Embodiment Construction

[0038] The technical solutions of the present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0039] Such as Figure 1 to Figure 4 As shown, an on-line rapid pickling device for condensers in a power plant includes a pickling liquid dispensing device 3 and a servo device 4 arranged outside the condenser water chamber 1, and the pickling liquid dispensing device 3 consists of a cleaning agent preparation tank , acid pump and valves, and can be configured with shaped products. An underwater positioning device for precise positioning and a quick filling device for injecting pickling liquid are installed in the condenser water chamber 1. The underwater positioning device depends on the technology. conditions, other lifting equipment with position sensors can also be used, and it is required to be able to operate underwater for a long time with a mechanical device with a repeat positioning accuracy of <2mm. The...

Abstract

The invention discloses an online rapid pickling device and method for a condenser in a power plant. The online rapid pickling device comprises a pickling liquid distribution device and a servo motor which are arranged outside a condenser water chamber, wherein an underwater positioning device for accurately positioning and a rapid filler for injecting pickling liquid are arranged in the condenser water chamber; the servo device is connected with the underwater positioning device; the pickling liquid distribution device is connected with the rapid filler; the servo device is used for transmitting a command to an underwater vertical positioning device in order to drive the rapid filler on a vertical coupler support to arrive at a specified area; a propeller on the support is used for driving the rapid filler to move forwards to be in hermetical butt joint with a condenser tube plate; the liquid distribution device is used for supplying pickling liquid to the rapid filler; the rapid filler is used for filling the pickling liquid into a plurality of rows of condenser heat exchange tubes in a covered area; after set cleaning and soaking time is reached, the rapid filler is separated from the condenser tube plate under the driving action of the propeller, and moves to a next area according to a set program for cleaning continually. By adopting the online rapid pickling device and method, the cleaning time is shortened greatly, the equipment running reliability is enhanced, and the cleaning cost of the condenser is lowered.

Description

technical field [0001] The invention belongs to the field of chemical cleaning of condensers in power plants. It is a new technology for energy saving and emission reduction of heat exchangers. It adopts underwater hydraulic positioning technology to realize rapid online chemical cleaning of scale and stains on heat exchange tubes in condensers. A new technological approach. Background technique [0002] The power plant condenser is one of the main auxiliary equipment widely used in the power system. It is responsible for the cooling task of the exhaust steam of the steam turbine. Its working performance has an important impact on the safe and economical operation of the power plant. During the heat transfer process, scale and stains are easily formed on the inner wall of the water side of the heat exchange tube in the condenser due to the influence of heating and water quality, which will have a negative impact on the performance of the heat exchanger. How to remove scale a...
