Abstract

The invention discloses a sedimentation device which is characterized by comprising a water inlet pipe, an outer partition groove, a gravity sedimentation groove, a water outlet pipe and a conical groove; the water inlet pipe is installed in the gravity sedimentation groove; the bottom part of the outer partition groove and the outer part of the gravity sedimentation groove are connected; the water outlet pipe is connected with the outer partition groove; the conical groove is connected with the gravity sedimentation groove; the edge of the gravity sedimentation groove is lower than the edge of the outer partition groove; and a solid-liquid mixture outlet pipe below the conical groove is connected with a solid-liquid separation device. The sedimentation device can recover valued or harmful solid phase media in a solid-liquid mixture in flue gas spraying and sewage purification in each industry, and is beneficial to relieving labor intensity, improving the economic benefit, improving the device utilization ratio, and reducing the construction area of the device during the recovery process.

Description

A kind of sedimentation device

Technical field

The present invention relates to a kind of chemical metallurgy sedimentation device.

Background technology

When carrying out as required flue gas spray, sewage purification, usually adopt settling tank to process, the high low head of breach by a plurality of ponds, solidliquid mixture flow to last pond from first pond, with action of gravitation solid phase is stayed in the pond by flowing, liquid-circulating uses or carries out next process and process, accumulate when too much must cleaning for the solid phase precipitum in pond after a while, generally take the labor cleaning, in scale removal process, increase labour intensity, polluted environment, the utilization rate that has reduced equipment increases the construction area of equipment.

Summary of the invention

The object of the present invention is to provide a kind of sedimentation device, overcome former settling tank and process the shortcoming that floor space is large, need the bothersome effort of labor cleaning.

A kind of sedimentation device, it is characterized in that: comprise water inlet pipe, outer separate slot, gravitation settler, outlet pipe, cone tank, water inlet pipe is contained in the gravitation settler, outer separate slot bottom links to each other with gravitation settler is outside, outlet pipe connects outer separate slot, cone tank connects gravitation settler, and the gravitation settler edge is lower than outer separate slot edge, and the beneath solidliquid mixture of cone tank goes out pipe and is connected with solid-liquid separating equipment.

Further, water inlet pipe is to be contained in the gravitation settler center, and according to the effect of settling requirement to described sedimentation device, gravitation settler can be established one or more.

The present invention can make the recovery that valency or harmful solid-phase media are arranged in the solidliquid mixture in the flue gas spray, sewage purification of industry-by-industry, be conducive in removal process, reduce labor intensity, increase economic efficiency, improve the utilization rate of equipment, reduce the construction area of equipment.

The specific embodiment

Describe embodiments of the present invention in detail below in conjunction with accompanying drawing:

The present embodiment adopts two gravitation settlers.Ammonium tetramolybdate production process: take molybdenum concntrate as raw material, so must roasting be separated by the molybdenum in the molybdenum bisuphide and sulphur, make the molybdenum bisuphide that is insoluble to ammoniacal liquor be converted into the molybdenum trioxide that is soluble in ammoniacal liquor through after the roasting.In roasting, must heating make its burning, affect that the fine or not factor of molybdenum oxide has the height of temperature, the size of oxygen supply in the roasting.The general methods such as air compressing air-blowing and air-introduced machine that adopt when oxygen supply use air-introduced machine must take away dust in some roasting process and the molybdenum trioxide of distillation.In the common employing of the molybdenum trioxide that reclaims dust and distillation is cooling sprayer, the molybdenum trioxide of dust and distillation is reclaimed in the spray sedimentation, allow and flow into settling tank with dust and molybdenum trioxide solidliquid mixture, solidliquid mixture flow to last pond from first pond, with action of gravitation solid phase is stayed in the pond by flowing, liquid-circulating uses or carries out next process and process, accumulate when too much must cleaning for the solid phase precipitum in pond after a while, generally take the labor cleaning, in using artificial scale removal process, increased labour intensity, pollute environment, reduced the utilization rate of equipment.

Now adopt sedimentation device of the present invention, comprise water inlet pipe 1, outer separate slot 2, gravitation settler 1, outlet pipe 4, cone tank 5, gravitation settler 2 11, water inlet pipe 1 is contained in gravitation settler 2 11 centers, outer separate slot 2 bottoms and 3 outside linking to each other of gravitation settler, outlet pipe 4 connects outer separate slot 2, gravitation settler 3 edges are lower than outer separate slot 2 edges, outlet pipe 4 links to each other with spray column 8 by liquid pump 9, gravitation settler 1 in cone tank 5 connects, gravitation settler 1 links to each other by tube connector 12 with gravitation settler 2 11, solidliquid mixture goes out pipe 6 and is connected with solid-liquid separating equipment under two cone tanks, water inlet pipe 1, outlet pipe 4 and solidliquid mixture go out pipe 6 energy bearing certain pressure and valve are housed, and in the spray column 8 spray equipment are arranged.Concrete operation method: first toward gravitation settler 2 11, gravitation settler 1 and outer separate slot 2 are filled with water, air-introduced machine is opened sending into spray column 8 with the flue gas of dust from flue dust inlet connecting branch mouth 7, open outlet pipe 4, valve on the water inlet pipe 1, start liquid pump 9 on the outlet pipe 4, make water in spray column 8 interior circulations, dust in the flue gas is brought into interior gravitation settler 2 11, gravitation settler 2 11 is higher than gravitation settler 1, under action of gravitation, flow to gravitation settler 1 by tube connector 12, recycling gravitation settler one 3 edges are lower than outer separate slot 2 edge overflows to outer separate slot 2, continue circulation by outer separate slot 2 upper water-out pipes 4, gravitation settler 2 11 plays buffering and increases the effect of sedimentation, the solid phase of gravitation settler 1 and gravitation settler 2 11 is after accumulation a period of time, opens 5 times solidliquid mixtures of cone tank and goes out valve on the pipe 6 and carry out press filtration and finish the solid phase work in the solidliquid mixture of reclaiming.

Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention; make without departing from the inventive concept of the premise some alternative or obvious modification that are equal to; and performance or purposes are identical, then should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
