Installation instructions for mobile coal powder sampler and coal powder sampling device:

The installation and operation of the coal powder sampler and mobile coal powder sampler of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. drill holes on the flue, extend the sampling tube into the flue, and make the sampling head face the direction of the incoming smoke flow. (Depending on the situation, the manufacturer can provide their own anti wear sleeve) Weld the sealing flange to the flue and ensure sealing with the sampling pipe. Connect the sampling tube to the cyclone collector with a nut. Connect the cyclone collector to the outlet pipe and valve, and then connect the sampling system to a certain position behind the baffle plate of the induced draft fan through a conduit (i.e. open a hole here. Weld the conduit). Insulate the sampling system (outside the flue) and the entire collector to prevent condensation from blocking the pipeline after sampling.

Mobile coal powder sampler, coal powder sampling device working process:

After the smoke flow enters the sampling nozzle, it passes through the sampling tube and enters the cyclone separator along the tangential direction of the wall. Rotate upwards and downwards along the wall of the device. During the rotation process, the fly ash is thrown onto the device wall due to inertial force, and falls into the ash collection hopper along the device wall through force, entering the sampling bottle, while the gas is discharged through the outlet pipe. When the flue gas flow rate is within the range of 6m/s-14m/s and the constant velocity sampling rate is greater than 95%, the sampler can also be powered by an air pump and can operate intermittently. Within the range of 70% of the unit load, it has the function of constant velocity adjustment. Reliable operation, convenient operation, and requires human maintenance. Mobile coal powder sampler - generally installed on the flue of the air preheater. If the flue width is greater than 2m, two samplers should be symmetrically installed on the flue. If the width is less than 2m, only one sampler should be installed. The pipe joints used for connection type transition are all equipped with water heating equipment- Some movable joints should be installed between them for easy disassembly and assembly, and welding parts should be minimized as much as possible. Connection welding requirements - closed.
