Problems solved by technology

However, during the entire autoclaving maintenance stage of the autoclave, the amount of condensed water in the autoclave is very uneven. During the heating up stage of the autoclave, especially in the initial period, the temperature in the autoclave is lower than 100°C, and the amount of condensed water is very large. At this time , the steam pressure in the kettle is low, and the dynamic pressure and static pressure of the steam and condensed water in the thermodynamic steam trap are small, and the valve disc cannot discharge the condensed water in time due to the inability to move.
Furthermore, due to the large amount of condensed water and insufficient discharge area, it is impossible to discharge the condensed water in a timely and rapid manner; in addition, due to the relatively small volume of the sewage discharge tank, the debris accumulated inside needs to be discharged frequently. The manual sewage valve is installed in the sewage discharge tank. The lowest point of the tank is generally in the pit, so the operation is very difficult, and there is a danger of the operator being scalded by high-temperature steam, which poses a safety hazard

Embodiment Construction

[0021] The discharge method of the condensed water in the autoclave of the present invention, the temperature of the autoclave is raised to discharge in sections, and the temperature in the autoclave is ≤ 100 ° C, and the liquid level gauge installed between the lower part of the autoclave and the water collection box will detect The liquid level signal is sent to the controller, the controller according to whether the detected liquid level exceeds the set liquid level, when the detected liquid level exceeds the set liquid level, or the controller evaporates according to the set The interval time for discharge of condensed water in the autoclave, the interval output signal makes the pneumatic valve act, and the condensed water is removed at intervals. The invention controls the action of the actuator of the pneumatic valve through the controller to control the air source control valve. The actuator is opened or closed and installed in the water collection Pneumatic valve on hea...

Abstract

The invention relates to a method for discharging the condensation water of a still kettle, and the method belongs to the technical field of pressure containers. The still kettle is heated for temperature rise, when the temperature in the still kettle is equal to or lower than 100 DEG C, a controller outputs signals at intervals to open a pneumatic valve arranged on a header tank for discharging water according to the detected liquid level or the set discharge interval time of condensation water; when the temperature in the still kettle is larger than or equal to 100 DEG C, the controller output signals at intervals to open the pneumatic valve arranged on the header tank for discharging water according to the detected temperature difference between the upper and the lower parts of the kettle wall or the liquid level, at the same time, a thermal steam trap on a collecting pipe arranged between the bottom part of the still kettle and the header tank also discharges water. The method has the advantages that the condensation water of the still kettle can be completely and fast discharged; the use is safe and reliable; and the normal use of the still kettle can be ensured.

Description

technical field [0001] The invention relates to a method for discharging condensed water in an autoclave and a device thereof, belonging to the technical field of pressure vessels used in building materials, chemical industry, light industry, textiles and the like. Background technique [0002] Autoclave is a pressure vessel widely used in building materials, chemical industry, medicine, rubber and other industrial fields. According to the performance requirements of the product, the saturated steam is generally used as the heating medium, and it is placed in the kettle. Under the conditions of high temperature and high pressure, the product undergoes physical and chemical reactions to meet the expected requirements. In the autoclave curing process, based on the temperature, the product autoclave curing is divided into three stages: heating up, constant temperature and cooling down. Due to the heat exchange between the product and the saturated steam, a large amount of cond...
