Abstract
The utility model relates to a copolymerization is sludge drying device for formaldehyde production, the cofferdam that sets up around closed box and closed box upper surface is equipped with the baffle in the middle part of the front and back of closed box, two regions about the baffle divide into the closed box are equipped with the through -hole on the baffle, be equipped with hot water input pipeline on the up end in the left side region of closed box, be equipped with hot water output pipeline on the preceding terminal surface in the right side region of closed box, all be equipped with the valve on hot water input pipeline and the hot water output pipeline. This structure can be filled the low pressure steam who utilizes copolymerization formaldehyde production process to produce and is carried out drying as dry heat source to mud with the latent heat energy of reboiler steam condensate and heat, the energy saving, and the dry sludge calorific value of make full use of, reduction in production cost is favorable to reducing solid waste mud content in the environment moreover, protects natural environment.
Description
Technical field
The utility model belongs to polyoxymethylene plant-scale equipment technical field, is specifically related to a kind of copolymerized methanal production sludge drying mechanism.
Background technology
In the treating processes of Industrial Wastewater Treatment, municipal effluent and industrial sludge, the sludge quantity produced accounts for 0.3% ~ 0.5% of total treatment capacity, moreover sludge components is complicated, containing parasitic ovum, heavy metal and pathogenic micro-organism etc., must process, just can prevent from causing secondary pollution to environment.
Giving in water and wastewater treatment, all kinds of throw outs, floating matter etc. that different treatment process produces are referred to as mud.The composition of mud, character depend primarily on the composition, character and the treatment process that process water, and its composition is very complicated, has varied sorting technique, and has different titles.Precipitating sludge can be divided into as physical sedimentation mud, coagulate sludge, chemical sludge and the mud that produces in secondary treatment process as sewage of biological treatment mud according to mud sepn process from water, comprise humus sludge that the method such as biological filter, blodisc obtains and the active sludge that activated sludge process obtains; Organic sludge and inorganic mud can be divided into by sludge components and character.
At present the mud of a large amount of non-stabilizing treatment has become sewage work's white elephant, and mud that is how that output is huge, complicated component carries out properly processing safely, make that it is innoxious, resource utilization, minimizing, paid close attention to widely.The measurement result display of sludge components, containing a large amount of organic substances in mud, which illustrating organic content higher in mud makes mud have available calorific value, this has established the potential value basis that mud has recycling, also just determines the possibility of sewage sludge harmlessness and recycling treatment.The primary condition of mud contribution calorific value is, the water ratio of mud must from sewage work out time about 90% be down to less than 30%, in other words to mud carry out deep dehydration become mud can by the key problem in technology of recycling.Along with scientific-technical progress, China will release process disposal options more effectively and reasonably, and the priority of sludge treatment subtracts appearance, utilization, discarded, should become the main flow of sludge treatment after sludge reduction, stabilization, harmless treatment as resource reusing.
The measurement result display of sludge components, copolymerized methanal production process produces in sewage containing organic matters such as formaldehyde, methyl alcohol, benzene, ethylene glycol, dioxolane, trioxymethylene, formic acid, methyl-formiate, paraformaldehydes, according to the correlation analysis between mud organic matter and calorific value, the mean calorie of mud is produced between 3000 ~ 4000Kcal/kg in copolymerized methanal production process, which illustrating organic content higher in mud makes mud have available calorific value, and this calorific value just copolymerized methanal manufacture mud has the value place of resourcebility recycling; Mix in bunker coal after drying sludge and enter boiler combustion, achieve the recycling of mud in process of producing polyformaldehyde.
There is a lot of pyroprocess in industrial enterprise, the used heat that after production process completes, residue is a large amount of, if recycled, production cost can significantly decline.Along with the development of waste heat recovery technology, be originally considered to reclaim or to be unworthy that the heat reclaimed can be recycled economically.In copolymerized methanal production process, recuperable used heat may have the following aspects: low-pressure steam, interchanger cooling backwater, steam condensate etc.
Utility model content
For overcoming Problems existing in production, the purpose of this utility model is to provide a kind of copolymerized methanal production sludge drying mechanism, this device can fill the low-pressure steam that utilizes copolymerized methanal production process to produce and the potential heat energy of interchanger cooling backwater carries out dry heat as drying source to mud, save energy, reduces production cost.
For achieving the above object, the technical scheme taked of the utility model is as follows:
The utility model provides a kind of copolymerized methanal production sludge drying mechanism, comprise the cofferdam of closed box and the setting of closed box upper surface surrounding, in the middle part of the front and back of closed box, be provided with dividing plate, closed box is divided into two regions, left and right by dividing plate, and dividing plate is provided with through hole; The upper surface of the left field of described closed box is provided with hot water input channel, and the front end face of the right side area of closed box is provided with hot water delivery pipe road, and hot water input channel and hot water delivery pipe road are equipped with valve.
According to above-mentioned copolymerized methanal production sludge drying mechanism, also comprise mechanism of keeping off the rain, described in mechanism of keeping off the rain be made up of column and rain shade, on four angles of enclosure wall, be respectively arranged with column, the top of column is provided with rain shade.
According to above-mentioned copolymerized methanal production sludge drying mechanism, also comprise four hangers, four hangers are symmetricly set on the left and right sides of closed box.
