Problems solved by technology

[0003] However, the current boiler waste heat recovery energy-saving and environmental protection equipment still has some shortcomings. When coal is burned, it will produce flue gas containing sulfur dioxide gas and slag. The existing equipment does not purify the slag in the flue gas produced by the boiler. , direct emission will cause air pollution, the second is that the sulfur dioxide gas in the flue gas produced by the boiler is not recycled, and the direct emission will easily form acid rain with the water vapor in the air, causing environmental pollution. The efficiency is not high, and the loss of energy consumption is large;

Embodiment 1

[0041] Such as Figure 1-Figure 5 As shown, an energy-saving and environment-friendly device with waste heat recovery function includes a combustion bin 1, an anti-scald casing 101 fixed on the top of the combustion bin 1 by bolts, a water tank 102 fixedly arranged in the anti-scald casing 101, a sliding set The side-by-side door 103 on the combustion chamber 1 side plate, the dust filter 104 fixedly arranged in the combustion chamber 1 and the dust collection box 105 with the upper opening on the bottom end of the combustion chamber 1 are slidably arranged, and the anti-scald housing 101 top is fixedly installed There are water inlet valve, water outlet valve, replenishment valve and pressure relief valve. The bottom end of the water outlet valve runs through the outer wall of the anti-scald housing 101 through a pipe and extends to the bottom. Open the water outlet valve to extract hot water, and the water inlet valve is used for water supply and replenishment The valve is u...

Embodiment 2

[0049] In Example 1, although the waste heat of the flue gas produced by coal combustion is used efficiently, at the same time, the sulfur dioxide in the flue gas is desulfurized to generate sulfur trioxide, and then sulfur trioxide and water generate sulfuric acid and then the sulfuric acid is utilized to improve the enterprise. benefit and protect the environment, but there are also deficiencies in it. When the coal is placed on the dust screen 104, the coal particles are of different sizes. The leaks of the dust leakage screen 104 fall into the dust box 105, resulting in a waste of resources;

[0050] Such as Figure 6-Figure 8 As shown, a kind of energy-saving and environment-friendly equipment with waste heat recovery function, a switch assembly 106 for preventing coal from falling is provided between the dust leakage screen 104 and the dust collection box 105, the switch assembly 106 includes a rotating rod 1061, fixedly sleeved on the rotating rod The first bevel gear ...

Embodiment 3

[0053] In embodiment 2, the relatively sliding slide plate 1066 is set to block the dust leakage screen 104, which solves the problem that the coal with smaller particles has directly fallen into the dust box 105, but when the slide plate 1066 blocks the dust leakage screen 104, the coal is still in the dust leakage screen 104. The accumulation at the hole may cause the leakage hole to be blocked, which is not conducive to the collection and recycling of dust;

[0054] Such as Figure 9 As shown, a kind of energy-saving and environment-friendly equipment with waste heat recovery function, a vibration assembly 1069 for shaking the dust leakage screen 104 is provided between the sliding plate 1066 and the dust leakage screen 104, and a vibration chute adapted to the vibration assembly 1069 is provided on the sliding plate 1066 The tremor assembly 1069 is used to vibrate the dust filter 104, so that the dust is shaken down on the dust filter 104. The tremor assembly 1069 includes...

Abstract

The invention discloses energy-saving and environment-friendly equipment with a waste heat recovery function, and relates to the technical field of energy-saving and environment-friendly equipment of boilers. Filter assemblies are symmetrically arranged in a combustion bin, each filter assembly comprises a fireproof frame and a filter screen, and an anti-scalding shell is provided with two sets of heating pipes, a first strip-shaped pipe and a second strip-shaped pipe; and an air suction fan, an adsorption device, a desulfurization device, a drying device and an exhaust fan are arranged at the outer side of the anti-scalding shell. According to the energy-saving and environment-friendly equipment, the filter assemblies, the heating pipe, the first strip-shaped pipe, the second strip-shaped pipe, the air suction fan, the adsorption device, the desulfurization device, the drying device, the exhaust fan, a third strip-shaped pipe and an air nozzle form circulation to form a waste heat recovery filter system, and the waste heat recovery filter system performs waste heat internal circulation, flue gas filtration adsorption and desulfurization treatment on flue gas, so that the waste heat using rate is improved, a generated sulfur trioxide solute is recycled, the industrial efficiency is improved, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly equipment for boilers, in particular to an energy-saving and environment-friendly equipment with waste heat recovery function and a use method. Background technique [0002] The waste heat recovery and reuse of traditional boilers is mainly reflected in the economizer. The economizer is a part of the boiler. It is sandwiched in the boiler flue and includes many curved pipes. There is water circulation in the pipes and high-temperature flue gas outside the pipes. , when the high-temperature flue gas passes through the pipeline, the heat exchange is completed, the water is heated up, the temperature of the flue gas will decrease, and the heated water will enter the boiler again, so that the temperature of the boiler feed water will increase, so as to achieve the purpose of saving coal. Simply put , The economizer is a device that uses the waste heat of the flue gas at ...
