Vertical heat pipe waste heat boiler for chemical flue gas

Abstract

The invention relates to the technical field of waste heat boiler equipment, and discloses a vertical heat pipe waste heat boiler for chemical flue gas. The vertical heat pipe waste heat boiler comprises a waste heat boiler body, a heating water tank and a chimney, a waste heat flue gas leading-in pipe is fixedly connected to the top end of the waste heat boiler body, and a partition plate is fixedly connected to the middle of the interior of the waste heat boiler body; a first dust filter screen is installed on the upper side in the partition plate, a sliding frame is slidably connected to one end of the partition plate, dust inlet grooves are formed in the two sides of the top end of the sliding frame, and a driving motor is fixedly installed in the middle of the top end of the sliding frame; and a fan blade is fixedly connected to the output end of the driving motor, the fan blade is rotationally installed in the middle of the sliding frame, and a mounting cylinder is fixedly connected to the middle of the bottom end of the sliding frame. The vertical heat pipe waste heat boiler for the chemical flue gas can be cleaned regularly, the waste heat boiler does not need to be shut down to clean dust, normal use of the waste heat boiler is guaranteed, the situation that the boiler is shut down frequently due to ash deposition and coking blockage is avoided, and economic losses canbe reduced in the cleaning process of the waste heat boiler.

Description

technical field [0001] The invention relates to the technical field of waste heat boiler equipment, in particular to a chemical flue gas vertical heat pipe waste heat boiler. Background technique [0002] Waste heat boiler, as the name implies, refers to a boiler that uses waste heat in waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with smoke boxes and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery. The working principle of the waste heat boiler: fuel oil, gas and coal are burned to produce high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrote...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a chemical flue gas vertical heat pipe waste heat boiler, which can be cleaned regularly without shutting down the waste heat boiler to clean up dust, ensuring the normal use of the waste heat boiler, and eliminating the need to shut down the waste heat boiler. The waste heat boiler cleans up the dust, avoiding the frequent shutdown of the boiler due to ash accumulation and coking blockage, and also prevents the attached dust from being thick and troublesome to clean up. The cleaning process of the waste heat boiler can reduce economic losses and improve the efficiency of the waste heat boiler. The convenience of cleaning and other advantages solves the problem of regularly closing the boiler for manual cleaning in the cleaning method of most enterprises at present, which often causes the shutdown of the boiler due to ash accumulation and coking blockage, and manual cleaning of the heat exchange inner wall of the waste heat boiler The efficiency is relatively slow, and the waste heat boiler must be shut down to stop using, and the shutdown of the waste heat boiler will cause certain economic losses. The frequent shutdown of the waste heat boiler will have a certain impact on the use. If the inner wall of the waste heat boiler is not cleaned for a long time, it will not only improve the cleaning Difficulty, it will also cause certain damage to the equipment. At the same time, when the exhaust gas of the waste heat boiler is discharged, the flue gas emission efficiency cannot be guaranteed, which will affect the use of the waste heat boiler.
