Background technology
Verticle gas hot-water boiler take natural gas as the important thermal power transfer equipment of fuel, and it is simple and compact for structure, floor space is little, environmental pollution is low, is thus widely used.In current engineering reality, vertical gas boiler mostly is fire tube list return structures, and smoke pipe generally adopts smooth pipe, be subject to the restriction of boiler volume, traditional vertical gas fired-boiler also exists that flue gas flow is shorter, boiler heat exchange area is less, the problems such as lateral fluid convection transfer rate is lower in smoke pipe, the heat that fuel combustion is discharged cannot be fully absorbed, thus causes that exhaust gas temperature is higher, boiler thermal output is on the low side.According to statistics, traditional vertical gas fired-boiler exhaust gas temperature, generally more than 200 DEG C, not only causes a large amount of energy wastes, and causes thermal pollution to environment.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide that a kind of novel structure, heat transfer efficiency are higher, the simple vertical double back journey gas-fired water heating boiler of manufacturing process.
The present invention adopts following technical scheme: a kind of vertical double back journey gas-fired water heating boiler, comprise base, furnace bottom circle, flue, burner, flame-observing mirror, middle smoke box, upper smoke tube, cylindrical shell, outlet pipe, collection smoke box, smoke exhaust pipe, lower smoke tube and water inlet pipe, it is characterized in that, smoke box in the middle of arranging one above described cylindrical shell inner furnace, upper smoke tube and lower smoke tube are all connected with middle smoke box, the upper end of upper smoke tube is connected with collection smoke box, and lower smoke tube is positioned at around flue, and its lower end is connected with flue bottom; Burner is installed on the top of flue, and in flue, the sidewall of positive corresponding flame installs arc refractory material additional, and the thermal-flame of flue internal upper part and the revolution of flue gas lower portion, as flue gas first backhaul; The flue gas that flue bottom is discharged enters upper smoke tube from lower smoke tube through middle smoke box, as flue gas second backhaul; Flue, smoke pipe and middle smoke box are all the heat-transfer surfaces of flue gas and stove water.
Described middle smoke box is cylinder, and its external diameter is less than cylinder internal diameter and is about 40mm, and its upper surface and lower surface respectively as the tube sheet of upper smoke tube and lower smoke tube, and connect upper smoke tube and lower smoke tube respectively.
All install the outer blind pipe around flight additional in described upper smoke tube and lower smoke tube, blind pipe external diameter is about 22mm, occupies the segment fluid flow space of smoke pipe central area, and the outer rim of flight is close to smoke pipe inwall, and flight pitch is about 126mm.
The straight length of described upper smoke tube and lower smoke tube all welds straight longitudinal fin outward, and the quantity of the outer straight longitudinal fin of single flue is about 24, and fin height is 9 ~ 15mm.
Described lower smoke tube is evenly distributed on around flue, and its lower ends bent is in 90 ° and be welded in the bottom of flue.
After the present invention adopts technique scheme, compared with prior art there is following beneficial effect: one is that vertical double back journey gas fired-boiler adopts upper smoke tube, middle smoke box and lower smoke tube connected structure, as flue gas second backhaul, significantly increase the heat exchange area of flue gas and stove water, extend flue gas flow; Two is the top that burner is installed on flue, makes thermal-flame and flue gas in flue from the revolution of top lower portion, as flue gas first backhaul, add the time of staying of flue gas in flue, improve the radiation heat transfer efficiency between flue gas and flue; Three is all install the outer blind pipe around flight in upper smoke tube and lower smoke tube additional, occupy the segment fluid flow space of smoke pipe central area, the circulation area of flue gas is reduced, and flight changes velocity attitude, improve flue gas flow rate, thus enhance the heat convection of flue gas and tube wall; Four is that the straight length of upper smoke tube and lower smoke tube all welds straight longitudinal fin outward, significantly increases the heat exchange area outside smoke pipe, thus enhances the heat convection of stove water and smoke pipe; Five is application of above-mentioned various augmentation of heat transfer structure, effectively can improve the heat exchange efficiency of vertical boiler entirety, thus can reduce quantity and the boiler volume of smoke pipe, thus reduces material consumption and save manufacturing cost.
