Board-like combination condensation Hot water units
Technical field
This utility model relates to a kind of board-like combination condensation Hot water units, is mainly made up of cigarette-water heat exchanger and premixed metal burner, and cigarette-water heat exchanger is to adopt some heat exchange plate superpositions to be welded。Premixed metal burner is made up of burner and tube type metal combustion front, and fuel adopts gas cleaning fuel。Owing to cigarette-water heat exchanger employs heat exchange plate structure, it is greatly improved the thermal efficiency of unit, reduces the weight and volume of unit。After additionally burner adopts premixed metal burner, combustion intensity can be improved, the generation of nitrogen oxides can be reduced again。The purposes of board-like combination condensation Hot water units is the same with the purposes of traditional gas normal-pressure Hot water units, gas normal-pressure hot-water boiler, mainly produces normal pressure, room temperature hot water, for the heating of building, life and industrial manufacture process hot water etc.。
Background technology
At present, traditional gas and hot water unit and gas-fired water heating boiler all by burner, combustor, add hot cell three major part and form。Burner is to light after fuel and air being mixed to produce high-temperature flue gas after burning Indoor Combustion, fuel and air burning。High-temperature flue gas enters and adds hot cell, the water in the heat transfer pipe that heating heating is indoor, makes the temperature that the temperature of water improves flue gas reduce。What the height of the thermal efficiency depended primarily on the structure and heating surface area that add hot cell, conventional hot water's unit and conventional hot water's boiler adds hot cell, mostly adopts tubular type heating arrangement, owing to the heat transfer coefficient of tubular type heating arrangement is low, and high fume temperature。Do not have water vapour condensation in flue gas, so the thermal efficiency is low。This board-like combination condensation Hot water units changes the heated structure adding hot cell, changes original tubular type heating arrangement into plate-sheet-type heat exchange structure, and heat exchange plate is on one piece of metallic plate, strikes out combuster, adds hot cell, the heat exchange plate of discharge flue structure。Then some heat exchange plate Combination Welding are become cigarette-water heat exchanger that a heat transfer coefficient is high。Coordinate with premixed metal burner again, form a novel Hot water units and be called board-like combination condensation Hot water units。Owing to have employed plate-sheet-type heat exchange structure, unit has the feature that volume is little, lightweight, the thermal efficiency is high, hazardous emission is low after making。
Summary of the invention
The purpose of this utility model is to provide one, and some heat exchange plate Combination Welding are become cigarette-water heat exchanger that a heat transfer coefficient is high。Coordinate with premixed metal burner again, form a novel Hot water units and be called board-like combination condensation Hot water units。
The purpose of this utility model is achieved in that board-like combination condensation Hot water units is mainly made up of cigarette-water heat exchanger and premixed metal burner。Cigarette-water heat exchanger be by some be stamped with combustor, add hot cell, cigarette channel superposes with the heat exchange plate of aquaporin structure and to be welded, the top of heat exchange plate is that combustor becomes circular structure, the middle part of heat exchange plate is cigarette channel and aquaporin, and left aquaporin and crossed cigarette channel, the bottom of heat exchange plate becomes circular structure for smoke evacuation room。The one side of heat exchange plate is cigarette side was cigarette channel, the top crossing cigarette channel communicates with combustor, and the bottom crossing cigarette channel communicates with smoke evacuation room, the high-temperature flue gas produced in combustor by cigarette side cigarette channel, entering smoke evacuation room, the reverse side of heat exchange plate cigarette side is water side was aquaporin。Cigarette-water heat exchanger is to be welded by some heat exchange plate superpositions, and the top of the cigarette-water heat exchanger after shaping is the combustor of a garden tubular, and bottom is a garden tubular smoke evacuation room parallel with combustor, and combustor is connected by cigarette channel with smoke evacuation room。After fuel gas buring in combustor, the high-temperature flue gas produced enters smoke evacuation room through cigarette channel, in cigarette channel excessively, the heat of high-temperature flue gas is through heat exchange plate, it was conducted to the water at low temperature crossed in aquaporin of cigarette channel reverse side, the temperature making water improves, the temperature of cigarette decreases, and reduces the flue gas after temperature and enters smoke evacuation room, discharges outside cigarette-water heat exchanger then through exhaust opening。Cigarette-water heat exchanger periphery is the barrel-like structure being welded into metallic plate, is enclosed in wherein by cigarette-water heat exchanger, and bottom is water at low temperature collecting channel, and side is provided with water inlet, and top is high-temperature water collecting channel, and side is provided with outlet。Heated water at low temperature is entered water at low temperature collecting channel by water inlet, and water at low temperature rises along the aquaporin of heat exchange plate, carries out heat exchange with heat exchange plate cigarette side high-temperature flue gas, makes the temperature of water improve。The water of rising temperature is sent for user by outlet after concentrating in high-temperature water collecting channel。Premixed metal burner is made up of burner and tube type metal combustion front, after combustion gas and air are pre-mixed by burner, send into tube type metal combustion front ignition, combustion gas forms uniform combustion front in the burning of tube type metal combustion front, adopt premixed metal burner, not only can improve combustion intensity, the generation of nitrogen oxides can be reduced again, board-like combination condensation Hot water units all devices is arranged on base, the unit casing that the periphery metal material of equipment is made。
Owing to have employed such scheme, so that it may with cigarette-water heat exchanger and premixed metal burner, be welded into board-like combination condensation Hot water units。

Detailed description of the invention
In the drawings, some heat exchange plates 1 superposition it is welded into cigarette-water heat exchanger 2。Cigarette-water heat exchanger top is the combustor 3 of a garden tubular, and bottom is a garden tubular smoke evacuation room 4 parallel with combustor 3, and combustor 3 is communicated by cigarette channel 5 with smoke evacuation room 4。Burner 6 is connected with tube type metal combustion front 7, forms premixed metal burner 8。Tube type metal combustion front 7 is located at the centre of combustor 2。Burner sends into tube type metal combustion front, ignition on tube type metal combustion front after combustion gas and air are done premix, produce high-temperature flue gas。High-temperature flue gas is entered smoke evacuation room 4 by combustor 3 through cigarette channel 5, and high-temperature flue gas transfers heat to the water of back side aquaporin 9 when by cigarette channel 5, makes the temperature of water improve, and the temperature of flue gas declines。Water inlet 10 and water at low temperature collecting channel 11 are connected, and enter high-temperature water collecting channel 12 through aquaporin 9。High-temperature water collecting channel 12 connects with outlet 13, and heated water is sent unit for user。Smoke evacuation room 4 connects with exhaust opening 14, will be lowered temperature flue gas and discharge unit。All of equipment is arranged on base 14, the shell 15 that peripheral installation metal material is made, and forms board-like combination condensation Hot water units。
