Description
Technical field
The present invention relates to the Chemical cleaning of the equipment such as condenser, heat exchanger.
Background technology
Condenser equipment is an important component part of Steam Turbine, and its service behaviour directly affects the security of whole Steam Turbine, reliability, stability and economy.And condenser vacuum is the important indicator of steam turbine operation, also be a main performance assessment criteria of reflection condenser combination property, the too low meeting of condenser vacuum has a strong impact on the safety and economic operation of Power Plant, and cause condenser vacuum too low major reason is exactly Cooling Tubes of Condenser fouling.So periodic cleaning Cooling Tubes of Condenser is the prerequisite ensureing that condenser and Steam Turbine normally work.
The conventional cleaning way of condenser is divided into physical cleaning and Chemical cleaning two kinds, and physical cleaning mode is progressively replaced by Chemical cleaning mode because of shortcomings such as its descaling rate are not high, scavenging period is long, and the mechanical damage of high pressure to Cooling Tubes of Condenser is serious.The Chemical cleaning mode used at present, normally first seal intake chamber and the water-supplying chamber of condenser script, then on the locular wall of the intake chamber sealed and water-supplying chamber, set up circulating water pipe by the mode of welding and scavenging pump forms the temporary system needed for cleaning, make to set up temporary system in such a way and clean.But installation and the dismounting of this kind of temporary system are complicated, there is the preparation cycle long, the shortcomings such as System recover workload is large, and medicine utilization rate are low, and cleaning needs to use large discharge scavenging pump, the inadequate economical and efficient of cleaning method.
Summary of the invention
It is more convenient that the utility model aims to provide a kind of cleaning operation, the condenser cleaning structure that cleaning agent utilization rate is higher.
Condenser cleaning structure described in the utility model, it arranges distributor in the intake chamber of condenser, in the water-supplying chamber of condenser, arrange liquid trap, and distributor has an import and multiple outlet, and liquid trap then has multiple import one outlet; The import of distributor connects the export pipeline of scavenging pump by pipeline, and each outlet of distributor is then connected to outlet connecting pipe road, be provided with in the end in each outlet connecting pipe road can with the snap joint of Cooling Tubes of Condenser rapid abutting joint; The outlet of liquid trap connects the inlet ductwork of scavenging pump by pipeline, and each import of liquid trap is connected to inlet connecting branch road, be provided with in the end in each inlet connecting branch road can with the snap joint of Cooling Tubes of Condenser rapid abutting joint.
A kind of condenser cleaning structure described in the utility model, during cleaning condenser, in intake chamber, each outlet conduit of distributor is by snap joint, docks fast with one end of part Cooling Tubes of Condenser; Each outlet conduit of liquid trap then connects the other end of Cooling Tubes of Condenser fast by snap joint; Corresponding with the Cooling Tubes of Condenser that liquid trap inlet duct connects by the Cooling Tubes of Condenser that export distributor pipeline is connected, a small-sized scavenger circuit can be formed with scavenging pump.Pass through, snap joint plug for several times connects, and covers all Cooling Tubes of Condenser roads, can complete the cleaning on whole Cooling Tubes of Condenser road easily.Described condenser cleaning structure, the internal volume of its scavenger circuit is very little, and the cleaning agent amount needed for clean cycle is considerably less, and cleaning agent cost is low, and the feature of environmental protection is good.Simultaneously, its cleaning process, distributor is connected by snap joint with Cooling Tubes of Condenser road with liquid trap, installation preparation amount before cleaning is little, simple and quick, and do not need to carry out any transformation to condenser equipment itself, there is not the workload should transformed and bring and the impact on equipment yet.
