Hot water boiler and water heating method

Abstract

The invention discloses a hot water boiler without flammable fuel, and relates to a water heating device. The hot water boiler comprises a base, a boiler body, a rotary shaft, a heating rotor, a bearing and a bearing gland, wherein the base is provided with the bearing; a water inlet cavity communicated with a water inlet and the interior of the boiler body is arranged among the boiler body, the bearing and the rotary shaft; a water decomposer is arranged in the water inlet cavity; the rotary shaft in the boiler body is provided with the heating rotor; the two end faces of the heating rotor are respectively provided with at least two heating rings at intervals; the heating rings are coaxial with hubs of the heating rotors and are not equal in diameter; the inner wall of the boiler body is provided with friction rings in inserted and embedded fit with the heating rings; a heating interval of 0.3-2.8 mm is formed between each friction ring and the corresponding heating ring; the side wall of the boiler body is provided with a water outlet. According to the hot water boiler, space is saved, management and maintenance are achieved without a lot of people, the heating speed and heating efficiency are high, energy sources are saved, cost for hot water processing is low, pollution to environment does not exist, maintenance is easy and convenient, and the hot water boiler is suitable for heating and processing hot water.

Description

technical field [0001] The invention relates to a water heating device, in detail, it is a space-saving hot water device that does not require multiple people to manage and maintain, has high heating speed, high efficiency, energy saving, low cost of hot water production, no pollution to the environment, and simple and convenient maintenance. Boilers and methods of heating water. Background technique [0002] We know that in the prior art, burning fuel is used to heat water, or electric heating elements are used to convert electric energy into heat energy. These two methods have slow heating speed of water, low energy conversion rate, large energy consumption, and the preparation of hot water high cost. Most of the boilers used to heat water use coal as fuel, and the use of coal to heat water has the following disadvantages: 1.

Problems solved by technology

[0002] We know that in the prior art, burning fuel is used to heat water, or electric heating elements are used to convert electric energy into heat energy. These two methods have slow heating speed of water, low energy conversion rate, large energy consumption, and the preparation of hot water high cost

Most of the boilers used to heat water use coal as fuel, and the use of coal to heat water has the following disadvantages: 1. Discharge a large amount of air-polluting gas, which is harmful to the environment and affects people's health. It is an increasingly serious fog in recent years. One of the main culprits of hazy weather; 2. The utilization rate of heat generated by coal combustion is low, wasting resources, and the cost of making hot water is high; 3. Large-scale coal-fired boilers occupy a large area and require multiple people to watch and maintain, which is time-consuming and laborious , high cost of use

A small amount of hot water boilers heated by other fuels also have the problem of polluting the air, and the cost of fuel is high, not economical and practical, and inconvenient to use

The device that uses electric heating elements to heat water has great safety hazards, many equipment failures, and a large amount of maintenance. The electric heating elements heat water slowly, with low efficiency, and the production cost of hot water is high, especially not suitable for large-scale heating equipment.
