Description

Technical Field

[0001] The utility model relates to the technical field of boilers, and in particular to a low-carbon and environmentally friendly boiler waste heat utilization device. Background Art

[0002] Low-carbon environmental protection refers to reducing the energy consumed in daily life, and its main purpose is to reduce the emission of greenhouse gases. The boiler is an energy conversion device. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's lives, and can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] However, the prior art still has its shortcomings. In the prior art, the boiler will produce too much heat, and most of the heat is used for heating the factory or heating the water in the water tank, and through the corresponding heat conduction, the purpose of heat utilization is achieved. However, while heating is convenient, the hot gas produced in the boiler waste heat will also carry incompletely burned solid particles, and the solid particles are easy to accumulate on the heating pipe, thereby affecting heat conduction.

[0004] Therefore, we propose a low-carbon and environmentally friendly boiler waste heat utilization device to solve this problem. Utility Model Content

[0011] Preferably, one end of the No. 2 connecting pipe is fixedly connected to an outer surface of one side of the mounting shell; and the No. 1 connecting pipe is fixedly connected to the exhaust port of the boiler via a flange.

[0012] In the utility model, the low-carbon and environmentally friendly boiler waste heat utilization device is provided with a No. 1 connecting pipe, a filter screen, a No. 2 connecting pipe, and a water tank. When the tail gas is processed, the tail gas will enter the installation shell through the No. 1 connecting pipe, and the tail gas will be filtered by the filter screen. The filtered tail gas will enter the No. 2 connecting pipe, and the water in the water tank will be heated by the tail gas in the No. 2 connecting pipe, so that the waste heat of the tail gas can be utilized. The setting of the filter screen can filter the particles in the tail gas, and can prevent the particles from adhering to the No. 2 connecting pipe. The particles will hinder the transfer of heat, thereby causing the waste heat of the tail gas to be unable to be utilized;

[0013] In the utility model, the low-carbon and environmentally friendly boiler waste heat utilization device is provided with a mounting shell, an inner frame, a fixing groove, a mounting plate, a sliding groove, a fixing block, a pushing block, a groove, a mounting block, a threaded groove, a spring, a mounting frame, a filter screen, a fixing screw, and a connecting block. When the filter screen is cleaned, the pushing block is pushed, and the movement of the pushing block drives the fixing block to leave the fixing groove. When the fixing block leaves the fixing groove, the mounting block leaves the inner frame under the action of the spring rebound. The movement of the mounting block drives the mounting plate to move, thereby driving the mounting frame to move, so that the filter screen leaves the mounting shell, which is convenient for cleaning the filter screen and improves efficiency.

[0014] The utility model has reasonable structural design, simple operation and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
