Description
Technical field
The utility model is specifically related to a kind of leak-proof heat converter device, and it has been applied to heat-exchangers of the plate type equipment, is particularly ensureing to have advantage in the firm of water-wind-heat switching equipment and leakproof.
Background technology
What the employing of annealing furnace slow cooling section was moved back by cold rolling three companies is board-like water-wind-heat interchanger, the circulated air of releasing from Lu Qu refills stove district purging at belt steel surface after cooling water heat exchanger cools, and plays and makes it reach the effect of suitable crystalline temperature to the cooling of band steel.Cold rolling mill annealing furnace slow cooling section air cooler onsite application situation is always unstable, heat exchanger cracky, the equipment that occurs frequently reveals fault, cause the oxide generated because of cooling section regional water too high levels to cause three to connect and move back the abnormal white point of panel surface, annealing finished product is made to change the original sentence to too much qualification rate not high, simultaneously, due to heat exchanger employing is overall structure, once find that belt steel surface exists white-spot defects, just must change whole heat exchanger to ensure board surface quality, both have impact on normal production, the cost too increase spare part maintenance, changing.
The main cause that existing heat exchange equipment is revealed: one is because existing heat exchanger adopts nest plate type structure, this structure has compact conformation, the advantage that heat transfer efficiency is high, but in use to the wind speed in air channel, blast has strict requirement, its air channel of Long-Time Service, the windage of air cooler windward side can be aggravated, and existing heat exchanger windward side about 9.5 ㎡, width only has 400mm, and the weight of whole heat exchange core group is all born by support tube sheet and the pipe plate that rises, add that heat exchanger tube span is more than 3m, equipment affects by air channel wind-force and equipment self gravitation when running, whole heat exchange core group is pendulum model motion, the low-frequency vibration of equipment is made to exceed normal range (NR), thus cause fixed tube sheet and heat exchanger tube to rub frequently, clash into, accelerate the wearing and tearing of heat exchanger tube interface, heat exchanger tube is finally caused to break, equipment is revealed, two is because the inner flow passage of existing heat exchanger is four flow process single channels, only has a circulated close to the diversion boxs of 3 meters, and not reserved emergent space, as device fails, even trickle seepage, integral device just must close down, change.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of leak-proof heat converter device, which increases structural strength and crashproof antifriction ability, heat exchanger effectively can be prevented damaged, and optimize runner design, improve emergency capability.
The utility model solves the technical scheme that its technical problem adopts:
A kind of leak-proof heat converter device, this device comprises nest plate, two ends support the heat exchanger tube be arranged on described nest plate and the bobbin carriage being arranged on described heat exchanger tube two ends, described heat exchanger tube comprises upper and lower two groups, often organize heat exchanger tube and be all provided with independent cooling water inlet and coolant outlet, separated by dividing plate between two groups of heat exchanger tubes, the two ends of described dividing plate are arranged on nest plate, direction perpendicular to heat exchanger tube in described nest plate is provided with two pieces of support tube sheets, described support tube sheet evenly offers the installing hole for installing heat exchanger tube.
By technique scheme, described installing hole is flanging bore, and the length of described flanging bore is greater than the thickness supporting tube sheet.
By technique scheme, the length of described flanging bore is 6 ~ 8mm.
By technique scheme, this device also comprises and is arranged on two closed aqueducts corresponding with two groups of heat exchanger tubes on bobbin carriage, and described closed aqueduct is communicated with corresponding heat exchanger tube pipe bent position.
By technique scheme, described closed aqueduct is provided with valve.
The utility model, there is following beneficial effect: under the prerequisite of the normal blast of the equipment of guarantee, windage, this device is by increasing by two pieces of support tube sheets in nest plate middle part, change original 2 supports into four-point supporting, to reduce the abutment pressure at heat exchanger tube interface position, reduce the low-frequency vibration of device when stressed; Simultaneously; heat exchanger tube is divided into two groups; by each for original both sides overall runner chamber; change each upper and lower two the runner point water chamber in both sides into, two runners divide water chamber to isolate, even if equipment is revealed; that can close its corresponding runner enters penstock; when do not need shut down, can assurance device also have 50% exchange capability of heat, reserved enough crash times.The utility model novel structure, manufactures simple, easy for installation, safeguard easily, to preventing plate type heat exchanger water leakage fault to have remarkable result, the effect improving heat exchanger structure intensity can be reached simultaneously, having that effect is perfect, working stability, maintenance is simple, technological transformation expense is low advantage.
