A Cleaning of Internal Surfaces of Bunkers Without the Presence of Operating Personnel Inside the Bunker

Bunkers are an integral part of the infrastructure of enterprises in various industries processing bulk materials. Corrosion processes and the formation of dust deposits on the internal surfaces of bunkers are irreversible and often lead to disruptions in the technological process and equipment performance parameters, and in some cases, to accidents. The stability and continuity of technological processes for processing bulk materials largely depend on the cleanliness of the internal surfaces of bunkers. Even the best technical characteristics of technological equipment only indicate the technical capabili-ties of the operation of technological lines. Their reliable and effective operation can be ensured by proper maintenance of the condition of internal surfaces and cleaning from corrosion and deposits. Increased dustiness, poor visibility, and confined spaces significantly complicate the conditions for performing work by service personnel inside bunkers. The enclosed space inside bunkers is a very dangerous place not intended for the work of service personnel. In order to avoid endangering ser-vice personnel and prevent people from entering the bunker, methods are proposed to easily, quickly, and, most importantly, safely clean the surfaces inside the bunkers.
