Description

Recycling device for coal gas residual heat
Technical field
The utility model relates to energy field, relates in particular to a kind of recycling device for coal gas residual heat.
Background technology
Fig. 1 is recycling device for coal gas residual heat structural representation in prior art, as shown in Figure 1, tradition coal gas waste heat reclaiming process flow process, all that desalted water in drum 1 passes into the lower drum 4 in heat pipe boiler 6 by tentiometer, get back to drum 1 with the hot water of lower drum 4 interior generations and the mixture of steam after coal gas heat exchange in heat pipe boiler 6, after steam separates with hot water, steam enter upper drum 3 in heat pipe boiler 6 again with heat pipe boiler 6 in coal gas heat exchange, the superheated steam producing is delivered to steam buffer tank 5, as steam in the boiler; Hot water in drum 1 passes into lower drum 4 by tentiometer repeatedly, in system, recycles, and adds new desalted water at regular time and quantity to drum simultaneously, supplements whole system water loss.
The shortcoming of this technique is: the one, and the interior heat transfer effect of heat pipe boiler 6 is not good, thereby causes the temperature of exit gas of heat pipe boiler 6 high; The 2nd, the steam production of collecting by steam buffer tank 5 is low; The 3rd, the aeration tower circulating cooling water consumption for further cooling coal gas waste heat being connected with heat pipe boiler 6 is large, causes recirculated cooling water power consumption high; The 4th, after heat pipe boiler heat exchange, its inner gas temperature is not low, thereby causes the resistance of coal gas exhaust system large.
Utility model content
The purpose of this utility model is to solve the defect that above-mentioned prior art exists, and a kind of good effect of heat exchange, recycling device for coal gas residual heat that Steam Recovery rate is high are provided.
A kind of recycling device for coal gas residual heat, comprise drum for storing desalted water, for collect steam steam buffer tank, be arranged on upper drum, lower drum in heat pipe boiler, drum is communicated with the entrance of described lower drum and the entrance of upper drum by pipeline respectively, the outlet of upper drum and the outlet of lower drum converge and are jointly communicated with the entrance of drum afterwards, and drum is communicated with steam buffer tank.
Further, recycling device for coal gas residual heat as above, described drum is communicated with the entrance of upper drum by heat-exchanger pump.
The recycling device for coal gas residual heat that the utility model provides, has the features such as device structure is simple, coal gas heat recovery rate is high, steam production is high, energy consumption is low, cost-saving.
Brief description of the drawings
Fig. 1 is recycling device for coal gas residual heat structural representation in prior art;
Fig. 2 is the utility model recycling device for coal gas residual heat structural representation.
Reference numeral:
1-drum, 2-heat-exchanger pump, 3-upper drum, 4-lower drum, 5-steam buffer tank, 6-heat pipe boiler.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model, technical scheme in the utility model is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 2 is the utility model recycling device for coal gas residual heat structural representation, as shown in Figure 2, the recycling device for coal gas residual heat that the utility model provides, comprise drum 1 for storing desalted water, for collect steam steam buffer tank 5, be arranged on upper drum 3, lower drum 4 in heat pipe boiler 6, described drum 1 is communicated with the entrance of described lower drum 4 and the entrance of upper drum 3 by pipeline respectively, the outlet of upper drum 3 and the outlet of lower drum 4 converge and are jointly communicated with the entrance of drum 1 afterwards, and drum 1 is communicated with steam buffer tank 5.
The operation principle of its device is: the upper and lower drum in heat pipe boiler all passes into desalted water by drum, desalted water in upper and lower drum in heat pipe boiler after coal gas of high temperature heat exchange, the hot water and steam producing jointly collects and enters drum, after drum separates vapour-liquid, steam flows to steam buffer tank to collect by pipeline, and the hot water separating is stayed in drum and continued to recycle.
Further, in order to improve the inflow of upper drum 3 interior desalted waters, described drum 1 is communicated with the entrance of upper drum 3 by heat-exchanger pump 2.
The utility model has been optimized the production procedure of coal gas heat recovery, the heat pipe boiler upper drum steam of not going further, but when the hot water part in drum is entered to lower drum by potential difference, another part pressurizes by heat-exchanger pump, and desalted water is sent into upper drum simultaneously.
The recycling device for coal gas residual heat that the utility model provides, because the desalted water in upper drum is carried by pipeline after heat-exchanger pump again, in course of conveying, the temperature of desalted water can be lower than directly entering water temperature in drum, therefore, desalted water in upper drum and the coal gas temperature difference are larger, so heat transfer effect is better, coal gas heat recovery rate is also higher, after this process implementing, the gas temperature of heat pipe boiler outlet reduces low, steam production is higher, and the scrubbing tower recirculated cooling water power consumption for cooling coal gas waste heat being connected with heat pipe boiler has reduced, also diminished for the induction system resistance that discharges coal gas.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
