Problems solved by technology

[0003] At present, domestic electrolysis companies have no good way to deal with the mud of titanium storage tanks. They usually use relatively clean crude titanium tetrachloride to beat it away, then open the manhole, and manually stand outside wearing a mask and protective clothing. The rake is pulled out, put in a container or sold or washed away with water. These methods have many problems and are very harmful to the human body.

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0027] A cleaning method for a titanium storage tank, comprising:

[0028] ①In a sealed state, use a feeding pump to flush the settled mud in the titanium storage tank to make it suspend;

[0029] ② Then put the suspended mud into the thickener for clarification, which can effectively recover the clarified liquid;

[0030] Repeat steps ① and ② until the titanium storage tank is free of mud.

[0031] A chain-type SVG device suitable for correcting power factor is connected to the three-phase power input end of the titanium storage tank.

[0032] like Figure 1-2 As shown, the chained SVG device includes:

[0033] H-bridge multi-connected multi-level inverter, which is composed of three-phase H-bridge power modules connected to the three-phase power supply, wherein, at least one spare H-bridge unit circuit is added to each phase H-bridge power module ;

Abstract

The invention relates to a working method of a chain type SVG device suitable for correcting the power factor. The chain type SVG device comprises a multi-H-bridge-connected multi-level inverter, an automatic bypass circuit, a sampling circuit, a split-phase current independent control circuit and a pulse width modulation circuit. When a damaged H bridge unit circuit is bypassed, the pulse width modulation circuit is suitable for changing the carrier frequency of carrier wave and triangular wave phase-shifted SPWM of an H bridge power module where the damaged H bridge unit circuit is located so as to obtain pulse modulation waveforms of carrier wave and triangular wave phase-shifted SPWM corresponding to the number of remaining H bridge unit circuits in the H bridge power module.

Description

[0001] This application is a divisional application, the application number of the original application is 2012105407918, the name: a cleaning method for titanium storage tanks, and the application date: 2012-12-13. technical field [0002] The invention relates to a working method of a chained SVG device suitable for correcting power factor. Background technique [0003] At present, domestic electrolysis companies have no good way to deal with the mud of titanium storage tanks. They generally use relatively clean crude titanium tetrachloride to beat it away, then open the manhole, and manually stand outside wearing a mask and protective clothing. There are many problems in these methods, such as putting the rakes out, putting them in containers or selling them or washing them away with water, and they are very harmful to the human body. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a working method of a chain...
