Problems solved by technology

[0002] In the prior art, high-temperature distillation is used for the production of mercury, which results in high energy consumption in the mercury production process, and because the technical indicators of the equipment in the prior art are difficult to overcome the outward leakage of mercury vapor, and thus Mercury is emitted in the environment, which not only causes environmental pollution, but also reduces the recovery rate of mercury; at the same time, the traditional distillation equipment conducts distillation treatment, which makes the mercury-containing material unevenly heated, and then part of the mercury in the distillate is eliminated. The distillation is over, but some mercury-containing materials are still mixed in it, which leads to longer distillation time and higher preparation costs. In the process of discharging the distillation waste residue, the mercury-containing materials are not completely distilled due to uneven heating, and then During the discharge, some mercury-containing materials are discharged, which reduces the recovery rate of mercury and pollutes the environment, which makes it difficult for the existing mercury production process to overcome the problem of mercury in the discharged waste residue, waste gas and waste liquid. The content reaches 1-2%, which leads to mercury pollution to the greatest extent

Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 As shown, a gas energy-saving mercury distillation furnace is composed of a step 5, a distillation chamber arranged on the step 5 and a waste collection part arranged under the step 5.

[0028] Described distillation furnace chamber, it is made up of furnace wall 2 and the material inlet 11 at the top of distillation furnace chamber, and the cover plate 14 that can coincide with material inlet 11, the oxygen supply pipe 4 that is arranged on the bottom of furnace wall 2 and gas inlet 9. The distillation tube 3 is vertically arranged inside the furnace wall 2. A combustion chamber is formed between the distillation pipe 3 and the furnace wall 2. The oxygen supply pipe 4 and the gas inlet 9 communicate with the combustion chamber; the furnace wall 2 is close to the material inlet 11 Tail gas outlet 10 and mercury vapor outlet 1 are arranged at the place, wherein tail gas outlet 10 is communicated with combustion chamber; The top o...

Embodiment 2

[0049] A method for preparing a gas energy-saving mercury distillation furnace, comprising the following steps:

[0050] (1) Preparation of the aggregate warehouse: Use bricks to build a double-layer wall according to the method of building a wall, and open a door at a certain part of the aggregate warehouse. The door width is 3-5m, and the door height is 1-2m. The door is welded and inlaid with steel plates to form a door frame. The thickness of the steel plate is 10-20mm, the width of the steel plate is 20-30mm, and the thickness of the steel plate embedded in the wall is half of the thickness of the steel plate; Cover the upper part of the wall with steps, and the thickness of the steps is set to 15-20cm. The steps are made of concrete pouring, and the outermost edge of the steps is wider than the outermost edge of the aggregate warehouse;

[0051] (2) Preparation of the distillation furnace chamber: after the preparation of the steps is completed, the distillation furnace ...

Embodiment 3

[0054] In the process of mercury distillation treatment using the gas energy-saving mercury distillation furnace prepared in Example 1 or Example 2, the mercury-containing and processed material is added to the distillation tube through the material inlet, so that the distillation tube reaches the point where the mercury vapor is collected. The materials in the cavity are all filled, and then the cover plate 14 is covered on the material inlet, and then through the gas inlet and the oxygen supply pipe in the combustion chamber of the distillation furnace, the gas is burned in the combustion chamber, thereby achieving The distillation treatment of the mercury-containing material in the distillation pipe 3 makes the mercury volatilize into the mercury vapor collection chamber in the form of steam, and is discharged from the distillation furnace through the mercury vapor outlet and sent to be cooled and collected; and the residue material after the distillation is completed Throug...

Abstract

The invention relates to the technical field of mercury distillation furnaces, in particular to a gas energy-saving mercury distillation furnace and a manufacturing method thereof. The gas energy-saving mercury distillation furnace is formed by a step, a distillation cavity which is arranged in the step and a garbage collection part which is arranged under the step; mercury-containing materials are uniformly heated in the distillation processing process; in the process that mercury vapor which is formed by distillation goes up from the inside of distillation tubes to a mercury vapor collection cavity, heat exchange is carried out between the materials and the mercury vapor, so that the materials are preheated; meanwhile, the mercury vapor is cooled to a certain degree, so that the cost of subsequent mercury vapor cooling treatment is reduced, the cooling treatment period is shortened, the energy consumption is reduced, and the cost is saved; and the mercury vapor is prevented from being leaked and polluted by impurities, so that the environment pollution rate is reduced, and the quality of the mercury vapor is improved.
