Rotary air-cooled smoke cooling device

Abstract

The invention relates to a smoke cooling device, in particular to a rotary air-cooled smoke cooling device which can cool smoke rapidly without a high pressure liquid circuit, a high pressure gas circuit or additional smoke moisture. The rotary air-cooled smoke cooling device mainly solves the technical problems of large volume, high manufacturing cost, complex structure, high running expense, high failure rate and the like in the existing smoke cooling device. The technical scheme provided by the invention is as follows: the rotary air-cooled smoke cooling device is of a box structure; a flat pipe rotation funnel is arranged in a shell of a box and is connected with the box through a connecting plate; a smoke inlet is arranged at one end of the flat pipe rotation funnel; a smoke outlet is arranged at the other end of the flat pipe rotation funnel; an air outlet is arranged at the upper part of the box and is connected with an air draft cooling fan; air induced by the air draft cooling fan is passed through base plate air inlets which are arranged in multiple rows at intervals in the funnel, so as to be entered the box; two surfaces of the flat pipe rotation funnel are respectively single-layer thin plates; the outside thin plate is provided with cooling fins which are connected with the outside thin plate and are arranged at intervals; the surface of the cooling fins in contact with air are subjected to roughening; and an ash cleaning hole is arranged at the bottom of the flat pipe rotation funnel and is provided with a cover plate. The rotary air-cooled smoke cooling device provided by the invention mainly applies to cooling smoke in incinerators.

Description

technical field [0001] The invention relates to a flue gas cooling device, in particular to a cyclone air-cooled flue gas cooling device which can quickly cool the flue gas without increasing the humidity of the flue gas without a high-pressure liquid circuit or a high-pressure gas circuit. Background technique [0002] At present, flue gas cooling devices at home and abroad are divided into: tube-type water-cooled flue gas cooling devices, semi-dry flue gas cooling devices, and heat pipe type flue gas cooling devices. [0003] Tube-type water-cooled flue gas cooling device: the flue gas flows through the tubes, the circulating water flows outside the tubes, and the cooling water and high-temperature flue gas exchange heat through the tube wall to achieve the purpose of cooling the high-temperature flue gas. This kind of device needs to be equipped with a large capacity and area of ​​the reservoir and heat dissipation pool, as well as auxiliary facilities such as high-pressu...
