Mercury is noxious material, can lead to brain and hepatic injury after oral, sucking or contact, as the understanding endangered mercury is increasing,
The method that people are sought for processing mercury metal waste material.
Wherein handling the most common method of mercurous waste material is to generate the chemical methodes such as HgS with S and Hg.These methods are by amalgamation
At compound containing mercury, then mercury compound is decomposed again and extracts mercury metal, consumes more reductant-oxidant, catalysis in whole process
Agent etc., and chemical waste can be generated, cause environmental pollution.
China application patent of invention CN204816147U discloses a kind of mercury recyclable device that mercury is recycled from containing mercuryvapour,
It first passes through smelting furnace and obtains mercury vapour, then obtain mercury using multistage cooling, wherein joined gas circulation in favor of the conveying of mercury,
The mercury that filtering tank absorption can be mitigated by way of condensing again after pressurization extends the period that agent is changed in its failure, the utility model
Realize pernicious gas zero-emission, however its at least there are the following problems:
(1) the utility model is provided with two air bags and removes balance system pressure, however is provided with air-introduced machine in gas circulation
With two gas transmission devices of air compressor, but whole system pressure balance is still difficult, complicated for operation.
(2) smelting furnace needs to be heated at high temperature, and the high temperature mercury vapour of generation is cooling further through circulation cooling device, heating,
Cooling consumes the energy respectively, and comprehensive utilization rate of energy source is low.
(3) solid waste is heated at high temperature in smelting furnace, is inevitably crushed and generates dust, and dust is easily adsorbed on and sets
Cause to block in standby, pipeline, when be adsorbed on also resulted in heat exchanger heat transfer effect be deteriorated, cooling temperature is not achieved, threaten
The normal work of air compressor, it is difficult to long-period stable operation.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of easy to operate, comprehensive utilization of energy rate it is high and
Eliminate the collection and treatment device for the mercury metal that dust influences.
The utility model solves technical solution provided by above-mentioned technical problem:
A kind of collection and treatment device of mercury metal, including sequentially connected smelting furnace, heat exchanger, bucket trap, filtering tank, gas
Gas compressor, the gas compressor outlet are connected to smelting furnace, form a gas circulation loop；The bucket trap and filtering
Pot bottom is connected to storage mercury tank, dust collector is provided between the smelting furnace and heat exchanger, for removing powder in gas
Dirt avoids blocking pipeline, equipment；It is provided with subcolling condenser between the heat exchanger and bucket trap, deep temperature reduction is used for, passes through
Low temperature can be such that the mercury vapour carried secretly in gas condenses；The dust collector outlet is connected to the tube side of heat exchanger, the gas
Gas compressor outlet is connected to the shell side of heat exchanger, and the shell-side outlet of the heat exchanger is connected to smelting furnace, by melting outlet of still
The gas of gas and smelting furnace entrance exchange heat, this is conducive to sufficiently recycle heat, realizes the comprehensive utilization of the energy, described
Gas heater is additionally provided between gas compressor outlet and smelting furnace.
Further, the dust collector outlet can also be connected to the shell side of heat exchanger, at this time the gas compressor
Outlet is connected to the tube side of heat exchanger.
Further, gas compressor outlet setting gas heater can be located at gas compressor outlet with heat exchanger it
Between, also can be set between heat exchanger exit and smelting furnace entrance, preferably gas heater be set to heat exchanger exit with
Between smelting furnace entrance.
Further, the subcolling condenser is ammonia machine.
Further, it is filled with sulfur loading active carbon in the filtering tank, is used for depth demercuration.
The working principle of the present apparatus is as follows:
High temperature in melting is by the mercury thermal conversion in solid waste at mercury vapour, and mercury vapour is under the carrying of circulating air
It sequentially enters dust collector and gives smelting furnace entrance circulating air except the dust of deentrainment, into heat exchanger lowered temperature reclamation partial heat
Body, further cool down into subcolling condenser, the mercury solution body that condensation is got off separates in bucket trap with gas, at the top of bucket trap
Gas successively removes the Trace Mercury of entrainment through filtering tank again, gas compressor is pressurized, heat exchanger recycles smelting furnace exit gas
Enter smelting furnace after heat, gas heater heating, bucket trap and the liquid mercury for filtering pot bottom then enter holding vessel storage.
Beneficial effect
(1) for multi-component material, be all conducive to heavy constituent therein (the higher component of boiling point) by being pressurized or cooling down
Condensation, the utility model are provided with subcolling condenser, promote mercury condensing recovery in bucket trap by low temperature, realize higher
The rate of recovery of mercury, it is same to alleviate the demercuration load of filtering tank, therefore a gas is provided only in the gas-circulating system of the present apparatus
Gas compressor is as power-equipment, and easy to operate, pressure control is stablized.
(2) it by the way that the pipe of heat exchanger, shell side to be connected to the import and export of smelting furnace respectively, has effectively recycled smelting furnace and has gone out
The heat of gas reduces the energy consumption of device.
(3) it is exported between heat exchanger in melting value and is provided with dust collector, avoided dust and deposited in heat exchanger
Equipment blocking, heat transfer effect is led to problems such as to be deteriorated.
(4) in cyclic process, gas passes through entire solid waste bed, is conducive in time carry the mercury vapour in solid waste
Out.
