nitrate dissolving tank as dissolving water when needed by collecting tank again and recycles.
The utility model carries out heat transmit with the steam that is sucked by negative pressure system by the metal wall with cooling water makes water vapor condensation become aqueous water, cooling water does not contact by the metal wall is isolated mutually with condensed water, be independent of each other between the two, cooling water can directly discharge, condensed water then collects by a collecting tank, collecting tank links to each other with the ammonium nitrate dissolving tank, condensed water can be used as dissolving water and is joined again in the ammonium nitrate dissolving tank and need not discharge, and has solved problem of environmental pollution maximum in the bulking ammonium nitrate explosive production process effectively.
