The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, water jacket furnace, comprise horizontal type shell 1, described housing 1 is outside equipped with burner 2 and chimney 3, burner 2 and chimney 3 are positioned at the homonymy of housing 1, housing 1 inner chamber bottom is provided with fire cylinder, fire cylinder is formed by connecting by combustion chamber 4 and smoke pipe tube bank 5, the other end of combustion chamber 4 stretches out housing 1 and is connected with burner 2, the other end of smoke pipe tube bank 5 is connected with chimney 3, housing 1 inner chamber top is provided for passing into the snakelike tube bank 6 of crude oil or natural gas, outlet header 7 and import header 8, one end of snakelike tube bank 6 is connected with import header 7 respectively---shown in Fig. 5, the other end is connected 8 with outlet header respectively, the port of export of the entrance point of import header 8 and outlet header 7 all stretches out housing 1 and is positioned at the homonymy of housing 1.As shown in Figure 2, wherein, described snakelike tube bank 6 is formed by least two S-shaped bendings of heat exchanger tube dish 9 and heat exchanger tube dish 9 coming in housing 1.In order further to improve heat exchange efficiency, the ratio of described heat exchanger tube dish longitudinal pitch A and transverse pitch B is 0.5～3.As shown in Figure 3, or described snakelike tube bank 6 is formed by least two S-shaped bendings of heat exchanger tube dish 9 and heat exchanger tube dish 9 dislocation is arranged in housing.
As shown in Figure 4, in order to improve the heat exchange efficiency of the medium in flue gas and housing, the length of described smoke pipe tube bank 5 accounts for 0.1～0.5 of fire cylinder assembly.
For the security to water jacket furnace, monitoring, maintenance and fixing, on described housing 1, be provided with safety valve 10, liquid level gauge 11, manhole 12 and saddle 13.
The operation principle of the utility model water jacket furnace is: fuel and air together spray into the interior burning in combustion chamber 4 through burner 2, the high-temperature flue gas of burning heat release and generation transfers heat to combustion chamber 4 with the form of radiation and convection current and smoke pipe is restrained 5 walls, wall is delivered to heat in the heat transfer medium (demineralized water) in housing 1 again, and heated heat transfer medium transfers heat to snakelike tube bank 6 again with the form of convection current.Natural gas or crude oil enter the rear dispersion of import header 7 by main pipeline and enter the heat exchanger tube dish 9 being arranged side by side, then with heat exchanger tube dish 9 outside heat transfer medium carry out heat exchange, the crude oil after heated or natural gas import outlet header 8 and also flow into follow-up pipeline.Owing to having increased the flow of heat exchange area and natural gas, crude oil, thereby improve heat exchange power, and dwindled snakelike tube bank 6 in the interior shared space of housing 1, reduced production cost, improved production efficiency.
