Description
Technical Field
The utility model relates to a chemical industry detection device technical field, especially a hydrochloric acid synthetic furnace end temperature automatic monitoring alarm system.
Background
The hydrochloric acid synthetic furnace is an important device of chlor-alkali production enterprises, and in the operation process, the temperature fluctuation of the lamp head of the hydrochloric acid synthetic furnace is large due to reasons of unsmooth airflow caused by lamp head scaling, overhigh hydrogen content in chlorine caused by abnormal production and the like, the lamp head is often cracked and damaged, the lamp head of the synthetic furnace is frequently damaged, a hydrogen pipeline near the lamp head leaks and catches fire, the temperature of a furnace end can be rapidly increased, the operation condition of the lamp head of the synthetic furnace can not be predicted in advance, and can cause the potential safety hazards of hydrogen chloride overflow, chlorine exposure and hydrogen exposure ignition, not only directly influence the quality of the hydrochloric acid, but also causes the production fluctuation of the whole chlor-alkali system, and even causes the serious production accident of the explosion of the chloroethylene generator when the production is serious, in addition, the quartz lamp tube is expensive in manufacturing cost, frequent damage can increase maintenance cost, production cost is increased, and production benefit is affected.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a hydrochloric acid synthetic furnace end temperature automatic monitoring alarm system. By using the device, if the temperature rises rapidly, DCS can alarm to remind field personnel to check whether the hydrochloric acid synthesis furnace has problems or not, the lamp holder is prevented from being cracked and damaged, the hydrogen chloride is prevented from overflowing, the chlorine is exposed and the hydrogen is exposed to catch fire, the accident rate is effectively reduced, and meanwhile, the device is simple in structure, safe and reliable.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a hydrochloric acid synthetic furnace end temperature automatic monitoring alarm system, includes a furnace end body, and furnace end body bottom is provided with hydrogen import b, and the top is provided with the hydrogen chloride export, and furnace end body side is provided with hydrogen import a and chlorine import from top to bottom, and the position that is close to the hydrogen chloride export on chlorine import upper portion sets up non-contact temperature sensor, non-contact temperature sensor electric connection to operation station.
The non-contact temperature sensor of the automatic monitoring and alarming system for the furnace end temperature of the hydrochloric acid synthetic furnace is a wall-mounted temperature sensing monitor.
Hydrochloric acid synthetic furnace end temperature automatic monitoring alarm system, its non-contact temperature sensor is magnetic temperature sensor, can paste to furnace end department convenient operation, the temperature is about the room temperature when normal use, if the lamp holder scale deposit makes the air current unsmooth, the production is unusual and causes the temperature fluctuation big in the too high reason such as hydrogen content in the chlorine, the lamp holder fracture often can appear, the damage, cause the synthetic furnace lamp head to frequently damage, the hydrogen pipeline leakage near the lamp holder catches fire, the furnace end temperature can rise fast, DCS can appear the too fast early warning suggestion of temperature rise, site personnel can go the scene further observation, judge whether emergency stop, handle the further expansion of prevention accident with the stove in advance, the lower early warning direct safety of cost. .
The temperature of the burner of the hydrochloric acid synthesis furnace is automatically monitored and alarmed, and the operation station of the automatic monitoring and alarming system is provided with a temperature monitoring and alarming system. At present, the safety requirement on personnel is higher and higher, the site does not allow the operating personnel to stay for a long time, only the site inspection and central control personnel watch the site monitoring every hour, but the position of the furnace end is lower, the monitoring cannot be carried out in all directions, and the temperature of the furnace end can be automatically monitored in all directions to monitor the change of the furnace end.
The automatic monitoring and alarming system for the temperature of the furnace end of the hydrochloric acid synthesis furnace is characterized in that a non-contact temperature sensor of the automatic monitoring and alarming system is connected with a furnace end body in an adhesion manner.
Compared with the prior art, the utility model provides a hydrochloric acid synthetic furnace end temperature automatic monitoring alarm system. By using the device, if the temperature rises rapidly, DCS can alarm to remind field personnel to check whether the hydrochloric acid synthesis furnace has problems or not, the lamp holder is prevented from being broken and damaged, the hydrogen chloride is prevented from overflowing, the chlorine is exposed and the hydrogen is exposed to be ignited, the accident rate is effectively reduced, the maintenance cost is reduced, the production cost is reduced, the stable operation of the whole production system is guaranteed, and meanwhile, the automatic temperature monitoring and alarming system is simple in structure, safe and reliable.
