The bag-type dust collector 3 in this embodiment includes a dust hopper for receiving dust, a box body communicated with the dust hopper, and a pulse device arranged at the upper end of the box body, the box body is divided into a lower box body communicated with the air inlet and the dust hopper, a middle box body communicated with the lower box body, and an upper box body arranged at the top and communicated with the air outlet by two partition plates, the middle box body is suspended with a plurality of filter bags for separating dust, and the filter bags are all communicated with the pulse device. Wherein the lower box body is funnel-shaped, and the small end of opening is communicated with the funnel. The bag-type dust collector 3 in the scheme is mainly used for removing carbon black, particles and dust in waste gas.
Because the female closed machine feed inlet that smelts contains a large amount of dust particulate matters usually, these granule particle diameters are little, and it is inside in the workshop to scatter easily, not only can influence the operation of equipment, also can influence operating personnel's mental health simultaneously. For this purpose, the combined exhaust gas is sent to a bag filter 3 for primary treatment along an inlet duct 2 by a fan. When the dust-containing gas separation device works, dust-containing gas enters from the air inlet, and when the dust-containing gas passes through the dust hopper, part of large-particle dust in the gas is separated out under the action of inertia force and directly falls into the bottom of the dust hopper. The dust-containing gas enters the bag filtering area of the middle box body after passing through the dust hopper, the gas passes through the filter bag, and fine dust is blocked on the surface of the filter bag. The dedusted gas enters the upper box body through the filter bag opening and is then discharged from the air outlet.
Along with the extension of the filtering time, the dust layer on the filter bag is continuously accumulated and thick, the resistance of the bag-type dust collector 3 is continuously increased, and when the resistance of the equipment is increased to a set value, the dust removal is started by the dust removal coordination. The ash cleaning process is to cut off the air duct at the clean air outlet of the chamber to make the cloth bag in the state of no air flow passing through (air stopping and ash cleaning in different chambers). Then, a pulse device is started to perform pulse blowing ash removal by using compressed air, the compressed air rapidly expands in the upper box body in a very short time and then flows into the filter bag, so that the filter bag expands and deforms to generate vibration, and under the action of reverse air flow scouring, dust attached to the outer surface of the filter bag is peeled off and falls into an ash hopper. The closing time of the stop valve is enough to ensure that the dust stripped from the filter bag is settled to the dust hopper after being injected, so that the phenomenon that the dust is attached to the surface of the adjacent filter bag along with the air flow after being separated from the surface of the filter bag is avoided, and the filter bag can thoroughly clean the dust.
The suction filter 4 in this embodiment mainly removes flue gas and oil (chemical oil or sludge) having a large particle size in exhaust gas. The exhaust gas treated by the bag filter is sent to a suction filter 4 for degreasing. When the waste gas containing oil aerosol particles passes through, the waste gas collides with the suction filter chip of the suction filter type oil filter 4, and large oily particles are adhered to the surface of the suction filter chip to realize oil-gas separation, so that the waste gas is purified.
The core of the suction filter 4 is a suction filter chip which is a special filtering and adsorbing material, the shell is made of high-temperature-resistant and corrosion-resistant SUS304(304 stainless steel), the internal filter core chip adopts an alloy wire filter material, and the inside of the filter chip is a special unit with extremely fine gaps and a labyrinth honeycomb design, is of a three-dimensional net structure, has the characteristics of high porosity (more than 95%), good tensile strength and moderate pore size, thereby reducing flow resistance, increasing the storage amount of oil and effectively solving the contradiction between purification and ventilation. When waste gas of oily aerosol particles passes through, the waste gas collides with the purification filter element sheet, large oily particles are adhered to the surface of the filter element sheet, most oily particles are adsorbed on the filter element sheet when the waste gas passes through the filter element, and residual oily molecules of fine particles are rapidly collided for many times due to rapid time change of filtering speed when passing through the inside of the labyrinth and superfine gap chip, and the oily molecules of the fine particles are adhered to the wall of the chip and are settled under the action of gravity in the advancing process of air flow to be purified.
The ion-photocatalytic integrated type device 5 in the present embodiment includes a plasma unit for causing gas to generate electrons and a photocatalytic unit for causing gas to undergo photocatalytic degradation, the plasma unit and the photocatalytic unit being in communication with each other.

The main mechanism of the plasma purification technology is as follows: under the action of an external electric field, electrons get energy and then start to move in an accelerated manner to impact odor gas molecules at a speed of 300 to 3000 ten thousand times per second, when the energy of the electrons is the same as or slightly larger than the energy of a certain chemical bond of the odor gas molecules, inelastic collision occurs, and the electrons convert most kinetic energy into the internal energy of pollutant molecules, so that a series of complex physical and chemical reactions such as ionization, cracking or excitation and the like are initiated to the pollutant molecules, and the chemical bonds of the odor-generating groups are broken, thereby achieving the aim of deodorization.
The plasma method is characterized in that the organic hydrocarbon molecules with peculiar smell are ionized into H + and C4+ plasmas at a certain temperature by a molecular exciter, using high frequency and high voltage and adopting the principle of molecular resonance.
The H +, C4+ plasma enters the catalyst reaction tank and is oxidized into water and carbon dioxide.
4H++O2＝2H2O
C4++O2+CO2
2. A composite photocatalytic section:
the composite photocatalysis device is divided into an efficient pretreatment section and a composite photocatalysis section which are usually integrated, so that the occupied area and the installation workload can be effectively reduced. The high-efficiency pretreatment section is mainly formed by combining modularized professional composite fibers and mainly used for treating each component of waste gas so as to adsorb and remove harmful chemical gas in the waste gas, reduce the pressure of rear-end treatment and improve the waste gas treatment efficiency.
Ultraviolet lamp with specific wavelength is used as light energy donor for photocatalytic oxidation, and the photocatalyst nano particle can be excited to generate electron-hole pair and hole decomposing catalyst under the irradiation of ultraviolet light with certain wavelength. The photocatalytic oxidation of TiO2 is active hydroxyl (OH) and other active oxidation species (O)2-，·OOH，H2O2) The result of the combined action. In TiO2The OH group generated on the surface has high reactivity and reaction energy higher than that of various chemical bond energies in organic matters, and is added with O2 -，·OOH，H2O2The synergistic effect of the active oxidation substances can quickly and effectively decompose the organic substances.
The rough reaction mechanism is:
H2S+O2、O2-、O2+→SO3+H2O
NH3+O2、O2-、O2+→NOx+H2O
VOCs+O2、O2-、O2+→SO3+CO2+H2O
in this embodiment, the air distribution device 6 comprises an odor control box 61, the odor control box 61 is communicated with the ion-photocatalysis integrated device 5 through an air pipe, and a deodorizing membrane is placed in the odor control box 61. The deodorizing membrane is a ZIKE one-way deodorizing dialysis membrane, is a world patent product developed and produced by Vaportek corporation of America, is imported from original United states, meets the requirements of international environment-friendly green products, is accompanied by American safe and harmless certification (M.S.D.S.) except the characteristic that natural components have natural recession, is specially recommended to be used by the Japan society for researching and treating odor countermeasures, and is proved to be safe and harmless by the safety inspection of Guangdong province disease prevention and control center and the Guangdong province microorganism analysis and detection center.
The adopted dry neutralization method mainly takes a Vaportek odor controller as core equipment and a Vaportek deodorization membrane as a main deodorization unit. Odor removing particles are uniformly distributed on the surface of the membrane through VP, and the odor is rapidly removed by utilizing the air convection power, and meanwhile, other external substances cannot be sucked, so that the naturalness of the plant extracting solution is kept forever. The deodorizing particles in the waste gas can quickly and actively capture the odor gas molecules in the air and wrap the odor particles. The common odor molecules are mostly small molecular organic matters (esters, alcohols, aromatic hydrocarbons and the like), and also comprise part of inorganic small molecules such as ozone, ammonia, hydrogen sulfide, hydrocarbons and the like, and the odor molecules have high activity on the surface of olfactory cells and strong irritation, and still have strong olfactory pollution capacity even under the premise that the concentration of each odor component reaches the standard and is discharged, namely the odor molecules have the characteristics of low pollution concentration and high odor intensity. Vaportek particles are natural oily deodorized molecules, and the particles are in non-covalent combination with odor molecules through intermolecular nonpolar interaction, so that the molecules are greatly stabilized, and the activity and the irritation of the molecules are reduced. Further, the increase in specific gravity after the binding is solved by the sedimentation effect. The process is different from chemical reaction process to generate a third substance and masking effect, does not cause secondary pollution, and can thoroughly remove odor.
