Abstract
The utility model discloses a waste heat recovery device applicable to small heating equipment. The waste heat recovery device comprises a water tank, and a plurality of heat transferring coil pipes are arranged in the water tank. A flange of a smoke gas inlet connection pipe arranged on a side plate at the front end of the water tank is a hubbed flange, and the neck of the flange is in detachable connection with the smoke gas inlet connection pipe. The outer end of a smoke gas discharge outlet connection pipe arranged on a base plate of the water tank is connected with an discharge blower with adjustable pressure intensity. Because the hubbed flange is detachably connected with the smoke gas inlet connection pipe, using is flexible, and the hubbed flange can be matched correspondingly according to the smoke gas discharge caliber of the heating equipment. After exhaust gas emission of traditional small heating equipment is connected in a butt joint mode, high-temperature smoke gas discharged by a furnace flows through the heat transferring coil pipes and performs heat exchange with water in the water tank, the smoke gas is discharged after the temperature of the smoke gas falls to an emission standard, and the water in the water tank is heated continuously for utilizing. The exhaust blower with the adjustable pressure intensity is adopted in smoke gas emission for forced discharging, so that fuel is burned sufficiently, and therefore the combustion ratio of the fuel is improved. Compared with the prior art, the waste heat recovery device has obvious energy-saving benefits and great promotional value.
Description
Technical field
The utility model relates to a kind of waste-heat recovery device that is applicable to small-sized firing equipment.
Background technology
China's food and drink firing equipment and food processing, bamboo wood processing industry firing equipment energy consumption used is large, exhaust temperature is high, be generally 220 ℃---280 ℃, and the general small volume of this equipment, but longevity of service, the tail temperature is high, not only environment is caused to very big impact, and has caused great energy consumption waste.
The utility model content
The purpose of this utility model is to provide a kind of energy saver that reclaims small-sized firing equipment using waste heat from tail gas.
This waste-heat recovery device that is applicable to small-sized firing equipment that the utility model provides, this device comprises water tank, and some heat exchange coils are arranged in water tank; The front end of water tank has smoke inlet to take over, and there is hubbed flange dock with small-sized firing equipment the outer end that smoke inlet is taken over, between the neck of this flange and smoke inlet adapter for removably connecting.
On the top board of described water tank, be connected with automatic exhaust steam valve, side plate top, rear end and have that hot water outlet is taken over, have successively from front to back cooling water inlet to take over and blowdown discharge connection and fume emission discharge connection on base plate.
The flange face of described hubbed flange is useful on the oval hole of docking with small-sized firing equipment.
The entrance of described heat exchange coil is taken over and is communicated with described smoke inlet, and its outlet is communicated with described fume emission discharge connection.
The outer end of described fume emission discharge connection is connected with the adjustable exhaust blower of pressure.
Smoke inlet pipe connecting flange of the present utility model and smoke inlet be dismountable bascule between taking over, use flexible, can be according to the difference of firing equipment fume emission bore and corresponding coupling.The utility model is with after the exhaust emissions of conventional small firing equipment docks, the high-temperature flue gas of stove and accessory discharge is from flowing through heat exchange coil, with the water in water tank, carry out heat exchange, flue-gas temperature is discharged after being reduced to discharge standard, and the water in water tank is constantly supplied to utilize after heating.The adjustable exhaust blower forced-ventilated of pressure is adopted in the discharge of flue gas, so that the abundant burning of fuel improves fuel firing rate.Compared with prior art, have obvious energy-saving benefit, the utmost point has promotional value.
The accompanying drawing explanation
Fig. 1 is that the master of the utility model preferred embodiment looks cross-sectional schematic.
The specific embodiment
This waste-heat recovery device that is applicable to small-sized firing equipment that preferred embodiment, the utility model provide, support the use with the food and drink gas furnace of 100,000 kilocalories.As shown in Figure 1 and Figure 2, this device comprises water tank 1, and some heat exchange coils 2 are arranged in water tank 1.On the top board of water tank 1, be connected with on automatic exhaust steam valve 3, front end side plate have that smoke inlet takes over 4, side plate top, rear end has that hot water outlet takes over 5, have successively from front to back on base plate cooling water inlet to take over 6 and blowdown discharge connection 7 and fume emission discharge connection 8.There is the hubbed flange 9 docked with small-sized firing equipment the outer end of smoke inlet adapter 4, and the neck of this flange and smoke inlet are fastenedly connected with holding screw between taking over 4, and the flange face of this flange is the oval hole for the hole of docking with small-sized firing equipment.
The entrance of heat exchange coil 2 is taken over 4 with smoke inlet and is communicated with, and its outlet is communicated with fume emission discharge connection 8, and the outer end of fume emission discharge connection 8 is connected with the adjustable exhaust blower of pressure 10.
Through experiment, the food and drink gas furnace of the utility model and 100,000 kilocalories supports the use, and per hour can produce the hot water 400kg of 60 ℃-80 ℃, is equivalent to per hour reclaim heat energy 2.4 ten thousand kilocalories, presses natural gas 8500 kilocalories/m
3Calculate, be equivalent to energy-conservation 2.8 m
3/ h natural gas.
