Abstract
The invention discloses a short-flow and high-difficulty wastewater treatment device. The device is characterized by comprising a waste heat water tank, wherein a waste heat exchanger is arranged in the waste heat water tank; the bottom of the waste heat water tank is connected with the inlet of a waste heat water circulating pump through a pipeline; the outlet of the waste heat water circulating pump is connected to the upper end of an evaporation plate through a pipeline; the evaporation plate is positioned in a condensation plate or a condensation tube and spaced from the inner wall of the condensation plate or the condensation tube in certain distance; a circulating cooling water return jacket is arranged on the outer wall of the condensation plate or the condensation tube; the bottom of the evaporation plate is respectively connected to the waste heat water tank and a concentrate outlet pipe through pipelines; and the bottom of the condensation plate or the condensation tube is connected with a condensed water outlet pipe. The device is simple in structure and practical; wastewater is indirectly heated by using low-quality waste heat in an enterprise, so that the thermal wastewater is evaporated at a low temperature in the device; and the device is low in investment and low in running cost and can economically and thoroughly treat the high-difficulty wastewater, and the quality of the discharged water can reach a high recycled water standard.
Description
Technical field
The present invention relates to technical field of waste water processing, specifically a kind of high density is difficult to the treatment unit of biochemical waste water.
Background technology
The high slat-containing wastewater that produces in the production processes such as chemical industry such as fuel, agricultural chemicals, medicine intermediate, the high-concentration emulsified liquid that mechanical workout produces; The high concentrated organic wastewater that industries such as papermaking, leather and food produce; This type of waste water is very big to environmental hazard, can make receiving water body anoxic even anaerobism, and most aquatic organisms are dead, thereby produces stench.This type of waste water contains a large amount of hazardous contaminants, can in physical environments such as water body, soil, constantly accumulate, store, and gets into human body at last, is detrimental to health.Also there are technological difficulties in processing to this type of waste water at present, is difficult to the low working cost of low investment and handles this type of waste water, makes it qualified discharge.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned prior art, provides a kind of simple in structure, less investment, the high-leveled and difficult wastewater treatment equipment of short flow process that working cost is low.
The technical scheme that the present invention adopts is following:
The high-leveled and difficult wastewater treatment equipment of a kind of short flow process; It is characterized in that it comprises the used heat water tank; Be provided with residual-heat exchanger in the used heat water tank, the bottom of used heat water tank is through pipe connection spent hot water inlet of circulating pump, and spent hot water's outlet of circulating pump is through the upper end of pipe connection to evaporation plate; Said evaporation plate be positioned at cold plate or prolong and with cold plate or prolong inwall at a distance of a segment distance; The outer wall of cold plate or prolong is provided with circulation cooling backwater chuck, and the bottom of said evaporation plate is connected to used heat water tank and liquid concentrator rising pipe respectively through pipeline, and the bottom of cold plate or prolong connects the water of condensation rising pipe.
Said cold plate or prolong are provided with two groups.
Said cold plate or prolong are obliquely installed.
The upper end of said circulation cooling backwater chuck links to each other with the water outlet of cooling water circulating pump.
Beneficial effect of the present invention has:
Simple and practical, utilize the various low-quality waste heat of enterprise, indirect heating waste water makes thermal wastewater low-temperature evaporation in device, less investment, running cost is low, and ability economy more thoroughly handled high-leveled and difficult waste water, makes effluent quality can reach higher reuse water standard.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further:
As shown in Figure 1, it includes used heat water tank 1 the present invention, is provided with residual-heat exchanger 2 in the used heat water tank 1, and residual-heat exchanger 2 can be to utilize waste water residual heat, also can be to utilize waste gas residual heat.The bottom of used heat water tank 1 is through the import of pipe connection spent hot water recycle pump 3, and the outlet of spent hot water's recycle pump 3 is through the upper end of pipe connection to evaporation plate 4.Evaporation plate 4 be positioned at cold plate or prolong 5 and with cold plate or prolong 5 inwalls at a distance of a segment distance, make it to have suitable mist vapour diffusion couple fluid space.Cold plate or prolong 5 inside are a sealed space, and the outer wall of cold plate or prolong 5 is provided with circulation cooling backwater chuck 6, and the upper end of circulation cooling backwater chuck 6 links to each other with the water outlet of cooling water circulating pump 8.The bottom of evaporation plate 4 is connected to used heat water tank 1 and liquid concentrator rising pipe 7 respectively through pipeline, and the bottom of cold plate or prolong 5 connects water of condensation rising pipe 9.
Cold plate or prolong 5 can be provided with many groups, generally are preferably two groups.Cold plate or prolong 5 are obliquely installed, and are convenient to sewage or flow of cooling water.
The present invention is following in working process:
Spent hot water's recycle pump 3 is with the upper end that is promoted to each unitary evaporation plate 4 by residual-heat exchanger 2 heating treatment sewages in the used heat water tank 1; Flow evaporation on evaporation plate 4; The mist vapour of evaporation is in the diffusion convection process; Meet be recycled in the cooling backwater chuck 6 recirculated cooling water refrigerative cold plate or prolong 5 after, be condensed into condensed water.Water of condensation flows down from cold plate or prolong 5 inwalls, is discharging or reuse water after the high-leveled and difficult wastewater treatment after the water of condensation rising pipe 9 that links to each other from cold plate or prolong 5 bottoms flows out and collects.The decrement raffinate otherwise processed of collecting from evaporation plate 4 bottoms is disposed or reuse.
The undeclared part of other that the present invention relates to is identical with prior art.
