Boiler waste gas treatment device convenient for recycling heat

Abstract

The invention relates to the technical field of boiler waste gas treatment, and discloses a boiler waste gas treatment device convenient for recycling heat, which comprises a filter chamber, a gas inlet pipe is fixedly communicated with one side in the filter chamber, the bottom end of the gas inlet pipe is hermetically inserted in a glass cover, and a filter element rod is plugged in the glass cover; the other side of the filter chamber is inserted with a gas transmission section connected with an air outlet pipe, the air outlet pipe further comprises a heat exchange section and an exhaust section, the heat exchange section is evenly wound on two heat exchange water bins, the two heat exchange water bins are directly connected through a connecting water pipe, an inner water flow channel of each heat exchange water bin is an interlayer of the bin wall, and flow blocking rings are evenly arranged on an interlayer support of the bin wall; and water holes are evenly formed in the flow blocking ring, the direction of water flow in the connecting water pipe is opposite to the direction of air flow in the air outlet pipe, waste gas exhausted by the boiler can be filtered, the filtered hot waste gas is subjected to heat exchange on the heat exchange water bin, and therefore heat of the waste gas is fully recycled.

Description

technical field [0001] The invention relates to the technical field of boiler exhaust gas treatment, in particular to a boiler exhaust gas treatment device that is convenient for heat recovery and utilization. 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 ...

Problems solved by technology

[0003] The flue gas produced by the boiler during the combustion process is directly discharged to the outside, causing air pollution, and the waste gas contains a large amount of heat, which is directly discharged and causes energy waste. For this reason, we have designed a boiler waste gas heat Recycling and reuse devices to solve the above problems
