Sampler Cooler
I. Product Overview
Cooling取样 cooler for water and steamFor power plant, steel smelting, chemical, textile, dyeing and printing, and boiler rooms, water and steam sampling cooling and testing are used. Product series include: steam sampling cooler, boiler water sampling cooler, make-up water sampling cooler, condensate sampling cooler, and blowdown sampling cooler. Water and steam in boilers and thermal systems are usually at high temperatures, which are not conducive to sampling and measurement. Sampling coolers can cool boiler water down to (30-40°C) and convert steam into water, then cool it down to (30-40°C), facilitating safe sampling by operators and achieving the cooling medium temperature below 30-40°C to meet the standard DL/T 457-91 of the People's Republic of China's power industry, and meet the requirements for sampling and testing.
II. Technical Requirements
1. The coolant flow rate of the sampling cooler is 500-700mL/min, and the cooling medium temperature can be reduced below 30°C.
2. The cooling tubes of the sampling cooler are all made of stainless steel pipes, carbon steel or copper pipes cannot be used to prevent the sample from being contaminated by the metal corrosion products of the cooling tubes.
3. The cooling tubes of the sampling cooler can be designed as a single coil or a double coil (designed based on medium parameters and installation space).
4. The Sampling Cooler is designed for sampling high-temperature liquids and gases, featuring a compact structure, high heat transfer efficiency, easy cleaning, and long service life. The sampling tube employs a spiral serpentine coil structure and is made of stainless steel, offering high-temperature resistance, corrosion resistance, long service life, and non-contamination of the sample. Depending on the distribution and concentration of the sampling points, it is designed to accommodate either a single Sampling Cooler or a modular Sampling Cooler, facilitating simultaneous sampling of steam, boiler water, condensate, make-up water, and deaerator outlet water.
