Abstract
The utility model relates to an ammonia cooler, which comprises a casing, heat exchanging tubes, baffle plates and a tube sheet. Ends of the heat exchanging tubes are connected to a heat exchanging tube bundle through the tube sheet and positioned inside the casing, and the baffle plates are arranged among the heat exchanging tubes. The ammonia cooler is characterized in that the heat exchanging tubes are made of bent transverse grooved tubes, annular ribs are arranged on the inner wall of the transverse grooved tubes, and the ratio of the space tp to the height e of the annular ribs is 8-32. Compared with the prior art, the ammonia cooler has the advantages that firstly, the transverse grooved tubes serves as the heat exchanging tubes of the ammonia cooler for the first time, heat exchanging can be enhanced when fluid flows through the annular ribs in the tubes by changing the tube structure, and heat efficiency can be improved while enough heat exchanging area and occupied area are guaranteed, secondly, water resource and energy consumption can be reduced, economic efficiency can be improved, and realization of energy saving and emission reduction in chemical industry can be benefited.
Description
Technical field
The utility model relates to ammonia steaming system field, coke-oven plant, particularly a kind of ammonia cooler that improves the ammonia heat exchange efficiency.
Background technology
In the coke-oven plant, traditional ammonia cooler generally adopts U type tubular structure heat exchanger, and U type pipe adopts the common metal drawn tube to bend, the outer ammonia of cooling water in the pipe and pipe carries out heat exchange, reach the ammonia cooling purpose, this device can not reach heat exchange efficiently, and used cooling water inflow is big, place for the water resource relative shortage, the consumption of water resource is big, the expense height of operation, therefore, for pursuing the design concept of energy-saving and emission-reduction, need a kind of cooler more efficiently.
Summary of the invention
The purpose of this utility model provides a kind of ammonia cooler, overcomes the deficiencies in the prior art, improves the heat exchange efficiency of heat exchanger tube, realizes the purpose of energy-saving and emission-reduction.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of ammonia cooler comprises housing, heat exchanger tube, deflection plate, tube sheet, and many heat exchanger tube ends connect into heat-exchanging tube bundle by tube sheet and place in the housing, are provided with deflection plate between the heat exchanger tube, and described heat exchanger tube adopts cross grooved pipe to bend.Described cross grooved pipe inwall is provided with the ring-type lug, nib, and the ratio of described ring-type lug, nib spacing tp and height e is 8～32.
Compared with prior art, the beneficial effects of the utility model are: 1) adopt cross grooved pipe as heat exchanger tube in ammonia cooler first, by changing the tube side structure, heat exchange is strengthened when making in the fluid flowing pipe fin, guaranteeing to have increased heat exchange efficiency under the enough heat exchange area and shared steric requirements; 2) can reduce the consumption of the water resource and the energy, increase economic efficiency, help the realization of chemical industry energy-saving and emission-reduction.
Description of drawings

Fig. 2 is the cross grooved pipe partial sectional view.
Among the figure: 1-housing 2-heat exchanger tube 3-deflection plate 4-tube sheet 5-ring-type lug, nib
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of ammonia cooler structural representation of the utility model, comprise housing 1, heat exchanger tube 2, deflection plate 3, tube sheet 4, many heat exchanger tube 2 ends connect into heat-exchanging tube bundle by tube sheet 4 and place in the housing 1, vertically be provided with deflection plate 3 between the heat exchanger tube 2, heat exchanger tube 2 adopts cross grooved pipe to bend, and makes the cooling water of tube side and the ammonia of shell side carry out heat exchange, the parts that contact with ammonia adopt stainless steel 22Cr17Ni12Mo2 to manufacture and design, to avoid corrosion.
Seeing Fig. 2, is the cross grooved pipe partial sectional view, and the cross grooved pipe inwall is provided with ring-type lug, nib 5, and the ratio of ring-type lug, nib spacing tp and height e is 8～32.Cross grooved pipe is to be formed by common pipe rolling, fluid flows through ring-type lug, nib 5 can form whirlpool and strong disturbance, thereby strengthened the heat exchange effect, the effect of strengthening depends on the ratio of ring-type lug, nib spacing tp and height e, the whirlpool of cross grooved pipe mainly forms at the tube wall place, the influence of convection cell main flow is less, so its flow resistance is littler than the helix tube of same pitch and groove depth.Practice is measured and is shown, the coefficient of heat transfer of the comparable common smooth wall pipe of cross grooved pipe improves 1.4～1.7 times.The utility model adopts cross grooved pipe to substitute traditional light wall metallic pipe, not only makes simply, and can effectively increase the heat exchange area of heat exchanger tube self, thereby enlarge markedly heat exchange efficiency.
