Abstract

The present invention has been designed to provide a solution to problems with conventional gasifiers which operate by having fuel introduced at one end of a gasification retort and gas and residues removed from the other end. This frequently results in powdered char residues being ejected with the gas, causing increased gas clean-up requirements. The present invention provides a solution to this problem by removing the gas from the retort at the fuel inlet end via the fuel feed system which is preferably a combined ram and scroll feed providing a supply of fuel under anaerobic conditions.

Description

Gasifier feed system
Background technology
Existing producer gas generator is to adopt at gasification reaction jar one end to feed fuel, operates from the mode of the other end combustion gas and residue.This mode often causes the powder carbon residue to be discharged with waste gas, causes that the requirement of tail gas clean-up improves.
Summary of the invention
The objective of the invention is to provides a solution at the problems referred to above, and this scheme is a kind of fuel-feed of employing system, and waste gas is discharged from the fuel inlet end of retort.Described fuel-feed optimum system choosing is plunger and spiral combined feed system, provides fuel under anaerobic environment.
Preferably, also be provided with an intermediate cavity between plunger feeder and feeding screw, this intermediate cavity was used for before fuel is transported to feeding screw, accepted from the fuel of one or more plunger feeder inputs, to assist the fuel decomposition process.In order to increase or change fuel feed, make flow fuel steady, more than one plunger can be set.In the feed system casing, a device for the waste gas cooled discharge is arranged, described waste gas produces in retort.Since during fuel first pass retort the residence time of short duration, oils and tar are non-degradable, they can or enter retort from coke export by feed system and further gasify.For the too early gasification that prevents to cause owing near the high-temp waste gas that distributes and the high temperature in the retort, the fuel requirement of input is cooled off in feed system.
Description of drawings
Below by specific embodiments and the drawings the present invention is described.
Fig. 1 is the longitudinal diagram of the retort of producer gas generator, and this retort fuel-feed device and gas barrier are combined, and comprises intermediate cavity and single plunger;
Fig. 2 is the A-A sectional view of the mechanism of band intermediate cavity and single plunger;
Fig. 3 is the A-A sectional view of the mechanism of band intermediate cavity and double plunger.
Embodiment
Suitably the dried fuel of size is transported to hopper 1, this dried fuel is gasification in the retort 15 of rotation, enter plunger pipeline 12 from 1 li material tenesmus of hopper, simultaneously, plunger feeder 2 is retracted by hydraulic plunger 10 along guide rail 3, plunger feeder 2 returns, and makes fuel to gate valve 11 extruding of closing.Then, gate valve 11 is opened, and the passive strength cylinder of fuel pellet feeder 2 is pushed the spirochete 4 by power unit 5 drivings to.Fuel enters producer gas generator from spirochetal pipe end 9.
As the preferred embodiments of the present invention, between plunger feeder and spirochete, be provided with an intermediate cavity 13.Described intermediate cavity or feeding screw can connect one with the upper plug feeder, and this helps changing the feed rate of fuel or makes that to be transported to spirochetal flow fuel steady.Spirochete is provided with around a hollow center post 6, and at cleaning section, oils of discharging from gaseous product and tar enter retort by this hollow center post 6 with fuel.
Because the high temperature of the retort of producer gas generator and the gas that distributes, in order to prevent too early gasification, spirochete is arranged in the static pipeline 16, the water cooling that this static pipeline 16 utilizes through inlet/outlet 8 input and output, this static pipeline 16 is sealed by tightness system 17 in the position against the retort of rotating.
Cooling jacket extends to spirochete end 9, and fuel enters the retort of producer gas generator from spirochete end 9.Waste gas outlet also is arranged in the static pipeline 16, and waste gas is discharged by tobacco pipe 14 via the pipeline 7 of retort 15 inside that are connected to producer gas generator.Coke is discharged by spirochete 10 and rotary valve, and this spirochete 10 and rotary valve stop waste gas to leak and air admission.
Above-mentioned detailed description is at the specifying of possible embodiments of the present invention, and this embodiment is not the claim in order to restriction this law, does not allly break away from equivalence of the present invention and implements or change, all should be contained in the claim of this case.
