Abstract
The utility model provides an anti-blocking heat exchanger, comprising a heat exchanger. A sea water pump is communicated with a shell side of the heat exchanger through a seawater inlet pipe stop valve; a fresh water pump is communicated with a tube side of the heat exchanger; the both ends of the shell side of the heat exchanger are further provided with a first reversing pipe and a second reversing pipe which are used for reversing; a first reversing pipe stop valve is arranged on the first reversing pipe; a second reversing pipe stop valve is arranged on the second reversing pipe; one ends of the first reversing pipe and the second reversing pipe are arranged at the both ends of the seawater inlet pipe stop valve; and a seawater outlet pipe stop valve is arranged between the other ends of the first reversing pipe and the second reversing pipe. According to the anti-blocking heat exchanger provided by the utility model, a seawater direction in the heat exchanger is changed by alternatively turning on and off the arranged reversing pipes and stop valves, and obstruction in the heat exchanger can be automatically taken away by using reversed flow of seawater pressure to achieve a smooth state, so that the obstruction in the heat exchanger can be removed when a ship diesel engine is at a normal operation state.
Description
Technical field
The utility model relates to a kind of H Exch, particularly a kind of anti-blocking H Exch of boat diesel engine fresh water that stops up dredger that has.
Background technology
The cooling system of boat diesel engine is the circulation enclosed type of cooling mostly; Promptly use seawater to pass through the fresh water H Exch and obtain cooling fresh water; In Fig. 1; Its cardinal principle is: sea water pump is pumped low temperature seawater to the fresh water H Exch, cools off the fresh water interchange of heat fuse instant heating exchanger tube side in it, thereby makes the hot fresh water cooling cooling in the fuse; The low temperature fresh water of cooling becomes hot water again and flow back into cooling once more, so circulation in the fresh water interchange of heat fuse after pumping the cooling diesel engine through fresh water pump.
The problem that this circulation enclosed type of cooling exists is: because the type of high-power diesel engine is little; The size of fresh water H Exch is also very little; Core, heat exchanger pipe in it has diameter little (4～6 millimeters of diameters), quantity characteristics how; When ship's navigation when containing the waters of impurity such as more floating debris, suspended matter, sea water pump is pumped seawater to the fresh water H Exch, the impurity in the seawater is easily attached to stopping up on the core, heat exchanger pipe and with H Exch; Thereby reduce the cooling performance of H Exch, influence the safe operation of diesel engine.At present; When ship's navigation ran into the H Exch stopping state, the manual removal tamper is carried out by the crewman in the back of generally taking to suspend made its mediation, and this not only needs the long time; (for example boats and ships are when overflow stage or torrent, the navigation of dangerous shoal leg also to be unfavorable for the safe operation of boats and ships; After fresh water H Exch shell side stops up,, will bring great potential safety hazard) to ship's navigation if can not in time handle.
Summary of the invention
The utility model technical matters to be solved provides a kind of anti-blocking H Exch; Can avoid the H Exch of existing ship diesel engine to cause the shortcoming of stoppage in transit because of obstruction; Can under the state of the normal operation of boat diesel engine, remove the tamper in the H Exch, thereby solve the problem of bringing potential safety hazard after boat diesel engine fresh water H Exch shell side stops up.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of anti-blocking H Exch; Comprise H Exch; Sea water pump is communicated with the H Exch shell side through seawater coolant inlet pipe shutoff valve, and fresh water pump is communicated with the H Exch tube side, and H Exch shell side two ends also are provided with first reversing tube and second reversing tube that is used to commutate.
Described first reversing tube is provided with the first reversing tube shutoff valve, and second reversing tube is provided with the second reversing tube shutoff valve.
One end of described first reversing tube and second reversing tube is positioned at the two ends of seawater coolant inlet pipe shutoff valve, is provided with seawater coolant outlet pipe shutoff valve between the other end of first reversing tube and second reversing tube.
The two ends of described first reversing tube all are positioned at before the two ends of second reversing tube.
During described H Exch normal operation, seawater coolant inlet pipe shutoff valve and seawater coolant outlet pipe shutoff valve are opened, and the first reversing tube shutoff valve and the second reversing tube shutoff valve are in closed condition.
Described H Exch shell side takes place to stop up when dredging, and seawater coolant inlet pipe shutoff valve and seawater coolant outlet pipe shutoff valve are closed, and the first reversing tube shutoff valve and the second reversing tube shutoff valve are in opening.
A kind of anti-blocking H Exch that the utility model provides; Flow to through the reversing tube of setting and the seawater that changes in the H Exch that alternately opens and closes of shutoff valve; Utilize the sea pressure counter-flow to take away the tamper in the H Exch automatically and reach unimpeded state; Can under the state of the normal operation of boat diesel engine, remove the tamper in the H Exch; Avoid the fresh water H Exch of existing ship diesel engine to cause the shortcoming of stoppage in transit, thereby solve the problem of bringing potential safety hazard after boat diesel engine fresh water H Exch shell side stops up because of obstruction.The utility model is rational in infrastructure, makes simple, with low cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is existing H Exch integral structure scheme drawing.
The integral structure scheme drawing of Fig. 2 the utility model.
Among the figure: H Exch 1, heat exchanger tube side 2, sea water pump 3, fresh water pump 4; Seawater coolant inlet pipe 5, seawater coolant outlet pipe 6, seawater coolant inlet pipe shutoff valve 7, the first reversing tubes 8; Second reversing tube, 9, the first reversing tube shutoff valves, 10, the second reversing tube shutoff valves 11, seawater coolant outlet pipe shutoff valve 12.
The specific embodiment
A kind of anti-blocking H Exch; Comprise H Exch 1; Sea water pump 3 is communicated with the H Exch shell side through seawater coolant inlet pipe shutoff valve 7, and fresh water pump 4 is communicated with H Exch tube side 2, and H Exch shell side two ends also are provided with first reversing tube 8 and second reversing tube 9 that is used to commutate.
Described first reversing tube 8 is provided with the first reversing tube shutoff valve, 10, the second reversing tubes 9 and is provided with the second reversing tube shutoff valve 11.
