Description
Technical Field
The utility model relates to a high-voltage electrode formula boiler especially relates to a bottom sprag device of high-voltage electrode formula boiler, and mainly used alleviates and reduces high-voltage electrode formula boiler normal operating in-process because the bubble appears in the circulating water decline process in the boiler inner tube and breaks and the gas that produces, belongs to industrial boiler technical field.
Background
The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy.
The high-voltage electrode boiler is a new type of industrial boiler equipment for steam supply and heating, and adopts the mode that the electrode bar is contacted with water containing a certain conductivity to let current pass through and directly heat water, so that compared with the traditional coal-fired and gas-fired boilers, the high-voltage electrode boiler has the advantages of high efficiency and environmental protection. With the increasing environmental protection requirement and the reduction of fuel gas reserves, the application range of the high-pressure electrode boiler is increasing under the conditions of abundant electric quantity and policy support.
In the operation process of the high-voltage electrode type boiler, the circulating water in the inner cylinder of the boiler directly collides with the wall of the inner cylinder of the boiler to generate gas in the descending process, so that the pressure in the inner cylinder of the boiler system is reduced, and therefore, a large amount of nitrogen is required to be filled to maintain the pressure in the boiler system.
Compared with the prior art in the high-pressure electrode type boiler, the arrangement of the bottom supporting device plays an important role in effectively reducing the generation of gas in the descending process of circulating water in the boiler inner cylinder and reducing the use amount of nitrogen for maintaining pressure in a boiler system.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bottom sprag device easy to detach, easy change for the above-mentioned requirement of fully provided, the device is fixed on the circulation inlet channel of boiler inner tube bottom. The device can effectively reduce the gas generated in the descending process of the circulating water in the boiler inner cylinder, thereby reducing the use amount of the nitrogen for maintaining the pressure in the boiler system.
The purpose of the utility model is realized like this: the bottom supporting device of the high-voltage electrode type boiler is characterized by comprising a pipe clamp (1), a connecting plate (2), a supporting baffle plate (3), a bolt (4) and a nut (5). The two ends of the connecting plate (2) are respectively welded with the supporting baffle (3) and the pipe clamp (1), the pipe clamp (1) is provided with three to five positions, is fixed on a circulating water inlet pipeline at the lower part of the boiler inner cylinder through bolts (4) and nuts (5), and is uniformly distributed on the circumference of the boiler inner cylinder. Each pipe clamp (1) is connected with a connecting plate (2) and upwards connected with a supporting baffle (3), the supporting baffle (3) is horizontal and circular or in other shapes, and a plurality of supporting points are arranged on the supporting baffle and are respectively connected with the upper end of the connecting plate (2).
The pipe clamp and the supporting plate are detachable structures; the bottom support device is arranged at the bottom of the inner cylinder of the high-voltage electrode type boiler.
The utility model discloses a bottom sprag device of high-voltage electrode formula boiler, mainly used alleviate and reduce high-voltage electrode formula boiler normal operating in-process because the bubble appears in the boiler inner tube well circulating water decline process and breaks and the gas that produces to can reduce the nitrogen gas use amount of holding pressure in the boiler system.
The principle of the utility model is as follows: the bottom supporting device is formed by fastening and connecting the pipe clamp, the connecting plate and the supporting baffle and is fixed on a circulating water inlet pipeline at the bottom of the boiler inner cylinder. Boiler water circulation refers to the circulation flow of a mixture of water and steam in an evaporation heating surface of a boiler, normal water circulation can ensure timely and reliable heat exchange of the evaporation heating surface of the boiler, and the boiler water circulation is one of basic conditions for safe operation of the boiler. In the actual operation of the boiler, circulating water in the inner cylinder of the boiler continuously drops, the circulating water directly impacts an end socket at the bottom of the inner cylinder of the boiler in the dropping process, and bubbles formed by the falling circulating water are largely broken due to the influence of gravity, so that a large amount of gas is generated, and pressure loss or overpressure in the inner cylinder of the boiler is directly caused. The bottom supporting device is arranged, and direct impact between circulating water and a bottom end socket of the inner cylinder of the boiler is reduced by shortening the descending stroke of the circulating water, so that the purpose of relieving the risk of pressure loss or overpressure of the inner cylinder of the boiler caused by gas formed by bubble breakage generated in the descending process of the circulating water is achieved, and the use amount of nitrogen for maintaining pressure in a boiler system is reduced. The round or other shape supporting baffle (3) plays a role of blocking when the circulating water descends.
The utility model has the advantages that: compared with the prior art, through the utility model discloses an above-mentioned design alleviates and reduces high voltage electrode formula boiler normal operating in-process because the boiler inner tube mesocycle water descends the process bubble and breaks and the gas that produces to the nitrogen gas use amount of holding pressure in the reduction boiler system. Meanwhile, in the use and maintenance process, the device also has the advantages of being easy to disassemble and replace.
