The blowdown filter for the desalted water station is suitable for the blowdown filtering of the desalted water station.
Description
Technical field
The present invention relates to a kind of desalted water station drain filter, belong to desalted water station blowdown filtration art.
Background technology
At present, the filter that desalted water station uses because the blow-off pipe disposal ability of its use is limited, after to its backwash, can cause when just washing blowdown not smooth, makes impurity not discharge at short notice, influences the effluent quality of filter.
Summary of the invention
The present invention is for the not smooth problem of blowdown of the filter that solves the desalted water station use, and a kind of desalted water station drain filter is provided.
Desalted water station drain filter according to the invention; It comprises header tank, water inlet pipe; It also comprises a plurality of pipes of turning one's coat, blowdown tank, siphon down-comer, auxiliary siphon tube, exhaust tube, siphon tedge, siphon destructing tube, siphon destructive bucket, blow-off pipe, goes out bucket and outlet pipe
The stage casing of header tank is provided with sand filter blanket, and the bottom of this sand filter blanket is the clear water layer, and the top of this sand filter blanket is reservoir bed; Water inlet pipe is communicated with the sand filter blanket of header tank, the clear water layer of an end connected set water tank of a plurality of pipes of turning one's coat, the reservoir bed of the other end connected set water tank of a plurality of pipes of turning one's coat; Outlet pipe passes the sidewall at header tank reservoir bed place and is fixed on this sidewall; The water inlet of outlet pipe is communicated with bucket, and the water inlet that goes out bucket is lower than the peak level of reservoir bed
The bottom of header tank is communicated with blow-off pipe, and blow-off pipe is provided with control valve;
The model of blow-off pipe is DN150;
Water inlet pipe is communicated with through the head end of siphon tedge with the siphon down-comer; The end of siphon down-comer is positioned at blowdown tank, and the end of this siphon down-comer is provided with water seal, the head end of the head end connection siphon destructing tube of siphon down-comer; The end of siphon destructing tube is positioned at the siphon destructive bucket; The head end of auxiliary siphon tube is communicated with the siphon tedge, and the end of auxiliary siphon tube is positioned at blowdown tank
One end of exhaust tube is communicated with auxiliary siphon tube, and the other end of exhaust tube is communicated with the siphon down-comer.
Also be provided with dividing plate in the said blowdown tank, said siphon down-comer and auxiliary siphon tube are positioned at the homonymy of blowdown tank internal partition.
Advantage of the present invention is: the present invention has improved the pollution discharge capability of filter through transforming the blow-off pipe of drain filter, has alleviated the burden of upstream device.The present invention is transformed into the DN150 blow-off pipe with the DN50 blow-off pipe that uses in the existing equipment, makes the blowdown disposal ability of filter reach 90T/h.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The specific embodiment one: this embodiment is described below in conjunction with Fig. 1; The said desalted water station drain filter of this embodiment; It comprises header tank 1, water inlet pipe 2; It also comprises a plurality of pipes 3 of turning one's coat, blowdown tank 4, siphon down-comer 5, auxiliary siphon tube 6, exhaust tube 7, siphon tedge 8, siphon destructing tube 9, siphon destructive bucket 10, blow-off pipe 11, goes out bucket 12 and outlet pipe 13
