[0002] Coal-to-methanol refers to the process of using coal as a raw material and converting it into methanol through chemical reactions. Coal is an abundant fossil fuel resource, and its main components are elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur. The technological process of coal-to-methanol mainly includes four steps: coal gasification, gas purification, methanol synthesis, and methanol refining. During the methanol vaporization production process, it is necessary to perform dust removal on the generated crude methanol gas, and a back-blowing device needs to be installed on the dust removal box.

[0003] When the existing back-blowing device of the methanol gasification system is in use, the back-blowing nozzle is arranged above the dust removal cloth bag. When back-blowing, the blown high-pressure gas cannot directly blow into the inner side of the dust removal cloth bag, thereby affecting the back-blowing dust removal effect of the dust removal cloth bag. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a back-blowing device for a methanol vaporization system. By setting the blowing pipe, blowing nozzle, blowing side holes, and blowing bottom holes, the blowing nozzle extends into the inner side of the dust removal cloth bag. When dust removal by blowing is required, the high-pressure gas blows out through the blowing side holes and blowing bottom holes on the blowing nozzle, so that the high-pressure gas directly and accurately enters and exits the inner side of the dust removal cloth bag, ensuring that the dust on the outer side of the dust removal cloth bag is vibrated off and ensuring the back-blowing dust removal effect of the dust removal cloth bag, and effectively solving the problems in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A back-blowing device for a methanol vaporization system, including a high-pressure gas storage tank. A pulse solenoid valve is installed on the upper side of the high-pressure gas storage tank through a pipeline. One side of the pulse solenoid valve is connected to a blowing horizontal pipe through a pipeline. Blowing pipes are equidistantly installed on the side of the blowing horizontal pipe away from the pulse solenoid valve. Blowing nozzles are equidistantly installed on the blowing pipes. Blowing side holes are turned on the circumferential side of the lower end of the blowing nozzle, and a blowing bottom hole is turned at the center of the lower end of the blowing nozzle.

[0006] Further, a dust removal box is arranged on one side of the high-pressure gas storage tank. An air outlet pipe is connected to one side of the upper part of the dust removal box through bolts.

[0007] Further, a ash hopper is welded to the lower part of the dust removal box. An air inlet pipe is arranged on the lower side of the high-pressure gas storage tank, and the air inlet pipe is welded to the dust removal box.

[0008] Further, dust removal cloth bags are installed inside the dust removal box corresponding to the outer side positions of the blowing nozzles, and the dust removal box and the dust removal cloth bags are connected through bolts.

[0009] Further, the high-pressure gas storage tank is connected to the dust removal box by bolts, and the blowing cross pipe is connected to the dust removal box by bolts.

[0010] Further, the blowing pipe is connected to the blowing cross pipe by threads, and the blowing head is connected to the blowing pipe by threads.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the arranged blowing pipe, blowing head, blowing side holes and blowing bottom holes, the blowing head extends into the inner side of the dust removal cloth bag. When dust removal by blowing is required, high-pressure gas is blown out through the blowing side holes and blowing bottom holes on the blowing head, so that the high-pressure gas directly and accurately enters and exits the inner side of the dust removal cloth bag, ensuring that the dust on the outer side of the dust removal cloth bag is removed by vibration and guaranteeing the effect of back blowing and dust removal of the dust removal cloth bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, this embodiment provides a technical solution: an anti-blowing device for a methanol vaporization system, including a high-pressure gas storage tank 5. A pulse solenoid valve 6 is installed on the upper side of the high-pressure gas storage tank 5 through a pipeline. One side of the pulse solenoid valve 6 is connected to a blowing cross pipe 11 through a pipeline. Blowing pipes 7 are equidistantly installed on the side of the blowing cross pipe 11 away from the pulse solenoid valve 6. Blowing nozzles 8 are equidistantly installed on the blowing pipes 7. A blowing side hole 9 is machined on the circumferential side of the lower end of the blowing nozzle 8, and a blowing bottom hole 10 is machined at the center of the lower end of the blowing nozzle 8.

[0020] As Figures 1-4 shown, when anti-blowing dust removal is required, the pulse solenoid valve 6 is opened, and the high-pressure gas inside the high-pressure gas storage tank 5 is sent into the blowing nozzle 8 along the blowing cross pipe 11 and the blowing pipes 7, and is ejected through the blowing side hole 9 and the blowing bottom hole 10 of the blowing nozzle 8, so that the high-pressure gas is directly blown into the inside of the dust removal cloth bag 12, and then the high-pressure gas blows the inside of the dust removal cloth bag 12, causing the dust on the outer side of the dust removal cloth bag 12 to vibrate and fall into the ash hopper 4, and the dust on the dust removal cloth bag 12 is collected into the ash hopper 4.

[0021] A dust removal box 3 is arranged on one side of the high-pressure gas storage tank 5. An air outlet pipe 2 is connected to one side of the upper part of the dust removal box 3 through bolts.

[0022] As Figure 1 and 3 shown, the air outlet pipe 2 can discharge the dust-removed gas.

[0023] An ash hopper 4 is welded to the lower part of the dust removal box 3. An air inlet pipe 1 is arranged on the lower side of the high-pressure gas storage tank 5, and the air inlet pipe 1 is welded to the dust removal box 3.

[0024] As Figure 1 shown, the ash hopper 4 can collect the dust falling from the dust removal cloth bag 12, and the air inlet pipe 1 can send the methanol gas to be dust-removed into the inside of the dust removal box 3.

[0025] A dust removal cloth bag 12 is installed inside the dust removal box 3 at a position corresponding to the outside of the blowing nozzle 8, and the dust removal box 3 is connected to the dust removal cloth bag 12 through bolts.

[0026] As Figures 1-4 shown, the dust removal cloth bag 12 can perform dust removal treatment on the methanol gas, and the dust is adsorbed by the dust removal cloth bag 12, so that the dust in the gas is dust-removed.

[0027] The high-pressure gas storage tank 5 is connected to the dust removal box 3 through bolts, and the blowing cross pipe 11 is connected to the dust removal box 3 through bolts.

[0028] As Figures 1-4 shown, high-pressure gas is stored inside the high-pressure gas storage tank 5. After the pulse solenoid valve 6 is opened, the high-pressure gas inside the high-pressure gas storage tank 5 can be transported into the blowing nozzle 8.

[0029] The injection pipe 7 and the horizontal injection pipe 11 are connected by threads, and the injection head 8 and the injection pipe 7 are connected by threads.

[0030] The working principle of an anti-blowing device for a methanol vaporization system provided by the present utility model is as follows: As Figures 1-4 shown, when it is necessary to remove dust from methanol gas, the gas enters the dust removal box 3 through the air inlet pipe 1, the dust removal cloth bag 2 filters and adsorbs the dust in the gas, and the dust-removed gas can be discharged through the air outlet pipe 2. When it is necessary to blow back and remove the filtered dust on the dust removal cloth bag 12, the pulse solenoid valve 6 is opened, and the high-pressure gas in the high-pressure gas storage tank 5 is sent into the injection head 8 through the horizontal injection pipe 11 and the injection pipe 7, and is quickly blown out through the injection side holes 9 and the injection bottom holes 10 at the lower part of the injection head 8, so that the high-pressure gas is directly blown into the inner side of the dust removal cloth bag 12, and the dust attached to the outer side surface of the dust removal cloth bag 12 falls into the inner side of the ash hopper 4, so that the dust on the dust removal cloth bag 12 obtains an effective anti-blowing dust removal effect.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
