Abstract
The invention provides a device for recycling waste heat generated in a procedure of acid making and conversion of sulphide ore, belonging to the field of recycling residual heat resources. The device for recycling the waste heat generated in the procedure of acid making and conversion of sulphide ore comprises a heat exchanger and an absorption tower, and is characterized in that a connecting heat pipe evaporator is arranged between the heat exchanger and the absorption tower, and the heat pipe evaporator is merged into a low-pressure steam through a steam manifold. The heat pipe evaporator comprises a flue gas channel (1), a heat pipe (2), water sleeves (3), an ascending pipe (4), a steam manifold (5) and a descending pipe (6), wherein the heat pipe (2) is arranged in the flue gas channel (1), the water sleeves (3) are respectively arranged on the upper end of the heat pipe (2), the water sleeve (3) is connected with the steam manifold (5) through the ascending pipe (4), the steam manifold (5) is connected with another water sleeve (3) through the descending pipe (6). The device has the advantages of small flow resistance, high heat transfer efficiency, compact device structure, light weight, and convenience for maintenance, and effectively prevents the boiler feed water from leaking in the fuel gas channel.
Description
Technical field
The present invention relates to a kind of sulphide ore relieving haperacidity conversion procedure heat recovery device, belong to residual heat resources and utilize the field again.
Background technology
Conversion procedure mainly is the dried SO of auto purification process in future
2Gas makes it change into SO through agent of touching of vanadium and oxygen effect
3, supply to do to inhale the post again and process sulfuric acid, traditional view thinks that the pyrite-based sulfuric acid production conversion procedure only need keep converter self thermal balance and get final product, therefore for many years a lot of pyrite-based sulfuric acid production enterprises do not recycle the conversion procedure heat of having more than needed always, but SO
3Flue gas dew point is lower, and traditional waste heat boiler is prone to dew point corrosion takes place, and causes steam to get into converter and absorption tower, causes catalyst efflorescence and chimney to smolder in a large number.Though pyrite-based sulfuric acid production conversion procedure heat recovery and utilization more than needed is set about by my company, conversion procedure is far away from boiler and feed pump, as increases an economizer and come the heating boiler water supply point to need that pipeline is grown, cost is big.
Summary of the invention
According to the deficiency of above prior art, the technical problem that the present invention will solve is: providing a kind of can be used for most of absorption of the heat of having more than needed to produce the conversion procedure heat recovery device that economizes on resources.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sulphide ore relieving haperacidity conversion procedure heat recovery device; Comprise a heat exchanger and a suction tower; It is characterized in that: heat exchanger and is inhaled between the tower connection heat pipe evaporator is set, and heat pipe evaporator is incorporated the low-pressure steam pipe network into through drum.Increase a heat pipe evaporator, utilize the water generates low-pressure steam in the heat pipe evaporator heating drum.
Described heat pipe evaporator comprises exhaust gases passes, heat pipe, water jacket, tedge, drum and down-comer; Exhaust gases passes inside is provided with heat pipe; Two heat pipes upper end is respectively arranged with water jacket, and water jacket connects drum through tedge, and drum connects another water jacket through down-comer.Heat pipe is positioned at SO
3In the flue, can not impact even heat pipe evaporator takes place by carbonated drink leakage, and water-steam system does not receive SO catalyst and production yet
3Sweep of gases.
The beneficial effect that the present invention had is: described heat recovery device flow resistance is little; Heat transfer efficiency is high, compact equipment, weight saving; And because every heat pipe is an independent component; Indivedual a small amount of heat pipes damage the heat exchange effect that does not influence entire equipment, and maintenance is convenient in simultaneously can be more convenient in maintenance, change.The cigarette G&W separates fully, has effectively avoided boiler feedwater to leak in the flue.Adjustment pitch of fin during design, thus to regulate the through-put power control heat pipe wall temperature of single heat pipe, prevent the corrosion of acid dew point.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of heat pipe evaporator.
Among the figure: 1, exhaust gases passes; 2, heat pipe; 3, water jacket; 4, tedge; 5, drum; 6, down-comer.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done and to be further described:
Shown in Fig. 1-2, a kind of sulphide ore relieving haperacidity conversion procedure heat recovery device comprises a heat exchanger and a suction tower, and heat exchanger and is inhaled between the tower connection heat pipe evaporator is set, and heat pipe evaporator is incorporated the low-pressure steam pipe network into through drum.Heat pipe evaporator comprises exhaust gases passes 1, heat pipe 2, water jacket 3, tedge 4, drum 5 and down-comer 6; Exhaust gases passes 1 inside is provided with heat pipe 2; Heat pipe 2 upper ends are respectively arranged with water jacket 3, and water jacket 3 connects drum 5 through tedge 4, and drum 5 connects another water jacket 3 through down-comer 6.
Operation principle and use:
During use, conversion procedure is the dried SO of auto purification process in the future
2Gas makes it change into SO through agent of touching of vanadium and oxygen effect
3, SO
3Through getting into heat pipe evaporator, SO behind the heat exchanger
3Heat in the flue gas is passed to the saturation water in the water jacket 3 by heat pipe 2, makes its vaporization, produces to such an extent that steam arrives drum 5 through tedge 4, goes into steam pipe system through shunting rear push, and the water in the drum is supplied with by feed pump.Heat pipe is constantly imported water jacket with heat, accomplishes basic carbonated drink circulation through outside steam-water pipe and tedge 4, down-comer 6, reaches SO
3Flue-gas temperature reduces and is converted into the purpose of steam, gets into one at last and inhales tower.
