Water resistance industrial boiler

Abstract

A water resistance industrial boiler comprises a boiler main body and a water resistance heat energy generator. The bottom of a boiler shell is provided with a working liquid input port, the top of the boiler shell is provided with a working liquid output port, and the water resistance heat energy generator is arranged in the boiler shell. The water resistance heat energy generator is used for heating working liquid, the water resistance heat energy generator directly performs convection heat exchange with the working liquid medium, the heat exchange coefficient is high, and the heat efficiency is high. Meanwhile, the water resistance heat energy generator is arranged inside the boiler shell and does not generate pollutants and noise when working.

Description

Technical field [0001] The invention belongs to the technical field of boiler equipment, and specifically relates to water resistance industrial boilers. Background technique [0002] Industrial boilers occupy an important position in my country's production and life and are an important thermal power equipment. At present, in my country's industrial production, the light textile industry, energy industry, building materials, construction industry, chemical industry, metallurgical industry, transportation industry and military industry sector are sectors that consume a large amount of heat and will remain the main market for industrial boilers. [0003] Existing traditional boilers mainly have the following problems: [0004] First of all, coal-fired and oil-fired boilers can easily cause serious pollution to the environment. With the continuous changes in the energy supply structure and the increasingly stringent national energy conservation and environmental protection re...

AI Technical Summary

Problems solved by technology

[0004] First of all, coal-fired and oil-fired boilers are likely to cause serious pollution to the environment. With the continuous change of energy supply structure and the increasingly stringent national energy conservation and environmental protection requirements, their application scope will be more strictly restricted.

[0005] Second, gas-fired boilers are limited in scope of use due to the relative shortage of natural gas in China and the high cost of opening.

[0006] Third, resistance (electric heating tube) type and electromagnetic induction boilers have different degrees of problems in operation stability and safety due to the influence of electrical components by high temperature, especially resistance (electric heating tube) type, there are resistance heating components. High temperature oxidation, short service life, great risk of explosion and leakage

[0007] Fourth, electrode boilers are difficult to be widely used due to factors such as high production costs, complex operations, poor operational stability, and high safety control requirements.

The main problems are as follows: (1) The jet-type electrode-type electric boiler is easy to produce hydrogen, which is dangerous to a certain extent and may explode; (2) The use of low-voltage technology has high power costs, the boiler body is fragile, and the product is not mature enough. In the small-area heating field, the scope of application is narrow; (3) The structure of the submerged high-voltage electrode boiler is complex, and the boiler needs to continuously supply pure water and dosing during operation, the operation is complicated, and the operation stability is poor; (4) The existing jet-type electrode boiler and submerged high-voltage electrode boilers have complex design structures and cumbersome operations; (5) high production costs and narrow market application areas are difficult to obtain wide application
