Description
Technical field
The utility model belongs to a kind of tubular type heating equipment, and in particular to a kind of crude benzene tubular furnace.
Background technique
Tube furnace is the heating equipment of crude benzol distillation, is used to heat rich oil in crude benzol distillation, to carry out rectifying separation
Important equipment.Frequently with BF gas heating, tubular type furnace bottom is uniformly distributed along the circumference nozzles, and the inlet channel of nozzles is telescopic
Structure, inner cylinder are coke-stove gas channel, and outer cylinder is blast furnace gas channel.Wherein coke-stove gas nozzles play altar lamp and light height
The effect of producer gas guarantees that blast furnace gas nozzles do not extinguish, avoids the generation of gas explosion accident.Altar lamp uses coke-oven coal
Gas carries the substances such as tar, steam, naphthalene in coke-stove gas secretly, and after burning fire, impurity blocks stomata, and condensation vapor Cheng Shuihou,
Gas piping is sealed, causes coke-stove gas that can not pass through, causes to stop working, or even blow out.Existing tubular type drop-bottom heat preservation uses
Be that insulating brick is built by lower layer, surface layer smears heat resistance concrete.Due to start-stop tube furnace frequent in production process, opens steam and sweep vapour, furnace
Bottom insulating brick cracks under the action of expanding with heat and contract with cold with steam condensate (SC), and coal gas nozzles are all to be directly installed on bottom plate in addition
On, the insulating layer of nozzles channel and surrounding does not take the measure of separating, and nozzles channel aperture is smaller, leads to blast furnace gas nozzles
It is often flame-out, burn between the crack that coal gas seals in inside furnace bottom insulating layer, cause steel plate of furnace hearth temperature distortion, or even burn it is red, if
It handles not in time, just there is the danger for burning steel plate of furnace hearth, the security risks such as poisoning, explosion easily occur when using blast furnace gas
Problem.
Summary of the invention
The technical issues of the utility model is solved is to provide a kind of crude benzene tubular furnace, solves altar lamp and use coke-oven coal
Impurity, which blocks stomata and condensation vapor and lives gas piping at water seal, during gas causes coke-stove gas can not be by causing to stop working, put
The problems such as big gun；It solves the problems, such as that coal gas seals in furnace bottom insulating layer, eliminates and the peaces such as poisoning, explosion easily occur when using blast furnace gas
Full potential problem.Its structure is simple, has a safety feature, and maintenance and repair is convenient, has been solved perfectly in above-mentioned background technique and has occurred
The problem of.
The utility model uses following technical scheme to realize in order to solve the above problem:
A kind of crude benzene tubular furnace, including coke oven bridge tube lining brick is set on the inside of insulating layer on tubular type drop-bottom, it is formed vertical
Round kiln fire in a stove before fuel is added mouth, crude benzene tubular furnace bottom is uniformly distributed along the circumference furnace bottom nozzles；In altar lamp nozzles coke oven gas pipe bottom
Block clearing valve is set, it is convenient periodically to release coke-stove gas channel internal water accumulation and clean altar lamp nozzles.
Compared with prior art, the utility model has the beneficial effects that (1) is in altar lamp nozzles coke oven gas pipe bottom
Block clearing valve is set, and convenient periodically to release coke oven gas pipe internal water accumulation and clean altar lamp nozzles, altar lamp burning improves, do not put out
Fire；Coke-stove gas water amount is reduced, and tube furnace is swept the vapour time and substantially shortened, and the steam condensate (SC) generated when sweeping vapour is seldom.(2) exist
Setting coke oven bridge tube lining brick prevents furnace bottom insulating layer from skewered phenomenon occur and blowing out accident on the inside of insulating layer on tubular type drop-bottom, disappears
Except the security risks such as poisoning, explosion easily occur when using blast furnace gas, guarantee tube furnace flameholding, fire box temperature, richness
Oil temperature is improved, and keeps stable, reliable, is effectively guaranteed entire crude benzol production system stable operation.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: 1- tubular type drop-bottom, 2- blast furnace gas entrance, 3- coke-stove gas entrance, 4- insulating brick, 5- furnace bottom nozzles,
6- radiant tube, 7- bridge tube lining brick, 8- air intake, 9- altar lamp nozzles, 10- air intake, 11- block clearing valve.
Specific embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution of the utility model is specifically described.
Referring to attached drawing 1, a kind of crude benzene tubular furnace described in the utility model is included in the heat preservation of tubular type drop-bottom [1] above
Coke oven bridge tube lining brick [7] are set on the inside of brick [4], the coke oven bridge tube lining brick [7] vertically built forms round kiln fire in a stove before fuel is added mouth [5], furnace
The inlet channel of fire in a stove before fuel is added mouth [5] is telescoping structure, and blast furnace gas enters the blast furnace gas of outer cylinder by blast furnace gas entrance [2]
The air of pipeline, blast furnace gas and air intake [8] entrance is sufficiently mixed after-combustion；Crude benzene tubular furnace bottom is uniformly distributed along the circumference circle
Shape furnace bottom nozzles [5]；Coke-stove gas by coke-stove gas entrance [3] enter inner cylinder coke oven gas pipe, coke-stove gas with from
Air intake [10] enters the air mixing after-combustion of [6] in radiant tube, is formed altar lamp nozzles [9], altar lamp nozzles [9]
Play the role of altar lamp and light blast furnace gas, guarantees that furnace bottom nozzles [5] do not extinguish, in altar lamp nozzles [9] coke-stove gas
Block clearing valve [11] are arranged in duct bottom, convenient periodically to release coke oven gas pipe internal water accumulation and clean altar lamp nozzles [9].
Claims (3)
