Energy-saving and environmentally-friendly boiler for grand hotel

Abstract

The invention discloses an energy-saving and environmentally-friendly boiler for a grand hotel. The energy-saving and environmentally-friendly boiler for the grand hotel comprises a tower body, a water tank and a dust filtering box. A fire grate is arranged at the bottom of an inner cavity of the tower body, and the inner cavity of the tower body is divided by the fire grate into a combustion chamber and a boiler slag chamber. A pulverized coal nozzle is arranged at the bottom of one side wall of the combustion chamber, and the water tank is arranged on one side of the top wall of the combustion chamber. A separating plate is arranged in the water tank, a communicating hole is formed in the separating plate, and a first control valve is arranged in the communicating hole. An inner cavity of the water tank is divided by the separating plate into a preheating cavity and a heating cavity. A water addition pipe is connected with the top end of the preheating cavity in a penetrating mode, and a plurality of heat exchange pipes are uniformly arranged in the preheating cavity. A water outlet pipe is connected with the bottom end of one side end of the heating cavity in a penetrating mode,and a control valve is arranged on the water outlet pipe. The dust filtering box is arranged on the top of the right side end of the tower body, and a plurality of slag discharging holes are uniformly formed in the side end of the boiler slag chamber. By the adoption of the energy-saving and environmentally-friendly boiler for the grand hotel, high-temperature smoke and water in the preheating cavity conduct heat exchange through the heat exchange pipes, the water in the preheating cavity is heated, the temperature of the smoke is reduced, and therefore the waste heat of the exhaust gas can be reutilized, and the utilization efficiency of fuel coal can be improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to an energy-saving and environment-friendly boiler applied to large hotels. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers,...

AI Technical Summary

Problems solved by technology

[0005] The traditional hotel boiler equipment has very backward technology, low thermal efficiency, and high energy consumption, which makes the operating cost high, and the filtered smoke contains a large amount of floating dust, which affects the hotel kitchen environment.
