Description

Technical Field

[0001] The invention relates to the field of steam, and in particular to a gas-fired steam fire control method and a transmission system. Background Art

[0002] With the increasing demand for steam in daily life and production, users are more and more in urgent need of energy-saving and intelligent steam. However, during use, due to the different usage of steaming equipment, the firepower and steaming time can only be adjusted and controlled manually, and corresponding adjustments need to be made according to actual usage needs. On the one hand, it causes a large workload for consumers and reduces work efficiency. On the other hand, due to the manual adjustment, the firepower adjustment control is not accurate enough, which easily leads to difficulty in controlling the steaming time of food, resulting in food being undercooked due to insufficient steam, or excessive steam causing food to be overcooked and steam wasted.

[0003] In addition, the steamer equipment requires high firepower, is not energy-saving, affects the environment and has no automation. The pressure cannot be controlled during the steam delivery process, and it is impossible to properly reduce the fuel supply and reduce the firepower, resulting in the release of excessive steam and energy waste. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0006] It is characterized by comprising the following steps:

[0007] S1: Open the steam outlet and the independent steam outlet or set the use time of the steam outlet through the timer;

[0008] S2: The intelligent automatic control system automatically starts the corresponding steam generator according to the corresponding steam output port and the independent steam output port;

[0009] S3: The intelligent automatic control system automatically obtains the real-time data of steam pressure and steam temperature at the steam output port and the gas flow rate at the gas inlet. Based on the real-time data of steam pressure, steam temperature and gas flow rate, it determines whether the current output steam is in a constant pressure state, and regularly samples and calculates the steam temperature, calculus dp1 and gas flow rate to ensure that the steam pressure value and steam temperature at the steam output port reach constant pressure and constant temperature.

[0010] S4: The independent steam outlet does not need to display the steam temperature, and the independent steam outlet only needs to maintain the state of being transported at the steam pressure P1. The steam is discharged from the steam generator and passes through the total steam output pipeline and the gas pipeline to reach the independent steam outlet. The steam outlet in the independent steam chamber needs to display the steam temperature. When the steam temperature does not reach the constant steam temperature T, the entire steam is output at the steam pressure P1. When the steam temperature reaches the constant steam temperature T, it is output at the steam pressure P0, P1>P0;

[0011] S5: When the independent steam outlet and steam outlet are all on, the intelligent automatic control system automatically 3 / h to supply and simultaneously open and ignite a corresponding number of steam generators. After normal operation, the intelligent automatic control system detects whether the gas is sufficient based on the real-time data of the gas flow meter. When the gas flow is insufficient, the intelligent automatic control system issues an alarm and increases the firepower level of the steam generator accordingly to ensure that the gas flow is within 2m 3 / h±0.2m 3 / h range.

[0012] S6: Within a certain period of time t1, when the steam temperature reaches the constant steam temperature T, the intelligent automatic control system detects that the steam pressure value at the steam outlet reaches the steam pressure P1. The intelligent automatic control system calculates the calculus dp1 according to the increase and decrease of the steam pressure. Assuming the current pressure is P2 and the time is t2, To calculate the value of dp1, and then dynamically adjust the firepower of the steam generator according to the value of dp1, to ensure that under the constant temperature state, the steam pressure of the output steam is maintained within the preset pressure range P, achieving a constant pressure state;

When the temperature has not reached the constant steam temperature T, the system works at the steam pressure P1. When all temperatures reach the constant steam temperature T, the intelligent automatic control system will decide how much to reduce the firepower level according to the numerical value of △P=P1-P0.

When there is a special pressure increase to 0.15MPa, the intelligent automatic control system will automatically shut down the steam generator.

[0015] As a further solution of the present invention: when the calculated numerical range of dp1 is greater than zero and less than 0.5, the firepower gear of the steam generator is kept unchanged, and the preset pressure range P is kept between 0.07 MPa and 0.1 MPa; when the calculated numerical range of dp1 is greater than 0.5 and less than 1, the firepower gear of the steam generator should be reduced, and the intelligent automatic control system will decide how much to reduce the firepower gear according to the numerical value of △P, and control the preset pressure range P between 0.07 MPa and 0.1 MPa; when the calculated numerical range of dp1 is less than 0, the firepower gear of the steam generator should be increased, and the intelligent automatic control system will decide how much to increase the firepower gear of the steam generator according to the numerical value of △P, and control the preset pressure range P between 0.07 MPa and 0.1 MPa.

[0016] As a further solution of the present invention: when receiving the closing instruction, the intelligent automatic control system stops inputting steam to the steam output port, and the steam generator is also closed accordingly, and the intelligent automatic control system delays closing one of the steam output ports to achieve the purpose of relieving pressure.

[0017] As a further solution of the present invention: the constant steam temperature T is 100°C.

[0018] As a further solution of the present invention: a water inlet and a gas inlet are provided on one side of the steam generator, a gas flow meter is installed on the gas inlet, and a signal output end of the gas flow meter is communicatively connected to a signal input end of the intelligent automatic control system.

[0019] As a further solution of the present invention: the output ends of the temperature sensing unit and the temperature probe are communicatively connected to the signal input end of the intelligent automatic control system.

[0020] As a further solution of the present invention: the steam generator includes a pulse igniter, a fire grate burner and a gas electromagnetic switch valve, the output end of the pulse igniter is communicated with the signal input end of the fire grate burner, one side of the gas electromagnetic switch valve is connected to the gas inlet, the fire grate burner is connected to the gas inlet through the gas electromagnetic switch valve, the controlled end of the pulse igniter is communicated with the signal output end of the intelligent automatic control system, the signal output end of the intelligent automatic control system is connected to a relay switch, and the output end of the relay switch is communicated with the pulse igniter.

[0037] A gas-fired steam fire control method, characterized in that it comprises the following steps:

[0038] S1: Open the steam outlet 112 and the independent steam outlet 5 or set the use time of the steam outlet 112 by a timer;

[0039] S2: The intelligent automatic control system 2 automatically starts the corresponding steam generator 4 according to the corresponding steam output port 112 and the independent steam output port 5;

[0040] S3: The intelligent automatic control system 2 automatically obtains the real-time data of steam pressure and steam temperature at the steam output port 112 and the gas flow rate at the gas inlet, and judges whether the current output steam is in a constant pressure state according to the real-time data of steam pressure, steam temperature and gas flow rate, and regularly samples and calculates the steam temperature, calculus dp1 and gas flow rate to ensure that the steam pressure value and steam temperature of the steam output port 112 reach constant pressure and constant temperature;

[0041] S4: The independent steam output port 5 does not need to display the steam temperature, and the independent steam output port 5 only needs to maintain the state of being transported at the steam pressure P1. The steam is discharged from the steam generator 4 and passes through the total steam output pipeline 3 and the gas pipeline 32 to reach the independent steam output port 5, while the steam output port 112 in the independent steam chamber 1 needs to display the steam temperature. When the steam temperature does not reach the constant steam temperature T, the entire steam is output at the steam pressure P1. When the steam temperature reaches the constant steam temperature T, it is output at the steam pressure P0 (P1>P0);

[0042] S5: When the independent steam outlet 5 and the steam outlet 112 are all on, the intelligent automatic control system 2 automatically starts at a gas flow rate of 2m 3 / h is supplied and the corresponding number of steam generators 4 are turned on and ignited at the same time. After normal operation, the intelligent automatic control system 2 detects whether the gas is sufficient according to the real-time data of the gas flow meter 46. When the gas flow is insufficient, the intelligent automatic control system 2 issues an alarm and increases the fire level of the steam generator 4 accordingly to ensure that the gas flow is within 2m 3 / h±0.2m 3 / h range.

[0043] S6: Within a certain period of time t1, when the steam temperature reaches the constant steam temperature T, the intelligent automatic control system 2 detects that the steam pressure value of the steam output port 112 reaches the steam pressure P1, and the intelligent automatic control system 2 calculates the calculus dp1 according to the increase and decrease of the steam pressure. Assuming that the current pressure is P2 and the time is t2, The value of dp1 is calculated, and then the firepower of the steam generator 4 is dynamically adjusted according to the value of dp1 to ensure that the steam pressure of the output steam is maintained within the preset pressure range P under the constant temperature state, thus achieving a constant pressure state;

[0044] S7: Within a certain period of time t1, when the steam temperature reaches the constant steam temperature T, when the intelligent automatic control system 2 detects that the pressure of the steam input pipe 111 does not reach the steam pressure P1, it can be determined that there is insufficient gas. The intelligent automatic control system 2 will increase the firepower level of the steam generator 4 while issuing a voice alarm. The increased firepower level of the steam generator 4 is determined by the difference between the current steam pressure P3 and the initial steam pressure P1, that is, △P=P1-P3, ensuring that under a constant temperature state, the steam pressure of the output steam is maintained within the preset pressure range P to achieve a constant pressure state. When the temperature has not reached the constant steam temperature T, the system operates at the steam pressure P1. When all temperatures reach the constant steam temperature T, the intelligent automatic control system 2 will decide how much to reduce the firepower level according to the numerical value of △P=P1-P0. When the pressure drops to near P0, the calculus algorithm is used to control the steam pressure to be near the preset pressure range P.

[0045] The preset pressure range of the steam pressure is P=P1±PX (or P=P0±PX), and the value range of P is 0.07 MPa~0.1 MPa. When there is a special pressure increase to 0.15 MPa, the intelligent automatic control system 2 will automatically shut down the steam generator.

[0046] When the calculated numerical range of dp1 is greater than zero but less than 0.5, the firepower level of the steam generator 4 is kept unchanged, and the preset pressure range P is kept between 0.07 MPa and 0.1 MPa. When the calculated numerical range of dp1 is greater than 0.5 but less than 1, the firepower level of the steam generator 4 should be reduced, and the intelligent automatic control system 2 will decide how much to reduce the firepower level according to the numerical value of △P, and control the preset pressure range P between 0.07 MPa and 0.1 MPa. When the calculated numerical range of dp1 is less than 0, the firepower level of the steam generator 4 should be increased, and the intelligent automatic control system 2 will decide how much to increase the firepower level of the steam generator according to the numerical value of △P, and control the preset pressure range P between 0.07 MPa and 0.1 MPa.

[0047] When receiving the closing instruction, the intelligent automatic control system 2 stops inputting steam to the steam output port 112, and the steam generator 4 is also closed accordingly, and the intelligent automatic control system 2 delays closing one of the steam output ports 112 to achieve the purpose of relieving pressure.

When all temperatures reach the constant steam temperature T, the calculus algorithm is used to control the steam pressure to be near the preset pressure range P. Therefore, when the calculated value range of dp1 is greater than 0 and less than 0.5, the firepower gear of the steam generator 4 is kept unchanged and kept within the preset pressure range P. The intelligent automatic control system 2 dynamically adjusts the firepower of the steam generator 4 according to the value of dp1 to ensure that under the constant temperature, the steam pressure of the output steam is maintained within the preset pressure range P to achieve a constant pressure state.

Within time t1, when the steam temperature reaches the constant steam temperature T, the intelligent automatic control system 2 detects that the pressure of the steam input pipe 111 does not reach the steam pressure P1, then it can be judged Due to insufficient gas, the intelligent automatic control system 2 calculates the calculus dp1 according to the increase and decrease of the steam pressure. When the calculated dp1 has a numerical range less than 0, the firepower level of the steam generator 4 should be increased. The intelligent automatic control system 2 will decide how much to increase the firepower level of the steam generator according to the numerical value of △P. The increased firepower level of the steam generator 4 is determined by the difference between the current steam pressure P3 and the initial steam pressure P1, that is, △P=P1-P3, ensuring that under a constant temperature state, the steam pressure of the output steam is maintained within the preset pressure range P to achieve a constant pressure state.

[0051] Embodiment 3: The intelligent automatic control system 2 automatically obtains the real-time data of steam pressure and steam temperature at the steam output port 112, and determines whether the current output steam is in a constant pressure state according to the real-time data of steam pressure and steam temperature, and regularly samples and calculates the steam temperature and calculus dp1 to ensure that the steam pressure value and steam temperature of the steam output port 112 reach constant pressure and constant temperature. When all temperatures reach the constant steam temperature T, the calculus algorithm is used to control the steam pressure to be near the preset pressure range P. When the calculated value range of dp1 is greater than 0.5 and less than 1, the firepower level of the steam generator 4 should be reduced. The intelligent automatic control system 2 will decide how much to reduce the firepower level according to the value of △P, and control the preset pressure range P to reach a constant pressure state.

Assuming the current pressure is P2 and the time is t2, To calculate the value of dp1, and then dynamically adjust the firepower of the steam generator according to the value of dp1, to ensure that under the constant temperature state, the steam pressure of the output steam is maintained within the preset pressure range P, achieving a constant pressure state; S7: Within a certain period of time t1, when the steam temperature reaches the constant steam temperature T, when the intelligent automatic control system detects that the pressure of the steam input pipeline does not reach the steam pressure P1, it is judged that there is insufficient gas. The intelligent automatic control system will increase the firepower level of the steam generator while issuing a voice alarm. The increased firepower level of the steam generator is determined by the difference between the current steam pressure P3 and the initial steam pressure P1, that is, △P=P1-P3, to ensure that under a constant temperature state, the steam pressure of the output steam is maintained within the preset pressure range P to achieve a constant pressure state. When the temperature has not reached the constant steam temperature T, the system works at the steam pressure P1. When all temperatures reach the constant steam temperature T, the intelligent automatic control system will decide how much to reduce the firepower level according to the value of △P=P1-P0. When the pressure drops to near P0, the calculus algorithm is used to control the steam pressure to be near the preset pressure range P.

6. The control method according to claim 5, characterized in that: The preset pressure range of the steam pressure is P=P1±PX, or P=P0±PX, and the value range of P is 0.07 MPa~0.1 MPa. When there is a special pressure increase to 0.15 MPa, the intelligent automatic control system will automatically shut down the steam generator.

7. The control method according to claim 5, characterized in that: When the calculated dp1 value range is greater than zero but less than 0.5, the firepower level of the steam generator is kept unchanged, and the preset pressure range P is kept between 0.07 MPa and 0.1 MPa. When the calculated dp1 value range is greater than 0.5 but less than 1, the firepower level of the steam generator should be reduced. The intelligent automatic control system will decide how much to reduce the firepower level according to the value of △P, and the preset pressure range P is controlled between 0.07 MPa and 0.1 MPa. When the calculated dp1 value range is less than 0, the firepower level of the steam generator should be increased. The intelligent automatic control system will decide how much to increase the firepower level of the steam generator according to the value of △P, and the preset pressure range P is controlled between 0.07 MPa and 0.1 MPa.

8. The control method according to claim 5, characterized in that: When receiving the closing instruction, the intelligent automatic control system stops inputting steam to the steam output port, and the steam generator is also closed accordingly, and the intelligent automatic control system delays closing one of the steam output ports to achieve the purpose of relieving pressure.

9. The control method according to claim 5, characterized in that: The constant steam temperature T is 100°C.
