Problems solved by technology

[0003] However, in the process of internal combustion engine power generation, the temperature of the flue gas discharged from the internal combustion engine after combustion is about 550°C, and the heat energy converted by the gas through combustion for power generation is only 35%, and the heat taken away by the generated flue gas is the combustion heat of the gas. 60% of the value, but most enterprises do not use the heat energy in the flue gas, thus wasting a lot of energy

Embodiment Construction

[0013] As shown in the figure: a high-efficiency energy-saving waste heat recovery evaporator is composed of a steam drum, a heat pipe and a smoke box. The cold end of the heat pipe is in the pressure vessel and is sealed and firmly connected with the pressure vessel. The hot end of the heat pipe is in the smoke box, and the entrance of the smoke box is connected with the bypass of the kiln exhaust flue, and a smoke inlet damper is installed on the connected pipeline. . The outlet of the smoke box is connected with the induced draft fan. During operation, the main flue gate of the kiln is closed, the exhaust gas passes through the smoke box, and the heat pipe is heated, and the soft water in the pressure vessel is heated to generate steam by the principle of phase change heat transfer of the heat pipe. The main flue gate is also installed at the main flue of the kiln between the two gates.

[0014] The specific working process of the device is as follows: firstly open the sm...

Abstract

The invention discloses a heat pipe waste heat boiler which is composed of a pressure vessel, a heat pipe and a smoke box, wherein a cold end of the heat pipe is arranged in the pressure vessel and is fixedly connected with the pressure vessel in a sealed mode; a hot end of the heat pipe is arranged in the smoke box; an inlet of the smoke box is connected with a bypass of a furnace exhaust flue, and an outlet of the smoke box is connected with a draught fan. The heat pipe waste heat boiler is easy to operate, stable and reliable in operation, the product produced by using the boiler has stable quality and effectively improves the utilization ratio of the flue gas.

Description

Technical field: [0001] The invention belongs to heat energy recovery equipment, in particular to a heat pipe type waste heat boiler. Background technique: [0002] With my country's accession to the WTO, in order to better reduce carbon dioxide and achieve a low-carbon life, my country has increased sewage treatment in recent years to generate biogas, and then uses biogas to generate electricity through internal combustion engines; Emissions are also changed to burning electricity through the internal combustion engine. [0003] However, in the process of internal combustion engine power generation, the temperature of the flue gas discharged from the internal combustion engine after combustion is about 550°C, and the heat energy converted by the gas through combustion for power generation is only 35%, and the heat carried away by the generated flue gas is the combustion heat of the gas. 60% of the value, but most enterprises do not use the heat energy in the flue gas, thus ...
