Abstract
The utility model discloses an external guiding flow baffle-rod type closed circulating water heat exchanger which belongs to a heat exchanger without direct contact with heat exchanging medium, in particular to a heat exchanger used for a fixed tubular channel component with two heat exchanging mediums. The heat exchanger comprises a tube box, a tube shell, a tube plate, a tube bank, a tube side water inlet, a tube side water outlet, a shell side water inlet and a shell side water outlet. The heat exchanger has the structure that the water inlet and the water outlet of the shell side are respectively provided with an external guiding flow cylinder, the outer wall and the inner wall of the external guiding flow cylinder form an annular flow guiding cavity, and the shell side water inlet and the sell side water outlet are respectively communicated with the annular flow guiding cavity; at least three grid plates vertical to the tube bank is arranged in the housing. The heat exchanger overcomes the defects that a traditional baffle-plate type closed circulating water heat exchanger is easy to induce the vibration of the tube bank, the hydraulic resistance beside a shell is large, and the like. The flow direction of the fluid among tubes beside the shell is longitudinal direction, the flow speed is even without stagnation zone, the tube layout area of the tube bank is increased, the heat transfer coefficient is high, the hydraulic resistance beside the shell is small, and the vibration of the tube bank can be prevented effectively.
Description
Technical field
The utility model belongs to the not direct heat-exchange apparatus of contact of heat exchange medium, especially for the heat-exchange device of the fixed pipe channels assembly of two kinds of heat exchange mediums.
Background technology
The closed cycle water heat exchanger is a kind of water hydrothermal exchange equipment that does not have phase transformation, the shell-and-tube heat exchanger that present power plant closed cycle water heat exchanger is adopted, and shell-side adopts traditional baffle plate type tube bundle support, flow-guiding structure mostly.Along with the large scale development of Power Plant, the closed-type circulating cooling water amount of the required cooling of single device is increasing.Heat exchanger area is big, heat exchange pipe range, wall are thin.Use traditional baffle plate type tube bundle support, flow-guiding structure, the phenomenon that causes tube bundle vibration to damage happens occasionally, and the shell fluid resistance is also increasing.Its reason is exactly the baffle plate type structure, deflection plate has the double action of tube bundle support and control shell fluid flow velocity, shell fluid is to the tube bank transversal flow, and the big and baffle(s) spacing big (just no-support spaning distance is big) of crossflow velocity all easily causes the tube bundle vibration damage.Along with the increase of the shell-side water yield, the big and baffle(s) spacing of crossflow velocity this contradiction greatly will be more and more inevitable.And traditional baffle plate type tube bundle support, flow-guiding structure, fluid inlet needs very big not stringing zone to satisfy the circulation area requirement in order to guarantee tube bank not to be impacted, and also has the local stagnant area that does not participate in heat exchange in addition in the deflection plate bight.
The utility model content
In order to overcome traditional baffle plate type tube bundle support, flow-guiding structure, cause that easily to bring out tube bundle vibration and shell fluid resistance big etc. not enough, the purpose of this utility model provides a kind of outer water conservancy diversion deflection bar type closed cycle water heat exchanger, this outer water conservancy diversion deflection bar type closed cycle water heat exchanger not only can reduce the shell fluid resistance and prevent the tube bank vibrations, and can increase tube bank stringing area in the housing, improve exchange capability of heat.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of outer water conservancy diversion deflection bar type closed cycle water heat exchanger, comprise bobbin carriage, shell, tube sheet, tube bank, tube side intake-outlet, shell side intake-outlet, its structure is: go out to be respectively equipped with external flow guiding cylinder at shell side water inlet and delivery port, external flow guiding cylinder outer wall and external flow guiding cylinder inwall are formed annular diversion cavity, the shell side intake-outlet communicates with the water conservancy diversion ring cavity respectively, and at least 3 roads screen vertical with tube bank is housed in the housing.
Described screen is made up of support ring that links to each other with housing and the deflection plate that is parallel to each other that is welded on the support ring.
Described deflection plate is that the spacing of round steel or steel plate bar adjacent baffle is 2 times of adjacent heat exchange tubes spacing.
Fluid import department is provided with external flow guiding cylinder on the disclosed heat exchanger shell of the utility model, makes shell fluid not in the direct side knock tube bank of import department, is guided to shell end and is circumferentially evenly entering tube bank; Coral plate group adopt is supported in tube bank, and the heat exchanging tube bank is supported and exchange between heat pipe fluid along heat exchanger tube disturbance longitudinally; Fluid outlet also is provided with external flow guiding cylinder on the housing, make shell fluid through tube bank with close the inner fluid heat exchange after the exit external flow guiding cylinder of flowing through flow out and finish heat transfer process.
The beneficial effects of the utility model are that closed cycle water heat exchanger that this heat exchanger has overcome traditional baffle plate type tube bundle support, flow-guiding structure exists and easily to bring out deficiencies such as tube bundle vibration and shell fluid resistance are big, meet the heat exchange principle, direction of flow is that longitudinal stream, flow velocity evenly do not have the stagnant area between the shell-side pipe, optimize the cloth tubular construction, make stringing space availability ratio height, the heat transfer coefficient height, the shell fluid resistance is little, can effectively prevent tube bundle vibration.It is a kind of energy-efficient heat transmission equipment.
