Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 3, which are schematic structural views of the high-efficiency sewage evaporator provided by the present invention. The high-efficiency sewage evaporator can be used for treating various sewages such as domestic sewage, industrial sewage and the like. It is known that any sewage comprises sewage and impurities, which are treated by evaporation, i.e. the sewage can be separated from the impurities. The impurities can be sludge, organic matter of kitchen waste, metal oxide and the like. The high-efficiency sewage evaporator comprises a bracket 10, an evaporation cavity 20 arranged on the bracket 10, a sewage partition plate 30 arranged in the evaporation cavity 20, a heating device 40 arranged to intersect with the sewage partition plate 30, and a sewage leading-in device 50 arranged above the heating device 40 at a distance from the heating device 40. It is contemplated that the high efficiency sewage evaporator may further include other functional modules, such as mounting assemblies, electrical connections, various valve assemblies, etc., which are well known to those skilled in the art and will not be described in detail herein.

The frame 10 may be a truss structure that supports the evaporation chamber 20 and also forms a space for other components, such as pipes, valves, etc.

The evaporation cavity 20 can be made of double-layer steel plates and heat insulation materials clamped between the double-layer steel plates, so that the temperature can be stored as far as possible, and heat loss is avoided. The evaporation cavity 20 comprises a pot-shaped bottom cover 21 with a sharp bottom, a sewage outlet pipe 22 arranged at the bottom of the pot-shaped bottom cover 21 with the sharp bottom, an air outlet pipe 23 arranged at the top of the furnace body, and thermometers 24 arranged on the side walls of the two furnace bodies. The pot-shaped bottom cover 21 has a frustoconical shape to facilitate the deposition of impurities therein and the outflow of these impurities from the bottom thereof. The sewage outlet pipe 22 is arranged at the bottom of the pot-shaped bottom cover 21 and is used for discharging deposited impurities. However, the amount of the drain pipe 22 to be discharged should match the amount of the stock in the pot-shaped bottom cover 21, which will be described in detail below. The gas outlet pipe 23 is arranged at the top of the furnace body and is used for discharging gas generated by evaporation. The thermometer 24 is used to measure the temperature within the evaporation chamber 20, as will be described in more detail below.

The dividing wall 30 is fixed in the evaporation chamber 20 and includes a plurality of drain holes 31. Preferably, the water baffle 30 is located in a plane perpendicular to the central axis of the evaporation chamber 20. It is conceivable that the water-dirt separator 30 is disposed at the lower middle portion of the evaporation chamber 20 because other components are also assembled in the evaporation chamber 20. The sewage barrier 20 serves to separate or distinguish sewage from impurities.

The heating means 40 comprises a plurality of U-shaped tubes fixed to the dividing wall 30 and connected end to form an interconnected conduit. Two ports of the pipeline are arranged on the outer side wall of the evaporation cavity 20 and are used for being connected with a steam generating device, so that high-temperature steam enters from one end and exits from the other end, and the inner space of the whole evaporation cavity is heated. Both sides of the plurality of U-shaped pipes are located at both sides of the sewage partition plate 30, thereby heating the sewage at both sides of the sewage partition plate 30. In order to make full use of the heat, the length of the U-shaped tubes above the water-sewage separating plate 30 is greater than the length of the U-shaped tubes below the water-sewage separating plate 30.

The sewage introducing device 50 is disposed above the heating device 40, and is used for introducing sewage into the evaporation cavity 20, and making the sewage become steam as much as possible and flow out during the introduction process. The sewage introducing apparatus 50 includes an assembling frame 51 fixed in the evaporation chamber 20 and positioned above the heating apparatus 40, a water separator 52 provided on the assembling frame 51, and at least three water sprayers 53 provided on the water separator 52. The assembly frame 51 is fixed on the inner side wall of the evaporation cavity 20, and the structure thereof can be designed according to actual requirements. In this embodiment, the assembly frame 51 is composed of two steel pipes. The water distributor 52 is fixedly arranged on the assembly frame 51, one end of the water distributor 52 is connected with a water inlet pipeline, and the side wall of the water distributor is provided with at least three water outlet holes. It is of course conceivable that the outlet aperture should be smaller than the inlet conduit aperture to avoid reducing the outlet pressure. The water sprayer 53 is arranged on the water outlet hole of the water separator. It is contemplated that the sprinkler 53 includes a connection pipe 531, a tapered pipe 532 disposed on the connection pipe 531, and a spiral outlet 533 spirally disposed on the tapered pipe 532 in order to adapt to the diameter of the evaporation chamber 20. The connection pipe 531 may be provided on the water separator 52 by means of a screw connection. The large diameter portion of the tapered tube 532 is also threadedly coupled to the other end of the connection tube 531. The spiral water outlet 533 is spirally formed on the sidewall of the conical tube 532. When water flow is ejected from the spiral water outlet 533 under the action of pressure, due to the existence of the spiral water outlet 533, the water flow is spirally ejected out in the radial direction of the evaporation cavity 20 under the action of pressure, so as to achieve the purpose of ejection, and thus, sewage is ejected to four directions and sprinkled on the heating device 40, so as to improve the evaporation efficiency.

During the evaporation of the sewage, the water vapor goes upward, and the impurities fall downward by gravity, so that the impurities fall into the pot-shaped bottom cover 21 through the drain holes 31 of the sewage partition plate 30. Meanwhile, in the process of spraying sewage, the sewage in all the introduced sewage cannot be evaporated in time, and part of the water must enter the pot-shaped bottom cover 21 with the pointed bottom, so that the sewage outlet pipe 22 cannot be opened at the beginning, and the sewage which is not evaporated after being opened at the moment can flow away, and the purpose of full evaporation cannot be achieved. Also, therefore, the sewage pipe 22 should be closed at the beginning. As the sewage water is introduced, more and more impurities are deposited on the pot-shaped bottom cover 21, and the sewage water is above. As the impurities increase, they will block the sewage outlet pipe 22, and the height of the sewage gradually increases until the sewage is located at both sides of the sewage partition plate 30, but the height of the U-shaped pipe below the sewage partition plate 30 should be the same as the depth of the sewage below the sewage partition plate 30, so that the heat in the U-shaped pipe heats the sewage for further evaporation. Meanwhile, as the sewage exists in the pot-shaped bottom cover 21 with the sharp bottom, the impurities are always in a flowable viscous state, so that the impurities containing the sewage can still flow out when the sewage outlet pipe 22 is opened. In order to maintain the depth of the sewage below the sewage partition plate 30, the flow rate of the sewage outlet pipe 22 should be such that the pot-shaped bottom cover 21 always has impurities and the height of the U-shaped pipe below the sewage partition plate 30 is the same as the depth of the sewage below the sewage partition plate 30. Meanwhile, the depth of the sewage in the evaporation cavity 20 should be smaller than the height of the U-shaped pipe, so that the heating device 30 can heat the sewage sufficiently to improve the evaporation efficiency. Of course, the depth of the wastewater in the evaporation chamber 20 should be achieved by the combination of the evaporation amount and the wastewater amount introduced by the wastewater introducing device 50.

Meanwhile, during the working process, the two thermometers 24 are required to detect the temperatures of the two sides of the sewage partition plate 30 all the time, and if the temperatures displayed by the two thermometers 24 are the same, it means that the height of the U-shaped pipe below the sewage partition plate 30 is the same as the depth of the sewage below the sewage partition plate 30. If the temperature of the thermometer 24 on the lower side of the sewage partition plate 30 is higher than the temperature of the thermometer 24 on the upper side of the sewage partition plate 30, it means that the inflow amount of the sewage introducing apparatus 50 is too small, and the purpose of detecting the operation state is achieved.

Compared with the prior art, the efficient sewage evaporator provided by the invention is provided with the sewage partition plate 30, and the heating device 40 is made of a plurality of U-shaped pipes which are connected end to end and are respectively arranged at two sides of the sewage partition plate 30. In operation, sewage is located on both sides of the sewage barrier 30. The impurities are located below the sewage and are kept below the sewage partition plate 30 in the working process of the high-efficiency sewage evaporator all the time, the height of the U-shaped pipe below the sewage partition plate 30 is the same as the depth of the sewage below the sewage partition plate 30, and therefore the U-shaped pipes can be fixedly installed in a plurality of modes, the U-shaped pipes on two sides of the sewage partition plate 30 can heat the sewage, and the efficiency of sewage evaporation is improved. Meanwhile, as the impurities are always kept below the water-sewage partition plate, the sewage can be prevented from flowing out, the sewage is kept at a certain height, the U-shaped pipe is soaked in the sewage, so that the heat in the heating device can be utilized to the maximum extent, the sewage is changed into steam, the sewage evaporation efficiency is further improved, and the steam becomes water which can be reused after being cooled, such as watering flowers, trees and the like.
