Embodiment 1

[0058] like figure 1 As shown, the specific steps of the method include:

[0059] S1, based on pre-configured data filtering rules, filtering the received nitrogen oxide concentration data;

[0060] S2, carry out positive control on the effective data obtained after filtering, and determine the reference value of the ammonia injection amount currently participating in the control;

[0061] S3, perform reverse control on the effective data obtained after filtering, and determine the adjustment value of the ammonia injection amount currently participating in the control;

[0062] S4. Determine the ammonia injection value at the next moment according to the reference value and the adjustment value, and set the action time. When the time is up, continue to update the ammonia injection value according to the calculated reference value and adjustment value.

[0063] The nitrogen oxide concentration data in step S1 includes: inlet nitrogen oxide data, ammonia injection amount data,...

Embodiment 2

[0077] Based on the same inventive concept, the present invention also provides an optimized automatic control system for industrial enterprises to discharge pollution, which is characterized in that it includes:

[0078] A filtering module, configured to filter the received nitrogen oxide concentration data based on pre-configured data filtering rules;

[0079] The first control module is used to perform forward control on the effective data obtained after filtering, and determine the reference value of the ammonia injection amount currently participating in the control;

[0080] The second adjustment module is used to reversely control the effective data obtained after filtering, and determine the adjustment value of the ammonia injection amount currently participating in the control;

[0081] Among them, the filtering module includes:

[0082] The comparison module is used to compare the size between the inlet nitrogen oxide data, the ammonia injection data, the outlet nit...

Abstract

The invention discloses an optimized self-control method and a system for industrial enterprise emission pollution, and the method comprises the steps: filtering received nitrogen oxide concentration data at an inlet based on a pre-configured data filtering rule, carrying out the forward control of effective data obtained after filtering, and determining a reference value which participates in the control of the ammonia spraying amount at present; based on a pre-configured data filtering rule, filtering the received nitrogen oxide concentration data at the outlet, performing reverse control on effective data obtained after filtering, and determining an adjustment value currently participating in control of the ammonia spraying amount; and determining the ammonia spraying value at the next moment according to the reference value of the ammonia spraying amount and the adjusting value given by an anti-control system. According to the scheme, the ammonia spraying amount is automatically controlled and adjusted from the data level, it is guaranteed that nitric oxide at an outlet does not exceed a set value, and meanwhile a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of ammonia injection control, in particular to an optimized self-control method and system for industrial enterprises to discharge pollution. Background technique [0002] At present, industrial enterprises at home and abroad often use the method of artificially adding ammonia injection to control the concentration of nitrogen oxides at the outlet. dosage. [0003] However, the existing method of artificially adding ammonia injection not only requires a lot of manpower, but also leads to waste of liquid ammonia and excessive nitrogen oxides in exports due to the inability to accurately control artificially. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an ammonia injection automatic control method and system for industrial enterprises to discharge nitrogen oxides exceeding the standard, which can effectively control the nitrogen oxides of...
