Abstract

The utility model discloses a domestic energy-saving boiler, wherein, the main structure of which is that a water jacket is arranged between a shell and an inner liner, the upper part of a hearth is provided with a water pipe communicated with the water jacket, and thermal insulation materials are arranged on the inner wall of the inner liner of the circumference of the hearth. A lateral direct-current plate is arranged in a smoke and fire chamber above the hearth, an S-shaped flue is formed by the direct-current plate in the smoke and fire chamber, and the direct-current plate is a water sandwich structure communicated with the water jacket. A coal feeding opening is arranged on the side wall of the hearth, the outside of the coal feeding opening is provided with a coal feeding box, wherein, the upper surface of which is provided with a cover of the coal feeding box, a ventilated box connected with the coal feeding box is arranged on the side face of the coal feeding box, a spillplate distributed with ventilation holes is arranged in the ventilated box, and a ventilation regulator is arranged on the outside of the spillplate. Because the length of the flue is increased by the utility model, the circumference of coal can not be cooled, and quantities of combustible gases can be volatilized by heating the coal in the coal feeding box, the utility model has the advantages of coal economization, complete combustion and little pollution.

Description

The domestic energy-saving boiler

Technical field

The utility model relates to a kind of boiler, relates in particular to a kind of domestic boiler.

Background technology

Existing domestic boiler generally comprises body of heater, water jacket, water inlet, delivery port, burner hearth and is arranged on the water pipe that the burner hearth top communicates with water jacket, its weak point is: (1) combustion flame is the straight line burning, directly enter atmosphere behind the water pipe of flue gas through the burner hearth top, flue gas is just shorter in the distance that boiler internal passes through like this, the flue dust that is discharged in the atmosphere is just bigger, and can not make full use of the heat of flue gas, waste resource; (2) be jacket structure for water around the burner hearth, so just easily cause coal cooling all around, temperature is lower during burning, and it is insufficient to burn, and volatilization is big, and is seriously polluted.

Summary of the invention

Purpose of the present invention is intended to overcome above-mentioned shortcoming, and a kind of flue is long, sufficient combustion can reduce the domestic energy-saving boiler that pollutes thereby provide.

For achieving the above object, the utility model adopts following solution: comprise shell, inner bag, burner hearth, water inlet, delivery port, coal filling hole, cleaning door, chimney, between shell and inner bag, be provided with water jacket, be provided with the water pipe that communicates with water jacket on the top of burner hearth, it is characterized in that: on the inwall of inner bag around the burner hearth, be provided with insulation material, above burner hearth, be provided with several horizontal direct current plates that keep at a certain distance away in the pyrotechnics chamber, the direct current plate constitutes S shape flue in the pyrotechnics chamber, the water interlayer structure of direct current plate for communicating with water jacket.

Above-mentioned domestic energy-saving boiler, it is characterized in that: described coal filling hole outside is provided with the coal bin that adds that is connected with coal filling hole, be provided with the coal case lid at the upper surface that adds coal bin, be provided with on the position parallel, coal bin side and add the ventilated box that coal bin is connected adding with coal filling hole, in ventilated box, be provided with spillplate, the some air vents of distribution are provided with damper on the spillplate outside spillplate.

Compared with prior art, the utlity model has following advantage:

1, because the utility model is provided with insulation material around burner hearth, just can keep higher temperature around the coal like this, coal is fully burnt, reduce volatilization, so the utility model can reduce pollution, the protection environment.

2, because the utility model is provided with the direct current plate that can constitute S shape flue in the pyrotechnics chamber, the water interlayer structure of direct current plate for communicating with water jacket, when flue gas passes through S shape flue in the process that moves upward like this, the heat that can make full use of in the flue gas heats the water in the direct current plate on the one hand, makes the intensification of boiler very fast; Flue gas can make the dust in the flue gas come off when running into the direct current plate on the other hand, thus the utlity model has economize on coal, flue dust is few, pollute little advantage.

3, because the utility model is provided with the coal bin that adds that is connected as a single entity with it in the outside of coal filling hole, when combustion flame temperature reaches 120 ℃-900 ℃, adding coal in the coal bin will be heated and volatilize a large amount of fuel gas, as carbon monoxide, so the utility model can make coal fully burn, pollute thereby reduce.
