A sewage discharging and a gas discharging devices and a sparger flushing device are reserved, and filter sticks which are used as filter elements are used in a water treating device; every filter stick is vertically arranged on every unit connecting tube of which the output end is provided with a pulse valve of which the number of water inlets is consistent with the number of unit connecting tubes. The suspending purifier has the advantages of simple structure, stable performance, convenient operation, easy cleanness, continuous running and high work efficiency and can be suitable for being used for treatment for various suspended substances.

Description

The suspension clarifier

The utility model relates to sewage disposal, particularly to a kind of purifying processing device of smoke abatement and dust control water.

Present filtration method hydrotreater to smoke abatement and dust control water and other suspension sewage disposal use, mainly by the hydrotreater main body, blowdown, exhaust apparatus and spray thrower flusher etc. partly constitute, and adopt PE or PA pipe as filter element in the hydrotreater main body.The deficiencies in the prior art part is: blocked easily around 1, the filter element complex structure, device, element itself is not easy to be cleaned; 2, be subjected to its structural limitations, flushing or blowback can only be regularly, shutdown, emptying are carried out, and increased the workload of operation, and reduced the efficient of equipment.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of simple in structure, and easily cleaning is easy to operate, and makes and move suspension purifier continuously.

Can take following technical scheme to realize purpose, keep blowdown, exhaust apparatus and spray thrower flusher, and in the hydrotreater main body, adopt filter stick as filter element, each filter stick all is vertically mounted on the unit connecting leg, and the output of unit connecting leg is installed into mouth of a river number and the consistent pulse valve of unit connecting leg number outside the hydrotreater main body.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 5 is the vertical view of Fig. 4.

The hydrotreater main body of suspension clarifier is an airtight tank body, and it is suitable to adopt metal material to be fabricated to, and parts such as blowdown, exhaust apparatus and spray thrower flusher can adopt the existing various device that adapts to constitute.Filter stick (1) one filter element in the accompanying drawing institute example is by the granular filler (5) of managing (4), centre in the rigid support and be coated on outer field filtering layer (6) formation: interior Guan Yiduan sealing, the other end is screw thread or flange arrangement, for being connected, have permeable hole (7) on the tube wall of interior pipe with unit connecting leg (2).Interior pipe should adopt corrosion resistant rigidity tubing to constitute, and its active section has many permeable holes, and the size in hole and what can be selected as required.Filler can adopt the anti-corrosion rigid body of stone, plastic grain and so on to constitute.The filtering layer of outermost is the surface filtration layer, and it can adopt materials such as various nets, cloth to constitute, and its density and material also can be taken the circumstances into consideration selected as required.This bar-shaped filter element can obtain very large specific filtration resistance surface area, intensity is big, makes easily, and cost is low, convenient maintenance and replacement, mobility strong, also cleaning easily.Filter stick also can adopt similarly other structural shape, and its length, thickness, hierarchical relationship, material etc. all can be selected combination on demand.Filter stick filter element vertical is installed on the unit connecting leg (2), and promptly some filter sticks are a unit, and they all are installed on the same connecting leg, forms some unit in the hydrotreater main body.The quantity of filter stick element should be selected according to the water quality and quantity needs in the quantity of unit, arrangement mode and the unit.Pulse valve in the accompanying drawing institute example is constituted by the flap (9) that seals cavity volume valve body (8) and be rotating with it, flap is the fan-shaped component of central angle≤360 °/n, number n is consistent with unit connecting leg number in advancing on the valve body (going out) mouth of a river (10), and valve body is provided with axially (advancing) mouth of a river (11).Pulse valve can adopt metal or engineering plastics manufacturing, n=4 among the figure, valve body maintains static, flap can drive its rotation by deceleration device, in its when rotation, can only block wherein some or severally go out (advancing) mouth of a river, because flap rotatablely moves continuously, respectively go out blocked again and again successively,---open-minded, the open-minded---obstruction in (advancing) mouth of a river, make water-in and water-out form periodic stream of pulses.Form periodic stream of pulses as long as can realize above-mentioned functions, pulse valve also can adopt other structure, reaches effect same.Going out on the valve body (advancing) mouth of a river should evenly distribute by circumference, and effect is good.Sewage pump injects former water in the hydrotreater main body, and former water enters filter stick inside by the filtration of filter stick filter element surface, compiles in the people unit connecting leg, and the filtered water in each unit flows out the hydrotreater main body, enters pulse valve (II); When flap passed through each water inlet successively, the blocked mouth of a river made then that filter stick is inside and outside to present pressure balance, because filter element is vertically installed, angle of repose is 0 °, made the suspension of its surface attachment and very easily came off.

Generally, though suspension reaches the resistance limit easily, be easier to flushing, when lacking adherence, pulse valve (II) is only established in hydrotreater main body outside, and inside sets spray thrower and cleans and can meet the demands.When suspension was the graininess filter cake, it had permeability preferably, because the gravity effect, filter cake promptly comes off before the resistance that do not reach capacity voluntarily, so, also pulse valve can be set, and only regularly spray Cleaning for High Capacity gets final product.

If the difficult flushing of filter cake when the colloidality suspension is arranged, also should be provided with back purge system.Back purge system in the accompanying drawing institute example is connected and composed with pipeline by accumulator (12), pulse valve (I), and the axial water inlet (11) of pulse valve (1) is communicated with accumulator, and the delivery port of pulse valve (10) is connected with the unit connecting leg.The amount of capacity of accumulator can determine as required, is higher than water pump water filling in jar of sewage pump by-pressure head, and pulse valve I, II drive synchronous operation by same deceleration device, but both " open " with " obstruction is " corresponding.When a certain unit during by pulse valve II " obstruction ", pulse valve I but is in " open-minded " position simultaneously, and the water under high pressure that is provided by accumulator enters the unit, and the soil suspension on back flush filter stick surface reaches more effective flushing from inside to outside.Long operational time, but emptying equipment, with spray thrower flushing device inside.Sediment is discharged by the down blow valve, and floating thing is discharged by scum valve.Open when beginning operation, the air in the water place device main body is discharged by air bleeding valve.

The relative prior art of the technical program has following advantage:

1, each parts and overall structure are all comparatively simple, and stable performance is easy and simple to handle, Easily cleaning;

2, continuously operation, high efficiency is applicable to the processing of various suspensions.
