Abstract

A cabinet type biomass hot blast stove comprises a cabinet. A fuel barrel and multiple layers of heat exchange rotary liners are respectively arranged on a grate above a burning chamber in the cabinet. The lower portion of the outer wall of the fuel barrel is provided with a secondary air box tightly connected with the fuel barrel. The air inlet of the secondary air box is connected to a secondary air tube. The outer wall of the fuel barrel is provided with a plurality of secondary air holes corresponding to the secondary air box. A gas exhaust tube penetrates out of the cabinet, the penetrating end of the gas exhaust tube is provided with a jet pipe in a penetrating manner from exterior to interior, and the lower end of the jet pipe is connected to a jet fan. Each heat exchange rotary liner between the bottom layer of the heat exchange rotary liner and the top layer of the heat exchange rotary liner is connected to one gas inlet channel pipe and one gas outlet channel pipe which are respectively arranged on two sides corresponding to the heat exchange rotary liner. According to the cabinet type biomass hot blast stove, the multi-point air-distribution counter-burning technology is adopted, the stove is capable of burning completely, gas is eliminated, and environment is protected; meanwhile, since the rotary liner heat exchange technology is adopted, the hot blast stove air flow amount is maximized, and gas exhausting temperature of the hot blast stove is decreased greatly.

Description

Cabinet type biomass thermal wind furnace
Technical field
The present invention relates to a kind of stove and accessory, particularly relate to a kind of cabinet type biomass thermal wind furnace with multi-layer rotating heat exchange flue.
Background technology
At present, the following problem of ubiquity in various small-sized stove and accessorys: 1, can only burn coal, be difficult to utilize a lot of low-calorie fuel, limit fuel source, make many solid-state combustibles not only can not utilize simultaneously, become on the contrary the rubbish of contaminated environment; 2, due to hot-blast stove wind entrance for once, fuel during use in burner hearth can not fully burn, and not only causes a large amount of black smokes, and the thermal efficiency is not high; 3, flue gas flow is too short and cause the excessive problem of flue gas resistance in order to increase flue gas flow, and flue gas rises too fast, and heat transfer effect is bad; 4, smoke evacuation air-introduced machine is in the past to be all operated under the condition of high temperature, exists cost high, and maintenance rate is high, the disadvantage that spoilage is high.
Summary of the invention
There is defect and deficiency for solving above-mentioned prior art in object of the present invention, and a kind of cabinet type biomass thermal wind furnace is provided exactly.
The technical scheme adopting is:
Cabinet type biomass thermal wind furnace, comprise cabinet, bottom in cabinet is installed with fire grate, in cabinet, be positioned at fire grate below for combustion chamber, in cabinet, be positioned on the fire grate of combustion chamber top and be respectively arranged with propellant bottle and Multi-layer thermal exchange rotation inner bag, and propellant bottle and Multi-layer thermal exchange rotation inner bag divide the both sides that are located in cabinet, the upper end of propellant bottle leans out outside cabinet, the upper port of propellant bottle is provided with cover, the bottom of propellant bottle outer wall is equipped with Secondary Air box, and Secondary Air box is connected with propellant bottle air-tightness, on Secondary Air box, there is air inlet, the air inlet place of Secondary Air box is connected with secondary air channel, correspondingly with Secondary Air box on the outer wall of propellant bottle go out to offer a plurality of secondary air holes.Orlop heat exchange rotation inner bag is connected with a plurality of fireworks channel pipes that enter in cabinet, a plurality of fireworks channel pipes are connected with the combustion chamber of cabinet bottom, in cabinet, the heat exchange of the superiors rotation inner bag is connected with the smoke evacuation cylinder on cabinet top, and be connected, smoke evacuation cylinder passes outside cabinet, the end ecto-entad of smoke evacuation cylinder traversing through end has penetrated a jet pipe, the lower end of jet pipe is connected with jet blower, each heat exchange rotation inner bag between orlop heat exchange rotation inner bag and the superiors' heat exchange rotation inner bag is all connected with fume inlet passage pipe and smoke-outlet flue pipe, and fume inlet passage pipe divides and is located at the both sides that heat exchange rotation inner bag is relative with smoke-outlet flue pipe.On the roof of cabinet, be positioned at a plurality of heat exchange rotation inner bag one side and offer fresh air inlet, air inlet place is connected with air intake blower fan, at least offers a hot-blast outlet on the outer wall of bottom of cabinet bulk, on the outer wall at cabinet middle part, at least offers a natural wind entrance.
Major advantage of the present invention:
1, the present invention adopts the anti-burning technology of multiple spot air distribution, and boiler can fully be burnt, again can smokeless environment-friendly.
2, the present invention has adopted rotation courage heat transfer technology, and hot-blast stove fume flow is maximized, and greatly reduces the exhaust gas temperature of hot-blast stove.
3, the present invention has adopted smoke evacuation spraying technique, and chimney height is significantly reduced.
4, due to sufficient combustion, the tar content in flue gas is very low, adds that rotation courage space is larger, and boiler seldom needs deashing in running, even if deashing is also very simple, convenient.
5, because the anti-burning technology ignition temperature of multiple spot air distribution is moderate, solved the coking problem in indivedual biomass fuel combustion processes.
6, owing to adopting smoke evacuation spraying technique, solved the air-introduced machine of in the past discharging fume be operated under the condition of high temperature expensive, high maintenance rate, the drawback of high spoilage, because this smoke evacuation technology blower fan is operated in normal temperature state, adopt common blower fan to solve the smoking problem of boiler.
