Anti-blocking sampling bottle used in Daya Bay Nuclear Power Station
Daya Bay Nuclear Power Plant is located in Dapeng Peninsula [1-4] (22 ° 36′33.28 ″ north latitude, 114 ° 33′08.30 ″ east longitude) 51 km away from Hong Kong ’s Tsim Sha Tsui [2] It is jointly constructed and operated by Guangdong Nuclear Power Investment Co., Ltd. and Hong Kong Nuclear Power Investment Co., Ltd. [5]. It is under the jurisdiction of China National Nuclear Power Corporation. It has two million-kilowatt PWR units, and 70% of the electricity produced is supplied to Hong Kong. , 30% supply to Guangdong [6]. The Daya Bay Nuclear Power Plant started construction in 1987 [5] and was officially put into commercial operation on May 6, 1994 [4]. Since then, the Ling Ao Nuclear Power Station has been built on the side of the Daya Bay Nuclear Power Station. The two together form a large nuclear power base. Daya Bay Nuclear Power Station is the first large-scale commercial nuclear power plant in mainland China [3] [6-7], and the first nuclear power plant in mainland China built using foreign technology and funds.
The anti-blocking sampling bottle applied to the Daya Bay Nuclear Power Plant has been shipped in May 2018
Anti-blocking sampler / anti-blocking sampling bottle
Product model: JZ-FD series
I. Overview
The key problem of the anti-blocking sampler / anti-blocking sampling bottle to measure the air pressure or differential pressure of the gas containing dust is that the sampling device is blocked by the dust and the instrument cannot continue to operate normally. This is very detrimental to safe production and measurement accuracy, and in order to get it through The sampling device must be purged with compressed air or manually stabbed. This is undoubtedly a dirty and tiring task, and it adds a lot of maintenance work. This device is scientifically analyzed and cited under the strong demand for solving this headache. Developed under the pragmatic attitude of absorbing advanced and mature experience from abroad, carefully designing and strictly grasping the manufacturing quality. The anti-blocking wind pressure sampler has been proved by the long-term use experience of many domestic power plants. It can be used in the powder and powder conveying (coal powder) system and furnace for the measurement of wind pressure and differential pressure. It can receive the effect of never blocking once and for all. Of course it also It can be used in the measurement of wind pressure or differential pressure of cement, flour, metal powder and other gas containing solid particles.
When you are clogged for measuring high-viscosity, low-liquidity, and highly corrosive air-powder mixture, it is a big headache. Please contact our factory. We can design and manufacture a satisfactory anti-blocking sampler for you.
2. Working principle
Anti-blocking sampler / anti-blocking sampling bottle According to the principle of gas convection and the specific gravity of the material, our company has developed the most ideal anti-blocking wind pressure sampler in China. The dust-containing gas is measured through the lower end of the sampling cylinder, after three layers of special anti-blocking mechanisms, the layers of convection fall back, and the layers are separated to contain solid dust. The proportion of dust is greater than the gas. The dust falls to the cone end of the sampling cylinder until the sampling container , The purified gas can be measured correctly by the transmitter, so as to achieve the purpose of anti-blocking wind pressure sampling.
3. Characteristics of anti-blocking wind pressure sampler
The anti-blocking sampler / anti-blocking sampling bottle has the following advantages compared with the conventional ordinary sampler:
1. Simple structure and beautiful appearance;
2. No air source is needed, there is no problem of complicated system and large installation workload;
3. No energy consumption and maintenance;
4. No additional measurement errors;
5. The three-layer anti-blocking mechanism is divided into carbon steel and stainless steel. The stainless steel structure can greatly improve the service life of the product.
4. Anti-blocking sampler / anti-blocking sampling bottle installation requirements
1. The anti-blocking wind pressure sampler must be installed vertically.
2. When it is difficult to install vertically on the process pipeline or equipment directly, please connect the long sampling tube. The angle between the long tube and the horizontal plane should be greater than or equal to 60 °. The sampler body must still be installed vertically.
3. There should be no burrs or other irregularities on the edges of the pressure hole Ф32 (outer diameter Ф38 × 3).
4. Welding pressure tube must be free of any defects.
