Product Description

Ceramic double casing, ceramic turbulence double casing using high-tech production process - self-combustion high temperature synthesis of the law. The tube consists of three layers of corundum ceramic, transition layer and steel from the inside to the outside. The ceramic layer forms dense corundum porcelain (AL2O3) at a temperature above 2200 ℃ and forms a firm bond with the steel pipe through the transition layer.

Due to the high strength steel tube, good toughness, impact resistance, good welding performance and corundum porcelain high hardness, high wear resistance, corrosion resistance, heat resistance, to overcome the low hardness of steel, wear resistance and poor ceramic toughness characteristics .this, the composite pipe has a good wear resistance, heat resistance, corrosion resistance and mechanical shock and thermal shock, good weldability and other comprehensive performance. It is the ideal wear-resistant and corrosion-resistant pipe for conveying granular materials, grinding and corrosive media. Now widely used in electric power, mining, steel, cement, chemicals and other wear-like industries. The current model straight pipe, elbows, elbows, tees, head size, the other can produce pants tube, the use of the effect is very good.

Can replace the alloy tube, cast iron and so on. As the tube is wear-resistant, corrosion-resistant, heat-resistant, this can be widely used in power, metallurgy, mining, coal, chemical and other industries as conveying sand, stone, coal, ash, Corrosive media, is an ideal wear-resistant pipe. Metallurgy, power industry applications: Metallurgy, power industry, transportation of pulverized coal, ash, mud, lime gypsum slurry, etc. need to consume a large number of metal pipes each year. Ceramic composite pipe to replace other pipes, with high wear resistance, long life, easy installation, significant economic benefits.

The double bushing is composed of a main conveying pipe and an inner bypass pipe which is fixed on the top of the inner wall of the double bushing. The bottom of the inner bypass pipe is provided with an opening at every certain interval in the axial direction. When ash deposition occurs somewhere in the main pipe, the pressure drop at the sediment section increases drastically and the mixed gas-ash flow is forced to flow into the inner bypass pipe and again flows out from the next opening at a higher velocity The main pipe, and in the material section of the formation of turbulence, the material section of the pile blows. The flow of ash mixture into and out of the inner bypass pipe in the process of continuous ash in the repeat, dry ash section in the main pipe continuously divided, moving, blowing, the ash will continue to move forward. So that double casing in the pneumatic ash system to achieve low flow rate, high concentration turbulent stable ash operation.

Ceramic turbulence double sleeve is a further improvement made by our company on the basis of turbulent double casing, belonging to the domestic initiative. The product consists of the main delivery pipe and the internal bypass pipe fixed on the top of its inner wall. The internal bypass pipe There is a drainage - damping partition, the bottom along the axial direction according to the process requirements at an interval to set an opening, through the self-regulation of the transmission pipeline fly ash to achieve turbulent state of transport.

Ceramic turbulence double tube from the transport mechanism is different from the conventional positive pressure pneumatic conveying system, change the suspended transport for the static pressure transmission, thus changing the conventional positive pressure delivery of low concentration, high velocity, easy to wear, easy plugging It is an ideal solution to transport high abrasion, high output, dense phase conveying abrasion-resistant materials (such as boiler fly ash) and represents the advanced standard of ash removal technology today.

 

Product Features: 

1. System adaptability, high reliability:

Ceramic turbulence double casing system unique working principle to ensure that the ash system piping is not easy to block, even after a short shutdown and then start again, it can quickly clear, so as to ensure the safety and reliability of the ash removal system. This feature also determines the system is more widely applied to the transport of materials, especially elbow lime powder, bauxite and other difficult to convey the powder material than other ash removal system more perturbation; the ash removal system pressure changes Smooth, air compressor air supply fluctuations small, relatively stable system operating conditions, thus improving the operation of ash removal air compressor operating conditions, extend the service life of equipment, than the conventional single-tube pneumatic ash removal system performance is better.

2. Low flow rate, low wear rate:

The starting velocity of ash mixture in ceramic ash removal tube system is 2-6m / s, the final velocity is about 15m / s and the average velocity is 10m / s, while the initial velocity of dilute ash removal system is 10m / s ,, the final speed of about 30m / s, the average flow rate of about 20m / s. The amount of wear and conveying speed of the 3-4 power is proportional to the ceramic turbulence double pipe dust removal pipe wear 1 / 8-1 / 16 dilute phase ash, that is, the ceramic turbo dual-pipe system ash pipe life of 8-16 times the dilute phase system.

3 long life, low energy consumption:

Due to the low velocity and wear of the mixture of ash and gas in the turbulent double-tube ash removal system, the ceramic pipe is adopted by our company, which can greatly reduce the investment and maintenance costs of the ash removal pipe. At the same time due to the high concentration of transport, the corresponding air consumption is also reduced, the top of the bag filter to reduce the filter area, equipment investment costs are reduced, while reducing equipment power, reduce energy consumption: Years of actual operation proved that the power consumption Than dilute phase pneumatic ash removal system 30% -50% lower. According to the statistics, the power consumption per unit of dilute phase pneumatic ash removal system is generally 7-10kW · h / (t · km), while the ceramic turbulence double casing system is generally 4-6kW · h / (t · km) As a result, annual operating costs are reduced.

4. Conveying output, transmission distance

Normally, the concentration decreases as the transport distance increases. System delivery will also be reduced. The ceramic turbulence double tube ash removal system output up to 100t / h or more, the transmission distance up to 1000m above, which is other pneumatic ash removal system is difficult to achieve.

The company is located in:
