Abstract
The invention relates to a back flushing device of a brazed plate heat exchanger in a cooling water loop. The back flushing device is characterized by comprising an open-type cooling tower, a Y-shaped filter and a brazed plate heat exchanger, wherein the cooling tower, the Y-shaped filter and the brazed plate heat exchanger are connected through pipelines; the back flushing device also comprises a steering component, wherein the steering component is arranged between the Y-shaped filter and the brazed plate heat exchanger, and comprises a steering pipe and a valve which is connected with the steering pipe; and when the brazed plate heat exchanger is subjected to back flushing, back flushing is finished by water flow through the steering pipe. Compared with the prior art, the back flushing device of the brazed plate heat exchanger in the cooling water loop has the advantages that 1) the back flushing device is simple in structure, convenient to flush, and low in cost; 2) with the adoption of the back flushing device, the inner of the brazed plate heat exchanger can be kept clean at any time, the heat exchange efficiency is higher, the energy can be saved and the environment can be protected; and 3) with the adoption of the back flushing device, the service life of the brazed plate heat exchanger can be greatly prolonged, and the back flushing device is beneficial for being popularized and applied on a large scale.
Description
Technical field
The present invention relates to a kind of back flush apparatus, relate in particular to back flush apparatus and the back flush method of brazing plate type heat exchanger in a kind of open type cooling water loop.
Background technology
Be easy in water in open type cooling water loop enter various foreign material and a large amount of dust, various foreign material are easy to block pipeline, and because in whole loop, the aperture of brazing plate type heat exchanger is minimum, therefore, this aperture the most easily gets clogged.Can heat transfer effect be had a strong impact on after aperture gets clogged, even cannot normally work.Because brazing plate type heat exchanger cannot be unpicked and washed, in order to solve the problem, those skilled in the art are also constantly attempting new method, normally add y-type filter in pipeline again in prior art, many foreign material filter, but Problems existing is as follows, 1) conventional y-type filter can not filter out all foreign material completely, have the part divine force that created the universe and enter pipeline, in the course of time, aperture still can get clogged; 2) if y-type filter strengthens order number also can increase pipeline on-way resistance, strengthen the lift demand of water pump, can increase pump consumption, therefore, a kind of new equipment of exigence solves above-mentioned technical problem.
Summary of the invention
The present invention is just for the technical problem existed in prior art, there is provided that a kind of structure is simple, the back flush apparatus of brazing plate type heat exchanger in easy to clean, lower-cost open type cooling water loop, this back flush apparatus can keep clean clean in brazing plate type heat exchanger constantly, heat exchange efficiency is higher, more energy-conserving and environment-protective.
To achieve these goals, technical scheme of the present invention is as follows, the back flush apparatus of brazing plate type heat exchanger in cooling water loop, it is characterized in that, described back flush apparatus comprises open cooling tower, y-type filter, and brazing plate type heat exchanger, described cooling tower, y-type filter, and connected by pipeline between brazing plate type heat exchanger, described back flush apparatus also comprises steering assembly, and described steering assembly is arranged between y-type filter and brazing plate type heat exchanger; Described back flush apparatus also comprises valve one, valve two, and described valve two is arranged on the entrance side of open cooling tower, and described valve one is arranged on the outlet side of y-type filter; Described back flush apparatus also comprises blowdown assembly, even if back flush dirt is discharged by blowdown assembly; The valve three that described steering assembly comprises steering tube and is connected with steering tube; The valve four that described blowdown assembly comprises blow-off pipe and is connected with blow-off pipe.Back flush dirt is discharged in time by blow-off pipe, guarantees clean in device, clean.
A kind of back flush method of the back flush apparatus of brazing plate type heat exchanger in open type cooling water loop, it is characterized in that, during normal operating conditions, valve one, valve two are opened, valve three, valve four are closed, and during back flush, valve three, valve four are opened, valve one, valve two are closed, and the dirt after back flush is discharged through blow-off pipe.
relative to prior art, advantage of the present invention is as follows, 1) provide that a kind of structure is simple, easy to clean, cost are lower; 2) this back flush apparatus can keep clean clean in brazing plate type heat exchanger constantly, and heat exchange efficiency is higher, more energy-conserving and environment-protective; 3) this back flush apparatus can extend the service life of brazing plate type heat exchanger greatly, is convenient to apply on a large scale.
