Abstract
The utility model discloses a sludge indirect drying and incinerating subsystem. The sludge indirect drying and incinerating subsystem is characterized in that a heating medium outlet of a heating medium high level tank (1) is connected with an inlet of a heating medium circulation pump (2), an outlet of the heating medium circulation pump (2) is connected to a waste heat boiler (3) and then is further connected to a heating medium inlet of a sludge indirect drying machine (4), a heating medium outlet of the sludge indirect drying machine (4) is connected to the heating medium high level tank (1), and a moisture outlet of the sludge indirect drying machine (4) is connected to a heat pump evaporator (6) through a moisture-venting fan (5), wherein an air outlet is arranged on the top of the heat pump evaporator (6) and a condensate water outlet is arranged at the bottom of the heat pump evaporator (6). The sludge indirect drying and incinerating subsystem utilizes a heat pump to cool down and dehydrate moisture. Non-condensable gas is transported into a sludge incinerator to be incinerated and deodorized. The heat pump transfers the heating medium dried indirectly by preheated sludge using the heat released during the moisture cooling process. The sludge indirect drying and incinerating subsystem has the advantages of avoiding heat loss of a large amount of high temperature smoke discharge caused by direct incineration of the moisture, and maintaining the original heat balance of an incinerator to the best.
Description
Technical field
The utility model belongs to the ﹠ Mud technical field, specifically a kind of sludge drying, sludge incineration is assembled organic integrated device.
Background technology
Adopt sludge high-drying dehydration, contact drying, burn the United Technologies disposing sludge, can make the whole carbonizations of organism, pathogen kill, to greatest extent reduce mud volume.
In the mud contact drying process, can produce the moisture that contains a large amount of water vapour with strong odor.The not treated direct discharging of this moisture can make surrounding environment produce unpleasant odour.As send into the sludge incinerator deodorization by incineration, and then can cause high-temperature flue gas to discharge excessive thermosteresis, may destroy burning thermal equilibrium thus, the situation that originally can rely on mud self-heating amount to burn is changed into must add auxiliary fuel and just can be kept burning.
Summary of the invention
The purpose of this utility model is exactly the problem for above-mentioned existence, provides one not destroy the original thermal equilibrium of incinerator, and Btu utilization is abundant, and is dry between the little mud of thermosteresis, burn subsystem.
The technical solution adopted in the utility model is as follows:
A kind of mud contact drying, burning subsystem, it is characterized in that it comprises the heating agent header box, the heating agent outlet of heating agent header box connects the import of heat medium circulation pump, the outlet of heat medium circulation pump is connected to the heating agent import that is connected to again mud contact drying machine behind the waste heat boiler, the heating agent outlet of mud contact drying machine is connected to described heating agent header box, the moisture outlet of described mud contact drying machine is connected to evaporator with heat pump by wet-emitting blower, the top of described evaporator with heat pump is provided with venting port, and its bottom is provided with condensed water discharge outlet.
The outlet of described heat medium circulation pump is connected to first heat pump condenser and connects waste heat boiler again.
The condensed water discharge outlet of described evaporator with heat pump bottom is connected with syphon trap.
The beneficial effects of the utility model have:
Utilize heat pump with the moisture cooled dehydrated, non-condensable gas send the sludge incinerator deodorization by incineration, heat pump cools off moisture again liberated heat and shifts the heating agent that preheats the mud contact drying, avoid moisture directly to burn the high-temperature flue gas that causes and discharged excessive thermosteresis, do not destroyed as far as possible the original thermal equilibrium of incinerator.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the heating agent outlet of the utility model heating agent header box 1 connects the import of heat medium circulation pump 2, the outlet of heat medium circulation pump 2 connects and is connected to the heating agent import that is connected to again mud contact drying machine 4 behind the waste heat boiler 3 behind the heat pump condenser 7 again, and the heating agent outlet of mud contact drying machine 4 is connected to heating agent header box 1.The moisture outlet of mud contact drying machine 4 is connected to evaporator with heat pump 6 by wet-emitting blower 5.The top of evaporator with heat pump 6 is provided with venting port, and the non-condensable gas after the decrement significantly of dewatering send the sludge incinerator deodorization by incineration.Humid water vapor condensation becomes condensed water to drain into Sewage Plant from the condensed water discharge outlet of evaporator with heat pump 6 bottoms to process again.The condensed water discharge outlet of evaporator with heat pump 6 bottoms is connected with syphon trap 8, and the water seal effect is that condensate drain bears water Shi Buhui and causes moisture to leak.
Carry out heat, wet two kinds of exchange processs at evaporator with heat pump 6 interior heat-conducting mediums and moisture by heat exchange surface, existing Exchange of apparent heat has again the latent heat exchange.The cooling power of evaporator with heat pump 6 has direct relation with the ratio enthalpy of moisture.Adopt straight large cover sheet mode to manufacture and design evaporator with heat pump 6 by calculating heat flux.The structure formation of vaporizer is: vaporizer is arranged in the shell internal upper part, and moisture enters from the shell middle part, upwards flows through vaporizer, and not solidifying foul smell flows out from vaporizer top, sends into the sludge incinerator deodorization by incineration.Condensed water collects in downwards in the interior water leg of shell, discharges by syphon trap, flows into Sewage treatment systems and processes.
Working process of the present utility model is as follows:
The moisture that mud contact drying machine 4 produces is transported to evaporator with heat pump 6 by wet-emitting blower 5, the heat pump heat-conducting medium is drawn the moisture heat in evaporative process, make moisture cooling, humid water vapor condensation becomes condensed water, and the non-condensable gas after the decrement significantly of dewatering send the sludge incinerator deodorization by incineration.In heat pump condenser 7, the heat pump heat-conducting medium will shift (drawing the heat of the moisture) heat that comes and emit and preheat mud contact drying heating agent in condensation process.
The mud contact drying adopts the heating agent Recycle design, and heating agent relies on gravity to flow into heat medium circulation pump 2 imports from heating agent header box 1.Heat medium circulation pump 2 is sent heating agent into first heat pump condenser, heating agent preheats, heating agent after the preheating enters waste heat boiler 3(again and utilizes sludge incinerator sludge incineration waste heat) further heat temperature raising, the heating agent after the intensification flows into 4 heating of mud contact drying machine, sludge-drying.Carry out indirect heat exchange with mud and fallen warm heating agent and flow back to again heating agent header box 1, so circulation.
The utility model calculates heat according to the dry amount of moisture that produces of mud indirect heating, water vapour content, moisture temperature and condensing temperature.According to the heat pump that calculates heat and select close specified heating (cold) amount, and carry out system design by the related specifications requirement.
Other undeclared part that the utility model relates to is same as the prior art.
