Abstract
The utility model relates to a coalgas energy-saving recovery device belonging to field of combustion equipment. The coalgas energy-saving recovery device comprises a first coalgas flue, a coalgas exchanger, a second coalgas flue, and a chimney. The joint between the second coalgas flue and the chimney is provided with a chimney inlet gate plate; the second coalgas flue is sequentially connected with a first water sealing device, an induced fan, a second water sealing device, a coalgas storage tank, and a third water sealing device through a pipeline at front of the chimney inlet gate plate; the outlet of the third water sealing device is connected with the inlet of the first coalgas flue; and the second water sealing device is provided with an absorbing coalgas valve. The benefits are as follows: the device is environmental-friendly, energy-saving, has significant emission reduction effect, recycles lost coalgas at each reversal interval for re-combustion in furnace, saves coal by hundreds of thousands of tons or more, reduces emission, is beneficial for the nation and the people, and has good popularizing prospect.
Description
(1) technical field
The utility model belongs to the combustion equipment field, particularly a kind of gas energy-saving recovery device.
(2) background technology
Kiln was the full coal gas of 28m2 between one of our company's operation was spread, triple channel heat accumulating type coal gas horse shoe flame cell furnace, owing to be once every commutation in 30 minutes, each direction exchanging gas and airspace 6-10 second, cause a part during this time every in coal gas from smoke stack emission to atmosphere, waste, again contaminate environment.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of environmental protection, energy-conservation, the gas energy-saving recovery device that reduces discharging remarkable benefit are provided.
The utility model is achieved by the following technical solution:
Gas energy-saving recovery device of the present utility model, comprise first coal gas flue, coal gas exchanger, second coal gas flue, the chimney that connect successively, its special character is: chimney inlet flashboard is set in the junction of second coal gas flue and chimney, second coal gas flue connected first water seal arrangement, induced draft fan, second water seal arrangement, gas holder, the 3rd water seal arrangement successively by pipeline before being positioned at chimney inlet flashboard, the outlet of the 3rd water seal arrangement connects first coal gas flue inlet, and second water seal arrangement is provided with the suction gas valve.
Gas energy-saving recovery device of the present utility model, the gas holder bottom is provided with the 4th water seal arrangement.
The beneficial effects of the utility model are that environmental protection, energy-conservation, reduction of discharging remarkable benefit come to go into again the stove burning with the coal-gas recovering that runs off in each reversal interval.According to China's energy scenario, existing coal gas horse shoe flame glass melter is widely applied, and economizes on coal 4.86 tons for every square metre by this device, and year economizes on coal more than few hundred thousand tonnes of, and reduces discharging again, benefits the nation and the people, and popularizing application prospect is good.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure, 1 second coal gas flue, 2 chimneys, 3 chimneys inlet flashboard, 4 first water seal arrangements, 5 induced draft fans, 6 second water seal arrangements, 7 gas holders, 8 the 3rd water seal arrangements, 9 suck gas valve, 10 the 4th water seal arrangements, 11 first coal gas flues, 12 coal gas exchanger.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Gas energy-saving recovery device of the present utility model, comprise first coal gas flue 11 that connects successively, coal gas exchanger 12, second coal gas flue 1, chimney 2, chimney inlet flashboard 3 is set between second coal gas flue 1 and chimney 2, second coal gas flue connected first water seal arrangement 4 successively by pipeline before being positioned at chimney inlet flashboard, induced draft fan 5, second water seal arrangement 6, gas holder 7, the 3rd water seal arrangement 8, the outlet of the 3rd water seal arrangement connects first coal gas flue, 11 inlets, second water seal arrangement 6 is provided with and sucks gas valve 9, and the gas holder bottom is provided with the 4th water seal arrangement 10.Gas line and chimney inlet valve plate dimension of opening are between 200X200mm to 2000X2000mm.
The principle of gas recovering device: 3-5 second before commutation coal gas valve plate on the coal gas flue is fallen, stop coal gas (during commutation) from then on to flow into chimney.Open to suck the coal gas flue valve simultaneously, induced draft fan slowly starts this moment, treat reversing valve (coal gas exchanger) after, coal gas enters gas flue, though pipeline and gallery pressure deflection do not influence burning, induced draft fan operation 2-3 minute, mention flashboard, stop fan operation, this time end of run.
Practical application effect:
At first, save energy, coal conservation of every commutation is about 7.88kg, and a day coal conservation is 378kg, and a month coal conservation is 11.34 tons, and a year coal conservation is 136.17 tons.
Next: in commutation process, do not go up 30-50 ℃ of recovery gas fitting reduction, help the stable of melting technology, the benefit bigger founding of glass because recovery coal gas is gone into the temperature fluctuation of stove melting pool.
Amount of energy saving calculates:
A coal gas amount (recovery) is calculated
In the coal gas flue: 14.5m

Every day coal conservation: 378kg
Every month coal conservation: 11.347 tons
Annual coal conservation: 136.17 tons
By advancing company's coal price now be: 900 yuan of/ton calculating
The benefit of economizing on coal in year is: 122553 yuan/year
Every day power consumption: artificial, equipment amortization is 22553 yuan/year
Year actual benefit is: 100,000 yuan
Annual power consumption expense, labour cost, depreciation of equipment are 22553 yuan/year
Year actual benefit is: 100,000 yuan.
