Abstract

The utility model discloses a sewage heating device of a sewage plant, and relates to auxiliary equipment for sewage treatment. The heating device is characterized in that a sewage pump and a residue filter are additionally arranged at a water inlet of an original regulating tank, a triple-effect evaporator is additionally arranged in a production workshop, valves are disposed on the residue filter, the triple-effect evaporator arranged in the production workshop and the sewage pump arranged at the water inlet of the regulating tank, and the regulating tank, the sewage pump, the residue filter, the valves and the triple-effect evaporator are serially connected with one another by sewage pipelines to form a heating system for sewage flowing circularly. The sewage heating device has the advantages that steam which is a heat source for heating the sewage of the sewage plant is saved, resources are saved, consumption is reduced, loss of the water resources is avoided, the heating efficiency is greatly improved, and a sewage treatment effect of the sewage plant is guaranteed.

Description

Sewage plant sewage heat riser

Technical field

The utility model relates to a kind of sewage disposal utility appliance.

Background technology

Winter approached, decline along with external temperature, sewage temperature descends thereupon, and the adaptive temperature of sewage plant processing requirement sewage disposal is about 30 degree, if the bacterial classification of the too low sewage plant of temperature will lose activity, treatment effect will be affected, for satisfying processing requirement, must before sewage disposal, carry out waste water and heat up, wastewater temperature is remained on about 30 degree.

At present, existing waste water heat riser be utilize steam coil heated, be that steam carries out heat exchange by coil pipe and the waste water that arranges in the wastewater disposal basin, the defective of this heating installation is that the area of heat exchange is limited, and is static heating in large sewage lagoon, and the water yield is when many (surpassing 100 sides) in the pond, waste water heat temperature raising in the pond is slow, DeGrain simultaneously also so that the steam amount of expending is large, causes the rising of sewage disposal expense.

Summary of the invention

The purpose of this utility model provides a kind of sewage plant sewage heat riser, to solve the steam coils heating, the area of heat exchange is limited, and be static heating in large sewage lagoon, when the water yield was many in the pond, the waste water heat temperature raising in the pond was slow, DeGrain, the steam amount of expending is large simultaneously, and energy consumption is high, causes the problems such as cost rising of sewage disposal.

The utility model mainly is comprised of equalizing tank, sewer line, solving the technical scheme that its technical problem adopts is: set up sump pump and Slag filter at original equalizing tank water-in, increased simultaneously the triple-effect evaporator that is arranged in the production plant, be arranged on triple-effect evaporator and the sump pump that is arranged on the equalizing tank water-in in the production plant, valve all is set on the Slag filter, and equalizing tank, sump pump, Slag filter, valve and triple-effect evaporator are cascaded by sewer line each other and form a sewage temperature elevation system that circulates.

Positively effect of the present utility model is:

1, saved the thermal source steam that sewage plant sewage heats up, utilize this heating system, sewage plant consumption will reduce greatly, calculate to process 1000 side's waste water every day, if with steam sewage is warmed up to about 30 degree from the 16-17 degree every day, at least consume 30 tons of steam every day, calculated with 3 months winter, with more than 50 ten thousand yuan of minimum saving, utilizes thus this technology will greatly reduce the sewage disposal expense, saved resource, reduced consuming.

2, utilizing this heating system is the thing of killing two birds with one stone, and sewage plant is ensured by this device water temperature on the one hand; Save on the other hand the water resources to the vaporizer cooling, thereby avoided the consumption of water resources to run off.

3, utilize this temperature elevation system, avoided original sewage to utilize separately steam to come heat temperature raising, intensification efficient is improved greatly, also guaranteed the wastewater treatment efficiency of sewage plant.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is structural representation of the present utility model;

Among the figure: 1 equalizing tank, 2 sump pumps, 3 valves, 4 Slag filters, 5 triple-effect evaporators, 6 sewer lines.

Embodiment

As shown in Figure 1: set up sump pump 2 and Slag filter 4 at original equalizing tank 1 water-in, valve 3 is set on the Slag filter 4, increased simultaneously the triple-effect evaporator 5 that is arranged in the production plant, be arranged between triple-effect evaporator 5 and the sump pump 2 that is arranged on the equalizing tank water-in in the production plant and Slag filter and valve and be connected by pipeline 6, triple-effect evaporator 5 and sump pump 2 are cascaded with equalizing tank 1 by sewer line 6, valve 3, form a sewage intensification pipe network system that circulates.

During work, at first open the valve on Slag filter both sides, open sump pump 2, after sewage filters by Slag filter 4, through valve 3, flow out from the top after entering from triple-effect evaporator 5, enter pipeline 6 and enter sewage network, collect at last sewage works equalizing tank 1.

Principle of work of the present utility model: set up a sump pump (15kw at the sewage plant equalizing tank, 20 meters of lifts, flow 100 sides), after the Slag filter filtration, waste water enters vaporizer from the triple-effect evaporator bottom, after entering the inner tubulation of vaporizer, in the process of giving the cooling of triple-effect evaporator condenser, make the waste water water temperature obtain raising by heat exchange, flow out from vaporizer top behind the waste water absorbing heat, enter sewage network, again flow back to the sewage works equalizing tank.

Claims

1. sewage plant sewage heat riser, mainly formed by equalizing tank, sewer line and valve, it is characterized in that setting up sump pump and Slag filter at original equalizing tank water-in, increased simultaneously the triple-effect evaporator that is arranged in the production plant, equalizing tank, sump pump, Slag filter, valve and triple-effect evaporator are cascaded by sewer line each other and form a sewage temperature elevation system that circulates.

2. sewage plant sewage heat riser as claimed in claim 1 is characterized in that being arranged on triple-effect evaporator and the sump pump that is arranged on the equalizing tank water-in in the production plant, and valve all is set on the Slag filter.
