Abstract
The utility model provides a smoke and dust suppressing brown coal gasification furnace. The combustion chamber (5) of the gasification furnace (1) is connected with a smoke exhaust pipe (6) outside; the smoke exhaust pipe (6) is communicated with a smoke-removal tower (7); an oil container (8) is communicated with the ignition chamber (11) of the smoke-removal tower (7) via an oil pipe (9), wherein the ignition chamber (11) is connected with a fan (12) via a pipeline. In the process of igniting the brown coal gasification furnace, the utility model discharges large amounts of smoke into the smoke-removal tower and completely burns out the smoke with a burner (16), thereby the utility model has the advantages that the brown coal is completely burned out, the smoke and dust is completely eliminated, the gas into the gas furnace is environmentally-friendly and clean, the calorific value is high, and the device is conducive to human health.
Description
Technical field:
The utility model belongs to the brown coal hydrogasification furnace apparatus technical field of structures that a kind of grouping of the world economy gives gas.
Background technology:
It is existing that to be used for to employing brown coal system coal gas such as hotel, restaurant or unit dining rooms be that the system gas boiler is directly linked to each other with gas-cooker with the device of coal-fired gas kitchen, this device has possessed decoking and desulfurization technology at present, as the patent No. be: 200720103468.7 brown coal hydrogasification furnace apparatus structure technologies that are called " brown coal environment protection energy saving stove ", this technology adopts desulfurization case and decoking tower, the decoking tower and the desulfurization case that is shaped as the airtight cavity volume of cylindricality of the airtight cavity volume of the cylindricality of being shaped as are arranged by pipe connection, and top of chamber is provided with water spray system in the decoking tower; In the desulfurization case, be provided with the medium that 1-6 pull-up sulphur basket contains filtering gas and reach decoking and desulfurization.Though this patent application can realize decoking and desulfurization during brown coal burnings, still have the smog environment of stretching, the contained volatilization composition of ature of coal not only produces tar, lightweight oil, methane and H in retort section generation destructive distillation
2Materials such as S, coal body also can produce flue dust, especially behind the truce banking, when reusing, have some smog in short-term and discharge, and the discharge of smog not only pollutes the environment, and atmosphere pollution is gone back the smell people that chokes, and human respiratory is produced harm; And cause the ature of coal burning insufficient, the waste natural energy source.
Summary of the invention:
The purpose of this utility model provides a kind of brown coal sufficient combustion that can make, a kind of smoke prevention and dust control brown coal hydrogasification stove that flue dust is eliminated fully in order to overcome the weak point that flue dust that above-mentioned prior art exists can't eliminate just.
The utility model is achieved by the following technical solution.
The utility model is by being made up of vapourizing furnace, filtration unit, burner and chimney, it is characterized in that, in the combustion chamber of vapourizing furnace to being externally connected with pipe, this pipe is communicated with a smoke abatement tower, the structure of smoke abatement tower is: the tower body outside is a closed cylinder, the inner upper of cylindrical shell is divided into the combustion chamber, offers uniform Small Holes on the cylindrical shell in the scope of combustion chamber; In the middle of the inner lower of cylindrical shell is divided is igniting chamber, is provided with burner at igniting chamber, is provided with oil burner nozzle below burner, is provided with a fuel tank and is communicated with oil burner nozzle by oil pipe; Around the lower section igniting chamber of smoke abatement tower cylindrical shell, be provided with refractory materials; Igniting chamber has a gas blower by pipe connection.
The beneficial effects of the utility model are, the brown coal smog in the vapourizing furnace is fully burnt, and have avoided the generation contaminate environment of coal smoke mist, and the harmful to human respiratory health has environmental protection, energy-conservation remarkable advantage.
Further set forth the utility model content below in conjunction with drawings and Examples
Description of drawings:
Fig. 1 is a body of heater one-piece construction synoptic diagram;
Fig. 2 is the utility model apparatus structure synoptic diagram.
Embodiment:
The utility model is made up of vapourizing furnace 1, filtration unit 2, burner 3 and chimney 4, it is characterized in that, in the combustion chamber 5 of vapourizing furnace 1 to being externally connected with chimney 4, this chimney 4 connects a pipe 6, this pipe 6 is communicated with smoke abatement tower 7, the structure of smoke abatement tower 7 is: the tower body outside is a closed cylinder 13, and the inner upper of cylindrical shell is divided into burning smoke chamber 15, offers uniform Small Holes 14 on the cylindrical shell in the scope of burning smoke chamber; In the middle of the inner lower of cylindrical shell is divided is igniting chamber 11, is provided with burner 16 at igniting chamber, is provided with oil burner nozzle 10 below burner, is provided with a fuel tank 8 and is communicated with oil burner nozzle 10 by oil pipe 9; Around the lower section igniting chamber 11 of smoke abatement tower cylindrical shell, be provided with refractory materials 17; Igniting chamber 11 has a gas blower 12 by pipe connection.
Mode of operation of the present utility model is to pass through chimney 4 pipe connection between vapourizing furnace 1 and smoke abatement tower 7.When the brown coal gas furnace is enabled once more; chimney 4 pipelines of vapourizing furnace are communicated with smoke abatement tower 7; during vapourizing furnace 1 igniting; just the incendiary coal can produce some smog; and the utility model smoke abatement tower 7 is connected with the combustion chamber 5 of vapourizing furnace 1 by pipe 6 connection chimneys 4 pipelines; the smog that produces is introduced into smoke abatement tower 7 after opening and sending cigarette valve 19; light the burner 16 in the smoke abatement tower 7 internal combustion smoke-boxes 15; burning smoke chamber metalwork is heated; again the smog of vapourizing furnace being introduced nozzle 18 emits; this moment is open-minded with the fuel tap 20 on the oil pipe 9 of fuel tank 8 connections; by oil burner nozzle 10 in igniting chamber 11 oil spouts; moment, smog was just by the diesel oil flame ignition; igniting chamber 11 is opened 21 air blast of air distribution valve by the gas blower 12 of pipe connection; moment produces high temperature in the closed cylinder 13 of smoke abatement tower; owing to offer uniform Small Holes 14 on the closed cylinder; the air-flow that aperture provides makes smog burn rapidly in burning smoke chamber 15; very fast smog is thoroughly burnouted, the refractory materials 17 that is provided with around the lower section igniting chamber 11 of smoke abatement tower cylindrical shell plays the heat insulation and provide protection to smoke abatement tower 7.After 5 trouble-free burning of the combustion chamber of gas furnace 4, close the oil pipe 9 of fuel tank 8 rapidly, the low smoke of generation still can be introduced into smoke abatement tower 7 and burn totally voluntarily.
