Energy-saving environmentally-friendly smoke afterheat recovering boiler

Abstract

An energy-saving environmentally-friendly smoke afterheat recovering boiler effectively solves the problems that smoke of a boiler is hard to treat and the purifying efficiency of liquid in a purifying device gradually decreases. The energy-saving environmentally-friendly smoke afterheat recovering boiler is characterized in that a water inlet pipe is arranged at the left side of a box body and communicates with the box body, wherein a slide rail is arranged in the box body and is positioned at an opening of the water inlet pipe; a baffle plate which can leftwards and rightwards move is arranged in the slide rail; the lower end of the baffle plate extends out of the slide rail; a concave groove which is positioned at the lower part of the water inlet pipe is formed in the left side of the box body; a spring is arranged in the concave groove, and the end part of the spring is fixedly connected to the lower end of the baffle plate. According to the energy-saving environmentally-friendly smoke afterheat recovering boiler, the smoke can be filtered through a solution in the box body; an alkaline solution is added through an agent adding pipe to remove heavy metal in the smoke, thus the heavy metal is prevented from being exhausted to the air to damage the body health of people; and meanwhile, dust particles in smoke can be filtered; domestic water flows into the box body through a cold water flow-in pipe, and a large number of heat in the smoke exchanges with the domestic water in a heat exchanging pipe through the solution in the box body; in addition, the liquid in the box body can be replaced, thus the cleaning efficiency is improved; and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of boiler energy saving, in particular to an energy-saving and environment-friendly flue gas waste heat recovery boiler. Background technique [0002] At present, industries such as chemical industry, building materials, printing and dyeing, food and hotels use boilers to generate heat for product production, and the fuel used by boilers is coal, gas and oil as raw materials. It is not allowed to burn if it does not meet the environmental protection requirements, and the cost of burning gas is high. Many companies use oil as fuel, and oil is divided into heavy oil and diesel. [0003] The fuel oil of the oil-fired boiler is pressed into the fuel injection nozzle by the high-pressure oil pump and sprayed out, mixed with the air sent by the blower and burned in the furnace, and the combustion temperature is generally 800-1000 ° C. After the high-temperature flue gas absorbs heat through the heating surface of the inner...
