Abstract

The invention provides a device and a method for hydraulically cleaning a sediment tank. The device for hydraulically cleaning the sediment tank comprises a tank body, wherein a cleaning fluid spraying units and a cleaning fluid distribution unit are arranged in the tank body, and a cleaning fluid conveying mechanism is arranged outside the tank body; the cleaning fluid distribution unit involvesan annular pipe and a fixing device, a plurality of cleaning fluid feeding holes are formed in the annular pipe, and flange holes used for the cleaning fluid spraying units to be mounted are connectedto the cleaning fluid feeding holes; and the cleaning fluid conveying mechanism comprises a booster pump and a conveying pipeline, a cleaning fluid feeding opening is formed in the side face of a barrel, the cleaning fluid feeding opening is externally connected with the conveying pipeline, and the cleaning fluid feeding opening communicates with the annular pipe. The method for hydraulically cleaning the sediment tank comprises the following steps of pumping cleaning fluid into the cleaning fluid distribution unit to annularly distribute the cleaning fluid in the sediment tank, and then uniformly distributing the cleaning fluid to the cleaning fluid spraying units to clean the bottom of the sediment tank. The device and the method are simple in structure, low in cost, convenient to operate and effective in washing of high-viscosity solid sludge, and manpower and material resources are saved.

Description

technical field [0001] The patent of the invention belongs to the field of chemical equipment, and specifically relates to a sediment tank cleaning device and method. Background technique [0002] At present, in the chemical industry, sedimentation tanks are widely used in the entire chemical production line, and many reactors, settling tanks, and tower equipment will generate reaction residues, so the cleaning of sedimentation tanks is particularly important. The size of the sediment tank is different according to the different feeding amount and different process requirements. For the sediment tank with a large volume, manual cleaning is used when cleaning, which is time-consuming, labor-intensive, and labor-intensive. When the reaction involves toxic and harmful substances , causing harm to cleaning personnel, and when high-viscosity solid sludge is produced in the sediment tank, it will cause cleaning difficulties during shutdown for maintenance or slag discharge, especi...
