Description
Technical field:
The present invention relates to a kind of stalk gasifier.
Background technology:
Straw is a kind of source carbonaceous fuel very widely, but, because the lighter weight of straw, fuel such as the relative coal of its volume are bigger, and can produce a large amount of dense smoke when burning, so, even straw is not effectively utilized in the rural area that the energy lacks very much yet, and, occupy the arable land for preventing straw in some occasion away from dwelling house, usually in ploughing, just straw is burnt, cause the significant wastage of the energy; In addition, adopt the straw that directly burns, need operations such as dry and shearing as the energy, and because the straw hollow light weight, its combustionvelocity is fast, so, need the personal management in use, bring many inconvenience to the user.
Stalk gasifier is a kind ofly to make stalk generation cracking and generate the device of combustion gas under anoxic condition.This kind vapourizing furnace can make stalk produce combustion gas under compressed state, so stalk gasifier can overcome the deficiency that direct burning straw brings.With regard to stalk gasifier, the leading indicator of estimating its performance quality generally comprises the quality and quantity that generates combustion gas, and whether soot emissions has these three aspects of pollution.Under normal conditions, the quantity of vapourizing furnace production combustion gas determines the size of its volume, and promptly the quantity of vapourizing furnace aerogenesis is directly proportional with its volume, but the increase of vapourizing furnace volume can cause the raising of its cost of manufacture, also can take corresponding big space simultaneously; What of impurity such as contained tar in it are the quality of combustion gas quality mainly be meant, but as long as this class impurity filter through water cooling just can eliminate, and it is more economical that the problem of key is what position energy the water cooling filtration unit is arranged on; And stalk after cracking formed cigarette ash proportion usually less than air, so stalk gasifier will be provided with the cigarette ash treatment unit usually.
The name of Chinese patent 2568660 bulletins is called " energy saving and environment friendly stalk gasifier " and provides a kind of structure of utilizing stalk to produce the vapourizing furnace of combustion gas.This vapourizing furnace comprises body of heater and be arranged on the intravital vaporizer of stove, and feed, and pressing device.This device can convert biomass wastes such as stalk in the stove to the fuel of gasification, and by being arranged on the intravital annular passage of going up of stove, parts such as lower straight duct and air outlet and refrigerated separation purifying box purify vaporising fuel.Though this vapourizing furnace can make stalk produce inflammable gas continuously by scission reaction under the situation of limit oxygen,, what the vaporizer of this vapourizing furnace adopted is column construction, and the vaporizer of column construction is unfavorable for the combustion gas discharge influencing its gas production rate; Simultaneously, the fire grate that is provided with because of the vaporizer bottom adopts straight-bar shape structure, cause the contact area between fire grate and the stalk less, and contact area is a major cause that influences gas production rate for a short time between the two.
Summary of the invention:
The purpose of this invention is to provide a kind of utilization and increase furnace chamber spatial mode and solve combustion gas and yield poorly, can also solve the stalk gasifier of cigarette ash pollution problem simultaneously.
Stalk gasifier proposed by the invention comprises a furnace shell that has a loam cake and is installed in the fire grate assembly of the furnace chamber lower region in this furnace shell, and what this fire grate assembly comprised fixed grate and was arranged on the fixed grate central region controls the moving grate of its rotation or swing by controlling organization.
The side arm of described furnace shell is provided with the insulation interlayer, and its top is equipped with and is used for and loam cake flange connecting dish, and the shaft section of its inwall is big up and small down trapezoidal, also is provided with molten grey pond in the bottom of furnace shell.
Described loam cake is to be made of the double-deck plate that is separated with certain distance, and is provided with a feeding port at the middle part of loam cake, and a vision slit and a venting hole that is used to discharge combustion gas in the stove are set on its side.
Described fixed grate is made of the inclination fire bars that keeps at a certain distance away, and its central region is provided with circular port, and the moving grate that is made of the straight shape fire bars that is installed on the rotation axis is installed in this circular port.
Described controlling organization has the drive sprocket assembly that is arranged on the ring flange and is arranged on the outer wall of molten grey pond and driven sprocket assembly that an end and moving grate join, is provided with travelling belt between drive sprocket assembly and the driven sprocket assembly.The drive sprocket assembly has the main chain wheel that the resting support in tape spool hole, a center and can rotate along axis hole, and the end of main chain wheel is provided with a handle, and its middle part is provided with head sprocket; The driven sprocket assembly has the supporting sleeve in a tape spool hole and one and passes the major axis that supporting sleeve is all extended at axis hole and two ends, and major axis right-hand member level is passed molten grey pond and moving grate joins.
Described molten grey pond is provided with a water inlet pipe and a blow-off pipe that is used for discharging molten grey pond water ash mixture.
Stalk gasifier proposed by the invention adopts fixed grate and the moving grate that is made of the inclination fire bars, and the inclination fire bars can increase the contact area between furnace chamber and the stalk, so, this inclination fire bars can make stalk gasify fast when not increasing cost of manufacture and volume, and also can allow the cigarette ash after gasifying flow to the position of the moving grate of central region, can it be sent in the molten grey pond easily in the mode of rotating or swing through moving grate, and make cigarette ash after molten grey pond purifies, can not cause any pollution environment; In addition, the furnace chamber of this vapourizing furnace adopts the structure of falling the trapezoid, and the furnace chamber of falling the trapezoid is very beneficial for the combustion gas come-up, can further increase the output of combustion gas.
Description of drawings:
Accompanying drawing 1 is the cross-sectional view of the example of a proposed by the invention enforcement of straw gasification stove;
Accompanying drawing 2 is embodiment surface structure synoptic diagram of fire grate assembly 2 among Fig. 1.
