Description
Technical field:
The utility model 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 burning velocity 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 anaerobic condition.This kind gasification furnace can make stalk produce combustion gas under compressive 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 gasification furnace production combustion gas determines the size of its volume, and promptly the quantity of gasification furnace aerogenesis is directly proportional with its volume, but the increase of gasification 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 filter 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 treating apparatus 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 gasification furnace of combustion gas.This gasification furnace comprises body of heater and is arranged on vaporizer in the body of heater, and feed, and material pressing device.This device can convert biomass castoffs such as stalk in the stove to the fuel of gasification, and by being arranged on the last annular passage in the body of heater, parts such as lower straight duct and gas outlet and refrigerated separation purifying box purify vaporising fuel.Though this gasification furnace can make stalk produce fuel gas continuously by cracking reaction under the situation of limit oxygen,, what the vaporizer of this gasification furnace adopted is column construction, and the vaporizer of column construction is unfavorable for the combustion gas discharge influencing its gas production; 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 main cause that influences gas production for a short time between the two.
Summary of the invention:
The purpose of this utility model provides a kind ofly to be utilized the mode that increases the furnace chamber space to solve combustion gas to yield poorly, can also solve the stalk gasifier of cigarette ash pollution problem simultaneously.

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 peep hole and a steam vent 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 turning cylinder 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 conveyer belt between drive sprocket assembly and the driven sprocket assembly.The drive sprocket assembly has the main chain wheel that the bearing 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 splicing sleeve in a tape spool hole and one and passes the major axis that splicing 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 that the utility model proposes 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 gasification furnace adopts down trapezoidal structure, is very beneficial for combustion gas come-up and fall trapezoidal furnace chamber, can further increase the output of combustion gas.
