The technical scheme is as follows: the sewage treatment device comprises a heat exchanger and a steam packet which are communicated, wherein a steam outlet is formed on the steam packet, a waste hot steam inlet and a waste hot air outlet are formed on two ends of the heat exchanger, a sewage water inlet and a sewage outlet are formed at the lower part of the heat exchanger, and tubes are uniformly arranged inside the heat exchanger. The utility model has energy conservation, low cost, and convenient use and maintenance, which ushers in the innovation of environmental protection equipment.

Description

A kind of gas furnace waste disposal plant

One, technical field

The utility model relates to environmental protection equipment, particularly a kind of gas furnace waste disposal plant.

Two, background technology

Producer gas generator is industrial coal vapourizing units commonly used such as fire-resistant factory, glasswork, ceramics factory, owing to contain a spot of water in the coal, this part water can be evaporated in the coal vaporescence, this part water that is evaporated is through the pollution of coal tar, in water, contain many objectionable constituent, form sewage.This sewage main harm composition has tar, aldehydes matter, ammonia nitriding compound, prussiate etc.Wherein the highest with aldehydes matter content, phenolic compound is a kind of prototype matter poisonous substance, volatilize, have irritating smell under the normal temperature, the aqueous solution is colourless, take on a red color after the oxidation, people and plant animal are all shown toxicity, can cause animals and plants death, the people contacts phenol solution or steam can cause poisoning, is the main component that causes environmental pollution.

This wastewater treatment method has burning method at present, extraction process, evaporation is used as vaporization agent method etc., burning method is feasible but power consumption is high, the extraction process complicated operation, being fit to handle the bigger enterprise of wastewater flow rate uses, the investment of handling waste water is also bigger, evaporation is as useful coal heating in the vaporization agent method, steam heating, with the coal gas heating etc. several different methods, but all there is the big problem of energy consumption, as number of patent application is 200720177815 patent, but owing to be to utilize water vapour to heat, has energy shortage, particularly to water vapour wretched insufficiency that winter, the gas furnace chuck produced, can't evaporate sewage, the patent No. is 200,720,027,375 1 kinds of phenol water evaporimeters, and this patent is to utilize the gas heat phenol-containing wastewater of heating, need transform gas line for existing gas furnace, contain simultaneously ash content and the more meeting of tar in the coal gas attached to needing frequent cleaning above the tubulation because the thinner increase cleaning of tubulation difficulty, so improvement and innovate imperative.

Three, utility model content

At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of gas furnace waste disposal plant, it is big effectively to solve existing sewage treatment equipment energy consumption, complicated operation, investment is big, the problem of difficult cleaning, the technical scheme of its solution is, comprises interchanger and steam pockets, and steam pockets is connected with interchanger, vapour outlet is arranged on the steam pockets, interchanger two ends have a surplus hot air intake and waste heat air, sewage import and sewage draining exit are arranged at the interchanger bottom, all are equipped with tubulation in the interchanger.The utility model is energy-conservation, and cost is low, and use, easy to maintenance is the innovation on the environmental protection equipment.

Four, description of drawings

Fig. 1 is structure of the present utility model (interchanger is cut an open) front view.

Fig. 2 is another example structure figure of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Provided by Fig. 1, the utility model comprises interchanger and steam pockets, and steam pockets 2 is connected with interchanger 4, vapour outlet 1 is arranged on the steam pockets 2, interchanger two ends have a surplus hot air intake 5 and waste heat air 9, sewage import 6 and sewage draining exit 8 are arranged at the interchanger bottom, all are equipped with tubulation 7 in the interchanger.

In order to guarantee result of use, the steam outlet pipe lower vertical of said vapour outlet 1 is contained on steam pockets 2 tops; On said steam pockets 2 outer walls liquidometer 3 is arranged; Said interchanger 4 is vertical or horizontal; Said waste hot air import 5 and waste heat air 9 are contained in (what provide among Fig. 1 is to be contained in two ends) on the interchanger one or both ends; Said steam pockets 2 is splits, or and interchanger link into an integrated entity (Fig. 1, Fig. 2 provide integrative-structure).

Principle of work of the present utility model is, filtered sewage enters in the interchanger from sewage import 6, elevation of water surface is no more than liquidometer 3 height, the waste heat air of stove enters in the heat exchanger tube from waste hot air import 5, the warm air waste heat is passed to sewage through tubulation, waste heat supply temperature is at 200-300 ℃, the sewage start vaporizer contains the phenol material and enters in the steam pockets 2 with water vapor together, after water vapor carries out the steam separation through steam pockets 2, steam enters the support equipment gas furnace through vapour outlet 1, enter atmosphere through waste heat air 9 by external chimney 12 through the residual air of heat exchange, the non-volatile material in the interchanger is discharged through sewage draining exit 8.

Fig. 2 is that another embodiment of the utility model and its structure difference shown in Figure 1 only are that recycle pump 11, water distributor 10 are arranged on the interchanger among Fig. 2, recycle pump makes the circulation down waterborne in the heat exchanger shell, the water distributor on interchanger top is evenly distributed on the tubulation wall water, quickens the vaporization of water.

Major advantage of the present utility model is:

1 can solve wastewater problem fully for the smaller gas furnace of wastewater flow rate.

2 obvious energy conservation utilize the waste heat of waste gas to heat, and do not increase enterprise energy consumption when solving contaminated wastewater.

3 realize automatic water supplement, and the personnel of need not keep an eye on, and save manpower and cost.

4 normal pressure equipment, convenient for installation and maintenance, equipment manufacturing cost is low.

The utility model is the equipment that carries out harmless treatment at the phenolic wastewater that gas furnace produces, mainly be to utilize coal gas contained heat energy of remaining waste gas behind kiln burning, sewage is heated, the phenol water vapor that the heating back produces enters gas furnace and uses as vaporization agent, through oily water separation and filtered sewage, send in the utility model, in the heat exchanger tube is hot waste gas, in the interchanger is sewage, the temperature of hot waste gas is 200-300 ℃, hot waste gas is given the heating of the sewage in the interchanger, water after the heating forms water vapor, water vapor is by steam pockets 2 in the heat exchanger shell, after in steam pockets 2, carrying out the carbonated drink separation, water is got back to interchanger, water vapor is sent into the bottom of gas furnace and is used as vaporization agent, the utility model is applicable to that the less gas furnace of phenol-containing wastewater amount uses, and wastewater flow rate can not surpass 30% of coal consumption, and the waste heat that utilizes stove to get rid of heats waste water, save energy not only, it is minimum that the processing costs of waste water is dropped to, and can realize automatic water supplement simultaneously, reduces manual work, the residual air temperature that this equipment uses is more than 100 ℃, use, easy to maintenance, cost is low, and economic and social benefit is remarkable.
