1) at dump surface sprinkling coverture, to reduce the area of contact of dump and air, thus the object of isolated air is reached;
2) method of trickle or plug in metal bar is adopted, to evacuate the heat of dump accumulated inside.
But, existing mode or cost is higher, otherwise implementation more complicated, be not easy to operation.In addition, prior art just reduces or evacuates the heat that dump gathers, and is not used, causes serious waste.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned defect existing in prior art, provides one to alleviate self-ignition of coal pile, the device of the heat that dump can be utilized again to gather.
The technical scheme that solution the utility model technical matters adopts is:
The utility model provides a kind of device alleviating self-ignition of coal pile, and described device comprises the pipeline be arranged at bottom dump and/or in the middle part of dump, and liquid to be heated is accessed in one end of described pipeline, and the other end is connected to recovery system.
Preferably, the base portion of described pipeline is that periodic rectangular is wavy, periodic sinusoidal is wavy or periodic serrations is wavy.
Preferably, described pipeline is divided into multistage, and often the end of adjacent two segment pipes all adopts adapter to connect.
Preferably, the material of described adapter is copper.
Preferably, described pipeline adopts many, and one end of many described pipelines also connects the described liquid to be heated of rear access, and the other end of many described pipelines is also connected to described recovery system after connecing.
Preferably, described pipeline adopts metric system pipe.
Further preferably, the material of described metric system pipe is copper.
Preferably, described liquid to be heated is water, and described recovery system comprises the domestic water facility be connected with each user.
Preferably, described recovery system also comprises the heating arrangement being arranged on and being also connected with the two respectively between described pipeline with described domestic water facility, and described heating arrangement exports described domestic water facility to after heating further for the heating liquid exported described pipeline.
Preferably, described heating arrangement is the heating system that colliery or power plant are equipped with.
Beneficial effect:
The device of alleviation self-ignition of coal pile described in the utility model utilizes and is laid on bottom dump and/or the pipeline at middle part, by flowing in ducted water, the heat of dump accumulated inside is taken away gradually, the temperature of water obtains rising to a certain extent in this process, recycle existing heating arrangement and post bake is carried out to the water heated by dump, namely can be used for heating, having a bath until be heated required temperature, thus self-ignition of coal pile odds can be reduced, the heat that dump can be utilized again to gather, can also reduce the fuel of heating needed for domestic water.
Simple, the required energy consumption of the structure of device described in the utility model is low, has great promotional value at large coal mine and power plant.
Accompanying drawing explanation
The principle of work schematic diagram of the device of the alleviation self-ignition of coal pile that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structural representation of the pipeline in Fig. 1.
In figure: 1-water cock; 2-pipeline; 3-dump; 4-heating arrangement; 5-domestic water facility; 6-adapter.
Detailed description of the invention
For making those skilled in the art understand the technical solution of the utility model better, below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model embodiment provides a kind of device alleviating self-ignition of coal pile, can absorb the characteristic of heat when it relies on liquid to be high temperature by low-temperature transformation, is taken out of by the heat of dump accumulated inside and can be recycled.
As shown in Figure 1, described device comprises and is arranged at bottom dump 3 and/or the pipeline 2 at middle part, liquid to be heated is accessed by water cock 1 in one end of described pipeline 2, and the other end is connected to recovery system, thus is taken out of by the heat of dump accumulated inside and send into recovery system.In the present embodiment, pipeline 2 adopts copper metric system pipe, is both convenient to processing and fabricating, has again good heat conduction effect, advantage that compressive strength is high; Described liquid to be heated is water (tap water), can certainly for obtaining the liquid utilized after other heating.
In order to take away the heat of dump accumulated inside as far as possible, as shown in Figure 2, the base portion of described pipeline 2 can be set in periodic rectangular wavy, to make pipeline 2 flipe that takes the shape of the letter U be placed in bottom dump 3 and/or middle part, ensures area of contact and the contact time of water and the dump circulated in pipeline.In addition, the base portion of described pipeline 2 also can be set to that periodic sinusoidal is wavy or periodic serrations is wavy, or other can increase water in pipeline and the area of contact of dump and the shape of contact time.
As shown in Figure 2, described pipeline 2 can be divided into multistage, and often the end of adjacent two segment pipes all adopts adapter 6 to connect, and is more convenient for manufacturing and laying compared to the pipeline of integral type.Wherein, described adapter 6 also can be made of copper.
In order to increase area of contact and the contact time of water in pipeline and dump further, described pipeline adopts many (not shown)s, one end of many described pipelines utilizes existing connection mode and connects rear access water, and the other end of many described pipelines utilizes existing connection mode and is connected to described recovery system after connecing.
In the present embodiment, as shown in Figure 1, described recovery system comprises the domestic water facility 5 be connected with each user, thus pipeline 2 can be exported heated by dump 3 after water be supplied to each user through domestic water facility 5.
Preferably, described recovery system also comprises the heating arrangement 4 being arranged on and being also connected with the two respectively between described pipeline 2 with described domestic water facility 5, described heating arrangement 4 exports described domestic water facility 5 to after heating further for the water heated exported described pipeline, for heating or having a bath.Wherein, described heating arrangement can be the heating system that colliery or power plant are equipped with, i.e. existing heating system.
In the present embodiment, the principle of work of the device of described alleviation self-ignition of coal pile is:
During use, opened by water cock 1, the water of outflow is flow through by the bottom of pipeline 2 at dump 3.Because pipeline 2 takes the shape of the letter U folding layout bottom dump, ensure that the area of contact and contact time that circulate in the water in pipeline 2 and dump, fully can take away the heat of dump accumulated inside, both be conducive to alleviation self-ignition of coal pile, and can water temperature have been increased again.The water flowed out from pipeline 2 is transported to heating arrangement 4, after being heated to meet the temperature of domestic water, sends to each user by domestic water facility 5.
Be understandable that, the illustrative embodiments that above embodiment is only used to principle of the present utility model is described and adopts, but the utility model is not limited thereto.For those skilled in the art, when not departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
