The present invention relates to the field of environmental protection, and specifically relates to a treatment process for resource utilization of medical waste salt at medium temperature pyrolysis; the present invention provides a process for resource utilization of waste medical salt at medium temperature pyrolysis. The principle is to use lower temperature to fully oxidize and decompose organic pollutants from the waste salt that has removed volatile substances, so as to achieve the purpose of harmless treatment of waste salt and then resource utilization; the invention adds an inorganic salt anti-caking agent, It can effectively prevent the waste salt from agglomerating in the fluidized bed reactor and ensure the sufficient oxidation and decomposition of organic pollutants, which is the key to the process; the waste salt obtained by the treatment method of medical waste salt of the present invention has extremely low organic residues and no agglomeration phenomenon. The organic matter is fully oxidized, and the energy saving is significantly reduced. The effective treatment of medical waste salt can not only protect the environment, but also reuse the main component sodium chloride salt to make up for the market gap, which has high economic value.

The invention relates to a material mixing machine, in particular to a material mixing machine for rare earth ore powder and hydrochloric acid. The material mixing machine for the rare earth ore powder and the hydrochloric acid aims to achieve the technical effects that manual feeding of the hydrochloric acid is not needed, the decomposition rate can be improved, and waste of the hydrochloric acidis avoided. The material mixing machine for the rare earth ore powder and the hydrochloric acid comprises an installation frame, a box, a discharging pipe, a valve, a support rod, a servo motor, a sector gear and the like. The box is installed in the middle of the inner wall of the lower side of the installation frame. The discharging pipe is connected with the lower portion of the left wall of the box. The discharging pipe penetrates through the left portion of the lower wall of the installation frame. The material mixing machine for the rare earth ore powder and the hydrochloric acid achieves the technical effects that manual feeding of the hydrochloric acid is not needed, the decomposition rate can be improved, and waste of the hydrochloric acid is avoided. Through the arrangement of acylinder block and a piston, hydrochloric acid liquid flows into the box intermittently, so that the rare earth powder can be fully oxidized and decomposed, and the effect of improving the decomposing efficiency is achieved.

The invention discloses a high-flux super microwave digestion pretreatment method for analyzing multielement content of foods based on ICPMS and ICPOES. The microwave digestion pretreatment is carried out by low-acidity digestion solution on the basis of high-temperature resisting property of the super microwave, thus the reaction severity in the microwave digestion process is inhibited; the sample organic matter can be fully oxidized and decomposed under a high working temperature (220 DEG C), so that the stable digestion process can reach the digestion terminal, and clear and transparent digestion solution is obtained; meanwhile, before digestion, the sample fluid to be digested does not need to vortex vibrate or stay overnight, other reagent is not further added; moreover, the subsequent acid catching step of the digestion fluid is saved, the operation process is greatly simplified, the treatment efficiency is improved and the pollution is reduced; moreover, contents of multiple elements in different types of foods can be tested at the same time.

The invention discloses a 1,2-dichloropropane separation system and separation technique. The separation system comprises a bottom with vibration surge tanks and a top with a nozzle head, wherein a water channel is divided into the plurality of vibration surge tanks by the tank body. The separation technique is implemented in a way that: under the action of the vibration surge tanks, 1,2-dichloropropane-containing underground water flows according to a S-shaped route; the reflux quantity is controlled at 80 m<3> / minute, the water level is controlled at 80cm, the vibration surge period is controlled at 20 times / minute, and the vibration surge plate stroke is controlled at 600mm; and a continuous spray mode is adopted. The separation technique has the characteristics of high environment friendliness, high resource utilization ratio, high treatment effect and high impact resistance, and implements full-automatic control.

The invention discloses a smoldering type household waste incineration treatment device and a use method thereof. The smoldering type household waste incineration treatment device comprises an incinerator and a tail gas treatment device communicating with the incinerator. The smoldering type household waste incineration treatment device has the beneficial effects that by the matching of an inner incinerator body and an outer incinerator body, intermittent oxygen supply is adopted, and gas for sustained combustion can be accessed to the inner incinerator body simply when a through hole communicates with a feeding channel, an air inlet channel and a smoke vent, so that the combustion of the inner incinerator body is kept in a smothering stage, fuel consumption and the content of nitrogen oxide in flue gas are reduced; the inner incinerator body, at a set rotational speed, allows air to be fully contacted and mixed with waste and allows the air to be fully contacted and mixed with the flue gas and the disturbance is full, so that noxious substances are subjected to oxygenolysis in a short time; large grain impurities and an irritation smell in the exhausted flue gas are filtered through a filter screen and a deodorization layer, and finally the raising flue gas is subjected to spraying desulfurization by employing a spray head, thus dedusting, deodorization and desulfurization treatment on the flue gas are completed.
