Abstract
The utility model relates to the field of boiler flue gas waste heat recovery air pre-heaters, in particular to a heat pipe type boiler air pre-heater. An air circulation part and a flue gas circulation part are connected through a heat pipe, the heat pipe is fixed with a separation board through full-length welding, an air inlet is arranged on one side of the air circulation part, an air outlet is arranged on the other side of the air circulation part, a flue gas outlet is arranged on one side of the gas flue circulation part, a flue gas inlet is arranged on the other side of the gas flue circulation part, an ash removal door is arranged on the outer side wall of the flue gas circulation part, an ash discharging hopper is arranged below the bottom of the gas flue circulation part, and stand columns are arranged on two sides of the ash discharging hopper. The heat pipe type boiler air pre-heater is small in size, high in heat exchange efficiency, small in resistance and easy and convenient to install; the ash removal door and the ash discharging hopper are arranged, ash is removed through an automatic ash removing function of the heat pipe, ash removal difficulty is greatly reduced for operators, and the service life of the product is prolonged; and reverse operation of flue gas and air is achieved, heat exchange is promoted through temperature difference enlargement, and therefore the optimum energy-saving effect can be achieved.
Description
Technical field:
The utility model relates to residual heat from boiler fume and reclaims the air preheater field, is specifically related to a kind of tubular boiler air preheater.
Background technology:
Existing boiler adopts tubular air preheater more, and the main heat transfer component of tubular air preheater is a thin-wall steel tube.Tubular air preheater is cube more, and steel pipe is vertically staggered each other, and two ends are welded on the lower perforated plate.Tubular air preheater is equipped with sagging plate in bobbin carriage, flue gas up and down by preheater, then laterally by preheater, is finished the heat conduction along steel pipe.The shortcoming of tubular air preheater is that volume is big, stifled easily ash in the steel pipe, be not easy to cleaning and wear and tear easily in the gas approach place.
The utility model content:
The purpose of this utility model provides a kind of tubular boiler air preheater, its volume is little, the heat exchange efficiency height, resistance is little, installation is simple and convenient, be provided with shoot door and ash dropping hopper, utilize the automatic ash removing function of heat pipe to carry out deashing, significantly reduce operative employee's deashing difficulty, increased the long service life of product, with flue gas and air antikinesis, by enlarging the temperature difference, promote heat exchange, so that reach optimum energy-saving effect.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises the circulation of air part A, flue gas circulation part B, column 1, shoot door 2, exhanst gas outlet 3, gas approach 4, dividing plate 5, heat pipe 6, air intlet 7, air outlet slit 8 and ash dropping hopper 9, the circulation of air part A is connected by heat pipe 6 with flue gas circulation part B, heat pipe 6 and dividing plate 5 are fixed by full weld, one side of circulation of air part A is provided with air intlet 7, opposite side is provided with air outlet slit 8, the side of flue gas circulation part B is provided with exhanst gas outlet 3, opposite side is provided with gas approach 4, flue gas circulation part B lateral wall is provided with shoot door 2, below, flue gas circulation part B bottom is provided with ash dropping hopper 9, and the both sides of ash dropping hopper 9 are provided with column 1.
Two parts up and down of described heat pipe 6 all have fin 6-1, increase heat exchange area, improve heat exchange efficiency.
The equipment end portion was connected with boiler flue when the utility model was installed, flue gas enters to wash away after heat pipe 6 heat releases via gas approach 4 and is discharged by exhanst gas outlet 3, the equipment upper part then is connected with the air blast air channel, air blast is entered by air intlet 7, blast boiler furnace by air outlet slit 8 discharges again after washing away heat pipe 6 heat absorptions, improve boiler and mend the wind-warm syndrome degree.
The utlity model has following beneficial effect: its volume is little, the heat exchange efficiency height, resistance is little, installation is simple and convenient, be provided with shoot door and ash dropping hopper, utilize the automatic ash removing function of heat pipe to carry out deashing, significantly reduce operative employee's deashing difficulty, increased the long service life of product, with flue gas and air antikinesis, by enlarging the temperature difference, promote heat exchange, so that reach optimum energy-saving effect.
