Description
Technical field
The utility model relates to a kind of gas dust-removing devices of laboratory tube furnace, more particularly to one kind to be used for high-temperature tubular
The collection filter device at tail gas end in furnace.
Background technique
Tube furnace is a kind of to can be used in the vacuum either various environment such as nitrogen, argon gas carrying out setting for pyroprocess
It is standby.This equipment generally requires to seal, while being equipped with air inlet and gas vent, and air inlet and gas vent are respectively provided at tubular type furnace cavity
Front-end and back-end.
Some chemical reactions and the discharge of high-temperature gas are often associated with for the pyroprocess occurred in tube furnace.It is right
It is gas in some high temperature and is at low temperature that the reactant of liquid or solid will when it by gas vent when being discharged
It is attached at gas vent valve, to be easy to cause gas vent valve blockage.
Utility model content
The purpose of this utility model is exactly to provide one to solve the problems, such as that existing tube-typed grate stomata valve is susceptible to plugging
Collection filter device of the kind for tail gas end in high temperature process furnances, is adsorbed and collected filtering, structure to the gas in tube furnace
Simple and easily replacement, effectively removes particulate matter in tail gas, to prevent the blocking of tube-typed grate stomata valve.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of collection filter device for tail gas end in high temperature process furnances, including tube furnace, the cavity tail end of tube furnace
Interior to be equipped with heat preservation pipe plug, tail end is connected with gas vent, it is characterised in that:
Connect an exhaust gas filter in the cavity tail end of tube furnace, exhaust gas filter be set to heat preservation pipe plug and gas vent it
Between；
Exhaust gas filter includes import round tube, collecting pipe and outlet round tube.
One end of import round tube is open end, the other end is closed end, and open end is correspondingly connected with heat preservation pipe plug, and import
Round tube and outlet round tube and the cooperation of tubular type furnace cavity inner circle diameter dimension are consistent, and closed end is equipped with one group of uniformly distributed through-hole；
It is consistent with the structure of import round tube to export round tube, and is oppositely arranged；
Collecting pipe is the hollow pipe that one group of spiral winding extends back, to increase the contact area of gas and glass tube；
The quantity of hollow pipe and the number of openings of closed end are consistent, and one end of each hollow pipe is connected respectively import
The through-hole of round tube, the other end are connected respectively the through-hole of outlet round tube.
In the technical solution of the utility model, by an exhaust gas filter built in original tubular type furnace cavity tail end,
So that being respectively enterd in hollow pipe by the high-temperature gas being discharged in tube furnace by import round tube, condense in hollow pipe afterwards to the cold
On wall, to avoid particulate matter blocking gas vent by these particulate collections in hollow pipe.
Detailed description of the invention
Fig. 1 is a kind of collection filter device schematic diagram for tail gas end in high temperature process furnances of the utility model；
Fig. 2 is a kind of collection filter device top view for tail gas end in high temperature process furnances of the utility model.
Specific embodiment
For the utility model is more clearly understood, high-temperature tubular is used for one kind of the utility model with reference to the accompanying drawing
The collection filter device at tail gas end further illustrates in furnace, and specific embodiment described herein is only used for explaining that this is practical new
Type is not used to limit the utility model.
Referring to Fig. 1, a kind of collection filter device for tail gas end in high temperature process furnances, including tube furnace 1, tube furnace 1
Heat preservation pipe plug 8 is equipped in the tail end of cavity, 1 cavity tail end of tube furnace is connected with gas vent 2, it is characterised in that:
An exhaust gas filter built in the cavity tail end of tube furnace 1 is set between heat preservation pipe plug 8 and gas vent 2；
The exhaust gas filter includes import round tube 3, collecting pipe 4 and outlet round tube 5.
Referring to Fig. 1, Fig. 2, one end of import round tube 3 is open end 6, the other end is closed end 7, open end 6 and tube furnace 1
The heat preservation pipe plug 8 of cavity tail end is correspondingly connected with, and import round tube 3 and outlet 5 overall diameter of round tube and tubular type furnace cavity inner circle diameter
Dimensional fits are consistent, and closed end 7 is equipped with one group of uniformly distributed through-hole 7a；
The quantity of the through-hole 7a be set as six (or more)；
It is consistent with the structure of import round tube 3 to export round tube 5, and is oppositely arranged；
Collecting pipe 4 is the hollow pipe 4a that one group of spiral winding extends back, to increase the contact area of gas and glass tube；
The quantity of hollow pipe 4a is consistent with the through-hole 7a quantity of closed end 7, and one end of each hollow pipe 4a respectively corresponds
The through-hole 7a of import round tube 3 is connected, the other end is connected respectively the through-hole 7a of outlet round tube 5.
In the utility model, by an exhaust gas filter built in original tubular type furnace cavity tail end, so that by tubular type
By import round tube 3, via through holes 7a enters in hollow pipe 4a the high-temperature gas generated in 1 cavity of furnace respectively, condenses in sky afterwards to the cold
On heart pipe 4a inner wall, to avoid particulate matter blocking gas vent by these particulate collections in hollow pipe 4a.
