A filter tank pressure stabilization energy dissipation and material leakage diagnosis system and method

Abstract

The invention provides a steady-pressure energy dissipation and leakage diagnosis system and a method thereof for a filter. The system comprises a steady-pressure energy dissipation device and a gas stripping device, wherein the steady-pressure energy dissipation device comprises energy dissipation valves, energy dissipation tubes and energy dissipation inlet components; the energy dissipation valves are positioned above the filter; the energy dissipation tubes are positioned on the lower side of a filtering plate after the lower ends of the energy dissipation tubes penetrate through the filtering plate inside the filter; the energy dissipation tubes are in threaded connection with the energy dissipation inlet components; outer sides of the energy dissipation tubes are seamlessly joined with the filtering plate; the gas stripping device comprises a gas stripping pipeline and a gas stripping valve; an outlet vertical tube of the gas stripping pipeline is arranged opposite to the energydissipation inlet components of the steady-pressure energy dissipation device at certain intervals. Therefore, problems such as filtering plate propping in gas-water backwash operation are avoided, inaddition, water on the lower side of the filtering plate can be collected to judge the quality when the filter is operated normally, and whether material leakage is caused or not can be judged.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a pressure-stabilizing energy dissipation and material leakage diagnosis system and method for a filter tank. Background technique [0002] Existing filter tanks with filter heads and assembled filter plate technology, after a certain number of years of operation, the filter head will become fouled or contaminated by algae growth. In this case, air-water backwashing (including separate air washing and combined air-water reverse During the operation, the air (water) washing channel is blocked, and the backwash air (water) cannot be released through the filter head. An air (water) layer is formed in the lower part of the filter plate, which easily causes the filter plate to fall off and the top plate collapses. The filter tank is running; and, because the filter tank adopts the filter beam to support the filter plate, the filter beams are mutually blocked, causing the air (water) to be u...

Problems solved by technology

[0005] In order to solve the above-mentioned problems, the object of the present invention is to provide a kind of pressure stabilization and energy dissipation of the filter tank and material leakage diagnosis system and method thereof, through the present invention, not only can prevent stronger gas (water ) pressure cannot be released through the filter head and filter layer, resulting in problems such as the top plate of the filter plate or the pressure block of the filter plate falling off, and can quickly collect the water quality of the lower layer of the filter plate without affecting the operation of the filter tank, and judge whether the lower part of the filter plate is There is leakage of filter material
