Detailed Description
The technical solutions in the embodiments of the present disclosure will be described more fully hereinafter with reference to the non-limiting exemplary embodiments shown in the accompanying drawings and detailed in the following description, taken in conjunction with the accompanying drawings, which illustrate, more fully, the exemplary embodiments of the present disclosure and their various features and advantageous details. It should be noted that the features illustrated in the drawings are not necessarily drawn to scale. The present disclosure omits descriptions of well-known materials, components, and process techniques so as not to obscure the example embodiments of the present disclosure. The examples given are intended merely to facilitate an understanding of ways in which the example embodiments of the disclosure may be practiced and to further enable those of skill in the art to practice the example embodiments. Thus, these examples should not be construed as limiting the scope of the embodiments of the disclosure.
Unless otherwise specifically defined, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which this disclosure belongs. The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. Further, in the various embodiments of the present disclosure, the same or similar reference numerals denote the same or similar components.
The raw limestone powder warehouse shown in fig. 1 is not sealed structurally, and equipment such as a system motor and the like are common motors and the like, so that great potential safety hazards are caused, and the raw limestone powder warehouse can system cannot effectively seal gas. A water seal structure 8 is additionally arranged at the bottom of a liquid level overflow pipe 3 of a traditional limestone powder bin to seal gas, and an exhaust pipeline 10 is additionally arranged at the top of a raw limestone powder bin, so that generated inflammable gas is discharged to atmosphere for dilution, and one end of a liquid level water replenishing pipeline 4 of the raw limestone powder bin is connected to a washing water system pipeline 9 to be 100 cm below the liquid level of the limestone powder bin. If not set up the sparge water system pipeline 9, liquid level moisturizing pipeline 4 produces umbelliform water column and scatters the phenomenon at lime stone powder storehouse top during the moisturizing, causes the carbide slag powder that falls to follow the exhaust pipe and discharges the atmosphere, if set up the sparge water system pipeline 9, deepens the production of umbelliform water column in the liquid level 100 cm department. Install umbelliform dusting wash water system 11 downwards additional at 50 centimetres departments apart from limestone flour storehouse top with exhaust duct 10, because the carbide slag falls into the aquatic, can produce gas, gas takes out the carbide slag powder that has not come to the reaction from the blast pipe, installs dusting wash water system 11 additional and just can eliminate the carbide slag powder that carries along with exhaust apparatus.
As shown in fig. 2, it is a structure diagram of the carbide slag system of the present embodiment. The method comprises the following steps: the device comprises a limestone powder storage tank 1, a liquid level overflow trench 2, a liquid level overflow pipe 3, a liquid level water replenishing pipeline 4, a limestone powder discharge pipeline 5, a water seal structure 8, a washing water system pipeline 9, an exhaust pipeline 10 and a powder removal washing water system 11; wherein,
a limestone powder discharge pipeline 5 is arranged at the top of the limestone powder storage tank 1, a liquid level water replenishing pipeline 4 is arranged on the limestone powder storage tank 1, the liquid level water replenishing pipeline 4 is arranged on one side of the limestone powder discharge pipeline 5, and the exhaust pipeline 10 is arranged on the other side of the limestone powder discharge pipeline 5; the one end of liquid level moisturizing pipeline 4 with wash water system pipeline 9 links to each other, liquid level moisturizing pipeline 4 through the pipeline with remove powder wash water system 11 and link to each other, remove powder wash water system 11 set up in among the exhaust duct 10, the one end of liquid level overflow pipe 3 set up in on the lateral wall of limestone flour storage tank 1, the other end of liquid level overflow pipe 3 extends in liquid level overflow trench 2, set up on the liquid level overflow pipe 3 water seal structure 8.
As can be seen from fig. 2, the gate valve 6 is disposed on the limestone powder discharge duct 5. When the carbide slag is added into the raw limestone powder bin, the carbide slag and water are mixed to immediately generate combustible gas acetylene, and the modified carbide slag system based on the raw limestone powder bin shown in fig. 2 structurally belongs to a closed space. And a water sealing structure 8 is additionally arranged at the bottom of the liquid level overflow pipe 3 for gas sealing. As can be seen from fig. 2, the water sealing structure 8 is a U-shaped structure. One end of the liquid level water supplementing pipeline 4 is connected with the flushing water system pipeline 9, and the flushing water system pipeline 9 extends to a position below the liquid level in the limestone powder storage tank 1. And the original water supplementing system is modified to be deep below the liquid level for supplementing water. The exhaust pipeline 10 is additionally provided with a powder-removing flushing water system 11, so that carbide slag is prevented from being discharged into the atmosphere along with gas. In this technical scheme, the dusting rinse water system 11 is an umbrella-shaped dusting rinse water system.
The improved system is effectively sealed, so that gas does not leak into the limestone powder cabin room 7, and the carbide slag powder is not discharged into the atmosphere. In the sealing structure, acetylene and carbon monoxide gas are not generated, so that the harm event caused by the generation of toxic gas is reduced to the minimum, and the effect is obvious.
