Abstract
The utility model discloses a spiral heat exchange type air heater, characterized in that a spiral plate heat exchanging chamber and a burning chamber are connected in two-body type, the burning chamber is provided with a fire grate, an air inlet and a furnace door, and the outlet of a secondary burning chamber is provided with a flue conduit connected with the flue chamber of the spiral heat exchanging chamber. The spiral heat exchanging chamber is composed of two independent flue and hot air spiral channels by a metal double helix plate, and the flue channel of the flue chamber is provided with a flue discharge channel. The spiral channel which is adjacent to the flue discharge channel is a hot air channel, and an air inlet arranged outside the spiral channels is connected with the hot air channel. The utility model is characterized in low flue discharge temperature, sufficient burning and colorless flue dust, and the utility model can save energy by 40 percent corresponding to telescopic and hot pipe type air heaters.
Description
The utility model relates to a kind of indirect heat exchange hot-blast stove, particularly spiral heat exchange hot-blast stove.
At present, the hot-blast stove that China grain drier adopts mostly is telescopic, heat pipe-type, the shortcoming that these two kinds of hot-blast stoves exist that coal consumption is big, the thermal efficiency is low, volume is big, heat exchange area is little, exhaust gas temperature is high, dust concentration is big, the dead angle is many, dust stratification can't be eliminated in the stove.
The purpose of this utility model is the weak point that overcomes existing hot-blast stove, and a kind of spiral heat exchange hot-blast stove is provided.
The technical solution of the utility model is finished like this.
A kind of spiral heat exchange hot-blast stove, it is characterized in that: the spiral plate Heat Room is double-body bike with the combustion chamber and is connected, the side, fire grate below of combustion chamber is provided with the air inlet of combustion chamber, above the air inlet, side, fire grate top is provided with fire door, the fire grate top is the combustion chamber, roll over furnace wall and formed secondary combustion chamber, the secondary combustion chamber outlet is provided with smoke tube, flue gas connects the smoke chamber of spiral Heat Room by conduit, the spiral Heat Room constitutes two independently flue gas and hot blast helical ducts by the metal double helix plate, exhaust gases passes forms smoke chamber by the middle connecting duct of spiral Heat Room, and the smoke chamber gas flue is to inner rotary, and the end is provided with smokejack, adjacent with it helical duct is a hot-air channel, the centre of hot-air channel is the hot blast chamber, and hot-blast outlet is established in end, hot blast chamber, is provided with air inlet outside the spiral road and is connected with hot-air channel.Characteristics of the present utility model are that caloric value per hour reaches 500,000 kilocalories/h, consumption coal 80-100kg/h, hot blast output quantity 24000m
3/ h, hot blast temperature 180-240 ℃, exhaust gas temperature 180-200 ℃, sufficient combustion, flue dust are colourless.This utility model is than telescopic and Hot Blast Furnace With Heat Pipes energy-conservation 40%.
