Abstract
The utility model relates to a boiler flue heat-recovering device, and aims to solve the problem that the prior chimney of a boiler is not provided with a flue gas waste heat recovery device. The energy-saving boiler provided by the utility model has a casing and a chimney which are well below people's tolerance to heat when in use, and comprises a boiler body, a hearth, a boiler body water jacket, a chimney and a chimney water jacket. A communication water pipe is connected between the chimney water jacket and the boiler body water jacket; a water inlet pipe communicated with a chimney water cavity is arranged at the lower end of the chimney water jacket; and a water outlet pipe communicated with a boiler body water cavity is arranged at the upper end of the boiler body water jacket. When in use, cold water is injected from the water inlet pipe to the chimney water inflow water cavity in the chimney water jacket, when flue gas flows through the chimney, the residual heat in the flue gas has high temperature, the residual heat enters into the cold water through heat transmission, the cold water absorbs the heat and enters into the boiler body water cavity of the boiler body water jacket through the communication water pipe, flames in the hearth further heat the water in the boiler body water jacket to reach a higher temperature, and at last the water with high temperature flows out from the water outlet pipe.
Description
Technical field
The utility model relates to the boiler flue waste-heat recovery device.
Background technology
Existing boiler is in combustion process, and flue gas passes through from chimney, does not have flue gas waste heat recovery apparatus on the chimney, can not effectively utilize fume afterheat, causes the waste of the energy.
The utility model content
The purpose of this utility model provides a kind of boiler with the chimney waste-heat recovery device, for there not being the problem of flue gas waste heat recovery apparatus on the chimney that solves existing boiler, and the power economized boiler that the utility model provides shell and chimney can not scald, its embodiment is as follows:
The power economized boiler that shell and chimney can not scald comprises shaft, Lu Tang, and is connected with the stove pool and is positioned at the chimney of shaft top, and its concrete structure is as follows:
On chimney jambs, chimney water sleeve is installed, chimney water sleeve has heat-insulation layer outward, the chimney water cavity that has water-filling to use between chimney water sleeve and the chimney;
On the shaft sidewall, the shaft water jacket is installed, the shaft water jacket has heat-insulation layer outward, the shaft water cavity that has water-filling to use between shaft water jacket and the shaft;
Be connected with between chimney water sleeve and the shaft water jacket and be communicated with water pipe, be communicated with water pipe and be connected with chimney water cavity and shaft water cavity respectively.
The chimney water sleeve lower end is provided with the water inlet pipe that is connected with the chimney water cavity, and shaft water jacket upper end is provided with the outlet pipe that is connected with the shaft water cavity.
This boiler in use, pour into cold water by the chimney water inlet water cavity of water inlet pipe in chimney water sleeve, when flue gas is flowed through chimney, waste heat supply temperature in the flue gas is higher, the waste heat heat enters in the cold water by the heat conduction, cold water absorbs behind the heat by being communicated with water pipe and enters shaft water cavity in the shaft water jacket, and the flame in the stove pool further is heated to high temperature to the water in the shaft water jacket, and final high temperature water flows out from drainpipe.
As further improvement of the utility model, also be provided with circulation pipe, vent at middle part, the stove pool, circulation pipe can quicken the conduction of water temperature; The Lu Tang lower end also is provided with the dedusting door, trembles grey device and fire bars; Water inlet pipe is connected with water tank; Shaft water jacket lower end also is provided with Butterworth Hatch, hand hole, and the effect of Butterworth Hatch is to be convenient to clean the dirt of concentrating in the insulation water jacket; The delivery port place was provided with thermometer on safety valve, pressure self-unloading outlet also were installed on the shaft water jacket, so that the temperature of monitoring water also is equipped with the water level meter that is connected with water jacket in the shaft jacket sidewall, so that observe the water level in the insulation water jacket.
