TX-GF-JH-6 type boron trichloride and boron hexafluoride exhaust-gas purification absorbent

Abstract

The invention belongs to the technical field of exhaust-gas purification and discloses a TX-GF-JH-6 type boron trichloride and boron hexafluoride exhaust-gas purification absorbent. The TX-GF-JH-6 type boron trichloride and boron hexafluoride exhaust-gas purification absorbent comprises, by weight, 70% of strontium hydroxide, 28% of calcium hydroxide and 2% of epoxy resin. The method includes the steps of S1, selection of raw materials; S2, smashing and vibration mill; S3, raw material weighing; S4, kneading; S5, extrusion; S6, drying; S7, capability test; S8, product packing. The TX-GF-JH-6 type boron trichloride and boron hexafluoride exhaust-gas purification absorbent is simple in formula, chemical adsorption is derived from traditional physical adsorption of activated carbon, and harmless calcium salt, inorganic salt and the like which are stable are generated after adsorption reaction with corresponding gases; the absorbent can be directly used in road repairing, pit filling, refuse dumping and the like, secondary pollution cannot caused, simpleness in production technology is achieved, and effect can be well achieved.

technical field [0001] The invention relates to the technical field of waste gas purification, in particular to a TX-GF-JH-6 boron trichloride and boron hexafluoride waste gas purification adsorbent. Background technique [0002] With the improvement of environmental protection requirements, the harmful waste gas produced by industrial production must be treated to meet the standard before it can be discharged. At present, the country's emission standards for gases have been repeatedly raised. The water spray gas treatment system on the market is not efficient enough, and the second is in the north. When the temperature is low in winter, the water will freeze and cannot be used; and activated carbon is physical adsorption and the adsorption efficiency is also limited. Therefore, a new type of dry gas purification adsorbent is developed for the defects and deficiencies of activated carbon adsorbents in engineering applications. , because the adsorbent directly participates in...

Problems solved by technology

[0002] With the improvement of environmental protection requirements, the harmful waste gas produced by industrial production must be treated to meet the standard before it can be discharged. At present, the country's emission standards for gases have been repeatedly raised. The water spray gas treatment system on the market is not efficient enough, and the second is in the north. When the temperature is low in winter, the water will freeze and cannot be used; and activated carbon is physical adsorption and the adsorption efficiency is also limited. Therefore, a new type of dry gas purification adsorbent is developed for the defects and deficiencies of activated carbon adsorbents in engineering applications. , the purification efficiency of this adsorbent can basically reach more than 95% or even higher because it directly participates in the chemical reaction with the gas

[0003] Disadvantages and deficiencies of activated carbon adsorption: 1. Activated carbon adsorption is physical adsorption, which only adsorbs harmful gases on its surface, and no chemical reaction occurs inside; 2. Activated carbon is limited by temperature during use. If it is in summer or other specific circumstances, adsorption If the temperature in the box cannot be dissipated in time and the internal temperature is too high, there may be a risk of fire; 3. After the activated carbon is saturated, if it is not replaced in time, harmful gases will slowly accumulate and the concentration will become very high. Part of the harmful gases will be decomposed during replacement , escape, may bring life danger to the construction workers on site, etc. TX-GF-JH 6 type adsorbent is a new type of adsorbent developed based on the principle of neutralization reaction between acid gas and alkali. Activated carbon physical adsorption is extended to chemical adsorption, which generates stable harmless calcium salts, inorganic salts, etc. after adsorption and reaction with corresponding gases; it can be directly used for road construction, pit filling, landfill, etc., so that no secondary pollution will be generated. Therefore, there is an urgent need for a TX-GF-JH-6 type boron trichloride, boron hexafluoride waste gas purification adsorbent
