Abstract

An online cleaning device for a heat exchanger with oily dirt, mainly composed of a cleaning agent storage tank (1), a hot oil pump a (2), a hot oil pump b (3), a cleaning agent heating device (4), and a steel wire pressurized hose (5) and heat exchanger (6), the components of the above-mentioned main structure pass through flange joints (11), tee joints (12), ball valves (13), reducing joints (14) and steel wire pressurized hoses (5) and other components are connected into a cleaning device capable of stable operation and recycling, wherein the cleaning agent heating device (4) is a welded box structure, and is provided with a steam heating coil (41), a filter plate (42), Sewage cleaning hole (43), sewage pipe (44) and removable transparent case cover (47). The invention has simple and practical structure, low cost, avoids the disassembly and transportation of the heat exchanger, can be cleaned at the production site, and multiple devices can be cleaned at the same time in a cycle loop, convenient and flexible to use, and easy to clean oil-soluble dirt The main component of the agent is an organic solvent, which can be reused after being circulated and filtered. It has good energy saving benefits, no pollution to the environment, and has broad market prospects.

Description

technical field [0001] The invention relates to cleaning of equipment in the chemical industry, in particular to a cleaning device for heat exchangers in oil refineries and the like in the petrochemical industry. Background technique [0002] Heat exchanger is the most commonly used equipment in petroleum processing units, and its investment accounts for about 70% of the total investment in the chemical industry and 35-40% in the refining industry. To measure the pros and cons of a heat exchanger’s operation, in addition to its inherent equipment characteristics and process conditions, how to ensure the cleanliness of its medium heat exchange surface, ensure a good heat conduction space and total heat transfer effect is an important factor. [0003] The research data of the Harwell Laboratory in the United Kingdom shows that the maintenance cost caused by the heat exchanger accounts for 15% of the total maintenance cost, half of which is caused by fouling. Scaling on the su...
