Description

Technical Field

[0001] This application relates to the field of condenser cleaning technology, and in particular to an escape prevention system and control method for descaling pipes with rubber balls. Background Technology

[0002] Although most thermal power plants in China are currently equipped with condenser ball cleaning systems, their operation is generally poor, resulting in condenser heat exchange efficiency that falls short of expectations and extremely low ball recovery rates. Due to the malfunction of these systems, some power plants have temporarily abandoned them or are operating them with minimal efficiency; this directly impacts condenser cleanliness, thereby reducing the economic efficiency of the unit operation.

[0003] In current cleaning systems, the rubber balls are prone to contacting the rotor of the rubber ball pump during continuous circulation, causing them to break and become damaged. Simultaneously, the narrow, square channel design of the "A"-shaped ball-collecting net makes it easy for rubber balls to get stuck, escaping into the main water pipe after the collecting blades move. Excessive ball escape not only affects cleaning efficiency but also necessitates constant replenishment, increasing operating costs and causing environmental pollution, such as clogging the packing material in the circulating water cooling tower. Summary of the Invention

[0004] The purpose of this application is to provide an anti-escape system and control method for descaling pipes with rubber balls in order to solve the above-mentioned technical problems, thereby achieving zero escape of the rubber balls and improving the ball collection rate.

[0006] In some embodiments of this application, a first ball-collecting net and a second ball-collecting net are added, and a drum-type filter screen design is adopted.

At the same time, as the number of rubber balls on the second ball-collecting net increases, the tilt angle of the first ball-collecting net is increased. At this time, the first ball-collecting net can also intercept the rubber balls, preventing them from escaping. Meanwhile, the open area of ​​the filter screen is 3 to 5 times the cross-sectional area of ​​the circulating water pipe, which can ensure that the rubber balls, packing, and debris are not stuck or blocked, and there is no pressure difference change before and after the filter screen, ensuring flow.

[0044] In some embodiments of this application, an escape prevention system for descaling with rubber balls in pipelines is provided, comprising: a circulating water pipeline, a ball loading chamber, and a rubber ball pump;

[0045] A ball collecting section is installed inside the circulating water pipe. The ball collecting section is connected to the ball pump and is used to collect the balls inside the circulating water pipe.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0064] As Figure 1 shown, a control method for an anti-escape system for pipeline rubber ball descaling in a preferred embodiment of an embodiment of the present application includes:

[0065] S101: Obtain the number of rubber balls put in, set the ball collection time interval according to the number of rubber balls put in, and correct the next ball collection time interval according to the actual number of balls collected in real time;

[0066] S102: Set the initial inclination angle of the first ball collection net according to the number of rubber balls put in, and correct the inclination angle of the first ball collection net according to the actual number of balls collected by the second ball collection net in real time.

[0067] Specifically, when setting the ball collection time interval according to the number of rubber balls put in, it includes:

[0068] Preset a rubber ball quantity matrix A, set A(A1, A2, A3, A4), where A1 is the preset first rubber ball quantity, A2 is the preset second rubber ball quantity, A3 is the preset third rubber ball quantity, A4 is the preset fourth rubber ball quantity, and A1 < A2 < A3 < A4;

[0069] Preset a ball collection time interval matrix T, set T(T1, T2, T3, T4), where T1 is the preset first ball collection time interval, T2 is the preset second ball collection time interval, T3 is the preset third ball collection time interval, T4 is the preset fourth ball collection time interval, and T1 < T2 < T3 < T4;

[0070] Set the actual ball collection time interval t according to the actual number of rubber balls a put in;

[0071] If A1 < a < A2, set the actual ball collection time interval t as the preset fourth ball collection time interval T4, that is, t = T4;

[0072] If A2 < a < A3, set the actual ball collection time interval t as the preset third ball collection time interval T3, that is, t = T3;

[0073] If A3 < a < A4, set the actual ball collection time interval t as the preset second ball collection time interval T2, that is, t = T2;

[0074] If a > A4, set the real-time ball collection time interval t as the preset first ball collection time interval T1, that is, t = T1.

[0075] It can be understood that in the above embodiments, by adding a rubber ball quantity matrix and a ball collection time interval matrix, setting the circulating ball collection time according to the initial rubber ball quantity put in, and recycling the rubber balls in the circulating water pipeline in time, the rubber balls can be prevented from escaping and the operation cost can be reduced.

[0076] In the preferred embodiment of the embodiment of the present application, when correcting the next ball collection time interval according to the real-time ball collection quantity, it includes:

[0077] Obtain the ball collection quantity of the first ball collection net and the ball collection quantity of the second ball collection net, generate the total ball collection quantity c, set the time interval correction coefficient n according to the total ball collection quantity c, and correct the next ball collection time interval t1.

[0078] Specifically, when setting the time interval correction coefficient n according to the total ball collection quantity c, it includes:

[0079] Preset a time interval correction coefficient matrix N, set N(n1, n2, n3, n4), where n1 is the preset first time interval correction coefficient, n2 is the preset second time interval correction coefficient, n3 is the preset third time interval correction coefficient, n4 is the preset fourth time interval correction coefficient, and n1 < n2 < n3 < n4 < 1;

[0080] Preset a total ball collection quantity matrix C, set C(C1, C2, C3, C4), where C1 is the preset first total ball collection quantity, C2 is the preset second total ball collection quantity, C3 is the preset third total ball collection quantity, C4 is the preset fourth total ball collection quantity, and C1 < C2 < C3 < C4;

[0081] If C1 < c < C2, set the time interval correction coefficient n = n4, and the corrected next ball collection time interval t1 = n4 Ti (i = 1, 2, 3, 4);

[0082] If C2 < c < C3, set the time interval correction coefficient n = n3, and the corrected next ball collection time interval t1 = n3 Ti (i = 1, 2, 3, 4);

[0083] If C3 < c < C4, set the time interval correction coefficient n = n2, and the corrected next ball collection time interval t1 = n2 Ti (i = 1, 2, 3, 4);

[0084] If c > C4, set the time interval correction coefficient n = n1, and the corrected next ball collection time interval t1 = n1 Ti (i = 1, 2, 3, 4).

[0085] It is understandable that in the above embodiments, by presetting the time interval correction coefficient, and by obtaining the amount of balls collected by the ball collection net at each ball collection time node, the ball collection time is adjusted in a timely manner, the ball collection interval is dynamically adjusted, and the rubber balls in the circulating water pipeline are recovered in a timely manner, so as to avoid a large amount of rubber balls accumulating at the ball collection net and affecting the circulation of the circulating water.

[0086] In a preferred embodiment of the embodiments of the present application, when setting the initial inclination angle of the first ball collection net according to the number of rubber balls put in, it includes:

[0087] Preset a ball collection net inclination angle matrix D, set D(D1, D2, D3, D4), where D1 is the preset initial inclination angle of the first ball collection net, D2 is the preset initial inclination angle of the second ball collection net, D3 is the preset initial inclination angle of the third ball collection net, D4 is the preset initial inclination angle of the fourth ball collection net, and D1 < D2 < D3 < D4;

[0088] Set the real-time inclination angle d of the first ball collection net for receiving balls according to the real-time number a of rubber balls put in;

[0089] If A1 < a < A2, set the real-time inclination angle d of the first ball collection net for receiving balls as the preset initial inclination angle D1 of the first ball collection net, that is, d = D1;

[0090] If A2 < a < A3, set the real-time inclination angle d of the first ball collection net for receiving balls as the preset initial inclination angle D2 of the second ball collection net, that is, d = D2;

[0091] If A3 < a < A4, set the real-time inclination angle d of the first ball collection net for receiving balls as the preset initial inclination angle D3 of the third ball collection net, that is, d = D3;

[0092] If a > A4, set the real-time inclination angle d of the first ball collection net for receiving balls as the preset initial inclination angle D4 of the fourth ball collection net, that is, d = D4.

[0093] Specifically, the inclination angle of the first ball collection net is set according to the initial number of rubber balls put in. In this process, the collection ability of the first ball collection net gradually increases. The more the initial number of rubber balls put in, the more rubber balls may enter the circulating water pipeline, and the more rubber balls the second ball collection net needs to intercept. By adjusting the inclination angle of the first ball collection net, the operating burden of the second ball collection net is reduced, and rubber ball escape is avoided.

[0094] Specifically, when correcting the inclination angle of the first ball collection net according to the real-time ball collection quantity of the second ball collection net, it includes:

[0095] Obtain the total weight data of the rubber balls on the second ball collection net and generate the real-time ball collection quantity e of the second ball collection net;

[0096] Set an inclination angle correction coefficient m according to the real-time ball collection quantity e of the second ball collection net and correct the real-time inclination angle d1 of the first ball collection net.

[0097] Specifically, when setting the tilt angle correction coefficient m according to the real-time ball collection quantity e of the second ball collection net, it includes:

[0098] Preset a ball collection quantity matrix E of the ball collection net, set E(E1, E2, E3, E4), where E1 is the preset ball collection quantity of the first ball collection net, E2 is the preset ball collection quantity of the second ball collection net, E3 is the preset ball collection quantity of the third ball collection net, E4 is the preset ball collection quantity of the fourth ball collection net, and E1 < E2 < E3 < E4;

[0099] Preset a tilt angle correction coefficient matrix M, set M(m1, m2, m3, m4), where m1 is the preset first tilt angle correction coefficient, m2 is the preset second tilt angle correction coefficient, m3 is the preset third tilt angle correction coefficient, m4 is the preset fourth tilt angle correction coefficient, and 1 < m1 < m2 < m3 < m4;

[0100] If E1 < e < E2, set m = m1, and the real-time tilt angle d1 of the first ball collection net after correction is m1 d;

[0101] If E2 < e < E3, set m = m2, and the real-time tilt angle d1 of the first ball collection net after correction is m2 d;

[0102] If E3 < e < E4, set m = m3, and the real-time tilt angle d1 of the first ball collection net after correction is m3 d;

[0103] If e > E4, set m = m4, and the real-time tilt angle d1 of the first ball collection net after correction is m4 d.

[0104] It can be understood that in the above embodiments, in the initial state, the rubber balls can run through, enter the second ball collection net. A large number of mesh holes are also provided on the second ball collection net, but the diameter is 10 mm, which can intercept and collect the rubber balls. At the same time, as the number of rubber balls on the second ball collection net increases, the tilt angle of the first ball collection net is increased. At this time, the first ball collection net can also intercept the rubber balls, and the interception ability gradually increases, avoiding the escape of rubber balls. At the same time, the open area of the filter screen is 3 to 5 times the cross-sectional area of the circulating water pipe, which can ensure that the rubber balls, fillers, and garbage are not stuck or blocked, and there is no pressure difference change before and after the filter screen, ensuring smooth flow.

[0105] As Figure 2 shown, based on another preferred embodiment of the control method of an anti-escape system for pipeline rubber ball scale removal in any one of the above preferred embodiments, in this embodiment, an anti-escape system for pipeline rubber ball scale removal is provided, including: a circulating water pipeline 200, a ball loading chamber 100, and a rubber ball pump 300, and is characterized by including:

[0106] The ball collecting section is located inside the circulating water pipe 200 and is connected to the ball pump 300. The ball collecting section is used to collect the balls inside the circulating water pipe 200.

[0107] The rubber balls collected in the circulating water pipe 200 by the ball receiving section enter the ball loading chamber 100 through the rubber ball pump 300;

[0108] The control unit is used to obtain the number of rubber balls thrown in, and to set the ball collection time interval based on the number of rubber balls thrown in.

[0109] Specifically, the rubber balls collected in the circulating water pipe 200 in the ball receiving section can be recycled back into the ball loading chamber 100 through the recycling pipe and ball valve 600 by the rubber ball pump 300, thus realizing the recycling of the rubber balls.

[0110] Specifically, the ball receiving section includes:

[0111] A first ball-collecting net 400 is installed inside the circulating water pipe 200. The first ball-collecting net 400 has a first through-hole structure and is used to collect rubber balls inside the circulating water pipe 200.

[0112] The second ball-collecting net 500 is installed inside the circulating water pipe 200. The second ball-collecting net 500 is positioned opposite to the first ball-collecting net 400. The second ball-collecting net 500 is provided with a second through-hole structure. The second ball-collecting net 500 is used to collect the rubber balls inside the circulating water pipe 200.

[0113] Multiple sensors are installed on the second ball-collecting net 500, which are used to collect the total weight of the balls on the second ball-collecting net 500.

[0114] Specifically, the first through-hole structure has multiple through holes, the diameter of which is larger than the diameter of the rubber ball. In the initial state, the rubber ball can pass through the through holes and pass through the first ball-collecting net 400. By adjusting the tilt angle of the first ball-collecting net 400, the rubber ball can be intercepted.

[0115] Specifically, the second through-hole structure consists of two through-holes with a diameter of 10mm to ensure that the rubber balls, fillers, and debris are not stuck or blocked, and that there is no pressure difference change before and after the filter screen, thus ensuring flow.

[0116] Specifically, the ball receiving section also includes:

[0117] A rotating structure is connected to the first ball-collecting net 400, and the rotating structure is used to control the tilt angle of the first ball-collecting net 400.

[0118] According to the first concept of this application, by adding a control unit, the ball collection time interval is set according to the real-time number of balls thrown, so as to realize the automatic and timely collection of balls, reduce the workload of manual labor, and at the same time, by obtaining the ball collection amount of the ball collection net, the ball collection time can be adjusted in time to avoid the accumulation of a large number of balls at the ball collection net, which would affect the circulation of circulating water.

[0119] According to the second concept of this application, by adding a first ball-collecting net and a second ball-collecting net, a drum-type filter screen design is adopted. The first ball-collecting net has a large number of mesh holes, which allow rubber balls to pass through in the initial state and enter the second ball-collecting net. The second ball-collecting net also has a large number of mesh holes, but the diameter is 10mm, which can intercept and collect the rubber balls. At the same time, as the number of rubber balls on the second ball-collecting net increases, the tilt angle of the first ball-collecting net is increased. At this time, the first ball-collecting net can also intercept the rubber balls and prevent them from escaping. Meanwhile, the open area of ​​the filter screen is 3 to 5 times the cross-sectional area of ​​the circulating water pipe, which can ensure that rubber balls, packing, and debris are not stuck or blocked, and there is no pressure difference change before and after the filter screen, ensuring flow.

[0120] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
