High-temperature salt deposition resisting agent

Abstract

The invention provides a high-temperature salt deposition resisting agent which is prepared from the following components in parts by weight: 10 to 30 percent of ATMP, 15 to 30 percent of HEDP , 0 to 20 percent of EDTMPS, 0 to 15 percent of EDTMPA, 10 to 15 percent of DTPMPA, 0 to 5 percent of TH-904, 5 to 20 percent of PESA and 5 to 25 percent of PASP. Compared with the effect that the salt-containing wastewater is sprayed back to a quench tower, after the agent is added, the salt of the salt-containing waste liquid is obviously fluffy and easy to fall, the start-up period of the device is prolonged by about 120 days, and after the agent-free salt-containing waste liquid is sprayed back, the quench tower is blocked and bridged, the operation period of the device is shortened, and the device is blocked after about one week and is stopped for cleaning.

Description

technical field [0001] The invention belongs to the field of water treatment in the hazardous waste industry, and specifically relates to a high-temperature anti-salt agent. Background technique [0002] It is still difficult to count the amount of such transboundary transfer of hazardous waste, but it is clearly growing. According to a survey report by Greenpeace, developed countries are transshipping hazardous waste to developing countries at an annual scale of 50 million tons, from 1986 to In 1992, developed countries transferred a total of 163 million tons of hazardous waste to developing countries and Eastern European countries. The transboundary transfer of hazardous waste to developing countries and even the global environment has non-negligible harm. Basically, they lack the technical means and economic capacity to deal with and dispose of hazardous waste. The import of hazardous waste will inevitably cause damage to the local ecological environment and human health....

[0002] It is still difficult to count the amount of such transboundary transfer of hazardous waste, but it is clearly growing. According to a survey report by Greenpeace, developed countries are transshipping hazardous waste to developing countries at an annual scale of 50 million tons, from 1986 to In 1992, developed countries transferred a total of 163 million tons of hazardous waste to developing countries and Eastern European countries. The transboundary transfer of hazardous waste to developing countries and even the global environment has non-negligible harm. Basically, they lack the technical means and economic capacity to deal with and dispose of hazardous waste. The import of hazardous waste will inevitably cause damage to the local ecological environment and human health. Secondly, the spread of hazardous waste to underdeveloped areas is actually to evade the regulations of the country. Disposal responsibility, so that hazardous wastes are not properly treated and disposed of and spread into the environment. The result of long-term accumulation will inevitably cause harm to the global environment. Entering under cover, the importer is to gain economic benefits, regardless of its possible impact on the environment and human health, so they cannot get proper treatment and disposal. The transboundary movement of hazardous waste has become a serious global environmental problem. One, if no measures are taken to control it, it is bound to cause serious harm to the global environment

[0003] Existing hazardous waste, especially liquid hazardous waste (salt-containing waste liquid), is currently only through incineration, physical and chemical processes, and waste liquid disposal cannot be effectively and reasonably treated and disposed of. Adding high-temperature salt-resistant agents to salt-containing waste liquid can Spray the salty waste liquid back into the quench tower to effectively treat the salty waste liquid
