Problems solved by technology

[0003] The existing sludge harmless treatment device has unreasonable design and old-fashioned structure, and cannot use the biogas generated during the harmless treatment of sludge for its own use, which not only makes the treatment efficiency of sludge lower, but also It also makes the cost of harmless treatment of sludge higher, and it is easy to discharge active microorganisms and various germs during the treatment process to cause harm to the external environment, and it is easy to cause insufficient sludge treatment, resulting in poor treatment quality. Poor, low environmental protection value. At the same time, the existing sludge harmless treatment device is easy to be blocked during use, and cannot discharge the harmless treated sludge smoothly. In addition, the existing sludge Harmless treatment device, its interior is easy to affect the use due to the adhesion of a large amount of sludge

Embodiment 1

[0047] A sludge harmless treatment device, such as figure 1 As shown, it includes a bottom fixed unit 1, and also includes a sludge harmless treatment unit 2, a gas storage unit 3, and a combustion heating unit 4, and the sludge harmless treatment unit 2 is fixedly installed on the bottom fixed unit 1 , the gas storage unit 3 is connected to the sludge harmless treatment unit 2, the combustion heating unit 4 is connected to the gas storage unit 3, and the combustion heating unit 4 is fixedly installed on the bottom Bottom interior of fixed unit 1.

[0048] By adopting the above technical scheme, the bottom fixed unit 1 is used to install the sludge harmless treatment unit 2 and the combustion heating unit 4; the sludge harmless treatment unit 2 is used to perform harmless anaerobic fermentation treatment on the sludge, so that The organic matter in the sludge (such as human, livestock and poultry manure, straw, weeds, etc.) is decomposed and metabolized by various microorgani...

Embodiment 2

[0069] The difference from Example 1 is that a protective layer is also provided on the inner surface of the tank body 7, and the protective layer is prepared by the following method:

[0070] Take the following raw materials and weigh them by weight: 20-30 parts of epoxy resin, 8-12 parts of calcium carbonate powder, 10-12 parts of titanium dioxide powder, 14-18 parts of phenolic resin, 13-15 parts of aluminum oxide powder, 15-18 parts of tetrafluoroethylene, 12-14 parts of acrylic emulsion, 3-5 parts of alcohol ester dodecane, 3-5 parts of triethanolamine, 2-4 parts of emulsified silicone oil and 30-50 parts of water;

[0071] S1. Add the weighed acrylic emulsion, alcohol ester dodeca, triethanolamine, emulsified silicone oil and water into the mixer and stir for 20-30min at a stirring speed of 500-700r / min to prepare a mixed solution;

[0072] S2. Adding epoxy resin, calcium carbonate powder, titanium dioxide powder, phenolic resin, aluminum oxide powder and polytetrafluoro...

Abstract

The invention discloses a harmless treatment device for sludge. The device comprises a bottom fixing unit, and further comprises a harmless sludge treatment unit, a gas storage unit and a combustion heating unit, the harmless sludge treatment unit is fixedly mounted on the bottom fixing unit, the gas storage unit is communicated with the harmless sludge treatment unit, the combustion heating unitis communicated with the gas storage unit, and the combustion heating unit is fixedly mounted inside the bottom of the bottom fixing unit. The device has the advantages of reasonable design, novel structure, achieving the effects of effectively increasing the sludge treatment efficiency and effectively reducing the harmless treatment cost of sludge by effectively using biogas generated in the harmless treatment process of the sludge for self use, no generation or discharge of toxic and harmful substances in the treatment process, good treatment quality, high environmental protection values, non-blockage, smoothness in discharge of harmlessly treated sludge, and avoiding of adhesion of a large amount of sludge in the device on use.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, more specifically, it relates to a sludge harmless treatment device. Background technique [0002] Municipal sludge refers to the solid waste generated during the treatment of urban domestic sewage and industrial wastewater. The sludge contains toxic and harmful substances such as heavy metals, pathogenic bacteria and parasite eggs. With the development of urban industry and economy, the amount of sludge has increased sharply, and improper disposal may cause serious damage to the ecological environment and human health. Since the heavy metals, pathogenic organisms and microorganisms in sludge have certain activity and poisonous effect, stability and harmlessness are the basis of sludge land use. The purpose of sludge harmless treatment is to further reduce the water content of sludge, kill bacteria and pathogens in sludge, eliminate odor, degrade organic matter in sludge, reduce the co...
