The invention discloses an automatic furnace door valve for a hydrochloric acid synthesis furnace. The automatic furnace door valve comprises a synthesis furnace main body, wherein a furnace door valve is arranged on the side wall of a furnace cylinder of the synthesis furnace main body; the furnace door valve comprises a pneumatic spherical shut-off valve, an explosion-proof solenoid valve, an air pressure reducing valve and a valve controller; the pneumatic spherical shut-off valve is mounted at a furnace door of the side wall of the furnace cylinder; instrument air passes through the air pressure reducing valve, then outputs and communicates with air from an air inlet of the explosion-proof solenoid valve; an air outlet of the explosion-proof solenoid valve communicates with a valve cavity of the pneumatic spherical shut-off valve; the valve cavity is internally provided with a piston with a gear on the inner side; the gear is meshed with the gear of a valve core; and the explosion-proof solenoid valve is connected with the valve controller. According to the invention, the furnace door valve is adopted to replace an artificial furnace door switch, thereby not only saving manpower, but also ensuring that personnel are not sprayed by flames, avoiding personal injury and improving safety and reliability.
Description
technical field [0001] The invention relates to a furnace door valve, in particular to an automatic furnace door valve used in a hydrochloric acid synthesis furnace. The invention belongs to the technical field of hydrochloric acid synthesis equipment. Background technique [0002] The hydrochloric acid synthesis furnace is composed of a combustion chamber, a combustion nozzle, a film absorption cooling tower and a recovery tower. The combustion chamber is a cylinder made of heat-resistant and impermeable graphite, with a steel shell on the outside, and cooling water between the two. The main part of the combustion nozzle is a transparent quartz sleeve, which is installed in the uppermost impermeable graphite frame of the combustion chamber. Generally, the inner pipe is passed through chlorine gas, and the outer pipe is passed through with hydrogen gas. The combustion method of upper ignition or lower ignition can be adopted. The film absorption cooling tower is a multi-tu...
