Abstract
The utility model discloses a submerged combustion type water jacket furnace comprising a water jacket furnace casing, wherein the upper part of the water jacket furnace casing is provided with a submerged combustor and a chimney, the bottom of the submerged combustor is provided with a smoke collection box, and the submerged combustor and the smoke collection box are respectively arranged in water; a heat exchange coil tube is arranged in the water jacket furnace casing, and the lower end and the upper end of the heat exchange coil tube are respectively connected with a material inlet and a material outlet; and the heat exchange coil tube is made of a heat exchange tube bundle formed by directly bending a seamless steel tube. The submerged combustion type water jacket furnace has the advantages of good heat exchange effect, high heat efficiency, great reduction of fuel gas of the water jacket furnace, low temperature (below 100 DEG C)of discharged smoke, convenient discharge and good environmental protection; the submerged combustion type water jacket furnace dispenses with the structures of fire tubes and discharge flues, reduces the volume of the furnace casing, does not adopt metal heat-transfer surfaces and avoids accidents caused by the damage of the heat-transfer fire tubes, and as the heat exchange tube bundle is formed by directly bending the seamless steel tube, the production difficulty, the production cost and the fluid resistance are reduced and the heat efficiency is increased.
Description
Technical field
The utility model relates to a kind of burning heater, especially relates to the water jacket furnace that a kind of water is cooked heat transfer medium heating natural gas.
Background technology
From the gas pressure height of underground mining, carry for ease of ground, need the throttling step-down.But throttling step-down process must cause the gas medium temperature and descend, and when temperature drops to water dew point when following, the impurity such as some hydrates in the natural gas will freeze, and it is stifled to form ice in conveyance conduit, causes pipeline breaking.Take place for anti-stagnant ice is stifled, so in advance will be with water jacket furnace to the natural gas heat temperature raising.Water jacket furnace realizes that to the heat temperature raising mode that adds hot water commonly used of natural gas the existing mode that adds hot water is the fire-tube type heating.The structure of fire-tube type water jacket furnace as shown in Figure 1, comprise housing 1, water 2, heat exchanger tube 3, material outlet 4, high pressure elbow 5, material inlet 6, smokejack 7, fire tube 8, long flame 9, air intlet 10, burner 11, fuel gas import 12, chimney 13, oxygen analyzer 14.The burner 1 that is installed in water jacket furnace housing 1 below has air intlet 10 and fuel gas import 12, and the heat that long flame 9 produces is passed to water 2 by fire tube 8; High-temperature flue gas is discharged from the chimney 13 that has oxygen analyzer 14 after smokejack 7 and water 2 further heat exchange, and exhaust gas temperature is not less than 250 ° of C; The natural gas cold fluid flows into from material inlet 6, flows through the high pressure heat-exchanging tube bundle, be heated after water 2 carry out heat exchange after, flow out from material outlet 4, enter the process unit of appointment.
The fire-tube type water jacket furnace mainly utilizes the mode and the water 2 of partition heating to carry out heat exchange by fire tube 8, and secondly also by smokejack 7 and water heat exchange, the heat exchange effect is limited, causes exhaust gas temperature up to 250 ℃, and heat loss is big; And fire tube 8 is subjected to hyperthermia radiation for a long time, and is fragile; Simultaneously, because the water jacket furnace housing bottom is laid with chimney, fire tube and smokejack, remaining space is narrow and small, and the high pressure heat-exchanging tube bundle is can only be by bending radius little and make the big high pressure elbow 5 of assembling difficulty and be connected with heat exchange coil 3; Moreover, fire tube 8 is arranged in the water jacket furnace housing, structures such as flue 7 cause heat-exchanging tube bundle comb difficulty, and the apparatus casing volume enlarges markedly, the cost height.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of submerged combustion water jacket furnace is provided, and has cancelled the heat transfer fire tube, and with high-temperature flue gas and the direct bubbling heat exchange of water, exhaust gas temperature is controlled at below 100 ℃, good effect of heat exchange, thermal efficiency height.
The technical solution of the utility model is: a kind of submerged combustion water jacket furnace, comprise the water jacket furnace housing, and on water jacket furnace housing top submerged burner and chimney are set, described submerged burner bottom is provided with the collection cigarette case, and submerged burner and collection cigarette case all immerse in the water; Arrange heat exchange coil at the water jacket furnace housing bottom, the lower end of heat exchange coil is connected material inlet and material outlet respectively with the upper end, and described heat exchange coil directly adopts seamless steel pipe to bend by heat-exchanging tube bundle and forms; Bottom at described water jacket furnace housing is provided with agitator.
On described inner wall of stack, oxygen analyzer is set.
Compared with prior art, the utility model has the advantages that: adopt the collection cigarette case to be immersed in the water, make high-temperature flue gas and water directly carry out the bubbling heat exchange, and accelerate water and circulate and strengthen the heat exchange effect by agitator is set, thermal efficiency height reduces the fuel gas consumption of water jacket furnace greatly, and exhaust gas temperature is lower than 100 ℃, be convenient to discharging, the feature of environmental protection is good; Cancel structures such as fire tube and smokejack, reduced the apparatus casing volume; Simultaneously, do not have the metal heat transfer face, avoided the heat transfer fire tube to be destroyed and accidents caused owing to cancelled conducting heat and use fire tube; And because the laying of water jacket furnace housing bottom cancellation fire tube and smokejack, reserve enough spaces and arranged heat exchange coil, making heat-exchanging tube bundle directly to adopt seamless steel pipe to bend forms, this connected mode has not only reduced manufacture difficulty and manufacturing cost, and can also reduce fluid resistance, improve the thermal efficiency.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of existing fire-tube type water jacket furnace;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
A kind of submerged combustion water jacket furnace as shown in Figure 2, comprises submerged burner 21, air intlet 22, fuel gas import 23, chimney 24, oxygen analysis 25, water 26, collection cigarette case 27, material outlet 28, material inlet 29, heat exchange coil 30, water jacket furnace housing 31 and agitator 32.
In order easily the discharging flue gas to be carried out check and analysis, can on chimney 24 inwalls, oxygen analyzer 25 be set.
In order to accelerate the water circulation, strengthen the heat exchange effect, agitator 32 can also be set in the bottom of water jacket furnace housing 31.
Operation principle of the present utility model is: the collection cigarette case 27 of high-temperature flue gas from be immersed in water 26 that submerged burner 21 burning produces overflows, high-temperature flue gas directly with the water heat exchange after, become low-temperature flue gas, from chimney 24 discharges; The natural gas cold fluid flows into from material inlet 29, carries out heat exchange by heat exchange coil 30 and heated water 26, and the natural gas fluid after the heating flows out from material outlet 28 and enters the process unit of appointment.
