Abstract

The patent discloses a liquid attack prevention boiler device, which comprises a steam bag, a boiler coil, a steam control valve and a drain valve; the boiler coil is arranged inside the steam pocket; a connecting pipeline and a valve are arranged between the steam pocket and the drain valve; steam enters the boiler coil in the steam pocket through the control valve, cold water in the steam pocket is indirectly heated through the outer wall of the boiler coil, and meanwhile, the steam is condensed into liquid water and returns to the steam pocket after passing through the drain valve. The boiler device can not only fully utilize the heat energy of the steam, but also avoid the phenomenon of liquid impact caused by the steam directly entering the steam drum and improve the boiler speed.

Description

Liquid attack prevention boiler device

Technical Field

The utility model discloses the technique relates to coal chemical industry field and chemical machinery manufacturing field specifically are a prevent liquid and hit boiling furnace device.

Background

In the chemical production process, desalted water is required to be used for carrying heat energy generated in the chemical reaction process out of the reactor, the desalted water is heated by the reactor to form a steam and water mixture, the steam and the water mixture enter a steam drum through a pipeline, the water and the steam are separated in the steam drum, the steam is sent out of the steam drum through the pipeline, and the separated water enters the reactor again. The reactor needs to be heated to normal production temperature by steam during the initial start-up and after overhaul, and the process of heating the reactor is called as a boiler. The medium used by the boiler is still desalted water, the desalted water in the steam packet is heated by steam through the boiler device, and the heated desalted water circulates between the reactor and the steam packet, so that the temperature of the reactor is gradually increased and meets the process requirement. The existing boiler devices mainly have two types: one is a start-up injector; the other is a tubular bubbling steam heater. Both of these boiler arrangements heat in a manner that steam enters the steam drum in direct contact therewith, thereby heating the water in the steam drum. Both of these boiler arrangements suffer from liquid slugging. The liquid impact phenomenon of the pipeline equipment is usually caused by that the gas phase and the liquid phase are converted in the pipeline, so that the fluid has instant vacuum degree in the pipeline, and the surrounding fluid impacts instantaneously, thereby generating huge impact sound, generally occurring in a steam system, and damaging the pipeline equipment in serious conditions.

SUMMERY OF THE UTILITY MODEL

The technical problem that this patent was solved provides a boiling furnace device is hit to liquid to solve the liquid that two kinds of boiling furnace methods exist in the above-mentioned background art and provide a boiling furnace device safe, high-efficient, easy and simple to handle.

The technical problem that this patent was solved adopts following technical scheme to realize: a boiling furnace device capable of preventing liquid attack comprises a steam bag, a boiling furnace coil, a steam control valve and a drain valve; the method is characterized in that: the boiler coil is arranged inside the steam pocket; a connecting pipeline and a valve are arranged among the steam packet, the steam control valve and the drain valve; and pressure, temperature and liquid level sensors are arranged in the steam drum. Steam enters a boiler coil in the steam bag through a steam control valve and a pipeline to indirectly heat desalted water in the steam bag, and the steam is condensed into condensate in the boiler coil. The condensate is discharged out of the boiler coil under the action of pressure and returns to the steam bag through a drain valve and a pipeline.

The beneficial effect of this patent: because the steam is not in direct contact with water, the liquid impact phenomenon can not be generated, the boiler boiling process can be safely and efficiently carried out, the boiler boiling speed is increased, and the damage of the liquid impact phenomenon to the equipment pipeline is avoided. The speed of the boiler can be controlled by controlling the opening of the steam control valve, and the operation is convenient and fast. The utilization rate of resources and energy resources is high, the whole boiler boiling process has no waste of energy resources, and heat energy and water resources of steam are all recycled into the steam bag.

In the figure: the steam boiler 1 comprises a steam bag, a boiler coil 2, a steam control valve 3 and a drain valve 4.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the efficacy of the patent easy to understand, the invention is further explained by combining with the specific figures.

Example (b): as shown in figure 1, the liquid attack prevention boiler device comprises a steam bag 1, a boiler coil 2, a steam control valve 3 and a drain valve 4; the method is characterized in that: the boiler coil 2 is arranged inside the steam pocket; a connecting pipeline and a valve are arranged between the steam pocket 1 and the steam control valve 3 and the drain valve 4; and pressure, temperature and liquid level sensors are arranged in the steam pocket 1.

This patent is to starting ejector and two kinds of boiling furnace modes of tubular tympanic bulla steam heater and has the problem of liquid impact phenomenon to propose the improvement measure, through using the boiling furnace coil pipe, changes the indirect heating into direct heating. As shown in the attached figure: steam enters a boiler coil in the steam bag through a steam control valve and a pipeline to indirectly heat desalted water in the steam bag, and the steam is condensed into condensate in the boiler coil. The condensate is discharged out of the boiler coil under the action of pressure and returns to the steam bag through a drain valve and a pipeline. As long as the steam pressure is higher than the pressure in the steam bag, the cooking process continues. By controlling the steam pressure, the temperature and pressure of the final boiler of the steam drum can be controlled.

Having thus shown and described the basic principles and principal features of this patent, together with the advantages thereof, it will be understood by those skilled in the art that the invention is not limited by the foregoing embodiments, which are merely illustrative of the principles of this patent, but is capable of numerous changes and modifications within the spirit and scope of this patent, as defined by the appended claims, along with their full scope of equivalents.
