Description
Technical Field
The utility model belongs to the technical field of the circulating water cooler among the power production, concretely relates to circulating water cooler back-flush device.
Background
At present, thermal power factory, oil system and cylinder steam extraction all use circulating water formula heat exchanger, circulating water formula heat exchanger water cycle flow is generally all with the water pump to the water source pump in the heat exchanger oil feed or low pressure cylinder steam extraction heat transfer, the water that has exchanged heat is pressed to the cooling tower, get into the water pump from the cooling tower and enter the heat transfer flow, because the cooling tower is uncovered, tower water is often by environmental pollution, often carry some silt particle or filler in the water and circulate, the time is just given stifled the water cycle flow to die, the washing flow only unpacks the heat exchanger apart and carries out the physics and wash or carry out chemical cleaning in the past.
The physical cleaning is usually to detach the end socket of the cooler and clean the water cooler by a high-pressure water gun, but the high-pressure water is used for washing to easily cause the vibration of the pipe, wear the pipe array and even break through the pipe, so that the service life of the cooler is seriously shortened, and therefore, the high-pressure water washing is only suitable for the short-time rapid treatment; chemical cleaning generally refers to cleaning the cooler with weak acid, weak base or detergent regularly, but these chemical agents are corrosive, and can corrode the cooler after long-term use, thus reducing the service life of the cooler.
The application of the back washing technology effectively prolongs the service life of the cooler, and the working principle is that the cooler is back washed by circulating water return water pressure after the cooler works for a certain time; however, the pressure of the circulating water inlet is generally larger than the pressure of the water outlet by nearly 0.2MPa, namely the circulating water return pressure is low, the washing effect is poor, scale and dirt with strong adhesive force cannot be washed away, and after the water is accumulated for a period of time, the heat exchange effect of the cooler can still be reduced, so that the service life of the cooler is reduced, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a circulating water cooler back flush circulating device, this circulating water cooler back flush circulating device have increased a set of inlet channel and outlet conduit who takes the control valve, when using back flush technique, can keep water inlet pressure to be greater than delivery port pressure all the time to it is good to have reached the cleaning performance, and the extension cooler life-span improves production efficiency's purpose.
The utility model provides a technical scheme that its technical problem adopted is: a backwashing device of a circulating water cooler comprises a normal water inlet and outlet pipeline component and a backwashing water inlet and outlet pipeline component which are arranged on the cooler, wherein the normal water inlet and outlet pipeline component comprises a normal water inlet pipe and a normal water outlet pipe; two ends of the back washing water inlet pipe are respectively connected to the front of the valves of the normal water inlet valve and the normal water outlet valve, and two ends of the back washing water outlet pipe are connected to the back of the valves of the normal water inlet valve and the normal water outlet valve.
Connect first blow-off pipe on the normal inlet tube, install first blow-off valve on the first blow-off pipe.
And a second blow-off pipe is connected to the normal water outlet pipe, and a second blow-off valve is installed on the second blow-off pipe.
The beneficial effects of the utility model are that, this circulating water cooler back flush circulating device utilizes the characteristics that the pressure of cooler inlet tube end water is greater than the pressure of water cooler outlet pipe end water, communicates the back flush inlet pipe subassembly and the back flush outlet pipe subassembly between the inlet tube and the outlet pipe of cooler to it is good to have a cleaning performance, and the extension cooler life-span improves production efficiency's beneficial effect.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a circulating water cooler back flush device, the device include install the normal water inlet and outlet pipeline subassembly and the back flush water inlet and outlet pipeline subassembly on cooler 7, normal water inlet and outlet pipeline subassembly includes normal inlet tube 8 and normal outlet pipe 11, install normal water intaking valve 1 and normal outlet valve 4 on normal inlet tube 8 and the normal outlet pipe 11 respectively, back flush water inlet and outlet pipeline subassembly includes back flush inlet tube 9 and back flush outlet pipe 10, back flush inlet tube 9 and back flush outlet pipe 10 are last to install back flush water intaking valve 2 and back flush outlet valve 3 respectively; two ends of the back washing water inlet pipe 9 are respectively connected in front of the valves of the normal water inlet valve 1 and the normal water outlet valve 4, and two ends of the back washing water outlet pipe 10 are connected behind the valves of the normal water inlet valve 1 and the normal water outlet valve 4.
Connect first blow off pipe 13 on the normal inlet tube 8, install first blowoff valve 6 on the first blow off pipe 13, connect second blow off pipe 12 on the normal outlet pipe 11, install second blowoff valve 5 on the second blow off pipe 12.
When the water cooler is used, when the cooler is quickly backwashed, the normal water inlet valve 1 and the normal water outlet valve 4 of the water circulation pipeline of the cooler are closed, the backwash water inlet valve 2 and the backwash water outlet valve 3 on the backwash pipeline are opened, and water enters the cooler from the water inlet pipe 8 through the backwash water inlet pipe 9 and then flows out from the backwash water outlet pipe 10.
Opening the first drain valve 6 to drain the washed dirty water, increasing the pressure and increasing the flow rate for washing, closing the back flush water inlet valve 2 and the back flush water outlet valve 3 on the back flush pipeline, opening the normal water inlet valve 1, the second drain valve 5 and closing the normal water outlet valve 4 for fast forward washing; the water cooling tower is cleaned while the cooler is cleaned by water, thereby preventing dirt in the water tower from causing vicious circle and increasing the times of cleaning the heat exchanger. In addition, a chemical cleaning agent can be added by utilizing the first sewage discharge valve 6 and the first sewage discharge valve 6 to perform chemical cleaning on the cooler, namely, the backwashing water inlet valve 2, the backwashing water outlet valve 3, the normal water inlet valve 1 and the normal water outlet valve 4 are closed, the first sewage discharge valve 6 and the second sewage discharge valve 5 of the water inlet and outlet valves are opened, and a pump is added to perform circulating cleaning.
