In order to further remove the pollutants, a common method is to add special equipment for purification, such as electric dust removal equipment, lime magnesium oxide desulfurization equipment and the like, and the equipment has high manufacturing cost and running cost, so that the cost for treating the atmospheric pollution is increased, and the popularization and application of the equipment are also limited.
Third, the invention

The utility model provides an atmosphere pollution clarification plant, its design has stronger scientificity: first, according to raoult's law, the solubility of a gas in water is proportional to its partial pressure and inversely proportional to its temperature. Therefore, in order to make the harmful gas absorbed and purified by water in the liquid and gas purifying equipment, it is most effective to increase the gas pressure of the gas and reduce the temperature of the gas and liquid. Secondly, depending on the physicochemical characteristics of the soot, to convert the soot from a gaseous state to a liquid state, one must destroy the surface chemistry of the soot particles, and the water particle size must match the particle size of the soot particles to provide an "affinity" for the surface tension.

Fifth, detailed description of the invention
As shown in fig. 1, the air pollution purifying apparatus includes a multi-stage purifying device, a feeding device and a precipitation separation device.
The multi-stage purification device comprises an air inlet chamber 1, a purification chamber 2 and an exhaust chamber which are communicated in sequence, wherein the cross-sectional areas of the air inlet chamber 1 and the exhaust chamber are smaller than that of the purification chamber 2. The intake chamber 1 is provided with an intake port 1 a.
As shown in fig. 2 and 3, the purification chamber 2 is partitioned by mesh-like partitions 3a, 3b, 3c into a plurality of purification zones 4a, 4b, 4c, 4d which are connected in series. The mesh-shaped partition plates 3a, 3b and 3c are arranged in the limiting grooves 12a and 12b on the upper wall and the lower wall of the purifying chamber 2, and can be disassembled, replaced and cleaned. The mesh on the baffle plate can be selected from 6 meshes to 120 meshes according to the property and the flow rate of the polluted gas to be treated. The liquid transport tubes 5a, 5b, 5c are provided at the upper part of the clean room 2, near the mesh-like partition plates 3a, 3b, 3c, and transport a liquid containing an acidic, basic or neutral surfactant. The liquid conveying pipe is provided with a spraying port 6 for spraying liquid to the mesh-shaped partition plate, and the surfactant can promote the liquid to quickly form a water film on the mesh-shaped partition plate. The spraying of different concentrations, viscosities and flow rates can be formed by changing the aperture of the spraying port 6. The lower part of the purification zone 4d is provided with a liquid discharge 10a, which discharge 10a is connected to the sedimentation separation device by means of a pipe 11.
In order to better realize the functions of induced air and exhaust and the convenience in manufacturing and installation, the exhaust chamber is formed by connecting two mutually communicated parts: a transition zone 7a communicating with the purification zone 4d of the purification chamber 2 and an induced air discharge zone 7 b. The induced air discharging area 7b is provided with an exhaust port 8, an exhaust fan 9 is arranged in the induced air discharging area, and the exhaust fan 9 is driven by a stepless speed regulating motor. The stepless speed regulating motor has the advantage that the rotation speed can be automatically regulated according to the requirement of exhaust.
The working process of the multistage purification device is as follows: (1) the polluting gases to be purified, such as the hot gases emitted by various boilers, are generally charged with CO, CO2、SO2、H2S, smoke dust and various other harmful substances, wherein the gas enters the gas inlet chamber 1 through the gas inlet 1a, slowly flows and is cooled and then enters the purifying chamber 2, and the gas is purifiedThe cross-sectional area of the gasification chamber 2 is larger than that of the gas inlet chamber 1, and the flow speed of the gas is further slowed down.
(2) The gas entering the purifying chamber 2 is filtered and cooled by a mesh-shaped partition plate 3a in a purifying area 4a, coarse and heavy particles are firstly settled, and the adhered surfactant falls to the bottom of the purifying chamber 2; the gas then enters the cleaning zone 4b and passes through the mesh-like partition 3b, the surface active substance continues to adhere to the finer particles in the gas and falls to the bottom of the cleaning chamber 2, at which point most of the dust and dirt has been removed. In the purification zone 4c, the temperature of the gas can be controlled below 60 ℃ by controlling the cooling circulation rateThe body is further filtered and settled by a mesh-shaped partition plate 3 c. At the same time, CO in the gas2、SO2、SO3、H2S, and the like, and reacts with sprayed water:
when the gas enters the purification area 4d, the gas does not contain dust and harmful substances, and is completely purified, so that the emission requirement is met. The liquid which descends to the bottom of the clean room 2 in the above process carries dust, dirt and reaction products such as H2CO3、H2SO4、H2SO48H, from the liquid discharge port 10a through the pipe 11 into the precipitation separation device.
(3) Due to the multi-stage continuous process through the purification chamber 2, the gas flow rate has dropped considerably to 1/2 of the original flow rate and has begun to block the gas flow in the gas inlet chamber 1. At this time, since the cross-sectional area of the exhaust chamber transition area 7a is smaller than that of the purification chamber 2, the velocity of the gas can be increased, and the gas enters the induced air discharge area 7b and is discharged from the exhaust port 8. Because the exhaust fan 9 is driven by the stepless speed regulating motor and arranged in the induced air discharging area, the flow velocity of the gas is promoted and compensated, and the uniform and smooth discharging process is ensured. The harmful humic substances in the discharged gas are greatly reduced, and the damage degree to the equipment is greatly reduced when the temperature is reduced to below 50 ℃.
The charging device is used for providing chemical reactants for treatment, CaO and water are respectively added into a charging pool 14 from material ports 13a and 13b, and Ca (OH) is generated through pool reaction2，Ca(OH)2Is fed to the precipitation separation unit via line 15.
The sedimentation separation device comprises a reaction tank 16, a reflux tank 17 and a filter tank 18 which are communicated in turn. The liquid from the purification device and Ca (OH) from the feeding device2After filtration through the screen 19, the reaction is carried out in the reaction tank 16:
CaCO as a product thereof3、CaSO4And is discharged from the discharge port 20 a. The liquid is further precipitated by the reflux pool 17, and the precipitate is discharged from the discharge port 20 b. The structure of the flow cell 17 is shown in fig. 4, and is separated into curved groove shape by a baffle plate to make the liquid flow slowly and precipitate the impurities. The liquid from the rotary flow tank 17 passes through the filter tank 18, and the impurities in the tank are discharged from a discharge port 20 c. The liquid flowing out of the filter tank 18 passes through waterThe pump 21 and the circulation duct 22 can circulate the infusion tubes 5a, 5b, 5 c.
CaCO discharged from the discharge ports 20a, 20b, and 20c3、CaSO4Can be reused in industry: CaSO4, i.e., gypsum or calcined gypsum, is useful as a filler for paper, white paint, buffing powder, gas drying agent, etc., and is useful in metallurgy and agriculture; CaCO3I.e. calcium carbonate (limestone), for the manufacture of cement, ceramics, lime, chalk, pigments, fillers, neutralizers, polishes, etc., and, in addition, is the simplest, practical and convenientThe cement is used as a cement filler for building and road construction.
