DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1-5:

[0020] Referring to the accompanying drawings: In this embodiment, an energy-saving and environmentally friendly coal-fired hot water boiler with a built-in cross heat exchanger includes an outer shell 1 and a cross heat exchanger 4. The upper inner wall of the outer shell 1 is fixedly connected to the outer wall of the cross heat exchanger 4. How to operate and use the cross heat exchanger 4 has been realized in the technology, and no further explanation is given. The model is selected according to usage requirements. The outer wall pipe of the cross heat exchanger 4 is connected to the outer wall of the outer shell 1. The top of the outer shell 1 is connected to a protective structure 2, the front of the outer shell 1 is connected to an opening and closing structure 3, and a box body 5 is inserted at the bottom of the front of the outer shell 1. The left and right sides of the front of the box body 5 are respectively fixed with second handles 6, and the second handles 6 are convenient for pulling the box body 5 to move.

[0021] The protective structure 2 includes a grid 201 and an adsorption plate 202. The bottom of the grid 201 is fixedly connected to the top opening of the shell 1. The inner wall of the grid 201 is plugged into the outer wall of the adsorption plate 202. The adsorption plate 202 is an activated carbon grid. The front of the adsorption plate 202 is fixedly connected to a horizontal plate 203. The left and right sides of the horizontal plate 203 are respectively fixedly connected to a first magnetic block 204. The first magnetic block 204 is a positive pole. The rear end face of the first magnetic block 204 is adsorbed and connected to a second magnetic block 205. The second magnetic block 205 is a negative pole. The outer wall of the second magnetic block 205 is fixedly connected to the front of the grid 201.

[0022] The grid 201 in the protective structure 2 can block the particles in the flue gas. At the same time, the adsorption plate 202 inside the grid 201 can adsorb the odor in the flue gas through its own activated carbon grid material, thereby realizing flue gas treatment. The horizontal plate 203 is pulled forward to separate the first magnetic block 204 from the second magnetic block 205. The moving horizontal plate 203 gradually separates the adsorption plate 202 from the grid 201. Then, the new adsorption plate 202 is inserted from the right front to the back into the grid 201, so that the first magnetic block 204 and the second magnetic block 205 are adsorbed, thereby ensuring the environmental performance of the energy-saving and environmentally friendly coal-fired hot water boiler and eliminating the limitations of the use of energy-saving and environmentally friendly coal-fired hot water boiler.

[0023] The outer wall interlayer of the shell 1 is fixed with a straight tube 7, and the front and rear ends of the outer wall of the straight tube 7 are respectively fixed with flanges 8. The opening and closing structure 3 includes a hinge 301 and a door panel 302. The left connection of the rear end face of the hinge 301 is fixed with the front of the shell 1, and the right connection of the rear end face of the hinge 301 is fixed with the left front of the door panel 302. The door panel 302 can be rotated by the hinge 301. The right side of the front of the door panel 302 is fixed with a first handle 303. The first handle 303 is convenient for driving the door panel 302 to rotate. The outer wall of the door panel 302 is plugged into the front groove of the shell 1.

[0024] Working principle:

[0025] Energy-saving and environmentally friendly coal-fired hot water boiler preparation work:

[0026] The flange 8 on the outer wall of the straight pipe 7 is connected to the flange of the external water pipe, and then the pipes on the left and right sides of the cross heat exchanger 4 are plugged into the external water pipe. The plugging is done by wrapping a water stop tape around the pipe connection, and then the second handle 6 is used to pull the box body 5 forward to separate it from the shell 1, and then the fuel is put into the box body 5, and then the box body 5 is pushed back into the inside of the shell 1, and then the door panel 302 is pulled forward by the first handle 303, so that the door panel 302 is flipped forward and opened in conjunction with the hinge 301, and then the fire source is sent into the shell 1 to ignite the fuel, and finally the door panel 302 is rotated in the opposite direction to close it. At this time, the water source enters the straight pipe 7 from the front. Due to the high temperature generated by the combustion of the fuel inside the shell 1, the shell 1 will heat up, and the temperature is transmitted to the straight pipe 7 for heating. At the same time, the high-temperature flue gas is transported upward and passes through the cross heat exchanger 7. The cross heat exchanger 7 can heat the water source passing through the internal pipe, realizing the use of heat below the inside of the shell 1, increasing the use of energy, completing multi-water source heating at the same temperature, and achieving energy saving.

[0027] Energy-saving and environmentally friendly coal-fired hot water boiler flue gas treatment:

[0028] After the high-temperature flue gas passes through the cross heat exchanger 4, the grid 201 can block the particles in the flue gas. At the same time, the adsorption plate 202 inside the grid 201 can adsorb the odor in the flue gas through its own activated carbon grid material, thereby realizing flue gas treatment. The horizontal plate 203 is pulled forward to separate the first magnetic block 204 from the second magnetic block 205. The moving horizontal plate 203 gradually separates the adsorption plate 202 from the grid 201, and then the new adsorption plate 202 is inserted from the right front to the back into the grid 201, so that the first magnetic block 204 and the second magnetic block 205 are adsorbed. Example 2:

[0029] Refer to the attached Figure 1-2 : In this embodiment, an energy-saving and environmentally friendly coal-fired hot water boiler with a built-in cross heat exchanger also includes a temperature detector 9, and the rear end surface of the temperature detector 9 is fixedly connected to the upper front surface of the shell 1.

[0030] Working principle:

[0031] The detection end of the temperature detector 9 passes through the shell 1 and is located inside, and can monitor the temperature inside the shell 1 in real time. When the temperature inside the shell 1 is lower than the temperature set by the temperature detector 9, the temperature detector 9 will issue an alarm to remind the operator to add fuel. The fuel is added at the door panel 302.

[0032] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
