Description

A kind of desulfurization wastewater fluorine removal device

Technical field

The utility model relates to desulfurization wastewater processing technology field, in particular to a kind of desulfurization wastewater fluorine removal device.

Background technique

Fluoride waste is such useless from branchs of industry such as phosphate fertilizer, sulfuric acid, electrolytic aluminium, petrochemical industry, electronic components fabrications Water fluorinated volume is high, if can cause seriously to pollute to environment without processing.Water fluorinated volume general control is daily drunk by people 0.4 ~0.6mg/L, long-term drinking fluorinion concentration are unfavorable to human body greater than the water of 1mg/L, serious to cause den tal fluorosis and fluorine bone Disease and some other disease, finally make one disability, can also cause a variety of allergic reactions, genetic disease, cancer, Newborn's defect, or even the generation of meeting induced tumor seriously affect the health and stake holder economy development of people.

During existing plant chimney stalk fluorine removal, defluorination effect is bad, and during long-term fluorine removal, when replacement fluorine removal dress It sets or when defluorinating agent, needs to suspend desulfurization wastewater fluorine removal process, influence working efficiency.

Summary of the invention

To solve the above-mentioned problems, the utility model provides a kind of desulfurization wastewater fluorine removal device, the technical solution of use It is as follows:

A kind of desulfurization wastewater fluorine removal device, which is characterized in that be mainly connected including sedimentation basin, at least two with sedimentation basin Filtering ponds, the sedimentation basin top are equipped with blender, and sedimentation basin water outlet is connected with primary flow pipe, and filtering ponds water inlet goes out with master It is connected separately with water inlet pipe between water pipe, the switch valve of control pipeline on-off, the mistake are respectively equipped on the water inlet pipe Defluorination of Formation Mater By Adsorption On Activated Alumina layer and the heating device for heating of Activated aluminium oxide fluorine removal layer are equipped in filter tank.

Preferably, the active oxidation aluminium layer and be located at work that the Defluorination of Formation Mater By Adsorption On Activated Alumina layer is made of activated alumina particle Property alumina layer influent side and water outlet side filter screen form.

Preferably, the heating device is the Electrothermic tube with fins being fixedly connected on the outside of filter screen.

Preferably, the filtering ponds are highly gradually decreased from water inlet to water outlet direction.

The utility model has the beneficial effects that:

1, activated alumina is reusable after heating, drying, not only goes fluorine effect good but also at low cost；

2, multiple filtering ponds setting in parallel with sedimentation basin is avoided because single filtering ponds break down or need replacing It causes to shut down when fluorine device, improves working efficiency；

3, containing for fluorine in wastewater can be effectively reduced after the multistage drop fluorine of sedimentation basin and filtering ponds in desulfurization fluoride waste Amount, achievees the purpose that cycling and reutilization.

Detailed description of the invention

Fig. 1 is desulfurization wastewater fluorine removal device structural schematic diagram

Wherein, 1- sedimentation basin, 2- agitating device, 3- primary flow pipe, the first water inlet pipe of 4-, the second water inlet pipe of 5-, 6- Switch valve, the first filtering ponds of 7-, 8 second filtering ponds, 9- active oxidation aluminium layer, 10- filter screen, 11- fin heats pipe.

Specific embodiment

With reference to the accompanying drawing 1 and specific embodiment the utility model is described in further detail.

As shown in Figure 1, it includes sedimentation basin 1, first filtering ponds in parallel with sedimentation basin 1 that desulfurization wastewater, which removes fluorine device mainly, 7 and second filtering ponds 8, the top of sedimentation basin 1 be equipped with for stirring the agitating device 2 sedimentation basin 1 inside, the first filtering ponds 7 lead to It crosses the first water inlet pipe 4 to be connected with the primary flow pipe 3 of sedimentation basin 1, the second filtering ponds 8 pass through the second water inlet pipe 5 and sedimentation basin 1 Primary flow pipe 3 be connected, and control pipeline on-off is respectively provided on the first water inlet pipe 7 and the second water inlet pipe 8 The water outlet of switch valve 6, the first filtering ponds 7 and the second filtering ponds 8 is equipped with the outlet valve for controlling on-off, the first filtering Middle part is equipped with Defluorination of Formation Mater By Adsorption On Activated Alumina layer in pond 7 and the second filtering ponds 8, and the Defluorination of Formation Mater By Adsorption On Activated Alumina layer includes by active oxygen Change the active oxidation aluminium layer 9 of alumina particles composition and the filter screen 10 positioned at 9 two sides of active oxidation aluminium layer, filter screen 10 has aperture The steel wire of 2mm is made, and flows on direction in waste water, and filter screen 10 is located at the front and rear sides of active oxidation aluminium layer 9, this Outside, several fin heats pipes 11 are fixedly connected on the outside of two layers of filter screen 10.

Specifically, 1 size of sedimentation basin are as follows: 2030cm*2030cm*1530cm the first filtering ponds 7 and the second filtering ponds 8 Size are as follows: 1690cm*1510cm*1250cm, and the first filtering ponds 7 and the second filtering ponds 8 are from water inlet to water outlet It is distributed from high to low on direction.

After the waste water that desulfurization generates enters sedimentation basin, agstone is added in sedimentation basin, it is heavy to stir by agitating device 2 Bottom, the waste water after precipitating enter the first filtering ponds 7, are adsorbed by active oxidation aluminium layer 9, will be in water at fluorine absorption Reason, the water being disposed is flowed out by the water outlet of the first filtering ponds 7, after running a period of time, filtered water fluorinated volume When rising, close the first water inlet pipe 4 on switch valve 6, open the second water inlet pipe 5 on switch valve switch over into The lasting processing of row waste water opens the fin heats pipe 11 inside the first filtering ponds 7, to active oxidation aluminium layer 9 at the same time It is dried, since not only absorption property is good for activated alumina, and there is good thermal stability, it can after heating, drying Recycling, while the design separately filtered using multiple filtering ponds allow the processing of desulfurization wastewater to keep continuing progress, It reduces because of more changing device or removes fluorine material due to the device time out of service.

By precipitating+Defluorination of Formation Mater By Adsorption On Activated Alumina, desulfurization fluoride waste is improved well, can put down desulfurization fluoride waste It is fluorine-containing from 25mg/L or so, be down to 5mg/L hereinafter, desulfurization wastewater can qualified discharge better than national standard.

The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvement can also be made, these improvement also should be regarded as The protection scope of the utility model.
