How black smoke from a boiler turns into white smoke through water

The black smoke passes through the water film dust collector, commonly known as the granite dust collector, and turns from black smoke to white smoke.

The basic principle of water film dust collector and centrifugal cyclone dust collector.

Basically the same, the difference is that some water pipes are arranged on the inner wall of the dust collector, so that the water flows from the inner wall of the stone from top to bottom, and the dust particles are separated outward under the centrifugal action, and when the large and small dust particles are in contact with the water, the weight increases to form a trapping effect, and then these dust particles go down the water and are separated at the bottom of the dust collector.

It's dusting. If the resistance loss is too large when it is directly connected to the pool, it can be designed as a simple venturi dust collector. Add a baffle to the pool so that there is a small gap between the baffle and the water surface, and let the smoke pass through this gap. Pay attention to the sludge discharge and treatment of the pool water.

Black smoke purification principle:

1. Water purification, sewage purification and recycling.

2. Add desulfurization and sewage purification agent appropriately in the sewage pool.

3. When burning coal or firewood (plywood scraps), it is necessary to cooperate with the black smoke treatment method provided by our company, so that the black smoke is sent into the equipment (or inhaled) by the induced draft fan after pyrolysis for cooling and dust removal, and the cracked flue gas is cleaned by the high-pressure water in the equipment, so that the flue gas and water are fully mixed and decomposed, desulfurized and purified, and then the water mist is filtered, and the discharged flue gas becomes a white flue gas with water vapor, which meets the national emission standards after testing.

After the black smoke of the boiler passes through the water film dust collector, it desulfurizes and removes the smoke and dust, and the white water vapor is emitted.

Hello, the following is the operation method of turning the black smoke of the boiler into white smoke through the water:1The flue gas enters the flue gas purifier, and the water mist is sprayed into the flue gas through the large jet water sprayer.

2.The solid particles and liquids in the flue gas come into contact with the water mist and are adsorbed to the surface of the water droplets to form suspended solid or liquid particles, as well as fine droplets. 3.

Suspended solids and liquids aggregate on the surface of the water droplets to form larger particles and gradually settle into the water. 4.Gaseous contaminants are also adsorbed to the surface of water droplets through contact with water mist and then dissolved in water.

5.The cleaned flue gas is fed into the dust collector to achieve the effect of purification. In the above process, water mist is added to the flue gas to make it come into contact with solid, liquid or gaseous pollutants, thereby adsorbing the substance, reducing the emission of black smoke and making it easier to remove pollutants in the flue gas.

After these treatments, the black smoke is gradually removed and converted into white smoke emissions.

Summary. Hello <>

How the black smoke from the boiler turns into white smoke through the water, the black smoke emitted from the boiler is mainly caused by the incomplete combustion of the fuel. When fuel is burned in a boiler, a large amount of heat energy is generated, part of which is transferred to the water, causing the water vapor to turn into water vapor, while the other part of the heat energy is taken away and discharged into the atmosphere in the flue of the boiler. In order to reduce the emission of black smoke, good boiler conditioning and maintenance are required to ensure that the fuel is fully combusted.

In addition, a wet dust collector can also be installed in the flue gas discharged by the boiler to combine the flue gas with water spray, so that the particles and pollutants in the flue gas can be precipitated through the scouring action of water mist, so as to achieve the purpose of purifying the flue gas.

Hello <>

How the black smoke from the boiler turns into white smoke through the water, the black smoke emitted from the boiler is mainly caused by the incomplete combustion of the fuel. When the fuel is burned in the boiler, a large amount of heat energy will be generated, part of which is transferred to the water, so that the water vapor is converted into water vapor, and the other part of the heat energy will be taken away for combustion and discharged into the atmosphere in the flue of the boiler. In order to reduce the emission of black smoke, good boiler conditioning and maintenance are required to ensure that the fuel is fully combusted.

In addition, a wet dust collector can also be installed in the flue gas discharged by the boiler to combine the flue gas with water spray, so that the particulate matter and pollutants in the flue gas can be precipitated through the scouring action of water mist, so as to achieve the purpose of purifying the flue gas.

When the flue gas emitted by the pot potato is full of particulate matter, sulfide and other pollutants, these pollutants will cause great harm to the environment and human health. Therefore, in the boiler industry, it is very necessary to take effective purification measures. Wet dust collector is a common purification equipment, which adsorbs the particulate matter and digital pollutants in the flue gas by spraying the water curtain, so as to achieve the purpose of purifying the flue gas.

At the same time, other purification measures, such as electrostatic precipitation, desulfurization and other technologies, can also be used to reduce the pollutants emitted by the boiler. In addition, when choosing a boiler supplier, it is also necessary to pay attention to the environmental performance of its products, choose high-efficiency boiler products that meet national environmental protection standards, and contribute to environmental protection. <>

There are generally two reasons for black smoke from boilers: insufficient fuel combustion and failure during the dust removal period, the former is caused by too much fuel moisture or insufficient air delivery, and the latter needs to be repaired or replaced by the dust collector. If you must use water to filter, and the resistance loss of flue gas directly into the pool is too large, you can add a baffle on the pool, leaving a gap between the baffle and the water surface, and the smoke can be discharged directly from the gap.

Instructions for black smoke.

There are a lot of combustibles that don't.

Du burns, and the black smoke is mainly carbon black, coal dao particles, etc., indicating that the burning plate is not completely burned and the waste is serious. Impersonation.

White smoke indicates sufficient combustion and reduced waste. White smoke can be seen directly in winter, this white smoke is mainly water vapor, which condenses with low temperature to form fog without the cover of black smoke, and what we see is white smoke.

1. The flammable gas produced by the decomposition of organic matter at a certain temperature and under certain conditions in the combustion of coal burned by the boiler is called "volatile matter", which is a mixed gas composed of various hydrocarbons, hydrogen, carbon monoxide and other compounds. Volatile matter is also the main coal quality index, and it has an important reference role in determining the processing and utilization methods and process conditions of coal. Coal with a low degree of coalification has more volatile matter.

If the combustion conditions are not appropriate, coal with high volatile content is easy to produce unburned carbon particles when burned, commonly known as "black smoke";

2. "Black smoke" contains carbon monoxide, water vapor, etc.; The flue gas produced by coal-fired boilers contains inadequately burned coal particles and ash particles, resulting in soot pollution. In order to control soot pollution, coal-fired boilers are generally equipped with dust removal facilities and dust content detectors, and the boiler chimneys that purify the flue gas will emit "white smoke";

The content of inorganic substances in coal is very small, mainly water and minerals, and their presence reduces the quality and utilization value of coal. Minerals are the main impurities of coal, such as sulfides, sulfates, carbonates, etc., most of which are harmful components.

"Black smoke" is converted into nitrogen oxides and ammonia at high temperatures, which are precipitated in a free state. Sulfur, phosphorus, fluorine, chlorine and arsenic are harmful components in coal, with sulfur being the most important. When coal is burned, most of the sulfur is oxidized into sulfur dioxide (SO2), which is emitted with flue gas, polluting the atmosphere, endangering the growth of animals and plants and human health, and corroding metal equipment; When sulfur-rich coal is used for metallurgical coking, it also affects the quality of coke and steel.

Therefore, the "sulfur" content is one of the important indicators to evaluate the quality of coal.

Black smoke is extremely polluting to the environment. White smoke is treated after staticing. However, white smoke also has a certain amount of emissions, which is less polluting to the environment than black smoke.

For black smoke, a wet purifier can be used.

The main structure is made of corrosion-resistant stainless steel. The product uses original advanced technology, using corrugated inclined plate packing, the fan and the purifier are connected, the use of aerodynamics, in the precision design of the integrated structure, due to the force of the fan, the purifier will produce agitated, boiling water layer and multi-layer water film. The black smoke (dust) can be thoroughly purified after three water purification treatments and three mechanical purification treatments, by comprehensively using the principles of water vapor reverse impact, washing, water film filtration, foam absorption, enrichment, multiple mechanical collisions, interception, dropping, condensation, and efficient adsorption.

However, when choosing a purifier, you must have professional knowledge to choose according to the air volume, efficiency, and power.

The black smoke produced by the boiler needs to be treated with special environmental protection equipment.

The electrostatic precipitator has been applied to the smoke and dust purification of industrial boilers for more than ten years, and the industrial application in China has been about 40 years, the black smoke enters the electromagnetic field in the electrostatic precipitator through the pipeline, due to the mutual adsorption of the positively charged smoke and the cathode electric plate, the particle smoke in the flue gas is adsorbed on the cathode, and the cathode plate is hit regularly, so that the smoke and dust with a certain thickness fall in the ash hopper under the structure of the electrostatic precipitator under the dual role of self-weight and vibration, so as to achieve the purpose of removing the smoke and dust in the flue gas.

Electrostatic precipitators are also widely used:

1. Coal-fired boilers for industry and heating, heavy oil boilers.

2. Building materials: dry and wet cement rotary kiln, machine vertical kiln, raw and clinker mill, raw material dryer and cement packaging machine.

3. Non-ferrous smelting: copper, lead, zinc sintering, copper smelting furnace, electric arc furnace, reverberatory furnace, etc.

4. Metallurgy: iron ore sintering machine (head and tail), blast furnace, open hearth, coke oven, converter, electric arc furnace and refractory industry.

To deal with the black smoke generated by the boiler, it is best to go to a special environmental protection company and inspect the site to formulate a treatment plan in order to effectively deal with it.
