Description

Vertical boiler superheater supporting structure

Technical Field

The utility model relates to a waste incineration power generation field.

Background

Domestic waste incineration power plants basically adopt medium-temperature medium-pressure steam parameters, and consider that the main income of the incineration power plants is the income of power generation and internet surfing, so that the method and the system improve the parameters of power generation steam and the efficiency of waste incineration power generation.

The heating process of the working medium of the steam boiler can be divided into three stages of preheating water, evaporating water and superheating steam. As the steam pressure and temperature are increased, the heating surface of the superheater is greatly increased. The vertical boiler superheater is arranged in a 3 rd flue, and the support form of the superheater and the 3 rd channel is a difficult problem. The domestic common structure is a supporting structure, the clamping plate is adopted to connect the superheater and the 3 rd channel water-cooled wall, the field supporting and mounting space is small, the welding amount is large, and the operation is difficult.

Disclosure of Invention

The utility model aims to solve the technical problem that realize a convenient fixed, convenient over heater that detects supports, fixed knot constructs.

In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a vertical boiler superheater bearing structure is equipped with at least one superheater in the flue of vertical setting, every the superheater comprises the heating surface pipe that many levels were arranged, its characterized in that: and part of the heating surface pipe of each superheater extends out of the flue wall of the flue and is fixed on the flue wall.

The wall thickness of the heating surface pipe extending out of the flue is larger than that of the heating surface pipe not extending out of the flue.

And the heated surface pipe of each superheater extending out of the flue accounts for 25-40% of all the heated surface pipes.

And the heated surface pipe of each superheater extending out of the flue is a heated surface pipe positioned in the middle area of the superheater.

The flue of the fixed superheater is a third flue, a second flue is arranged beside the third flue, a radiation chamber is arranged above the second flue, an evaporator is arranged below the second flue, and flue gas passing through the second flue enters the third flue through the radiation chamber and the evaporator.

And three superheaters are arranged in the third flue and are respectively positioned at the upper part, the middle part and the bottom of the third flue.

The utility model has the advantages of it is fixed to utilize over heater self pipeline, has reduced fixed the degree of difficulty, has also reduced fixed cost, also makes things convenient for the sampling temperature measurement simultaneously.

Drawings

The following brief descriptions of the contents expressed by each figure and the marks in the figures in the specification of the present invention are as follows:

FIG. 1 is a schematic view of a vertical boiler superheater support structure;

the labels in the above figures are: 1. a radiation chamber; 2. an evaporator; 3. a superheater; 4. a third flue; 5. a heated face tube.

Detailed Description

The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.

The vertical boiler has a vertically arranged flue, wherein a third flue 4 and a second flue are arranged adjacently, the superheater 3 is fixed in the third flue 4, and generally three (groups of) superheaters 3 are fixed in the third flue 4 and are respectively positioned at the upper part, the middle part and the bottom part of the third flue 4. Every over heater 3's structure is the same, comprises the heating surface pipe 5 that the level set up, and every heating surface pipe 5 tip passes through the return bend and is connected with adjacent heating surface pipe 5 and constitutes the water service pipe who singly advances singly to go out jointly, and an over heater 3 constitutes a pipeline that supplies water to pass through heating surface pipe 5 promptly, and the top of second flue is equipped with radiation chamber 1, and the below is equipped with evaporimeter 2, and the flue gas that burns passes through the second flue passes through radiation chamber 1, evaporimeter 2 gets into third flue 4.

In order to fix the superheater 3 conveniently, part of the heated surface pipe 5 of each superheater 3 extends out of the flue wall of the flue and is fixed on the flue wall, namely, the whole superheater 3 is supported by the part of the extended heated surface pipe 5, and the superheater 3 is suspended and fixed in the third flue 4 by the heated surface pipe 5 fixed in the flue wall, so that the overheater 3 can be effectively supported and field-mounted on the difficult problem.

In order to improve the reliability of the support, the wall thickness of the heating surface pipe 5 extending out of the flue is larger than that of the heating surface pipe 5 not extending out of the flue. In order to improve the economy, the heated surface pipe 5 of each superheater 3 extending out of the flue accounts for 25-40% of the total heated surface pipes 5, and the heated surface pipe 5 of each superheater 3 extending out of the flue is the heated surface pipe 5 located in the middle area of the superheater 3, so that the support reliability can be ensured, and the heat loss caused by external heat dissipation can be reduced.

In addition, a temperature sensor can be fixed on one of the heated surface pipes 5 of each superheater 3, which extend out of the flue wall, and the sensor can be transmitted to detection equipment in a wired or wireless mode, so that the metal wall temperature of the superheater 3 can be detected, and effective data support is provided for preventing the wall temperature of the superheater 3 from being overtemperature.

The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
