Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , the present invention includes a solution tank 1 and a horizontal cleaning tank 2 made of anti-corrosion stainless steel, the solution tank 1 communicates with the horizontal cleaning tank 2 through pipelines, and the inside of the horizontal cleaning tank 2 is installed with a filter element to be cleaned. The detachable splint can install 30-150 contaminated filter elements at a time. By replacing different types of splints, different types of filter elements can be cleaned, and there are pressure gauges PI inlet and outlet respectively at the horizontal cleaning tank 2 inlet and outlet. , PI out, solution tank 1 and horizontal cleaning tank 2 are provided with Y-shaped filter 18, water pump 3, flowmeter 7, first valve 10 and second valve 11 in turn on the pipeline that is connected with horizontal cleaning tank 2, and water pump 3 is ...

Abstract

The invention relates to an off-line filter-cell chemically-cleaning device, which comprises a solution tank, a horizontal cleaning tank, a flow control unit and a temperature control unit. The solution tank is used to mix pharmaceutical agents used for cleaning. The horizontal cleaning tank is used to install filter cells to be cleaned. The flow control unit which comprises a water pump, a bypass and a flow meter can control and adjust flow required for cleaning by adjusting the bypass. The temperature control unit which comprises a heater and a temperature control device is used to adjust the temperature of cleaning fluid. Furthermore, the device system is provided with an agitator, thereby ensuring uniform mixing of cleaning medicines. The system is provided with multiple valves. The device can switch flexibly between two systems of forward-cleaning and backward-cleaning by opening and closing the valves. A detachable-type clamping plate, which is used to fix the filter cells to be cleaned, is installed inside the horizontal cleaning tank. By replacing different types of clamping plates, the device can clean different types of filter cells, such as a wire wound filter cell, a foldable filter cell and a melt-blown filter-cell, etc.

Description

technical field [0001] The invention relates to a device for off-line chemical cleaning of various types of filter elements. Background technique [0002] The filter elements used in condensate polishing are usually wire-wound, folded, and melt-blown, and are widely used in condensate polishing due to their large interception capacity, low running resistance, and strong filtration adsorption. Powdered resin covers the filter and pre-filter. [0003] Regardless of the type of filter element, there will be a significant increase in the initial operating pressure difference during the long-term operation. Using energy spectrum analysis and other experimental methods to analyze the polluted filter element, it is found that the substances blocked in the pores of the fiber lines on the surface of the filter element are mainly iron oxides, and these substances are not simply attached to the surface of the fiber lines, but have occurred A certain precipitation reaction is deposite...
