Energy-saving type coal-fired boiler with water scale removal function

Abstract

The invention relates to an energy-saving type coal-fired boiler with a water scale removal function. The energy-saving type coal-fired boiler with the water scale removal function comprises a main body, a water tank and a heating chamber, and further comprises a waste heat recovery mechanism and a descaling mechanism, wherein the descaling mechanism comprises a first motor, a screw rod, a slidingblock, a scraping plate and two connecting rods, the waste heat recovery mechanism comprises an air storage chamber and an air injection assembly, the air injection assembly comprises two driving units and two air injection units, and each air injection unit comprises a connecting box, a hose and six nozzles. According to the energy-saving coal-fired boiler with the water scale removal function,through descaling work, the descaling work can be carried out on the inner wall of the water tank, the situation that the water scale adhere to the inner wall of the water tank is avoided, and the heat conduction efficiency of the water tank is influenced; and through the waste heat recovery mechanism, high-temperature waste gas generated when the water tank in the heating chamber is heated can beguided into the nozzles to carry out heating and heat insulation work on the water tank, the situation that the high-temperature waste gas is directly discharged into the atmosphere is avoided, the energy is wasted, and the energy-saving property of the equipment is improved.

Description

technical field [0001] The invention relates to the field of energy-saving equipment, in particular to an energy-saving coal-fired boiler with scale removal function. Background technique [0002] A coal-fired boiler is a boiler whose fuel is coal-fired. It refers to the burning of coal in the furnace, releasing heat, heating the heat medium, heat medium water or other organic heat carriers (such as heat transfer oil, etc.) to a certain temperature (or Pressure) thermal power equipment, often used in people's daily life heating. [0003] After the existing coal-fired boiler works for a long time, the scale is easy to adhere to the inner wall of the water tank, which reduces the heat conduction efficiency of the water tank, thereby reducing the utilization rate of energy. Not only that, if the high-temperature exhaust gas generated by heating in the heating chamber is directly discharged into the atmosphere, wasting a lot of heat energy, reducing the energy saving and enviro...

[0003] After the existing coal-fired boiler works for a long time, the scale is easy to adhere to the inner wall of the water tank, which reduces the heat conduction efficiency of the water tank, thereby reducing the utilization rate of energy. Not only that, if the high-temperature exhaust gas generated by heating in the heating chamber is directly discharged into the atmosphere, wasting a lot of heat energy, reducing the energy saving and environmental protection of coal-fired boilers, thus greatly reducing the practicability of coal-fired boilers
