Embodiment 1

[0028] An automatic non-condensable steam discharge device for evaporators used in the production of sodium sulfate, comprising exhaust covers arranged on the outer walls of several exhaust seats of the evaporator, the outer edges of the exhaust covers are also sleeved with exhaust sleeves, the An exhaust hole is opened on the exhaust sleeve, and the exhaust hole is connected with an exhaust pipe. A number of fixed seats are arranged on the inner walls of both sides of the exhaust seat, and a number of springs are also arranged. The upper ends of the springs are sleeved On the fixed seat, the lower end of the spring is connected with a connecting plate, the middle part of the upper surface of the connecting plate is connected with a connecting rod, the other end of the connecting rod is connected with the lower wall of the exhaust cover, and an electric motor is arranged above the exhaust cover. Pull rod, the output end of the electric pull rod is connected to the upper wall of...

Embodiment 2

[0031]On the basis of Embodiment 1, a sealing ring is installed on the contact surface between the exhaust cover and the exhaust sleeve. Through this setting, when non-condensable gas is not discharged, a good seal between the exhaust cover and the exhaust sleeve is ensured.

Embodiment 3

[0033] On the basis of the above embodiments, a vacuum pump is installed on the exhaust pipe. This setting facilitates quick discharge of non-condensable steam.

Abstract

The invention discloses an automatic non-condensable gas discharging device of an evaporator for producing anhydrous sodium sulphate, belongs to the technical field of anhydrous sodium sulphate production, and aims to solve the problem that non-condensable gas discharging of an existing evaporator is uncontrollable. The device comprises exhaust covers arranged on the outer walls of a plurality of exhaust seats of an evaporator, the outer edges of the exhaust covers are further sleeved with exhaust sleeves, and exhaust holes are formed in the exhaust sleeves and communicated with exhaust pipes. A plurality of fixing seats are on the inner walls of the two sides of the exhaust seats, a plurality of springs are arranged, and the fixing seats are sleeved with the upper ends of the springs. The lower ends of the springs are connected with a connecting plate, the middle of the upper surface of the connecting plate is connected with a connecting rod, and the other end of the connecting rod is connected with the lower walls of the exhaust covers. An electric pull rod is arranged above the exhaust covers, and the output end of the electric pull rod is connected with the upper walls of the exhaust covers. A gas sensor is installed on the lower surface of the connecting plate. A PLC is further arranged, and the electric pull rod and the gas sensor are electrically connected with the PLC. The scheme is suitable for an automatic non-condensable gas discharging device of an evaporator for producing anhydrous sodium sulphate.

Description

technical field [0001] The invention belongs to the technical field of sodium sulfate production, and in particular relates to an automatic non-condensable steam discharge device for an evaporator used in the production of sodium carbonate. Background technique [0002] my country has abundant glauberite resources, which are widely distributed in Sichuan, Yunnan, Hunan, Guangxi and other places. Glauber's salt (Na 2 SO4·CaSO 4 ) is mainly used in the production of Yuanmingfen (Na 2 SO 4 ). Anhydrous sodium sulfate, also known as Yuanming powder, is widely used in industry. At present, in the production process of Yuanming powder, non-condensable gas will be generated in the evaporator, which is a collection of inert gases. When the content of non-condensable gas in the evaporator is too high, it will seriously affect the evaporation effect, and it needs to be discharged. However, if too much non-condensable gas is discharged, a large amount of heat will be lost, which...
