Embodiments herein relate to filtration systems that can pulse clean filter elements selectively, in specific patterns, to enhance cleaning efficacy. In an embodiment, a filtration system is included having a plurality of filter element mounts configured to retain filter elements, a compressed gas supply, and a plurality of valves in fluid communication with the compressed gas supply. The system further including a control circuit configured to control actuation of the plurality of valves. The system can operate in a first mode and a second mode. Wherein operating in a first mode includes opening valves according to a first valve actuation pattern and operating in a second mode includes opening valves according to a second valve actuation pattern. The system can be configured to periodically switch from the first mode to the second mode and compare the efficacy of the two modes. Other embodiments are also included herein.
A filtration system comprising:
The filtration system of any of claims 1 and 3-20, wherein the first mode represents a default operating mode.
The filtration system of any of claims 1-2 and 4-20, wherein the control circuit selects the second valve actuation pattern of the second mode from amongst a set of preconfigured valve actuation patterns.
The filtration system of any of claims 1-3 and 5-20, wherein the control circuit selects the second valve actuation pattern of the second mode based on factors including temporal factors.
The filtration system of any of claims 1-4 and 6-20, wherein the control circuit selects the second valve actuation pattern of the second mode based on a pattern matching algorithm.
The filtration system of any of claims 1-5 and 7-20, wherein the control circuit is configured to generate new valve actuation patterns by modifying parameters of existing valve actuation patterns.
The filtration system of any of claims 1-6 and 8-20, wherein the control circuit is configured to store generated valve actuation patterns as a part of a set of preconfigured valve actuation patterns.
The filtration system of any of claims 1-7 and 9-20, wherein the control circuit receives the second valve actuation pattern from a remote site.
The filtration system of any of claims 1-8 and 10-20, wherein the filtration system receives one or more valve actuation patterns from a remote site.
The filtration system of any of claims 1-9 and 11-20, wherein opening the plurality of valves results in a pulse of a gas directed at the filter element.
The filtration system of any of claims 1-10 and 12-20, wherein the plurality of valves are arrayed in a grid pattern.
The filtration system of any of claims 1-11 and 13-20, wherein the efficacy is assessed based on a magnitude of a change in pressure drop in the filtration system achieved resulting from execution of a valve actuation pattern.
The filtration system of any of claims 1-12 and 14-20, wherein the efficacy is assessed based on a magnitude of pressure drop recovery in the filtration system achieved resulting from execution of a valve actuation pattern.
The filtration system of any of claims 1-13 and 15-20, wherein the efficacy is assessed based on a magnitude of sustained pressure drop recovery in the filtration system achieved resulting from execution of a valve actuation pattern.
The filtration system of any of claims 1-14 and 16-20, wherein the efficacy is assessed based on a magnitude of a change in velocity across a filter element achieved resulting from execution of a valve actuation pattern.
The filtration system of any of claims 1-15 and 17-20, wherein the control circuit adopts the second mode as a new default mode if the efficacy of the second mode is better than the efficacy of the first mode.
The filtration system of any of claims 1-16 and 18-20, wherein the second valve actuation pattern is different than the first valve actuation pattern in at least one operational parameter.
The filtration system of any of claims 1-17 and 19-20, wherein the operational parameters are selected from the group consisting of a horizontal actuation sequence, a vertical actuation sequence, a zone actuation sequence, a linked group actuation sequence, a valve opening time, an amount of time between sequential valve actuations, and a threshold pressure drop for triggering valve actuation.
The filtration system of any of claims 1-18 and 20, wherein the control circuit is configured to trigger actuation of at least one other treatment in combination with valve actuation patterns.
A filtration system comprising:
