The role of electric coke capture in a gas stove ?? Urgent!!

1st Floor Electric coke preference equipment is one of the equipment used by the gas generator to filter the tar contained in the gas, and it is one of the purification equipment of the gas station. The structure of electric coke preserving equipment is various, but as a common shape, there are three kinds of concentric circle type, tube type and honeycomb type, no matter which kind of form of structure, its working principle, that is, between the metal wire and the metal pipe wall or the plate, the high-voltage direct current is applied to maintain the electric field sufficient to ionize the gas, so that the corona zone is formed between the cathode and the anode.

Structural analysis of the follow-up equipment of the gas generator electric coke capture equipment and the analysis and comparison of several kinds of electric coke capture:

Concentric circle electric tar precipitator. It is composed of several steel plate cylinders of different diameters, with the same vertical axis as the center of the circle, and the same spacing is sleeved together to form a precipitation pole. Due to the repulsion of the same sex between the corona poles, the electric field will appear as vacant small cavities, i.e., field strength caves.

It is easy to cause gas short-circuit loss in the cave, reduce the capture effect, at the same time, the manufacturing accuracy of the concentric circle electric tar precipitator is high, the installation and commissioning are extremely strict, and it is easy to make the concentricity, horizontality and verticality change in the manufacturing, installation and transportation, which will cause the discharge phenomenon between the cathode and anode or other components, and it is difficult to reach the required voltage, which directly affects the capture efficiency of the tar, and is also easy to make the electric porcelain bottle break down and destroy. Since the voltage change value of the field strength is 400V mm, even if there is a 1mm deviation between the cathode and cathode, the change value of the field strength voltage can be as high as 400V. The concentric circle electric tar precipitator has the advantages of large flow area, low gas flow rate and less steel consumption.

Tubular electric tar precipitator. Since the steel pipe and the corona wire form an electric field alone, its field strength voltage depends on the radius of the steel pipe, and its value is 400r. Because the tubular electric tar precipitator forms an equipolar spacing electric field in each tube section, and there is a vacancy between the tubes, these holes are blocked by the blind area of the tube sheet, which reduces the utilization rate of the effective space in the cylinder and reduces the cross-sectional area of the purification channel.

The steel consumption of this type of electric tar precipitator is large, but it has the advantages of easy manufacturing, equal pole spacing electric field, easy availability of materials and convenient installation and commissioning. It is widely used in large and medium-sized gas purification plants.

Honeycomb electric tar precipitator. The structure of the honeycomb type is the same as that of the tubular type, and the cross-section of the channel is changed from a circular to a regular hexagon. Two adjacent regular hexagons share one edge, i.e., the six sides of the regular hexagon in the middle are all shared by the six regular hexagons surrounding it.

Honeycomb panels made of 2 3mm steel plates can meet the requirements of process and mechanical strength. Because the honeycomb electric tar precipitator has the advantages of compact and reasonable structure, no electric field holes, high effective space utilization, light weight, less steel consumption and good capture characteristics, but there are shortcomings such as difficult manufacturing and easy to produce errors in the process of transportation and installation. With the improvement of the level of equipment manufacturing technology, the advantages of honeycomb electric tar precipitator will be more and more valued by people, and will gradually replace concentric circle and tubular electric tar precipitator.

The cold gas produced by the gas station built by the gas generator must be processed by the tar plant. After treatment, the gas will no longer contain large quantities.

What do you want?

1. After the coal is gasified, the coarse gas formed contains many impurities, such as tar, dust, moisture, benzene, naphthalene, ammonia, sulfur and other components. Due to the presence of these impurities, the pressure transportation of gas and the quality of products using gas as fuel or raw material will have a very serious impact, so the purification of gas is an indispensable part of the gas production process.

2. The purification of gas is to use purification equipment to filter out or remove impurities in the gas, improve the cleanliness of the gas, and provide qualified gas.

3. Classification of gas purification methods.

1) Coarse purification: vertical pipes, horizontal pipes, and scrubbers are commonly used as primary cooling and dust removal equipment, with a dust removal efficiency of 70-80%, a decoking efficiency of only 20-30%, and a dust content concentration of 1-10g cubic meters.

2) Semi-precision purification: multi-use cyclone dust collector, it can only purify the large particles in the gas, and the dust content concentration in the gas after treatment is cubic.

3) Precision purification: using an electric tar precipitator, the dust concentration in the treated gas is 10-30mg cubic meters.

Electric tar precipitator Hubei Jingtian environmental protection They are quite professional, scope of application:

It is mainly used for gas purification in chemical fertilizer, coking, city gas, metallurgy, building materials, carbon, ceramics and other industries, and is used to remove tar in coal gas and coke oven gas, and at the same time remove dust, water mist and other impurities, so as to achieve the dual effect of material and gas purification, which also plays a vital role in ensuring the normal and stable operation of equipment in the rear section of the process.

Health is your own, it depends on the cost performance of the purifier, the parameters to be considered rather than the advertisement, whether the HEPA high-efficiency particulate filter can effectively catch particles with a diameter of less than microns This is the key? How many kinds of suspended particulate matter can be filtered, preferably particles with a diameter of about equal to microns (it must be filtered, and it also contains many viruses and bacteria, such as pertussis bacillus particles are microns in diameter, E. coli bacteriophage particles are microns in diameter, swine flu particles are microns in diameter, hand, foot and mouth disease particles are in microns, and mites are in diameter? Is it possible to automatically detect and indicate when the filter needs to be replaced?

It also depends on whether there is a certification from an authoritative organization?

Gas generator, electric coke capture, and electric light capture are the three main parts of the gas generator, and the relationship between them is independent of each other. Therefore, they can be tested at the same time, but separately. The power test of the gas generator furnace is mainly to detect whether the electrodes in the furnace are working normally, and whether there are problems such as leakage in the furnace.

The test power test of electric coke capture and electric capture light is mainly to detect whether the electrode is working normally, and whether there is leakage. It should be noted that the power supply must be cut off and safety must be ensured before the power test is carried out. At the same time, professional electrical testing instruments need to be used in the process of power testing, and operated by professionals!

My gas stove has been producing gas for half a month, can the electric coke capture be turned on directly? Or how to do it.

Hello, wait a minute.

Do I need to turn off the steam after ventilation?

1.Before charging and running, the upper jacket should be filled with steam and preheated the high-voltage insulation part for more than 10 minutes or reach the specified temperature index (to avoid condensate affecting the insulation effect), and the oxygen content should not exceed 05% of the time when the high voltage is put into operation.

2.During the operation of the equipment, the lower heating steam coil must be opened to ensure the smooth discharge of tar. 3.

After the power failure, the capacitors in the tower must be discharged 4When the oxygen content exceeds the above, the high-voltage power supply should be cut off, and when the oxygen content is below, the high-voltage power should be put into operation.

Hello, you need to check whether the gas inlet, outlet valve, and discharge pipe valve are in a closed state before use. Check that the explosion-proof cover of the electrofishing is open. After the above inspection is normal, open the inlet and outlet valves of two insulated boxes and one insulated steam insulated by electric capture, so that the temperature of the insulated box rises uniformly to 90 110 (when the temperature is lower than 90, it is not allowed to be turned on).
