Description
Technical field
The present invention relates to chemical production field more particularly to a kind of spray heads for biomass cracking gases purification.
Background technology
The biomass garbages material such as agricultural crop straw, wood sawdust can be high heating value by biomass thermal-cracking gasification integration technology
Imflammable gas, and the secondary pollution problem generated can be burned to avoid biomass garbage, it is considered to be it is a kind of more promising
Technology.In biomass thermal-cracking gasification integration reactor, hot pyrolysis gas extreme temperatures, and contain significant component of tar,
This is great for the qualitative effects of final product imflammable gas, therefore cooling to thermal cracking gas and Study on purification are to closing weight
It wants.The cooling of traditional hot pyrolysis gas, there are commonly glass bulb cooling, row heat exchanger and plate heat exchangers etc..These types is cold
But for mode due to being indirect cooling, cooling efficiency is relatively low, and cannot be removed effectively the carbon particle in thermal cracking gas.Meanwhile
Prodigious in cooling power, the size of cooler necessarily increases, and leads to that equipment is huge, cost increases.And liquid sprays
The type of cooling be using the direct contact heat transfer between the larger cryogenic liquid and high-temperature gas of specific heat capacity, therefore cooling efficiency compared with
Height can effectively remove tar in cracking gas, purify cracking gas.
Such as patent announcement CN206139364U, a kind of entitled chemical industry spray head, structure include main water supply connecting tube,
Secondary water supply connecting tube and annular spray head；Main water supply connecting tube is cylindrical to be vertically arranged, and the quantity of secondary water supply connecting tube is four
A and connect with the lower end of main water supply connecting tube, annular spray head is circular and passes through four secondary water supply connecting tubes and main confession
Water connecting tube connects, and the bottom end of annular spray head and outboard end are provided with multiple hole for water sprayings；Main water supply connecting tube, secondary connection of supplying water
The inner cavity of pipe and annular spray head is connected to.The patent gives a kind of rough idea of spray head, passes through annular spray head
Design can be to avoid interfering with each other between shower water column, but the spray head atomizing effect that the Patent design goes out is poor, water consumption
Big and shower water is ring-type, bad to the heat exchange and clean-up effect of cracking gas.
Many design schemes in relation to spray head are also disclosed in patent gazette, but the design of its spray head is mostly water spray
Hole is arranged in array or circumference array in the plane of spray head lower end, due to the influence of gravity, periphery water column meeting when spray
It more evacuates and internal water column is more intensive, it is bad to the heat transfer effect of cracking gas；And the spray angles of common spray head are big
Can only achieve 60-90 ° more, the area coverage of shower water is not wide, when use need to add spray head can be only achieved it is ideal
Heat transfer effect.How designing one kind, there is spray effect, the big high efficiency spray head of spray angles to become the research pair of the present invention
As.
Invention content
In order to solve deficiency in the prior art, the purpose of the present invention is to provide one kind having spray effect, and can
Realize the spray head for biomass cracking gases purification of wide-angle high efficiency spray.
To achieve the above object, the present invention uses following technical scheme：
A kind of spray head for biomass cracking gases purification comprising main body, nozzle and air inlet pipe, nozzle are fixed on main body
The inlet end of bottom, air inlet pipe accesses purified biomass cracking gases, and the outlet side of air inlet pipe extends at the top of main body
Body interior is simultaneously connected to the inner cavity of nozzle, and the body interior forms the cavity around air inlet pipe setting, is set at the top of main body
There is the water inlet of connection cavity, the bottom of cavity is connected to the inner cavity of nozzle；The nozzle is in truncated cone-shaped, is set on the bottom surface of nozzle
There is the first hole for water spraying, multiple second hole for water sprayings are equipped at intervals on the side of nozzle.
Further, the cavity is toroidal cavity, and cavity bottom is in up big and down small coniform.
Further, the lower part of the cavity is equipped with water inlet groove, and water inlet groove is connected to the inner cavity of nozzle.
Further, first hole for water spraying is one, and the first hole for water spraying is located at the circle centre position of nozzle bottom surface.
Further, the multiple second hole for water spraying is along the circumferential direction located on the side of nozzle at equal intervals.
Further, the cross section of first hole for water spraying and the second hole for water spraying is circle.
The present invention uses above technical scheme, has the advantages that：By introducing purified high speed in air inlet pipe
Flow back cracking gas, realizes misty spray, and avoid the influence for being introduced directly into air for final product cracking gas quality；It is logical
Misty spray is crossed, the heat exchange area of shower water and biomass cracking gases is increased, greatly improves spray process for cracking gas
Cooling-down effect improves the utilization ratio of water resource；Hole for water spraying is respectively set in head of the nozzle and side, greatly expands spraying
Area makes spray angles reach 140 ° or more, effectively can carry out tar removing purified treatment to biomass cracking gases.
Description of the drawings
The present invention is described in further details below in conjunction with the drawings and specific embodiments：
Fig. 1 is a kind of overall structure sectional view of spray head for biomass cracking gases purification of the present invention；
Fig. 2 is the upward view of nozzle in the present invention.
