Abstract
The invention belongs to the technical field of coke oven crude gas treatment, in particular a crude gas ignition method of coke oven diffusing tubes and a device thereof. A steel tube is erected on the outer side of each diffusing tube of a coke oven in the same direction, the tops of the steel tubes are bent to the ports of the diffusing tubes, and the horizontal sections of the steel tubes are provided with one valve; an air inlet is arranged on the vertical section of the steel tube and is enclosed by an air door made of a steel board; the front end of the valve on the horizontal section of the steel tubes is filled with coke oven crude gas for heating the coke oven; the valves on the steel tubes are opened, the coke oven crude gas is ignited by a tinder at the air inlet, the burning flame rises to the tops of the steel tubes and spouts to the ports of the crude gas diffusing tubes; crude gas diffusing valves are opened, and then the crude gas is diffused to be ignited for burning. The invention greatly improves the safety of special operation of the crude gas diffusion of the coke oven, reduces the labor intensity, enhances the timeliness, greatly reduces the pollutant emission and has the advantages of simple operation, practicality, convenient maintenance and low investment cost.
Description
Technical field
The invention belongs to the coal oven dithio-gas processing technology field, a kind of specifically coke oven emission pipe crude gas ignition method and device thereof.
Background technology
In coke-oven plant's coke oven was produced, owing to reasons such as fault, scheduled overhauls, the raw coke oven gas exhaust stack need carry out a large amount of coal oven dithio-gas and diffuses on the coke oven collecting main.Because raw coke oven gas directly enters in the atmosphere, can cause great environmental pollution, in order to reduce corresponding pollution, need ignition to handle, the most of harmful substance in the raw coke oven gas is burnt as far as possible.Conventional method adopts the 5m height manually to light a fire sparking mode is diffused igniting, because the working site environment is special, used torch is not only long but also heavy, and labour intensity is big during operation, and is absolutely unsafe, and is ageing also very poor.Adopt and diffuse igniter automatically, investment is big, and an exhaust stack is wanted more than 400,000 yuan, and long-term dependability is poor, and regular maintenance requires high.
Summary of the invention
Technical problem to be solved by this invention is: at the shortcoming of above prior art existence, the heat buoyancy principle of utilizing thermal current to rise, and fuel gas buring theory, a kind of coke oven emission pipe crude gas ignition method and device thereof are proposed, can greatly improve the security that coal oven dithio-gas diffuses special operational, reduce labor intensity, improve ageing.
The technical scheme that the present invention solves above technical problem is:
Coke oven emission pipe crude gas ignition method may further comprise the steps:
(1) in each exhaust stack outside of coke oven, set up a L shape steel tube in the same way, steel pipe top bends towards diffuses the mouth of pipe, adorns a valve at the steel pipe horizontal segment;
(2) open a slot on the steel pipe vertical section, an air inlet as fire hole and start-up burner encloses an air door at air port external application steel plate;
(3) termination coke oven heating coke-stove gas before the steel pipe horizontal segment valve;
(4) open valve on the steel pipe, full trrottle, light coke-stove gas with kindling material at the place, air port, coke-stove gas is lighted suitably damper aperture of back, with the smooth combustion in steel pipe of control coke-stove gas, combustion flame rises to the top in steel pipe under the effect of heat buoyancy, and spray to raw coke oven gas and diffuse the mouth of pipe;
(5) open raw coke oven gas and diffuse valve, diffuse raw coke oven gas and just lighted and burn.
Coke oven emission pipe raw coke oven gas point apparatus, by be located in the same way L shape steel tube of the exhaust stack outside, be located at steel pipe horizontal segment dress valve, be located at the air port of steel pipe vertical section and the air door that is located on the air port is formed, the top of steel pipe bends towards diffuses the mouth of pipe, termination coke oven heating coke-stove gas before the steel pipe horizontal segment valve.
Advantage of the present invention is: the present invention has improved coal oven dithio-gas greatly and has diffused the security of special operational, and has alleviated labour intensity, has improved ageingly, has greatly reduced the discharging of pollutant, and simple to operate, practical, easy to maintenance, investment cost seldom.
Description of drawings
Fig. 1 is the structural representation of apparatus of the present invention.
The specific embodiment
Embodiment one
The structure of coke oven emission pipe raw coke oven gas point apparatus of the present invention as shown in Figure 1, by be located in the same way L shape steel tube 1 of exhaust stack 5 outsides, be located at steel pipe horizontal segment dress valve 4, be located at the air port 3 of steel pipe vertical section and the air door 2 that is located on the air port is formed, the top of steel pipe 1 bends towards the mouth of pipe of exhaust stack 5, termination coke oven heating coke-stove gas before the steel pipe 1 horizontal segment valve 4.Weld the leader on the air door 2, air door 2 can be slided up and down, to regulate intake.Air port 3 is a slot (120mm * 10mm) as a fire hole of this device and an air inlet of start-up burner.
Coke oven emission pipe crude gas ignition method of the present invention carries out according to the following steps:
In each exhaust stack outside of coke oven, set up a L shape steel tube in the same way, steel pipe top bends towards diffuses the mouth of pipe, adorns a valve at the steel pipe horizontal segment;
(120mm * 10mm), an air inlet as fire hole and start-up burner encloses an air door at air port external application steel plate, welds the leader on the air door, and air door can be slided up and down, to regulate intake to open a slot on the steel pipe vertical section;
Termination coke oven heating coke-stove gas before the steel pipe horizontal segment valve;
When the coke oven emission pipe need be lighted a fire, open the valve on the steel pipe, full trrottle is lighted coke-stove gas with kindling material at the place, air port, and kindling material is preferably selected domestic electronic formula igniter for use, with anti-backfire burn point firer hand, coke-stove gas is lighted suitably damper aperture of back, and with the smooth combustion in steel pipe of control coke-stove gas, combustion flame is under the effect of heat buoyancy, in steel pipe, rise to the top, and spray to raw coke oven gas and diffuse the mouth of pipe;
