How does a descaler work?
The decontamination device is composed of a filter body, a steering valve, a filter screen and a sewage outlet. The treated water enters the filter body through the water inlet, and impurities in the water will be trapped on the stainless steel filter. When the impurities are accumulated to a certain degree, the pressure difference between the inside and outside of the filter reaches the set value (≤0.05MPa), open the drain valve , Close the steering valve and start draining.
The decontaminator has a simple structure, low cost, is easy to install and operate, and requires almost no maintenance. The decontamination efficiency is high, the cleaning is convenient, and uninterrupted water supply can be provided during cleaning. It solves the difficult problem of the traditional swirling sand removal (dirt) device with small contrast weight, such as suspended solids, leaves, and paper scraps. It is mainly applicable to the water quality treatment and control of raw water and make-up water; such as: river water, well water, seawater sand removal, coal washing water, solid-liquid separation of industrial ore dressing, and non-mutual solution separation; it can be widely used in water source heat pump systems, heating water, Municipal heating, central air-conditioning cooling water, chilled water, steel, electric power, chemical and other industrial and mining enterprises, industrial circulating cooling water, tap water, seawater, surface water, groundwater, etc.
Process flow: raw water-decontamination-precision filtration-storage tank-user. The descaler is based on the principle of centrifugal sedimentation and density difference. When the water flow enters the device tangentially from the inlet under a certain pressure, a strong rotational movement occurs. Due to the different density of sand and water, the centrifugal force, centripetal buoyancy, fluid Due to the different forces under the action of the drag force, the low-density clean water rises and is discharged from the overflow port, and the dense sand is discharged from the bottom sand discharge port, thereby achieving the purpose of decontamination. Under a certain range and conditions, the greater the water inlet pressure, the higher the sand removal rate, and multiple units can be used in parallel.
Decontamination device is a widely used component in petrochemical process pipelines. One of its effects is to prevent impurities in the pipeline medium from entering the transmission equipment or precision parts, causing production failures or affecting the quality of the product. It is installed on the user's inlet water supply main, as well as the heat source (cold source), hot (cold) equipment, water pump, and the inlet of the regulating valve. The installation shall be carried out in accordance with the requirements of the engineering design instructions. If this equipment design system is selected without valves on the inlet and outlet pipes and disassembly is not required, the flanges on the inlet and outlet pipes should be cancelled, and the decontaminator and the pipes should be directly welded. After the equipment is installed, the debris left inside due to production or installation should be removed. During the operation, decontamination should be carried out regularly according to the cleanliness of the pipeline system to ensure the dredging of the decontamination device .
