Detailed Description
The invention provides a novel supercharged gasifier, which aims to solve the technical problem that in the gasifier in the prior art, due to the fact that the diameter of a finned tube is small, the contact area between a liquid-phase medium and the finned tube is small, and the heat exchange efficiency of the liquid-phase medium passing through the finned tube is low.
Referring to fig. 1, 2 or 3, the novel pressurized gasifier comprises a finned tube 1, an atomization device 2 and a pressurization device, wherein the atomization device 2 is arranged on the finned tube 1; the liquid phase medium flows into the atomizing device 2 from the inlet of the finned tube 1 to the outlet of the finned tube, the atomizing device 2 converts the liquid phase medium into a mist medium under preset pressure, and the mist medium flows from the atomizing device 2 to the outlet of the finned tube 1; the pressurizing device is communicated with the atomizing device 2 and is used for increasing the flowing pressure of the atomized medium in the atomizing device 2.
Referring to fig. 4, the liquid-phase medium flows into the atomizing device 2 through the finned tube 1, and when the pressure applied to the liquid-phase medium meets a preset pressure, the atomizing device 2 converts the liquid-phase medium into a mist-like medium. It should be understood that the liquid medium is in a low-temperature liquid state, and the mist medium is also in a low-temperature liquid state, and the difference between the two is: the liquid medium is a continuous whole formed by gathering a plurality of liquid particles, and the mist medium is liquid particles which are mutually dispersed. After the liquid-phase medium is converted into the atomized particles by the atomization device 2, the total volume of the liquid-phase medium is kept unchanged, but the contact area between the liquid-phase medium and the outside (especially, the total surface area of the liquid-phase medium or the atomized medium) is increased; the single atomized medium is liquid particles, has small mass and small volume, and can flow along with the flow of gas (especially the gas which is converted into a gas-phase medium after the liquid-phase medium absorbs heat). The atomized medium flows from the atomizing device 2 to the outlet direction of the finned tube 1; a part of the atomized medium is sprayed to the inner wall of the atomization device 2, and the part of the atomized medium is converted into a gas-phase medium through heat exchange with the inner wall of the atomization device 2; the rest part of the atomized medium flows in the finned tube 1 together with the gaseous medium, and the rest part of the atomized medium is sprayed on the finned tube 1 successively, so that the heat of the finned tube 1 is absorbed successively and then converted into the gaseous medium.
The liquid medium and the atomized medium transformed by the atomization device 2 have the same mass, the total surface area of the atomized medium is larger than that of the liquid medium, and the single atomized medium is granular and can move together with the gas; meanwhile, the liquid-phase medium can only form a heat exchange structure with one section of the finned tube 1 and is converted into a gas-phase medium, so that the contact area between the liquid-phase medium and the finned tube 1 is small; and the fog-like medium can move along with the gas together, so that the fog-like medium can sequentially form a heat exchange structure with the multi-section finned tubes 1 and is converted into a gas-phase medium, and the contact area of the fog-like medium and the finned tubes 1 is larger than that of the liquid-phase medium and the finned tubes 1.
In the actual working process of the atomizing device 2, along with the long-time conversion of the liquid-phase medium into the gas-phase medium through the atomizing device 2, the atomizing device 2 tends to be in an icing state or is already frozen, so that the temperature of the atomizing device 2 is reduced; at the same time, the efficiency of the conversion of the atomized medium into the gaseous medium in the atomizing device 2 is reduced, so that the total amount of the gaseous medium in the atomizing device 2 is reduced, and the total amount of the atomized medium discharged out of the atomizing device 2 together with the gaseous medium is increased; so that the gaseous medium is discharged out of the atomizing device 2 together with the gaseous medium, the flow pressure provided by the gaseous medium that can be obtained by the gaseous medium is reduced, and finally the gaseous medium is transformed into the liquid medium again in the atomizing device 2.
Referring to fig. 1, 2 or 3, the pressurizing device communicated with the atomizing device 2 is arranged to make the atomized medium in the atomizing device 2 obtain an additional flow pressure, so that the atomized medium in the atomizing device 2 can be ensured to be smoothly discharged out of the atomizing device 2 under a sufficient flow pressure.
Therefore, according to the novel supercharged gasifier provided by the invention, the atomization device is arranged on the finned tube, and after the liquid-phase medium is converted into the vaporous particles through the atomization device, the surface area of the original liquid-phase medium is increased, the heat exchange area between the original liquid-phase medium and the finned tube is increased, and the heat exchange efficiency is improved; therefore, the gasifier in the prior art is solved, and the technical problem that the heat exchange efficiency of the liquid-phase medium passing through the finned tube is low due to the fact that the diameter of the finned tube is small, the contact area of the liquid-phase medium and the finned tube is small.
In addition, according to the novel supercharged gasifier provided by the invention, the supercharging device is arranged on the basis of the finned tube and the atomizing device, and the extra flow pressure is obtained by the atomized medium in the atomizing device through the supercharging device, so that the technical problem that the efficiency of converting a liquid-phase medium into a gas-phase medium in the atomizing device is reduced due to the reduction of the temperature of the atomizing device, and the other atomized media are difficult to obtain sufficient flow pressure from the gas-phase medium, so that the atomized medium is converted into the liquid-phase medium in the atomizing device again is solved.
Further, referring to fig. 1, 2 or 3, the pressurization device includes a pressurization device and a pressurization pipe 5, and the pressurization device is communicated with the atomization device 2 through the pressurization pipe 5; the gas-phase medium which is the same as the liquid-phase medium is pressurized by the pressurization equipment and then is transmitted into the inner cavity of the atomization device 2.
The medium pressurized by the pressurizing device is a gas-phase medium, and the gas-phase medium and the liquid-phase medium flowing into the atomizing device 2 are in the same substance. After the pressurization equipment pressurizes the gas-phase medium, the gas-phase medium is conveyed into the atomization device 2 through a pipeline, so that the gas-phase medium forms a pressurization state for the atomized medium in the atomization device 2; the mixture of the gaseous medium and the atomized medium flows out of the atomizing device 2 together, and when the atomizing device 2 works for a long time, no matter whether the atomizing device 2 tends to be frozen or is frozen, the gaseous medium conveyed by the pressurizing equipment can pressurize the atomized medium in the atomizing device 2.
Therefore, by providing the pressurization device and the pressurization pipe 5, the inside mist medium of the atomization device 2 can keep a sufficient flow pressure in the gas-phase medium which is conveyed by the pressurization device and is from the outside of the atomization device 2 under the long-time operation, and the situation that the mist medium is converted into the liquid-phase medium again in the atomization device 2 due to insufficient flow pressure of the mist medium can be avoided.

The gas-phase medium in the gas-phase medium gas storage tank 6 is utilized, and the gas-phase medium is transmitted into the atomization device 2 through the pressurization pipe 5 through the pressure of the gas-phase medium in the gas storage tank, so that the atomized medium in the atomization device 2 can obtain continuous pressure provided by the gas-pressure medium.
The gas-phase medium gas storage tank 6 is set as supercharging equipment, the structure is very simple, the economic cost is low, and the supercharging equipment can be realized only by arranging the supercharging pipe 5 between the gas-phase medium gas storage tank 6 and the novel supercharging gasifier provided by the invention.

By adopting a closed-loop control structure, the temperature sensor can remotely transmit a temperature electric signal to a control chamber far away from the gasifier through relay equipment after the gasifier realizes automatic control; a controller in the control room receives the temperature electric signal, and transmits a control signal to the control valve through the relay equipment; the arrangement mode can realize the isolation control of the gasifier and the control equipment, and ensure the safety of the operator operating the controller or the operator operating the controller.
In addition to all the foregoing, it is also possible to provide check valves on each of the 2 vaporizers having a parallel structure according to the actual situation, so that it is possible to prevent any gas-phase medium from flowing into the atomizing device 2 from the outlet of the atomizing device 2 of any one vaporizer.
In addition to all the foregoing, with reference to fig. 4, the foregoing atomizing device 2 is preferably configured in the following manner:
the atomizing device 2 comprises a pressure type nozzle; when the flowing pressure of the liquid-phase medium meets the preset pressure, the liquid-phase medium is converted into the mist-like medium through the pressure type nozzle.
The liquid-phase medium flows into the pressure type nozzle through the finned tube 1, when the flowing pressure of the liquid-phase medium (namely, the hydraulic pressure of the liquid-phase medium) reaches a preset pressure, a part of the liquid-phase medium at the outlet of the pressure type nozzle is sprayed out of the pressure type nozzle by the flowing pressure formed by all the liquid-phase medium, and scattered mist-like particles are formed after the part of the liquid-phase medium is sprayed out.
The pressure type nozzle has a simple structure, is easy to process and manufacture, and has high reliability when the pressure type nozzle is actually used. The pressure type nozzle has small volume and is convenient to be arranged on the finned tube 1; meanwhile, the atomization pressure of the pressure type nozzle is the flow pressure of the pressure type nozzle, so that the manufacturing cost and the maintenance cost of the novel air-temperature gasifier provided by the invention are reduced.
Preferably, a guide shell is additionally arranged on the atomizing device 2, and the pressure type nozzle is arranged in the guide shell; the inner diameter of the guide shell is larger than or equal to the spraying diameter of the pressure type nozzle.
Because the inner diameter of the guide shell is larger than or equal to the spraying diameter of the pressure type nozzle, the situation that the atomized particles are contacted with the inner wall of the guide shell and are converted into liquid-phase medium again after being sprayed out from the pressure type nozzle is avoided as much as possible.
It should be understood that the guide cylinder is preferably provided in a cylindrical shape, and the extension direction of the axis thereof should be parallel to the flow direction of the liquid medium in the finned tube 1, so as to prevent the liquid medium from being hindered by the guide cylinder to reduce the flow pressure as much as possible. The through hole of the pressure nozzle is arranged in the same direction as the extension direction of the axis of the guide shell, and preferably, the through hole of the pressure nozzle and the axis of the guide shell are arranged in a coaxial state.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are included in the scope of the present invention.
