For solving the problems of the technologies described above, the utility model provides a kind of cooling system of energy on-line cleaning heat exchanger, comprise at least two branch roads, described branch road comprises heat exchanger and blowoff valve, the two ends of described heat exchanger are connected with trunk inlet pipeline, trunk water return pipeline respectively by arm, described trunk water return pipeline is provided with the trunk backwater valve, be separately installed with inlet valve and backwater valve on two side branch of described heat exchanger simultaneously, described blowoff valve is installed on the arm between described heat exchanger and its inlet valve, and described blowoff valve is connected with blow-off pipe.
The cooling system of the energy on-line cleaning heat exchanger that the utility model provides, by at bye-pass blow-off pipe and sewage draining valve being installed, realize the on-line cleaning of heat exchanger, avoid time-consuming off-line to clean, also need not complicated advancing the water return pipeline switching device or add in addition flushing pipe pump flush mode in the prior art.
Description of drawings
Fig. 1 is the pipeline connection diagram of at present general water-cooled heat-exchange system;
The connection diagram of the cooling system of the energy on-line cleaning heat exchanger that Fig. 2 provides for the utility model embodiment.
The specific embodiment
Referring to Fig. 2, the cooling system of a kind of energy on-line cleaning heat exchanger that the utility model embodiment provides comprises at least two branch roads, and this branch road comprises heat exchanger 11 and blowoff valve 10; The two ends of heat exchanger 11 are connected with trunk inlet pipeline 4, trunk water return pipeline 5 respectively by arm, the trunk water return pipeline is provided with the trunk backwater valve, be separately installed with inlet valve 6 and backwater valve 7 on two side branch of heat exchanger 11 simultaneously, blowoff valve 10 is installed on the arm of 6 of heat exchanger 11 and its inlet valves, and blowoff valve 10 is connected with blow-off pipe 8.
Wherein, this cooling system also is equipped with blowoff valve 12 on the arm of 7 of heat exchanger 11 and its backwater valves, and this blowoff valve 12 is connected with blow-off pipe 9;
Wherein, this cooling system also comprises UNICOM's pipeline on the branch road of heat exchanger 11, on this UNICOM's pipeline UNICOM's valve 13 is installed, and an end of UNICOM's pipeline and the inlet valve 6 of heat exchanger 11 are connected with branch road pipeline between the trunk inlet pipeline 4, and the other end and the backwater valve 7 of heat exchanger 11 are connected with branch road pipeline between the heat exchanger 11;
Wherein, this cooling system also connects UNICOM's pipeline between trunk inlet pipeline 4, trunk water return pipeline 5, UNICOM's valve 3 is installed on UNICOM's pipeline, and an end of UNICOM's pipeline is connected with trunk inlet pipeline 4, and the other end is connected with trunk water return pipeline 5.
Certainly, when this cooling system includes above-mentioned UNICOM's pipeline and UNICOM's valve, no matter be the branch road that is connected to the heat exchanger place, or be connected with the trunk outlet pipe with the trunk water inlet pipe, this cooling system equally also can solve the problem to be solved in the present invention in the situation that only comprises a branch road.
Below be the use principle of the cooling system of the energy on-line cleaning heat exchanger that provides of the utility model:
At first, close the inlet valve 6 of the described heat exchanger 11 place branch roads that need to be cleaned, open the water inlet sewage draining valve 10 of this branch road, close simultaneously the backwater sewage draining valve 12 of this branch road; Then, close the trunk backwater valve 2 of trunk water return pipeline 5, the valve of other branch roads keeps normal duty, and namely inlet valve 6 and backwater valve 7 all are in the state of opening; At last, the backwater of cooling system is all discharged from the water inlet sewage draining valve 10 of this branch road; Certainly, the heat exchanger 11 that is cleaned can be one, also can be a plurality of, after this branch road that is cleaned carries out back flush, can also close the backwater valve 7 of this branch road, close simultaneously the water inlet sewage draining valve 10 of this branch road, open this branch road backwater sewage draining valve 12, open the inlet valve 6 of this branch road, realize that forward washes to reach the purpose that increases developing result;
