Filter element washing device

Abstract

The invention belongs to the technical field of industrial chemical washing devices and in particular relates to a filter element washing device. The device comprises a washing tank, wherein the washing tank comprises a tank body and a tank cover; the tank body is internally provided with a fixed plate and a bottom plate; a first channel on a side wall of the tank body is communicated with a firstend of a first three-way pipe and a frontward washing water inlet valve is arranged at the first end; a backwashing water inlet valve is arranged at a second end of the first three-way pipe; a firstcheck valve is connected with a third end of the first three-way pipe; the first check valve is connected with a water outlet of a first washing pump; the first washing pump is communicated with the water outlet of a water tank; a second channel is communicated with the first end of a second three-way pipe; the second end of the second three-way pipe is communicated with the backwashing water inlet valve; a third channel is communicated with the first end of a third three-way pipe and a backwashing water outlet valve is arranged at the first end of the third three-way pipe; a frontward washingwater outlet valve is arranged at the second end of the third three-way pipe; and a third end of the third three-way pipe is communicated with the water inlet of the water tank.

Description

technical field [0001] The invention belongs to the field of industrial chemical cleaning devices, in particular to a filter element cleaning device. Background technique [0002] Water resources are scarce in northern my country. Many thermal power plants use air-cooled units, and the condensate polishing system of air-cooled power plants uses powder filters. Powder-covered filters have the advantages of high applicable temperature, simple equipment, and convenient operation. [0003] However, after a period of operation, there are often problems such as high operating pressure difference, too fast rise in operating pressure difference, and significantly shortened operating cycle, which seriously affects the economy of the powder resin filter operation. The main reason is that the filter element in the filter is polluted by the corrosion products of iron, and the filter element is blocked by fouling. Chemical cleaning of polluted filter elements is an effective solution, b...

Problems solved by technology

[0003] However, after a period of operation, there are often problems such as high operating pressure difference, too fast rise in operating pressure difference, and significantly shortened operating cycle, which seriously affects the economy of the powder resin filter operation.

The main reason is that the filter element in the filter is polluted by iron corrosion products, and the filter element is blocked by dirt.

Chemical cleaning of polluted filter elements is an effective solution, but due to the large number of filter elements, a single cleaning project requires a large amount of work, a long construction period, and low cleaning efficiency
