Problems solved by technology

[0012] Although with the development of fine chemical technology, rapid progress has been made in chemical dust suppressants, but there are still disadvantages such as high price or toxicological characteristics, corrosion, secondary pollution and refractory properties.
Moreover, the above dust suppressants are all used in mine dust, coal dust or road dust, etc., and there are no reports on the application of dust control in garbage

Embodiment 1

[0041] Example 1: Used in garbage transportation process

[0042] Take carboxymethyl cellulose (weight average molecular weight: 156,000, degree of substitution: 0.92) 5.0 kg, polyethylene glycol (weight average molecular weight: 400) 1.5 kg, sodium silicate 3.0 kg, mix in a mixer and add water 90.5kg, fully stirred at room temperature for 10-15 minutes, it is the finished product.

[0043] Acute skin irritation / corrosion tests were conducted according to the "Technical Specifications for the Identification of Chemical Toxicity" of the Ministry of Health. The test results showed that the irritation intensity was zero, which was non-irritating. According to the "Chemical Testing Guidelines" (HJ / T153-2004) acute oral toxicity test method, the test of the bacteriostatic agent's acute oral toxicity (LD 50 ): male rat> 4500mg / kg, female rat> 4500mg / kg. According to the "Guidelines for the Hazard Assessment of New Chemical Substances" (HJ / T154-2004), the oral acute toxicity classificati...

Embodiment 2

[0048] Example 2: Used in garbage loading and unloading process

[0049] Take 1.0 kg of carboxymethyl cellulose (weight average molecular weight: 145,000, degree of substitution: 0.90), polyethylene glycol 0.5 kg (weight average molecular weight: 300), and 5.0 kg of sodium silicate, and add water after mixing in a mixer 93.5kg, fully stirred at room temperature for 10-15 minutes, it is the finished product.

[0050] Acute skin irritation / corrosion tests were conducted according to the "Technical Specifications for the Identification of Chemical Toxicity" of the Ministry of Health. The test results showed that the irritation intensity was zero, which was non-irritating. According to the "Chemical Testing Guidelines" (HJ / T153-2004) acute oral toxicity test method, the test of the bacteriostatic agent's acute oral toxicity (LD 50 ): male rat> 4500mg / kg, female rat> 4500mg / kg. According to the "Guidelines for the Hazard Assessment of New Chemical Substances" (HJ / T154-2004), the oral a...

Embodiment 3

[0055] Example 3: Used in the garbage dumping process

[0056] Take 6.0 kg of carboxymethyl cellulose (weight average molecular weight: 123,000 degree of substitution: 0.88), polyethylene glycol 1.0 kg (weight average molecular weight: 400), 1.5 kg of sodium silicate, mix in a mixer and add water 91.5 kg, fully stirred at room temperature for 10-15 minutes, it is the finished product.

[0057] Acute skin irritation / corrosion tests were conducted according to the "Technical Specifications for the Identification of Chemical Toxicity" of the Ministry of Health. The test results showed that the irritation intensity was zero, which was non-irritating. According to the "Chemical Testing Guidelines" (HJ / T153-2004) acute oral toxicity test method, the test of the bacteriostatic agent's acute oral toxicity (LD 50 ): male rat> 4500mg / kg, female rat> 4500mg / kg.

Abstract

The invention relates to an inhibiting agent for controlling the dust pollution during the household garbage collection and transportation process, preparation and applications thereof. The inhibiting agent is a uniform solution taking water as the solvent, and comprises solutes of carboxymethyl cellulose (CMC), polyethylene glycol, and sodium silicate. The inhibiting agent is nontoxic, harmless, noncorrosive, safe, and environment-friendly, can effectively control the garbage dust emission, and is capable of inhibiting dust emission for a long time through the wetting and coagulation effect. The inhibiting agent can be used through a spray mode, and the operation is simple and convenient. Moreover, the dusts and floating substances in the air can be effectively absorbed, and thus the garbage dust emission is effectively avoided.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an inhibitor for controlling dust pollution during the collection and transportation of domestic garbage, and its preparation and application. Background technique [0002] The transfer process of domestic waste, including waste loading and unloading process, temporary landing storage point and vehicle removal and transportation process, is often accompanied by dust pollution. Although airtight equipment is considered, there are still dust scattering or secondary dust problems. Therefore, the dust suppressant to control the dust emission during the garbage collection and transportation needs to be solved urgently. [0003] Inhibitor (dust suppressor) technology originated in the 1940s. The United Kingdom used derivatives of sulfonated hydrocarbons as wetting agents to suppress dust accumulation on roadway floor and coal dust during blasting operations. After...
