Abstract

A finned diaphragm wall condensation type vacuum boiler belongs to a boiler product. The technical scheme of the utility model is as follows: the utility model comprises a boiler body, a heat exchanger and a condenser, wherein the boiler body comprises a hearth formed by fins and pipes, a front smoke box rotary combustor and a vacuum hearth, hot medium water is arranged in the boiler body, the upper half of the vacuum hearth is provided with a heat exchange tube, the heat exchanger comprises a heat exchange tube, a container, a water inlet and a water outlet, the right part of the hearth is provided with the condenser, a finned tube group of which finned tubes are connected together in series are arranged in the condenser, the water inlet of the finned tube group is connected with a return pipe of the boiler, and the water outlet of the finned tube group is connected with the water inlet of the heat exchanger through pipes. The utility model has the advantages that the hearth formed by fins and pipes has large heating surface, the water capacity is small, the boiler can be started fast; the temperature of the front smoke box is low, the service life is long; and the temperature of the condenser is reduced, and the heat recovery efficiency is higher, thus reaching the aim of energy-saving and environmental protection.

Description

A kind of fin membranous wall condensing vacuum boiler
One, technical field: the utility model belongs to boiler product.
Two, technical background
Owing to contain protium in the natural gas, can produce about 1.55kg/m during burning 3Steam, its latent heat of vaporization is about 3600KJ/kg, accounts for about 10% of natural gas low heat valve.When exhaust gas temperature was higher, steam can not be condensed, and fell with fume emission, formed flue gas loss.The vacuum boiler that has the condensation function of recovering waste heat at present is provided with the smoke evacuation chamber at boiler tail usually, and the heat medium water in the pipeline of smoke evacuation chamber communicates with heat medium water in the body of heater vacuum chamber.Because boiler when work heat medium water temperature is more than 85 ℃, and the condensation temperature of flue gas causes most of flue gas that condensation can not take place between 55-65 ℃, energy-saving effect is bad.
Three, summary of the invention
The purpose of this utility model is that a kind of finned tube that adopts of design is main heated element and the vacuum boiler that significantly improves condenser efficiency.
The technical solution of the utility model is: this utility model is made up of body of heater, heat exchanger and condenser, wherein strile-back chamber, vacuum furnace chamber of the burner hearth, the front smoke box that are surrounded by fin and pipeline of oven body part formed, there is heat medium water its inside, dress heat exchanger tube in the vacuum furnace chamber first half, heat exchanger is made up of heat exchanger tube, collection case, water inlet and delivery port, the burner hearth right part is provided with condenser, be equipped with finned tube group connected in series in the condenser, finned tube group water inlet is linked the return pipe of boiler, and the delivery port of finned tube group is linked the water inlet of heat exchanger by pipeline.
The beneficial effects of the utility model: the furnace heating surface that fin and pipeline surround is big, and water capacity is little, and boiler startup is fast.The front smoke box temperature is low, long service life.Condenser temperature reduces, and energy recovery efficient is higher, reaches the purpose of energy-conserving and environment-protective.
Four, description of drawings
Accompanying drawing 1 is the utility model overall structure schematic diagram.
Accompanying drawing 2 is that A-A is to cross-sectional view.
Five, the specific embodiment
This utility model is by body of heater 1, heat exchanger 8 and condenser 6 are formed, body of heater 1 adopts seamless steel pipe 3 and fin 4 to surround the convection heating surface of center strile-back type burner hearth 1-1, seamless steel pipe 3 is inner to communicate with strile-back chamber 2 and vacuum furnace chamber 7 inside of front smoke box, it is inner for vacuum state and be marked with heat medium water 5. heat medium waters 5 and be high purity water, to the boiler No oxidation corrosion, contain small amounts of inorganic salt, make the boiler non-scaling. during burner 11 work, strile-back chamber 2 of front smoke box is water-cooled structure, forming passage by inside and outside two coaming plates is communicated with the upper and lower cavity of vacuum boiler, constitute the passage of heat medium water, front smoke box is cooled off, lower than plain cylindrical furnace temperature, thereby longer service life. the heat exchanger tube 8-1 of heat exchanger 8 is housed in vacuum furnace chamber 7 first halves, heat exchanger 8 is by heat exchanger tube 8-1, collection case 8-2, water inlet 8-3, delivery port 8-4 and cleaning cover plate 8-5 form. and wherein heat exchanger 8-1 is a straight tube, after the boiler heating, the heat of steam is by heat exchanger tube 8-1 output heat energy. and heat exchanger 8 two ends are provided with collection case 8-2, can open during maintenance, clear up with utensil heat exchanging device 8 surperficial dirts such as hairbrush. be equipped with finned tube group 6-1 connected in series in the condenser 6, its material adopts steel-aluminum composite fin tube or stainless steel finned tube, the water inlet 6-2 of finned tube group 6-1 links the return pipe 9-1 of boiler, the delivery port 6-3 of finned tube group 6-1 links the water inlet 8-3 of heat exchanger 8 by pipeline 9-2, make condenser 6 communicate with the recirculated water of heat exchanger 8 inside. can significantly reduce exhaust gas temperature during boiler work, and utilize smoke discharging residual heat heating recirculated water by heat exchanger 8. between the finned tube water inlet 6-2 of condenser 6 and the delivery port 6-3 valve 10 is arranged, its effect is identical with plain cylindrical furnace, no longer describe in detail herein. the utility model has the advantages that: the flue gas condensing waste heat recovery heating surface of forming by spiral fin coil, can increase 5-10 doubly with respect to the light pipe heat transfer area. increase the fin surface fluid turbulent, heat transfer coefficient improves 1-3 doubly. and vacuum furnace chamber system water capacity is little, boiler startup is fast. and the front smoke box temperature is low, long service life. condenser temperature reduces, energy recovery efficient is higher, reduce emission of harmful substances simultaneously, reached the purpose of energy-conserving and environment-protective.
