Abstract
The utility model discloses an energy-saving hot air stove which is suitable for agriculture materials drying complete equipment. The utility model is provided with a coal adding machine 1, a furnace bottom base 3, a draught fan 6 and an aerator 10, etc. The utility model has the characterized in that the furnace top is designed as an arched roof heat exchanger 4, a triplet 11 is added between the furnace bottom base 3 and the aerator 15, and an ash separator 5 is also arranged at the front of the air heater fume outlet 13 and the draught fan 6. Owing to the arrangement of the furnace arch heat exchanger 4, the utility model not only makes full use of the waste hear of the furnace top, but also makes the hot air blow into the fire box and sufficient burning in order to get the purpose of saving energy. The arrangement of the triplet 11 can play the function of adjusting air heater fume flow exit temperature, and the arrangement of the ash separator 5 not only assure the materials quality but also purify the exhausted waste gas and is good for environmental protecting.
Description
The utility model relates to a kind of novel energy-conserving hot-blast stove, is mainly used in the agricultural material drying complete apparatus.
Ordinary hot wind furnace in the present agricultural material drying complete apparatus in the prior art, its furnace roof is built into refractory brick, its heat is lost in vain, can't be used, thereby the thermal efficiency is low, and the flue gas that the ordinary hot wind furnace comes out stream directly is used for dry agricultural material, thereby not only agricultural material is contaminated, and gives off the exhaust gases environmental protection, in addition, what ordinary hot wind furnace drum advanced burner hearth is cold wind, and unfavorable fire coal fully burns.
The purpose of this utility model will design a kind of fire coal that can make exactly and fully burn, and can make full use of the furnace roof waste heat, and can reduce the novel energy-conserving hot-blast stove of dry gas stream to agricultural material pollution and purifying exhaust air.
The purpose of this utility model is achieved in that the utility model removes parts such as comprising firing machine, coal bunker, furnace base, air-introduced machine, air blast, it is characterized in that furnace roof is designed to arch furnace roof heat exchanger, the furnace roof heat exchanger is made up of outer and internal layer and the some fin on internal layer; The utility model also adds a threeway between furnace base and air blast, the other end of threeway and hot-blast stove fume outlet are joined, and adorn two by-pass valve controls in threeway.After cold air enters the furnace roof heat exchanger, cold air is able to heat exchange betwixt, hot-air after the heating enters air blast and blows into burner hearth again, and just Ran Mei burning is more abundant, thereby has improved the thermal efficiency of hot-blast stove, when the flue gas stream temperature of coming out when hot-blast stove is too high, can close the valve that leads to air blast in the threeway, simultaneously, open the valve that leads to hot-blast stove fume flow export place in the threeway, can play the temperature of regulating hot-blast stove outlet flue gas stream, to guarantee to dry the quality of agricultural material.The utility model also adds deduster between hot-blast stove export pipeline and air-introduced machine, deduster can be according to the size of air quantity, carry out one or more configurations in parallel, because the setting of deduster, can purify Mars, cigarette ash and other granule foreign in the flue gas stream effectively, thereby alleviated greatly in the dry run the pollution of agricultural material, also alleviated the waste gas of discharging pollution simultaneously atmosphere.
The utility model compared with prior art its advantage is: 1. because the design of furnace roof heat exchanger, obtained heat exchange after can making cold air enter the furnace roof heat exchanger, heated air enters burner hearth, makes fired coal combustion abundant, thereby has reached energy-conservation purpose; 2. because the setting of threeway when heat exchanger flue gas stream temperature is too high, can be opened the valve that leads to the hot-blast stove exit in the threeway by closing the valve that leads to air blast in the threeway, can regulate the temperature of flue gas stream, thereby can guarantee dry mass; 3. Mars, cigarette ash and other granule foreigns are not only controlled in the setting of deduster effectively, guarantee the dries quantity to agricultural material, and the waste gas of Pai Chuing also is purified simultaneously, the favorable environment protection.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 looks generalized section for the master of novel energy-conserving hot-blast stove.
Fig. 2 is the top cross-sectional view of novel energy-conserving hot-blast stove.
Fig. 3 is the side-looking generalized section of novel energy-conserving hot-blast stove.
Below in conjunction with accompanying drawing 1---3 describe details and the working condition according to the concrete device that the utility model proposes in detail.
The utility model comprises firing machine 1, coal bunker 2, furnace base 3, air-introduced machine 6, mucking machine 12 and air blast 10 etc., furnace roof of the present utility model is designed to arch furnace roof heat exchanger 4, furnace roof heat exchanger 4 is internal layers 8 that the skin 7 made by metallic plate and metallic plate are made, and the some fin 9 on the internal layer 8 are formed.The utility model also adds a threeway 11 at furnace bottom 3 and 10 of air blasts, the other end of threeway 11 and hot-blast stove outlet 13 are joined, and in threeway 11, adorn two by-pass valve controls 14, after entering furnace roof heat exchanger 4, cold air is able to heat exchange betwixt, air after the heating enters air blast 10 and advances burner hearth once more, make burning of coal more abundant, thereby improved the fuel factor of hot-blast stove, when the flue gas stream temperature of coming out when hot-blast stove is higher, can close threeway 11 and lead to the valve 14 of air blast 10, open the valve 14 that leads to hot-blast stove outlet 13, can play the temperature of regulating hot-blast stove fume stream, so that the temperature when controlling dried material is better guaranteed dry mass.The utility model had also added deduster 5 before hot-blast stove fume flow export 13 and air-introduced machine 6, owing to set up deduster 5, can purify Mars, cigarette ash and other granule foreign in the oven dry flue gas effectively, thereby alleviated greatly in the drying course the pollution of material, also alleviated discharge useless simultaneously also to the pollution of air.
