The specific structure of the leachate circulation heating apparatus 100 according to the embodiment of the present invention is described below with reference to fig. 1.
According to the leachate circulation heating device 100 of the embodiment of the invention, the leachate circulation heating device 100 is used for circularly heating leachate in the garbage pool 200, and the leachate circulation heating device 100 comprises a collecting pool 10, a heating box 20, a leachate spray pipe 30 and a pressurizing pump assembly 40. The collection tank 10 is adapted to be connected to the waste tank 200 for collecting leachate in the waste tank 200, the heating tank 20 has a flow-through inlet 220 and a flow-through outlet 230, the flow-through inlet 220 is connected to the collection tank 10, and heating means (not shown) for heating the influent leachate are provided on the heating tank 20. One end of the leachate spray pipe 30 is connected with the circulation outlet 230, the other end of the leachate spray pipe 30 is connected with the garbage pool 200, the leachate spray pipe 30 is used for spraying heated leachate into the garbage pool 200, and the spray outlet of the leachate spray pipe 30 is arranged at the inlet of the garbage pool 200. The booster pump assembly 40 is used to drive the leachate within the leachate lance 30 towards the waste pool 200.
It will be appreciated that the leachate in the waste tank 200 is pressurized by the pressurizing pump assembly 40 provided on the leachate lance 30 and finally sprayed into the waste tank 200 after flowing into the heating tank 20 and being heated by the heating means. The heated leachate can heat the garbage, so that the garbage in the garbage pool 200 is heated and thawed in severe cold winter, and the fermentation effect of the garbage is improved. The pressurizing pump assembly 40 can pressurize the leachate in the leachate spray pipe 30, so that the leachate is sprayed when flowing out of the spray outlet, and uniform heating of the garbage can be realized. Meanwhile, since the spray opening of the leachate spray pipe 30 is arranged at the inlet of the garbage pool 200, leachate sprayed from the spray opening is always sprayed to garbage newly poured into the garbage pool 200, so that the probability of burying the spray opening by the garbage can be reduced. In addition, compared with the scheme of arranging the leachate delivery pipe in the garbage pool 200, the scheme of arranging the ejection outlet of the leachate spray pipe 30 at the inlet of the garbage pool 200 can heat garbage more uniformly and can heat the garbage which is poured in again rapidly.
According to the leachate circulation heating device 100 of the embodiment of the invention, by arranging the pressurizing pump assembly 40 and arranging the ejection outlet of the leachate spray pipe 30 at the inlet of the garbage pool 200, the leachate circulation heating device 100 reduces the probability of burying the leachate spray pipe 30 by garbage, improves the uniformity of heating garbage, and can rapidly heat the newly poured garbage.
In some embodiments, the discharge outlet of the leachate lance 30 is positioned at the discharge inlet of the waste pit 200, and a metal hose is used at the end of the leachate lance 30 adjacent to the waste pit 200. Therefore, when the garbage is not required to be heated in summer, the user can hang the metal hose on the outer wall of the discharging door. Such an arrangement prevents the leachate spray pipe 30 from being buried and the spray pipe outlet from being blocked, as compared to the arrangement in which the leachate spray pipe 30 is fixed within the waste pool 200.
In some embodiments, the heating device is a scroll-type steam heater, the scroll-type steam heater is disposed in the heating box 20, and a steam inlet pipe 210 for introducing steam to the scroll-type steam heater is disposed on the heating box 20. Therefore, the leachate and the steam can be fully and directly contacted and heat exchanged, and the purpose of enhancing the heating effect of the leachate is achieved.
Specifically, in some embodiments, the vortex steam heater may be from steam extracted from the turbine, thus fully utilizing the waste heat of the turbine and saving energy.
In some embodiments, leachate circulation heating device 100 further includes a temperature control device 50, temperature control device 50 being coupled to heating tank 20, temperature control device 50 detecting the temperature of leachate exiting flow outlet 230 and regulating the amount of steam that is channeled to the scroll steam heater.
It is understood that too high a temperature of the leachate will destroy the active enzymes in the leachate and too low a temperature of the leachate will result in an undesirable heating effect of the waste. Therefore, the temperature of the leachate must be controlled, so that not only the activity of the active enzyme can be achieved, but also the heating and fermentation effects on the garbage can be ensured.
Specifically, the temperature control device 50 includes a temperature sensor 510, a first check valve 520, and a regulating valve 530, the temperature sensor 510 is disposed at the flow outlet 230, the first check valve 520 is disposed on the steam inlet pipe 210, the regulating valve 530 is located upstream of the first check valve 520 in the flow direction of the steam, and the regulating valve 530 is electrically connected to the temperature sensor 510.
It is understood that the first check valve 520 may prevent the backflow phenomenon of the leachate. The temperature sensor 510 may detect the temperature of the leachate at the circulation outlet 230 and feed back the detection result to the regulating valve 530, and the regulating valve 530 may regulate the amount of steam introduced into the scroll-type steam heater, thereby regulating the temperature of the leachate. Thus, the temperature sensor 510 and the regulating valve 530 are combined to provide a proper temperature for the leachate to flow out of the flow outlet 230.
Advantageously, the temperature of the leachate at the outlet is controlled to be around 55 ℃.
In some embodiments, the leachate circulation heating apparatus 100 further comprises a transfer pump 70, the transfer pump 70 being configured to drive the leachate in the collection tank 10 towards the heating tank 20. Thereby, it is ensured that the leachate in the collection tank 10 flows continuously towards the heating tank 20, so that the landfill leachate can be heated circularly.
In some embodiments, leachate circulation heating apparatus 100 further comprises: two first switching valves 60, the two first switching valves 60 are provided at the circulation inlet 220 and the circulation outlet 230, respectively. Thus, when the waste does not need to be heated, the two first switching valves 60 may be closed so that the leachate cannot flow out of/into the heating tank 20.
In some embodiments, the booster pump assembly 40 includes a booster pump 410, a second check valve 420, and two second switching valves 430, the booster pump 410 being disposed in series on the leachate spout 30, the booster pump 410 being configured to drive the leachate within the heating tank 20 to flow toward the waste tank 200, the second check valve 420 being located downstream of the booster pump 410 in a direction of flow of the leachate, the two second switching valves 430 being located upstream of the booster pump 410 and downstream of the second check valve 420, respectively, in a direction of flow of the leachate.
It is understood that the first check valve 520 may prevent the backflow phenomenon of the leachate. The pressurizing pump 410 can pressurize the leachate in the leachate spray pipe 30, so that the leachate is sprayed when flowing out of the spray outlet, and uniform heating of the garbage can be realized. Further, two second switching valves 430 are located upstream of the pressurizing pump 410 and downstream of the second check valve 420, respectively, in the flow direction of the leachate, whereby when the waste does not need to be heated, the two second switching valves 430 can be closed so that the leachate cannot enter the waste tank 200.
Specifically, the pressurizing pump assembly 40 is provided in plurality, and the plurality of pressurizing pump assemblies 40 are connected in parallel to the leachate spray pipe 30.
More specifically, only one of the plurality of booster pump assemblies 40 is in the active state at the same time, and the remaining booster pump assemblies 40 are in the standby state.
Thus, it is possible to ensure that one pressurizing pump assembly 40 is always kept in operation when a worker overhauls the pressurizing pump assembly 40, and thus, the worker can perform overhauling work while ensuring that the leachate circulation heating device 100 heats leachate.
In some embodiments, a plurality of spray heads 310 are provided on leachate spray pipe 30. It will be appreciated that the nozzle connecting pipe may be connected to the plurality of nozzles 310 at one end of the leachate spray pipe 30 adjacent to the inlet of the waste pool 200, thereby allowing leachate to be uniformly sprayed on the surface of the waste in the waste pool 200, and ensuring heating uniformity.
