This paper describes a simulation test unit designed to enhance the dust removal performance in railway tunnels. The flow field inside the simulation test unit is investigated under different operating conditions through numerical simulations, and the variations in air volume and working resistance, total dust collection efficiency, and optimal operating parameters of a pulse cleaning system are identified through a series of experiments. The numerical results show that the pulse cleaning system does not significantly affect the uniformity of the flow field distribution at the bottom of the filter cartridge during the process of operation. The experimental research indicates that the simulation test unit satisfies the design requirements, achieving an average total dust removal efficiency of 99.93%. A field application shows that the total dust mass concentration at the operator position can be reduced from 335.8 mg\u2219m<jats:sup>\u22123<\/jats:sup> to 4.2 mg\u2219m<jats:sup>\u22123<\/jats:sup>, effectively improving the operating environment within the tunnel.<\/jats:p>","DOI":"10.1371\/journal.pone.0300192","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T16:09:26Z","timestamp":1712333366000},"page":"e0300192","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Research and application of bag filter system for railway ballast bed coal suction vehicles: An optimization and application study"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8858-5030","authenticated-orcid":true,"given":"Ke","family":"Lu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengjun","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongtai","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,4,5]]},"reference":[{"key":"pone.0300192.ref001","first-page":"11","article-title":"A study on the development strategies of railway coal transportation in China","volume":"38","author":"Y.
