Description
Technical Field
The utility model relates to a fire burning furnace fire observation hole on-line cleaner belongs to system sulphur production technical field.
Background
The sulfur production furnace and the tail gas furnace in sulfur production are both provided with the observation hole and the flame detector, so that the combustion condition in the hearth can be directly observed and monitored, the main measure for judging whether the air distribution quantity is proper is provided, and the function in the process of starting and stopping work is particularly important. The observation hole is blocked by sundries such as damaged lining or sulfur powder and the like, the combustion condition in the observation furnace can be influenced, if the flame detector observation hole is blocked, the flame detection signal can be influenced, the device is interlocked and stopped, and the safety risk of the device is increased. The sulfur production furnace is the pressure-fired, and inside high temperature combustion reaction that takes place has noxious gases such as hydrogen sulfide, sulfur dioxide simultaneously, directly opens sight glass ball valve clearance debris and can lead to inside flame and noxious gas to scurry out, has very big danger, so can only handle when the maintenance of shutting down.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a fire burning furnace heating furnace hole of seeing online clearance ware connects the flange before the hole of seeing ball valve, can accomplish the processing to the downthehole debris of seeing the fire under the prerequisite of guaranteeing device normal production operation and operating personnel self safety.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an online cleaner for a combustion furnace fire hole comprises a sleeve, a flange type tight part and a cleaning push rod, wherein the head end of the sleeve is fixedly connected with the flange type tight part, and the cleaning push rod is sleeved in the sleeve; the cleaning push rod comprises a cleaning head and an operating rod, the cleaning head penetrates through the flange type tightening piece, and the operating rod extends out of the tail end of the sleeve.
Furthermore, the head end of the cleaning push rod is of a conical structure.
Furthermore, a nitrogen inflow port is formed in the sleeve, a nitrogen outflow port is formed in the flange type tightening piece, and the nitrogen outflow port is communicated with the interior of the combustion furnace body.
Furthermore, the sleeve is made of stainless steel.
Furthermore, the cleaner also comprises a sealing plug, and the sealing plug is filled in a gap between the cleaning push rod and the tail end of the sleeve.
Furthermore, the sealing plug is made of graphite. Compared with the prior art, the beneficial effects of the utility model are that:
the utility model has simple structure, easy operation, no need of shutdown and maintenance during use, on-line cleaning of the fire observation hole and saving of shutdown and maintenance cost; the cleaning process is nitrogen-sealed, and the life safety of workers is guaranteed.
Drawings
FIG. 1 is a schematic structural view of an on-line cleaning device for a fire hole of a heating furnace of the present invention;
fig. 2 is a schematic view of a local structure of the present invention.
Wherein: 1. cleaning the head; 2. a flange-type fastener; 3. a nitrogen gas inlet; 4. a sleeve; 5. a sealing plug; 6. an operating lever; 7. and a nitrogen gas outflow port.
Detailed Description
The following non-limiting examples will allow one of ordinary skill in the art to more fully understand the present invention, but do not limit the invention in any way.
An online cleaning device for a heating furnace observation hole is structurally shown in figures 1-2 and comprises a sleeve 4, a flange type tight part 2 and a cleaning push rod, wherein the sleeve is made of stainless steel, the head end of the sleeve 4 is fixedly connected with the flange type tight part 2 in a welding mode, and the flange type tight part 2 is matched with the flange of the observation hole in specification; the cleaning push rod is sleeved in the sleeve 4; the cleaning push rod comprises a cleaning head 1 and an operating rod 6, the cleaning head 1 is of a conical structure and is prevented from being clamped by a combustion furnace body lining during drawing, the cleaning head 1 penetrates through the flange type tightening piece 2, the operating rod 6 extends out of the tail end of the sleeve 4, and impurities are pushed into the combustion furnace body by pushing and pulling the operating rod 6; a nitrogen flow inlet 3 is formed in the sleeve 4, a nitrogen flow outlet 7 is formed in the flange type compact piece 2, the nitrogen flow outlet 7 is communicated with the interior of the combustion furnace body, nitrogen enters the sleeve through the nitrogen flow inlet 3 and enters the interior of the combustion furnace body through the nitrogen flow outlet 7 in the flange type compact piece 2; a sealing plug 5 is filled in a gap between the operating rod 6 and the tail end of the sleeve 4, and the sealing plug 5 is made of graphite.
The use method of the online cleaning device for the observation hole of the heating furnace comprises the following steps:
when the fire observation hole is cleaned, the combustion furnace sight glass ball valve is closed, the sight glass is detached, and the flange type compact piece 2 of the cleaner is connected and fastened with the combustion furnace sight glass flange; introducing nitrogen, wherein the nitrogen enters the sleeve 4 through the nitrogen flow inlet 3 and enters the combustion furnace through the nitrogen flow outlet 7 to prevent flame from reversely crossing; opening the sight glass ball valve, slowly pushing the operating rod 6 downwards, pushing the blocking impurities into the combustion furnace body through the cleaning head 1, and allowing the impurities to enter the combustion furnace and undergo pyrolysis; and (5) after cleaning, pulling the operating rod 6, taking out the cleaning head 1, closing the sight glass ball valve and stopping introducing nitrogen.
