Abstract

Provided is an efficient energy-saving stove which can produce hot water or steam when an iron pot is used for cooking. The efficient energy-saving stove comprises a fire grate, a furnace, a pot shell, the iron pot, a convection fire tube, a deduster, a coiler, a flue and an induced draft fan. The iron pot is directly used for cooking. The fire grate, the furnace, the pot shell and the convection fire tube constitute a small boiler used for producing the hot water or the steam. The efficient energy-saving stove is structurally characterized that the furnace and the pot shell are in a cylindrical structure, a convection heating surface pipe is a big-diameter fire tube, and smoke outlets of a combustion chamber are located at the upper end of the furnace and are uniformly distributed around the furnace. A heat preservation layer is arranged outside the stove, and a coiler preheating device is arranged in the deduster.

Description

Efficient energy-saving stove

Affiliated technical field

The utility model relates to a kind of kitchen range, the kitchen range that especially act as a fuel with coal, firewood and biologic grain.

Background technology

At present, most of kitchen range that use are uncovered on the market, the added iron pan of stove, and the heat that fuel produces is except iron pan directly absorbs a part of heat, and all the other heats are along with flue gas directly enters in the atmosphere.Have now a kind of process to improve kitchen range, except the direct absorption portion heat of iron pan, all the other heats through convection heat transfer' heat-transfer by convection, have reduced exhaust gas temperature along with flue gas is sucked among the waste-heated water-tank by air-introduced machine, play certain energy conservation and consumption reduction effects.But above kitchen range ubiquity problem and shortcoming have: 1, dangerous: deposit hot water or deposit pressure part and adopt irrational square structure, there is unstability in square structure, easily distortion, thus cause cylindrical shell to damage, weld seam breaks.2, be not durable: heating surface pipe adopts water pipe, in the pipe easily fouling stop up, cause booster, shorten kitchen range service life.3, not energy-conservation: the setting of burner hearth outlet flue is lower, and fuel has little time fully burning and just pulled out away by air-introduced machine; Exhaust gas temperature is higher; Without Insulation, radiation loss is more.4, not environmental protection: dust arrester is not set.

Summary of the invention

The shortcoming that exists in order to solve traditional kitchen range, the utility model provides a kind of kitchen range, produces hot water or steam in the iron pan cooking, has safe, durable in use, the energy-conserving and environment-protective characteristics of use.

The technical scheme that the utility model is dealt with problems is: efficient energy-saving stove is to be made of fire grate, flue, shell, iron pan, convection current smoke pipe, deduster, coiled pipe, flue and air-introduced machine critical piece.Iron pan is directly used in cooking, and fire grate, flue, shell, convection current smoke pipe consist of a miniature boiler, for generation of hot water or steam.Main flue gas flow is, the heat that fuel produces on the fire grate is at first directly absorbed by iron pan and flue, all the other heats are along with flue gas is inhaled into smoke pipe in the shell, the water outer with smoke pipe carries out convection heat transfer' heat-transfer by convection, then flue gas enters deduster through header, flue, after carrying out the cooling of water film dedusting and coiled pipe, enter atmosphere through air-introduced machine.Flue is the crux radiation heating-surface, and shell is to deposit pressure part, all adopts the columnar structured of national Specification, and welding point adopts banjo fixing butt jointing, and this structural stability is good, and safety coefficient is high; Convection heating surface tube adopts the major diameter smoke pipe, and Non-scale stops up in the pipe, can booster, prolonged kitchen range service life; The burner hearth outlet flue is arranged on the flue upper end, and everywhere uniform, and fuel is fully burned in burner hearth, produces high-temperature flue gas and on average flows to four outlet flues, and top iron pan is heated evenly.Heat-insulation layer is housed outside kitchen range, reduces thermal loss.Be provided with the coiled pipe device in the deduster, flue gas washes away up and down coiled pipe, effectively reduces exhaust gas temperature, improves inflow temperature; Deduster is to utilize dividing plate to change dust flow direction in the flue gas, and dust falls into water layer at inertia and Action of Gravity Field, reaches the dedusting purpose.

The beneficial effects of the utility model are: these kitchen range provide hot water or steam in the iron pan cooking.Have compact conformation, use safe, durable in use, energy-conserving and environment-protective.

The specific embodiment

In Fig. 1, Fig. 2, these kitchen range are made of fire grate 1, flue 2, shell 8, iron pan 23, front smoke pipe 3, rear smoke pipe 5, header 9, flue 10, deduster 11, coiled pipe 12, air-introduced machine 14.Flue 2 tops are divided into cylindrical shape, and the bottom is divided into horn mouth, and burner hearth outlet flue 6 is arranged on flue 2 upper ends, and uniform 4 points, and with front smoke pipe 3, rear smoke pipe 5, header 9 series windings, the smoke pipe left-right symmetry makes 6 four inner tube smoke flows of burner hearth outlet flue identical.At shell 8 steam (vapor) outlet 19, hot water outlet 4, inspection opening 18, sewage draining exit 17, fire door 16 are set.Shell 8 outer installing heat-insulation layers 7.In order to ensure safety, at steam (vapor) outlet 19 pipeline device changeover valves 20, safety valve 21, Pressure gauge 22.

In Fig. 3, the deduster 11 interior three road dividing plates 24 that arrange change flue gas flow direction, make dust vertically fall into water layer 27.In deduster 11 upper smoke headrooms, arrange coiled pipe 12, flue gas washes away up and down coiled pipe 12 by dividing plate 24, reduces exhaust gas temperature, improves inflow temperature.
