Abstract
The utility model relates to a water jacket heating furnace with pin tubes. In the utility model, pin tubes are used as elements of the heat transfer surface of a smoke tube and elements of the heat exchanging surface of a tube side, and the autologous characteristic structural style of the pin tubes enlarges the heat transfer surface of the smoke tube and the heat exchanging surface of the tube side; one end of a shell of a water jacket furnace is provided with a combustion engine and an outer flue pipe of the water jacket furnace, the lower part of the inner of the shell is a fire cylinder of the water jacket furnace, and a plurality of heat exchanging elements of the pin tubes are arranged in the fire cylinder of the water jacket furnace; the upper part of the inner of the shell is provided with the pin tube side of the water jacket furnace, and water heat transfer medium of the water jacket furnace, so the improvement of the integral heat exchanging efficiency of the water jacket furnace is realized, and defects existing in the prior art are overcome. Compared with the existing water jacket heat furnace of the same standard, the utility model has the advantages of small volume and high thermal efficiency.
Description
The utility model relates to a kind of pin-fin tube water batch heater, belongs to high efficient heat exchanging technology application apparatus, the particularly application in the water batch heater of oil field oil extraction transportation pumping plant heating system.
Existing water batch heater is divided into heating part and heated portion.Yet no matter be its heating part, or heated portion, the heat exchange element that imports medium is light pipe, so heat-transfer area, tube side heat-transfer surface in the stove are restricted, has also just determined the heat exchange efficiency of stove integral body.Current water batch heater in usefulness belongs to this structure basically, and heat exchange efficiency is lower, and energy waste is bigger.
The purpose of this utility model is: a kind of pin-fin tube water batch heater is provided, with the element of pin-fin tube as smoke pipe heat-transfer area and tube side heat-transfer surface, increase smoke pipe heat-transfer area and tube side heat-transfer surface with pin-fin tube self its specific structure form, thereby realize improving the whole heat exchange efficiency of water jacket furnace, overcome the defective that exists in the prior art, reduce energy waste.

Fig. 2. the A-A cutaway view of Fig. 1
Fig. 3. fiery barrel structure schematic diagram
Fig. 4. the pin-fin tube structural representation
Below in conjunction with accompanying drawing the utility model is described in detail. Such as Fig. 1, an end of water jacket furnace shell 6 Be provided with the outer chimney 7 of burning machine 1 and water jacket stove; The bottom is water jacket stove fire tube 2 in the housing. The water jacket stove Be provided with some pin-fin tube heat exchange elements 3 in the fire tube 2. The housing internal upper part is provided with water jacket stove pin-fin tube journey 4, water jacket stove heat transfer water medium 5. Water jacket stove pin-fin tube journey 4 is pin-fin tube, is horizontally disposed with. Pin Nail pipe heat exchange element 3 in water jacket stove fire tube 2 with vertical setting of water jacket stove fire tube 2 axis, and 15-45 degree angle is staggered each other between every, totally is the M shape setting. Such as Fig. 2, be Fig. 1 The A-A cutaway view, showed the structure of the horizontal direction of water jacket stove fire tube 2. Water jacket stove fire tube 2 for the U-shaped dish crouches in water jacket furnace shell 6, and pin-fin tube heat exchange element 3 is arranged on water jacket stove fire tube Among 2. Such as Fig. 3, the cross section is water jacket stove fire tube 2 among the figure, and vertical nail pipe is that pin-fin tube changes Thermal element 3. Such as Fig. 4, be pin-fin tube structure schematic diagram, the Guan Tiwei seamless steel pipe 10 of pin-fin tube, Outer wall at seamless steel pipe 10 is connected with some vertically uniform pins 11.
Embodiment: pin-fin tube is set in water jacket furnace replaces original light pipe, aciculiform pin base the earth has been expanded heating surface and heat-transfer surface.The one, pin-fin tube heat exchange element 3 is installed in the centre position of fire tube, thereby forms a plurality of convection loop that are subjected to hot water to penetrate fire tube center, the heat at fire tube center is absorbed rapidly import in the stove.Another is a water jacket furnace pin tube side 4, and in fact it is a kind of heat pipe, and its function is exactly for heat exchange.Under the configuration state of pin-fin tube, also realized greatly expanding the purpose of heat-transfer surface.After the heating surface area and heat exchange area in the expansion water jacket furnace, the thermal efficiency of water jacket furnace is significantly improved.
Advantage of the present utility model: 1. water jacket heating furnace of the present utility model with the existing water of standard The cover heating furnace is compared, and has the advantage that volume is little, the thermal efficiency is high. New product save material, Energy savings has great economic benefit. 3. rational in infrastructure, safe and reliable to operation.
