Abstract

The invention provides a gasification gas furnace which comprises a gas making furnace, a waste gas exhaust pipe, a fan, a tar wastewater purifier and a cooking range. The gasification gas furnace is characterized in that an oxygen supply nozzle is an annular cone frustum cavity which is arranged around the inner peripheral wall of the lower part of the gas making furnace, and an inline is a nozzle surface. The invention has the advantages that: 1, materials in the furnace can be fully gasified, and the utilization rate of the materials is high; 2, combustion holes of the cooking range are not easy to block without usually cleaning, and the use is convenient and simple; 3, tar recycled through the purifier is effectively utilized; and 4, no smoke is generated when the materials are filled, the environment is purified and the health of the operator is protected.

Description

A kind of gasification gas furnace

Technical field: the present invention relates to a kind of improved gasification gas furnace, particularly a kind ofly gasify thoroughly, burner port is difficult for being blocked, tar reclaims, use in the smokeless gasification gas furnace of filler.

Technical background: problems such as existing gasification gas furnace operation easier is big in order to solve, kitchen range unreasonable structure, I have applied for that a kind of name is called the patent application of " energy-efficient gasification gas furnace easy to use ", see accompanying drawing 1, it is made up of producer 1, waste gas comb 2, blower fan 5, tar and waste water primary purification device 6, tar and waste water secondary purifier 7, kitchen range 8, oxygen supply nozzle 9.Its advantage is: removed branch's oxygen supply tube etc., simple and compact for structure, easy to operate easy grasp, reduced the waste of environmental pollution and tar, in the use, it still has weak point: mainly show: one, materials are not fully gasified in the stove, the utilization rate of materials is not high, this is because be by 9 oxygen supplys of oxygen supply nozzle in the stove, and oxygen supply nozzle 9 is the rhombus cone, its surface area is little, its oxygen supply radiation scope is little, especially those are far away and to be positioned at the other oxygen supply that materials obtain of stove perisporium very limited from oxygen supply nozzle 9, so that gasification result is not so good; Two, the burner port of kitchen range 8 is blocked easily, need often to remove, make troubles to use, though its problem is the purification through clarifier, but in combustion gas, also still there are a certain amount of tar, moisture and impurity etc., when combustion gas rose to the burning of kitchen range 8 burner port places, its tar that carries, moisture and impurity etc. can make burner port blocked attached to the burning of burner port place; The burner port cloth cover of kitchen range 8 only is the inclined-plane of rounding frustum, firepower a little less than; Three, the tar that reclaims by clarifier fails effectively to be utilized, and this is because the outlet of the return duct of clarifier 6 bottoms is positioned at by the side of oxygen supply nozzle 9, and its tar, moisture etc. directly drop on producer 1 bottom, the utilization of can not being gasified fully; Four, in use during filler, there is molten cigarette to emerge, contaminated environment and infringement health of operators, because during filler, need open the bell at producer 1 top, though blower fan 5 stops air feed, the flue gas in the stove still was easy to overflow from stove in the period that bell is opened.

Summary of the invention: at the problem that above-mentioned gasification gas furnace in use exists, main purpose of the present invention is, proposes the gasification gas furnace that materials can fully gasify in a kind of stove; Secondary objective is, propose a kind of kitchen range burner port be not easy tar blocked, that reclaim can effectively be utilized, be used in the smokeless gasification gas furnace of filler.

Can realize the object of the invention by following technical proposals, a kind of gasification gas furnace comprises producer, waste gas comb, blower fan, tar and waste water clarifier, kitchen range, it is characterized in that, the oxygen supply nozzle is an annular taper platform cavity body, and it is provided with along producer bottom internal perisporium, and the inclined-plane is a nozzle face.

The cross section angle of nozzle face is 45～80 °.

Not blocked for preventing the kitchen range burner port, in the kitchen range inner chamber, be provided with circular horizontal baffle.

For improving the kitchen range firepower, the inclined-plane and the bottom surface of kitchen range rounding frustum are evenly equipped with burner port.

The outlet of tar and waste water clarifier return duct is positioned at oxygen supply nozzle top furnace chamber central part.

Flue gas is overflowed in the stove when preventing filler, is provided with the funnel-form baffle plate that stretches to the body of heater inner chamber at body of heater open top end place.

The cross section angle of funnel-form baffle plate is 45～80 °.

Effect of the present invention is: 1, materials can fully be gasified in the stove, the utilization rate height of materials, this is because change has taken place in the oxygen supply nozzle in the stove, make the annular taper platform cavity body of big tens of times of an oxygen supply nozzle area into by a little rhombus cone, its oxygen supply swept area is big, and by perisporium to the central part radiation, can make that materials obtain abundant oxygen supply in the stove, make its gasification fully; 2, the burner port of kitchen range is not easy blocked, do not need frequent removing, easy to use, this is, this device improves the kitchen range structure, be provided with circular horizontal baffle in the kitchen range inner chamber, this horizontal baffle can stop tar, moisture and the impurity of the overwhelming majority of carrying in the combustion gas, has avoided the blocked situation of burner port frequently to take place; 3, the tar that reclaims by clarifier has obtained effective utilization, this is because the outlet of the return duct of clarifier is positioned at the central part of oxygen supply nozzle top, its tar, moisture promptly drop on the temperature gasification and high district when falling, they carry out the cracking second time rapidly and change into fuel gas; The firepower of kitchen range is strong, and this is because be furnished with burner port in the bottom surface of kitchen range rounding frustum, and combustion gas can directly be risen and be entered the burner port burning, and kinetic energy does not have loss; 4, in use during filler; there is not molten cigarette to emerge; environment is purified; health of operators is protected; this is provided with the funnel-form baffle plate that stretches to the body of heater inner chamber because stop air feed when blower fan at body of heater open top end place, and this baffle plate makes under the baffle plate that the hot gas flow velocity at the back side is accelerated, pressure reduces; the hot gas overwhelming majority flows towards last along the baffle plate lower back in the stove, and funnel-form its centre portion feed opening then seldom has flue gas to overflow.

Below in conjunction with drawings and Examples the present invention is further set forth:
