Abstract
The invention provides a high-speed filter backwashing material spilling-prevention device. In use, because of unstable pressure values of backwashing water and compressed air, a high-speed filter easily causes a filter material loss and spilling and the filter material loss influences filtering effects and product quality. The high-speed filter backwashing material spilling-prevention device is characterized in that the device comprises a burden distribution baffle plate in the main body of a high-speed filter, the burden distribution baffle plate has an umbrella-shaped structure and a direction of the burden distribution baffle plate inclining downward and a horizontal plane form an included angle of 15-30 DEG C. The device can effectively prevent filter material loss of a high-speed filter in backwashing.
Description
Technical field:
The present invention relates to anti-race of a kind of high rate filter backwash and expect device, belong to energy environment protection technical field.
Background technology:
In the production process of steel industry, high rate filter is the necessary equipment that water system improves system water quality, it is adaptable to the turbid circulating water of purified treatment hot rolling, steel-making, continuous casting in iron and steel enterprise, and the other filter in circulation water of blast furnace system processes.High rate filter, in use due to backwashing water and compressed-air actuated pressure transient, very easily causes filterins media run-off, occurring to run material situation, affecting filter effect, thus having influence on product quality after filterins media run-off.We are by being analyzed the backwash process of high rate filter, study high rate filter backwash control method, filtrate is effectively intercepted, it is prevented that high rate filter backwash occurs to run material situation.
The patent documentation that retrieval is relevant does not find application record in the present system, retrieve similar content mainly to have: Application Number (patent): CN200710158986.5 " backwashing material-losing prevention control method of water treatment sandstone filter ", describe a kind of backwashing material-losing prevention control method of water treatment sandstone filter, pressure transducer is installed after backwash compressed air piping regulates valve, negate wash compressed air pressure signal give PLC, PLC by backwash compressed air pressure signal control air line regulate valve aperture；Pressure transducer is installed after backwash water pipeline regulates valve, negate wash water pressure signal and give PLC, PLC controls backwash water pipeline by backwash water pressure signal and regulates the aperture of valve, in filter interior, water-level probe is installed simultaneously, negate wash water water level signal and give the aperture that PLC, PLC control backwash water pipeline adjustment valve according to backwash water water level signal.This invention ensures that filter constant level, efficiently controlled the dynamic process of backwash, backwash intensity can be reached, do not run again material, thus thoroughly improving filtering tank backwash process.
Backwash water and compressed-air actuated valve are carried out aperture control mainly through PLC by this invention, backwash water, atmospheric pressure can be control effectively, its drawback mainly installs water-level probe in filter, owing to float and oil content are higher in turbid circulating water system, water-level probe very easily breaks down, water level in filter is caused to be difficult to control to, thus occurring to run material situation.
Application Number (patent): CN201120274223.9 " a kind of backwashing run-prevention filter material system for filter material filter " describes a kind of backwashing run-prevention filter material system for filter material filter, it is mainly made up of flow control valve, filtering material filter, buffering isolating device, liquid level Servocontrol device, electrical apparatus control system, can arbitrarily add big reverse washing intensity when there is filtering material filter backwash, can automatically control, thoroughly clean the advantages such as filtrate, the also not loss of qualified filtrate.It is characterized in that being entered before backwash pipeline by flow control valve regulable control, flow control valve and electrical apparatus control system servo action by backwash water pump, dynamically regulate the size of backwash intensity.
Backwash water flow is mainly controlled by this invention by flow control valve and liquid level servomechanism installation, dynamically regulates the size of backwash water intensity, and when mixing wastewater with air backwash, liquid level servomechanism installation is difficult to accurately carry out Level Detection, it may occur that run material situation.
Summary of the invention:
It is an object of the invention to provide anti-race of a kind of high rate filter backwash to expect device for above-mentioned Problems existing, effectively prevent high rate filter from filterins media run-off occurring when backwash.
Above-mentioned purpose is realized by following technical scheme:
High rate filter backwash is anti-runs material device, and including the distributing baffle being arranged on high rate filter body interior, described distributing baffle is umbrella-shaped structure, and the angle between the downward-sloping direction of described distributing baffle and horizontal plane is 15-30 °.
Described high rate filter backwash is anti-runs material device, and described distributing baffle is arranged on described high rate filter by central shaft support, and this is internal, and the central axis of the drift angle of described distributing baffle and described high rate filter charging aperture is on same straight line.
Described high rate filter backwash is anti-runs material device, described distributing baffle is provided with two-layer, at the 1/3-1/2 of the height that the distributing baffle of bottom and the distance between the distributing baffle at top are described high rate filter, it is positioned at the diameter of distributing baffle of bottom more than the diameter of superposed distributing baffle.
Described high rate filter backwash is anti-runs material device, is connected by connecting rod between described distributing baffle and described central shaft support.
Beneficial effect:
The distributing baffle that the present invention is arranged, when former water is entered high rate filter inside by water inlet pipe, carry out water distribution uniformity by distributing baffle, it is prevented that flow of inlet water fluctuation causes the internal filtrate of high rate filter random layer occur, during high rate filter normal filtration, distributing baffle plays the effect of stable water inlet current；When filtrate changed by high rate filter; quartz sand, anthracite are entered by high rate filter top manhole; owing to high rate filter height is higher; filter interior filter cap can be impacted when loading by filtrate; filter cap is caused to damage; after the present invention is provided with distributing baffle, filtrate is cushioned by distributing baffle, and filter interior filter cap is played certain protective effect；Backwashing water is by, after entering filter interior, being intercepted by the runner of filter interior distributing baffle, return in high rate filter, it is prevented that filterins media run-off occurs during Filter Back Washing.
