Abstract
The invention relates to a soot treatment device of casting, metallurgy and other relevant industries. The device is a cupola dust and waste gas treatment device which needs two times of treatment, namely, firstly using atomized water and then using aqueous alkali for treatment, and can be suitable for small and medium-sized enterprises. The device mainly comprises a cupola, a chimney, a fan, a shower bath, an air compressor, a reaction tank, an air pipeline, etc. The air pipeline sequentially and circularly connects the cupola, the chimney, the fan, the shower bath, the air compressor, the reaction tank and the cupola. The shower bath is filled with water with certain depth, proper concentration of saponified oil is added, and the top part of the shower bath is provided with a device that atomizes water flow downward at high speed. The reaction tank is filled with aqueous alkali, after compressed by the air compressor, the waste gas with dust removed is sent to the bottom part of the reaction tank, and the air outlet end of the reaction tank is positioned at the upper part of the reaction tank. The dust and waste gas generated in the combustion of the cupola are sequentially treated by the shower bath and the reaction tank for two times, and the soot can be treated completely.
Description
Technical field
The present invention relates to cast, the soot processing device of relevant industries such as metallurgy, particularly a kind of twice processing promptly utilizes atomized water to utilize aqueous slkali to absorb the cupola dust and waste gas treatment device of dust and harmful substance more earlier.
Background technology
In relevant industries such as casting, metallurgy, inevitable a large amount of dust and the waste gas of ground warp smoke stack emission wherein contains a large amount of as pernicious gases such as carbon monoxide, nitric oxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, sulfur trioxide, hydrogen sulfide.Known, the enterprise that has adopts high chimney emission dust and waste gas, but can only alleviate oneself contaminated degree among a small circle, and the enterprise that has has also taked soot processing device, but cost is too high, effect is also undesirable.In fact more use the medium-sized and small enterprises of furnace cupola that chimney stack can not be arranged, flue dust has not directly discharged through just handling, and becomes local serious environmental pollution sources, has greatly influenced people's quality of life and health.Therefore press for a kind of practicality of invention, efficient, less investment, use cost is low, treatment effect is good soot processing device, particularly a kind of dust and waste gas treatment device that can be adapted to the medium-sized and small enterprises furnace cupola.
Summary of the invention
In order to solve relevant medium-sized and small enterprises dust treatment problem, cupola dust and waste gas treatment device of the present invention provides a kind of practicality, cost is low, treatment effect is good soot processing device.
The technical solution adopted in the present invention is:
Cupola dust and waste gas treatment device, mainly be made of furnace cupola, chimney, blower fan, fountain, air compressor machine, reaction tank, air pipe etc., described air pipe connects furnace cupola, chimney, blower fan, fountain, air compressor machine, reaction tank, furnace cupola circulation successively.Described blower fan sucks the dust waste gas that furnace cupola produces, and is displaced into described fountain then; The water of certain depth is housed in the described fountain and adds the saponified oil of suitable concn, so not only help taking away dust, and help antirust.The top of described fountain has makes current descend the device of atomization at a high speed, and the described water that has added saponified oil can be pumped to the top arrangement of fountain, and described top arrangement has the function that makes current descend atomization at a high speed, so dust is dashed by high-velocity flow.The waste gas of removing dust is sent into the bottom of described reaction tank after by described air compressor machine compression, the aqueous slkali of certain depth, debita spissitudo is housed, as NaOH or aqua calcis in the described reaction tank; The outlet side of described reaction tank is positioned at the top of described reaction tank.Absorbed by aqueous slkali behind the alkali reaction in carbon dioxide in the waste gas, nitrogen dioxide, sulfur dioxide, sulfur trioxide, hydrogen sulfide etc. and the described reaction tank, contain and get back in the furnace cupola after carbon monoxide, nitric oxide production residual gas are overflowed from aqueous slkali.

The invention has the beneficial effects as follows: the dust waste gas that produces during the furnace cupola burning successively passes through twice processing of described fountain and described reaction tank, and described again cupola dust and waste gas treatment device is the piping installation of circulation, and is more thorough to dust treatment.Have practicality, less investment, use cost is low, efficient, treatment effect is good characteristics.
Description of drawings
Further specify below in conjunction with figure of the present invention:
Fig. 1 is the structural representation of described cupola dust and waste gas treatment device,
Among the figure, 1. furnace cupola, 2. chimney, 3. air pipe I, 4. blower fan, 5. air pipe II, 6. fountain, 7. air pipe III, 8. air compressor machine, 9. air pipe IV, 10. reaction tank, 11. air pipe V.
The specific embodiment
In Fig. 1, air pipe I (3) is connected the top of chimney (2) with blower fan (4), and air pipe II (5) connects the inlet end of blower fan (4) and fountain (6).The top of fountain (6) has makes current descend the device of atomization at a high speed, adorns a water pump in the bottom of fountain (6), and water pump is connected to described top arrangement; Fountain (6) is equipped with the water of certain depth and adds the saponified oil of suitable concn; The available transparent material manufacturing of fountain (6) is so that observe; Outlet pipe is arranged at the bottom of fountain (6).Air pipe III (7) is connected the outlet side of fountain (6) with the inlet end of air compressor machine (8), the end of air pipe IV (9) is connected with the outlet side of air compressor machine (8), and the other end is connected to the bottom of reaction tank (10).Top at reaction tank (10) has the charge door that can screw, and reaction tank (10) has the device and the transparent windows that can show acid-base value, and outlet pipe is arranged at the bottom of reaction tank (10).The outlet side that air pipe V (11) will be positioned at reaction tank (10) top is connected with furnace cupola (1) again.Escaping gas has enough pressure through air compressor machine (8) compression back enters the bottom of solution in the reaction tank (10) by air pipe IV (9) after, can get back to the furnace cupola (1) from air pipe V (11) easily to burn once more.
